16 Introduction
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
(
page 436) in this manual

the traffic rules and regulations

the 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
interconnected, any modification made may
produce an undesired effect on other
systems.
Contact 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 undercar-
riage or tires/wheels, for example when
running over an obstacle, road debris or a
pothole, may cause serious damage and im-
pair the operating safety or your vehicle. If
you feel a sudden significant vibration or
ride disturbance, or you suspect that dam-
age to your vehicle has occurred, you should
turn on your hazard warning flashers, care-
fully slow down, and drive with caution to an
area which is a safe distance from the road.
Inspect the vehicle undercarriage or
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 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.
