Operating safety and vehicle approval
Important safety notes
GWARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at a qualified specialist workshop.
Air bags and pyrotechnic Emergency Tensioning
Devices (ETDs) contain perchlorate material,
which may require special handling and regard
for the environment. The guidelines must be
observed during disposal.
In California, you can find more information on
the Internet at www.dtsc.ca.gov.
Notes on operating the vehicle
There is a risk of damage to the vehicle if:
Rthe vehicle makes contact with the ground,
e.g. on a high curb or a loose road surface
Ryou drive too quickly over an obstacle, e.g. a
curb, speed bump or pothole
Ra heavy object hits the underbody or chassis
component
In these or similar situations, the vehicle body/
frame, the underbody, chassis components,
wheels or tires could be damaged even if this is
not visible from the outside. Components that
have been damaged in this way can unexpect-
edly fail or no longer be able to assimilate the
loads occurring in the event of an accident. If the underbody paneling is damaged, flammable
material, such as leaves, grass or twigs, could
collect between the underbody and underbody
paneling. These materials could ignite if they
remain in contact with hot components of the
exhaust system for an extended period.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is a risk of fire.
