PRE-SAFE®takes the following measuresdepending on the hazardous situation detected:
Rthe front seat belts are pre-tensioned.
Rif the vehicle skids, the side windows and thesliding sunroof are closed.
Rvehicles with the memory function for thefront-passenger seat: the front-passengerseat is adjusted if it is in an unfavorable posi-tion.
If the hazardous situation passes without result-
ing in an accident, PRE-SAFE®slackens the belt
pre-tensioning. All settings made by PRE-SAFE®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
XMove the seat backrest or seat back slightlywhen the vehicle is stationary.The seat belt pre-tensioning is reduced andthe locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE®convenience function. Informa-tion about the convenience function can befound under "Belt adjustment" (Ypage 47).
PRE-SAFE®PLUS (anticipatory occu-
pant protection system PLUS)
Introduction
PRE-SAFE®PLUS is only available in vehicleswith the Driving Assistance package.
Using the radar sensor system, PRE-SAFE®
PLUS is able to detect that a frontal or rear-endcollision is imminent. In certain hazardous sit-
uations, PRE-SAFE®PLUS takes pre-emptivemeasures to protect the vehicle occupants.
Important safety notes
The intervention of PRE-SAFE®PLUS cannotprevent an imminent collision.
The driver is not warned about the intervention
of PRE-SAFE®PLUS.
PRE-SAFE®PLUS does not intervene:
Rif the vehicle is backing up
Rwhen the vehicle is towing a trailer and thereis a risk of a rear-end collision
When driving, or when parking or exiting a park-ing space using Active Parking Assist, PRE-
SAFE®PLUS will not apply the brakes.
Function
PRE-SAFE®PLUS intervenes in certain situa-tions if the radar sensor system detects animminent frontal or rear-end collision.
PRE-SAFE®PLUS takes the following measuresdepending on the hazardous situation detected:
Rif the radar sensor system detects that ahead-on collision is imminent, the seat beltsare pre-tensioned.
Rif the radar sensor system detects that a rear-end collision is imminent:
-the brake pressure is increased if the driverapplies the brakes when the vehicle is sta-tionary.
-the seat belts are pre-tensioned.
The PRE-SAFE®PLUS braking application is can-celed:
Rif the accelerator pedal is depressed when agear is engaged
Rif the risk of a collision passes or is no longerdetected
Rif Active Distance Assist DISTRONIC indicatesan intention to intervene
If the hazardous situation passes without result-ing in an accident, the original settings arerestored.
Automatic measures after an acci-
dent
Immediately after an accident, the followingmeasures are implemented, depending on thetype and severity of the impact:
Rthe hazard warning lamps are switched on
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rvehicles with a memory function: the electri-cally adjustable steering wheel is raised whenthe driver's door is opened
Rthe engine is switched off and the fuel supplyis cut off
Rvehicles with mbrace: automatic emergencycall

Children in the vehicle
Important safety notes
Accident statistics show that children securedin the rear seats are safer than children securedin the front-passenger seat. For this reason,Mercedes-Benz strongly advises that you installa child restraint system on a rear seat. Childrenare generally better protected there.
If a child younger than twelve years old andunder 5 ft (1.50 m) in height is traveling in thevehicle:
Ralways secure the child in a child restraintsystem suitable for Mercedes-Benz vehicles.The child restraint system must be appropri-ate to the age, weight and size of the child.
Rbe sure to observe the instructions and safetynotes in this section in addition to the childrestraint system manufacturer's installationinstructions.
Ralways observe the instructions and safetynotes on the "Occupant classification system(OCS)". (Ypage 51)
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking positionP.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
If persons, particularly children are subjected
to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Pro-
tect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in
the vehicle.
Always ensure that all vehicle occupants havetheir seat belts fastened correctly and are sittingproperly. Particular attention must be paid tochildren.
Observe the safety notes on the seat belt(Ypage 45)and the notes on correct use of seatbelts (Ypage 46).
A booster seat may be necessary to achieveproper seat belt positioning for children over40 lbs(18 kg) until they reach a height where athree-point seat belt can be properly fastenedwithout a booster seat.
Special seatbelt retractor
GWARNING
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt retrac-
tor is disabled and the inertia real draws in a
portion of the seat belt. The seat belt cannot
be immediately refastened. There is an
increased risk of injury, possibly even fatal.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions. Reactivate
the special seat belt retractor and secure the
child restraint system properly.
All seat belts in the vehicle, except the driver'sseat belt, are equipped with a special seat beltretractor. When activated, the special seat beltretractor ensures that the seat belt cannotslacken once the child seat is secured.

Overview of driving safety systems
In this section, you will find information aboutthe following driving safety systems:
RABS (Anti-lockBrakingSystem)(Ypage 65)
RBAS (BrakeAssistSystem) (Ypage 66)
RActive Brake Assist (Ypage 66)
RESP®(ElectronicStabilityProgram)(Ypage 68)
REBD (ElectronicBrake forceDistribution)(Ypage 72)
RADAPTIVE BRAKE (Ypage 72)
RActive Brake Assist with cross-traffic function(Ypage 72)
RSTEER CONTROL (Ypage 75)
Important safety notes
If you fail to adapt your driving style or if you areinattentive, the driving safety systems can nei-ther reduce the risk of an accident nor overridethe laws of physics. Driving safety systems aremerely aids designed to assist driving. You areresponsible for maintaining the distance to thevehicle in front, for vehicle speed, for braking ingood time, and for staying in lane. Always adaptyour driving style to suit the prevailing road andweather conditions and maintain a safe distancefrom the vehicle in front. Drive carefully.
The driving safety systems described only workas effectively as possible when there is ade-quate contact between the tires and the roadsurface. Pay particular attention to the informa-tion regarding tires, recommended minimumtire tread depths etc. in the "Wheels and tires"section (Ypage 330).
In wintry driving conditions, always use wintertires (M+S tires)and if necessary, snow chains.Only in this way will the driving safety systemsdescribed in this section work as effectively aspossible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such a way thatthe wheels do not lock when you brake. Thisallows you to continue steering the vehicle whenbraking.
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 conditions.ABS works on slippery surfaces, even when youonly brake gently.
Important safety notes
iObserve the "Important safety notes" sec-tion (Ypage 65).
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid-
ding 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 259) and dis-play messages which may be shown in theinstrument cluster (Ypage 228).
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 as areminder to take extra care while driving.

KEYLESS-GO
General notes
Bear in mind that the engine can be started byany of the vehicle occupants if there is a Smart-Key in the vehicle (Ypage 133).
Locking/unlocking centrally
You can start, lock or unlock the vehicle usingKEYLESS-GO. To do this, you only need carry theSmartKey with you. You can combine the func-tions of KEYLESS-GO with those of a conven-tional SmartKey. Unlock the vehicle by usingKEYLESS-GO, for instance, and lock it using the 7button on the SmartKey.
The driver's door and the door at which the han-dle is used, must both be closed. The SmartKeymust be outside the vehicle. When locking orunlocking with KEYLESS-GO, the distancebetween the SmartKey and the correspondingdoor handle must not be greater than 3 ft (1 m).
A brief radio connection between the vehicleand the SmartKey determines whether a validSmartKey is in, or in the direct vicinity of, thevehicle. This occurs, for example:
Rwhen starting the engine
Rwhile driving
Rwhen using HANDS-FREE ACCESS
Rwhen the external door handles are touched
Rduring convenience closing
XTo unlock the vehicle:touch the inner sur-face of the door handle.
XTo lock the vehicle:touch sensor surface Cor D.
