Control indicators The control indicators described are
not present in all vehicles. The
description applies to all instrument
versions. Depending on the
equipment, the position of the control indicators may vary. When the
ignition is switched on, most control
indicators will illuminate briefly as a
functionality test.

Start cleaning process immediately to
avoid damage to the engine.
Activate self-cleaning process To activate cleaning process,
continue driving, keep engine speed
above 2000 rpm. Shift down if
necessary. Exhaust filter cleaning is
then started.
Cleaning process is completed more
quickly 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 anyreason, 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.
Caution
Fuel grades other than those listed on pages 3 229, 3 292 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.
264Vehicle careSelect Tyre pressure page under
Vehicle Information Menu ?
3 101.
System status and pressure warnings are displayed by a message
indicating the corresponding tyre in the Driver Information Centre.
The system considers the tyre
temperature for the warnings.
A detected low tyre pressure
condition is indicated by control
indicator w 3 99.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 297.
If w flashes for 60-90 seconds and
then illuminates continuously, there is
a fault in the system. Consult a
workshop.
After inflating, some driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure.
Vehicle messages 3 106.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A temporary spare wheel is not
equipped with pressure sensors. The
tyre pressure monitoring system is
not operational for these wheels.
Control indicator w illuminates. For
the further three wheels the system
remains operational.
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.Operating electronic devices or being close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
Each time the tyres are replaced, tyre pressure monitoring system sensors
must be dismounted and serviced. For the screwed sensor: replace
valve core and sealing ring. For
clipped sensor: replace complete
valve stem.
Vehicle loading status Adjust tyre pressure to load condition
according to the tyre information label or tyre pressure chart 3 297, and
select the appropriate setting in the Tyre load menu in the Driver
Information Centre 3 101. This
setting is the reference for the tyre
pressure warnings.
The Tyre load menu only appears if
the vehicle is at a standstill and the parking brake is applied. On vehicles
with automatic transmission the
selector lever has to be in P.
