Operating safety
Important safety notes
GWARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or
system failures. There isarisk of an accident.
Always have the prescribed service/
maintenance work as well as any required
repairs carried out ataqualified specialist
workshop.
GWARNING
If you switch off the ignition while 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.You will require considerably
more effort to steer and brake. There isarisk
of an accident.
Do not switch off the ignition while driving.
GWARNING
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. Asaresult, 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.
24Introduction

Never tamper with the wiring as well as
electronic components or their software. You
shouldhave all work to electrical and
electronic equipment carried out ataqualified
specialist workshop.
!There isarisk of damage to the vehicle if:
Rthe vehicle becomes stuck, e.g. onahigh
curb or an unpaved road
Ryou drive too fast over an obstacle, e.g.
acurb orahole in the road
Raheavy object strikes the undercarriage
or parts of the chassis.
In situations like this, the body,the
undercarriage, chassis parts, wheelsor
tires could be damaged withoutthe
damage being visible. Components
damaged in this way can unexpectedly fail
or, in the case of an accident, no longer
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 catch fire.

immediately ataqualified specialist
workshop. If on continuing your journey
you noticethat driving safety is impaired,
pull over and stop the vehicle immediately,

RSeat belts
RChild restraint systems
RLATCH-type (ISOFIX) child seat securing
system
Additional protection is provided by:
RSRS (Supplemental Restraint System)
RNECK-PRO head restraints/NECK-PRO

RPRE-SAFE®
RAir bag system components with:
-PASSENGER AIR BAG OFF indicator lamp

Safety

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

such as stickers to them, the air bags may not
function correctly. There is an increased risk
of injury.

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.
