Driving safety systems
Overview of driving safety systems
In this section, you will find information aboutthe following driving safety systems:
RABS (Anti-lockBrakingSystem)(Ypage 60)
RBAS (BrakeAssistSystem) (Ypage 61)
RActive Brake Assist (Ypage 61)
RESP®(ElectronicStabilityProgram)(Ypage 63)
REBD (ElectronicBrake forceDistribution)(Ypage 67)
RADAPTIVE BRAKE (Ypage 67)
RSTEER CONTROL (Ypage 67)
Important safety notes
If you fail to adapt your driving style or if youare inattentive, the driving safety systems canneither reduce the risk of an accident noroverride the laws of physics. Driving safetysystems are merely aids designed to assistdriving.
You are responsible for maintaining the dis-tance to the vehicle in front, for vehicle speed,for braking in good time, and for staying inlane. Always adapt your driving style to suitthe prevailing road and weather conditions andmaintain a safe distance from the vehicle infront. Drive carefully.
The driving safety systems described onlywork as effectively as possible when there isadequate contact between the tires and theroad surface. Please pay special attention tothe notes on tires, recommended minimumtire tread depths, etc. (Ypage 305).
In wintry driving conditions, always use wintertires (M+S tires) and if necessary, snowchains. Only in this way will the driving safetysystems described in this section work aseffectively as possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such a waythat the wheels do not lock when you brake.
This allows you to continue steering the vehi-cle when braking.
The%ABS warning lamp in the instrumentcluster lights up when the ignition is switchedon. It goes out when the engine is running.
ABS works from a speed of about 5 mph(8 km/h), regardless of road-surface condi-tions. ABS works on slippery surfaces, evenwhen you only brake gently.
Important safety notes
iObserve the "Important safety notes" sec-tion (Ypage 60).
GWARNING
If ABS is malfunctioning, the wheels could
lock when braking. The steerability and
braking characteristics would be severely
affected. There is an increased danger of
skidding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,including driving safety systems, will alsobecome inoperative. Observe the informationon the ABS warning lamp (Ypage 233) anddisplay messages which may be shown in theinstrument cluster (Ypage 204).
Braking
XIf ABS intervenes:continue to depress thebrake pedal vigorously until the braking sit-uation is over.
XTo make a full brake application:depressthe brake pedal with full force.
If ABS intervenes when braking, you will feel apulsing in the brake pedal.
The pulsating brake pedal can be an indicationof hazardous road conditions, and functions asa reminder to take extra care while driving.
Off-road ABS
An ABS system specifically suited to off-roadterrain is activated automatically once the off-road program is activated (Ypage 170).
At speeds below 20 mph (30 km/h), the frontwheels lock cyclically during braking. The dig-ging-in effect achieved in the process reduces

Saf ety

Only deactivate ESP®in the situations
described in the following.
The spinning of the wheels results in a cuttingaction for better traction on loose surfaces.
It may be best to deactivate ESP®in the fol-lowing situations:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
iActivate ESP®as soon as the situations
described above no longer apply. ESP®willotherwise not be able to stabilize the vehicleif the vehicle starts to skid or a wheel startsto spin.
!Avoid spinning the driven wheels for an
extended period with ESP®deactivated. Youcould otherwise damage the drivetrain.
Deactivating/activating ESP®
You can deactivate or activate ESP®via theon-board computer (Ypage 197).
ESP®deactivated:
The

For this reason, in the event of heavy rain or inconditions in which hydroplaning may occur,you must drive in the following manner:
Rlower your speed
Ravoid ruts
Ravoid sudden steering movements
Rbrake carefully
Driving on flooded roads
!Bear in mind that vehicles traveling in frontor in the opposite direction create waves.This may cause the maximum permissiblewater depth to be exceeded.
Failure to observe these notes may result indamage to the engine, electrical systemsand transmission.
If you have to drive on stretches of road onwhich water has collected, please bear in mindthat:
Rin the case of standing water, the waterlevel may be no higher than the lower edgeof the vehicle body
Ryou should drive no faster than walking pace
Winter driving
GWARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's brak-
ing effect, the drive wheels could lose their
grip. There is an increased danger of skid-
ding and accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter
the vehicle. This is the case, e.g. if the vehi-
cle becomes trapped in snow. There is a risk
of fatal injury.
If you leave the engine or the auxiliary heat-
ing running, make sure the exhaust pipe and
area around the vehicle are clear of snow.
To ensure an adequate supply of fresh air,
open a window on the side of the vehicle
that is not facing into the wind.
Have your vehicle winter-proofed at a qualifiedspecialist workshop at the onset of winter.
Drive particularly carefully on slippery roadsurfaces. Avoid sudden acceleration, steeringand braking maneuvers. Do not use cruisecontrol or Active Distance Assist DISTRONIC.
If the vehicle threatens to skid or cannot bestopped when moving at low speed:
XShift the transmission to position\\.
XTry to bring the vehicle under control usingcorrective steering.
The outside temperature indicator is notdesigned to serve as an ice-warning deviceand is therefore unsuitable for that purpose.Changes in the outside temperature are dis-played after a short delay.
Indicated temperatures just above the freezingpoint do not guarantee that the road surface isfree of ice. The road may still be icy, especiallyin wooded areas or on bridges.
You should pay special attention to road con-ditions when temperatures are around freezingpoint.
For more information on driving with snowchains, see (Ypage 307).
For more information on driving with summertires, see (Ypage 306).
Observe the notes in the "Winter operation"section (Ypage 306).
Off-road driving
Important safety notes
GWARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is
a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle.

iIf RACE START is used repeatedly within ashort period of time, it is only availableagain after the vehicle has been driven acertain distance.
AMG adaptive sport suspension sys-
tem
General notes
The electronically controlled damping systemworks continuously. This improves drivingsafety and ride comfort.
The damping is tuned individually to eachwheel and depends on:
Ryour driving style, e.g. sporty
Rthe road surface condition, e.g. bumps
Ryour individual selection ofSportorCom-fort
The suspension setting is adjusted using thecorresponding button in the center console.
iThe mode can also be set using the AMGDYNAMIC SELECT controller (Ypage 133).
Each time you start the engine with the Smart-Key or the Start/Stop button,Comfortmodeis activated. For further information aboutstarting the engine, see (Ypage 125).
Sport mode
The firmer setting of the suspension tuning inSportmode ensures even better contact withthe road. Select this mode when employing asporty driving style, e.g. on winding countryroads.

4MATIC
!Never tow the vehicle with one axle raised.This may damage the differential. Damageof this sort is not covered by the Mercedes-Benz Limited Warranty. All wheels mustremain either on the ground or be fullyraised. Observe the instructions for towingthe vehicle with all wheels in full contactwith the ground.
4MATIC, together with ESP®, improves thetraction of your vehicle whenever a drivewheel spins due to insufficient grip.
If you fail to adapt your driving style, 4MATICcan neither reduce the risk of accident noroverride the laws of physics. 4MATIC cannottake account of road, weather and traffic con-ditions. 4MATIC is only an aid. You are respon-sible for the distance to the vehicle in front, forvehicle speed, for braking in good time and forstaying in your lane.
If a drive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far asnecessary when pulling away.
RAccelerate less when driving.
iIn wintry driving conditions, the maximumeffect of 4MATIC can only be achieved if youuse winter tires (M+S tires), with snowchains if necessary.
