Protecting the environment
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

have not been approved by Mercedes-Benz.This could lead to malfunctions in safety-rele-vant systems, e.g. the brake system. Use onlygenuine Mercedes-Benz parts or parts of equalquality. Only use tires, wheels and accessoriesthat have been specifically approved for yourvehicle.

Rmalfunctions and defects in important sys-tem components, e.g. lights, brakes
Rvehicle reactions and operating conditionsin special driving situations, e.g. air bagdeployment, intervention of stability controlsystems
Rambient conditions, e.g. outside tempera-ture
This data is of an exclusively technical natureand can be used to:
Rassist in recognizing and rectifying malfunc-tions and defects
Ranalyze vehicle functions, e.g. after an acci-dent
Roptimize vehicle functions
The data cannot be used to trace the vehicle'smovements.
When your vehicle is serviced, technical infor-mation can be read from the event data mem-ory and malfunction data memory.
Services include, for example:
Rrepair services
Rservice processes
Rwarranties
Rquality assurance
The vehicle is read out by employees of theservice network (including the manufacturer)using special diagnostic testers. More detailedinformation is obtained from it, if required.
After a malfunction has been rectified, theinformation is deleted from the malfunctionmemory or is continually overwritten.
When operating the vehicle, situations areconceivable in which this technical data, inconnection with other information (if neces-sary, under consultation with an authorizedexpert), could be traced to a person.
Examples include:
Raccident reports
Rdamage to the vehicle
Rwitness statements
Further additional functions that have beencontractually agreed upon with the customerallow certain vehicle data to be conveyed bythe vehicle as well. The additional functionsinclude, for example, vehicle location in caseof an emergency.
COMAND/Mercedes me connect
(Canada: TELEAID)
If the vehicle is equipped with COMAND orMercedes me connect, additional data aboutthe vehicle's operation, the use of the vehiclein certain situations, and the location of thevehicle is compiled through COMAND or theMercedes me connect system.
For additional information, please refer to theCOMAND User Manual or Digital Operator'sManual and/or the Mercedes me connectTerms and Conditions.
Event data recorders
USA only:
This vehicle is equipped with an event datarecorder (EDR). This vehicle is equipped withan event data recorder (EDR). The main pur-pose of an EDR is to record, in certain crash ornear crash-like situations, such as an air bagdeployment or hitting a road obstacle, datathat will assist in understanding how a vehi-cle's systems performed. The EDR is designedto record data related to vehicle dynamics andsafety systems for a short period of time, typi-cally 30 seconds or less.
The EDR in this vehicle is designed to recordsuch data as:
RHow various systems in your vehicle wereoperating
RWhether or not the driver and passengersafety belts were buckled/fastened
RHow far (if at all) the driver was depressingthe accelerator and/or brake pedal; and,
RHow fast the vehicle was traveling
These data can help provide a better under-standing of the circumstances in whichcrashes and injuries occur. NOTE: EDR dataare recorded by your vehicle only if a non-triv-ial crash situation occurs; no data are recor-ded by the EDR under normal driving condi-tions and no personal data (e.g. name, gender,age and crash location) are recorded. How-ever, other parties, such as law enforcementcould combine the EDR data with the type ofpersonally identifying data routinely acquiredduring a crash investigation.
Access to the vehicle and/or the EDR is nee-ded to read data that is recorded by an EDR,and special equipment is required. In addition

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.

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.
