Driving and operating141Diesel particle filterAutomatic cleaning process
The diesel particle filter system filters
harmful 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 twelveminutes. 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 manual cleaning
process
Under certain driving conditions, e.g.
short 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 beindicated by % and a warning
message in the Driver Information
Centre.
% with a warning message
illuminates when diesel particle filter
is full. Start cleaning process as soon as possible.
% with a warning message flashes
when diesel particle filter has reached
the maximum filling level. Start
cleaning process immediately to
avoid damage to the engine.
Activate manual cleaning process
To activate cleaning process,
continue driving, keep engine speed
above 2000 revolutions per minute.
Shift down if necessary. Diesel
particle filter cleaning is then started.
Cleaning takes place quickest at high engine speeds and loads.
The control indicator % extinguishes
as soon as the self-cleaning
operation is complete. Keep on
driving until self-cleaning operation is
complete.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning process not possible
If cleaning is not possible for anyreasons, Z illuminates and a warning
message appears in the Driver
Information Centre. Engine power
may be reduced. Seek the assistance
of a workshop immediately.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.

Vehicle care211Towing
Towing the vehicle
Disengage cap by using a
screwdriver and remove.
The towing eye is stowed with the vehicle tools 3 194.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for towing and not for recovering the
vehicle.
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Transmission in neutral.
Caution
Never tow a vehicle equipped with All Wheel Drive (AWD) with the
front or rear tyres on the road. If
you tow a vehicle equipped with
AWD while the front or rear tyres
are rolling on the road, the drive
system in the vehicle could be
severely damaged. When towing
vehicles equipped with AWD, all
four tyres must not be in contact
with the road.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation system 3 126 and
close the windows.
