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.
Exhaust gas particulate filter
Principle
The exhaust gas particulate filter collects soot
particles. The soot particles are burned at high
temperatures to clean the exhaust gas particu-
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.
▷ Activate Sport program.
▷ If possible, drive at varying speeds.

Vehicle laminated glass
The vehicle laminated glass provides complete
protection against the harmful effects of ultra-
violet radiation on the skin.
Mobile radio in the vehicle
Warning
Vehicle electronics and mobile communica-
tion devices can influence one another. There
is radiation due to the transmission oper-
ations of mobile communication devices.
There is a risk of injury or risk of damage
to property. If possible, in the car's interior
only use mobile communication devices such
as mobile phones with a direct connection to
an external antenna or the Personal eSIM in
order to prevent mutual interference and to
deflect radiation from the vehicle interior.
Aquaplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as aquaplan-
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Driving through water

When driving through water, follow the follow-
