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.

Safety

GWARNING
Air bagsare designed to reduce the incidence
of injuriesand fatalities in certain situations:
Rfrontal impacts (driver's and front-
passenger front air bagsand knee bags)
Rside impacts (sideimpact air bags, window
curtainair bags and pelvis air bags)
Rrollover (window curtain air bags)
However, no system available today can
completely eliminate injuries and fatalities.
When the air bags are deployed,asmall
amount of powder is released.The powder
generally does not constituteahealth hazard
and does not indicate that there isafire in the
vehicle. In order to prevent potential
breathing difficulties, you should leave the
vehicle as soon as it is safe to do so. If you
have any breathing difficulty but cannot get
out of the vehicle after the air bag inflates,
then get fresh air by openingawindow or
door.
GWARNING
In order to reduce the potential danger of
injuries caused during the deployment of the
front air bags, the driver and front passenger
must always be correctly seated and wear
their seat belts.
For maximum protection in the event of a
collision, you must always be in the normal
seat position with your back against the
backrest. Fasten your seat belt and make sure
that it is correctly positioned on your body.
As the air bag inflates with considerable
speed and force,aproper seating position
and correct positioning of the hands on the
steering wheel will help to keep you atasafe
distance from the air bag. Occupants who are
not wearing their seat belt, are not seated
properly or are too close to the air bag can be
seriously injured or killed by an air bag, as it
inflates with great force instantaneously:
Rsit with the seat belt fastened correctly and
inaposition that is as upright as possible
with your back against the backrest.
Rmove the driver's seat as far back as
possible, still permittingproper operation
of vehicle controls. The distance from the
center of the driver's chest to the center of
the air bag cover on the steering wheel
must be at least 10 inches (25 cm). You
should be able to accomplish this by
adjusting the seat and steering wheel. If
you have any difficulties, please contact an
authorized Mercedes-BenzCenter.
Rdo not lean your head or chest close to the
steeringwheel or dashboard.
Ronly hold the steeringwheel on the outside.
Placing hands and arms inside the rim can
increase the risk and potential severityof
hand/arm injury if the driver frontair bag
inflates.
Radjust the front-passenger seat as far back
as possible from the dashboard when the
seat is occupied.
Roccupants, especially children,should
never place their bodies or lean their heads
in the area of the door where the side
impact air bag inflates.This could result in
serious or fatal injuries should the side
impact air bag be deployed. Always sit as
upright as possible, wear the seat belt
properly and use an appropriately sized
infant restraint,toddler restraint or booster
seat recommended for the size and weight
of the child.
Failure to follow these instructions can result
in severe injuries to you or other occupants.

Safety
Z

If you sell yourvehicle, it is important that you
make the buyer aware of this safety
information.Besure to give the buyer this
Operator's Manual.
If the air bags are deployed, you will hear a
bang, andasmall amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicatethat there
isafire in the vehicle. The dust might cause
some temporary breathingdifficulty for
people with asthma or other breathing
trouble. To avoid this, you may wish to get out
of the vehicle as soon as it is safe to do so.
You can also open the window to allow fresh
air to enter the vehicle interior. TheSRS
warning lamp lights up.
The air bag installation locationsare
identified by the AIR BAG symbol.
The air bags are deployed if the air bag control
unit detects the need for deployment. Only in
the event of suchasituation will the air bags
provide their supplemental protection.
If the driver and frontpassenger do notwear
their seat belts, it is not possible for the air
bags to provide their supplemental
protection.
In the event of other types of impacts and
impacts below air bag deployment
thresholds, the air bags will not deploy. The
driver and passenger will then be protected
to the extent possible byaproperly fastened
seat belt.Aproperlyfastened seat beltisalso
needed to provide the best possible
protection inarollover.
Air bags provide additional protection; they
are not, however,asubstitute for seat belts.
All vehicle occupants must fasten their seat
belts regardless of whether your vehicle is
equipped with air bags or not.
It is important for your safety and that of your
passenger to have deployed air bags replaced
and to have any malfunctioning air bags
repaired. This will help to make sure the air
bags continue to perform their protective
function for the vehicle occupants in the
event ofacrash.
iAfter an air bag has been deployed, have
the vehicle towed to the nearest qualified
specialist workshop, even if your vehicle is
ready to drive.
Front air bags
Driver's air bagdeploysinfront of the
steering wheel; front-passenger front air
bagdeploysinfront of and above the glove
box.
The front air bags increase protection for the
driver's and front passenger's head and
chest.
They are deployed:
Rat the start of an accident withahigh rate
of vehicle acceleration or deceleration in a
longitudinal direction
Rin the event of certain frontal impacts
Rif the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
Rdepending on whether the seat belt is being
used
Rindependently of other air bags in the
vehicle
If the vehicle rolls over, the front air bags are
generally not deployed.
Your vehicle has adaptive, two-stage front air
bags. The air bag control unit evaluates
vehicle deceleration or acceleration in the
event ofacollision. In the first deployment
stage, the front air bag is filled with part of the

Driving safety systems
Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
RABS (Anti-lockBrakingSystem)
(Ypage 66)
RBAS (BrakeAssistSystem) (Ypage 67)
RBAS PLUS (BrakeAssistSystem Plus)
(Ypage 67)
RESP®(ElectronicStabilityProgram)
(Ypage 68)
REBD (ElectronicBrake forceDistribution)
(Ypage 71)
RADAPTIVE BRAKE (Ypage 72)
RPRE-SAFE®Brake (Ypage 72)
Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are
responsible for the distance to the vehicle in
front,for vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road, weather and traffic
conditionsand maintainasafe distancefrom
thevehicle in front. Drive carefully.
iThe driving safety systems describedonly
work as effectivelyaspossible when there
is adequatecontactbetween thetires and
theroad surface. Pleasepay special
attentiontothenotesontires,
recommendedminimumtire tread depths,
etc.(Ypage 334).
In wintry drivingconditions, always use
winter tires (M+S tires) and if necessary,
snowchains. Only in this way will the
drivingsafetysystems described in this
section work as effectively as possible.
ABS (Anti-lock BrakingSystem)
Important safety notes
iObserve the "Importantsafetynotes"
section(Ypage 66).
GWARNING
If ABSisfaulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully.Have ABS checked
immediately ataqualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Ypage 267) and
displaymessages which may be shown in the
instrument cluster (Ypage 238).
ABS regulates brake pressure in suchaway
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.

EBD (electronic brake force
distribution)
iObserve the "Important safety notes"
section (Ypage 66).
GWARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked ataqualified
specialist workshop.
Observe information regarding indicator and
warning lamps (Ypage 267) as well as
displaymessages (Ypage 240).
