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

Safety

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.

You can thus avoid the risks that could arise asa result of:
Ran incorrectly categorized person in the front-passenger seat
Rdeactivating the front passenger front air bagunintentionally
Rthe unsuitable positioning of the childrestraint system, e.g. too close to the dash-board
Rearward-facing child restraint system
If circumstances require you to secure a child ina rearward-facing child restraint system on thefront-passenger seat, always make sure that thefront passenger front air bag is deactivated.Only if the PASSENGER AIR BAG OFF indicatorlamp is lit continuously (Ypage 44), is the frontpassenger front air bag deactivated.
Always observe the child restraint system man-ufacturer's installation and operating instruc-tions.
Forward-facing child restraint system
If it is absolutely necessary to install a forward-facing child restraint system on the front-passenger seat, always move the front-passenger seat as far back as possible. Fullyretract the seat cushion length. The entire baseof the child restraint system must always rest onthe seat cushion of the front-passenger seat.The backrest of the child restraint system mustlie as flat as possible against the backrest of thefront-passenger seat. The child restraint systemmust not touch the roof or be subjected to a loadby the head restraint. Adjust the angle of theseat backrest and the head restraint positionaccordingly. Always make sure that the shoul-der belt strap is correctly routed from the vehi-cle belt outlet to the shoulder belt guide on thechild restraint system. The shoulder belt strapmust be routed forward and down from the vehi-cle belt outlet. If necessary, adjust the vehiclebelt outlet and the front-passenger seat accord-ingly.
Always observe the child restraint system man-ufacturer's installation and operating instruc-tions.

BAS (Brake Assist System)
General information
BAS operates in emergency braking situations.If you depress the brake pedal quickly, BASautomatically boosts the braking force, thusshortening the stopping distance.
Important safety notes
iObserve the "Important safety notes" sec-tion (Ypage 65).
GWARNING
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.
Braking
XKeep the brake pedal firmly depressed untilthe emergency braking situation is over.ABS prevents the wheels from locking.
The brakes will function as usual once yourelease the brake pedal. BAS is deactivated.
Active Brake Assist
General information
iObserve the "Important safety notes" sec-tion (Ypage 65).
Active Brake Assist consists of a distance warn-ing function with an autonomous braking func-tion and Adaptive Brake Assist.
Active Brake Assist can help you to minimize therisk of a collision with the vehicle traveling infront or reduce the effects of such a collision.
If Active Brake Assist detects that there is a riskof collision, you will be warned visually andacoustically. If you do not react to the visual andaudible collision warning, autonomous brakingcan be initiated in critical situations. If you applythe brake yourself in a critical situation, Adap-tive Brake Assist of the Active Brake Assist sys-tem supports you.
Important safety notes
In particular, the detection of obstacles can beimpaired if:
RThere is dirt on the sensors or anything elsecovering the sensors
RThere is snow or heavy rain
RThere is interference by other radar sources
RThere are strong radar reflections, for exam-ple in parking garages
