If you plan to operate your vehicle in foreign

R Service

facilities or replacement parts may
not be readily available.

the use of leaded fuels will damage the

R Gasoline may have a considerably lower
octane rating, and improper fuel can cause
engine damage. Operating safety
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
