take up to 25 minutes. Typically it
needs between seven and
12 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.
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 be
indicated by control indicator %.
Simultaneously a warning message or warning code appears in the Driver
Information Centre.
% illuminates when diesel particle
filter is full. Start cleaning process as
soon as possible.
% flashes when diesel particle filter
has reached the maximum filling
level. Start cleaning process
immediately to avoid damage to the
engine.
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.
If g illuminates additionally,
cleaning is not possible, seek the
assistance of a workshop.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
The control indicator % extinguishes
as soon as the self-cleaning
operation is complete.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on pages 3 168, 3 230 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.
138Driving and operatingElectronic driving
programmes ■ Following a cold start, the operating
temperature programme increasesengine 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.
■ When starting off in snowy or icy conditions or on other slippery
surfaces, the electronic
transmission control selects a
higher gear automatically.
Kickdown If the accelerator pedal is presseddown completely in automatic mode, the transmission shifts to a lower gear
depending on engine speed.Fault
In the event of a fault, g illuminates.
Additionally a code number or a
vehicle message is displayed in the
Driver Information Centre. Vehicle
messages 3 100.
The transmission no longer shifts automatically. Continued travel is possible with manual shifting.
Only the highest gear is available.
Depending on the fault, 2nd gear may also be available in manual mode.
Shift only when vehicle is at a
standstill.
Have the cause of the fault remedied by a workshop.
Interruption of power
supply
In the event of an interruption of
power supply, the selector lever
cannot be moved out of the P
position. The ignition key cannot be
removed from the ignition switch.If the vehicle battery is discharged,
start the vehicle using jump leads
3 215.
If the vehicle battery is not the cause
of the fault, release the selector lever.
1. Apply the parking brake.
2. Release the selector lever trim from the centre console; Poke
with a finger into the leather
socket in front of the selector lever
and push the trim upwards at the
front rim from below, as shown in
the illustration. Rotate trim to the
left.
142Driving and operating
Rocking the vehicleRocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud or snow. Move the selector lever between R and D in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking
The most recently engaged gear (see transmission display) remains
engaged when switching off ignition.
With N, no gear is engaged.
Therefore always apply the parking
brake when switching off ignition. If
parking brake is not applied, P flashes
in the transmission display and the
key cannot be removed from the
ignition switch. P stops flashing in the
transmission display as soon as the
parking brake is slightly applied.
When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.Tyre pressure monitoring
system
To start the sensor matching process of the tyre pressure monitoring
system, the selector lever must be
moved and hold in position N for
five seconds. P illuminates in the
transmission display to indicate that
the sensor matching process can be
started.
Tyre pressure monitoring system
3 200.
Manual mode
If a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, the
shift is not executed. This prevents
the engine from running at too low or
too high an engine speed. A warning
message is displayed in the Driver
Information Centre. Vehicle
messages 3 100.
If engine speed is too low, the
transmission automatically shifts to a
lower gear.If engine speed is too high, the
transmission only switches to a higher gear via kickdown.
When + or - is selected in automatic
mode, the transmission switches to
manual mode and shifts accordingly.
Gear shift indication R with a number next is indicated,
when gear shifting is recommended
for fuel saving reasons.
Shift indication appears only in
manual mode.
Electronic driving
programmes ■ Following a cold start, the operating
temperature programme increasesengine speed to quickly bring the
catalytic converter to the required
temperature.
■ The adaptive programme tailors gearshifting to the driving
conditions, e.g. greater load or
gradients.
