Driving and operating137
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 3 171, 3 239 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.

Deactivation
Press B; LED in the button
extinguishes and a message pops-up in the Driver Information Centre.
Each time the engine is started, City
mode is deactivated.
Overload If the steering in City mode is heavily
loaded, e.g. in long parking
manoeuvres or heavy city traffic, the
system is deactivated for overheating
protection. Steering operates in
normal mode until City mode
activates automatically.
FaultIn the event of a fault in the system,
control indicator c illuminates and a
message is displayed in the Driver
Information Centre.
Vehicle messages 3 103.
System calibration If control indicators c and b
illuminate simultaneously, a
calibration of the power steering
system is necessary. This can occur
e.g. when turning the steering wheel
for one rotation with ignition switched
off. In this case, switch on ignition and turn steering wheel once from lock to
lock.
If control indicators c and b do not
extinguish after calibration, seek the
assistance of a workshop.Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds of approx. 20 to
120 mph. Deviations from the stored
speeds may occur when driving uphill or downhill.
