
The warning light
 comes on for a few seconds when the ignition is switched on.
If the ESP helps to stabilise the vehicle (f or example when applying and releasing a
braking force to an individual wheel), then the indicator light
 flashes quickly.
The warning light
 lights up permanently if there is a fault in the ESP system.
The fact that the ESP system operates together with the ABS means that the ESP
warning light will also come on if the ABS system is not operating properly.
If the warning light  comes on immediately after starting the engine, the ESP system
can be switched off for technical reasons. In this case, the ESP system can be switched
on again by switching the igni tion on and off. If the warning light goes out, the ESP
system is fully functional again.
Further information on the ESP page 133, “Electronic stab ility programme (ESP)*”.

Antilock brake system (ABS)

The warning light
 shows the functionality of the ABS.
The warning light comes on for a few seconds after the ignition has been switched on
or when starting the engine. The warning light goes out after an automatic check
sequence has been completed.
A fault in the ABS
The system is not functioning properly if the ABS warning light
 does not go out
within a few seconds after switching on the ignition, does not light up at all or lights up
while driving. The vehicle will only be br aked by the normal brake system. Visit a
specialist garage as quickly as possible and adjust your style of driving to take account
of the fault in the meantime since you will not know the extent of the fault and in how
far the effect of the antilock brakes is affected.
Further information about ABS page 136, “Antilock brake system (ABS)”.
A fault in the entire brake system
If the ABS warning light
 comes on together with the brake system warning light

(handbrake must be released), there is a fa ult not only in the ABS but also in another
part of the brake system .
WARNING

If the brake system warning light
 comes on together with the ABS
warning light
 stop the vehicle immediately and check the brake fluid level in
the reservoir page 167, “Brake fluid”. If the fluid level has dropped below the
MIN marking, do not drive any further - risk of accident! Obtain professional
assistance.

Pay attention to the following instruct ions before checking the brake fluid
level and opening the bonnet page 162, “Working in the engine compart-
ment”.

If the brake fluid is at the correct leve l, the ABS control function has failed.
The rear wheels may then block very rapi dly when braking. In certain circum-
stances, this can result in the rear end of the car breaking away - risk of skid-
ding! Drive carefully to the nearest specialist garage and have the fault
rectified.
Brake system

The warning light
 flashes or comes on if the brake fluid level is too low, if there is a
fault in the ABS or if the handbrake is applied.
If the warning light  flashes and an audible signal so unds three times (handbrake is
not applied), stop and check the brake fluid level .
The following text will be displayed in the information display*: Brake fluid Owner's manual
If there is a fault in the ABS which also infl uences the function of the brake system (e.g.
distribution of brake pressure), the ABS warning light
 comes on and at the same
time the brake system warn ing light starts flashing
. Be aware that not only the ABS
but also another part of th brake system is defective  .
An audible signal sounds three times as an additional warning signal.
One should get used to high pedal forces, an extended free play of the brake pedal and
long braking distances when carefully driving to the specialist garage.
For further information on the brake system page 135, “Brakes”.
Handbrake applied
The warning light
 also comes on if the handbrake is applied. An audible warning is
also given if you drive the vehicle for at least 3 seconds at a speed of more than 6 km/h.
The following text will be displayed in the information display*:
Release parking brake!

Have the airbag system checked immediat ely 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 124, “Deactivating airbags”.Diesel particle filter*

(diesel engine)
If the warning light

comes on, this means that soot has accumulated in the diesel
particle filter because of the frequent short distances.
In order to clean the diesel particle filter, the vehicle should be driven at an even speed
of at least 60 km/h at engine speeds of 1 800 - 2 500 rpm for at least 15 minutes or until
the warning light goes out with the 4th or 5th gear engaged (automatic gearbox: posi-
tion S) when the traffic situation permits it . This increases the exhaust temperature and
the soot deposited in the diesel particle filter is burnt.
Always pay attention to the valid speed limits .
The warning light

goes out after the successful cleaning of the diesel particle filter.
If the filter is not properly cleaned, the warning light

does not go out and the
warning light
 begins to flash. In the information display* appears Diesel-particle
Owner's manual . Afterwards the engine control unit shifts the engine into the emer-
gency 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.
