Hot exhaust system
Warning
High temperatures can occur underneath the
body, for instance caused by the exhaust
system, while driving. Contact with the ex-
haust system can cause burns. There is a risk
of injury. Do not touch the exhaust system,
including the exhaust pipe, when hot.
Warning
If combustible materials such as leaves or
grass come in contact with hot parts of the
exhaust system, these materials can ignite.
There is a risk of fire and an injury hazard.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that no combustible materials can come in
contact with hot vehicle parts while driving, in
Neutral or during parking.

late filter as necessary.
General information
During several minutes of cleaning the follow-
ing may occur:
▷
Temporarily, the engine may run less
smoothly.
▷
A somewhat higher RPM is necessary to
reach usual power development.
▷
A slight smoke formation coming from the
exhaust system, even after the engine is
switched off.
▷
Noises such as those caused by the radia-
tor fan running, even several minutes after
the engine is switched off.
Overrun of the radiator fan for several minutes
is normal even after short trips.
Condensation detected in drive system
Various drive profiles ensure that the drive sys-
tem functions properly. A driving style with
consistently low loads can negatively affect
overall functionality (e.g., condensation forma-
tion in the drive system). Occasionally running
the engine longer with higher loads can coun-
teract this.
The next time you drive outside of town, pro-
ceed as follows for around 30 minutes:
For a gasoline engine:
▷
Deactivate the speed control system.
