15 Introduction
Operating safety
Operating safety
Proper use of the vehicle
Proper use of the vehicle requires that you
are familiar with the following information
and rules:

the safety precautions in this manual

the “Technical data” section in this
manual

traffic rules and regulations

motor vehicle laws and safety stan-
dards
Warning!G
Work improperly carried out on electronic
components and associated software could
cause them to cease functioning. Because
the vehicle’s electronic components are in-
terconnected, any modifications made may
produce an undesired effect on other sys-
tems. Electronic malfunctions could seri-
ously impair the operating safety of your
vehicle.
See an authorized Mercedes-Benz Center
for repairs or modifications to electronic
components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function while the
engine is running. You should therefore nev-
er turn off the engine while driving.
Warning!G
Heavy blows against the vehicle underbody
or tires/wheels, for example when running
over an obstacle, road debris or a pothole,
may cause serious damage and impair the
operating safety of your vehicle. If you feel a
sudden significant vibration or ride distur-
bance, or you suspect that damage to your
vehicle has occurred, you should turn on
your hazard warning flashers, carefully slow
down, and drive with caution to an area
which is a safe distance from the road.
Inspect the vehicle underbody and
tires/wheels for possible damage. If the ve-
hicle appears unsafe, have it towed to the
nearest authorized Mercedes-Benz Center
or other qualified maintenance or repair fa-
cility for further inspection or repairs.
Warning!G
Various warning labels are attached to your
vehicle. These warning labels are intended
to make you and others aware of various
risks. You should not remove any of these
warning labels unless explicitly instructed to
do so by information on the label itself. Re-
moval of any of these labels may cause you
and others to be unaware of certain risks
which may result in an accident and/or per-
sonal injury.

35 Safety and Security
Occupant safety
Warning!G
Modifications to or work improperly con-
ducted on restraint systems (such as seat
belts and anchors, Emergency Tensioning
Devices (ETDs), seat belt force limiters or air
bags) or their wiring, as well as tampering
with interconnected electronic systems, can
lead to the restraint systems no longer func-
tioning as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy inadvert-
ently or fail to deploy in accidents although
the deceleration threshold for air bag de-
ployment is exceeded. Therefore, never
modify the restraint systems. Do not tamper
with electronic components or their soft-
ware.
Warning!G
In the event that the =indicator lamp
comes on during driving or does not come
on at all, the SRS self-check has detected a
malfunction. For your safety, we strongly
recommend that you contact an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not deploy when needed in an accident,
which could result in serious or fatal injury,
or it might deploy unexpectedly and unnec-
essarily which could also result in injury.
In addition, improper work on the SRS
creates a risk of rendering the SRS inopera-
tive or causing unintended air bag deploy-
ment. Work on the SRS must therefore only
be performed by qualified technicians. Con-
tact an authorized Mercedes-Benz Center.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.
