WARNING
Modifications to electronic components, their
software as well as wiring could affect their
function and/or the operation of other net-
worked components. This could in particular
also be the case for systems relevant to
safety. They might not function properly any-
more and/or jeopardise the operational
safety of the vehicle. There is an increased
risk of an accident and injury.
Do not attempt to modify the wiring as well as
electronic components or their software.
Always have work on electrical and electronic
components carried out at a qualified special-
ist workshop.
If you make any modifications to the vehicle
electronics, the general operating permit will be
invalidated.
In the following situations, there is a risk of dam-
age to the vehicle:
R
the vehicle makes contact with the ground,
e.g. on a high kerb or a loose road surface.
R
the vehicle drives too quickly over an obsta-
cle, e.g. a kerb, a speed bump or a pothole.
R
a heavy object hits the underbody or chassis
components.
In these or similar situations, the vehicle body,
the underbody, chassis components, wheels or
tyres could be damaged even if this is not visible.
Components that have been damaged in this
way can fail unexpectedly or, in the event of an
accident, may not absorb the loads that arise as
intended.

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

ticular, remove trapped plant parts or other
flammable material. Contact a qualified spe-
cialist workshop immediately if damage is
detected.
