Useful information i This Operator's Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator's
Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safetyrelated systems and functions.
i Read the information on qualified specialist workshops: ( Y page 24).
After 1,000 miles (1,500 km), you can increase the engine speed gradually and accelerate the vehicle to full speed.
Additional breaking-in notes for AMG vehicles:
R Do not drive faster than 85 mph
(140 km/h) for the first 1000 miles
(1500 km).
R
Only allow the engine to reach a maximum engine speed of 4500 rpm briefly.
R
Change gear in good time.
i You should also observe these notes on running in if the engine or parts of the drive train on your vehicle have been replaced.
i Always observe the respective speed limits.
Breaking-in notes
Important safety notes
New and replaced brake pads and discs only reach their optimum braking effect after several hundred kilometers of driving.
Compensate for this by applying greater force to the brake pedal.
The first 1,000 miles (1,500 km)
The more you look after the engine when it is new, the more satisfied you will be with its performance in the future.
R You should therefore drive at varying vehicle and engine speeds for the first
1,000 miles (1,500 km).
R
Avoid heavy loads, e.g. driving at full throttle, during this period.
R
Change gear in good time, before the tachometer needle is Ô of the way to the red area of the tachometer.
R
Do not manually shift to a lower gear to brake the vehicle.
R
If possible, do not depress the accelerator pedal past the point of resistance
(kickdown).
R Only select shift ranges 3, 2 or 1 when driving slowly, e.g. in mountainous terrain.
AMG vehicles with rear axle locking differential
Your vehicle is equipped with a self-locking differential on the rear axle. To improve the protection of the differential on the rear axle, change the oil after a break-in distance of
2,000 miles (3,000 km). This oil change extends the service life of the differential.
Have the oil change carried out at a qualified specialist workshop.

Important safety notes
G WARNING
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious personal injury.
Never allow sparks, flames or smoking materials near gasoline.
Turn off the engine before refueling.
Whenever you are around gasoline, avoid inhaling fumes and any skin or clothing contact.
Direct skin contact with fuels and the inhalation of fuel vapors are damaging to your health.
G WARNING
Overfilling of the fuel tank may create pressure in the system which could cause a gas discharge. This could cause the gasoline to spray back out when removing the fuel pump nozzle, which could cause personal injury.
! Do not use diesel to refuel vehicles with a gasoline engine. Even small amounts of the wrong fuel result in damage to the fuel system and engine.
! Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel lines.
Notify a qualified specialist workshop and have the fuel tank and fuel lines drained completely.
! Overfilling the fuel tank could damage the fuel system.
! Take care not to spill any fuel on painted surfaces. You could otherwise damage the paintwork.
! Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection system could be blocked by particles from the fuel can.

Driving tips
Fuel consumption also increases when driving in cold weather, in stop-and-go traffic and in mountainous terrain.
Drinking and driving
G WARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can affect your reflexes, perceptions and judgment.
The possibility of a serious or even fatal accident are greatly increased when you drink or take drugs and drive.
Do not drink or take drugs and drive or allow anyone to drive who has been drinking or taking drugs.
Pedals
G WARNING
Make sure absolutely no objects are obstructing the pedals' range of movement.
Keep the driver's footwell clear of all obstacles. If there are any floormats or carpets in the footwell, make sure that the pedals still have sufficient clearance.
During sudden driving or braking maneuvers, the objects could get caught between the pedals. You could then no longer brake or accelerate. This could lead to accidents and injury.
Exhaust check
G WARNING
Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide (CO), and inhaling it can cause unconsciousness and possible death.
Do not run the engine in confined areas (such as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are entering the vehicle while driving, have the cause determined and corrected immediately. If you must drive under these conditions, drive only with at least one window fully open at all times.
Certain engine systems are designed to keep the level of poisonous components in exhaust fumes within legal limits.
These systems only work at peak efficiency if they are serviced exactly in accordance with the manufacturer's specifications. Only have work on the engine carried out by qualified and authorized Mercedes-Benz technicians.
The engine settings must not be changed under any circumstances. Furthermore, all specific service work must be carried out at regular intervals and in accordance with the
Mercedes-Benz service requirements. Details can be found in the Maintenance Booklet.
ECO display
Rolling with the engine switched off
G WARNING
There is no power assistance for the steering and the brake when the engine is not running.
Steering and braking requires significantly more effort and you could lose control of the vehicle and cause an accident as a result.
Do not turn off the engine while the vehicle is in motion.
Example: ECO display
The ECO display gives you information on how economical your driving style is. The ECO display assists you in achieving the optimum driving style in terms of consumption, taking the actual and selected conditions into consideration. Your driving style can
Driving tips
161 significantly influence the vehicle's consumption.
The ECO display consists of three bars:
R
Acceleration
R Constant
R
Coasting
The percent value is the average value of the three bars. The three bars and the mean value begin at the value of 50%. A higher percentage indicates a more economical driving style.
The ECO display does not provide any information on the actual consumption. A fixed percentage count in the ECO display does not indicate a fixed consumption figure in l/100 km.
Apart from driving style, consumption is dependent on many factors such as, e.g.:
R Load
R
Tire pressure
R Cold start
R
Choice of route
R Electrical consumers switched on
These factors are not taken into consideration by the ECO display.
The evaluation of your driving style is carried out using the following three categories:
Acceleration (evaluation of all acceleration)
The bar fills up:
Moderate acceleration, especially at high speeds
The bar empties:
Sporty acceleration
Constant (evaluation of driving style at any time)

Braking
Important safety notes
G WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking effect, the drive wheels could lose their grip.
There is an increased danger of skidding and accidents.
Do not shift down for additional engine braking on a slippery road surface.
Heavy and light loads
G WARNING
If you rest your foot on the brake pedal while driving, the braking system can overheat. This increases the stopping distance and can even cause the braking system to fail. There is a risk of an accident.
Never use the brake pedal as a footrest. Never depress the brake pedal and the accelerator pedal at the same time.
! Depressing the brake pedal constantly results in excessive and premature wear to the brake pads.
If the brakes have been subjected to a heavy load, do not stop the vehicle immediately, but drive on for a short while. This allows the airflow to cool the brakes more quickly.
Wet roads
If you have driven for a long time in heavy rain without braking, there may be a delayed reaction from the brakes when braking for the first time. This may also occur after the vehicle has been washed or driven through deep water.
You have to depress the brake pedal more firmly. Maintain a greater distance from the vehicle in front.
After driving on a wet road or having the vehicle washed, brake firmly while paying attention to the traffic conditions. This will warm up the brake discs, thereby drying them more quickly and protecting them against corrosion.
Downhill gradients
! On long and steep gradients, you must reduce the load on the brakes by shifting early to a lower gear. This allows you to take advantage of the engine braking effect and helps avoid overheating and excessive wear of the brakes.
When you take advantage of the engine braking effect, a drive wheel may not turn for some time, e.g. on a slippery road surface. This could cause damage to the drive train. This type of damage is not covered by the Mercedes-Benz warranty.
Limited braking performance on salttreated roads
If you drive on salted roads, a layer of salt residue may form on the brake discs and brake pads. This can result in a significantly longer braking distance.
R
Brake occasionally to remove any possible salt residue. Make sure that you do not endanger other road users when doing so.
R
Carefully depress the brake pedal and the beginning and end of a journey.
R
Maintain a greater distance to the vehicle ahead.
Servicing the brakes
G WARNING
If brake pads or brake fluid other than those recommended are used, the braking properties of the vehicle can be degraded to an extent that safe braking is substantially impaired. This could result in an accident.
G WARNING
Make sure that you do not endanger other road users when you apply the brakes.
! If the red brake warning lamp lights up in the instrument cluster and you hear a
Driving tips
163 warning tone while the engine is running, the brake fluid level may be too low.
Observe additional warning messages in the multifunction display.
The brake fluid level may be too low due to brake pad wear or leaking brake lines.
Have the brake system checked immediately. This work should be carried out at a qualified specialist workshop.
! Vehicles with 4MATIC: function or performance tests may only be carried out on a 2-axle dynamometer. If you are planning to have the vehicle tested on such a dynamometer, contact an authorized
Mercedes-Benz Center to obtain further information first. Otherwise, you could damage the drive train or the brake system.
! Vehicles with 4MATIC: as the ESP ® system operates automatically, the engine and the ignition must be switched off

! Vehicles with 4MATIC: as the ESP ® system operates automatically, the engine and the ignition system must be switched off (SmartKey in position 0 or 1 in the ignition lock or Start/Stop button in position 0 or 1) when:
R testing the parking brake on a brake dynamometer.
R you intend to have the vehicle towed with one of the axles raised.
Braking maneuvers triggered automatically by ESP ® may seriously damage the brake system.
All checks and maintenance work on the brake system must be carried out at a qualified specialist workshop. Consult a qualified specialist workshop to arrange this.
Have brake pads installed and brake fluid replaced at a qualified specialist workshop.
If the brake system has only been subject to moderate loads, you should test the functionality of your brakes at regular intervals. To do so, press firmly on the brake pedal when driving at a high speed. This improves the grip of the brake pads.
You can find a description of Brake Assist
(BAS) on ( Y page 64) or of BAS PLUS on
( Y page 65).
AMG high-performance and ceramic brakes
The high-performance brake system is installed only on the CLS 63 AMG.
The AMG brake systems are designed for heavy loads. This may lead to noise when braking. This will depend on:
R speed
R braking force
R environmental conditions, such as temperature and humidity
The wear of individual components of the brake system, such as the brake pads/linings or brake discs, depends on the individual driving style and operating conditions.
For this reason, it is impossible to state a mileage that will be valid under all circumstances. An aggressive driving style will lead to high wear. You can obtain further information about this from your authorized
Mercedes-Benz Center.
New and replaced brake pads and discs only reach their optimum braking effect after several hundred kilometers of driving.
Compensate for this by applying greater force to the brake pedal. Keep this in mind, and adapt your driving and braking accordingly during this break-in period.
Excessive heavy braking results in correspondingly high brake wear. Observe the brake system warning lamp in the instrument cluster and note any brake status messages in the multifunction display. For

Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth on the road surface, there is a danger of hydroplaning occurring, even if:
R you drive at low speeds.
R the tires have adequate tread depth.
For this reason, in the event of heavy rain or in conditions in which hydroplaning may occur, you must drive in the following manner:
R lower your speed.
R avoid ruts.
R brake carefully.
Driving on flooded roads
! Do not drive through flooded areas.
Check the depth of any water before driving through it. Drive slowly through standing water. Otherwise, water may enter the vehicle interior or the engine compartment.
This can damage the electronic components in the engine or the automatic transmission. Water can also be drawn in by the engine's air suction nozzles and this can cause engine damage.

DISTRONIC PLUS
Important safety notes
G WARNING
The DISTRONIC PLUS requires familiarity with its operational characteristics. We strongly recommend that you review the following information carefully before operating the system.
G WARNING
The DISTRONIC PLUS is a convenience system. Its speed adjustment reduction capability is intended to make cruise control more effective and usable when traffic speeds vary. It is not however, intended to, nor does it, replace the need for extreme care.
The responsibility for the vehicle's speed, distance to the preceding vehicle and, most importantly, brake operation to ensure a safe stopping distance, always remains with the driver.
The DISTRONIC PLUS cannot take street and traffic conditions into account.
Complex driving situations are not always fully recognized by the DISTRONIC PLUS. This
Z
168
Driving systems could result in wrong or missing distance warnings.
G WARNING
DISTRONIC PLUS distance is not a substitute for the active intervention of the driver. It does not detect pedestrians or stationary objects, nor can it detect, recognize or predict the road's course or the movements of vehicles in front. DISTRONIC PLUS can only brake the vehicle using 40% of the vehicle's maximum available brake force.
DISTRONIC PLUS may not detect narrow vehicles driving in front, e.g. motorcycles, or vehicles driving in the lane beyond the lane next to your vehicle, especially if the vehicles are not driving on the middle of their lane.
The driver must always pay careful attention to the road, weather and traffic conditions.
The driver must drive, steer and brake in a manner which will allow him to always have control of the vehicle.
Sources of high-frequency radio waves, such as toll stations, speed-measuring radar, etc., can cause DISTRONIC PLUS to fail temporarily.
G WARNING
The DISTRONIC PLUS cannot take road and traffic conditions into account. Only use the
DISTRONIC PLUS if the road, weather and traffic conditions make it advisable to travel at a constant speed.
G WARNING
Use of the DISTRONIC PLUS can be dangerous on slippery roads. Rapid changes in tire traction can result in wheel spin and loss of control.
The DISTRONIC PLUS does not function in adverse sight and distance conditions. Do not use the DISTRONIC PLUS during conditions of fog, heavy rain, snow or sleet.
G WARNING
The DISTRONIC PLUS cannot take weather conditions into account. Switch off the
DISTRONIC PLUS or do not switch it on if:
R roads are slippery or covered with snow or ice. The wheels could lose traction while braking or accelerating, and the vehicle could skid.
R the DISTRONIC PLUS system sensor covers are dirty or visibility is diminished due to snow, rain or fog, for example. The distance control system functionality could be impaired.
Always pay attention to surrounding traffic conditions even while the DISTRONIC PLUS is switched on. Otherwise, you may not be able to recognize dangerous situations until it is too late. This could cause an accident in which you and/or others could be injured.
G WARNING
The "Resume" function should only be operated if the driver is fully aware of the previously set speed and wishes to resume this particular preset speed.
G WARNING
Your undivided attention to street and traffic conditions is necessary at all times whether
DISTRONIC PLUS is active or not.
The use of DISTRONIC PLUS can be dangerous on winding roads or in heavy traffic because conditions do not allow safe driving at a constant speed.
DISTRONIC PLUS does not react to stationary objects on the road (for example, a vehicle stopped in traffic or an abandoned vehicle).
DISTRONIC PLUS likewise does not react to oncoming vehicles.
Driving systems
169
Deactivate DISTRONIC PLUS:
R when changing to the right lane, if the vehicles in the left lane are driving slower
R when driving into a filter lane or an expressway exit
R in complex driving situations, for example in construction sites on an expressway
In these situations DISTRONIC PLUS will maintain the set speed if it is not deactivated.
DISTRONIC PLUS is intended only for maintaining a set speed and a set distance from the objects moving in front of the vehicle.
G WARNING
An intermittent warning sounds and the distance warning lamp · in the instrument cluster is illuminated if the DISTRONIC PLUS system calculates that the distance to the vehicle ahead and your vehicle's current speed indicate that the DISTRONIC PLUS will not be capable of slowing the vehicle sufficiently to maintain the preset following distance, which creates a danger of a collision.
Immediately brake the vehicle to increase your distance to the preceding vehicle. The warning sound is intended as a final caution in which you should intercede with your own braking inputs to avoid a potentially dangerous situation. Do not wait for the operation of the warning signal to intercede with your own braking. This will result in potentially dangerous emergency braking which will not always result in an impact being avoided.
Tailgating increases the risk of an accident.
G WARNING
DISTRONIC PLUS brakes your vehicle with a maximum deceleration of 13 ft/s 2 (4 m/s 2 ).
This corresponds to approximately 40% of your vehicle's maximum braking force.
To avoid a collision, you must apply the brakes yourself. DISTRONIC PLUS brakes the vehicle just enough to restore the preset speed or the preset distance to the vehicle in front.
G WARNING
If you do not receive visual or acoustic warning signals during a critical traffic situation, DISTRONIC PLUS has either not recognized the collision risk, has been deactivated or is malfunctioning.
Remember, whether or not DISTRONIC PLUS is operating, it is ultimately always the drivers responsibility to apply the brakes in order to control the vehicle and avoid a collision.
General notes
DISTRONIC PLUS regulates the speed and automatically helps you maintain the distance to the vehicle detected in front.
DISTRONIC PLUS brakes automatically so that the set speed is not exceeded.
If DISTRONIC PLUS detects a slower-moving vehicle in front, your vehicle is braked in order to maintain the preset distance to the vehicle in front.
If you want DISTRONIC PLUS to assist you, the radar sensor system must be activated
( Y page 223) and operational.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise control in the speed range between 20 mph
(Canada: 30 km/h) and120 mph (Canada:
200 km/h). If a vehicle is driving in front of you, it operates in the speed range between
0 mph (0 km/h) and 120 mph (Canada:
200 km/h).
Do not use DISTRONIC PLUS while driving on roads with steep gradients.
As DISTRONIC PLUS transmits radar waves, it can resemble the radar detectors of the responsible authorities. You can refer to the relevant chapter in the Operator's Manual if questions are asked about this.

R you are driving faster than 40mph
(60 km/h).
R
DISTRONIC PLUS is maintaining the distance to a vehicle in front.
R you switch on the appropriate turn signal.
R DISTRONIC PLUS does not detect a danger of collision.
If these conditions are fulfilled, your vehicle is accelerated. Acceleration will be interrupted if changing lanes takes too long or if the distance between your vehicle and the vehicle in front becomes too small.
i When changing lanes, DISTRONIC PLUS monitors the left lane on left-hand drive vehicles and the right lane on right-hand drive vehicles.
Vehicles with COMAND i The following function is not operational in all countries.
DISTRONIC PLUS uses additional information from your navigation system so that it can react appropriately to certain traffic situations. This is the case if, while following a vehicle, DISTRONIC PLUS is active and you:
R approach or drive through a traffic circle
R approach a T-intersection
R turn off at a freeway exit
Even if the vehicle in front leaves the detection range, DISTRONIC PLUS temporarily maintains the current driving speed and does not accelerate. This is based on the current map data in the navigation system.
Example: traffic circle
The current speed is maintained:
R approximately ten seconds before the traffic circle/T-intersection and for approximately 1.5seconds when driving on the traffic circle
R approximately twelve seconds before reaching a freeway exit and approximately four seconds after the freeway exit
Afterwards, the vehicle accelerates back to the set speed you specified.

Tips for driving with DISTRONIC PLUS
Important safety notes
G WARNING
The DISTRONIC PLUS works to maintain the speed selected by the driver unless a moving obstacle proceeding directly ahead of it in the same travel direction is detected (e.g.
following another vehicle ahead of you at your set distance).
This means that:
R Your vehicle can pass another vehicle after you have changed lanes.
R While in a sharp turn or if the preceding vehicle is in a sharp turn, the DISTRONIC
PLUS could lose sight of the preceding vehicle. Your vehicle could then accelerate to the previously selected speed.
Driving systems
177
The DISTRONIC PLUS regulates only the distance between your vehicle and those directly ahead of it. It may not register stationary objects in the road, e.g.:
R a stopped vehicle in a traffic jam
R a disabled vehicle
R an oncoming vehicle
The driver must always be alert, observe all traffic and intercede as required by means of steering or braking the vehicle.
G WARNING
The DISTRONIC PLUS should not be used in snowy or icy road conditions.
The following contains descriptions of certain road and traffic conditions in which you must be particularly attentive. In such situations, brake if necessary. DISTRONIC PLUS is then deactivated.
Cornering, going into and coming out of a bend
Vehicles traveling on a different line
DISTRONIC PLUS may not detect vehicles traveling on a different line. The distance to the vehicle in front will be too short.
Other vehicles changing lanes
DISTRONIC PLUS has not detected the vehicle cutting in yet. The distance to this vehicle will be too short.
Narrow vehicles
The ability of DISTRONIC PLUS to detect vehicles when cornering is limited. Your vehicle may brake unexpectedly or late.
DISTRONIC PLUS has not yet detected the vehicle in front on the edge of the road,
Z
178
Driving systems because of its narrow width. The distance to the vehicle in front will be too short.

Active Parking Assist
Important safety notes
G WARNING
Active Parking Assist is merely an aid and may sometimes recommend parking spaces that are not suitable for parking. For example, these might be spaces where parking is prohibited, driveways, unsuitable surfaces, etc.
Active Parking Assist measures the parking space as you drive past it. Any later changes to the parking space are not taken into account. For instance, this may be the case when the vehicle parked in front of or behind the space changes its position or when an obstacle is moved into the parking space.
Active Parking Assist does not relieve you of the responsibility of paying attention. If you rely solely on Active Parking Assist, you could cause an accident and injure yourself and others.
You are always responsible for safety and must continue to pay attention to your immediate surroundings when parking and maneuvering.
G WARNING
Objects located above the height range of
Active Parking Assist will not be detected when the parking space is measured. These are not taken into account when the parking procedure is calculated, e.g. overhanging loads, tail sections or loading ramps of goods vehicles. In some circumstances, Active
Parking Assist may therefore guide you into the parking space too early. This may lead to a collision. For this reason, you should avoid using Active Parking Assist in such situations.
Driving systems
187
G WARNING
The front of the vehicle will veer out in the direction of the oncoming traffic during the parking operation. In some cases, the vehicle will also take you onto sections of the oncoming lane during the parking procedure.
You are responsible for safety at all times and must pay attention to any road users approaching or passing. Stop the vehicle if necessary or cancel the Active Parking Assist parking procedure.
G WARNING
Make sure no persons or animals are in or near the area in which you are parking/ maneuvering. Otherwise, they could be injured.
! If unavoidable, you should drive over obstacles such as curbs slowly and not at a sharp angle. Otherwise, you may damage the wheels or tires.
Active Parking Assist is an electronic parking aid with ultrasound. Ultrasound is used to measure the road on both sides of the vehicle.
A suitable parking space is indicated by the parking symbol. Active steering intervention can assist you during parking. You may also use PARKTRONIC ( Y page 183). When
PARKTRONIC is switched off, Active Parking
Assist is also unavailable.
Use Active Parking Assist for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement
Parking tips:
R on narrow roads, drive past the parking space as close as possible.
R parking spaces that are littered, overgrown or partially occupied by trailer drawbars might be identified incorrectly or not at all.
R snowfall or heavy rain may lead to a parking space being measured inaccurately.
R pay attention to the PARKTRONIC
( Y page 185) warning messages during the parking procedure.
R you can intervene in the steering procedure to correct it at any time. Active Parking
Assist will then be canceled.
R when transporting a load which protrudes from your vehicle, you should not use
Active Parking Assist.
R when snow chains or an emergency spare wheel are mounted, you should not use
Active Parking Assist here either.
R make sure that the tire pressures are always correct. This has a direct influence on the parking characteristics of the vehicle.
R the way your vehicle is positioned in the parking space after parking is dependent on various factors. These include the position and shape of the vehicles parked in front and behind it and the conditions of the location. It may be the case that Active
Parking Assist guides you too far into a parking space, or not far enough into it. In some cases, it may also lead you across or onto the curb. If necessary, you should abort the parking procedure with Active
Parking Assist.
R you can also engage forward gear prematurely. The vehicle redirects and does not drive as far into the parking space.
Should the gear change occur too soon to achieve a sensible parking position, the parking procedure will be aborted.

;
Parking symbol
= Detected parking space on the right
Active Parking Assist is switched on automatically when driving forwards. The system is operational at speeds of up to approximately 22 mph (35 km/h). While in operation, the system independently locates and measures parking spaces on both sides of the vehicle. When driving at speeds below
19 mph (30 km/h), you will see the parking symbol as a status indicator in the instrument cluster. By default, Active Parking Assist only displays parking spaces on the frontpassenger side. Parking spaces on the driver's side are displayed as soon as the turn signal on the driver's side is activated. To park on the driver's side, you must leave the driver's side turn signal switched on. This must remain switched on until you acknowledge the use of Active Parking Assist by pressing the a button on the multifunction steering wheel.
When a parking space has been detected, an arrow towards the right or the left also appears.
Active Parking Assist will only detect parking spaces:
R that are parallel to the direction of travel
R that are at least 59 in (1.5 m) wide
R that are at least 51 in (1.3 m) longer than your vehicle
A parking space is displayed while you are driving past it, and until you are approximately 50 ft (15 m) away from it.

Driving systems
General notes
Blind Spot Assist uses a radar sensor system to monitor the areas on both sides of your vehicle. It supports you from speeds of approximately 20 mph (30 km/h). A warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lane, you will also receive an optical and audible collision warning. Blind Spot Assist uses sensors in the rear bumper for monitoring purposes.
For Blind Spot Assist to assist you when driving, the radar sensor system must be activated ( Y page 223) and operational.
Monitoring range of the sensors
G WARNING
Blind Spot Assist monitors certain areas in the immediate vicinity of your vehicle. Vehicles that approach and drive past at high speeds are not detected. There is no display and no warning.
If the lanes are very wide, it may not be possible to monitor the complete width of the neighboring lane. For this reason, vehicles in the next lane may not be detected, especially if they are driving in a staggered formation.
This may be the case if vehicles are driving at that edge of their lane which is furthest away from your vehicle.
Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.
The Blind Spot Assist monitors the area up to
3.0 m behind your vehicle and directly next to your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the lane beyond the lane next to your vehicle may be indicated, especially if the vehicles are not driving in the middle of their lane. This may be the case if there are vehicles driving at the inner edge of their lanes.
Due to the nature of the system:
R warnings may be issued in error when driving close to crash barriers or similar solid lane borders.
R warnings may be interrupted when driving alongside long vehicles, for example lorries, for a prolonged time.
The two radar sensors for Blind Spot Assist are integrated into the sides of the rear bumper. Make sure that the bumper is free from dirt, ice or slush around the sensors. The sensors must not be covered, for example by cycle racks or overhanging loads. Following a severe impact or in the event of damage to the bumpers, have the function of the sensors checked at a qualified specialist workshop.
Blind Spot Assist may otherwise not work properly.

General notes
Active Blind Spot Assist uses a radar sensor system to monitor the side areas of your vehicle which are in back of the driver. A warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lane, you will also receive an optical and audible warning. If a risk of lateral collision is detected, corrective braking may help you
Z
200
Driving systems avoid a collision. To support the coursecorrecting brake application, Active Blind
Spot Assist uses the forward-facing radar sensor system. The free space in the direction of travel is then evaluated.
Active Blind Spot Assist supports you from a speed of approximately 20 mph (30 km/h).
For Active Blind Spot Assist to assist you when driving, the radar sensor system must be activated ( Y page 223) and operational.
Monitoring area
G WARNING
Active Blind Spot Assist monitors certain areas in the immediate vicinity of your vehicle.
Vehicles that approach and drive past at high speeds are not detected. No visual nor audible warnings are emitted and the system does not brake the vehicle to correct your course.
If the lanes are very wide, it may not be possible to monitor the complete width of the neighboring lane. For this reason, vehicles in the next lane may not be detected, especially if they are driving in a staggered formation.
This may be the case if vehicles are driving at that edge of their lane which is furthest away from your vehicle.
Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.
Active Blind Spot Assist monitors the area up to 10 ft (3.0m) behind your vehicle and directly next to your vehicle, as shown in the diagram. For this purpose, Active Blind Spot
Assist uses radar sensors in the rear bumper.
If the lanes are narrow, vehicles driving in the lane beyond the lane next to your vehicle may be indicated, especially if the vehicles are not driving in the middle of their lane. This may be the case if there are vehicles at the inner edge of your lane.
Due to the nature of the system:
R warnings may be issued in error when driving close to crash barriers or similar solid lane borders.
R warnings may be interrupted when driving alongside long vehicles, for example lorries, for a prolonged time.
The Active Blind Spot Assist radar sensors are integrated into the front and rear bumpers and behind a cover in the radiator grill. Make sure that the bumpers and the cover in the radiator grill are free of dirt, ice or slush. The rear sensors must not be covered, for example by cycle racks or overhanging cargo.
Following a severe impact or in the event of damage to the bumpers, have the function of the radar sensors checked at a qualified specialist workshop. Active Blind Spot Assist may otherwise no longer work properly.

Indicator and warning display
G WARNING
Active Blind Spot Assist is not active at speeds below 20 mph (30km/h). The indicator lamps in the exterior mirrors are yellow. Vehicles in the monitoring range are then not indicated.
Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.
: Yellow indicator lamp/red warning lamp
When Active Blind Spot Assist is activated, indicator lamp : in the exterior mirrors lights up yellow at speeds of up to
20 mph(30km/h). At speeds above 20 mph
(30km/h), the indicator lamp goes out and
Active Blind Spot Assist is operational.
If a vehicle is detected within the monitoring range of Blind Spot Assist at speeds above
20 mph (30km/h), warning lamp : on the corresponding side lights up red. This warning is always given when a vehicle enters the blind spot monitoring range from behind or from the side. When you overtake a vehicle, the warning only occurs if the difference in speed is less than 7 mph (12km/h).
The yellow indicator lamp goes out if reverse gear is engaged. In this event, Active Blind
Spot Assist is no longer active.
The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light.
Visual and audible collision warnings
If you switch on the turn signals to change lanes and a vehicle is detected in the side monitoring range, you receive a visual and acoustic collision warning. You then hear a double warning tone and red warning lamp : flashes. If the turn signal remains on, detected vehicles are indicated by the flashing of red warning lamp :. There are no further warning tones.
Course-correcting brake application
G WARNING
Active Blind Spot Assist is only an aid designed to assist driving. It is not a substitute for attentive driving. In some cases, the course-correcting brake application is not sufficient to avoid a collision. In such a case, you must steer, brake or accelerate.
In very rare cases, the system may erroneously detect a danger of collision in the area of crash barriers or similar lane borders and apply the brakes. Active Blind Spot Assist does not detect all traffic situations and road users. Always make sure that there is sufficient distance on the side for other traffic or obstacles. An inappropriate brake application may be interrupted at any time if you steer slightly in the opposite direction or accelerate.
You are responsible for driving at appropriate speeds, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

Active Lane Keeping Assist
Important safety notes
G WARNING
Active Lane Keeping Assist does not keep your vehicle in its lane. It is only an aid and may detect the lane markings on the road incorrectly or not at all.
The system may be impaired or may not function if:
R there is poor visibility, e.g. due to inadequate illumination of the road surface, snow, rain, fog or spray.
R there is glare, e.g. from oncoming traffic, the sun, or reflection from other vehicles.
R the windshield is dirty, fogged up or covered, for instance by a sticker, in the vicinity of the camera.
R several or no lane markings for a single lane are present.
R the lane markings are worn away, dark or covered up, e.g. by dirt or snow.
R the distance to the vehicle in front is too small, and as a result the lane markings cannot be recognized.
R the lane markings on the road are unclear, e.g. near roadworks.
Driving systems
203
R the lane markings change quickly, e.g.
branch off, cross or merge.
R the road is narrow and winding.
Active Lane Keeping Assist cannot detect road and traffic conditions. It is not a substitute for attentive driving. You are responsible for the vehicle's speed, braking in good time and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.
General notes
Active Lane Keeping Assist monitors the area in front of your vehicle by means of a camera : at the top of the windshield. Active
Lane Keeping Assist detects lane markings on the road and warns you before you leave your lane unintentionally. If you do not react to the warning, a lane-correcting application of the brakes can bring the vehicle back into the original lane.
If you have selected km as the display unit in the Display Unit Speed-/
Odometer ( Y page 220) function in the onboard computer, Active Lane Keeping Assist assists you at speeds above 60 km/h. If miles is selected as the display unit, the assistance range starts at 40 mph.
Warning vibration in the steering wheel
A warning may be given if a front wheel passes over a lane marking. It will warn you by means of intermittent vibration in the steering wheel for up to 1.5 seconds.
In order that you are warned only when necessary and in good time if you cross the lane marking, the system recognizes certain conditions and warns you accordingly.
The warning vibration occurs earlier if:
R you approach the outer lane marking on a bend.
R the road has very wide lanes, e.g. a freeway.
R the system recognizes solid lane markings.
The warning vibration occurs later if:
R the road has narrow lanes.
R you cut the corner on a bend.

The message shown in the illustration appears in the multifunction display when a lane-correcting brake application occurs.
If you leave your lane under certain circumstances the vehicle will brake briefly on one side. This is meant to assist you in bringing the vehicle back to the original lane.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
A lane-correcting brake application can only be made after driving over a solid, recognizable lane marking. Before this, a warning must be given by means of intermittent vibration in the steering wheel.
In addition, a lane with lane markings on both sides must be recognized. The brake application also slightly reduces vehicle speed.
i A further lane-correcting brake application can only occur after your vehicle has returned to the original lane.
No lane-correcting brake application occurs if:
R you clearly and actively steer, brake or accelerate.
R you cut the corner on a sharp bend.
R you have switched on the turn signals.
R a driving safety system intervenes, e.g.
