T ire chains may be used with caution. See your owner's manual for specific recommendations regarding conditions. If the vehicle is equipped with a
P265/60R17 tire size use tire chains only where legal and only when necessary. Use low profile chains that add no more than 12 mm thickness to the
tire tread and inner sidewall. Use chains that are the proper size for the tires. Install them on the tires of the rear axle. Don't use chains on the tires of
the front axle. Tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer's instructions. If
the chains contact 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.

2013 Chevrolet Municipal Vehicles Technical Manual
Vehicle load limits | 9
This information is intended for those who intend to install additional equipment to the police vehicle after it has left the factory, and for those
who will be driving and loading the vehicle with passengers and/or cargo. Two labels on your vehicle show how much weight it was designed
to carry, the Tire and Loading Information label and the Certification/Tire label. These labels are attached to your vehicle and give you the
maximum load capacity, the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for your vehicle. See "Vehicle Load
Limits" in the owner manual Index for additional loading information.
The following guidelines can help you with proper loading and load distribution when installing additional equipment on the TahoePolice
Package.
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 shorten the life of the vehicle.
Adding Equipment to Your Vehicle
Before adding accessories or equipment to your police vehicle, there are some things you need to know
• The police vehicle's maximum capacity weight (payload). The weight of your police vehicle, including a full tank of fuel but without
a driver and passengers.
• The weight of items you plan on adding to your police vehicle, like roof mounted light bar(s), push bumpers, security barrier(s), rear

• The weight and number of passengers you intend to carry in your vehicle.
• The total weight of any additional cargo you intend to carry in your vehicle.
When planning your vehicle equipment installation remember not to exceed the Gross Vehicle Weight Rating (GVWR) or the Gross Axle Weight
Rating (GAWR) of the front or rear axles. To keep the available load weight less than the vehicle capacity weight, you may need to limit the
number of passengers you carry in your vehicle or change your choice of additional equipment.
Center of Gravity (CG)
A vehicle's center of gravity is an imaginary location inside the vehicle and is a balance point for the vehicle mass as it moves down the road. The
police vehicle's center of gravity, before you add a load and passengers, is approximately midway between the center of the axles, up from the
ground to just below the front window, and between the driver and passenger. Equipment location and weight on the vehicle's center of gravity
is important to keep in mind when planning an installation. Heavy equipment should be positioned as low and as far forward in the rear load
compartment as possible. Try to mount the equipment below the bottom of the side windows. Refer to the Loading Zone chart and diagram to
help with your installation plan.
A procedure to make the necessary measurements and formulas to calculate the vehicle longitudinal, lateral and vertical position of the center
of gravity can be found in the GM Coachbuilders Manual.
Equipment required to conduct the measurements for calculating the center of gravity are:
• Weight scales of sufficient capacity to measure the vehicle weight at each wheel.
• A post type hoist or other means to safely elevate the front of the vehicle to at least an angle of 20 degrees above horizontal.
See your GM dealer to get more information about this coachbuilder procedure.
Keeping the center of gravity midway between the axles is also important to provide proper braking performance. About half the total vehicle
weight on each axle is recommended.
Weigh your vehicle after the additional equipment has been installed to determine the actual weight of your vehicle. Weigh the vehicle with a
full tank of fuel and without passengers. You may need to put a limit on how many people or other equipment you can carry inside your vehicle
after the additional equipment has been installed.

Tire chains may be used with caution. See your owner's manual for specific recommendations regarding conditions. If the vehicle is equipped with a
P265/60R17 tire size use tire chains only where legal and only when necessary. Use low profile chains that add no more than 12 mm thickness to the
tire tread and inner sidewall. Use chains that are the proper size for the tires. Install them on the tires of the rear axle. Don't use chains on the tires of
the front axle. Tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer's instructions. If
the chains contact 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.

Vehicle load limits | 21
This information is intended for those who intend to install additional equipment to the police vehicle after it has left the factory, and for those
who will be driving and loading the vehicle with passengers and/or cargo. Two labels on your vehicle show how much weight it was designed
to carry, the Tire and Loading Information label and the Certification/Tire label. These labels are attached to your vehicle and give you the
maximum load capacity, the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for your vehicle. See "Vehicle Load
Limits" in the owner manual Index for additional loading information.
The following guidelines can help you with proper loading and load distribution when installing additional equipment on the TahoePolice
Package.
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 shorten the life of the vehicle.
Adding Equipment to Your Vehicle
Before adding accessories or equipment to your police vehicle, there are some things you need to know
• The police vehicle's maximum capacity weight (payload). The weight of your police vehicle, including a full tank of fuel but without
a driver and passengers.
• The weight of items you plan on adding to your police vehicle, like roof mounted light bar(s), push bumpers, security barrier(s), rear
storage organizer, highway flares, fire extinguishers, weapons, ammunition, radios, and video equipment.
• The weight and number of passengers you intend to carry in your vehicle.
• The total weight of any additional cargo you intend to carry in your vehicle.
When planning your vehicle equipment installation remember not to exceed the Gross Vehicle Weight Rating (GVWR) or the Gross Axle Weight
Rating (GAWR) of the front or rear axles. To keep the available load weight less than the vehicle capacity weight, you may need to limit the
number of passengers you carry in your vehicle or change your choice of additional equipment.
Center of Gravity (CG)
A vehicle's center of gravity is an imaginary location inside the vehicle and is a balance point for the vehicle mass as it moves down the road. The
police vehicle's center of gravity, before you add a load and passengers, is approximately midway between the center of the axles, up from the
ground to just below the front window, and between the driver and passenger. Equipment location and weight on the vehicle's center of gravity
is important to keep in mind when planning an installation. Heavy equipment should be positioned as low and as far forward in the rear load
compartment as possible. Try to mount the equipment below the bottom of the side windows. Refer to the Loading Zone chart and diagram to
help with your installation plan.
A procedure to make the necessary measurements and formulas to calculate the vehicle longitudinal, lateral and vertical position of the center
of gravity can be found in the GM Coachbuilders Manual.
Equipment required to conduct the measurements for calculating the center of gravity are:
• Weight scales of sufficient capacity to measure the vehicle weight at each wheel.
• A post type hoist or other means to safely elevate the front of the vehicle to at least an angle of 20 degrees above horizontal.
See your GM dealer to get more information about this coachbuilder procedure.
Keeping the center of gravity midway between the axles is also important to provide proper braking performance. About half the total vehicle
weight on each axle is recommended.
Weigh your vehicle after the additional equipment has been installed to determine the actual weight of your vehicle. Weigh the vehicle with a
full tank of fuel and without passengers. You may need to put a limit on how many people or other equipment you can carry inside your vehicle
after the additional equipment has been installed.
Note: See loading zone weight chart and diagram on page 10

AUxiliary Battery Power Junction
Block and Ground Studs
An auxiliary power junction block is located within the driver’s side rear cargo
area jack stowage compartment. This junction block is split to provide two
circuits for connection to customer-furnished equipment directly to the
battery through separate 50-amp circuit breakers. These circuit breakers are
located in the breaker/relay panel forward of the instrument panel glove box.
A maximum load of 100-amps (1,200-watts) can be connected.
This junction block is connected to a coiled 5-foot (1.5 m) branch of rear body
harness and fastened near the jack. Mounting of the junction block can be at
customer-selected rear cargo area locations permitted by the branch harness
length and using customer-furnished mounting hardware.
The junction block should not be attached to the interior trim plastic
components without appropriate backing hardware to the mounting bolts.

Tire Pressure Monitor
Your vehicle is equipped with a Tire Pressure Monitor (tpm) System which warns
of low tire pressure. The tpm System on your Tahoe Police Package has a spare tire
sensor but is not programmed to read the spare tire pressure. When the spare tire
from your vehicle or an unused spare tire from another Police Package is placed in
use as a road wheel, the system will not read the presence of the new tpm sensor
and must be calibrated. Refer to your owner’s manual for additional information
on the Tire Pressure Monitor and Sensor Programming. The Special Service Package
5W4 does not have sensor in spare tire.
Wiring Provisions for 12-volt
battery power supply
Your vehicle is equipped with wiring provisions for a 12-volt battery power supply.
Refer to the following information when adding electrical system. The wiring
harness is located below the instrument panel near the center of the vehicle. The
following information describes the breaker and relay location.
The 12-volt battery power is supplied through two underhood mega fuses, one
125-amp and one 60-amp. This underhood power is fed to the breaker/relay center
via a harness that passes through the driver side front of the dash, and routed
across the instrument pane to a position forward of the glove box. The breaker/
relay center is mounted to the instrument panel structure forward of the glove
box. The center includes a plastic bracket, two relays, two 30-amp breakers and
three 50-amp mega circuit breakers.
Two 30-amp breakers supply power from the underhood 60-amp mega fuse
through the contacts of the control relays to a 12-gauge (3.0 mm2) blunt cut
wires. These two blunt cut leads are part of wire coiled under the instrument panel
near the center of the vehicle.
Each relay is operated by a 0.5 mm2 blunt cut, light or dark blue control lead
includes in a 3-foot (91 cm) loop of wire under the instrument panel.
Three 50-amp mega circuit breakers, protected by three fusible links, supply power
directly from the underhood 125-amp mega fuse through three, 10-gauge (5.0
mm2) wires. Two of the wires are routed through the body harness to a split buss
junction block to the left rear of the cargo area and secured near the jack and tools.
This 3-foot (91 cm) of coiled wires can be accessed by removing the cup holder on
the top of the trim panel. The third 10-gauge (5.0 mm2) wire is a blunt cut lead,
which is part of the 3-foot (91 cm) loop of wire coiled under the instrument panel
near the center of the vehicle.
An 8-gauge (8 mm2) ground lead is also provided and it is located under the front
passenger sill plate. It can be accessed by removing the sill plate and pulling the
loop of wire at the front of the plate, the lead is 3-feet (91 cm) long.
Blunt cut ignition control power and signal circuits are also included in the wire
coiled under the instrument panel near the center of the vehicle. They include:
• A yellow, 20-gauge (0.5 mm2) circuit, hot in ACCESSORY, RUN or RAP (Retained
Accessory Power)*
• Pink, 20-gauge (0.5 mm2) circuit, hot in Start/Run (7-amp maximum load)
• A yellow/black, 20-gauge (0.5 mm2) transmission park signal. This circuit
provides switched power when the transmission is in P (Park) and the engine is
running. The circuit is at 0-volts when the transmission is in any other position,
i.e., R (Reverse), N (Neutral), D (Drive) or M (Manual 6-1). NOTE that the circuit is
also at 12-volts with the transmission in P (Park) and the ignition is OFF. To avoid
the possibility of undesired parasitic electrical load with the ignition is OFF it is
suggested that the Park/Signal circuit be isolated by routing it through the
normally open contacts of a customer furnished ignition controlled relay.*
• A dark green/white, 20-gauge (0.5 mm2) Vehicle Speed Signal (VSS) provides
4,000 pulses per mile.
The breaker and relay center is located behind and above the instrument panel
storage compartment. Remove contents from the storage tray. Using the tab at the
back of the compartment drop the tray down gently toward the floor. You will find
the breaker/relay center above the right rear corner of the storage compartment.
* These two circuits share a 15-amp fuse. (10-amp combined maximum load)

The headlamp flashing module is activated by the application of 12 volts to a dark
green/red wire in the upfitter harness. When activated, the headlamp high beams
and the high beam instrument cluster indicator will flash alternately at 2.4 flashes
per second. When the flashing module is turned on, the module sends a signal to
the BCM which alternately flashes the stop lamps and backup lamps at the same
flash rate as the headlamps. Depressing the brake pedal will override the stop
lamp flashing and placing the transmission in Reverse will override the backup
lamps flashing.
During daylight conditions, the Daytime Running Lamps (DRL) are automatically
turned off whenever the headlamps flashing module is activated. During night
time conditions, the low beam headlamps automatically turn on while the high
beam lamps flash. Turning on the high beam headlamps manually will override
the flashing module and the high beam headlamps will operate continuously.
During night time conditions the tail lamps will turn on automatically. If Option

AIR BAGS FAQ
Can specialty vehicle equipment (e.g. radar devices, video
cameras, computers, meters, radio trees, shotguns, etc.) still be
mounted in cars with passenger side air bags?
Yes, but care must be taken to mount the equipment outside of the deployment zone.
Air bags inflate with great force and will interact with any object in the deployment
zone. Therefore, to reduce the risk of injury to vehicle occupants, GM recommends
that the air deployment zone be kept free of any equipment. If a piece of equipment
were to become dislodged it could strike an occupant in the vehicle and result in
injury. The likelihood of an object becoming dislodged is influenced by many factors,
including the proximity of the object to the inflatable restraint, the size and shape of
the object, and the means by which the object is secured to the vehicle. In addition to
these factors, the trajectory and velocity of a dislodged object can be influenced by
the type and severity of vehicle crash.
Objects that are in the deployment zone, but do not become dislodged by an inflating
air bag can still affect the performance of the air bag. For example, such objects could
tear the fabric or affect the shape of the air bag, thus reducing the ability of the bag
to provide restraint.
Is it possible to shield equipment that is installed in the passenger
side frontal air bag deployment zone in a manner that will allow
full and safe air bag deployment?
Due to the complexity of influencing variables, GM is unable to evaluate the potential
for shielding expected equipment configurations in all accident scenarios in order
to assure that the air bag performance would be unaffected. While shielding may
protect certain equipment from being damaged or dislodged, it may also negatively
affect the inflation characteristics of the air bag. The air bag’s shape, inflation angle,
fold pattern, and inflation rate and pressure are developed to maximize the
protection capability of the inflatable restraint system. Therefore, GM cannot
recommend the placement of any equipment in the deployment zone, even if it is
shielded to protect it from damage.
Front air bag systems and instrument panel mounted equipment.
Passenger air bags in GM vehicles deploy in different ways depending upon the type
of vehicle and the particular instrument panel design.
In some vehicles, the passenger air bag deploys through a discrete door located on
the top surface of the instrument panel (top-mount air bag systems). In other
vehicles, such as the Chevrolet Tahoe, the passenger air bag deploys through a
discrete door mounted on the vertical rearward surface of the instrument panel,
above the glove box door (mid-mount air bag system). With these types of topmount and mid-mount passenger air bag systems, the top pad of the instrument
panel remains in place during deployment.
Some GM passenger air bag systems, like the system in the Chevrolet Impala, deploy
from beneath the instrument panel top pad. These are considered 3/4-mount air bag
systems with a “deployable top pad.” The entire instrument panel top pad is the
“deployment door” from under which the inflating air bag emerges. When an air bag
deployment is commanded, the forces from the inflating passenger air bag push up
on the instrument panel top pad, releasing special fasteners across the rearward edge
of the top pad. This allows the top pad to rotate upward so that the passenger air bag
may emerge. The top pad rotates upward to open widest at the right hand side, and
is usually forced upward into contact with the windshield on the right hand side of
the vehicle during a deployment.
Instrument panel top mounted special equipment, such as a radar antenna and
control unit or video camera must be positioned to the left of the vehicle center line.
This equipment must be mounted as low as possible and securely fastened to the top
pad to avoid being dislodged in the event of a crash and possible air bag deployment.
In the process of securely fastening special equipment to the top, DO NOT fasten
down the top pad itself to any other vehicle component such as the cluster trim plate.
As described above, the top pad rotates upward during a deployment. In order to
enable the proper deployment of the passenger air bag, specialty equipment
installation MUST NOT PREVENT the top pad from rotating upward during
deployment. Location and attachment of special equipment should minimize added
resistance or interference to upward rotation of the top pad during deployment.
Side air bags for crashes to the vehicle sides.
The air bag system in your police vehicle includes roof rail mounted side air bags. The
vehicle is also equipped with seat back mounted upper body air bags located on the
outboard side of the driver and front passenger seat backs. Together the roof rail and
seat back air bags are intended to protect the head and upper body in the event of a
side crash. Some vehicles may also be equipped with an optional air bag, mounted on
the inboard side of the driver seat back.
Can Specialty Vehicle Security Barriers be mounted within the side
air bag deployment zones?
No. The side air bags inflate extremely fast because of the nature of side crashes to
the vehicle. Mounting a security barrier behind the front seats with the ends placed
within the side air bag deployment zones will result in unintended interaction
between the barrier and the inflating side air bags. To reduce the risk of injury to the
vehicle occupants, GM recommends that the side air bag zones be kept free of any
customer installed equipment.
Customer furnished equipment installed to the vehicle roof.
Your police vehicle is designed with an interior roof cover system which includes
internal components for the interior lamps and wiring. The roof system may also
include side air bag components. Inflation devices may be mounted on the vehicle
roof side behind the rear doors as well as air bag tethers retained to the
windshield pillars. Care must be taken to avoid damage to these components
or interference with their operation when installing roof mounted equipment such
as emergency lamps and communication antennas.
Recommended GM service procedures must be followed to remove
and re-install the instrument panel top pad to ensure that the top
pad will release properly in the event of a passenger air bag
deployment.
On the right half of the top pad closest to the passenger air bag module,
GM recommends that no equipment be mounted. When mounting equipment on the
driver side of the top pad, GM recommends that the total mass of the top pad
mounted special equipment not exceed 8 pounds (3.6 kilograms), since some top
pads tend to rotate about the left end.
Fasteners used to secure special equipment to the instrument panel top pad, the
windshield glass, or to the windshield upper frame (header), should be selected to
ensure that these devices will remain attached during a vehicle crash and possible
air bag deployment.

AIR BAGS FAQ
| 33
Can the installation of push bumpers on the front end of the vehicle
affect the deployment of the air bag?
I've heard that a deployed air bag produces whet appears to be
smoke, is the air bag hot?
General Motors is not aware of adverse effects during crash events from the many
push bumpers thai have been installed on GM police vehicles. Because there are many
styles of push bumpers available with varying crash characteristics, installation of
push bumpers may or may not affect deployment timing of the air bags. Push
bumpers should be mounted to avoid modifying the vehicle structure and interfering
with the front air bag sensors mounted on the upper radiator support cross member
After the bag has deployed in a crash, the air bag itself will not be hot to touch. Some
components within the air bag module will be hot for a short time. A small amount of
smoke coming from a deployed air bag module is normal and should not be cause for
concern.
Two front impad sensors are installed in General Motors vehicles. Do not relocate or
disconnect the front sensors. The location and orientation of the front sensors are
critical for correct operation of the air bag system. Avoid mounting components on or
near the sensors. Push bumper styles with vertical pushing members that are in
foreaft alignment with the front air bag sensors are not recommended.
When should an air bag inflate?
The driver's and right-front passenger's frontal air bags are designed to inflate in
moderate to severe frontal or near-frontal crashes. But they are designed to inflate
only if the impact speed is above the system's designed "threshold level."
In addition, your vehicle has “dual stage” frontal air bags which tailor the the amount
of restraint according to crash severity. For moderate frontal impacts, the air bags
inflate at a level less than full deployment. For more severe frontal impacts, "dual
stage" frontal air bags deploy at full levels.
If the front of your vehicle goes straight into a wall that doesn't move or deform, the
threshold level of the reduced deployment is about 12 to 16mph (19 to 15 km/h), and
the threshold level for a full deployment is about 18 to 24 mph (29 to 28.5 km/h). The
threshold level can vary, however, with specific vehicle design, so that it can be
somewhat above or below this range.
If your vehicle strikes something that will move or deform such as a parked car, the
threshold level will be higher. The driver's and right-front passenger's frontal air bags
are not designed to inflate in rollover, side impacts, or rear impacts, because inflation
would not help the occupant.
Seat mounted side impact air bags are designed to inflate in moderate to severe side
crashes. The side impact air bags will inflate if the crash severity is above the designed
"threshold level." The threshold level can vary with specific vehicles design. The side
impact air bags are not designed to inflate on frontal or near-frontal impacts or rear
impacts, because inflation would not help the occupant.
Also, when the nitrogen gas is vented out of the air bag, small particles from inside
the bag are also vented into passenger compartment. These airborne particles look
like smoke and some particles are deposited as residue on and around the air bag.
I've heard that the dusts that are released into the passenger
compartment from the air bag are harmful, is this true?
For most people, the only effect the dusts will produce is some irritation of the throat
and eyes, and that is only if the occupant remains in the vehicle for many minutes
after the air bag deployment with no ventilation and windows closed. However, some
people with asthma may develop an asthmatic attack from inhaling the dusts. If this
happens, they should first treat themselves the same way their doctor has advised
them to treat any other asthma attack, and then immediately seek medical
treatment.
Can the air bag system be re-used?
No, The air bags are designed to inflate only once. After inflation some new parts will
be required. These will include the air bag module and possibly other parts. (A
competent service technician with access to the vehicle's service manual and the
required tools should replace the required components after a deployment crash.)
If my vehicle has air bags, why should I have to wear my safety
belt?
Air bags are in many vehicles today and will be in most of them in the future. But
they are supplemental systems only; so they work with safety belts not instead of
them. Every air bag system ever offered for sale has required the use of safety belts.
Even if you're in a vehicle that has air bags, you still have to buckle up to get the most
protection. That's true not only in frontal collisions but especially in side and other
collisions.
Roof rail mounted head-curtain air bags are designed to inflate in moderate to severe
side crashes. In addition, certain vehicles have head-curtain air bags which are also
designed to inflate in situations where an impending rollover condition is identified
by the vehicle's rollover sensing system and/or frontal or near-frontal impacts if the
crash severity is above the designed "threshold level".
Safety belt pretensioners at the driver and front passenger seat positions are designed
to deploy in frontal, near-frontal, side, and rear crashes that exceed the "threshold
level" of crash severity to help reduce slack in the safety belt Safety belt pretensioners
will also deploy in impending rollover situations.
How long will the air bag remain inflated?
It takes approximately 1/20th of a second to fully inflate the frontal air bags. This is
faster than the blink of an eye. The air bags begin to deflate immediately, helping to
stop the occupants more gradually.

Anti-lock braking system FAQ | 37
GM offers Anti-Lock Brake Systems as standard or optional
on all North American passenger vehicles and light truck
lines. The computerized Anti-Lock Braking System (ABS) is
designed to keep the vehicle’s wheels rotating as the brakes are
applied to assist the driver in achieving a controlled stop.
Sensors monitor how fast the wheels rotate and feed the data
continuously to the ABS computer. The vehicle’s brakes slow
each wheel as the brake pedal is applied. However, when
ABS is activated due to road conditions, the system repeatedly
releases and applies pressure to the brakes. The wheels
can keep rolling, thus retaining steering ability and enhanced
stability while providing a higher braking force on most
surfaces than a locked wheel provides.
How exactly does ABS work?
In cars without ABS, hitting the brakes can cause the wheels to lock, leaving you unable
to steer the vehicle until you decrease the pressure so the wheels can roll again. With
an ABS, as you apply the brakes, the ABS computer monitors the wheel speed sensor
information. If the computer senses that a wheel is approaching lock up, it sends a
signal to the hydraulic modulator to reduce, then to reapply, brake pressure several
times a second for as long as you maintain firm pressure on the brake pedal. The
process is much like the threshold braking technique used with conventional brakes.
However, ABS does it much faster and more accurately than any driver can, leaving you
free to focus on steering away from obstacles.
Does ABS reduce stopping distances?
Should I drive an ABS equipped vehicle differently than
I would drive a vehicle with conventional brakes?
Most of the time, under normal driving circumstances, there is no difference,
and you should always drive with the same caution and care. It is important to realize
that ABS only makes a difference when it is activated—when you have
to brake hard—and that would only be when the computer senses that a wheel is
approaching lockup. When ABS activates, keep steady pressure on the brake pedal and
then let the ABS work for you. Don’t pump the brakes or try to ­find the threshold.
Simply hold the brake pedal down and steer if necessary to avoid an obstacle.
Is ABS always active?
ABS is always available, but not always activated. ABS is activated only when the brake
pedal is applied and the computer detects an impending wheel lock condition.
Can older cars be retrofitted with ABS?
No! The brake system is one of the most important features on any passenger vehicle.
Several products, which tap into the master cylinder and/or brake system performance,
are being sold in the aftermarket. Some of these products imply performance similar to
new vehicle anti-lock brake systems.
However, contrary to their claims, add-on systems, which deplete fluid from the master
cylinder on brake apply may actually increase a vehicle’s stopping distance. This may
cause the vehicle to fail to comply with Federal brake standards.
Does ABS always activate at the same speed?
No, the system operates when the computer detects wheel lockup, at any speed above
8 mph.
Yes, in braking situations where the wheels on a non-ABS equipped vehicle
would lock up, ABS will generally provide shorter controlled stopping distance. The
amount of improvement in stopping distance depends on many factors, including the
road surface, severity of braking, initial vehicle speed, etc. On some surfaces, such as
gravel roads, braking distances can be longer, but you will still have the control benefits
of ABS. The important capability of ABS is control. ABS provides improved vehicle
steerability and stability when braking.
Will ABS wear out a vehicle’s brakes sooner?
What can affect the ABS advantage?
Do Federal Safety Standards mandate ABS?
It is important that you follow the maintenance schedule recommended in the owner’s
manual of the vehicle, tires should be at their proper inflation level, the brake pads
should be checked regularly, etc. While driving, you should sit comfortably, so that your
hips are back in the seat and your knees are bent, even while braking. Your foot should
be positioned so that your heel is on the floor and your toes are secure on the lower half
of the pedal. And, though ABS may reduce stopping distance, remember: The faster you
go, the longer it takes you to stop. Keeping a safe distance between you and the
vehicle in front of you is always necessary, even with ABS.
A properly maintained brake system will be unaffected by ABS operation under typical
driving conditions.
Are there different types of ABS?
Yes, there are rear wheel anti-lock systems (RWAL) used on some trucks and four-wheel
ABS available on cars and trucks.
No. Federal standards establish minimum braking performance requirements that all
vehicles must meet, but do not specify how they should be met. It should be noted that
even a vehicle with failed ABS meets the Federal safety standard for stopping distances.
Will a tire size change affect ABS?
Use of tires other than original equipment may affect ABS performance. Owners should
consult and follow the recommendations contained in the vehicle owner’s manual
regarding replacement tire size. NOTE: ABS will work with original equipment spare tire or tire
What happens if ABS becomes inactive?
chains. However, performance is reduced.
The ABS electronic control unit has on-board diagnostic capability. If a fault is detected,
the vehicle will revert to the base brake system, and the ABS telltale on the dash will be
illuminated. Should this happen, the vehicle should be taken to a dealership for repair
as soon as possible.
Do insurance companies give a discount for ABS?
How do I use ABS?
Depress and hold the pedal. DO NOT PUMP THE BRAKES (that prevents the system from
working). Just hold the brake pedal down and let the ABS work for you. You may feel
the brake pedal vibrate, or you may notice some noise, but this is normal as the system
works for you.
Yes, many insurance companies give discounts that range from 5% to 10%. In the
states of New York and Florida all insurance companies are required to give an ABS
discount of 5% on certain coverages such as bodily injury, property damage, collision,
and personal injury protection. In other states the discount varies from insurance
company to insurance company. When buying auto insurance, always ask your
insurance agent if his/her company gives a discount for vehicles equipped with antilock brakes.

IMPORTANT
DRIVING
SAFETY TIPS
A. A lways maintain a safe
following distance. ABS does not
allow you to stop on a dime. (Generally a
2-second following distance is considered
safe in ideal conditions.) Watch the vehicle
in front of you pass a fixed marker (such as a
sign). Count seconds—one-thousand-one,
one-thousand-two-until your front bumper
reaches the marker. If you do not count out
two seconds, then you are too close to the
vehicle in front of you. Also, if the roads are
wet or icy, or visibility is poor, you should
increase your following distance.
B. A lways drive carefully—
especially on slippery surfaces. ABS cannot
create friction between the tires and the road
surface, it can only give the driver the
maximum advantage of the existing
adhesion. If the vehicle is traveling on a
surface with no adhesion, the best ABS in the
world cannot provide a shorter stopping
distance or good steering.
C. It is a good idea to practice an
ABS activated stop and get the feel
of the brake pedal. However, please make
sure it’s at a safe time with no obstacles in
your path. And you only really need to try
it once or twice to know what happens.
