Important safety notes If you fail to adapt your driving style or become distracted, the driving safety systems can neither reduce the risk of accident nor override the laws of physics. Driving safety systems are merely aids designed to assist driving. You are responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time. Always adapt your driving style to suit the prevailing road, weather and traffic conditions and maintain a safe distance from the vehicle in front. Drive carefully. i The driving safety systems described only work as effectively as possible when there is adequate contact between the tires and the road surface. Pay particular attention to the information regarding tires, recommended minimum tire tread depths etc. in the "Wheels and tires" section (Y page 298). In wintry driving conditions, always use winter tires (M+S tires) and if necessary, snow chains. Only in this way will the driving safety systems described in this section work as effectively as possible.
ABS (Anti-lock Braking System) Important safety notes i Observe the "Important safety notes"
section for driving safety systems (Y page 59). G WARNING If ABS is faulty, the wheels could lock when braking. The steerability and braking characteristics may be severely impaired. Additionally, further driving safety systems
Driving safety systems
59
are deactivated. There is an increased danger of skidding and accidents. Drive on carefully. Have ABS checked immediately at a qualified specialist workshop.
When ABS is malfunctioning, other systems, including driving safety systems, will also become inoperative. Observe the information on the ABS warning lamp (Y page 225) and display messages which may be shown in the instrument cluster (Y page 201). ABS regulates brake pressure in such a way that the wheels do not lock when you brake. This allows you to continue steering the vehicle when braking. ABS works from a speed of about 5 mph (8 km/h) upwards, regardless of road-surface conditions. ABS works on slippery roads, even if you only brake gently. The ! ABS warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out when the engine is running.
Braking X If ABS intervenes: continue to depress the
brake pedal vigorously until the braking situation is over.
X To make a full brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel a pulsing in the brake pedal. The pulsating brake pedal can be an indication of hazardous road conditions, and functions as a reminder to take extra care while driving.
BAS (Brake Assist System) i Observe the "Important safety notes"
section (Y page 59).
60 Driving safety systems
G WARNING If BAS is malfunctioning, the braking distance in an emergency braking situation is increased. There is a risk of an accident. In an emergency braking situation, depress the brake pedal with full force. ABS prevents the wheels from locking.
BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance. The brakes will function as usual once you release the brake pedal. BAS is deactivated.
COLLISION PREVENTION ASSIST General notes COLLISION PREVENTION ASSIST consists of the Adaptive Brake Assist and the distance warning function, which are described in the following.
Distance warning function Important safety notes i Observe the "Important safety notes"
section for driving safety systems (Y page 59). G WARNING The distance warning function does not react: Rto people or animals Rto oncoming vehicles Rto crossing traffic Rwhen cornering Thus, the distance warning function cannot provide a warning in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake.
The distance warning function cannot always clearly identify objects and complex traffic situations.
In such cases, the distance warning function may: Rgive an unnecessary warning Rnot give a warning Always pay careful attention to the traffic situation and do not rely solely on the distance warning function. Function X To activate/deactivate: activate or
deactivate the distance warning function in the on-board computer (Y page 195).
If the distance warning function is activated, the Ä symbol appears in the multifunction display unless the HOLD function is active (Y page 168). On vehicles with Active Parking Assist, the Ä symbol is displayed when P is engaged or you are driving faster than 22 mph (35 km/h). The distance warning function can help you to minimize the risk of a front-end collision with a vehicle ahead or reduce the effects of such a collision. If the distance warning function detects that there is a risk of a collision, you will be warned visually and acoustically. The distance warning function cannot prevent a collision without your intervention. Starting at a speed of around 20 mph (30 km/h), this function warns you if you rapidly approach a vehicle in front. An intermittent warning tone will then sound and the · distance warning lamp will light up in the instrument cluster. X Brake immediately in order to increase the
distance from the vehicle in front.
or X Take evasive action provided it is safe to do
so.
For the distance warning function to assist you when driving, the function must be activated in the on-board computer and be operational (Y page 195).
Driving safety systems
61
Due to the nature of the system, particularly complicated driving conditions may cause the system to display unnecessary warnings. With the help of the radar sensor system, the distance warning function can detect obstacles that are in the path of your vehicle for an extended period of time. At speeds up to 40 mph (70 km/h), the distance warning function may also detect stationary obstacles, for example stopped or parked vehicles. If you approach an obstacle and the distance warning function detects a risk of a collision, the system will initially alert you both visually and acoustically. In particular, the detection of obstacles can be impaired if: Rdirt on the sensors or anything else
covering the sensors
Rsnow or heavy rain Rinterference by other radar sources Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the vehicle, have the configuration and operation of the radar sensor checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible damage to the front of the vehicle.
Adaptive Brake Assist i Observe the "Important safety notes"
section for driving safety systems (Y page 59). G WARNING Adaptive Brake Assist cannot always clearly identify objects and complex traffic situations. In these cases, Adaptive Brake Assist may not intervene. There is a risk of an accident.
Always pay careful attention to the traffic situation and be ready to brake. G WARNING Adaptive Brake Assist does not react: Rto people or animals Rto oncoming vehicles Rto crossing traffic Rto stationary obstacles Rwhen cornering As a result, Adaptive Brake Assist may not intervene in all critical conditions. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake.
Adaptive Brake Assist provides braking assistance in hazardous situations at speeds greater than 20 mph (30 km/h) and uses radar sensor technology to assess the traffic situation. With the help of a sensor system, adaptive Brake Assist can detect obstacles that are in the path of your vehicle for an extended period of time. Should you approach an obstacle and Adaptive Brake Assist has detected a risk of collision, Adaptive Brake Assist calculates the braking force necessary to avoid a rear-end collision. Should you apply the brakes vigorously, Adaptive Brake Assist will automatically increase the braking force to a level suitable for the traffic conditions. X Keep the brake pedal depressed until the
emergency braking situation is over. ABS prevents the wheels from locking.
The brakes will work normally again if: Ryou release the brake pedal. Rthere is no longer any danger of a rear-end
collision.
Rno obstacle is detected in front of your
vehicle.
Adaptive Brake Assist is then deactivated.
62 Driving safety systems
Up to vehicle speeds of around 155 mph (250 km/h), adaptive Brake Assist is capable of reacting to moving objects that have already been recognized as such at least once over the period of observation. Adaptive Brake Assist does not react to stationary obstacles. If Adaptive Brake Assist is not available due to a malfunction in the radar sensor system, the brake system remains available with full brake boosting effect and BAS. In particular, the detection of obstacles can be impaired if there is: Rdirt on the sensors or anything else
covering the sensors
Rsnow or heavy rain Rinterference by other radar sources Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the vehicle, have the configuration and operation of the radar sensor checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible damage to the front of the vehicle.
Adaptive brake lights If you brake sharply from a speed of more than 50 km/h or if braking is assisted by BAS or Adaptive Brake Assist, the brake lamps flash rapidly. In this way, traffic traveling behind you is warned in an even more noticeable manner. If you brake sharply to a standstill from a speed of more than 70 km/h, the hazard warning lamps are activated automatically. If the brakes are applied again, the brake lamps light up continuously. The hazard warning lamps switch off automatically if you travel faster than 10 km/h. You can also switch off
the hazard warning lamps using the hazard warning button (Y page 101). i Adaptive brake lamps are only available in
certain countries.
ESP® (Electronic Stability Program) General notes i Observe the "Important safety notes"
section (Y page 59).
ESP® monitors driving stability and traction, i.e. power transmission between the tires and the road surface. If ESP® detects that the vehicle is deviating from the direction desired by the driver, one or more wheels are braked to stabilize the vehicle. The engine output is also modified to keep the vehicle on the desired course within physical limits. ESP® assists the driver when pulling away on wet or slippery roads. ESP® can also stabilize the vehicle during braking.
ETS (Electronic Traction System) i Observe the "Important safety notes"
section for driving safety systems (Y page 59).
ETS traction control is part of ESP®. ETS brakes the drive wheels individually if they spin. This enables you to pull away and accelerate on slippery surfaces, for example if the road surface is slippery on one side. ETS remains active when you deactivate ESP®.
Important safety notes G WARNING If ESP® is malfunctioning, ESP® is unable to stabilize the vehicle. Additionally, further driving safety systems are deactivated. This increases the risk of skidding and an accident. Drive on carefully. Have ESP® checked at a qualified specialist workshop.
! When testing the electric parking brake on a braking dynamometer, switch off the ignition. Application of the brakes by ESP® may otherwise destroy the brake system.
When towing your vehicle with the front axle raised, observe the notes on ESP®(Y page 293). ESP® is deactivated if the å ESP® OFF warning lamp in the instrument cluster lights up continuously when the engine is running. If the ÷ ESP® warning lamp and the å ESP® OFF warning lamp are lit continuously, ESP® is not available due to a malfunction. Observe the information on warning lamps (Y page 227) and display messages which may be shown in the instrument cluster (Y page 201). i Only use wheels with the recommended
tire sizes. Only then will ESP® function properly.
Characteristics of ESP® General information ESP® is activated automatically when the engine is started. If ESP® intervenes, the ÷ ESP® warning lamp flashes in the instrument cluster. If ESP® intervenes: X Do not deactivate ESP® under any
circumstances.
X Only depress the accelerator pedal as far
as necessary when pulling away.
X Adapt your driving style to suit the
prevailing road and weather conditions.

Deactivating/activating ESP® Important safety notes i Observe the "Important safety notes"
section for driving safety systems (Y page 59).
You can select between the following states of ESP®: RESP® is activated. RESP® is deactivated. G WARNING If you deactivate ESP®, ESP® no longer stabilizes the vehicle. There is an increased risk of skidding and an accident. Only deactivate ESP® in the situations described in the following.
It may be best to deactivate ESP® in the following situations: Rwhen using snow chains Rin deep snow Ron sand or gravel i Activate ESP® as soon as the situations described above no longer apply. ESP® will otherwise not be able to stabilize the vehicle if the vehicle starts to skid or a wheel starts to spin.
! Avoid spinning the driven wheels for an extended period with ESP® deactivated. You could otherwise damage the drivetrain.
Deactivating/activating ESP® You can deactivate or activate ESP® via the on-board computer. X To deactivate:(Y page 194).
The å ESP® OFF warning lamp in the instrument cluster lights up.
X To activate:(Y page 194).
The å ESP® OFF warning lamp in the instrument cluster goes out.

Theft deterrent locking system
Characteristics when ESP® is deactivated If ESP® is deactivated and one or more wheels start to spin, the ÷ ESP® warning lamp in the instrument cluster flashes. In such situations, ESP® will not stabilize the vehicle. If you deactivate ESP®: RESP® no longer improves driving stability. Rthe engine's torque is no longer limited and
the drive wheels are able to spin. The spinning of the wheels results in a cutting action, which provides better grip.
RETS is still active. RESP® still provides support when you
brake.
EBD (electronic brake force distribution) i Observe the "Important safety notes"
section for driving safety systems (Y page 59). G WARNING If EBD has malfunctioned, the rear wheels can still lock, e.g. under full braking. This increases the risk of skidding and an accident. You should therefore adapt your driving style to the different handling characteristics. Have the brake system checked at a qualified specialist workshop.
Observe information regarding indicator and warning lamps (Y page 225) as well as display messages (Y page 203). EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking.
ADAPTIVE BRAKE ADAPTIVE BRAKE enhances braking safety and offers increased braking comfort. In addition to the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 168) and hill start assist
(Y page 136). For further information, see Driving tips (Y page 154).
STEER CONTROL STEER CONTROL helps you by transmitting a noticeable steering force to the steering wheel in the direction required for vehicle stabilization. This steering assistance is provided in particular if: Rboth right wheels or both left wheels are on
a wet or slippery road surface when you brake
Rthe vehicle starts to skid If ESP® is malfunctioning, you will not receive steering support from STEER CONTROL. Power steering will, however, continue to function.
Theft deterrent locking system Immobilizer The immobilizer prevents your vehicle from being started without the correct SmartKey. X To activate: remove the SmartKey from
the ignition lock.
X To deactivate: switch on the ignition. When leaving the vehicle, always take the SmartKey with you and lock the vehicle. The engine can be started by anyone with a valid SmartKey that is left inside the vehicle. i The immobilizer is always deactivated
when you start the engine. In the event that the engine cannot be started when the starter battery is fully charged, the immobilizer may be faulty. Contact an authorized Mercedes-Benz Center or call 1-800-FOR-MERCedes (in the USA) or 1-800-387-0100 (in Canada).
