Tyre inflation pressure*
The warning light
lights up, if there is a substantial drop in inflation pressure in
one of the tyres. Reduce the speed and check or correct as soon as possible the inflation pressure in the tyres
⇒page 238.
If the warning light flashes, there is a system fault. Visit the nearest specialist garage and have the fault rectified. Further information about tyre pressure-control system
⇒page 199.
WARNING
•
When the warning light
lights up, immediately reduce the speed and
avoid sudden steering and brake mano
euvres. Please stop the vehicle
without delay at the nearest possible stop and inspect the tyres and their inflation pressures.•
Under certain circumstances (e.g. sporty style of driving, wintry or
unpaved roads) the warning light
can be delayed or does not light up at
all.
Note
If the battery has been disconnected, the warning light
comes on after switching
on the ignition. The warning light must
go out after driving a short distance.
Antilock brake system (ABS)
The warning light
shows the functionality of the ABS.
The warning light comes on for a few second
s 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 ig
nition, does not light up at all or lights
up while driving. The vehicle
will only be braked by th
e normal brake system. Visit
a specialist garage as quickly as possible and adjust your style of driving appropri-ately as you will not know how great the damage is. Further information about ABS
⇒page 197, “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 fault 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 231, “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 instru
ctions before checking the brake
fluid level and opening the bonnet
⇒page 225, “Working in the engine
compartment”.•
If the brake fluid is at the correct level, the ABS control function has
failed. The rear wheels may
then block very rapidly when braking. In certain
circumstances, this can result in the rear end of the car breaking away - risk of skidding! Drive carefully to the ne
arest specialist garage and have the
fault rectified.Bonnet
The warning light
comes on if the bonnet is unlocked. If the bonnet unlocks
while driving, the warning light lights up
and as a warning an audible signal
sounds.
