Protection of the environment
General notes
HEnvironmental note
Daimler's declared policy is one of
comprehensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and inamanner
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
environmentally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors:
Roperating conditionsofyour 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.
Raregularly 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
startingthe engine.
Rdo not warm up the engine when the vehicle
is stationary.
Rdrive carefully and maintainasafe distance
from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each gear
only up toof its maximum engine speed.
Rswitch off the engine in stationary traffic.
Rkeep an eye on the vehicle's fuel
consumption.
Environmental concerns and
recommendations
Wherever the operating instructions require
you to dispose of materials, first try to
regenerate or re-use them. Observe the
relevant environmental rules and regulations
when disposing of materials. In this way you
will help to protect the environment.
Product information
Mercedes-Benz recommends that you use
genuine Mercedes-Benz parts, conversion
parts and accessories that have been
approved for your vehicle.
Mercedes-Benz tests genuine parts as well as
conversion parts and accessories that have
been specifically approved for your vehicle for
their reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Therefore,
Mercedes-Benz accepts no responsibility for
the use of such parts in Mercedes-Benz
vehicles. This is also the case, even if they
have been independently or officially
approved. The use of non-approved parts
could affect your vehicle's operating safety.
Genuine Mercedes-Benz parts, approved
conversion parts and accessories are
available from any authorized Mercedes-Benz
Center. Here, you will receive advice about
permissible technical modifications, and the
parts will be professionally installed.

RNo modifications of any kind may be made
to any components or wiring of the SRS.
RDo not change or remove any component
or part of the SRS.
RDo not install additional trim material,seat
covers, badges, etc. to the:
-padded steering wheel boss
-knee bag covers
-front-passenger air bag cover
-outer side of front seat bolsters
-side trim next to the rear seat backrest
-roof lining trim
RDo not install additional electrical/
electronic equipment on or near SRS
components and wiring.
RKeep area between air bags and occupants
free of objects (e.g. packages, purses,
umbrellas, etc.).
RDo not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may be thrown around in
the vehicle and cause head and other
injuries when the window curtain air bag is
deployed.
RAir bag system components willbehot after
an air bag has inflated. Do not touch them.
RNever place yourfeet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
RImproper repairwork on the SRS creates a
risk of rendering the SRS inoperative or
causing unintended air bag deployment.
Work on the SRS must thereforeonly be
performed by qualified technicians.
Contact an authorized Mercedes-Benz
Center.
RFor your protection and the protection of
others, when scrapping the air bag unit or
ETD, our safety instructions must be
followed. These instructions are available
from any authorized Mercedes-Benz
Center.
RGiven the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, Mercedes-Benz
strongly recommends that you inform the
subsequent owner that the vehicle is
equipped with SRS. Also, refer them to the
applicablesection in the Operator's Manual.
Air bags
Important safety notes
GWARNING
If you modify the air bag covers or affix objects
such as stickers to them, the air bags may not
function correctly. There is an increased risk
of injury.
Never modify the air bag covers or affix
objectstothem.
GWARNING
Using unsuitable seat covers could restrictor
even preventdeployment of the air bags
integrated into the seats. Consequently, the
air bags cannot protectvehicle occupantsas
they are designed to do. In addition, the
function of the air bag deactivation system
could be restricted. This poses an increased
risk of injury or even fatal injury.
You should only use seat coversthat have
been approved for the respective seat by
Mercedes-Benz.
GWARNING
The air bag parts are hot after the airbag has
been deployed. There isarisk of injury.
Do not touch the air bag parts. Have the
deployed air bags replaced ataqualified
specialist workshop as soon as possible.

The pelvis air bags deploy next to and below
the outer seat cushions. They are deployed:
Ron the side on which an impact occurs
Rat the start of an accident withahigh rate
of lateral vehicle deceleration or
acceleration,e.g. inaside impact
Rindependently of the use of the seat belt
Rindependently of the front air bags
Rindependently of the ETDs
If the vehicle rolls over,the pelvis air bags are
generally not deployed. Exception: if the
system detectshigh vehicle deceleration or
acceleration inalateral direction and
determines that deploymentcan offer
additional protection to that providedbythe
seat belt.
Pelvis air bagswill notdeploy in side
impacts which do not exceed the system's
preset deployment thresholds for lateral
acceleration/deceleration.You will then be
protected by the fastened seat belt.
The pelvis air bag on the front-passenger side
is not deployed in the following situations:
ROCS has detected that the front-passenger
seat is unoccupied.
Rthe front-passenger seat belt is not
fastened.
The pelvis air bag on the front-passenger side
will deploy if the front-passenger seat belt is
fastened, regardless of whether the front-
passenger seat is occupied or not.
Window curtain air bags

of protection for the head, but not chest or
arms, of the vehicle occupantsonthe side of
the vehicle on which the impact occurs.
The window curtain air bags are integrated
into the side of the roof frame and deploy in
the area from the A-pillar to the C-pillar.
Window curtain air bags are deployed:
Rat the start of an accident withahigh rate
of lateral vehicle deceleration or
acceleration, e.g. inaside impact

(OCS)
Method of operation
GWARNING
If theindicator lamp illuminates
when an adult or someone larger thanasmall
individual is in the front-passenger seat, have
the front passenger reposition himself or
herself in the seat until the
indicator lamp goes out.
In the event ofacollision, the air bag control
unit will not allow front-passenger front air
bag deployment when the OCS has classified
the front-passenger seat occupant as
weighing as much as or less thanatypical 12-

Rif, on vehicles with DISTRONIC PLUS,the
radar sensor system detectsanimminent
dangerofcollision in certain situations.
Rin critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely.
PRE-SAFE®takes the following measures
depending on the hazardous situation
detected:
Rthe front seat belts are pre-tensioned.
Rthe front-passenger seat is adjusted if it is
in an unfavorable position.
Rvehicles withamulticontour seat or active
multicontour seat: the air pressure in the
side bolsters of the seat cushion and
backrest is increased.
Rif the vehicle skids, the sliding sunroof and
the side windows are closed so that only a
small gap remains.
If the hazardous situation passes without
resulting in an accident,PRE-SAFE®slackens
the belt pre-tensioning. The air pressure in
the side bolsters on the multicontour seat/
active multicontour seat is reduced again. All
settings made by PRE-SAFE®can then be
reversed.
If the seat belts are not released:
XWhen the vehicle is stationary, move the
backrest or seat back slightly.
The seat belt pre-tensioningisreduced and
the lockingmechanism is released.
Information about seat belt adjustment, a
conveniencefunction integrated into PRE-
SAFE®,can be found in the "Seat belt
adjustment" section (Ypage 57).
Seat belts
Important safety notes
GWARNING
The seat belt does not offer the intended level
of protection if the backrest is not in the
upright position. When braking or in the event
of an accident,you could slide underneath the
seat belt and sustain abdomen or neck
injuries, for example. This poses an increased
risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always make sure that the seat
is in the upright position.
GWARNING
Seat belts cannot protect as intended, if:
Rthey are damaged, extremely dirty,
bleached or dyed
Rthe seat belt buckle is damaged or
extremely dirty
Rthe Emergency TensioningDevices or the
belt anchorage has been modified.
Damage caused to seat belts in an accident
may not be visible, e.g. by splinters of glass.
Modified or damaged seat belts can tear or
fail, for example in the event of an accident.
Modified Emergency TensioningDevices may
be deployed unintentionally or fail to be
deployed when required. There is an
increased risk of injury, possibly even fatal.
Never modify seat belts, Emergency
TensioningDevices, seat belt anchorages and
inertia reels. Ensure that seat belts are not
damaged or worn and are clean.
Only use seat belts that have been approved
for your vehicle by Mercedes-Benz.
The use of seat belts and infant and child
restraint systems is required by law in:
Rall 50 states
Rthe U.S. territories
Rthe District of Columbia
Rall Canadianprovinces
Even where this is not required by law,all
vehicleoccupants should correctly fasten
their seat belts before starting the journey.
