General notes
HEnvironmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affec-
ted by these factors:
Roperating conditions of your vehicle
Ryour personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
Ravoid short trips as these increase fuel
consumption.
Ralways make sure that the tire pressures
are correct.
Rdo not carry any unnecessary weight.
Rremove roof racks once you no longer
need them.
Ra regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
Ralways have service work carried out at a
qualified specialist workshop.
Personal driving style:
Rdo not depress the accelerator pedal
when starting the engine.
Rdo not warm up the engine when the vehi-
cle is stationary.
Rdrive carefully and maintain a safe dis-
tance from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each
gear only up to

Restraint system warning lamp
The functions of the restraint system arechecked after the ignition is switched on andat regular intervals while the engine is running.Therefore, malfunctions can be detected ingood time.
The urestraint system warning lamp onthe instrument cluster lights up when the igni-tion is switched on. It goes out no later than afew seconds after the vehicle is started. Thecomponents of the restraint system are inoperational readiness.
A malfunction has occurred if the urestraint system warning lamp:
Rdoes not light up after the ignition isswitched on
Rdoes not go out after a few seconds with theengine running
Rlights up again while the engine is running
GWARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This can affect
for example the Emergency Tensioning
Device or the air bag. This poses an
increased risk of injury or even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop
as soon as possible.
PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp Cand PASSENGER AIR BAG OFF indicator
lamp Dare part of the Occupant Classifica-tion System (OCS).
The indicator lamps display the status of thefront-passenger front air bag.
RPASSENGER AIR BAG ON lights up for 60seconds, subsequently both indicator lampsare off (PASSENGER AIR BAG ON and OFF):the front-passenger front air bag is able todeploy in the event of an accident.
RPASSENGER AIR BAG OFF lights up: thefront-passenger front air bag is deactivated.It will then not be deployed in the event ofan accident.
If the PASSENGER AIR BAG ON indicator lampis off, only the PASSENGER AIR BAG OFF indi-cator lamp shows the status of the front-passenger front air bag. The PASSENGER AIRBAG OFF indicator lamp may be lit continu-ously or be off.
Depending on the person in the front-passenger seat, the front-passenger front airbag must either be deactivated or enabled;see the following points. You must make sureof this both before and during a journey.
RChildren in a child restraint system:whether the front-passenger front air bag isenabled or deactivated depends on theinstalled child restraint system, and the ageand size of the child. Therefore, be sure toobserve the notes on the "Occupant Classifi-cation System (OCS)" (Ypage 48) and on"Children in the vehicle" (Ypage 57).There you will also find instructions on rear-ward and forward-facing child restraint sys-tems on the front-passenger seat.
RAll other persons:depending on the classi-fication of the person in the front-passengerseat, the front-passenger front air bag isenabled or deactivated (Ypage 48). Besure to observe the notes on "Seatbelts“ (Ypage 41) and "Air bags"(Ypage 45). There you can also find infor-mation on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means ofrestricting the movement of vehicle occupantsin the event of an accident or the vehicle roll-ing over. This reduces the risk of vehicle occu-

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 head-on or rear-end collision is imminent. In certain hazardous
situations, 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 if thevehicle is backing up.
When driving, or when parking or exiting aparking 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 head-on or rear-end collision.
PRE-SAFE®PLUS takes the following meas-ures depending on the hazardous situationdetected:
Rif the radar sensor system detects that ahead-on collision is imminent, the seat beltsare pre-tensioned.
Rif the radar sensor system detects that arear-end collision is imminent:
-the brake pressure is increased if thedriver applies the brakes when the vehicleis stationary.
-the seat belts are pre-tensioned.
The PRE-SAFE®PLUS braking application iscanceled:
Rif the accelerator pedal is depressed when agear is engaged
Rif the risk of a collision passes or is no lon-ger detected
Rif Active Distance Assist DISTRONIC indi-cates an intention to intervene
If the hazardous situation passes withoutresulting in an accident, the original settingsare restored.
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
Rthe electrically adjustable steering wheel israised when the driver's door is opened
Rthe engine is switched off and the fuel sup-ply is cut off

Children in the vehicle
Important safety notes
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 andsafety notes in this section in addition to thechild restraint system manufacturer's instal-lation instructions.
Ralways observe the instructions and safetynotes on the "Occupant classification sys-tem (OCS)". (Ypage 48)
GWARNING
If you leave children unsupervised in the
vehicle, 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 subjec-
ted 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.
Protect it with a blanket, for example. If the
child restraint system has been exposed to
direct sunlight, let it cool down before secur-
ing the child in it. Never leave children unat-
tended in the vehicle.
Always ensure that all vehicle occupants havetheir seat belts fastened correctly and are sit-ting properly. Particular attention must be paidto children.
Observe the safety notes on the seat belt(Ypage 42) and the notes on correct use ofseat belts (Ypage 43).
A booster seat may be necessary to achieveproper seat belt positioning for children over40 lbs(18 kg)until they reach a height wherea three-point seat belt can be properly fas-tened without 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
retractor 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. Reacti-
vate the special seat belt retractor and
secure the child restraint system properly.
The seat belt on the front-passenger's side isequipped with a special seat belt retractor.When activated, the special seat belt retractorensures that the seat belt cannot slacken oncethe child seat is secured.

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)
RBrake Assist with cross-traffic function(Ypage 61)
RActive Brake Assist (Ypage 63)
RAdaptive brake lights (Ypage 65)
RESP®(ElectronicStabilityProgram)(Ypage 65)
REBD (ElectronicBrake forceDistribution)(Ypage 69)
RADAPTIVE BRAKE (Ypage 70)
RActive Brake Assist with cross-traffic func-tion (Ypage 70)
RSTEER CONTROL (Ypage 72)
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. Pay particular attention to theinformation regarding tires, recommendedminimum tire tread depths etc. in the "Wheelsand tires" section (Ypage 293).
In wintry driving conditions, always use wintertires (M+S tires) and if necessary, snow
chains. 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 236) anddisplay messages which may be shown in theinstrument cluster (Ypage 206).
Brakes
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.
