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.
driving 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 illumination of % and a
warning message in the Driver Information Centre.
% illuminates along with a warning
message illuminates when diesel
particle filter is full. Start cleaning
process as soon as possible.
% flashes along with a warning
message 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 rpm. Shift down if
necessary. Diesel particle filter
cleaning is then started.
Cleaning takes place quickest at high
engine speeds and loads.
Control indicator % extinguishes as
soon as the self-cleaning operation is
complete. Keep on driving until self-
cleaning operation is complete.Caution
If possible, do not interrupt
cleaning process. Drive until
cleaning is completed to avoid the need for service or repair by a
workshop.
Cleaning process not possible
If cleaning is not possible for anyreasons, control indicator 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.

142Driving and operatingCaution
Fuel grades other than those listedon pages 3 168, 3 229 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
AdBlue
General information
The selective catalytic reduction
(BlueInjection) is a method to
substantially reduce the nitrogen
oxides in the exhaust emission. This
is achieved by injecting a Diesel
Exhaust Fluid into the exhaust
system. The ammonia released by
the fluid reacts with nitrous gases
(NO x) from the exhaust and turns it
into nitrogen and water.
The designation of this fluid is AdBlue
® . It is a non-toxic, non-flammable,
colourless and odourless fluid which
consists of 32% urea and 68% water.9Warning
Avoid contact of your eyes or skin
with AdBlue.
In case of eye or skin contact,
rinse off with water.
Caution
Avoid contact of the paintwork with AdBlue.
In case of contact, rinse off with water.
AdBlue freezes at a temperature of
approx. -11 °C. As the vehicle is
equipped with an AdBlue pre-heater,
the emissions reduction at low
temperatures is ensured. The AdBlue
pre-heater works automatically.
The typical AdBlue consumption is
approx. 2 l per 600 miles, but can also be higher depending on driving
behaviour (e.g. high load or towing).
AdBlue tank The AdBlue tank level can be found in the display menu.
Level warnings
Depending on the calculated range of
AdBlue, different messages are
displayed in the Driver Information
Centre. The messages and the
restrictions are a legal requirement.

146Driving and operatingWhen a gear is engaged, the vehicle
slowly begins to creep when the
brake is released.
Engine braking To utilise the engine braking effect,
select a lower gear in good time when
driving downhill, see manual mode.
Rocking the vehicle Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud or snow. Move the selector
lever between D and R in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking Apply the parking brake and engageP .
The ignition key can only be removed
when the selector lever is in position
P .Manual mode
Move selector lever to position M.
Press button on the selector lever:
<:shift to a higher gear]:shift to a lower gear
If a higher gear is selected when
vehicle speed is too low, or a lower
gear when vehicle speed is too high,
the shift is not executed. This can
cause a message in the Driver
Information Centre.
In manual mode no automatic shifting to a higher gear takes place at high
engine revolutions.
Gear shift indication
The symbol R with a number beside
it is indicated when gearshifting is
recommended for fuel saving
reasons.
Shift indication appears only in
manual mode.
Electronic driving programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● The automatic neutral shift function automatically shifts to
idling when the vehicle is stopped with a forward gear engaged and
the brake pedal is pressed.
● Special programmes automatically adapt the shifting
points when driving up inclines or down hills.
