(Continued)

The ignition key and key rings, and

RKE transmitter, if equipped, are designed to work together as a system to reduce the risk of unintentionally moving the key out of the RUN position. The ignition key has a small hole to allow attachment of the provided key ring.

It is important that any replacement ignition keys have a small hole. See your dealer if a replacement key is required.

The combination and size of the rings that came with your keys were specifically selected for your vehicle. The rings are connected to the key like two links of a chain to reduce the risk of unintentionally moving the key out of the RUN position. Do not add any additional items to the ring attached to the ignition key. Attach additional items only to the second ring, and limit added items to a few essential keys or small, light items no larger than an RKE transmitter.

Warning

Do not let anyone ride where a seat belt cannot be worn properly.

In a crash, if you or your passenger(s) are not wearing seat belts, injuries can be much worse than if you are wearing seat belts. You can be seriously injured or killed by hitting things inside the vehicle harder or by being ejected from the vehicle. In addition, anyone who is not buckled up can strike other passengers in the vehicle.

It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, passengers riding in these areas are more likely to be seriously injured or killed. Do not allow

Why Seat Belts Work

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19

66 Seats and Restraints

When riding in a vehicle, you travel as fast as the vehicle does. If the vehicle stops suddenly, you keep going until something stops you.

It could be the windshield, the instrument panel, or the seat belts!

When you wear a seat belt, you and the vehicle slow down together.

There is more time to stop because you stop over a longer distance and, when worn properly, your strongest bones take the forces from the seat belts. That is why wearing seat belts makes such good sense.

Questions and Answers About

Seat Belts

Q: Will I be trapped in the vehicle after a crash if I am wearing a seat belt?

You

could

be — whether you are wearing a seat belt or not. Your chance of being conscious during and after a crash, so you

can

unbuckle and get out, is

much

greater if you are belted.

Q: If my vehicle has airbags, why should I have to wear seat belts?

Airbags are supplemental systems only. They work

with

seat belts — not instead of them.

Whether or not an airbag is provided, all occupants still have to buckle up to get the most protection.

Also, in nearly all states and in all Canadian provinces, the law requires wearing seat belts.

How to Wear Seat Belts

Properly

Follow these rules for everyone's protection.

There are additional things to know about seat belts and children, including smaller children and infants. If a child will be riding in the vehicle, see

Infants and Young Children

Review and follow the rules for children in addition to the following rules.

It is very important for all occupants to buckle up. Statistics show that unbelted people are hurt more often in crashes than those who are wearing seat belts.

There are important things to know about wearing a seat belt properly.

Sit up straight and always keep your feet on the floor in front of you (if possible).

Always use the correct buckle for your seating position.

Wear the lap part of the belt low and snug on the hips, just touching the thighs. In a crash,

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19 this applies force to the strong pelvic bones and you would be less likely to slide under the lap belt. If you slid under it, the belt would apply force on your abdomen. This could cause serious or even fatal injuries.

Wear the shoulder belt over the shoulder and across the chest.

These parts of the body are best able to take belt restraining forces. The shoulder belt locks if there is a sudden stop or crash.

{

Warning

You can be seriously injured, or even killed, by not wearing your seat belt properly.

Seats and Restraints 67

Never allow the lap or shoulder belt to become loose or twisted.

Never wear the shoulder belt under both arms or behind your back.

68 Seats and Restraints

Always use the correct buckle for your seating position.

{

Warning

The seat belt can be pinched if it is routed under plastic trim on the seat, such as trim around the rear seatback folding handle or side airbag. In a crash, pinched seat belts might not be able to provide adequate protection. Never allow seat belts to be routed under plastic trim pieces.

Lap-Shoulder Belt

All seating positions in the vehicle have a lap-shoulder belt.

The following instructions explain how to wear a lap-shoulder belt properly.

1. Adjust the seat, if the seat is adjustable, so you can sit up straight. To see how, see

“ Seats ” in the Index.

Never route the lap or shoulder belt over an armrest.

2. Pick up the latch plate and pull the belt across you. Do not let it get twisted.

The lap-shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly.

If the shoulder portion of a passenger belt is pulled out all the way, the child restraint locking feature may be engaged. See

Child Restraint

Systems

. If this occurs, let

the belt go back all the way and start again. If the locking

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19 feature stays engaged after letting the belt go back to stowed position on the seat, move the seat rearward or recline the seat until the shoulder belt retractor lock releases.

Engaging the child restraint locking feature in the front outboard seating position may affect the passenger sensing system, if equipped. See

Passenger Sensing System

If the webbing locks in the latch plate before it reaches the buckle, tilt the latch plate flat to unlock.

4. To make the lap part tight, pull up on the shoulder belt.

3. Push the latch plate into the buckle until it clicks.

Pull up on the latch plate to make sure it is secure. If the belt is not long enough, see

Seat Belt Extender

Position the release button on the buckle so that the seat belt could be quickly unbuckled if necessary.

13337620) - 2020 - CRC - 4/2/19

70 Seats and Restraints

To unlatch the belt, push the button on the buckle. The belt should return to its stowed position.

Always stow the seat belt slowly.

If the seat belt webbing returns quickly to the stowed position, the retractor may lock and cannot be pulled out. If this happens, pull the seat belt straight out firmly to unlock the webbing, and then release it.

If the webbing is still locked in the retractor, see your dealer.

Before a door is closed, be sure the seat belt is out of the way. If a door is slammed against a seat belt, damage can occur to both the seat belt and the vehicle.

Seat Belt Pretensioners

This vehicle has seat belt pretensioners for the front outboard occupants. Although the seat belt pretensioners cannot be seen, they are part of the seat belt assembly.

They can help tighten the seat belts during the early stages of a moderate to severe frontal, near frontal, or rear crash if the threshold conditions for pretensioner activation are met. Seat belt pretensioners can also help tighten the seat belts in a side crash or rollover event.

Pretensioners work only once. If the pretensioners activate in a crash, the pretensioners and probably other parts of the vehicle's seat belt system will need to be replaced.

See

Replacing Seat Belt System

Parts after a Crash

Do not sit on the outboard seat belt while entering or exiting the vehicle or at any time while sitting in the seat. Sitting on the seat belt can damage the webbing and hardware.

Rear Seat Belt Comfort Guides

Rear seat belt comfort guides may provide added seat belt comfort for older children who have outgrown booster seats and for some adults.

When installed on a shoulder belt, the comfort guide positions the shoulder belt away from the neck and head.

Comfort guides are available through your dealer for the rear outboard seating positions.

Instructions are included with the comfort guides.

Seat Belt Use During

Pregnancy

Seat belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they do not wear seat belts.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19

A pregnant woman should wear a lap-shoulder belt, and the lap portion should be worn as low as possible, below the rounding, throughout the pregnancy.

The best way to protect the fetus is to protect the mother. When a seat belt is worn properly, it is more likely that the fetus will not be hurt in a crash. For pregnant women, as for anyone, the key to making seat belts effective is wearing them properly.

Seat Belt Extender

If the vehicle's seat belt will fasten around you, you should use it.

But if a seat belt is not long enough, your dealer will order you an extender. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you. To help avoid personal injury, do not let someone else use it, and use it only for the seat it is made to fit. The extender has been designed for adults. Never use it for securing child restraints. For more information on the proper use and fit of seat belt extenders see the instruction sheet that comes with the extender.

Safety System Check

Periodically check the seat belt reminder, seat belts, buckles, latch plates, retractors, shoulder belt height adjusters (if equipped), and seat belt anchorages to make sure they are all in working order. Look for any other loose or damaged seat belt system parts that might keep a seat belt system from performing properly. See your dealer to have it repaired. Torn, frayed, or twisted seat belts may not protect you in a crash. Torn or frayed seat belts can rip apart under impact forces. If a belt is torn or frayed, have it replaced immediately. If a belt is twisted, it may be possible to untwist by reversing the latch plate on the webbing. If the twist cannot be corrected, ask your dealer to fix it.

Airbag System

The vehicle has the following airbags:

A frontal airbag for the driver

A frontal airbag for the front outboard passenger

A seat-mounted side impact airbag for the driver

A seat-mounted side impact airbag for the front outboard passenger

A roof-rail airbag for the driver and the passenger seated directly behind the driver

A roof-rail airbag for the front outboard passenger and the passenger seated directly behind the front outboard passenger

All vehicle airbags have the word

AIRBAG on the trim or on a label near the deployment opening.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19

For frontal airbags, the word

AIRBAG is on the center of the steering wheel for the driver and on the instrument panel for the front outboard passenger.

For seat-mounted side impact airbags, the word AIRBAG is on the side of the seatback or side of the seat closest to the door.

For roof-rail airbags, the word

AIRBAG is on the ceiling or trim.

Airbags are designed to supplement the protection provided by seat belts. Even though today's airbags are also designed to help reduce the risk of injury from the force of an inflating bag, all airbags must inflate very quickly to do their job.

Here are the most important things to know about the airbag system:

{

Warning

You can be severely injured or killed in a crash if you are not wearing your seat belt, even with

airbags. Airbags are designed to work with seat belts, not replace them. Also, airbags are not designed to inflate in every crash.

In some crashes seat belts are the only restraint. See

When

Should an Airbag Inflate?

Wearing your seat belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Airbags are “ supplemental restraints ” to the seat belts. Everyone in the vehicle should wear a seat belt properly, whether or not there is an airbag for that person.

Warning

Because airbags inflate with great force and faster than the blink of an eye, anyone who is up against, or very close to, any

airbag when it inflates can be seriously injured or killed. Do not sit unnecessarily close to any airbag, as you would be if sitting on the edge of the seat or leaning forward. Seat belts help keep you in position before and during a crash. Always wear a seat belt, even with airbags. The driver should sit as far back as possible while still maintaining control of the vehicle. The seat belts and the front outboard passenger airbags are most effective when you are sitting well back and upright in the seat with both feet on the floor.

Occupants should not lean on or sleep against the door or side windows in seating positions with seat-mounted side impact airbags and/or roof-rail airbags.

When Should an Airbag

Inflate?

This vehicle is equipped with airbags. See

Airbag System

Airbags are designed to inflate if the impact exceeds the specific airbag system's deployment threshold.

Deployment thresholds are used to predict how severe a crash is likely to be in time for the airbags to inflate and help restrain the occupants. The vehicle has electronic sensors that help the airbag system determine the severity of the impact. Deployment thresholds can vary with specific vehicle design.

Frontal airbags are designed to inflate in moderate to severe frontal or near frontal crashes to help reduce the potential for severe injuries, mainly to the driver's or front outboard passenger's head and chest.

Whether the frontal airbags will or should inflate is not based primarily on how fast the vehicle is traveling.

It depends on what is hit, the direction of the impact, and how quickly the vehicle slows down.

Frontal airbags may inflate at different crash speeds depending on whether the vehicle hits an object straight on or at an angle, and whether the object is fixed or moving, rigid or deformable, narrow or wide.

Frontal airbags are not intended to inflate during vehicle rollovers, rear impacts, or many side impacts.

In addition, the vehicle has advanced technology frontal airbags. Advanced technology frontal airbags adjust the restraint according to crash severity.

Seat-mounted side impact airbags are designed to inflate in moderate to severe side crashes depending on the location of the impact.

Seat-mounted side impact airbags are not designed to inflate in frontal impacts, near frontal impacts, rollovers, or rear impacts.

A seat-mounted side impact airbag is designed to inflate on the side of the vehicle that is struck.

Roof-rail airbags are designed to inflate in moderate to severe side crashes depending on the location of the impact. In addition, these roof-rail airbags are designed to inflate during a rollover or in a severe frontal impact. Roof-rail airbags are not designed to inflate in rear impacts. Both roof-rail airbags will inflate when either side of the vehicle is struck or if the sensing system predicts that the vehicle is about to roll over on its side, or in a severe frontal impact.

In any particular crash, no one can say whether an airbag should have inflated simply because of the vehicle damage or repair costs.

What Makes an Airbag

Inflate?

In a deployment event, the sensing system sends an electrical signal triggering a release of gas from the inflator. Gas from the inflator fills the

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19 airbag causing the bag to break out of the cover. The inflator, the airbag, and related hardware are all part of the airbag module.

For airbag locations, see

Where Are the Airbags?

How Does an Airbag

Restrain?

In moderate to severe frontal or near frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. In moderate to severe side collisions, even belted occupants can contact the inside of the vehicle.

Airbags supplement the protection provided by seat belts by distributing the force of the impact more evenly over the occupant's body.

Rollover capable roof-rail airbags are designed to help contain the head and chest of occupants in the outboard seating positions in the first and second rows. The rollover capable roof-rail airbags are designed to help reduce the risk of full or partial ejection in rollover events, although no system can prevent all such ejections.

But airbags would not help in many types of collisions, primarily because the occupant's motion is not toward those airbags. See

When

Should an Airbag Inflate?

Airbags should never be regarded as anything more than a supplement to seat belts.

What Will You See after an Airbag Inflates?

After frontal and seat-mounted side impact airbags inflate, they quickly deflate, so quickly that some people may not even realize the airbags inflated. Roof-rail airbags may still be at least partially inflated for some time after they inflate. Some components of the airbag module may be hot for several minutes. For location of the airbags, see

Where

Are the Airbags?

The parts of the airbag that come into contact with you may be warm, but not too hot to touch. There may

Seats and Restraints 77

be some smoke and dust coming from the vents in the deflated airbags. Airbag inflation does not prevent the driver from seeing out of the windshield or being able to steer the vehicle, nor does it prevent people from leaving the vehicle.

{

Warning

When an airbag inflates, there may be dust in the air. This dust could cause breathing problems for people with a history of asthma or other breathing trouble.

To avoid this, everyone in the vehicle should get out as soon as it is safe to do so. If you have breathing problems but cannot get out of the vehicle after an airbag inflates, then get fresh air by opening a window or a door.

If you experience breathing problems following an airbag deployment, you should seek medical attention.

The vehicle has a feature that may automatically unlock the doors, turn on the interior lamps and hazard warning flashers, and shut off the fuel system after the airbags inflate.

The feature may also activate, without airbag inflation, after an event that exceeds a predetermined threshold. After turning the ignition off and then on again, the fuel system will return to normal operation; the doors can be locked, the interior lamps can be turned off, and the hazard warning flashers can be turned off using the controls for those features. If any of these systems are damaged in the crash they may not operate as normal.

{

Warning

A crash severe enough to inflate the airbags may have also damaged important functions in the vehicle, such as the fuel system, brake and steering systems, etc. Even if the vehicle appears to be drivable after a

(Continued)

Warning (Continued)

moderate crash, there may be concealed damage that could make it difficult to safely operate the vehicle.

Use caution if you should attempt to restart the engine after a crash has occurred.

In many crashes severe enough to inflate the airbag, windshields are broken by vehicle deformation.

Additional windshield breakage may also occur from the front outboard passenger airbag.

Airbags are designed to inflate only once. After an airbag inflates, you will need some new parts for the airbag system.

If you do not get them, the airbag system will not be there to help protect you in another crash. A new system will include airbag modules and possibly other parts. The service manual for the vehicle covers the need to replace other parts.

The vehicle has a crash sensing and diagnostic module which records information after a crash. See

The words ON and OFF, or the symbols for on and off, will be visible during the system check.

When the system check is complete, either the word ON or

OFF, or the symbol for on or off, will be visible. See

Passenger Airbag

Status Indicator

136

The passenger sensing system turns off the front outboard passenger frontal airbag under certain conditions. No other airbag is affected by the passenger sensing system.

The passenger sensing system works with sensors that are part of the front outboard passenger seat and seat belt. The sensors are designed to detect the presence of a properly seated occupant and determine if the front outboard passenger frontal airbag should be allowed to inflate or not.

According to accident statistics, children are safer when properly secured in a rear seat in the correct child restraint for their weight and size.

Whenever possible, children aged

12 and under should be secured in a rear seating position.

Never put a rear-facing child seat in the front. This is because the risk to the rear-facing child is so great, if the airbag inflates.

{

Warning

A child in a rear-facing child restraint can be seriously injured or killed if the passenger frontal

Warning (Continued)

airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. A child in a forward-facing child restraint can be seriously injured or killed if the passenger frontal airbag inflates and the passenger seat is in a forward position.

Even if the passenger sensing system has turned off the passenger frontal airbag, no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance, even though the airbag is turned off.

Never put a rear-facing child restraint in the front seat, even if the airbag is off. If securing a forward-facing child restraint in the front outboard passenger seat, always move the seat as far back as it will go. It is better to

secure child restraints in the rear seat. Consider using another vehicle to transport the child when a rear seat is not available.

If the vehicle does not have a rear seat that will accommodate a rear-facing child restraint, a rear-facing child restraint should not be installed in the vehicle, even if the airbag is off.

The passenger sensing system is designed to turn off the front outboard passenger frontal airbag if:

The front outboard passenger seat is unoccupied.

The system determines an infant is present in a child restraint.

A front outboard passenger takes his/her weight off of the seat for a period of time.

There is a critical problem with the airbag system or the passenger sensing system.

When the passenger sensing system has turned off the front outboard passenger frontal airbag, the OFF indicator will light and stay lit as a reminder that the airbag is off. See

The passenger sensing system is designed to turn on the front outboard passenger frontal airbag anytime the system senses that a person of adult size is sitting properly in the front outboard passenger seat.

When the passenger sensing system has allowed the airbag to be enabled, the ON indicator will light and stay lit as a reminder that the airbag is active.

For some children, including children in child restraints, and for very small adults, the passenger sensing system may or may not turn off the front outboard passenger frontal airbag, depending upon the person's seating posture and body build. Everyone in the vehicle who has outgrown child restraints should wear a seat belt properly — whether or not there is an airbag for that person.

Make sure the seat belt retractor is locked by pulling the shoulder belt all the way out of the retractor when installing the child restraint, even if the child restraint is equipped with a seat belt lock off. When the retractor lock is set, the belt can be tightened but not pulled out of the retractor.

5. If, after reinstalling the child restraint and restarting the vehicle, the ON indicator is still lit, turn the vehicle off. Then slightly recline the vehicle seatback and adjust the seat cushion, if adjustable, to make sure that the vehicle seatback is not pushing the child restraint into the seat cushion.

Also make sure the child restraint is not trapped under the vehicle head restraint.

If this happens, adjust the head restraint. See

Head Restraints

6. Restart the vehicle.

The passenger sensing system may or may not turn off the airbag for a child in a child restraint depending upon the child ’ s size. It is better to secure child restraints in the rear seat. Consider using another vehicle to transport the child when a rear seat is not available. Never put a rear-facing child restraint in the front seat, even if the ON indicator is not lit.

Seats and Restraints 81

If the Off Indicator Is Lit for an

Adult-Sized Occupant

If a person of adult size is sitting in the front outboard passenger seat, but the OFF indicator is lit, it could be because that person is not sitting properly in the seat or that the child restraint locking feature is engaged.

Use the following steps to allow the system to detect that person and enable the front outboard passenger frontal airbag:

1. Turn the vehicle off.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19

82 Seats and Restraints

2. Remove any additional material from the seat, such as blankets, cushions, seat covers, seat heaters, or seat massagers.

3. Place the seatback in the fully upright position.

4. Have the person sit upright in the seat, centered on the seat cushion, with legs comfortably extended.

5. If the shoulder portion of the belt is pulled out all the way, the child restraint locking feature will be engaged. This may unintentionally cause the passenger sensing system to turn the airbag off for some adult-sized occupants. If this happens, unbuckle the belt, let the belt go back all the way, and then buckle the belt again without pulling the belt out all the way.

6. Restart the vehicle and have the person remain in this position for two to three minutes after the ON indicator is lit.

{

Warning

If the front outboard passenger airbag is turned off for an adult-sized occupant, the airbag will not be able to inflate and help protect that person in a crash, resulting in an increased risk of serious injury or even death. An adult-sized occupant should not ride in the front outboard passenger seat, if the passenger airbag OFF indicator is lit.

Additional Factors Affecting

System Operation

Seat belts help keep the passenger in position on the seat during vehicle maneuvers and braking, which helps the passenger sensing system maintain the passenger airbag status. See “ Seat Belts ” and

“ Child Restraints ” in the Index for additional information about the importance of proper restraint use.

A thick layer of additional material, such as a blanket or cushion, or aftermarket equipment such as seat covers, seat heaters, and seat massagers can affect how well the passenger sensing system operates. We recommend that you not use seat covers or other aftermarket equipment except when approved by GM for your specific vehicle. See

Adding Equipment to the Airbag-Equipped Vehicle

for more information about modifications that can affect how the system operates.

The ON indicator may be lit if an object, such as a briefcase, handbag, grocery bag, laptop, or other electronic device, is put on an unoccupied seat. If this is not desired, remove the object from the seat.

are close to an airbag when it inflates. Avoid yellow connectors.

They are probably part of the airbag system. Be sure to follow proper service procedures, and make sure the person performing work for you is qualified to do so.

Adding Equipment to the

Airbag-Equipped Vehicle

Adding accessories that change the vehicle's frame, bumper system, height, front end, or side sheet metal, may keep the airbag system from working properly.

The operation of the airbag system can also be affected by changing, including improperly repairing or replacing, any parts of the following:

Airbag system, including airbag modules, front or side impact sensors, sensing and diagnostic module, or airbag wiring

Seats and Restraints 83

Front seats, including stitching, seams, or zippers

Seat belts

Steering wheel, instrument panel, overhead console, ceiling trim, or pillar garnish trim

Inner door seals, including speakers

Your dealer and the service manual have information about the location of the airbag modules and sensors, sensing and diagnostic module, and airbag wiring along with the proper replacement procedures.

In addition, the vehicle has a passenger sensing system for the front outboard passenger position, which includes sensors that are part of the passenger seat. The passenger sensing system may not operate properly if the original seat trim is replaced with non-GM covers, upholstery, or trim; or with

GM covers, upholstery, or trim designed for a different vehicle. Any object, such as an aftermarket seat heater or a comfort-enhancing pad or device, installed under or on top

Child Restraints

Older Children

Older children who have outgrown booster seats should wear the vehicle ’ s seat belts.

The manufacturer instructions that come with the booster seat state the weight and height limitations for that booster. Use a booster seat with a lap-shoulder belt until the child passes the fit test below:

Seats and Restraints 85

Sit all the way back on the seat.

Do the knees bend at the seat edge? If yes, continue. If no, return to the booster seat.

Buckle the lap-shoulder belt.

Does the shoulder belt rest on the shoulder? If yes, continue.

If no, try using the rear seat belt comfort guide, if available. See

“ Rear Seat Belt Comfort Guides ” under

Lap-Shoulder Belt

If a comfort guide is not available, or if the shoulder belt still does not rest on the shoulder, then return to the booster seat.

Does the lap belt fit low and snug on the hips, touching the thighs? If yes, continue. If no, return to the booster seat.

Can proper seat belt fit be maintained for the length of the trip? If yes, continue. If no, return to the booster seat.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19

86 Seats and Restraints

Q: What is the proper way to wear seat belts?

An older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs.

This applies belt force to the child's pelvic bones in a crash.

It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash.

Also see “ Rear Seat Belt Comfort

Guides ” under

Lap-Shoulder Belt

According to accident statistics, children are safer when properly restrained in a rear seating position.

In a crash, children who are not buckled up can strike other people who are buckled up, or can be thrown out of the vehicle. Older children need to use seat belts properly.

{

Warning

Never allow more than one child to wear the same seat belt. The seat belt cannot properly spread the impact forces. In a crash, they can be crushed together and seriously injured. A seat belt must be used by only one person at a time.

{

Warning

Never allow a child to wear the seat belt with the shoulder belt behind their back. A child can be seriously injured by not wearing the lap-shoulder belt properly. In a crash, the child would not be restrained by the shoulder belt.

The child could move too far forward increasing the chance of head and neck injury. The child might also slide under the lap belt. The belt force would then be applied right on the abdomen.

That could cause serious or fatal injuries. The shoulder belt should go over the shoulder and across the chest.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19

Infants and Young

Children

Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.

{

Warning

Children can be seriously injured or strangled if a shoulder belt is wrapped around their neck. The shoulder belt can tighten but cannot be loosened if it is locked.

The shoulder belt locks when it is pulled all the way out of the retractor. It unlocks when the shoulder belt is allowed to go all the way back into the retractor, but it cannot do this if it is wrapped around a child ’ s neck.

If the shoulder belt is locked and tightened around a child ’ s neck, the only way to loosen the belt is to cut it.

Never leave children unattended in a vehicle and never allow children to play with the seat belts.

Every time infants and young children ride in vehicles, they should have the protection provided by

Seats and Restraints 87

appropriate child restraints. Neither the vehicle's seat belt system nor its airbag system is designed for them.

Children who are not restrained properly can strike other people, or can be thrown out of the vehicle.

{

Warning

Never hold an infant or a child while riding in a vehicle. Due to crash forces, an infant or a child will become so heavy it is not possible to hold it during a crash.

For example, in a crash at only

40 km/h (25 mph), a 5.5 kg (12 lb) infant will suddenly become a

110 kg (240 lb) force on a person's arms. An infant or child should be secured in an appropriate child restraint.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19

88 Seats and Restraints

{

Warning

Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Never put a rear-facing child restraint in the front outboard seat. Secure a rear-facing child restraint in a rear seat. It is also better to secure a forward-facing child restraint in a rear seat. If you must secure a forward-facing child restraint in the front outboard seat, always move the front passenger seat as far back as it will go.

Child restraints are devices used to restrain, seat, or position children in the vehicle and are sometimes called child seats or car seats.

There are three basic types of child restraints:

Forward-facing child restraints

Rear-facing child restraints

Belt-positioning booster seats

The proper child restraint for your child depends on their size, weight, and age, and also on whether the child restraint is compatible with the vehicle in which it will be used.

For each type of child restraint, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle. If it is, the child restraint will have a label saying that it meets federal motor vehicle safety standards.

The instruction manual that is provided with the child restraint states the weight and height limitations for that particular child restraint. In addition, there are many kinds of child restraints available for children with special needs.

{

Warning

To reduce the risk of neck and head injury in a crash, infants and toddlers should be secured in a rear-facing child restraint until age two, or until they reach the maximum height and weight limits of their child restraint.

13337620) - 2020 - CRC - 4/2/19

Seats and Restraints 89

{

Warning

A young child's hip bones are still so small that the vehicle seat belt may not remain low on the hip bones, as it should. Instead, it may settle up around the child's abdomen. In a crash, the belt would apply force on a body area that is unprotected by any bony structure. This alone could cause serious or fatal injuries. To reduce the risk of serious or fatal injuries during a crash, young children should always be secured in an appropriate child restraint.

Child Restraint Systems

Rear-Facing Infant Restraint

A rear-facing child restraint provides restraint with the seating surface against the back of the infant.

The harness system holds the infant in place and, in a crash, acts to keep the infant positioned in the restraint.

Forward-Facing Child Restraint

A forward-facing child restraint provides restraint for the child's body with the harness.

90 Seats and Restraints

Booster Seats

A belt-positioning booster seat is used for children who have outgrown their forward-facing child restraint. Boosters are designed to improve the fit of the vehicle's seat belt system until the child is large enough for the vehicle seat belts to fit properly without a booster seat.

Securing an Add-On Child

Restraint in the Vehicle

{

Warning

A child can be seriously injured or killed in a crash if the child restraint is not properly secured in the vehicle. Secure the child restraint properly in the vehicle using the vehicle seat belt or

LATCH system, following the instructions that came with that child restraint and the instructions in this manual.

To help reduce the chance of injury, the child restraint must be secured in the vehicle. Child restraints must be secured in vehicle seats by lap belts or the lap belt portion of a lap-shoulder belt, or by the LATCH system. See

Lower Anchors and

Tethers for Children (LATCH

System)

for more information.

Children can be endangered in a crash if the child restraint is not properly secured in the vehicle.

When securing an add-on child restraint, refer to the following:

1. Instruction labels provided on the child restraint

2. Instruction manual provided with the child restraint

3. This vehicle owner's manual

The child restraint instructions are important, so if they are not available, obtain a replacement copy from the manufacturer.

Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in the vehicle — even when no child is in it.

In some areas Certified Child

Passenger Safety Technicians

(CPSTs) are available to inspect and demonstrate how to correctly use and install child restraints. In the U.S., refer to the National

Highway Traffic Safety

Administration (NHTSA) website to locate the nearest child safety seat

Transport Canada or the Provincial

Ministry of Transportation office.

Securing the Child Within the

Child Restraint

{

Warning

A child can be seriously injured or killed in a crash if the child is not properly secured in the child restraint. Secure the child properly following the instructions that came with that child restraint.

Where to Put the

Restraint

According to accident statistics, children and infants are safer when properly restrained in an appropriate child restraint secured in a rear seating position.

Whenever possible, children aged

12 and under should be secured in a rear seating position.

Never put a rear-facing child restraint in the front. This is because the risk to the rear-facing child is so great if the airbag deploys.

{

Warning

A child in a rear-facing child restraint can be seriously injured or killed if the front passenger airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. A child in a forward-facing child restraint can be seriously injured or killed if the front passenger airbag inflates and the passenger seat is in a forward position.

Even if the passenger sensing system has turned off the front passenger frontal airbag, no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off.

(Continued)

Seats and Restraints 91

Warning (Continued)

Secure rear-facing child restraints in a rear seat, even if the airbag is off. If you secure a forward-facing child restraint in the front seat, always move the front passenger seat as far back as it will go. It is better to secure the child restraint in a rear seat.

See

Passenger Sensing System

for additional information.

{

Warning

A child in a child restraint in the center front seat can be badly injured or killed by the frontal airbags if they inflate. Never secure a child restraint in the center front seat. It is always better to secure a child restraint in a rear seat.

Do not use child restraints in the center front seat position.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19

92 Seats and Restraints

If the vehicle does not have a rear seat that will accommodate a rear-facing child restraint, a rear-facing child restraint should not be installed in the vehicle, even if the airbag is off.

When securing a child restraint with the seat belts in a rear seat position, study the instructions that came with the child restraint to make sure it is compatible with this vehicle.

Child restraints and booster seats vary considerably in size, and some may fit in certain seating positions better than others.

Depending on where you place the child restraint and the size of the child restraint, you may not be able to access adjacent seat belts or

LATCH anchors for additional passengers or child restraints.

Adjacent seating positions should not be used if the child restraint prevents access to or interferes with the routing of the seat belt.

Wherever a child restraint is installed, be sure to follow the instructions that came with the child restraint and secure the child restraint properly.

Lower Anchors and

Tethers for Children

(LATCH System)

The LATCH system secures a child restraint during driving or in a crash.

LATCH attachments on the child restraint are used to attach the child restraint to the anchors in the vehicle. This system is designed to make installation of a child restraint easier.

In order to use the LATCH system in your vehicle, you need a child restraint that has LATCH attachments. LATCH-compatible rear-facing and forward-facing child seats can be properly installed using either the LATCH anchors or the vehicle ’ s seat belts. Do not use both the seat belts and the LATCH anchorage system to secure a rear-facing or forward-facing child seat.

Booster seats use the vehicle ’ s seat belts to secure the child and the booster seat. If the manufacturer recommends that the booster seat be secured with the LATCH system, this can be done as long as the booster seat can be positioned properly and there is no interference with the proper positioning of the lap-shoulder belt on the child.

Make sure to follow the instructions that came with the child restraint, and also the instructions in this manual.

When installing a child restraint with a top tether, you must also use either the lower anchors or the seat belts to properly secure the child restraint. A child restraint must never be installed using only the top tether.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19

For a forward-facing 5-pt harness child restraint where the combined weight of the child and restraint are up to 29.5 kg (65 lb), use either the lower LATCH anchorages with the top tether anchorage, or the seat belt with the top tether anchorage.

Where the combined weight of the

Lower Anchor and Top Tether

Anchor Locations

Lower anchors (1) are metal bars built into the vehicle. There are two lower anchors for each LATCH seating position that will accommodate a child restraint with lower attachments (2).

A top tether (3, 4) is used to secure the top of the child restraint to the vehicle. A top tether anchor is built into the vehicle. The top tether attachment hook (2) on the child restraint connects to the top tether anchor in the vehicle in order to reduce the forward movement and rotation of the child restraint during driving or in a crash.

The child restraint may have a single tether (3) or a dual tether (4).

Either will have a single attachment hook (2) to secure the top tether to the anchor.

Replacing LATCH System

Parts After a Crash

{

Warning

A crash can damage the LATCH system in the vehicle. A damaged

LATCH system may not properly secure the child restraint, resulting in serious injury or even death in a crash. To help make sure the LATCH system is working properly after a crash, see your dealer to have the system inspected and any necessary replacements made as soon as possible.

If the vehicle has the LATCH system and it was being used during a crash, new LATCH system parts may be needed.

New parts and repairs may be necessary even if the LATCH system was not being used at the time of the crash.

Securing Child Restraints

(With the Seat Belt in the

Rear Seat)

When securing a child restraint with the seat belts in a rear seat position, study the instructions that came with the child restraint to make sure it is compatible with this vehicle.

If the child restraint has the LATCH system, see

Lower Anchors and

Tethers for Children (LATCH

System)

for how and where to install the child restraint using

LATCH. If a child restraint is secured in the vehicle using a seat belt and it uses a top tether, see

Lower

Anchors and Tethers for Children

(LATCH System)

for top tether anchor locations.

Do not secure a child seat in a position without a top tether anchor if a national or local law requires that the top tether be anchored, or if the instructions that come with the child restraint say that the top tether must be anchored.

Seats and Restraints 105

In Canada, the law requires that forward-facing child restraints have a top tether, and that the tether be attached.

If the child restraint or vehicle seat position does not have the LATCH system, you will be using the seat belt to secure the child restraint. Be sure to follow the instructions that came with the child restraint.

If more than one child restraint needs to be installed in the rear seat, be sure to read

Where to Put the Restraint

Double Cab

1. Remove the head restraint or headrest prior to installing a forward-facing child restraint in an outboard rear seating position. See “ Head Restraint or Headrest Removal and

Securing Child Restraints

(In the Center Front Seat)

{

Warning

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19

Do not use child restraints in the center front seat position.

Securing Child Restraints

(With the Seat Belt in the

Front Passenger Seat)

This vehicle has airbags. A rear seat is a safer place to secure a forward-facing child restraint. See

Where to Put the Restraint

In addition, the vehicle has a passenger sensing system which is designed to turn off the front outboard passenger frontal airbag under certain conditions. See

Passenger Sensing System

and

Passenger Airbag Status Indicator

136

for more information, including important safety information.

Never put a rear-facing child restraint in the front. This is because the risk to the rear-facing child is so great, if the airbag deploys.

{

Warning

A child in a rear-facing child restraint can be seriously injured or killed if the front outboard passenger frontal airbag inflates.

This is because the back of the rear-facing child restraint would be very close to the inflating airbag. A child in a forward-facing child restraint can be seriously injured or killed if the front outboard passenger frontal airbag inflates and the passenger seat is in a forward position.

Even if the passenger sensing system has turned off the front outboard passenger frontal airbag, no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off.

Secure rear-facing child restraints in a rear seat, even if the airbag is off. If you secure a

Seats and Restraints 109

Warning (Continued)

forward-facing child restraint in the front outboard passenger seat, always move the seat as far back as it will go. It is better to secure the child restraint in a rear seat.

See

Passenger Sensing System

for additional information.

If the vehicle does not have a rear seat that will accommodate a rear-facing child restraint, a rear-facing child restraint should not be installed in the vehicle, even if the airbag is off.

If the child restraint uses a top tether, see

Lower Anchors and

Tethers for Children (LATCH

System)

for top tether anchor locations.

Do not secure a child seat in a position without a top tether anchor if a national or local law requires that the top tether be anchored, or if

the instructions that come with the child restraint say that the top tether must be anchored.

In Canada, the law requires that forward-facing child restraints have a top tether, and that the tether be attached.

When using the lap-shoulder belt to secure the child restraint in this position, follow the instructions that came with the child restraint and the following instructions:

1. Move the seat as far back as it will go before securing the forward-facing child restraint.

Move the seat upward or the seatback to an upright position, if needed, to get a tight installation of the child restraint.

When the passenger sensing system has turned off the front outboard passenger frontal airbag, the OFF indicator on the passenger airbag status indicator should light and stay lit when you start the vehicle.

See

2. Put the child restraint on the seat.

3. Pick up the latch plate, and run the lap and shoulder portions of the vehicle seat belt through or around the child restraint.

The child restraint instructions will show you how.

Tilt the latch plate to adjust the belt if needed.

4. Push the latch plate into the buckle until it clicks.

Position the release button on the buckle, away from the child restraint, so that the seat belt could be quickly unbuckled if necessary.

Compass

The vehicle may have a compass display on the Driver Information

Center (DIC). The compass receives its heading and other information from the Global Positioning

System (GPS) antenna, Electronic

Stability Control (ESC), and vehicle speed information.

The compass system is designed to operate for a certain number of miles or degrees of turn before needing a signal from the GPS satellites. When the compass display shows CAL, drive the vehicle for a short distance in an open area where it can receive a

GPS signal. The compass system will automatically determine when a

GPS signal is restored and provide a heading again.

At the service station, the fuel pump shuts off before the gauge reads full.

It takes a little more or less fuel to fill up than the gauge indicated. For example, the gauge may have indicated the tank was half full, but it actually took a little more or less than half the tank's capacity to fill the tank.

The gauge moves a little while turning a corner or speeding up.

The gauge takes a few seconds to stabilize after the ignition is turned on, and goes back to empty when the ignition is turned off.

The voltmeter gauge may also read lower when in fuel economy mode.

This is normal.

Readings outside the normal operating range can also occur when a large number of electrical accessories are operating in the vehicle and the engine is left idling for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power.

The vehicle can only be driven for a short time with the readings outside the normal operating range. If the vehicle must be driven, turn off all accessories, such as the radio and air conditioner.

Readings outside the normal operating range indicate a possible problem in the electrical system.

Have the vehicle serviced as soon as possible.

Universal Remote System

Programming

If equipped, these buttons are in the overhead console.

This system can replace up to three remote control transmitters used to activate devices such as garage door openers, security systems, and home automation devices. These

Instruments and Controls 161

instructions refer to a garage door opener, but can be used for other devices.

Do not use the Universal Remote system with any garage door opener that does not have the stop and reverse feature. This includes any garage door opener model manufactured before April 1, 1982.

Read the instructions completely before programming the Universal

Remote system. It may help to have another person assist with the programming process.

Keep the original hand-held transmitter for use in other vehicles as well as for future programming.

Erase the programming when vehicle ownership is terminated.

See “ Erasing Universal Remote

System Buttons ” later in this section.

To program a garage door opener, park outside directly in line with and facing the garage door opener receiver. Clear all people and objects near the garage door.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19

162 Instruments and Controls

Make sure the hand-held transmitter has a new battery for quick and accurate transmission of the radio-frequency signal.

Programming the Universal

Remote System

For questions or programming help, see www.homelink.com/gm or call

1-800-355-3515. For calls placed outside the U.S., Canada, or Puerto

Rico, international rates will apply and may differ based on landline or mobile phone.

Programming involves time-sensitive actions, and may time out causing the procedure to be repeated.

To program up to three devices:

1. Hold the end of the hand-held transmitter about 3 to 8 cm (1 to 3 in) away from the

Universal Remote system buttons with the indicator light in view. The hand-held transmitter was supplied by the manufacturer of the garage door opener receiver.

2. At the same time, press and hold both the hand-held transmitter button and one of the three Universal Remote system buttons to be used to operate the garage door. Do not release either button until the indicator light goes from a slow to a rapid flashing light.

Then release both buttons.

Some garage door openers may require substitution of

Step 2 with the procedure under “ Radio Signals for Some

Gate Operators ” later in this section.

3. Press and hold the newly programmed Universal Remote system button for five seconds while watching the indicator light and garage door activation.

If the indicator light stays on continuously or the garage door moves when the button is pressed, then programming is complete.

There is no need to complete Steps 4 – 6.

If the indicator light does not come on or the garage door does not move, a second button press may be required. For a second time, press and hold the newly programmed button for five seconds. If the light stays on or the garage door moves, programming is complete.

If the indicator light blinks rapidly for two seconds, then changes to a solid light and the garage door does not move, continue with programming Steps 4 – 6.

Learn or Smart Button

4. After completing Steps 1 – 3, locate the Learn or Smart button inside the garage on the garage door opener receiver.

The name and color of the button may vary by manufacturer.

5. Press and release the Learn or

Smart button. Step 6 must be completed within 30 seconds of pressing this button.

6. Inside the vehicle, press and hold the newly programmed

Universal Remote system button for two seconds and then release it. If the garage door does not move or the lamp on the garage door opener receiver does not flash, press and hold the same button a second time for two seconds, then release it.

Again, if the door does not move or the garage door lamp does not flash, press and hold the same button a third time for two seconds, then release it.

The Universal Remote system should now activate the garage door.

Repeat the process for programming the two remaining buttons.

Battery Load

Management

The vehicle has Electric Power

Management (EPM), which estimates the battery's temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery.

When the battery's state of charge is low, the voltage is raised slightly to quickly bring the charge back up.

When the state of charge is high, the voltage is lowered slightly to prevent overcharging. The voltmeter gauge or the voltage display on the

Driver Information Center (DIC), if equipped, may show the voltage

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19 moving up or down. This is normal.

If there is a problem, an alert will be displayed.

The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles.

This is because the generator

(alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads.

A high electrical load occurs when several of the following are on, such as: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets.

EPM works to prevent excessive discharge of the battery. It does this by balancing the generator's output and the vehicle's electrical needs.

It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories.

Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a DIC message might be displayed and it is recommended that the driver reduce the electrical loads as much as possible.

Battery Power Protection

This feature shuts off the dome and reading lamps, if they are left on for more than 10 minutes after the ignition is turned off. The cargo lamp shuts off after 20 minutes. This prevents the battery from running down.

Service

All vehicles have a label underhood that identifies the refrigerant used in the vehicle. The refrigerant system should only be serviced by trained and certified technicians. The air conditioning evaporator should never be repaired or replaced by one from a salvage vehicle.

It should only be replaced by a new evaporator to ensure proper and safe operation.

During service, all refrigerants should be reclaimed with proper equipment. Venting refrigerants directly to the atmosphere is harmful to the environment and may also create unsafe conditions based on inhalation, combustion, frostbite, or other health-based concerns.

The air conditioning system requires periodic maintenance. See

Maintenance Schedule

Driving Information

Driving for Better Fuel

Economy

Driving habits can affect fuel mileage. Here are some driving tips to get the best fuel economy possible:

Set the climate controls to the desired temperature after the engine is started, or turn them off when not required.

Avoid fast starts and accelerate smoothly.

Brake gradually and avoid abrupt stops.

Avoid idling the engine for long periods of time.

When road and weather conditions are appropriate, use cruise control.

Always follow posted speed limits or drive more slowly when conditions require.

Keep vehicle tires properly inflated.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

Combine several trips into a single trip.

Replace the vehicle's tires with the same TPC Spec number molded into the tire's sidewall near the size.

Follow recommended scheduled maintenance.

Distracted Driving

Distraction comes in many forms and can take your focus from the task of driving. Exercise good judgment and do not let other activities divert your attention away from the road. Many local governments have enacted laws regarding driver distraction. Become familiar with the local laws in your area.

To avoid distracted driving, keep your eyes on the road, keep your hands on the steering wheel, and focus your attention on driving.

Do not use a phone in demanding driving situations.

Use a hands-free method to place or receive necessary phone calls.

Watch the road. Do not read, take notes, or look up information on phones or other electronic devices.

Designate a front seat passenger to handle potential distractions.

Become familiar with vehicle features before driving, such as programming favorite radio stations and adjusting climate control and seat settings.

Program all trip information into any navigation device prior to driving.

Wait until the vehicle is parked to retrieve items that have fallen to the floor.

Stop or park the vehicle to tend to children.

Keep pets in an appropriate carrier or restraint.

Driving and Operating 187

Avoid stressful conversations while driving, whether with a passenger or on a cell phone.

{

Warning

Taking your eyes off the road too long or too often could cause a crash resulting in injury or death.

Focus your attention on driving.

Refer to the infotainment manual for more information on using that system and the navigation system, if equipped, including pairing and using a cell phone.

Defensive Driving

Defensive driving means “ always expect the unexpected.

” The first step in driving defensively is to wear the seat belt. See

Seat Belts

Assume that other road users

(pedestrians, bicyclists, and other drivers) are going to be careless and make mistakes.

Anticipate what they might do and be ready.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

188 Driving and Operating

Allow enough following distance between you and the driver in front of you.

Focus on the task of driving.

Drunk Driving

Death and injury associated with drinking and driving is a global tragedy.

{

Warning

Drinking and then driving is very dangerous. Your reflexes, perceptions, attentiveness, and judgment can be affected by even a small amount of alcohol. You can have a serious — or even fatal — collision if you drive after drinking.

Do not drink and drive or ride with a driver who has been drinking.

Ride home in a cab; or if you are with a group, designate a driver who will not drink.

Control of a Vehicle

Braking, steering, and accelerating are important factors in helping to control a vehicle while driving.

Braking

Braking action involves perception time and reaction time. Deciding to push the brake pedal is perception time. Actually doing it is reaction time.

Average driver reaction time is about three-quarters of a second. In that time, a vehicle moving at

100 km/h (60 mph) travels 20 m

(66 ft), which could be a lot of distance in an emergency.

Helpful braking tips to keep in mind include:

Keep enough distance between you and the vehicle in front of you.

Avoid needless heavy braking.

Keep pace with traffic.

If the engine ever stops or a brake fault occurs, the brakes may lose power assist. More effort will be required to stop the vehicle. It may take longer to stop.

Steering

Caution

To avoid damage to the steering system, do not drive over curbs, parking barriers, or similar objects at speeds greater than 3 km/h

(1 mph). Use care when driving over other objects such as lane dividers and speed bumps.

Damage caused by misuse of the vehicle is not covered by the vehicle warranty.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

Electric Power Steering (1500

Series)

This vehicle has electric power steering. It does not have power steering fluid. Regular maintenance is not required.

If power steering assist is lost due to a system malfunction, the vehicle can be steered, but may require increased effort.

See your dealer if there is a problem.

If the steering assist is used for an extended period of time while the vehicle is not moving, power assist may be reduced.

If the steering wheel is turned until it reaches the end of its travel, and is held in that position for an extended period of time, power steering assist may be reduced.

Normal use of the power steering assist should return when the system cools down.

See your dealer if there is a problem.

190 Driving and Operating

Caution

Do not hold the steering wheel at full rotation for more than

15 seconds and/or at an elevated

RPM. Damage may occur to the power steering system and there may be loss of power steering assist.

Holding both sides of the steering wheel allows you to turn

180 degrees without removing a hand.

Antilock Brake System (ABS) allows steering while braking.

Off-Road Recovery

Curve Tips

Take curves at a reasonable speed.

Reduce speed before entering a curve.

Maintain a reasonable steady speed through the curve.

Wait until the vehicle is out of the curve before accelerating gently into the straightaway.

Steering in Emergencies

There are some situations when steering around a problem may be more effective than braking.

The vehicle's right wheels can drop off the edge of a road onto the shoulder while driving. Follow these tips:

1. Ease off the accelerator and then, if there is nothing in the way, steer the vehicle so that it straddles the edge of the pavement.

2. Turn the steering wheel about one-eighth of a turn, until the right front tire contacts the pavement edge.

3. Turn the steering wheel to go straight down the roadway.

Loss of Control

Skidding

There are three types of skids that correspond to the vehicle's three control systems:

Braking Skid — wheels are not rolling.

Steering or Cornering Skid — too much speed or steering in a curve causes tires to slip and lose cornering force.

Acceleration Skid — too much throttle causes the driving wheels to spin.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not overdriving those conditions. But skids are always possible.

If the vehicle starts to slide, follow these suggestions:

Ease your foot off the accelerator pedal and steer the way you want the vehicle to go.

The vehicle may straighten out.

Be ready for a second skid if it occurs.

Slow down and adjust your driving according to weather conditions. Stopping distance can be longer and vehicle control can be affected when traction is reduced by water, snow, ice, gravel, or other material on the road. Learn to recognize warning clues — such as enough water, ice, or packed snow on the road to make a mirrored surface — and slow down when you have any doubt.

Try to avoid sudden steering, acceleration, or braking, including reducing vehicle speed by shifting to a lower gear. Any sudden changes could cause the tires to slide.

Remember: Antilock brakes help avoid only the braking skid.

Off-Road Driving

Four-wheel-drive vehicles can be used for off-road driving. Vehicles without four-wheel drive and vehicles not equipped with All

Terrain (AT) or On-Off Road (OOR) tires must not be driven off-road except on a level, solid surface. For contact information about the original equipment tires, see the warranty manual.

One of the best ways for successful off-road driving is to control the speed.

Driving and Operating 191

{

Warning

When driving off-road, bouncing and quick changes in direction can easily throw you out of position. This could cause you to lose control and crash. You and your passengers should always wear seat belts.

Before Driving Off-Road

Have all necessary maintenance and service work completed.

Fuel the vehicle, fill fluid levels, and check inflation pressure in all tires, including the spare, if equipped.

Read all the information about four-wheel-drive vehicles in this manual.

Remove any underbody air deflector, if equipped. Re-attach the air deflector after off-road driving.

Know the local laws that apply to off-road driving.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

192 Driving and Operating

To gain more ground clearance if needed, it may be necessary to remove the front fascia lower air dam, if equipped. However, driving without the air dam reduces fuel economy.

Caution

Operating the vehicle for extended periods without the front fascia lower air dam installed can cause improper airflow to the engine. Reattach the front fascia air dam after off-road driving.

Loading the Vehicle for

Off-Road Driving

{

Warning

Unsecured cargo on the load floor can be tossed about when driving over rough terrain. You or your

(Continued)

Warning (Continued)

passengers can be struck by flying objects. Secure the cargo properly.

Keep cargo in the cargo area as far forward and as low as possible. The heaviest things should be on the floor, forward of the rear axle.

Heavy loads on the roof raise the vehicle's center of gravity, making it more likely to roll over. You can be seriously or fatally injured if the vehicle rolls over. Put heavy loads inside the cargo area, not on the roof.

Driving on Hills

Driving safely on hills requires good judgment and an understanding of what the vehicle can and cannot do.

{

Warning

Many hills are simply too steep for any vehicle. Driving up hills can cause the vehicle to stall.

Driving down hills can cause loss of control. Driving across hills can

13337620) - 2020 - CRC - 4/11/19

Warning (Continued)

cause a rollover. You could be injured or killed. Do not drive on steep hills.

Before driving on a hill, assess the steepness, traction, and obstructions. If the terrain ahead cannot be seen, get out of the vehicle and walk the hill before driving further.

When driving on hills:

Use a low gear and keep a firm grip on the steering wheel.

Maintain a slow speed.

When possible, drive straight up or down the hill.

Slow down when approaching the top of the hill.

Use headlamps even during the day to make the vehicle more visible.

{

Warning

Driving to the top of a hill at high speed can cause a crash. There could be a drop-off, embankment, cliff, or even another vehicle. You could be seriously injured or killed. As you near the top of a hill, slow down and stay alert.

Never go downhill forward or backward with either the transmission or transfer case in

N (Neutral). The brakes could overheat and you could lose control.

{

Warning

If the vehicle has the two-speed automatic transfer case, shifting the transfer case to N (Neutral) can cause your vehicle to roll even if the transmission is in

P (Park). This is because the

N (Neutral) position on the

Driving and Operating 193

Warning (Continued)

transfer case overrides the transmission. You or someone else could be injured. If leaving the vehicle, set the parking brake and shift the transmission to

P (Park). Shift the transfer case to any position but N (Neutral).

When driving down a hill, keep the vehicle headed straight down. Use a low gear because the engine will work with the brakes to slow the vehicle and help keep the vehicle under control.

{

Warning

Heavy braking when going down a hill can cause your brakes to overheat and fade. This could cause loss of control and you or others could be injured or killed.

Apply the brakes lightly when

Warning (Continued)

descending a hill and use a low gear to keep vehicle speed under control.

If a brake fade condition is detected, a DIC warning message is displayed. Adjust brake pedal use and shift to a lower transmission gear to reduce braking.

If the brakes continue to fade to a severe condition, additional DIC messages are displayed. The brake system warning light will illuminate, and the vehicle speed may be limited. See

Brake System Warning

Light

140

If the vehicle stalls on a hill:

1. Apply the brakes to stop the vehicle, and then apply the parking brake.

2. Shift into P (Park) and then restart the engine.

If driving uphill when the vehicle stalls, shift to

R (Reverse), release the parking brake, and back straight down.

Never try to turn the vehicle around. If the hill is steep enough to stall the vehicle, it is steep enough to cause it to roll over.

If you cannot make it up the hill, back straight down the hill.

Never back down a hill in

N (Neutral) using only the brake. The vehicle can roll backward quickly and you could lose control.

If driving downhill when the vehicle stalls, shift to a lower gear, release the parking brake, and drive straight down the hill.

3. If the vehicle cannot be restarted after stalling, set the parking brake, shift into

P (Park), and turn the vehicle off.

3.1. Leave the vehicle and seek help.

3.2. Stay clear of the path the vehicle would take if it rolled downhill.

Avoid turns that take the vehicle across the incline of the hill.

A hill that can be driven straight up or down might be too steep to drive across. Driving across an incline puts more weight on the downhill wheels, which could cause a downhill slide or a rollover.

Surface conditions can be a problem. Loose gravel, muddy spots, or even wet grass can cause the tires to slip sideways, downhill. If the vehicle slips sideways, it can hit something that will trip it — a rock, a rut, etc.

— and roll over.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

Hidden obstacles can make the steepness of the incline more severe. If a rock is driven across with the uphill wheels, or if the downhill wheels drop into a rut or depression, the vehicle can tilt even more.

If an incline must be driven across, and the vehicle starts to slide, turn downhill. This should help straighten out the vehicle and prevent the side slipping.

{

Warning

Getting out of the vehicle on the downhill side when stopped across an incline is dangerous.

If the vehicle rolls over, you could be crushed or killed. Always get out on the uphill side of the vehicle and stay well clear of the rollover path.

Driving in Mud, Sand, Snow, or Ice

Use a low gear when driving in mud

— the deeper the mud, the lower the gear. Keep the vehicle moving to avoid getting stuck.

Traction changes when driving on sand. On loose sand, such as on beaches or sand dunes, the tires tend to sink into the sand. This affects steering, accelerating, and braking. Drive at a reduced speed and avoid sharp turns or abrupt maneuvers.

Traction is reduced on hard packed snow and ice and it is easy to lose control. Reduce vehicle speed when driving on hard packed snow and ice.

{

Warning

Driving on frozen lakes, ponds, or rivers can be dangerous. Ice conditions vary greatly and the vehicle could fall through the ice;

(Continued)

Warning (Continued)

you and your passengers could drown. Drive your vehicle on safe surfaces only.

Driving in Water

{

Warning

Driving through rushing water can be dangerous. Deep water can sweep your vehicle downstream and you and your passengers could drown. If it is only shallow water, it can still wash away the ground from under your tires.

Traction could be lost, and the vehicle could roll over. Do not drive through rushing water.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

196 Driving and Operating

Caution

Do not drive through standing water if it is deep enough to cover the wheel hubs, axles, or exhaust pipe. Deep water can damage the axle and other vehicle parts.

If the standing water is not too deep, drive through it slowly. At faster speeds, water can get into the engine and cause it to stall. Stalling can occur if the exhaust pipe is under water. Do not turn off the ignition when driving through water.

If the exhaust pipe is under water, the engine will not start. When going through water, the brakes get wet and it may take longer to stop. See

“ Driving on Wet Roads ” later in this section.

After Off-Road Driving

Remove any brush or debris that has collected on the underbody or chassis, or under the hood. These accumulations can be a fire hazard.

Re-install underbody air deflector and air dam if removed.

After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking.

Check the body structure, driveline, steering, suspension, wheels, tires, and exhaust system for damage and check the fuel lines and cooling system for any leakage.

More frequent maintenance service is required. See the

Maintenance

Schedule

441

Driving on Wet Roads

Rain and wet roads can reduce vehicle traction and affect your ability to stop and accelerate.

Always drive slower in these types of driving conditions and avoid driving through large puddles and deep-standing or flowing water.

{

Warning

Wet brakes can cause crashes.

They might not work as well in a quick stop and could cause pulling to one side. You could lose control of the vehicle.

After driving through a large puddle of water or a car/vehicle wash, lightly apply the brake pedal until the brakes work normally.

Flowing or rushing water creates strong forces. Driving through flowing water could cause the vehicle to be carried away. If this happens, you and other vehicle occupants could drown. Do not ignore police warnings and be very cautious about trying to drive through flowing water.

Hydroplaning

Hydroplaning is dangerous. Water can build up under the vehicle's tires so they actually ride on the water. This can happen if the road is

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19 wet enough and you are going fast enough. When the vehicle is hydroplaning, it has little or no contact with the road.

There is no hard and fast rule about hydroplaning. The best advice is to slow down when the road is wet.

Other Rainy Weather Tips

Besides slowing down, other wet weather driving tips include:

Allow extra following distance.

Pass with caution.

Keep windshield wiping equipment in good shape.

Keep the windshield washer fluid reservoir filled.

Have good tires with proper tread depth. See

Tires

379

Turn off cruise control.

Hill and Mountain Roads

Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips include:

Keep the vehicle serviced and in good shape.

Check all fluid levels and brakes, tires, cooling system, and transmission.

Shift to a lower gear when going down steep or long hills.

{

Warning

Using the brakes to slow the vehicle on a long downhill slope can cause brake overheating, can reduce brake performance, and could result in a loss of braking.

Shift the transmission to a lower gear to let the engine assist the brakes on a steep downhill slope.

{

Warning

Coasting downhill in N (Neutral) or with the ignition off is dangerous. This can cause overheating of the brakes and

Warning (Continued)

loss of steering assist. Always have the engine running and the vehicle in gear.

Drive at speeds that keep the vehicle in its own lane. Do not swing wide or cross the center line.

Be alert on top of hills; something could be in your lane

(e.g., stalled car, crash).

Pay attention to special road signs (e.g., falling rocks area, winding roads, long grades, passing or no-passing zones) and take appropriate action.

Winter Driving

Driving on Snow or Ice

Snow or ice between the tires and the road creates less traction or grip, so drive carefully. Wet ice can occur at about 0 °C (32 °F) when

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

198 Driving and Operating

freezing rain begins to fall. Avoid driving on wet ice or in freezing rain until roads can be treated.

For Slippery Road Driving:

Accelerate gently. Accelerating too quickly causes the wheels to spin and makes the surface under the tires slick.

Turn on Traction Control. See

Traction Control/Electronic

Stability Control

235

The Antilock Brake System

(ABS) improves vehicle stability during hard stops, but the brakes should be applied sooner than when on dry pavement.

See

Antilock Brake System

(ABS)

232

Allow greater following distance and watch for slippery spots. Icy patches can occur on otherwise clear roads in shaded areas.

The surface of a curve or an overpass can remain icy when the surrounding roads are clear.

Avoid sudden steering maneuvers and braking while on ice.

Turn off cruise control.

Blizzard Conditions

Stop the vehicle in a safe place and signal for help. Stay with the vehicle unless there is help nearby.

If possible, use Roadside

Assistance. See

Roadside

Assistance Program

465

. To get

help and keep everyone in the vehicle safe:

Turn on the hazard warning flashers.

Tie a red cloth to an outside mirror.

{

Warning

Snow can trap engine exhaust under the vehicle. This may cause exhaust gases to get inside. Engine exhaust contains carbon monoxide (CO), which cannot be seen or smelled. It can cause unconsciousness and even death.

(Continued)

Warning (Continued)

If the vehicle is stuck in snow:

Clear snow from the base of the vehicle, especially any blocking the exhaust pipe.

Open a window about 5 cm

(2 in) on the vehicle side that is away from the wind, to bring in fresh air.

Fully open the air outlets on or under the instrument panel.

Adjust the climate control system to circulate the air inside the vehicle and set the fan speed to the highest setting. See “ Climate

Control Systems.

”

For more information about CO, see

Engine Exhaust

220

To save fuel, run the engine for short periods to warm the vehicle and then shut the engine off and partially close the window. Moving about to keep warm also helps.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

If it takes time for help to arrive, when running the engine, push the accelerator pedal slightly so the engine runs faster than the idle speed. This keeps the battery charged to restart the vehicle and to signal for help with the headlamps.

Do this as little as possible, to save fuel.

If the Vehicle Is Stuck

Slowly and cautiously spin the wheels to free the vehicle when stuck in sand, mud, ice, or snow.

See “ Rocking the Vehicle to Get It

Out ” later in this section.

The Traction Control/Electronic

Stability Control can often help to free a stuck vehicle. See

. If TC/ESC cannot free the

vehicle, see “ Rocking the Vehicle to

Get it Out ” following.

{

Warning

If the vehicle's tires spin at high speed, they can explode, and you or others could be injured. The vehicle can overheat, causing an engine compartment fire or other damage. Spin the wheels as little as possible and avoid going above 56 km/h (35 mph).

For information about using tire chains on the vehicle, see

Rocking the Vehicle to Get

It Out

Caution

Do not hold the steering wheel at full rotation for more than

15 seconds and/or at an elevated

RPM. Damage may occur to the power steering system and there may be loss of power steering assist.

Driving and Operating 199

Turn the steering wheel left and right to clear the area around the front wheels. Then make sure the wheels are pointed straight ahead.

For four-wheel-drive vehicles, shift into Four-Wheel Drive High. Turn the TCS off. Shift back and forth between R (Reverse) and a forward gear, spinning the wheels as little as possible. To prevent transmission wear, wait until the wheels stop spinning before shifting gears.

Slowly spinning the wheels in the forward and reverse directions causes a rocking motion that could free the vehicle. If that does not get the vehicle out after a few tries, it might need to be towed out. See

Towing the Vehicle

424

. Recovery hooks can be used, if the vehicle has them.

Recovery Hooks

{

Warning

Never pull on recovery hooks from the side. The hooks could break and you and others could be injured. When using recovery hooks, always pull the vehicle from the front.

Caution

Never use recovery hooks to tow the vehicle. The vehicle could be damaged, and the repairs would not be covered by the vehicle warranty.

There are recovery hooks at the front of the vehicle. Use them if the vehicle is stuck off-road and needs to be pulled some place to continue driving.

Vehicle Load Limits

It is very important to know how much weight the vehicle can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo, and all nonfactory-installed options.

Two labels on the vehicle may show how much weight it was designed to carry: the Tire and

Loading Information label and the Certification/Tire label.

{

Warning

Do not load the vehicle any heavier than the Gross

Vehicle Weight Rating

(GVWR), or either the maximum front or rear Gross

Axle Weight Rating (GAWR).

This can cause systems to break and change the way the vehicle handles. This could cause loss of control and a crash. Overloading can also reduce stopping distance, damage the tires, and shorten the life of the vehicle.

Driving and Operating 201

Determine the combined weight of the driver and passengers that will be riding in your vehicle.

Subtract the combined weight of the driver and passengers from XXX kg or

XXX lbs.

The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the

"XXX" amount equals

1400 lbs. and there will be five 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs.

(1400-750 (5 x 150) =

650 lbs.)

Determine the combined weight of luggage and cargo being loaded on the vehicle.

Two-Tiered Loading

Depending on the model of the pickup, an upper load platform can be created by positioning three or four 5 cm (2 in) by

15 cm (6 in) wooden planks across the width of the pickup box. The planks must be inserted in the pickup box depressions.

When using this upper load platform, be sure the load is securely tied down to prevent it from shifting. The load's center of gravity should be positioned in a zone over the rear axle. The zone is located in the area between the front of each wheel well and the rear of each wheel

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19 well. The center of gravity height must not extend above the top of the pickup box flareboard.

Any load that extends beyond the vehicle's taillamp area must be properly marked according to local laws and regulations.

Remember not to exceed the

Gross Axle Weight

Rating (GAWR) of the front or rear axle.

Add-On Equipment

When carrying removable items, a limit on how many people carried inside the vehicle may be necessary. Be sure to weigh the vehicle before buying and installing the new equipment.

Truck-Camper Loading

Information

A vehicle-specific Truck-Camper

Loading Information label is attached to the inside of the vehicle's glove box. This label indicates if a slide-in camper can be carried, how much of a load the vehicle can carry, and how to correctly spread out the load. It will help to match the right slide-in camper to the vehicle.

Your dealer can help make a good vehicle-camper match and help determine the Cargo

Weight Rating (CWR).

When installing and loading a slide-in camper, check the manufacturer's instructions.

When carrying a slide-in camper, the total cargo load of the vehicle is the weight of the camper plus:

Everything added to the camper after it left the factory.

Everything in the camper.

All the people inside.

The CWR is the maximum weight of the load the vehicle can carry. It does not include the weight of the people inside. But, use about 68 kg (150 lb) for each seat.

The total cargo load must not be more than the vehicle's CWR.

Refer to the Truck-Camper

Loading Information label in the glove box for dimensions A and

B as shown in the following illustration.

Use the rear edge of the load floor for measurement purposes.

The recommended location for the cargo center of gravity is in zone C for the CWR. It is the point where the mass of a body is concentrated and, if suspended at that point, would balance the front and rear.

Here is an example of proper truck and camper match:

13337620) - 2020 - CRC - 4/11/19

Camper Center of

Gravity

Recommended Center of

Gravity Location Zone

When the truck is used to carry a slide-in camper, the total cargo load of the truck consists of the manufacturer's camper weight figure, the weight of installed additional camper equipment not included in the manufacturer's camper weight figure, the weight of camper cargo, and the weight of passengers in the camper.

The total cargo load should not exceed the truck's cargo weight rating, and the camper's center of gravity (1) should fall within the truck's recommended center of gravity zone (2) when installed.

Any accessories or other equipment that are added to the vehicle must be weighed. Then, subtract this extra weight from the CWR. This extra weight may shorten the center of gravity zone of the vehicle.

If the slide-in camper and its load weighs less than the CWR, the center of gravity zone for the vehicle may be larger.

Secure loose items to prevent weight shifts that could affect the balance of the vehicle. When the truck-camper is loaded, drive to a scale and weigh on the front and on the rear wheels separately to determine axle loads. Individual axle loads should not exceed either of the

Driving and Operating 207

(GAWR). The total axle loads should not exceed the vehicle's gross vehicle weight rating

(GVWR). These ratings are given on the Certification/

Tire label attached to the

Move the shift lever to P (Park) or

N (Neutral). To restart the engine when the vehicle is already moving, use N (Neutral) only.

Caution

Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission.

Shift to P (Park) only when the vehicle is stopped.

Starting Procedure

1. For Key Access vehicles, turn the ignition key to START.

When the engine starts, let go of the key.

For Keyless Access vehicles, the RKE transmitter must be in the vehicle. Press ENGINE

START/STOP with the brake pedal applied. When the engine begins cranking, let go of the button.

The idle speed will go down as the engine gets warm. Do not race the engine immediately after starting it. Operate the engine and transmission gently to allow the oil to warm up and lubricate all moving parts.

When the low fuel warning light is on and the FUEL LEVEL

LOW message is displayed in the Driver Information Center

(DIC), hold the ignition switch in the START position to continue engine cranking.

Caution

Cranking the engine for long periods of time, by returning the ignition to the START position immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to let the cranking motor cool down.

2. If the engine does not start after five to 10 seconds, especially in very cold weather

(below − 18 °C or 0 °F), it could be flooded with too much

Driving and Operating 213

gasoline. Try pushing the accelerator pedal all the way to the floor and holding it there while holding the key in START or ENGINE START/STOP for up to a maximum of

15 seconds. Wait at least

15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, let go of the key or button and accelerator. If the vehicle starts briefly but then stops again, do the same thing.

This clears the extra gasoline from the engine. Do not race the engine immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts.

Stop/Start System

If equipped, the Stop/Start system will shut off the engine to help conserve fuel. It has components designed for the increased number of starts.

Warning

It can be dangerous to leave the vehicle with the engine running.

The vehicle could move suddenly if the shift lever is not fully in

P (Park) with the parking brake firmly set.

If you have four-wheel drive and the transfer case is in N (Neutral), the vehicle will be free to roll, even if the shift lever is in

P (Park). So be sure the transfer case is in a drive gear – not in

N (Neutral).

And, if you leave the vehicle with the engine running, it could overheat and even catch fire. You or others could be injured. Do not leave the vehicle with the engine running unless you have to.

218 Driving and Operating

If you have to leave the vehicle with the engine running, be sure the vehicle is in P (Park) and the parking brake is firmly set before you leave it. After moving the shift lever into P (Park), hold the regular brake pedal down. Then, see if you can move the shift lever away from

P (Park) without first pulling it toward you. If you can, it means that the shift lever was not fully locked into

P (Park).

Torque Lock

If you are parking on a hill and you do not shift the transmission into

P (Park) properly, the weight of the vehicle may put too much force on the parking pawl in the transmission. You may find it difficult to pull the shift lever out of P (Park).

This is called torque lock. To prevent torque lock, set the parking brake and then shift into P (Park) properly before you leave the driver seat.

When you are ready to drive, move the shift lever out of P (Park) before you release the parking brake.

If torque lock does occur, you may need to have another vehicle push yours a little uphill to take some of the pressure from the parking pawl in the transmission. You will then be able to pull the shift lever out of

P (Park).

Shifting out of Park

This vehicle is equipped with an electronic shift lock release system.

The system is designed to prevent movement of the shift lever out of

P (Park), unless the brake pedal is applied and the ignition is on or in

Service Mode.

The shift lock release is always functional except in the case of an uncharged or low voltage – less than 9 volt – battery.

If the vehicle has an uncharged or low voltage battery, try charging or jump starting the battery. See

Jump

Starting - North America

To shift out of P (Park):

1. Apply the brake pedal.

2. Release the parking brake if it is applied. See

Electric Parking

Brake

233

3. Pull the shift lever toward you, then move it to the desired position, and release.

If the vehicle still cannot be shifted out of P (Park):

1. Ease the pressure on, or release the shift lever.

2. While holding the brake pedal, push the shift lever all the way into P (Park).

3. Pull the shift lever toward you, then move it to the desired position, and release.

If there is still a problem shifting, have the vehicle serviced soon.

Parking over Things

That Burn

{

Warning

Things that can burn could touch hot exhaust parts under the vehicle and ignite. Do not park over papers, leaves, dry grass, or other things that can burn.

Active Fuel Management

If equipped, Active Fuel

Management allows a V8, V6, or L4 gasoline engine to operate on either all of its cylinders, or a reduced number of cylinders, depending on the driving conditions.

When less power is required, such as cruising at a constant vehicle speed, the system will enable reduced cylinder operation, allowing the vehicle to achieve better fuel economy. When greater power is required, such as accelerating from a stop, passing, or merging onto a freeway, the system will maintain full-cylinder operation.

Dynamic Fuel Management

If equipped, Dynamic Fuel

Management calculates the number of cylinders needed to maximize fuel economy and meet the driving demands. Dynamic Fuel

Management allows the engine to operate in multiple possible configurations ranging from

1-cylinder up to the full 8-cylinder operation.

Extended Parking

It is best not to park with the vehicle running. If the vehicle is left running, be sure it will not move and there is adequate ventilation.

See

N (Neutral) only.

Also, use N (Neutral) when the vehicle is being towed.

{

Warning

Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is firmly on the brake pedal, the vehicle could move very rapidly.

You could lose control and hit people or objects. Do not shift into a drive gear while the engine is running at high speed.

Caution

Shifting out of P (Park) or

N (Neutral) with the engine running at high speed may damage the transmission. The repairs would not be covered by the vehicle warranty. Be sure the engine is not running at high speed when shifting the vehicle.

Caution

A transmission or engine oil hot message may display if the automatic transmission fluid or engine oil is too hot. Driving under this condition can damage the vehicle. Stop and idle the engine to cool the engine oil or automatic transmission fluid.

These messages will clear when the engine oil or transmission fluid has cooled sufficiently.

D :

This position is for normal driving. It provides the best fuel economy. If more power is needed for passing, press the accelerator pedal down.

When going less than about 55 km/h (35 mph), push the accelerator pedal about halfway down.

When going about 55 km/h (35 mph) or more, push the accelerator all the way down.

By doing this, the vehicle shifts down to the next gear and has more power.

Use D (Drive) and Tow/Haul Mode when towing a trailer, carrying a heavy load, driving on steep hills, or driving off-road. Shift the transmission to a lower gear if the transmission shifts too often.

Downshifting the transmission in slippery road conditions could result in skidding. See “ Skidding ” under

Loss of Control

190

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

The vehicle has a shift stabilization feature that adjusts the transmission shifting to the current driving conditions in order to reduce rapid upshifts and downshifts. This shift stabilization feature is designed to determine, before making an upshift, if the engine is able to maintain vehicle speed by analyzing things such as vehicle speed, throttle position, and vehicle load.

If the shift stabilization feature determines that a current vehicle speed cannot be maintained, the transmission does not upshift and instead holds the current gear.

In some cases, this could appear to be a delayed shift, however the transmission is operating normally.

If the engine or transmission detects an impending hot fluid condition, the transmission may upshift to limit temperatures. Downshifts may also be prevented. Normal operation may continue unless the display indicates there is a hot condition and engine should be idled.

The transmission uses adaptive shift controls. The adaptive shift control process continually compares key shift parameters to pre-programmed ideal shifts stored in the transmission ’ s computer. The transmission constantly makes adjustments to improve vehicle performance according to how the vehicle is being used, such as with a heavy load or when the temperature changes. During this adaptive shift control process, shifting might feel different as the transmission determines the best settings.

When temperatures are very cold, the transmission's gear shifting could be delayed providing more stable shifts until the engine warms up. Shifts could be more noticeable with a cold transmission. This difference in shifting is normal.

If equipped with the 2.7L L4 engine, engine speeds may be increased while driving at highway speeds while the engine is still warming up.

224 Driving and Operating

Manual Mode

Range Selection Mode

Range Selection Mode helps control the vehicle's transmission and vehicle speed while driving downhill or towing a trailer by letting you select a desired range of gears.

To use this feature:

1. Move the shift lever to

L (Manual Mode).

2. Press the plus/minus buttons on the shift lever to select the desired range of gears for current driving conditions.

When the shift lever is moved from

D (Drive) to L (Manual Mode), a number displays next to the L, indicating the current transmission range.

This number is the highest gear that the transmission will command while operating in L (Manual Mode). All gears below that number are available. As driving conditions change, the transmission can automatically shift to lower gears.

For example, when L5 is selected,

1 (First) through 5 (Fifth) gears are automatically shifted by the transmission, but 6 (Sixth) cannot be used until the plus/minus button on the shift lever is used to change to the range.

When the shift lever is moved from

D (Drive) to L (Manual Mode), a downshift may occur. The gear that the transmission is operating in when the shift lever is moved from

D (Drive) to L (Manual Mode) determines if a downshift occurs.

See the following charts.

Brakes

Electric Brake Boost

Vehicles equipped with electric brake boost have hydraulic brake circuits that are electronically controlled when the brake pedal is applied during normal operation.

The system performs routine tests and turns off within a few minutes after the vehicle is shutdown. Noise may be heard during this time. If the brake pedal is pressed during the tests or when the electric brake boost system is off, a noticeable change in pedal force and travel may be felt. This is normal.

Antilock Brake

System (ABS)

The Antilock Brake System (ABS) helps prevent a braking skid and maintain steering while braking hard.

ABS performs a system check when the vehicle is first driven.

A momentary motor or clicking noise

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19 may be heard while this test is going on, and the brake pedal may move slightly. This is normal.

If there is a problem with ABS, this warning light stays on. See

Antilock

Brake System (ABS) Warning Light

141

ABS does not change the time needed to get a foot on the brake pedal and does not always decrease stopping distance. If you get too close to the vehicle ahead, there will not be enough time to apply the brakes if that vehicle suddenly slows or stops. Always leave enough room ahead to stop, even with ABS.

Using ABS

Do not pump the brakes. Just hold the brake pedal down firmly.

Hearing or feeling ABS operate is normal.

Braking in Emergencies

ABS allows steering and braking at the same time. In many emergencies, steering can help even more than braking.

Electric Parking Brake

The vehicle has an Electric Parking

Brake (EPB). The EPB can always be activated, even if the ignition is

If the EPB is applied while the vehicle is moving, the vehicle will decelerate as long as the switch is pressed. If the switch is pressed until the vehicle comes to a stop, the EPB will remain applied.

The vehicle may automatically apply the EPB in some situations when the vehicle is not moving. This is normal, and is done to periodically check the correct operation of the

EPB system.

If the EPB fails to apply, block the rear wheels to prevent vehicle movement.

EPB Release

To release the EPB:

1. Turn the ignition on or to ACC/

ACCESSORY.

2. Apply and hold the brake pedal.

3. Press the EPB switch momentarily.

The EPB is released when the or PARK light is off.

If the

8 light is on, release the EPB by pressing and holding the EPB switch. Continue to hold the switch until the

Y or PARK light is off.

If either light stays on after release is attempted, see your dealer.

Caution

Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts.

Make sure that the parking brake is fully released and the brake warning light is off before driving.

Automatic EPB Release

The EPB will automatically release if the vehicle is running, placed into gear, and an attempt is made to drive away. Avoid rapid acceleration when the EPB is applied, to preserve parking brake lining life.

Brake Assist

Brake Assist detects rapid brake pedal applications due to emergency braking situations and provides additional braking to activate the Antilock Brake System

(ABS) if the brake pedal is not pushed hard enough to activate

ABS normally. Minor noise, brake

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19 pedal pulsation, and/or pedal movement during this time may occur. Continue to apply the brake pedal as the driving situation dictates. Brake Assist disengages when the brake pedal is released.

Hill Start Assist (HSA)

{

Warning

Do not rely on the HSA feature.

HSA does not replace the need to pay attention and drive safely.

You may not hear or feel alerts or warnings provided by this system.

Failure to use proper care when driving may result in injury, death, or vehicle damage. See

Defensive Driving

187

When the vehicle is stopped on a grade, Hill Start Assist (HSA) prevents the vehicle from rolling in an unintended direction during the transition from brake pedal release to accelerator pedal apply. The brakes release when the accelerator pedal is applied. If the accelerator pedal is not applied within a few minutes, the Electric Parking Brake will apply. The brakes may also release under other conditions. Do not rely on HSA to hold the vehicle.

HSA is available when the vehicle is facing uphill in a forward gear, or when facing downhill in

R (Reverse). The vehicle must come to a complete stop on a grade for HSA to activate.

Traction Control/

Electronic Stability

Control

System Operation

The vehicle has a Traction Control

System (TCS) and StabiliTrak/

Electronic Stability Control (ESC) system. These systems help limit wheel spin and assist the driver in maintaining control, especially on slippery road conditions.

TCS activates if it senses any of the drive wheels are spinning or beginning to lose traction. When this happens, TCS applies the brakes to the spinning wheels and reduces engine power to limit wheel spin.

StabiliTrak/ESC activates when the vehicle senses a difference between the intended path and the direction the vehicle is actually traveling.

StabiliTrak/ESC selectively applies braking pressure to any one of the vehicle wheel brakes to assist the driver in keeping the vehicle on the

When the transfer case (if equipped) is in Four-Wheel Drive Low, the stability system is automatically disabled, g comes on, and the appropriate message will appear on the Driver Information Center (DIC).

Both traction control and StabiliTrak/

ESC are automatically disabled in this condition.

The indicator light for both systems is in the instrument cluster. This light will:

Flash when TCS is limiting wheel spin.

Flash when StabiliTrak/ESC is activated.

Turn on and stay on when either system is not working.

If either system fails to turn on or to activate, a message displays in the

Driver Information Center (DIC), and d comes on and stays on to indicate that the system is inactive and is not assisting the driver in maintaining control. The vehicle is safe to drive, but driving should be adjusted accordingly.

Cruise Control

{

Warning

Cruise control can be dangerous where you cannot drive safely at a steady speed. Do not use cruise control on winding roads or in heavy traffic.

Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads.

If equipped with cruise control, a speed of about 40 km/h (25 mph) or more can be maintained without keeping your foot on the accelerator. Cruise control does not work at speeds below about

40 km/h (25 mph).

If the cruise control is being used and the Traction Control System

(TCS) or StabiliTrak/Electronic

Stability Control (ESC) begins to limit wheel spin, the cruise control

Adaptive Cruise Control

(1500 Series)

If equipped, Adaptive Cruise Control

(ACC) allows the cruise control set speed and following gap to be selected. Read this entire section before using this system. The following gap is the following time between your vehicle and a vehicle detected directly ahead in your path, moving in the same direction. If no vehicle is detected in your path,

ACC works like regular cruise control. ACC uses a windshield mounted front camera sensor.

If a vehicle is detected in your path,

ACC can apply acceleration or limited, moderate braking to maintain the selected following gap.

To disengage ACC, apply the brake.

If ACC is controlling the vehicle speed when the Traction Control

System (TCS) or StabiliTrak/

Electronic Stability Control (ESC) system activates, ACC may automatically disengage. See

Traction Control/Electronic Stability

Control

235

. When road

conditions allow ACC to be safely used, ACC can be turned back on.

Disabling the TCS or StabiliTrak/

ESC system will disengage and prevent engagement of ACC.

ACC can reduce the need for you to frequently brake and accelerate, especially when used on expressways, freeways, and interstate highways. When used on other roads, you may need to take over the control of braking or acceleration more often.

{

Warning

ACC has limited braking ability and may not have time to slow the vehicle down enough to avoid a collision with another vehicle you are following. This can occur when vehicles suddenly slow or stop ahead, or enter your lane.

Also see “ Alerting the Driver ” later in this section. Complete attention is always required while driving and you should be ready to take action and apply the brakes. See

Defensive Driving

187

{

Warning

ACC will not detect or brake for children, pedestrians, animals, or other objects.

Do not use ACC when:

On winding and hilly roads or when the camera sensor is blocked by snow, ice, or dirt. The system may not detect a vehicle ahead.

Keep the windshield and headlamps clean.

When visibility is poor due to rain, snow, fog, dirt, insect residue, or dust; when other foreign objects obscure the camera ’ s view; or when the vehicle in front or oncoming traffic causes additional environmental obstructions, such as road spray. ACC performance is limited under these conditions.

Approaching and Following a

Vehicle

The vehicle ahead indicator is in the instrument cluster. It only displays when a vehicle is detected in your vehicle ’ s path moving in the same direction. If this symbol is not displaying, ACC will not respond to or brake for vehicles ahead.

ACC automatically slows the vehicle down and adjusts vehicle speed to follow a detected vehicle ahead at the selected following gap. The vehicle speed increases or decreases to follow a detected vehicle in front of your vehicle when that vehicle is traveling slower than your vehicle set speed. It may apply limited braking, if necessary. When braking is active, the brake lamps will come on. The automatic braking may feel or sound different than if the brakes were applied manually.

This is normal.

Stationary or Very Slow-Moving

Objects

{

Warning

ACC may not detect and react to stopped or slow-moving vehicles ahead of you. For example, the system may not brake for a vehicle it has never detected moving. This can occur in stop-and-go traffic or when a vehicle suddenly appears due to a vehicle ahead changing lanes.

Your vehicle may not stop and could cause a crash. Use caution when using ACC. Your complete attention is always required while driving and you should be ready to take action and apply the brakes.

Irregular Objects Affecting ACC

ACC may have difficulty detecting the following objects:

Erasing Speed Memory

The ACC set speed is erased from memory if

J is pressed or if the ignition is turned off.

Weather Conditions Affecting ACC

If the interior temperature is extremely high, the instrument cluster may indicate that ACC is temporarily unavailable. This can be caused by extreme hot weather conditions with direct sunlight on the front camera. ACC will return to normal operation once the cabin temperature is lower.

Conditions that are associated with low visibility, such as fog, rain, snow, or road spray, may limit ACC performance. Water droplets from rain or snow that remain on the windshield may also limit ACC ’ s ability to detect objects.

Lighting Conditions Affecting ACC

The ACC front camera can be affected by poor lighting conditions, and ACC may have limited performance when:

There are changes in brightness, such as entering and exiting tunnels, bridges, and overpasses.

Low sun angles cause the camera to not detect objects, or it is more difficult to detect objects in the same traffic lane.

Lighting is poor in the evening or early morning

There are multiple changes in brightness or shadows along the vehicle roadway.

In a tunnel without the headlamps on, or in a tunnel when there is a vehicle in front that does not have its taillamps on.

Park Assist

With Front and Rear Park Assist, as the vehicle moves at speeds of less than 8 km/h (5 mph) the sensors on the bumpers may detect objects up to 1.2 m (4 ft) in front and 2.5 m (8 ft) behind the vehicle within a zone

25 cm (10 in) high off the ground and below bumper level. These detection distances may be shorter during warmer or humid weather.

Blocked sensors will not detect objects and can also cause false detections. Keep the sensors clean of mud, dirt, snow, ice, and slush; and clean sensors after a car wash in freezing temperatures.

{

Warning

The Park Assist system does not detect children, pedestrians, bicyclists, animals, or objects located below the bumper or that are too close or too far from the vehicle. It is not available at speeds greater than 8 km/h

(5 mph). To prevent injury, death, or vehicle damage, even with

Park Assist, always check the area around the vehicle and check all mirrors before moving forward or backing.

The instrument cluster may have a

Park Assist display with bars that show “ distance to object ” and object

Driving and Operating 267

location information for the Front and Rear Park Assist system. As the object gets closer, more bars light up and the bars change color from yellow to amber to red.

When an object is first detected in the rear, one beep will be heard from the rear, or both sides of the

Safety Alert Seat will pulse two times. When an object is very close

— <0.4 m (1.5 ft) in the vehicle rear or <0.3 m (1 ft) in the vehicle front — a continuous beep will sound from the rear or front depending on object location, or both sides of the

Safety Alert Seat will pulse five times. Beeps for FPA are higher pitched than for RPA.

Rear Cross Traffic Alert (RCTA)

If equipped, when the vehicle is shifted into R (Reverse), RCTA shows a red warning triangle with a left or right pointing arrow on the infotainment display to warn of traffic coming from the left or right.

This system detects objects coming from up to 20 m (65 ft) from the left or right side of the vehicle. When an object is detected, either three

Cleaning the System

If the FCA system does not seem to operate properly, this may correct the issue:

Clean the outside of the windshield in front of the rearview mirror.

Clean the entire front of the vehicle.

Clean the headlamps.

Automatic Emergency

Braking (AEB)

If the vehicle has Forward Collision

Alert (FCA), it also has AEB (1500 series only), which includes

Intelligent Brake Assist (IBA). When the system detects a vehicle ahead in your path that is traveling in the same direction that you may be about to crash into, it can provide a boost to braking or automatically brake the vehicle. This can help avoid or lessen the severity of crashes when driving in a forward gear. Depending on the situation, the vehicle may automatically brake moderately or hard. This automatic emergency braking can only occur if a vehicle is detected. This is shown by the FCA vehicle ahead indicator being lit. See

Forward Collision Alert

(FCA) System

268

The system works when driving in a forward gear between 8 km/h

(5 mph) and 80 km/h (50 mph).

It can detect vehicles up to approximately 60 m (197 ft).

{

Warning

AEB is an emergency crash preparation feature and is not designed to avoid crashes. Do not rely on AEB to brake the vehicle. AEB will not brake outside of its operating speed range and only responds to detected vehicles.

AEB may not:

(1500 Series)

If equipped, the LCA system is a lane-changing aid that assists drivers with avoiding lane change crashes that occur with moving vehicles in the side blind zone (or spot) areas or with vehicles rapidly approaching these areas from behind. The LCA warning display will light up in the corresponding outside side mirror and will flash if the turn signal is on.

{

Warning

LCA does not alert the driver to vehicles outside of the system detection zones, pedestrians,

Warning (Continued)

bicyclists, or animals. It may not provide alerts when changing lanes under all driving conditions.

Failure to use proper care when changing lanes may result in injury, death, or vehicle damage.

Before making a lane change, always check mirrors, glance over your shoulder, and use the turn signals.

LCA Detection Zones

Driving and Operating 275

The LCA sensor covers a zone of approximately one lane over from both sides of the vehicle, or 3.5 m

(11 ft). The height of the zone is approximately between 0.5 m (1.5 ft) and 2 m (6 ft) off the ground. The

Side Blind Zone Alert (SBZA) warning area starts at approximately the middle of the vehicle and goes back 5 m (16 ft). Drivers are also warned of vehicles rapidly approaching from up to 25 m (82 ft) behind the vehicle.

How the System Works

The LCA symbol lights up in the side mirrors when the system detects a moving vehicle in the next lane over that is in the side blind zone or rapidly approaching that zone from behind. A lit LCA symbol indicates it may be unsafe to change lanes. Before making a lane change, check the LCA display, check mirrors, glance over your shoulder, and use the turn signals.

Display

When the vehicle is started, both outside mirror LCA displays will briefly come on to indicate the system is operating. When the vehicle is in a forward gear, the left or right side mirror display will light up if a moving vehicle is detected in the next lane over in that blind zone or rapidly approaching that zone.

If the turn signal is activated in the same direction as a detected vehicle, this display will flash as an extra warning not to change lanes.

LCA is disabled when the trailer connection status is displayed.

A DIC message may display. The

SBZA system still operates.

LCA can be disabled through vehicle personalization. When you disable LCA, SBZA is also disabled.

See

Vehicle Personalization

156

If LCA is disabled by the driver, the

LCA mirror displays will not light up.

When the System Does Not

Seem to Work Properly

The LCA system requires some driving for the system to calibrate to maximum performance. This calibration may occur more quickly if the vehicle is driving on a straight highway road with traffic and roadside objects (e.g., guardrails, barriers).

LCA displays may not come on when passing a vehicle quickly, for a stopped vehicle, or when towing a trailer. The LCA detection zones that extend back from the side of the vehicle do not move further back when a trailer is towed. Use caution while changing lanes when towing a trailer. LCA may alert to objects attached to the vehicle, such as a trailer, bicycle, or object extending out to either side of the vehicle.

Attached objects may also interfere with the detection of vehicles. This is normal system operation; the vehicle does not need service.

LCA may not always alert the driver to vehicles in the next lane over, especially in wet conditions or when driving on sharp curves. The system does not need to be serviced. The system may light up due to guardrails, signs, trees, shrubs, and other non-moving objects. This is normal system operation; the vehicle does not need service.

LCA may not operate when the LCA sensors in the left or right corners of the rear bumper are covered with mud, dirt, snow, ice, or slush, or in heavy rainstorms. For cleaning instructions, see "Washing the

Vehicle" under

Exterior Care

429

If the DIC still displays the system unavailable message after cleaning both sides of the vehicle toward the rear corners of the vehicle, see your dealer.

If the LCA displays do not light up when moving vehicles are in the side blind zone or are rapidly approaching this zone and the

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

Lane Departure Warning

(LDW) (2500/3500 Series)

If equipped, LDW may help avoid crashes due to unintentional lane departures. LDW uses a camera sensor to detect the lane markings at speeds of 56 km/h (35 mph) or greater. It may provide an alert if the vehicle is crossing a lane without using a turn signal in that direction.

LDW light will not alert if the turn signal is active in the direction of lane departure, or if LDW detects that you are accelerating, braking or actively steering.

{

Warning

The LDW system does not steer the vehicle. The LDW system may not:

Provide enough time to avoid a crash.

Detect lane markings under poor weather or visibility conditions. This can occur if the windshield or headlamps are blocked by dirt, snow, or ice; if they are not in proper condition; or if the sun shines directly into the camera.

Detect road edges.

Detect lanes on winding or hilly roads.

If LDW only detects lane markings on one side of the road, it will only warn you when departing the lane on the side where it has detected a lane marking. Always keep your

(Continued)

Driving and Operating 277

Warning (Continued)

attention on the road and maintain proper vehicle position within the lane, or vehicle damage, injury, or death could occur. Always keep the windshield, headlamps, and camera sensors clean and in good repair. Do not use LDW in bad weather conditions.

How the System Works

LDW utilizes camera sensor installed on the windshield ahead of the rearview mirror to detect lane markings.

To turn LDW on and off, press

@ on the instrument panel to the left of the steering wheel. The control indicator will light when LDW is on.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

278 Driving and Operating

When LDW is on,

@ is green if

LDW is available to warn of a lane departure. If the vehicle crosses a detected lane marking without using the turn signal in that direction, changes to amber and flashes.

Additionally, there will be three beeps, on the right or left, depending on the lane departure

@ direction. LDW will not alert if the turn signal is active in the direction of lane departure or if LDA detects that you are accelerating, braking or actively steering.

When the System Does Not

Seem to Work Properly

The system may not detect lanes as well when there are:

Close vehicles ahead.

Sudden lighting changes, such as when driving through tunnels.

Banked roads.

If the LDW system is not functioning properly when lane markings are clearly visible, cleaning the windshield may help.

LDW alerts may occur due to tar marks, shadows, cracks in the road, temporary or construction lane markings, or other road imperfections. This is normal system operation; the vehicle does not need service. Turn LDW off if these conditions continue.

Lane Keep Assist (LKA)

(1500 Series)

If equipped, LKA may help avoid crashes due to unintentional lane departures. This system uses a camera to detect lane markings between 60 km/h (37 mph) and 180 km/h (112 mph). It may assist by gently turning the steering wheel if the vehicle approaches a detected lane marking. It may also provide a

Lane Departure Warning (LDW) alert if the vehicle crosses a detected lane marking. LKA can be overriden by turning the steering wheel. This system is not intended to keep the vehicle centered in the lane. LKA will not assist and alert if the turn signal is active in the direction of lane departure, or if it detects that you are accelerating, braking or actively steering.

{

Warning

The LKA system does not continuously steer the vehicle.

It may not keep the vehicle in the lane or give a Lane Departure

Warning (LDW) alert, even if a lane marking is detected.

The LKA and LDW systems may not:

Provide an alert or enough steering assist to avoid a lane departure or crash.

Detect lane markings under poor weather or visibility conditions. This can occur if the windshield or headlamps are blocked by

Detect road edges.

Detect lanes on winding or hilly roads.

If LKA only detects lane markings on one side of the road, it will only assist or provide an LDW alert when approaching the lane on the side where it has detected a lane marking. Even with LKA and LDW, you must steer the vehicle. Always keep your attention on the road and maintain proper vehicle position within the lane, or vehicle damage, injury, or death could occur. Always keep the windshield, headlamps, and camera sensors clean and in good repair. Do not use LKA in

Warning (Continued)

bad weather conditions or on roads with unclear lane markings, such as construction zones.

{

Warning

Using LKA while towing a trailer or on slippery roads could cause loss of control of the vehicle and a crash. Turn the system off.

How the System Works

LKA uses a camera sensor installed on the windshield ahead of the rearview mirror to detect lane markings. It may provide brief steering assist if it detects an unintended lane departure. It may further provide an audible alert or the driver seat may pulse indicating that a lane marking has been crossed.

Driving and Operating 279

To turn LKA on and off, press

A on the center stack. If equipped, the indicator light on the button comes on when LKA is on and turns off when LKA is disabled.

When on,

A is white, if equipped, indicating that the system is not ready to assist.

A is green if LKA is ready to assist. LKA may assist by gently turning the steering wheel if the vehicle approaches a detected lane marking.

A is amber when assisting. It may also provide a

Lane Departure Warning (LDW) alert by flashing

A amber if the vehicle crosses a detected lane marking. Additionally, there may be three beeps, or the driver seat may pulse three times, on the right or left, depending on the lane departure direction.

Take Steering

The LKA system does not continuously steer the vehicle.

If LKA does not detect active driver steering, an alert and chime may be provided. Steer the vehicle to

dismiss. LKA may become temporarily unavailable after repeated take steering alerts.

When the System Does Not

Seem to Work Properly

The system performance may be affected by:

Close vehicles ahead.

Sudden lighting changes, such as when driving through tunnels.

Banked roads.

Roads with poor lane markings, such as two-lane roads.

A system unavailable message may display if the camera is blocked.

The LKA system does not need service.

A camera blocked message may display if the camera is blocked.

Some driver assistance systems may have reduced performance or not work at all. An LKA or LDW unavailable message may display if the systems are temporarily unavailable. This message could be due to a blocked camera. The LKA system does not need service.

Clean the outside of the windshield behind the rearview mirror.

LKA assistance and/or LDW alerts may occur due to tar marks, shadows, cracks in the road, temporary or construction lane markings, or other road imperfections. This is normal system operation; the vehicle does not need service. Turn LKA off if these conditions continue.

Pull a trailer only if all the steps in this section have been followed.

Ask your dealer for advice and information about towing a trailer with the vehicle.

Driving with a Trailer

Trailering is different than just driving the vehicle by itself.

Trailering means changes in handling, acceleration, braking, durability, and fuel economy.

Successful, safe trailering takes correct equipment, and it has to be used properly.

The following information has many time-tested, important trailering tips and safety rules. Many of these are

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

288 Driving and Operating

important for your safety and that of your passengers. Read this section carefully before pulling a trailer.

When towing a trailer:

Become familiar with and follow all state and local laws that apply to trailer towing. These requirements vary from state to state.

State laws may require the use of extended side view mirrors.

Even if not required, you should install extended side view mirrors if your visibility is limited or restricted while towing.

Do not tow a trailer during the first 800 km (500 mi) of vehicle use to prevent damage to the engine, axle, or other parts.

It is recommended to perform the first oil change before heavy towing.

During the first 800 km (500 mi) of trailer towing, do not drive over 80 km/h (50 mph) and do not make starts at full throttle.

Vehicles can tow in D (Drive).

Tow/Haul Mode is recommended for heavier trailers. See

Tow/

Towing a trailer requires experience.

The combination of the vehicle and trailer is longer and not as responsive as the vehicle itself. Get used to the handling and braking of the combination by driving on a level road surface before driving on public roads.

The trailer structure, the tires, and the brakes must all be rated to carry the intended cargo. Inadequate trailer equipment can cause the combination to operate in an unexpected or unsafe manner.

Before driving, inspect all trailer hitch parts and attachments, safety chains, electrical connectors, lamps, tires, and mirrors. See

Towing

Equipment

297

. If the trailer has

electric brakes, start the combination moving and then manually apply the trailer brake controller to check that the trailer brakes work. During the trip, occasionally check that the cargo and trailer are secure and that the lamps and any trailer brakes are working.

Towing with a Stability Control

System

When towing, the stability control system might be heard. The system reacts to vehicle movement caused by the trailer, which mainly occurs during cornering. This is normal when towing heavier trailers.

Driving and Operating 289

Following Distance

Stay at least twice as far behind the vehicle ahead as you would when driving without a trailer. This can help to avoid heavy braking and sudden turns.

Passing

More passing distance is needed when towing a trailer. The combination of the vehicle and trailer will not accelerate as quickly and is much longer than the vehicle alone. It is necessary to go much farther beyond the passed vehicle before returning to the lane. Pass on level roadways. Avoid passing on hills if possible.

Backing Up

Hold the bottom of the steering wheel with one hand. To move the trailer to the left, move that hand to the left. To move the trailer to the right, move that hand to the right.

Always back up slowly and, if possible, have someone guide you.

13337620) - 2020 - CRC - 4/11/19

290 Driving and Operating

Making Turns

Caution

Turn more slowly and make wider arcs when towing a trailer to prevent damage to your vehicle.

Making very sharp turns could cause the trailer to contact the vehicle.

Make wider turns than normal when towing, so the trailer will not go over soft shoulders, over curbs, or strike road signs, trees, or other objects.

Always signal turns well in advance.

Do not steer or brake suddenly.

Driving on Grades

Reduce speed and shift to a lower gear before starting down a long or steep downhill grade. If the transmission is not shifted down, the brakes may overheat and result in reduced braking efficiency.

The vehicle can tow in D (Drive).

Shift the transmission to a lower gear if the transmission shifts too often under heavy loads and/or hilly conditions.

When towing at higher altitudes, engine coolant will boil at a lower temperature than at lower altitudes.

If the engine is turned off immediately after towing at high altitude on steep uphill grades, the vehicle could show signs similar to engine overheating. To avoid this, let the engine run, preferably on level ground, with the transmission in P (Park) for a few minutes before turning the engine off. If the overheat warning comes on, see

Engine Overheating

Parking on Hills

{

Warning

To prevent serious injury or death, always park your vehicle and trailer on a level surface when possible.

When parking your vehicle and your trailer on a hill:

1. Press the brake pedal, but do not shift into P (Park) yet. Turn the wheels into the curb if facing downhill or into traffic if facing uphill.

2. Have someone place chocks under the trailer wheels.

3. Gradually release the brake pedal to allow the chocks to absorb the load of the trailer.

4. Reapply the brake pedal. Then apply the parking brake and shift into P (Park).

provide a means of escape in the unlikely event the vehicle slides into the water.

If the boat launch surface is slippery, have the driver remain in the vehicle with the brake pedal applied while the boat is being launched. The boat launch can be especially slippery at low tide when part of the ramp was previously submerged at high tide. Do not back onto the ramp to launch the boat if you are not sure the vehicle can maintain traction.

Do not move the vehicle if someone is in the path of the trailer. Some parts of the trailer might be underwater and not visible to people who are assisting in launching the boat.

Driving and Operating 291

Disconnect the wiring to the trailer before backing the trailer into the water to prevent damage to the electrical circuits on the trailer.

Reconnect the wiring to the trailer after removing the trailer from the water. If the trailer has electric brakes that can function when the trailer is submerged, it might help to leave the electrical trailer connector attached to maintain trailer brake functionality while on the boat ramp.

To back the trailer into the water:

1. If equipped, place the vehicle in four-wheel-drive high.

2. Slowly back down the boat ramp until the boat is floating, but no further than necessary.

3. Press and hold the brake pedal, but do not shift into

P (Park) yet.

4. Have someone place chocks under the front wheels of the vehicle.

. It is especially important to check the engine oil, axle lubricant, belts, cooling system, and brake system before and during each trip.

Check periodically to see that all nuts and bolts on the trailer hitch are tight.

Engine Cooling When Trailer

Towing

The cooling system may temporarily overheat during severe operating conditions. See

Engine Overheating

351

Trailer Towing

If equipped with a diesel engine, see the Duramax diesel supplement.

Caution

Towing a trailer improperly can damage the vehicle and result in costly repairs not covered by the vehicle warranty. To tow a trailer correctly, follow the directions in this section and see your dealer for important information about towing a trailer with the vehicle.

Trailering is different than just driving the vehicle by itself.

Trailering means changes in handling, acceleration, braking, durability, and fuel economy.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

Successful, safe trailering takes correct equipment, and it has to be used properly.

The following information has many time-tested, important trailering tips and safety rules. Many of these are important for your safety and that of your passengers. Read this section carefully before pulling a trailer.

Trailer Weight

{

Warning

Never exceed the towing capacity for your vehicle.

Safe trailering requires monitoring the weight, speed, altitude, road grades, outside temperature, and how frequently the vehicle is used to tow a trailer.

Trailer Weight Ratings

When towing a trailer, the combined weight of the vehicle, vehicle contents, trailer, and trailer contents must be below all of the maximum weight ratings for the vehicle, including:

GCWR: Gross Combined Weight

Rating

GVWR: Gross Vehicle Weight

Rating

Maximum Trailer Weight Rating

GAWR-RR: Gross Axle Weight

Rating-Rear

Maximum Trailer Tongue Weight

Rating

See “ Weight-Distributing Hitch and

Adjustment ” under

Towing

Equipment

297

to determine if equalizer bars are required to obtain the maximum trailer weight rating.

See “ Trailer Brakes ” under

Towing

Equipment

297

to determine if brakes are required based on your trailer's weight.

The only way to be sure the weight is not exceeding any of these ratings is to weigh the tow vehicle and trailer combination, fully loaded for the trip, getting individual weights for each of these items.

Driving and Operating 293

A trailering information label on the

B-pillar shows tow rating information for the vehicle.

{

Warning

You and others could be seriously injured or killed if the trailer is too heavy or the trailer brakes are inadequate for the load. The vehicle may be damaged, and the repairs would not be covered by the vehicle warranty.

Only tow a trailer if all the steps in this section have been followed.

Ask your dealer for advice and information about towing a trailer.

Gross Combined Weight

Rating (GCWR)

GCWR is the total allowable weight of the completely loaded vehicle and trailer including any fuel, passengers, cargo, equipment, and accessories. Do not exceed the

GCWR for your vehicle. The GCWR for the vehicle is on the Trailering

Information Label.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

294 Driving and Operating

To check that the weight of the vehicle and trailer are within the

GCWR for the vehicle, follow these steps:

1. Start with the "curb weight" from the Trailering Information

Label.

2. Add the weight of the trailer loaded with cargo and ready for the trip.

3. Add the weight of all passengers.

4. Add the weight of all cargo in the vehicle.

5. Add the weight of hitch hardware such as a draw bar, ball, load equalizer bars, or sway bars.

6. Add the weight of any accessories or aftermarket equipment added to the vehicle.

The resulting weight cannot exceed the GCWR value on the Trailering

Information Label.

The gross combined weight can also be confirmed by weighing the truck and trailer on a public scale.

The truck and trailer should be loaded for the trip with passengers and cargo.

Gross Vehicle Weight

Rating (GVWR)

For information about the vehicle's maximum load capacity, see

Vehicle

Load Limits

200

. When calculating the GVWR with a trailer attached, the trailer tongue weight must be included as part of the weight the vehicle is carrying.

Maximum Trailer Weight

The maximum trailer weight rating is calculated assuming the tow vehicle has a driver, a front seat passenger, and all required trailering equipment. This value represents the heaviest trailer the vehicle can tow, but it may be necessary to reduce the trailer weight to stay within the GCWR, GVWR, maximum trailer tongue load, or GAWR-RR for the vehicle.

Use the Tow Rating Guide

(my.chevrolet.com/learn) to determine how much the trailer can weigh, based on the vehicle model and options.

Weights listed apply for conventional trailers unless otherwise noted.

The weight of the trailer, including the trailer and all cargo in the trailer, cannot exceed the maximum trailer weight rating for the vehicle. The allowable trailer weight might be reduced by the weight of the vehicle options, accessories, passengers,

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19 or cargo in the tow vehicle. To determine the maximum trailer weight rating:

1. Find the Gross Combined

Weight Rating for the vehicle as shown on the Trailering

Information Label.

2. Subtract the following:

Vehicle curb weight as shown on the Trailering

Information Label

Weight of the driver and passengers

Weight of cargo in the tow vehicle

Hitch hardware weight including the draw bar, and equalizer bars

Weight of accessories added to the vehicle

A step bumper trailer hitch can only support a total trailer weight up to

2 271 kg (5,000 lb). If a trailer hitch ball is added to the step bumper, check the hitch ball rating to be sure it is higher than the total trailer weight.

Maximum Trailer Tongue

Weight Rating

The Maximum Trailer Tongue

Weight Rating is the allowable trailer tongue weight that the vehicle can support using a conventional trailer hitch. It may be necessary to reduce the overall trailer weight to stay within the maximum trailer tongue weight rating while still maintaining the correct trailer load balance.

The Maximum Trailer Tongue

Weight Rating for a conventional trailer hitch is shown on the

Trailering Information Label.

Driving and Operating 295

Do not exceed a maximum trailer tongue weight of 567 kg (1,250 lb) for a conventional trailer hitch.

The trailer tongue weight contributes to the Gross Vehicle Weight (GVW).

GVW includes the curb weight of your vehicle, any passengers, cargo, equipment, and the trailer tongue weight. Vehicle options, passengers, cargo, and equipment reduce the maximum allowable tongue weight the vehicle can carry, which also reduces the maximum allowable trailer weight.

Trailer Load Balance

The correct trailer load balance must be maintained to ensure trailer stability. Incorrect load balance is a leading cause of trailer sway.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

296 Driving and Operating

The trailer tongue weight (1) should be 10 – 15% of the total loaded trailer weight (2). Some specific trailer types, such as boat trailers, fall outside of this range. Always refer to the trailer owner ’ s manual for the recommended trailer tongue weight for each trailer. Never exceed the maximum loads for the vehicle, hitch, and trailer.

The trailer load balance percentage is calculated as: weight (1) divided by weight (2) times 100.

After loading the trailer, separately weigh the trailer and then the trailer tongue and calculate the trailer load balance percentage to see if the weights and distribution are appropriate for your vehicle. If the trailer weight is too high, it may be possible to transfer some of the cargo into your vehicle. If the trailer tongue weight is too high or too low, it may be possible to rearrange some of the cargo inside of the trailer.

Do not exceed the maximum allowable tongue weight for the vehicle. Use the shortest hitch extension that will position the hitch ball closest to the vehicle. This will help reduce the effect of trailer tongue weight on the trailer hitch and rear axle.

If a cargo carrier is used in the trailer hitch receiver, choose a carrier that positions the load as close to the vehicle as possible.

Make sure the total weight, including the carrier, is no more than half of the maximum allowable tongue weight for the vehicle or

227 kg (500 lb), whichever is less.

Rear Gross Axle Weight Rating

(GAWR-RR)

The GAWR-RR is the total weight that can be supported by the rear axle of the vehicle. Do not exceed the GAWR-RR for the vehicle, with the tow vehicle and trailer fully loaded for the trip including the weight of the trailer tongue. If using a weight-distributing hitch, do not exceed the GAWR-RR before applying the weight distribution spring bars.

The GAWR-RR for the vehicle is on the Trailering Information Label.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

Ask your dealer for trailering information or assistance.

Towing Equipment

Hitches

Conventional Hitch

A conventional hitch is bolted to the frame or cross member of the tow vehicle, and is generally rated Class

2, 3, or 4.

Gooseneck Hitch

A gooseneck hitch is designed to be coupled to a special hitch leveraging a hitch ball, and is mounted over the rear axle in the truck bed.

Fifth-Wheel Hitch

A fifth-wheel hitch is mounted over the rear axle in the truck bed, and leverages a hinged plate — the same type of hitch leveraged by semi trucks. Generally, fifth-wheel hitches accommodate large trailers with as many as one, two, or three axles.

Always use the correct hitch equipment for your vehicle.

Crosswinds, large trucks going by, and rough roads can affect the trailer and the hitch.

Proper hitch equipment for your vehicle helps maintain control of the vehicle-trailer combination. Many trailers can be towed using a weight-carrying hitch which has a coupler latched to the hitch ball, or a tow eye latched to a pintle hook.

Other trailers may require a weight-distributing hitch that uses spring bars to distribute the trailer tongue weight between your vehicle and trailer axles. Fifth-wheel and gooseneck hitches may also be used. See “ Maximum Trailer Tongue

Weight ” under

Trailer Towing

292

for weight limits with various hitch types.

Avoid sharp turns when using a step-bumper hitch to prevent damage. Make wider turns to prevent contact between your trailer and your bumper.

Driving and Operating 297

Consider using mechanical sway controls with any trailer. Ask a trailering professional about sway controls or refer to the trailer manufacturer's recommendations and instructions.

Weight-Distributing Hitch and

Adjustment

A weight-distributing hitch may be useful with some trailers. Use the following guidelines to determine if a weight-distributing hitch should be used.

Tires

Do not tow a trailer while using a compact spare tire on the vehicle.

Tires must be properly inflated to support loads while towing a trailer. See

Tires

379

for instructions on proper tire inflation.

Fifth-Wheel and Gooseneck

Trailering

Fifth-wheel and gooseneck trailers can be used with many pickup models. These trailers place a larger percentage of the weight

(kingpin weight) on the tow vehicle than conventional trailers. Make sure this weight does not cause the vehicle to exceed GAWR or GVWR.

Fifth-wheel or gooseneck kingpin weight should be 15 – 25% of the trailer weight up to the maximum amount specified in the trailering chart for the vehicle. See “ Trailer

Weight" under

Trailer Towing

292

The hitch should be in the pickup bed so that its centerline is over or slightly in front of the rear axle. Take care that it is not so far forward that it will contact the back of the cab in sharp turns. This is especially important for short box pickups.

Trailer pin box extensions and sliding fifth-wheel hitch assemblies may be used. There should be at least 15 cm (6 in) of clearance between the top of the pickup box and the bottom of the trailer shelf that extends over the box.

Make sure the hitch is attached to the tow vehicle frame rails. Do not use the pickup box for support.

Safety Chains

Always attach safety chains between the vehicle and the trailer.

Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer.

If the trailer being towed weighs up to 2 271 kg (5,000 lb) with a factory-installed step bumper, safety chains may be attached to the

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19 attaching points on the bumper; otherwise, safety chains should be attached to holes on the trailer hitch.

Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch. Always leave enough slack in the safety chains to allow the combination to turn. Never allow safety chains to drag on the ground.

Trailer Brakes

Loaded trailers over 900 kg

(2,000 lb) must be equipped with brake systems and with brakes for each axle. Trailer braking equipment conforming to Canadian Standards

Association (CSA) requirement

CAN3-D313, or its equivalent, is recommended.

State or local regulations may require trailers to have their own braking system if the loaded weight of the trailer exceeds certain minimums that can vary from state to state. Read and follow the instructions for the trailer brakes so they are installed, adjusted, and maintained properly. Never attempt to tap into your vehicle's hydraulic brake system. If you do, both the vehicle antilock brakes and the trailer brakes may not function, which could result in a crash.

Auxiliary Battery

If equipped, the vehicle's auxiliary battery can be used to supply electrical power to additional equipment that may be added, such as a slide-in camper.

Locate the auxiliary battery connector under the hood on the driver side of the vehicle, next to the engine compartment fuse block.

Follow the proper installation instructions included with any electrical equipment that is installed.

Caution

To prevent draining the auxiliary battery, always turn off electrical equipment when not in use and do not use any equipment that

Tow/Haul Mode is most useful when towing a heavy trailer or carrying a large or heavy load:

Through rolling terrain.

In stop-and-go traffic.

In busy parking lots.

Operating the vehicle in Tow/Haul

Mode when lightly loaded or not towing will not cause damage; however, it is not recommended and may result in unpleasant engine and transmission driving characteristics, heavy or light steering efforts, and reduced fuel economy.

Integrated Trailer Brake

Control System

The vehicle may have an Integrated

Trailer Brake Control (ITBC) system for use with electric trailer brakes or most electric over hydraulic trailer brake systems. These instructions apply to both types of electric trailer brakes.

This symbol is on the Trailer Brake

Control Panel on vehicles with an

ITBC system. The power output to the trailer brakes is proportional to the amount of vehicle braking. This available power output to the trailer brakes can be adjusted to a wide range of trailering situations.

The ITBC system is integrated with the vehicle ’ s brake, antilock brake, and StabiliTrak/Electronic Stability

Control (ESC) systems. In trailering conditions that cause the vehicle ’ s antilock brake or StabiliTrak/ESC systems to activate, power sent to the trailer's brakes will be automatically adjusted to minimize

If the CHECK TRAILER WIRING message only reappears when connecting the trailer wiring harness to the vehicle, the electrical fault is on the trailer side.

SERVICE TRAILER BRAKE

SYSTEM: This message will display when there is a problem with the

ITBC system. If this message continues over multiple ignition cycles, have the vehicle serviced.

If either the CHECK TRAILER

WIRING or SERVICE TRAILER

BRAKE SYSTEM message displays while driving, the ITBC system may not be fully functional or may not function at all. When traffic conditions allow, carefully pull the vehicle over to the side of the road and turn the ignition off. Check the wiring connection to the trailer and turn the ignition back on. If either of these messages continues, either the vehicle or trailer needs service.

A GM dealer may be able to diagnose and repair problems with the trailer. However, any diagnosis and repair of the trailer is not covered under the vehicle warranty.

Contact your trailer dealer for assistance with trailer repairs and trailer warranty information.

Trailer Sway

Control (TSC)

Vehicles with StabiliTrak/Electronic

Stability Control (ESC) have a

Trailer Sway Control (TSC) feature.

Trailer sway is unintended side-to-side motion of a trailer while towing. If the vehicle is towing a trailer and the TSC detects that sway is increasing, the vehicle brakes are selectively applied at each wheel, to help reduce excessive trailer sway. If equipped with the Integrated Trailer Brake

Control (ITBC) system, and the trailer has an electric brake system,

StabiliTrak/ESC may also apply the trailer brakes.

If TSC is enabled, the Traction

Control System (TCS)/StabiliTrak/

ESC warning light will flash on the instrument cluster. Reduce vehicle speed by gradually removing your foot from the accelerator. If trailer sway continues, StabiliTrak/ESC can reduce engine torque to help slow the vehicle. TSC will not function if StabiliTrak/ESC is turned off. See

Traction Control/Electronic

Stability Control

Warning

Trailer sway can result in a crash and in serious injury or death, even if the vehicle is equipped with TSC.

Warning (Continued)

If the trailer begins to sway, reduce vehicle speed by gradually removing your foot from the accelerator. Then pull over to check the trailer and vehicle to help correct possible causes, including an improperly or overloaded trailer, unrestrained cargo, improper trailer hitch configuration, or improperly inflated or incorrect vehicle or trailer tires. See

for trailer ratings and hitch setup recommendations.

Aftermarket Electronic Trailer

Sway Control Devices

Some trailers may come equipped with an electronic device designed to reduce or control trailer sway.

Aftermarket equipment manufacturers also offer similar devices that connect to the wiring between the trailer and the vehicle.

These devices may interfere with the vehicle ’ s trailer brake or other systems, including integrated anti-sway systems, if equipped.

Messages related to trailer connections or trailer brakes could appear on the DIC. The effects of these aftermarket devices may have on vehicle handling or trailer brake performance is not known.

{

Warning

Use of aftermarket electronic trailer sway control devices could result in reduced trailer brake performance, loss of trailer brakes, or other malfunctions, and result in a crash. You or others could be seriously injured or killed. Before using one of these devices:

Ask the device or trailer manufacturer if the device has been thoroughly tested for compatibility with the make, model, and year of

your vehicle and any optional equipment installed on your vehicle.

Before driving, check the trailer brakes are working properly, if equipped. Drive the vehicle with the trailer attached on a level road surface that is free of traffic at about 32-40 km/h

(20-25 mph) and fully apply the manual trailer brake apply lever. Also, check the trailer brake lamps and other lamps are functioning correctly.

If the trailer brakes are not operating properly at any time, or if a DIC message indicates problems with the trailer connections or trailer brakes, carefully pull the vehicle over to the side of the road when traffic conditions allow.

Trailer Tires

Special Trailer (ST) tires differ from vehicle tires. Trailer tires are designed with stiff sidewalls to help prevent sway and to support heavy loads. These features can make it difficult to determine if the trailer tire pressures are low only based on a visual inspection.

Always check all trailer tire pressures before each trip when the tires are cool. Low trailer tire pressure is a leading cause of trailer tire blow-outs.

If the vehicle is equipped with a trailer tire pressure monitoring system, see the trailer tire pressure monitoring system description and the trailering app.

Trailer tires deteriorate over time.

The trailer tire sidewall will show the week and year the tire was manufactured. Many trailer tire manufacturers recommend replacing tires more than six years old.

Overloading is another leading cause of trailer tire blow-outs. Never load your trailer with more weight than the tires are designed to support. The load rating is located on the trailer tire sidewall.

Always know the maximum speed rating for the trailer tires before driving. This may be significantly lower than the vehicle tire speed rating. The speed rating may be on the trailer tire sidewall. If the speed rating is not shown, the default trailer tire speed rating is 105 km/h

(65 mph).

installed. The vehicle can be damaged if either the front or rear axle ratings or the Gross Vehicle

Weight Rating (GVWR) are exceeded.

The plow the vehicle can carry depends on many things, such as:

The options the vehicle came with, and the weight of those options.

The weight and number of passengers to be carried.

The weight of items added to the vehicle, like a tool box or truck cap.

The total weight of any additional cargo to be carried.

For example, if the snow plow weighs 318 kg (700 lb), the total weight of all occupants and cargo inside the cab should not exceed

135 kg (300 lb). This means that you may only be able to carry one passenger. Even this may be too

Driving and Operating 323

much if there is other equipment already adding to the weight of the vehicle.

To safely carry a snow plow on the vehicle:

Follow all aftermarket snow plow manufacturer ’ s instructions for the operation and transportation of the snow plow.

With a snow plow attached, the engine coolant temperature gauge may show a higher temperature than while driving without one. The snow plow could block the airflow to the radiator. This could be more noticeable as vehicle speed increases. At speeds above

72 km (45 mph), this may cause the engine coolant to overheat.

To increase the airflow, move the snow plow blade postion.

If driving more than 24 km

(15 mi), angle the plow blade position.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

324 Driving and Operating

Make sure the weight on the front and rear axles does not exceed the axle rating for each.

For the front axle, if more cargo or passengers must be carried, appropriate counter ballast must be installed rear of the rear axle.

Counter ballast must be properly secured so it will not move during driving.

Rear ballast may be required to ensure a proper front and rear weight distribution ratio, even though the actual weight at the front axle may be less than the front axle rating.

The snow plow manufacturer or installer can assist in determining the amount of rear ballast required, to help make sure the snow plow/vehicle combination does not exceed the GVW rating, the front and rear axle ratings, and the front and rear weight distribution ratio.

The total vehicle must not exceed the GVW rating.

Front axle reserve capacity is the difference between the Gross Axle

Weight Rating (GAWR) and the front axle weight of the vehicle with full fuel and passengers. This is the amount of weight that can be added to the front axle before reaching the front GAWR.

United States

Canada

The front axle reserve capacity for the vehicle is in the lower right corner of the Certification/Tire label.

To calculate the amount of weight any front accessory, such as a snow plow, is adding to the front axle, use this formula:

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/11/19

(W x (A + W.B.)) /W.B.= Weight the accessory is adding to the front axle.

Where:

W = Weight of added accessory

A = Distance that the accessory is in front of the front axle

W.B. = Vehicle Wheelbase

For example, adding a 318 kg

(700 lb) snow plow actually adds more than 318 kg (700 lb) to the front axle. Using the formula, if the snow plow is 122 cm (4 ft) in front of the front axle and the wheelbase is

305 cm (10 ft), then:

W = 318 kg (700 lb)

A = 122 cm (4 ft)

W.B. = 305 cm (10 ft)

(W x (A + W.B.)/W.B. =

(318 x (122 + 305))/305 = 445 kg

(980 lb)

This means if the front axle reserve capacity is more than 445 kg

(980 lb), the snow plow could be added without exceeding the front GAWR.

Heavier equipment can be added on the front of the vehicle if less cargo or fewer passengers are carried, or by positioning cargo toward the rear. This reduces the load on the front. However, the front GAWR, rear GAWR, and Gross Vehicle

Weight Rating (GVWR) must never be exceeded.

{

Warning

On some vehicles that have certain front mounted equipment, such as a snow plow, it may be possible to load the front axle to the front Gross Axle Weight

Rating (GAWR) but not have

enough weight on the rear axle to have proper braking performance.

If the brakes cannot work properly, the vehice could crash.

Always follow the snow plow manufacturer or installer's recommendation for rear ballast to ensure a proper front and rear weight distribution ratio.

Maintaining a proper front and rear weight distribution ratio is necessary to provide proper braking performance.

Total vehicle reserve capacity is the difference between the GVWR and the weight of the truck with full fuel and passengers. It is the amount of weight that can be added to the vehicle before reaching the GVWR.

Reserve capacity numbers are intended as a guide when selecting the amount of equipment or cargo the truck can carry. If unsure of the vehicle's front, rear, or total weight,

If the vehicle has a diesel engine, see the Duramax diesel supplement.

Engine Oil

For diesel engine vehicles, see

“ Engine Oil ” in the Duramax diesel supplement.

To ensure proper engine performance and long life, careful attention must be paid to engine oil.

Following these simple, but important steps will help protect your investment:

Use engine oil approved to the proper specification and of the proper viscosity grade. See

“ Selecting the Right Engine Oil ” in this section.

Vehicle Care 339

Check the engine oil level regularly and maintain the proper oil level. See “ Checking

Engine Oil ” and “ When to Add

Engine Oil ” in this section.

Change the engine oil at the appropriate time. See

Engine Oil

Life System

341

Always dispose of engine oil properly. See “ What to Do with

Used Oil ” in this section.

Checking Engine Oil

Check the engine oil level regularly, every 650 km (400 mi), especially prior to a long trip. The engine oil dipstick handle is a loop. See

Engine Compartment Overview

332

for the location.

{

Warning

The engine oil dipstick handle may be hot; it could burn you.

Use a towel or glove to touch the dipstick handle.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

340 Vehicle Care

If a low oil Driver Information Center

(DIC) message displays, check the oil level.

Follow these guidelines:

To get an accurate reading, park the vehicle on level ground.

Check the engine oil level after the engine has been off for at least two hours. Checking the engine oil level on steep grades or too soon after engine shutoff can result in incorrect readings.

Accuracy improves when checking a cold engine prior to starting. Remove the dipstick and check the level.

If unable to wait two hours, the engine must be off for at least

15 minutes if the engine is warm, or at least 30 minutes if the engine is not warm. Pull out the dipstick, wipe it with a clean paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level.

When to Add Engine Oil

If the oil is below the cross-hatched area at the tip of the dipstick and the engine has been off for at least

15 minutes, add 1 L (1 qt) of the recommended oil and then recheck the level. See “ Selecting the Right

Engine Oil ” later in this section for an explanation of what kind of oil to use. For engine oil crankcase capacity, see

Capacities and

Specifications

457

Caution

Do not add too much oil. Oil levels above or below the acceptable operating range shown on the dipstick are harmful to the engine. If the oil level is

(Continued)

Caution (Continued)

above the operating range (i.e., the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range), the engine could be damaged. Drain the excess oil or limit driving of the vehicle, and seek a service professional to remove the excess oil.

See

Engine Compartment Overview

332

for the location of the engine oil fill cap.

Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when through.

Selecting the Right Engine Oil

Selecting the right engine oil depends on both the proper oil specification and viscosity grade.

See

Recommended Fluids and

Lubricants

451

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

Specification

Use full synthetic engine oils that meet the dexos1 specification.

Engine oils that have been approved by GM as meeting the dexos1 specification are marked with the dexos1 approved logo.

Caution

Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty.

Viscosity Grade

Use SAE 0W-20 viscosity grade engine oil for the 5.3L and 6.2L

V8 engines.

Use SAE 5W-30 viscosity grade engine oil for the 2.7L L4, 4.3L

V6 and 6.6L V8 engines. Cold

Temperature Operation: In an area of extreme cold, where the temperature falls below − 29 °C

( − 20 °F), use SAE 0W-30 oil. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures.

When selecting an oil of the appropriate viscosity grade, it is recommended to select an oil of the correct specification. See

“ Specification ” earlier in this section.

Engine Oil Additives/Engine

Oil Flushes

Do not add anything to the oil. The recommended oils meeting the dexos1 specification are all that is needed for good performance and engine protection.

Engine oil system flushes are not recommended and could cause engine damage not covered by the vehicle warranty.

Vehicle Care 341

What to Do with Used Oil

Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer's warnings about the use and disposal of oil products.

Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash or pouring it on the ground, into sewers, or into streams or bodies of water. Recycle it by taking it to a place that collects used oil.

Engine Oil Life System

When to Change Engine Oil

This vehicle has a computer system that indicates when to change the engine oil and filter. This is based on a combination of factors which

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

342 Vehicle Care

include engine revolutions, engine temperature, and miles driven.

Based on driving conditions, the mileage at which an oil change is indicated can vary considerably. For the oil life system to work properly, the system must be reset every time the oil is changed.

On some vehicles, when the system has calculated that oil life has been diminished, a CHANGE ENGINE

OIL SOON message comes on to indicate that an oil change is necessary. Change the oil as soon as possible within the next 1 000 km

(600 mi). It is possible that, if driving under the best conditions, the oil life system might indicate that an oil change is not necessary for up to a year. The engine oil and filter must be changed at least once a year and, at this time, the system must be reset. For vehicles without the

CHANGE ENGINE OIL SOON message, an oil change is needed when the REMAINING OIL LIFE percentage is near 0%. Your dealer has trained service people who will perform this work and reset the system. It is also important to check the oil regularly over the course of an oil drain interval and keep it at the proper level.

If the system is ever reset accidentally, the oil must be changed at 5 000 km (3,000 mi) since the last oil change.

Remember to reset the oil life system whenever the oil is changed.

How to Reset the Engine Oil

Life System

Reset the system whenever the engine oil is changed so that the system can calculate the next engine oil change. Always reset the engine oil life to 100% after every oil change. It will not reset itself. To reset the engine oil life system:

1. Display the oil life percentage on the DIC. See

Driver

Information Center (DIC) (Base

Level)

148

Driver Information Center (DIC)

(Midlevel and Uplevel)

149

2. Press the thumbwheel on the steering wheel, or the trip odometer reset stem if the vehicle does not have DIC controls, for several seconds.

When the confirmation message displays, select YES.

The oil life will change to 100%.

The oil life system can also be reset as follows:

1. Display the oil life percentage on the DIC. See

Driver

Information Center (DIC) (Base

Level)

All Engines Except 6.6L

V8 Engine (L8T)

The vehicle has electric cooling fan(s). The fans may be heard spinning at low speed during most everyday driving. The fans may turn off if no cooling is required. Under heavy vehicle loading, trailer towing, high outside temperatures, or operation of the air conditioning system, the fans may change to high speed and an increase in fan noise may be heard. This is normal and indicates that the cooling system is functioning properly. The fans will change to low speed when additional cooling is no longer required.

The electric engine cooling fans may run after the engine has been turned off. This is normal and no service is required.

6.6L V8 Engine (L8T) Only

The vehicle has a clutched engine cooling fan. When the clutch is engaged, the fan spins faster to provide more air to cool the engine.

In most everyday driving conditions,

Vehicle Care 353

the fan is spinning slower and the clutch is not fully engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing, and/or high outside temperatures, the fan speed increases as the clutch more fully engages, so an increase in fan noise may be heard. This is normal and should not be mistaken as the transmission slipping or making extra shifts. It is merely the cooling system functioning properly. The fan will slow down when additional cooling is not required and the clutch partially disengages.

This fan noise may be heard when starting the engine. It will go away as the fan clutch partially disengages.

Power Steering Fluid

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

354 Vehicle Care

The power steering fluid reservoir is in the engine compartment on the driver side of the vehicle. See

Engine Compartment Overview

332

for reservoir location.

When to Check Power Steering

Fluid

It is not necessary to regularly check power steering fluid unless there is a leak suspected in the system or an unusual noise is heard. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

How to Check Power Steering

Fluid

To check the power steering fluid:

1. Set the ignition off and let the engine compartment cool down.

2. Wipe the cap and the top of the reservoir clean.

3. Unscrew the cap and wipe the dipstick with a clean rag.

4. Replace the cap and completely tighten it.

5. Remove the cap again and look at the fluid level on the dipstick.

The level should be between the

ADD and FULL marks. If necessary, add only enough fluid to bring the level up to the hashed area between the ADD and FULL marks.

To prevent contamination of brake fluid, never check or fill the power steering reservoir with the brake master cylinder cover off.

What to Use

Caution

Use of the incorrect fluid may damage the vehicle and the damages may not be covered by the vehicle warranty. Always use the correct fluid listed in

Recommended Fluids and

Lubricants

451

To determine what kind of fluid to use, see

Recommended Fluids and

Lubricants

451

. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals.

Washer Fluid

What to Use

When windshield washer fluid needs to be added, be sure to read the manufacturer's instructions before use. Use a fluid that has sufficient protection against freezing in an area where the temperature may fall below freezing.

Adding Washer Fluid

The vehicle has a low washer fluid message on the DIC that comes on when the washer fluid is low. The message is displayed for

15 seconds at the start of each ignition cycle. When the WASHER

FLUID LOW ADD FLUID message displays, washer fluid will need to be added to the windshield washer fluid reservoir.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See

Engine

Compartment Overview

332

for reservoir location.

Caution

Do not use washer fluid that contains any type of water repellent coating. This can cause the wiper blades to chatter or skip.

Do not use engine coolant

(antifreeze) in the windshield washer. It can damage the windshield washer system and paint.

Do not mix water with ready-to-use washer fluid.

Water can cause the

Caution (Continued)

solution to freeze and damage the washer fluid tank and other parts of the washer system.

When using concentrated washer fluid, follow the manufacturer instructions for adding water.

Fill the washer fluid tank only three-quarters full when it is very cold. This allows for fluid expansion if freezing occurs, which could damage the tank if it is completely full.

Brakes

Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed.

The sound can come and go or be heard all the time the vehicle is moving, except when applying the brake pedal firmly.

Vehicle Care 355

{

Warning

The brake wear warning sound means that soon the brakes will not work well. That could lead to a crash. When the brake wear warning sound is heard, have the vehicle serviced.

Caution

Continuing to drive with worn-out brake pads could result in costly brake repair.

Some driving conditions or climates can cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with the brakes.

Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the

457

Brake linings should always be replaced as complete axle sets.

Brake Pedal Travel

See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign that brake service may be required.

Replacing Brake System Parts

Always replace brake system parts with new, approved replacement parts. If this is not done, the brakes may not work properly. The braking performance expected can change in many other ways if the wrong replacement brake parts are installed or parts are improperly installed.

Brake Pad Life System

When to Change Brake Pads

This vehicle has a system that estimates the remaining life of the front and rear brake pads. Brake pad life is displayed in the Driver

Information Center (DIC), along with a percentage for each axle. The system must be reset every time the brake pads are changed.

When the system has determined that the brake pads need to be replaced, a message will display, which may include mileage remaining.

Brake pads should always be replaced as complete axle sets.

How to Reset the Brake Pad

Life System

The system will automatically detect when significantly worn brake pads are replaced. When the ignition is turned on after new pads and wear sensors are installed, a message will display. Follow the prompts to reset the system.

The brake pad life system can also be manually reset:

1. Display Brake Pad Life on the

DIC. See

Driver Information

Center (DIC) (Base Level)

148

Driver Information Center (DIC)

(Midlevel and Uplevel)

2. Press the thumbwheel or the trip odometer reset stem if the vehicle does not have DIC buttons. Select front or rear pads as appropriate.

3. Select YES on the confirmation message, or press the trip odometer reset stem on a base level DIC. Repeat for pads on the other axle if they were also replaced.

How to Disable the Brake Pad

Life System

The brake pad life system can be turned off. This may be necessary if aftermarket brake pads without wear sensors are installed. When the system is turned off, the front and rear brake pad life percentages will not display. However, the built-in

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19 wear indicators that make a high-pitched warning sound when the brake pads are worn can still determine when the pads should be replaced. See

149

2. Select DISABLE.

To turn the brake pad life system back on, follow the above steps but select ENABLE in Step 2.

Brake Fluid

The brake master cylinder reservoir is filled with GM approved DOT 4

(1500) or DOT 3 (2500/3500) brake fluid as indicated on the reservoir cap. See

Engine Compartment

Overview

332

for the location of the reservoir.

Checking Brake Fluid

With the vehicle in P (Park) on a level surface, the brake fluid level should be between the minimum and maximum marks on the brake fluid reservoir.

There are only two reasons why the brake fluid level in the reservoir may go down:

Normal brake lining wear. When new linings are installed, the fluid level goes back up.

A fluid leak in the brake hydraulic system. Have the brake hydraulic system fixed.

With a leak, the brakes will not work well.

Always clean the brake fluid reservoir cap and the area around the cap before removing it.

Do not top off the brake fluid.

Adding fluid does not correct a leak.

If fluid is added when the linings are

Vehicle Care 357

worn, there will be too much fluid when new brake linings are installed. Add or remove fluid, as necessary, only when work is done on the brake hydraulic system.

{

Warning

If too much brake fluid is added, it can spill on the engine and burn, if the engine is hot enough. You or others could be burned, and the vehicle could be damaged.

Add brake fluid only when work is done on the brake hydraulic system.

When the brake fluid falls to a low level, the brake warning light comes on. See

Brake System Warning

for battery location.

Stop/Start System

Vehicles equipped with a 2.7L L3B,

3.0L LM2, 5.3L L84 or 6.2L L87 are equipped with a Stop/Start system to shut off the engine to help conserve fuel. See

Stop/Start

System

213

Vehicles with the Stop/Start system have an Absorbed Glass Mat (AGM)

12-volt battery. Installation of a standard 12-volt battery will result in reduced 12-volt battery life. When using a 12-volt battery charger on the 12-volt AGM battery, some chargers have an AGM battery setting on the charger. If available, use the AGM setting on the charger to limit charge voltage to 14.8 volts.

Follow the charger manufacturer ’ s instructions.

Electrical System

Overload

The vehicle has fuses to protect against an electrical system overload. Fuses also protect power devices in the vehicle.

Replace a bad fuse with a new one of the identical size and rating.

If there is a problem on the road and a fuse needs to be replaced, there are some spare fuses and a fuse puller in the left instrument panel fuse block. The same amperage fuse can also be borrowed. Choose some feature of the vehicle that is not needed to use and replace it as soon as possible.

Headlamp Wiring

An electrical overload may cause the lamps to go on and off, or in some cases to remain off. Have the headlamp wiring checked right away if the lamps go on and off or remain off.

Windshield Wipers

If the wiper motor overheats due to heavy snow or ice, the windshield wipers will stop until the motor cools and will then restart.

Although the circuit is protected from electrical overload, overload due to heavy snow or ice may cause wiper linkage damage.

Always clear ice and heavy snow from the windshield before using the windshield wipers.

If the overload is caused by an electrical problem and not snow or ice, be sure to get it fixed.

Fuses and Circuit

Breakers

The wiring circuits in the vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of damage caused by electrical problems.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

{

Danger

Fuses and circuit breakers are marked with their ampere rating.

Do not exceed the specified amperage rating when replacing fuses and circuit breakers. Use of an oversized fuse or circuit breaker can result in a vehicle fire. You and others could be seriously injured or killed.

To check a fuse, look at the silver-colored band inside the fuse.

If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating.

Fuses of the same amperage can be temporarily borrowed from another fuse location, if a fuse goes out. Replace the fuse as soon as possible.

Engine Compartment

Fuse Block

If the vehicle has a diesel engine, see the Duramax diesel supplement.

The engine compartment fuse block is in the engine compartment, on the passenger side of the vehicle for

1500 and driver side of vehicle for

2500/3500.

Vehicle Care 371

Caution

Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.

A fuse puller is available in the left instrument panel end cap.

Original equipment all-season tires can be identified by the last two characters of this TPC code, which will be “ MS.

”

Consider installing winter tires on the vehicle if frequent driving on snow or ice-covered roads is expected. All-season tires provide adequate performance for most winter driving conditions, but they may not offer the same level of traction or performance as winter tires on snow or ice-covered roads.

Winter Tires

This vehicle was not originally equipped with winter tires. Winter tires are designed for increased traction on snow and ice-covered roads. Consider installing winter tires on the vehicle if frequent driving on ice or snow covered roads is expected. See your dealer for details regarding winter tire availability and proper tire selection.

Also, see

Buying New Tires

399

With winter tires, there may be decreased dry road traction, increased road noise, and shorter tread life. After changing to winter tires, be alert for changes in vehicle handling and braking.

If using winter tires:

Use tires of the same brand and tread type on all four wheel positions.

Use only radial ply tires of the same size, load range, and speed rating as the original equipment tires.

Winter tires with the same speed rating as the original equipment tires may not be available for H, V, W, Y, and ZR speed rated tires. If winter tires with a lower speed rating are chosen, never exceed the tire's maximum speed capability.

Low-Profile Tires

If the vehicle has 275/60R20 or

275/50R22 size tires, they are classified as low-profile tires.

Caution

Low-profile tires are more susceptible to damage from road hazards or curb impact than standard profile tires. Tire and/or wheel assembly damage can occur when coming into contact with road hazards like potholes, or sharp edged objects, or when sliding into a curb. The warranty does not cover this type of damage. Keep tires set to the correct inflation pressure and when possible, avoid contact with curbs, potholes, and other road hazards.

. How the

vehicle is loaded affects vehicle handling and ride comfort. Never load the vehicle with more weight than it was designed to carry.

When to Check

Check the pressure of the tires once a month or more.

Do not forget the spare tire, if the vehicle has one. See

Full-Size Spare Tire

418

for additional information.

How to Check

Use a good quality pocket-type gauge to check tire pressure.

Proper tire inflation cannot be determined by looking at the tire.

Check the tire inflation pressure when the tires are cold, meaning the vehicle has not been driven for at least three hours or no more than 1.6 km (1 mi).

Remove the valve cap from the tire valve stem. Press the tire gauge firmly onto the valve to get a pressure measurement.

If the cold tire inflation pressure matches the recommended pressure on the Tire and

Loading Information label, no further adjustment is necessary.

If the inflation pressure is low, add air until the recommended pressure is reached. If the inflation pressure is high, press on the metal stem in the center of the tire valve to release air.

Re-check the tire pressure with the tire gauge.

Put the valve caps back on the valve stems to keep out dirt and moisture and prevent leaks. Use only valve caps designed for the vehicle by GM. TPMS sensors could be damaged and would not be covered by the vehicle warranty.

Tire Pressure for

High-Speed Operation

{

Warning

Driving at high speeds, 160 km/h

(100 mph) or higher, puts additional strain on tires.

Sustained high-speed driving causes excessive heat buildup and can cause sudden tire failure.

This could cause a crash, and you or others could be killed.

Some high-speed rated tires require inflation pressure adjustment for high-speed operation. When speed limits and road conditions allow the vehicle to be driven at high speeds, make sure the tires are rated for high-speed operation, are in excellent condition, and are set to the correct cold tire inflation pressure for the vehicle load.

Tire Pressure Monitor

System

The Tire Pressure Monitor System

(TPMS) uses radio and sensor technology to check tire pressure levels. The TPMS sensors monitor the air pressure in your tires and transmit tire pressure readings to a receiver located in the vehicle.

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system

(TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated.

Vehicle Care 389

Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly.

The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

390 Vehicle Care

remain continuously illuminated.

This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.

When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.

Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the

TPMS to continue to function properly.

Radio Frequency Statement

471

Tire Pressure Monitor

Operation

This vehicle may have a Tire

Pressure Monitor System (TPMS).

The TPMS is designed to warn the driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly. The TPMS sensors monitor the air pressure in the tires and transmit the tire pressure readings to a receiver located in the vehicle.

When a low tire pressure condition is detected, the TPMS illuminates the low tire pressure warning light located on the instrument cluster.

If the warning light comes on, stop as soon as possible and inflate the tires to the recommended pressure shown on the Tire and Loading

Information label. See

Vehicle Load

Limits

200

A message to check the pressure in a specific tire displays in the Driver

Information Center (DIC). The low tire pressure warning light and the

DIC warning message come on at each ignition cycle until the tires are inflated to the correct inflation pressure. If the vehicle has DIC buttons, tire pressure levels can be viewed. For additional information and details about the DIC operation and displays, see

Driver Information

Center (DIC) (Base Level)

148

Driver Information Center (DIC)

(Midlevel and Uplevel)

149

The low tire pressure warning light may come on in cool weather when the vehicle is first started, and then turn off as the vehicle is driven. This could be an early indicator that the air pressure is getting low and needs to be inflated to the proper pressure.

A Tire and Loading Information label shows the size of the original equipment tires and the correct

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19 inflation pressure for the tires when they are cold. See

Caution

Tire sealant materials are not all the same. A non-approved tire sealant could damage the TPMS sensors. TPMS sensor damage caused by using an incorrect tire sealant is not covered by the vehicle warranty. Always use only the GM approved tire sealant available through your dealer or included in the vehicle.

TPMS Malfunction Light and

Message

The TPMS will not function properly if one or more of the TPMS sensors are missing or inoperable. When the system detects a malfunction, the low tire pressure warning light flashes for about one minute and then stays on for the remainder of the ignition cycle. A DIC warning message also displays. The malfunction light and DIC warning message come on at each ignition cycle until the problem is corrected.

Some of the conditions that can cause these to come on are:

One of the road tires has been replaced with the spare tire. The spare tire does not have a

TPMS sensor. The malfunction light and the DIC message should go off after the road tire is replaced and the sensor matching process is performed successfully. See "TPMS Sensor

Matching Process" later in this section.

Vehicle Care 391

The TPMS sensor matching process was not done or not completed successfully after rotating the tires. The malfunction light and the DIC message should go off after successfully completing the sensor matching process. See

"TPMS Sensor Matching

Process" later in this section.

One or more TPMS sensors are missing or damaged. The malfunction light and the DIC message should go off when the

TPMS sensors are installed and the sensor matching process is performed successfully. See your dealer for service.

Replacement tires or wheels do not match the original equipment tires or wheels. Tires and wheels other than those recommended could prevent the TPMS from functioning properly. See

392 Vehicle Care

Operating electronic devices or being near facilities using radio wave frequencies similar to the

TPMS could cause the TPMS sensors to malfunction.

If the TPMS is not functioning properly, it cannot detect or signal a low tire pressure condition. See your dealer for service if the TPMS malfunction light and DIC message come on and stay on.

Tire Fill Alert (If Equipped)

This feature provides visual and audible alerts outside the vehicle to help when inflating an underinflated tire to the recommended cold tire pressure.

When the low tire pressure warning light comes on:

1. Park the vehicle in a safe, level place.

2. Set the parking brake firmly.

3. Place the vehicle in P (Park).

4. Add air to the tire that is underinflated. The turn signal lamp will flash.

When the recommended pressure is reached, the horn sounds once and the turn signal lamp will stop flashing and briefly turn solid.

Repeat these steps for all underinflated tires that have illuminated the low tire pressure warning light.

{

Warning

Overinflating a tire could cause the tire to rupture and you or others could be injured. Do not exceed the maximum pressure listed on the tire sidewall. See

Tire Sidewall Labeling

381

and

Vehicle Load Limits

200

If the tire is overinflated by more than 35 kPa (5 psi), the horn will sound multiple times and the turn signal lamp will continue to flash for several seconds after filling stops.

To release and correct the pressure, while the turn signal lamp is still flashing, briefly press the center of the valve stem. When the recommended pressure is reached, the horn sounds once.

If the turn signal lamp does not flash within 15 seconds after starting to inflate the tire, the tire fill alert has not been activated or is not working.

If the hazard warning flashers are on, the tire fill alert visual feedback will not work properly.

The TPMS will not activate the tire fill alert properly under the following conditions:

There is interference from an external device or transmitter.

The air pressure from the inflation device is not sufficient to inflate the tire.

There is a malfunction in the TPMS.

There is a malfunction in the horn or turn signal lamps.

The identification code of the

TPMS sensor is not registered to the system.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

The battery of the TPMS sensor is low.

If the tire fill alert does not operate due to TPMS interference, move the vehicle about 1 m (3 ft) back or forward and try again. If the tire fill alert feature is not working, use a tire pressure gauge.

TPMS Sensor Matching

Process

Each TPMS sensor has a unique identification code. The identification code needs to be matched to a new tire/wheel position after rotating the vehicle ’ s tires or replacing one or more of the TPMS sensors. Also, the TPMS sensor matching process should be performed after replacing a spare tire with a road tire containing the TPMS sensor. The malfunction light and the DIC message should go off at the next ignition cycle. The sensors are matched to the tire/wheel positions, using a TPMS relearn tool, in the following order: driver side front tire, passenger side front tire, passenger side rear tire, and driver side rear.

See your dealer for service or to purchase a relearn tool. A TPMS relearn tool can also be purchased.

See Tire Pressure Monitor Sensor

Activation Tool at www.gmtoolsandequipment.com or call 1-800-GM TOOLS

(1-800-468-6657).

There are two minutes to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer, the matching process stops and must be restarted.

The TPMS sensor matching process is:

1. Set the parking brake.

2. Turn the ignition on without starting the vehicle.

3. Uplevel DIC Only: Make sure the Tire Pressure info page option is turned on. The info pages on the DIC can be turned on and off through the

Vehicle Care 393

The Trailering App can be used to view the tire pressures after the recommended trailer tire pressures have been entered. Refer to the trailer tire placard on the trailer or the trailer tire sidewall for the recommended tire pressure.

The system is compatible with trailer tires that have placard pressure values from 103 - 689 kpa (15 -

100 psi). The hole in the wheel for the tire stem must be 11.43 mm

(0.453 in) in diameter. Use of the pressure sensors on a wheel with a different stem hole size could result in loss of air from the tire.

If a low trailer tire pressure condition is detected, the TTPMS displays a warning message on the DIC. If the warning message is displayed, stop as soon as possible and inflate the tires to the recommended pressure shown on the tire placard on the trailer.

In addition, the TTPMS monitors the temperature of the trailer tires. If the system detects a high temperature on one or more of the trailer tires, a warning message will be displayed on the DIC. If this warning message is displayed, stop as soon as possible, and inspect the overheated trailer tire. Common causes for high trailer tire temperature are underinflation, overloading, or tire damage.

TTPMS Malfunction Message

The TTPMS will not function properly if one or more of the trailer tire sensors are missing or inoperable. If the system detects a malfunction, a DIC message indicates that the system requires service. Some of the conditions that can cause the service message to occur are:

One of the trailer tires has been replaced with the spare tire which does not have a learned

TTPMS sensor. The DIC message should turn off after the pressure sensor is installed in the tire, and the learning process is performed successfully. See

"TTPMS Sensor Learning

Process" under

Trailering App

310

Vehicle Care 395

The TTPMS sensor learning process was not done or not completed successfully. The DIC message should go off after successfully completing the sensor learning process. See

"TTPMS Sensor Learning

Process" under

Trailering App

310

One or more TTPMS sensors are missing or damaged. The

DIC message should go off when the TTPMS sensors are installed and the sensor learning process is performed successfully. See "TTPMS

Sensor Learning Process" under

Trailering App

310

Operating electronic devices or being near facilities using radio wave frequencies similar to the

TTPMS could cause interference to the TTPMS which could cause loss of signal reception from the sensor.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

396 Vehicle Care

If the system does not receive the signal from an individual sensor, an error message may not occur until the vehicle has been driver for a period of time.

If the TTPMS is not functioning properly, it cannot detect or signal a low tire condition. See your dealer for service if the DIC message comes on and stays on when the trailer tire pressures have been checked and determined to be correct.

Tire Inspection

We recommend that the tires, including the spare tire, if the vehicle has one, be inspected for signs of wear or damage at least once a month.

Replace the tire if:

The indicators at three or more places around the tire can be seen.

There is cord or fabric showing through the tire's rubber.

The tread or sidewall is cracked, cut, or snagged deep enough to show cord or fabric.

The tire has a bump, bulge, or split.

The tire has a puncture, cut, or other damage that cannot be repaired well because of the size or location of the damage.

Tire Rotation

Tires should be rotated every

12 000 km (7,500 mi). See

Maintenance Schedule

441

Tires are rotated to achieve a more uniform wear for all tires.

The first rotation is the most important.

Anytime unusual wear is noticed, rotate the tires as soon as possible, check for proper tire inflation pressure, and check for damaged tires or wheels. If the unusual wear continues after the rotation, check the wheel alignment. See

When It Is Time for New Tires

Use this rotation pattern when rotating the tires if the vehicle has dual rear wheels (except polished forged aluminum wheels).

Vehicles with polished forged aluminum dual wheels have three unique wheels; a front, a rear outer and a rear inner.

These wheels cannot be rotated to another position, however, they can be rotated from left to right to the same position.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

398 Vehicle Care

Use this rotation pattern when rotating the tires if the vehicle has polished forged aluminum dual rear wheels. The spare wheel can be used in any position in the event of a flat tire, and can be rotated with the rear inner wheels. After the flat tire is repaired, if the spare is not on one of the inner rear positions, it must be replaced by the correct wheel in the front or rear outer positions.

When installing dual wheels, check that the vent holes in the inner and outer wheels on each side are lined up.

Adjust the front and rear tires to the recommended inflation pressure on the Tire and

Loading Information label after the tires have been rotated. See

Warning

Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after time. The wheel could come off and cause a crash. When changing a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, a cloth or a paper towel can be used; however, use a scraper or wire brush later to remove all rust or dirt.

Lightly coat the inner diameter of the wheel hub opening with wheel bearing grease after a wheel change or tire rotation to prevent corrosion or rust build-up. Do not get grease on the flat wheel mounting surface or on the wheel nuts or bolts.

Reset the Tire Pressure Monitor

System (TPMS), if the vehicle has one. See

Tire Pressure

Monitor Operation

When It Is Time for New

Tires

Factors, such as maintenance, temperatures, driving speeds, vehicle loading, and road conditions affect the wear rate of the tires.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

Treadwear indicators are one way to tell when it is time for new tires.

Treadwear indicators appear when the tires have only 1.6 mm (1/16 in) or less of tread remaining. Some commercial truck tires may not have treadwear indicators. See

Tire

Inspection

396

and

Tire Rotation

396

for additional information.

The rubber in tires ages over time.

This also applies to the spare tire, if the vehicle has one, even if it is never used. Multiple factors including temperatures, loading conditions, and inflation pressure maintenance affect how fast aging takes place. GM recommends that tires, including the spare if equipped, be replaced after six years, regardless of tread wear. To identify the age of a tire, use the tire manufacture date which is the last four digits of the DOT Tire

Identification Number (TIN) which is molded into one side of the tire sidewall. The first two digits represent the week (01-52) and the last two digits, the year. For example, the third week of the year

2010 would have a four-digit DOT date of 0310.

Vehicle Storage

Tires age when stored normally mounted on a parked vehicle. Park a vehicle that will be stored for at least a month in a cool, dry, clean area away from direct sunlight to slow aging. This area should be free of grease, gasoline, or other substances that can deteriorate rubber.

Parking for an extended period can cause flat spots on the tires that may result in vibrations while

Vehicle Care 399

driving. When storing a vehicle for at least a month, remove the tires or raise the vehicle to reduce the weight from the tires.

Buying New Tires

GM has developed and matched specific tires for the vehicle. The original equipment tires installed were designed to meet General

Motors Tire Performance Criteria

Specification (TPC Spec) system rating. When replacement tires are needed,

GM strongly recommends buying tires with the same TPC

Spec rating.

GM's exclusive TPC Spec system considers over a dozen critical specifications that impact the overall performance of the vehicle, including brake system performance, ride and handling, traction control, and tire pressure monitoring performance. GM's TPC Spec number is molded onto the tire's

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

400 Vehicle Care

sidewall near the tire size. If the tires have an all-season tread design, the TPC Spec number will be followed by MS for mud and snow. See

Tire Sidewall

Labeling

381

for additional information.

GM recommends replacing worn tires in complete sets of four (six for dual rear wheels). Uniform tread depth on all tires will help to maintain the performance of the vehicle. Braking and handling performance may be adversely affected if all the tires are not replaced at the same time. If proper rotation and maintenance have been done, all four tires (six for dual rear wheels) should wear out at about the same time. See

Tire

Rotation

396

for information on proper tire rotation. However, if it is necessary to replace only one axle set of worn tires, place the new tires on the rear axle

(two for single rear wheels, four for dual rear wheels).

{

Warning

Tires could explode during improper service. Attempting to mount or dismount a tire could cause injury or death.

Only your dealer or authorized tire service center should mount or dismount the tires.

{

Warning

Mixing tires of different sizes, tread patterns, or types on the same axle may cause loss of control of the vehicle, resulting in a crash or other vehicle damage. Use the same size, load range, and type of tires as the original tires.

(Continued)

Warning (Continued)

This vehicle may have a different size spare than the road tires originally installed on the vehicle. When new, the vehicle included a spare tire and wheel assembly with a similar overall diameter as the road tires and wheels, so it is all right to drive on it. The spare tire was developed for use on this vehicle and will not affect vehicle handling.

{

Warning

Using bias-ply tires on the vehicle may cause the wheel rim flanges to develop cracks after many miles of driving.

A tire and/or wheel could fail suddenly and cause a crash.

Use only radial-ply tires with the wheels on the vehicle.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

Winter tires with the same speed rating as the original equipment tires may not be available for H,

V, W, Y and ZR speed rated tires. Never exceed the winter tires ’ maximum speed capability when using winter tires with a lower speed rating.

If the vehicle tires must be replaced with a tire that does not have a TPC Spec number, make sure they are the same size, load range, speed rating, and construction (radial) as the original tires.

Vehicles that have a tire pressure monitoring system could give an inaccurate low-pressure warning if non-TPC

Spec rated tires are installed.

Different Size Tires and

Wheels

If wheels or tires are installed that are a different size than the original equipment wheels and tires, vehicle performance, including its braking, ride and handling characteristics, stability, and resistance to rollover may be affected. If the vehicle has electronic systems such as antilock brakes, rollover airbags, traction control, electronic stability control, or All-Wheel Drive, the performance of these systems can also be affected.

Uniform Tire Quality

Grading

The following information relates to the system developed by the

United States National Highway

Traffic Safety Administration

(NHTSA), which grades tires by treadwear, traction, and temperature performance. This applies only to vehicles sold in the United States. The grades are molded on the sidewalls of most passenger car tires. The

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

402 Vehicle Care

Uniform Tire Quality Grading

(UTQG) system does not apply to deep tread, winter tires, compact spare tires, tires with nominal rim diameters of

10 to 12 inches (25 to 30 cm), or to some limited-production tires.

While the tires available on

General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to federal safety requirements and additional General Motors Tire

Performance Criteria (TPC) standards.

Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example:

Treadwear 200 Traction AA

Temperature A

All Passenger Car Tires Must

Conform to Federal Safety

Requirements In Addition To

These Grades.

Treadwear

The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half (1½) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.

Traction

The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.

Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.

Temperature

The temperature grades are A

(the highest), B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19 laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade

C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Safety

Standard No. 109. Grades B and

A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.

Wheel Alignment and Tire

Balance

The tires and wheels were aligned and balanced at the factory to provide the longest tire life and best overall performance. Adjustments to wheel alignment and tire balancing are not necessary on a regular basis. Consider an alignment check if there is unusual tire wear or the vehicle is significantly pulling to one side or the other. Some slight pull to the left or right, depending on the crown of the road and/or other road surface variations such as troughs or ruts, is normal. If the vehicle is vibrating when driving on a smooth road, the tires and wheels may need to be rebalanced. See your dealer for proper diagnosis.

Wheel Replacement

Replace any wheel that is bent, cracked, or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced.

If the wheel leaks air, replace it.

Vehicle Care 403

Some aluminum wheels can be repaired. See your dealer if any of these conditions exist.

Your dealer will know the kind of wheel that is needed.

Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces.

Replace wheels, wheel bolts, wheel nuts, or Tire Pressure Monitor

System (TPMS) sensors with new

GM original equipment parts.

{

Warning

Using the wrong replacement wheels, wheel bolts, or wheel nuts can be dangerous. It could affect the braking and handling of the vehicle. Tires can lose air, and cause loss of control, causing a crash. Always use the correct wheel, wheel bolts, and wheel nuts for replacement.

404 Vehicle Care

Caution

The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance, and tire or tire chain clearance to the body and chassis.

Whenever a wheel, wheel bolt, or wheel nut is replaced on a dual wheel setup, check the wheel nut torque after 160,1 600, and

10 000 km (100,1,000, and

6,000 mi) of driving. For proper torque, see “ Wheel Nut Torque ” under

Warning

Replacing a wheel with a used one is dangerous. How it has been used or how far it has been driven may be unknown. It could fail suddenly and cause a crash.

When replacing wheels, use a new GM original equipment wheel.

Tire Chains

{

Warning

If the vehicle has LT275/65R18,

275/60R20, LT275/65R20, or 275/

50R22 size tires, do not use tire chains. If the vehicle is a 1500

Series with LT265/70R17 size tires, do not use tire chains. They can damage the vehicle because there is not enough clearance.

Tire chains used on a vehicle

(Continued)

Warning (Continued)

without the proper amount of clearance can cause damage to the brakes, suspension, or other vehicle parts. The area damaged by the tire chains could cause you to lose control of the vehicle, and you or others may be injured in a crash.

Use another type of traction device only if its manufacturer recommends it for use on the vehicle's tire size combination and road conditions. Follow that manufacturer's instructions. To help avoid damage to the vehicle, drive slowly, readjust, or remove the device if it is contacting the vehicle, and do not spin the vehicle's wheels.

If you do find traction devices that will fit, install them on the rear tires.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

Caution

Use tire chains only where legal and only when necessary. Use chains that are the proper size for the tires. If the vehicle has 265/

70R17 or 265/65R18 size tires, they may be installed on the tires of the rear axle only. If the vehicle is a dual rear wheel model and has LT235/80R17 tires, chains may be installed on the tires of the rear axle only. If the vehicle has 255/70R17, LT245/75R17, or LT275/70R18 size tires, they may be installed on the tires of the front and rear axle. If the vehicle is a 2500 Series with

LT265/70R17 size tires, chains may be installed on the tires of both the front and rear axle.

Tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer's instructions. If you can hear the

(Continued)

Caution (Continued)

chains contacting the vehicle, stop and retighten them. If the contact continues, slow down until it stops. Driving too fast or spinning the wheels with chains on will damage the vehicle.

If a Tire Goes Flat

It is unusual for a tire to blowout while driving, especially if the tires are maintained properly. If air goes out of a tire, it is much more likely to leak out slowly. But if there ever is a blowout, here are a few tips about what to expect and what to do:

If a front tire fails, the flat tire creates a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, and then gently brake to a stop, well off the road, if possible.

Vehicle Care 405

A rear blowout, particularly on a curve, acts much like a skid and may require the same correction as used in a skid. Stop pressing the accelerator pedal and steer to straighten the vehicle. It may be very bumpy and noisy. Gently brake to a stop, well off the road, if possible.

{

Warning

Driving on a flat tire will cause permanent damage to the tire.

Re-inflating a tire after it has been driven on while severely underinflated or flat may cause a blowout and a serious crash.

Never attempt to re-inflate a tire that has been driven on while severely underinflated or flat.

Have your dealer or an authorized tire service center repair or replace the flat tire as soon as possible.

434 Vehicle Care

2500/3500 Series vehicles, at least every engine oil change lubricate the upper and lower control arm ball joints. Control arm ball joints on

1500 series vehicles are maintenance-free.

2500/3500 Series vehicles equipped with steering linkage, at least every engine oil change lubricate the tie rod ball joints, idler arm pivot shaft bearings, idler arm socket, and pitman arm socket.

Caution

Lubrication of applicable suspension points should not be done unless the temperature is

− 12 °C (10 °F) or higher, or damage could result.

Body Component Lubrication

Lubricate all key lock cylinders, hood hinges, liftgate hinges, and the steel fuel door hinge unless the components are plastic. Applying silicone grease on weatherstrips with a clean cloth will make them last longer, seal better, and not stick or squeak.

Underbody Maintenance

At least twice a year, spring and fall, use plain water to flush any corrosive materials from the underbody. Take care to thoroughly clean any areas where mud and other debris can collect. If equipped with power assist steps, extend them and then use a high pressure wash to clean all joints and gaps.

Sheet Metal Damage

If the vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to parts repaired or replaced to restore corrosion protection.

Original manufacturer replacement parts will provide the corrosion protection while maintaining the vehicle warranty.

Finish Damage

Quickly repair minor chips and scratches with touch-up materials available from your dealer to avoid corrosion. Larger areas of finish damage can be corrected in your dealer's body and paint shop.

Chemical Paint Spotting

Airborne pollutants can fall upon and attack painted vehicle surfaces causing blotchy, ring-shaped discolorations, and small, irregular dark spots etched into the paint surface. Refer to “ Finish Care ” previously in this section.

Interior Care

To prevent dirt particle abrasions, regularly clean the vehicle's interior.

Immediately remove any soils.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

Newspapers or dark garments can transfer color to the vehicle ’ s interior.

Use a soft bristle brush to remove dust from knobs and crevices on the instrument cluster. Using a mild soap solution, immediately remove hand lotions, sunscreen, and insect repellent from all interior surfaces or permanent damage may result.

Use cleaners specifically designed for the surfaces being cleaned to prevent permanent damage. Apply cleaners directly to the cleaning cloth. Do not spray cleaners on any switches or controls. Remove cleaners quickly.

Before using cleaners, read and follow all safety instructions on the label. While cleaning the interior, open the doors and windows to get proper ventilation.

To prevent damage, do not clean the interior using the following cleaners or techniques:

Never use a razor or any other sharp object to remove soil from any interior surface.

Never use a brush with stiff bristles.

Never rub any surface aggressively or with too much pressure.

Do not use laundry detergents or dishwashing soaps with degreasers. For liquid cleaners, use approximately 20 drops per

3.8 L (1 gal) of water.

A concentrated soap solution will create streaks and attract dirt.

Do not use solutions that contain strong or caustic soap.

Do not heavily saturate the upholstery when cleaning.

Do not use solvents or cleaners containing solvents.

Interior Glass

To clean, use a terry cloth fabric dampened with water. Wipe droplets left behind with a clean dry cloth.

If necessary, use a commercial glass cleaner after cleaning with plain water.

Vehicle Care 435

Caution

To prevent scratching, never use abrasive cleaners on automotive glass. Abrasive cleaners or aggressive cleaning may damage the rear window defogger.

Cleaning the windshield with water during the first three to six months of ownership will reduce tendency to fog.

Speaker Covers

Vacuum around a speaker cover gently, so that the speaker will not be damaged. Clean spots with water and mild soap.

Coated Moldings

Coated moldings should be cleaned.

When lightly soiled, wipe with a sponge or soft, lint-free cloth dampened with water.

When heavily soiled, use warm soapy water.

13337620) - 2020 - CRC - 4/10/19

436 Vehicle Care

Fabric/Carpet/Suede

Start by vacuuming the surface using a soft brush attachment. If a rotating vacuum brush attachment is being used, only use it on the floor carpet. Before cleaning, gently remove as much of the soil as possible:

Gently blot liquids with a paper towel. Continue blotting until no more soil can be removed.

For solid soils, remove as much as possible prior to vacuuming.

To clean:

1. Saturate a clean, lint-free colorfast cloth with water.

Microfiber cloth is recommended to prevent lint transfer to the fabric or carpet.

2. Remove excess moisture by gently wringing until water does not drip from the cleaning cloth.

3. Start on the outside edge of the soil and gently rub toward the center. Fold the cleaning cloth to a clean area frequently to prevent forcing the soil in to the fabric.

4. Continue gently rubbing the soiled area until there is no longer any color transfer from the soil to the cleaning cloth.

5. If the soil is not completely removed, use a mild soap solution followed only by plain water.

If the soil is not completely removed, it may be necessary to use a commercial upholstery cleaner or spot lifter. Test a small hidden area for colorfastness before using a commercial upholstery cleaner or spot lifter. If ring formation occurs, clean the entire fabric or carpet.

After cleaning use a paper towel to blot excess moisture.

Cleaning High Gloss Surfaces and Vehicle Information and

Radio Displays

Use a microfiber cloth on high gloss surfaces or vehicle displays. First, use a soft bristle brush to remove dirt that can scratch the surface.

Then gently clean by rubbing with a microfiber cloth. Never use window cleaners or solvents. Periodically hand wash the microfiber cloth separately, using mild soap. Do not use bleach or fabric softener. Rinse thoroughly and air dry before next use.

Caution

Do not attach a device with a suction cup to the display. This may cause damage and would not be covered by the vehicle warranty.

448 Service and Maintenance

Additional

Maintenance and Care

Your vehicle is an important investment and caring for it properly may help to avoid future costly repairs. To maintain vehicle performance, additional maintenance services may be required.

It is recommended that your dealer perform these services — their trained dealer technicians know your vehicle best. Your dealer can also perform a thorough assessment with a multi-point inspection to recommend when your vehicle may need attention.

The following list is intended to explain the services and conditions to look for that may indicate services are required.

Battery

The 12-volt battery supplies power to start the engine and operate any additional electrical accessories.

To avoid break-down or failure to start the vehicle, maintain a battery with full cranking power.

Trained dealer technicians have the diagnostic equipment to test the battery and ensure that the connections and cables are corrosion-free.

Belts

Belts may need replacing if they squeak or show signs of cracking or splitting.

Trained dealer technicians have access to tools and equipment to inspect the belts and recommend adjustment or replacement when necessary.

Brakes

Brakes stop the vehicle and are crucial to safe driving.

Signs of brake wear may include chirping, grinding, or squealing noises, or difficulty stopping.

Trained dealer technicians have access to tools and equipment to inspect the brakes and recommend quality parts engineered for the vehicle.

Fluids

Proper fluid levels and approved fluids protect the vehicle ’ s systems and components. See

Recommended Fluids and

Lubricants

451

for GM approved fluids.

Engine oil and windshield washer fluid levels should be checked at every fuel fill.

Instrument cluster lights may come on to indicate that fluids may be low and need to be filled.

Hoses

Hoses transport fluids and should be regularly inspected to ensure that there are no cracks or leaks.

With a multi-point inspection, your dealer can inspect the hoses and advise if replacement is needed.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/2/19

Lamps

Properly working headlamps, taillamps, and brake lamps are important to see and be seen on the road.

Signs that the headlamps need attention include dimming, failure to light, cracking, or damage.

The brake lamps need to be checked periodically to ensure that they light when braking.

With a multi-point inspection, your dealer can check the lamps and note any concerns.

Shocks and Struts

Shocks and struts help aid in control for a smoother ride.

Signs of wear may include steering wheel vibration, bounce/ sway while braking, longer stopping distance, or uneven tire wear.

As part of the multi-point inspection, trained dealer technicians can visually inspect the shocks and struts for signs of leaking, blown seals, or damage, and can advise when service is needed.

Tires

Tires need to be properly inflated, rotated, and balanced. Maintaining the tires can save money and fuel, and can reduce the risk of tire failure.

Signs that the tires need to be replaced include three or more visible treadwear indicators; cord or fabric showing through the rubber; cracks or cuts in the tread or sidewall; or a bulge or split in the tire.

Trained dealer technicians can inspect and recommend the right tires. Your dealer can also provide tire/wheel balancing services to ensure smooth vehicle operation at all speeds.

Your dealer sells and services name brand tires.

Customer Satisfaction

Procedure

Your satisfaction and goodwill are important to your dealer and to

Chevrolet. Normally, any concerns with the sales transaction or the operation of the vehicle will be resolved by your dealer's sales or service departments. Sometimes, however, despite the best intentions of all concerned, misunderstandings can occur. If your concern has not been resolved to your satisfaction, the following steps should be taken:

STEP ONE :

Discuss your concern with a member of dealership management. Normally, concerns can be quickly resolved at that level.

If the matter has already been reviewed with the sales, service, or parts manager, contact the owner of your dealership or the general manager.

STEP TWO :

If after contacting a member of dealership management, it appears your concern cannot be

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

462 Customer Information

resolved by your dealership without further help, in the U.S., call the

Chevrolet Customer Assistance

Center at 1-800-222-1020. In

Canada, call General Motors of

Canada Customer Care Centre at

1-800-263-3777 (English), or 1-800-263-7854 (French).

We encourage you to call the toll-free number in order to give your inquiry prompt attention. Have the following information available to give the Customer Assistance representative:

Vehicle Identification

Number (VIN). This is available from the vehicle registration or title, or the plate at the top left of the instrument panel and visible through the windshield.

Dealership name and location.

Vehicle delivery date and present mileage.

When contacting Chevrolet, remember that your concern will likely be resolved at a dealer's facility. That is why we suggest following Step One first.

STEP THREE — U.S. Owners :

Both General Motors and your dealer are committed to making sure you are completely satisfied with your new vehicle. However, if you continue to remain unsatisfied after following the procedure outlined in Steps One and Two, you can file with the Better Business

Bureau (BBB) Auto Line Program to enforce your rights.

The BBB Auto Line Program is an out-of-court program administered by the Council of Better Business

Bureaus to settle automotive disputes regarding vehicle repairs or the interpretation of the New Vehicle

Limited Warranty. Although you may be required to resort to this informal dispute resolution program prior to filing a court action, use of the program is free of charge and your case will generally be heard within

40 days. If you do not agree with the decision given in your case, you may reject it and proceed with any other venue for relief available to you.

You may contact the BBB Auto Line

Program using the toll-free telephone number or write them at the following address:

BBB Auto Line Program

Council of Better Business Bureaus,

Inc.

Suite 600

Arlington, VA 22201

Telephone: 1-800-955-5100 http://www.bbb.org/council/ programs-services/ dispute-handling-and-resolution/ bbb-auto-line

This program is available in all

50 states and the District of

Columbia. Eligibility is limited by vehicle age, mileage, and other factors. General Motors reserves the right to change eligibility limitations and/or discontinue its participation in this program.

STEP THREE — Canadian

Owners :

In the event that you do not feel your concerns have been addressed after following the procedure outlined in Steps One

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19 and Two, General Motors of Canada

Company wants you to be aware of its participation in a no-charge

Mediation/Arbitration Program.

General Motors of Canada

Company has committed to binding arbitration of owner disputes involving factory-related vehicle service claims. The program provides for the review of the facts involved by an impartial third party arbiter, and may include an informal hearing before the arbiter. The program is designed so that the entire dispute settlement process, from the time you file your complaint to the final decision, should be completed in about 70 days. We believe our impartial program offers advantages over courts in most jurisdictions because it is informal, quick, and free of charge.

For further information concerning eligibility in the Canadian Motor

Vehicle Arbitration Plan (CAMVAP), call toll-free 1-800-207-0685, or call the General Motors Customer Care

Centre, 1-800-263-3777 (English),

Reimbursement is limited and must be supported by original receipts as well as a signed and completed rental agreement and meet state/ provincial, local, and rental vehicle provider requirements.

Requirements vary and may include minimum age requirements, insurance coverage, credit card, etc.

Additional fees such as fuel, rental vehicle insurance, taxes, levies, usage fees, excessive mileage, or rental usage beyond the completion of the repair are also your responsibility.

It may not be possible to provide a like vehicle as a courtesy rental.

Additional Program

Information

All program options, such as shuttle service, may not be available at every dealer. Contact your dealer for specific availability.

General Motors reserves the right to unilaterally modify, change, or discontinue Courtesy

Transportation at any time and to resolve all questions of claim eligibility pursuant to the terms and conditions described herein at its sole discretion.

Collision Damage Repair

If the vehicle is involved in a collision and it is damaged, have the damage repaired by a qualified technician using the proper equipment and quality replacement parts. Poorly performed collision repairs diminish the vehicle resale value, and safety performance can be compromised in subsequent collisions.

Collision Parts

Genuine GM Collision parts are new parts made with the same materials and construction methods as the parts with which the vehicle was originally built. Genuine GM

Collision parts are the best choice to ensure that the vehicle's designed appearance, durability, and safety are preserved. The use of Genuine

GM parts can help maintain the GM

New Vehicle Limited Warranty.

Recycled original equipment parts may also be used for repair. These parts are typically removed from vehicles that were total losses in prior crashes. In most cases, the parts being recycled are from undamaged sections of the vehicle.

A recycled original equipment GM part may be an acceptable choice to maintain the vehicle's originally designed appearance and safety performance; however, the history of these parts is not known. Such parts are not covered by the GM New

Vehicle Limited Warranty, and any related failures are not covered by that warranty.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

Aftermarket collision parts are also available. These are made by companies other than GM and may not have been tested for the vehicle.

As a result, these parts may fit poorly, exhibit premature durability/ corrosion problems, and may not perform properly in subsequent collisions. Aftermarket parts are not covered by the GM New Vehicle

Limited Warranty, and any vehicle failure related to such parts is not covered by that warranty.

Repair Facility

GM also recommends that you choose a collision repair facility that meets your needs before you ever need collision repairs. Your dealer may have a collision repair center with GM-trained technicians and state-of-the-art equipment, or be able to recommend a collision repair center that has GM-trained technicians and comparable equipment.

Insuring the Vehicle

Protect your investment in the GM vehicle with comprehensive and collision insurance coverage. There are significant differences in the quality of coverage afforded by various insurance policy terms.

Many insurance policies provide reduced protection to the GM vehicle by limiting compensation for damage repairs through the use of aftermarket collision parts. Some insurance companies will not specify aftermarket collision parts.

When purchasing insurance, we recommend that you ensure that the vehicle will be repaired with GM original equipment collision parts.

If such insurance coverage is not available from your current insurance carrier, consider switching to another insurance carrier.

If the vehicle is leased, the leasing company may require you to have insurance that ensures repairs with

Genuine GM Original Equipment

Manufacturer (OEM) parts or

Genuine Manufacturer replacement

Customer Information 469

parts. Read the lease carefully, as you may be charged at the end of the lease for poor quality repairs.

If a Crash Occurs

If there has been an injury, call emergency services for help. Do not leave the scene of a crash until all matters have been taken care of.

Move the vehicle only if its position puts you in danger, or you are instructed to move it by a police officer.

Give only the necessary information to police and other parties involved in the crash.

Managing the Vehicle Damage

Repair Process

In the event that the vehicle requires damage repairs, GM recommends that you take an active role in its repair. If you have a pre-determined repair facility of choice, take the vehicle there, or have it towed there.

Specify to the facility that any required replacement collision parts be original equipment parts, either new Genuine GM parts or recycled original GM parts. Remember, recycled parts will not be covered by the GM vehicle warranty.

Insurance pays the bill for the repair, but you must live with the repair.

Depending on your policy limits, your insurance company may initially value the repair using aftermarket parts. Discuss this with the repair professional, and insist on

Genuine GM parts. Remember, if the vehicle is leased, you may be obligated to have the vehicle repaired with Genuine GM parts, even if your insurance coverage does not pay the full cost.

If another party's insurance company is paying for the repairs, you are not obligated to accept a repair valuation based on that insurance company's collision policy repair limits, as you have no contractual limits with that company.

In such cases, you can have control of the repair and parts choices as long as the cost stays within reasonable limits.

Vehicle Data

Recording and

Privacy

The vehicle has a number of computers that record information about the vehicle ’ s performance and how it is driven or used. For example, the vehicle uses computer modules to monitor and control engine and transmission performance, to monitor the conditions for airbag deployment and deploy them in a crash, and, if equipped, to provide antilock braking to help the driver control the vehicle. These modules may store data to help the dealer technician service the vehicle or to help GM improve safety or features. Some modules may also store data about how the vehicle is operated, such as rate of fuel consumption or average speed. These modules may retain personal preferences, such as radio presets, seat positions, and temperature settings.

Cybersecurity

GM collects information about the use of your vehicle including operational and safety related information. We collect this information to provide, evaluate, improve, and troubleshoot our products and services and to develop new products and services.

The protection of vehicle electronics systems and customer data from unauthorized outside electronic access or control is important to

GM. GM maintains appropriate security standards, practices, guidelines and controls aimed at defending the vehicle and the vehicle service ecosystem against unauthorized electronic access, detecting possible malicious activity in related networks, and responding to suspected cybersecurity incidents in a timely, coordinated and effective manner. Security incidents could impact your safety or compromise your private data. To minimize security risks, please do not connect your vehicle electronic systems to unauthorized devices or connect

Customer Information 473

your vehicle to any unknown or untrusted networks (such as

Bluetooth, WIFI or similar technology). In the event you suspect any security incident impacting your data or the safe operation of your vehicle, please stop operating your vehicle and contact your dealer.

Event Data Recorders

This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like situations, such as an air bag deployment or hitting a road obstacle, data that will assist in understanding how a vehicle ’ s systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The

EDR in this vehicle is designed to record such data as:

How various systems in your vehicle were operating;

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

13337620) - 2020 - CRC - 4/10/19

474 Customer Information

Whether or not the driver and passenger safety belts were buckled/fastened;

How far (if at all) the driver was depressing the accelerator and/ or brake pedal; and,

How fast the vehicle was traveling.

These data can help provide a better understanding of the circumstances in which crashes and injuries occur.

Note

EDR data are recorded by your vehicle only if a non-trivial crash situation occurs; no data are recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded.

However, other parties, such as law enforcement, could combine the

EDR data with the type of personally identifying data routinely acquired during a crash investigation.

To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement, that have the special equipment, can read the information if they have access to the vehicle or the EDR.

GM will not access these data or share it with others except: with the consent of the vehicle owner or, if the vehicle is leased, with the consent of the lessee; in response to an official request by police or similar government office; as part of

GM's defense of litigation through the discovery process; or, as required by law. Data that GM collects or receives may also be used for GM research needs or may be made available to others for research purposes, where a need is shown and the data is not tied to a specific vehicle or vehicle owner.

OnStar

If the vehicle is equipped with

OnStar and has an active service plan, additional data may be collected and transmitted through the OnStar system. This includes information about the vehicle ’ s operation; collisions involving the vehicle; the use of the vehicle and its features, including infotainment; and the location and approximate

GPS speed of the vehicle. Refer to the OnStar Terms and Conditions and Privacy Statement on the

OnStar website.

Advisor.

OnStar or connected services cannot work unless the vehicle is in a place where OnStar has an agreement with a wireless service provider for service in that area. The wireless service provider must also have coverage, network capacity, reception, and technology compatible with OnStar or connected services. Service involving location information about the vehicle cannot work unless GPS signals are available, unobstructed, and compatible with the OnStar hardware. OnStar or connected services may not work if the OnStar equipment is not properly installed or it has not been properly maintained. If equipment or software is added, connected, or modified,

OnStar or connected services may not work. Other problems beyond the control of OnStar — such as hills, tall buildings, tunnels, weather, electrical system design and architecture of the vehicle, damage to the vehicle in a crash, or wireless phone network congestion or jamming — may prevent service.

Assistance after the vehicle has been off continuously for 10 days without an ignition cycle. If the vehicle has not been started for

10 days, OnStar can contact

Roadside Assistance or a locksmith to help gain access to the vehicle.

Global Positioning

System (GPS)

Obstruction of the GPS can occur in a large city with tall buildings; in parking garages; around airports; in tunnels and underpasses; or in an area with very dense trees. If GPS signals are not available, the OnStar system should still operate to call OnStar. However, OnStar could have difficulty identifying the exact location.

In emergency situations, OnStar can use the last stored GPS location to send to emergency responders.

A temporary loss of GPS can cause loss of the ability to send a

Turn-by-Turn Navigation route. The

Advisor may give a verbal route or may ask for a call back after the vehicle is driven into an open area.

Cellular and GPS Antennas

Cellular reception is required for

OnStar to send remote signals to the vehicle. Do not place items over or near the antenna to prevent blocking cellular and GPS signal reception.
