parking, no flammable materials can come into
contact with hot vehicle parts.
General driving information
Closing the tailgate
Safety note
Exhaust gas particle filter
Principle
The exhaust gas particle filter collects soot parti‐
cles. The soot particles are burned at high tem‐
peratures to clean the exhaust gas particle filter
as necessary.
WARNING
When open, the tailgate protrudes above the
vehicle and in the event of an accident, or when
braking or carrying out evasive manoeuvres,
can endanger vehicle occupants and other road
users or damage the vehicle. There is also a
risk of exhaust fumes entering the interior of
the vehicle. There is a risk of injury or material
damage. Do not drive with the tailgate open.
General
The cleaning process takes a few minutes, dur‐
ing which the following may occur:
▷ The engine may temporarily run a little
roughly.
▷ A slightly higher engine speed may be re‐
quired to achieve the usual power output.
Driving with the tailgate open
If there is no alternative to driving with the tail‐
gate open:
▷ There may be a small amount of smoke from
the exhaust, even after stopping the engine.
▷ Close all the windows and the glass sunroof.
▷ Adjust the blower to a high setting.
▷ Maintain a moderate speed.
▷ Noise, for example caused by the radiator fan
running, may be heard, even some minutes
after stopping the engine.
It is normal for the radiator fan to keep running
for several minutes, even after short trips.
Hot exhaust system
Petrol engine: Cleaning the exhaust
gas particle filter while driving
Various driver profiles ensure that the exhaust
gas particle filter is self-cleaning. If, in addition to
the self-cleaning function, the exhaust gas parti‐
cle filter needs to be actively cleaned while driv‐
ing, a Check Control message is displayed.
WARNING
High temperatures may occur under the vehicle
body during driving, for example because of the
exhaust system. Contact with the exhaust sys‐
tem can lead to burns. There is a risk of injury.
Do not touch the hot exhaust system, including
the exhaust pipe.
Proceed as follows the next time you drive out‐
side of built-up areas for around 30 minutes:
▷ Deactivate cruise Control systems.
WARNING
▷ Take your foot off the accelerator repeatedly
and allow the vehicle to roll in overrun mode,
see page 268.
If flammable materials, for example leaves or
grass, come into contact with hot parts of the
exhaust system, these materials can catch fire.
There is a risk of fire and injury. Never remove
the heat shields fitted here or apply underseal
to them. Make sure that when driving, idling or
▷ If possible, drive at alternating speeds.
