Product information
We recommend using genuine Mercedes-
Benz parts as well as conversion parts and
accessories explicitly approved by us for your
vehicle model.
We have tested these parts to determine their
reliability, safety and special suitability for
Mercedes-Benz vehicles. Despite ongoing
market research, Mercedes-Benz is unable to
assess other parts. We cannot therefore be
held responsible for them, even if in individual
cases an official approval or authorization by
governmental or other agencies should exist.
The use of non-approved parts could affect
your vehicle's operating safety. Mercedes-
Benz therefore recommends that you use
genuine Mercedes-Benz parts, conversion
parts and accessories that have been
approved for the type of vehicle. Genuine
Mercedes-Benz parts, approved conversion
parts and accessories are available from any
authorized Mercedes-Benz Center. In
addition, you will receive advice about
permissible technical modifications, and the
parts will be professionally installed.

Operating safety
Safety notes
GWarning
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 when 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 has 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.
