Product Information
Please observe the following in your own best
interest:
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.
We are unable to make an assessment for
other products and therefore cannot be held
responsible for them, even if in individual
cases an official approval or authorization by
governmental or other agencies should exist.
Use of such parts and accessories could
adversely affect the safety, performance or
reliability of your vehicle. Please do not use
them.
Genuine Mercedes-Benz Parts and pre-
approved conversion parts and accessories
are available at any authorized Mercedes-
Benz Center. In addition, you will receive
comprehensive information on permissible
technical modifications and expert
installations. Operator’s Manual

of useful information. We urge you to read it
carefully and familiarize yourself with the
vehicle before driving.
For your own safety and longer service life of
the vehicle, we urge you to follow the

result in damage to the vehicle or personal
injury to you or others. Vehicle damage
caused by failure to follow instructions is not
covered by the Mercedes-Benz Limited

product and ask for your understanding that
we reserve the right to make changes in
design and equipment. Therefore,
information, illustrations, and descriptions in
this

Operator’s Manual might differ from your

operating particular equipment, any
authorized

Mercedes-Benz Center will be glad
to demonstrate the proper procedures.

G
Warning!
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. G
Warning!
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. 22
