WARNING
If you switch off the ignitio nwhile driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect.Y ou will require considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving. G
WARNING
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other
networked components. In particular,
systems relevant to safety could also be
affected. As aresult, these may no longer
function as intended and/or jeopardize the
operating safety of the vehicle. There is an
increased risk of an accident and injury.
Never tamper with the wiring as well as
electronic components or their software. You
should have all work to electrical and
electronic equipment carried out at aqualified
specialist workshop.
! There is arisk of damage to the vehicle if:
R the vehicle becomes stuck,e .g. onahigh
cur boranu npavedroad
R yo ud rive too fas tover an obstacle, e.g.
ac urb or ahole in the road
R ah eavy object strikes the undercarriage
or parts of the chassis
In situations like this, the body ,the
undercarriage, chassi sparts, wheels or
tires coul dbedamaged without the
damage being visible .Components
damaged in this way can unexpectedly fail
or, in the case of an accident ,nolonger
withstand the strain they are designed to.
If the underbody paneling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody paneling. If
these materials come in contact with hot parts of the exhaust system for an
extended period, they can catchf
ire.
In such cases, have the vehicle checked
and repaired immediately at aqualified
specialist workshop. If on continuing your
journey you notice that driving safety is
impaired, pull over and stop the vehicle
immediately, paying attention to road and
traffic conditions. In such cases, visit a
qualified specialist workshop. Declarations of conformity

WARNING
Modifications to the restraint system scould
result in them not functioning properly any
more. The restraint system scould then no longer protect vehicle occupants as they are
designed to do and could fail in the even

an acciden toractivat eunexpectedly, for
example. Ther eisanincreased risk of injury.
Never modify part softherestraint systems.
Do no tattemp ttomodify the wiring as well as
electronic components or their software.
If it is necessary to modify an air bag system
to accommodat eaperson with disabilities,
contact an authorized Mercedes-Benz center.

In this section ,you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint system consist sof:
R Seat belts
R Child restraint systems
R LATCH-type (ISOFIX) child seat securing
system
Additional protection is provided by:
R SRS (Supplemental Restraint System)
R Air bag system components with:
-PASSENGER AIR BAG OFF indicator lamp
- Front-passenger seat with Occupant
Classification System (OCS)
Although the systems are independent ,their
protective functions work in conjunction with
each other. Not all air bags are always
deployed in an accident.

decisive role in the deployment of an air bag,
nor do they provide an indication of air bag
deployment.
The vehicle may be deformed significantly,
e.g. the hood or the fender ,without an air bag
being deployed. This is the case if only parts
which are relatively easily deformed are
affected and the rate of deceleration is not
high. Conversely, air bags may be deployed
even though the vehicle suffers only minor
deformation. This is the case if, for example,
very rigid vehicle parts such as longitudinal
body members are hit, and sufficient
deceleration occurs as aresult.
i The fron tEmergenc yTensioning Devices
can only be triggered if the seat belt
tongues on the fron tseats are correctly
engaged in the seat belt buckles.
i Not all air bags are deployed in an
accident. The differen tair bag systems
work independently of each other.
How the air bag system work sis
determined by predictin gthe severity of
the accident ,especially vehicle
deceleration or acceleration, and the type
of accident:
R head-on collision
R side impact
R rollover

and air bags G
WARNING
R Damaged seat belts or seat belts that have
been subjected to stress in an accident
must be replaced. Their anchorin gpoints
must also be checked. Only use seat belts
installed or supplied by an authorized
Mercedes-Ben zCenter.
R Air bags and pyrotechnic Emergency
Tensionin gDevices (ETDs) contain
perchlorat ematerial, which may require
special handlin gand regar dfor the environment. Check your national disposal
guidelines. In California, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
R Air bags and ETD sare designed to function
on aone-time-only basis. An air bag or ETD
that has deployed must be replaced.
R Do not pass seat belts over sharp edges.
They could tear.
R Do not make any modification that could
change the effectiveness of the seat belts.
R Do not bleach or dye seat belts ,asthis may
severely weaken them. In acrash, the ymay
not be able to provide adequate protection.
R Do not make any modifications to the SRS
wirin gorc omponents.
R Do not modif yorremove any components

- front-passenger air bag cover
- outer side of front seat bolsters
- outer seat bolsters of the rear bench seat
backrest
- roof frame trim
R Do not install additional electrical/
electronic equipment on or near SRS
components and wiring.
R Keep the area between the air bags and
occupant sfree of object s(e.g. packages,
handbags, umbrellas etc.).
R Do not hang any objects such as coat
hangers on the coat hooks or the grab
handle above the door. These items may be
thrown around in the vehicle and cause
