WARNING
If the vehicle has to be stopped for technical reasons, park it a safe dis-
tance away from moving traffic, switch off the engine and turn on the
hazard warning lights ⇒ page 101.
Coolant level and temperature
If the warning lamp (blue) is lit up, the engine has not yet reached its op-
erating temperature 1)
. Avoid high engine speeds, hard acceleration and
submitting the engine to high loads.
If the warning lamp (red) is lit up or flashing, the coolant temperature is
too high or its level is too low.
The informative display indicates:
Check coolant! Instruction Manual!
Stop the vehicle, switch off the engine, check the coolant level ⇒ page 188
and refill if necessary ⇒ page 188.
If the coolant is situated in the prescribed area, the high temperature may
be due to a fault in the cooling system fan. Check the radiator fan fuse and
replace it if necessary ⇒ page 221, Changing fuses in the engine compart-
ment.
If the warning lamp (red) remains lit up, despite both the coolant level
and the radiator fan fuse being in correct condition, stop the vehicle!
Seek professional help.
WARNING
● If the vehicle has to be stopped for technical reasons, park it a safe
distance away from moving traffic, switch off the engine and turn on the
hazard warning lights ⇒ page 101.
● Take care when opening the coolant reservoir. When the engine is
warm or hot, the system is pressurised – Danger of burns! Wait for the
engine to cool before opening the cover.
● Do not touch the fan. The fan can switch on automatically regardless
of whether the ignition is switched on.
Power steering
If the warning lamp, is lit up there is a fault in the power steering.
The power steering system functions with reduced power steering effect.
Seek professional help.
Stability Control (ESC)
If the control lamp flashes, the ESC is working.
If the warning lamp lights up on ignition the ESC system may have
switched off due to technical reasons. Turn off the ignition and turn it on
again. Upon switching on the ignition again, if the warning lamp has switch-
ed off, this means the ESC is functioning correctly again.
If the warning lamp, is lit up there is a fault in the ESC.

Seek professional help.
Further information ⇒ page 144, Stability system (ESC).
Note
If the battery is disconnected and connected again, the yellow warning
lamp lights up when the ignition is switched on. This warning lamp must
switch off after covering a short distance.
Traction control system (ASR)
If the control lamp
flashes, the ASR is working.
If the warning lamp lights up on ignition the ASR system may have
switched off due to technical reasons. Turn off the ignition and turn it on
again. Upon switching on the ignition again, if the warning lamp has switch-
ed off, this means the ASR is functioning correctly again.
If the warning lamp, remains lit up there is a fault in the ASR.
The informative display indicates: Report No.: Traction control system (ASR)
Seek professional help.
Further information ⇒ page 145, Traction control system (ASR). Anti-lock system (ABS)
If the warning lamp, is lit up there is a fault in the ABS.
The informative display indicates: ABS fault
The brake system alone is operational in the vehicle, without ABS.
Seek professional help.

Bulb fault
The control lamp lights up when there is a fault in a bulb:
● For several seconds after switching on the ignition
● When connecting a faulty bulb
This is indicated on the informative display, e.g.: Check the front right dipped beam headlight!
Note
The rear side lights and number plate light contain several bulbs. The con-
trol lamp lights up only when there is a fault in all the number plate
bulbs or side light bulbs (of a combined tail light). Therefore it is advisable
to regularly check the bulb operation.
Emission control system
If the warning lamp is lit up, there is a fault in the emission system. The
engine control unit allows driving to continue in an emergency program.
Seek professional help.
Preheating (diesel engines)
When you switch on the ignition, the warning lamp lights up. The engine
can be started straight away when the lamp switches off.
If the warning lamp does not light up or if it does not switch off , there is
a fault in the glow plug system. If the warning lamp
starts to flash while driving, there is a fault in the
engine power control electronic system. The engine control unit allows driv-
ing to continue in an emergency program.
Seek professional help.
Engine management system (petrol engines)
If the warning lamp is lit up, there is a fault in the engine management
system. The engine control unit allows driving to continue in an emergency
program.
Seek professional help.
Particulate filter (diesel engines)
The particulate filter eliminates soot from emissions. The particles accumu-
late in the filter where they are normally burned off.
If the warning lamp is lit up, the filter is obstructed by soot.
In order for the filter to clean itself (if the traffic 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
1800-2500 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:

Controls and displays
Diesel particulate filter. Instruction Manual!
The engine control unit allows driving to continue in an emergency program.
When switching the ignition off and on again, the warning lamp also
lights up.
Seek professional help.
WARNING
● The particulate filter attains very high temperatures. 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!
● Always adjust your speed to suit the weather, road, terrain and traffic
conditions. Never be encouraged, by the recommendations shown in the
warning lamps, to fail to respect traffic legislation.
CAUTION
While the warning lamp is lit up, the fuel consumption is high, and in
certain conditions, 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 provides informa-
tion about the countries where fuel with a high sulphur content is used.
Fuel reserve
The warning lamp lights up when approximately only 7 litres of fuel re-
main 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 journey.
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 airbag is disabled.
If the front airbag, side airbag, head protection airbag or the belt tensioner
are disabled using the diagnostics system:
● After switching on the ignition, the warning lamp lights up for around
4 seconds and flashes for another 12 seconds.
The informative display indicates:
Airbag/belt tensioner disabled!
