After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
Note
In the event of an accident with
airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain time.
Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Exhaust filter
The exhaust filter is a particle filter for diesel and gasoline engines.
Automatic cleaning process
The exhaust filter system filters soot particles out of the exhaust gases.
The system includes a self-cleaning
function that runs automatically
during driving without any notification. The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
conditions and may take up to
25 minutes. Typically it needs
between seven and twelve minutes.
Autostop is not available and fuel
consumption may be higher during
this period. The emission of smells
and smoke during this process is
normal.
System requires cleaning Under certain conditions, e.g. drivingshort distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and
if previous driving conditions did not
enable automatic cleaning, it will be
indicated by a warning message in
the Driver Information Centre.
Driving and operating1692. Close all doors to avoid ammoniafumes entering the interior of the

five minutes.
8. Place the canister on the ground to empty the hose, wait
15 seconds.
9. Unscrew the hose from the filler neck.
10. Mount the protective cap and turn
clockwise until it engages.
Note
