WARNING
•If you do not pay attention to the warning lights coming on and
the corresponding descriptions and warning notes, this may result
in severe body injuries or major vehicle damage.
•The engine compartment of your car is a hazardous area. There
is a risk of injuries, scalding, accid ents and fire when working in the
engine compartment, e.g. inspecting and replenishing oil and other
fluids. It is also essential to observe all warnings ⇒page 210.
Note
•Arrangement of the indicator lights depends on the model and model
version. The symbols shown in the following functional description are to
be found as indicator lights in the instrument cluster.
•Operational faults are shown in the instrument cluster as red symbols
(priority 1 - danger) or yellow symbols (priority 2 - warning).

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
There is a fault in the system if the warning light does not go out or comes
on or flashes while driving
⇒. This also applies if the warning light
does not come on after the ignition is switched on.
The following text will be displayed in the information display*:
AIRBAG FAULT
The functionality of the airbag system is also monitored electronically,
when one airbag has been switched off.
The passenger front airbag and also possibly the passenger side
airbag which have been switched off using the vehicle system tester:
•The warning light lights up for 3 seconds after switching on the igni-
tion and then flashes for 12 seconds afterwards in 2 second intervals.
The passenger front airbag and also possibly the passenger side
airbag which have been switched off using the switch (for switching
off airbags)* in the end face of the dash panel on the front passenger
side:
•The warning light comes on for 3 seconds after the ignition has
been switched on.
•Switching off airbags is indicated in the middle of the dash panel by the
lighting up of the indicator light (airbag switched off)
⇒ page 164.
WARNING
Have the airbag system checked immediately by a specialist
garage if a fault exists. Otherwise, there is a risk of the airbag not
being activated in the event of an accident.
Note
Further information about switching off airbags ⇒page 163, “Deactivating
an airbag”.
Diesel particle filter* (diesel engine)
In the diesel particle filter the resulting soot particles are
collected and burnt during the combustion of diesel fuel.
Code 7GG on the vehicle data sticker ⇒fig. 16 indicates that
your vehicle is equipped with a diesel particle filter. The vehicle
data sticker ⇒page 263, fig. 195 is located on the floor of the
luggage compartment and is also stated in the Service schedule.
The soot particles, which result from the combustion of diesel fuel, are
collected in the diesel particle filter . If the diesel particle filter is added, it
is automatically cleaned during suitable operating conditions. If the engine
control unit detects that the operating conditions for a regeneration
(combustion of deposited soot particles) of the diesel particle fiter are not
optimal, e.g. slow city driving, a warning light in the instrument cluster is
illuminated
.
In order to clean the diesel particle filter, the vehicle should be driven at an
even speed of at least 60 km/h for 15 minutes. The diesel particle filter is

most effectively cleaned if the vehicle is driven in the 4th or 5th gear within
the range of 2 000 to 3 000 rpm.
If these conditions are not met, the warning light
does not go out and
after 10 minutes the warning light begins to flash. ENGINE FAULT
WORKSHOP! is shown in the information display. Afterwards the engine
control unit shifts the engine into the emergency mode, which only has a
reduced power output. After switching the ignition off and on again the
warning light
comes on.
Have the vehicle inspected without delay by your specialist garage.
WARNING
•Please pay attention to the traffic regulations and speed limits.
•The diesel particle filter achieves very high temperatures.
Therefore do not park at points where the hot filter comes into
direct contact with dry grass or other combustible materials - risk
of fire!
•Use neither protective paint for chassis nor anti-corrosion
agent, in order to treat the exhaust system, the heat shields or the
diesel particle filter. The high temperatures can cause the coating
to ignite!
Note
•It is prohibited to use biofuel (RME) and diesel fuel mixture for diesel
vehicles which are fitted with diesel particle filter.
•When using diesel fuel with high sulphur content the life of the diesel
particle filter is clearly reduced. A specialist garage will be able to tell you
which countries offer only diesel fuel with high sulphur content.
Seat belt warning light*
The warning light comes on after the ignition is switched on as a
reminder to fasten the seat belt.
If the seat belts are not fastened when the speed of the car increases to
more than 25km/h, the warning light flashes and an acoustic warning
signal sounds for approx. 90 seconds.
The following text will be displayed in the information display*:
FASTEN SEAT BELT
