In vehicles with 4-wheel drive, the TCS is dis-
connected completely . In addition, the con-
trol lamp lights up on the instrument cluster.
WARNING
The ESC Sport mode should only be switched
on if the trac situation and the driver’s abil-
ity allow it. Danger of skidding!
●
With ESC in Sport mode, the stabilising
function will be limited for sportier driving.
The vehicle may skid.
Note
If the TCS is disconnected or “Sport” mode is
selected, cruise control will be switched o.
Troubleshooting
The electromechanical brake servo is
not working
Stop driving
The warning lamp lights up red.
A message is displayed as appropriate. De-
press the brake pedal hard because the brak-
ing distance will increase due to the lack of
brake assist from the brake servo.
●
You should obtain professional assistance im-
mediately.
There is a fault in the electromechani-
cal brake servo
The control lamp switches on yellow.
A message is displayed for a few seconds.
Depressing the brake pedal may cause vibra-
tions. The brake pedal has to be pressed harder
because the braking distance increases due to
the reduced brake servo assistance.
●
Contact a specialised workshop.
The ABS does not work properly or does
not work at all
The control lamp switches on yellow.
●
Contact a specialised workshop. The vehi-
cle’s brakes still work without the ABS.
The ESC or TCS is regulating
The control lamp flashes yellow.
ESC fault
The control lamp switches on yellow. The ESC
has been switched o.
There is a fault or defect.
●
Turn o the ignition and turn it on again.
●
If possible, drive for a short distance at 15-20
km/h (9-12 mph).
●
If the control lamp is still on, go to a speci-
alised workshop.
The brake assist systems make noises
When the described brake assist systems inter-
vene, you may hear noises.
WARNING
●
When the ignition is switched on, the sta-
tus of the brake system and the brake assist
functions are automatically checked. The
control lamps on the instrument cluster light
up briefly and then go out. Any indicator
lamp that remains on indicates a fault. Seek
qualified technical assistance immediately.
●
If the brake system warning light comes
on together with the control lamp, the ABS
regulation function may not work and the
rear wheels may lock relatively quickly when
braking. This can lead to loss of control of
the vehicle! If possible, slow down and drive
slowly and carefully to the nearest specialist
workshop to have the brake system inspec-
ted. During this journey, avoid heavy braking
and any sudden manoeuvres.
●
If the indicator lamp does not go out, or
comes on while driving, it means that the ABS
function cannot work properly, is not availa-
ble and will not work during braking. Go to a
specialised workshop as soon as possible.
