Particulate filter (diesel engines)
The particulate filter eliminates soot from
emissions. The particles accumulate in the
filter where they are normally burned off.
If the warning lamp is illuminated, the fil-
ter is obstructed by soot.
In order for the filter to clean itself (if the traf-
›››
fic conditions
so permit) it is essential
to drive for at least 15 minutes (or until the
warning lamp switches off) with 4th or 5th
gear engaged (automatic gearbox: position
S) at a minimum speed of 60 km/h (37 mph)
with the engine speed between
1,800-2,500 rpm.
The warning lamp switches off once the
filter has been successfully cleaned.
If the cleaning process is not successful, the
warning lamp does not switch off and the
warning lamp starts to flash.
The informative display indicates:
Diesel particulate filter. Instruction Manual!
The engine control unit allows driving to con-
tinue in an emergency program. When
switching the ignition off and on again, the
warning lamp also illuminates.

Instruments and warning lamps
WARNING
●
The particulate filter attains very high tem-
peratures. Therefore, do not park the vehicle
in places where the exhaust pipe could come
into contact with dry grass or with highly-
flammable materials. Risk of fire!
CAUTION
While the warning lamp is lit up, the fuel
consumption is high, and in certain condi-
tions, the engine power is reduced.
Note
In order for the particulate filter to burn off
●
soot in a correct manner, avoid carrying out
frequent short journeys.
●
Using diesel fuel with a high sulphur count
can considerably reduce the useful life of the
particulate filter. The specialised service pro-
vides information about the countries where
fuel with a high sulphur content is used.
Fuel reserve
The warning lamp illuminates when ap-
proximately only 7 litres of fuel remain in the
tank
The informative display indicates:
Refuel! Fuel range...km...(miles)
Note
The message on the display switches off only
after refuelling and carrying out a short jour-
ney.
Airbag system
If the warning lamp is lit up, there is a
fault in the airbag system.
The informative display indicates:
Airbag fault!
The airbag system availability is controlled
electronically, regardless of whether an air-
bag is disabled.
If the front airbag, side airbag, head protec-
tion airbag or the belt tensioner are disabled
using the diagnostics system:
●
After switching on the ignition, the warn-
ing lamp illuminates for about 4 seconds and
flashes for another 12 seconds.
The informative display indicates:
Airbag/belt tensioner disabled!
