Restart of the engine by the stop- start system
The selector lever must be in neutral to enable an automatic restart.
If one of the following conditions occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system.
● The stop-start system is manually deactivated
● the bonnet is opened
● the driver's seat belt is unfastened and the driver's door

If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during restart might be noticeable.
Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply the electrical parking brake.
Pull switch m.
The electric parking brake is
applied when control indicator
m illuminates 3 85.
For maximum force, e.g.
parking with a trailer or on
inclines, pull switch m twice.
● Switch off the engine.

130Driving and operatingIf cleaning of the filter is required andprevious driving conditions did not
enable automatic cleaning, it will be
indicated by control indicator %
3 88.
% illuminates, accompanied by a
warning chime, 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. A warning chime sounds
every 3 minutes until the cleaning
process is complete.
Cleaning process To activate the cleaning process,
continue driving, keeping engine
speed above 2000 revolutions per
minute. Shift down if necessary.
Diesel particle filter cleaning is then
started.
If control indicator Z illuminates
additionally in the instrument cluster
when the engine is running, there
may be a fault in the diesel particlefilter 3 84. Cleaning is not possible,
seek the assistance of a workshop
immediately.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.
Do not switch off the engine until the
cleaning process is complete. This is
indicated by the extinguished control
indicator %.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed 3 207 could damage the catalytic
converter or electronic
components.
Unburnt fuel 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.
