16 IntroductionOperating 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
standards
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
interconnected, any modifications made
may produce an undesired effect on other
systems. Electronic malfunctions could
seriously 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
never 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 to 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
vehicle appears unsafe, have it towed to the
nearest authorized Mercedes-Benz Center
or other qualified maintenance or repair
facility 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.
Removal of any of these labels may cause
you and others to be unaware of certain
risks which may result in an accident and/or
personal injury.
