Operating safetyGWarning!
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.
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.
GWarning!
Heavy blows against the vehicle underbody or
tires/wheels may cause serious damage and
impair the operating safety of your vehicle.
Such blows can be caused, for example, by
running over an obstacle, road debris or a
pothole. If you feel a sudden significant
vibration or ride disturbance, or you suspect
that damage to your vehicle as occurred:
R turn on your hazard warning flashers
R slow down carefully
R 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.
Proper use of the vehicle
Proper use of the vehicle requires that you are
familiar with the following information and
rules:
R the safety precautions in this manual
R the “Technical data” section in this manual
R traffic rules and regulations
R motor vehicle laws and safety standardsGWarning!
Various warning labels are attached to your
vehicle. These warning labels are intended to
make you and others aware of various risks.
Do not remove any of these warning labels
unless explicitly instructed to do so by
information on the label itself. Removing
warning labels may cause you and others to
be unaware of certain risks which may result
in an accident and/or personal injury.
Problems with your vehicle
If you should experience a problem with your
vehicle, particularly one that you believe may
affect its safe operation, we urge you to
contact an authorized Mercedes-Benz Center
immediately to have the problem diagnosed
and corrected if required. If the matter is not
handled to your satisfaction, please discuss
the problem with the Mercedes-Benz Center
management or, if necessary, contact us at
one of the following addresses:
