Instruments and warning lights
32
Note
If the battery has been disconnected
and reconnected, 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 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 immediately and adjust your
style of driving appropriately as you will
not know how grea
t the damage is.
Further information about ABS
page 140, “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 171, “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 166, “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 sp
ecialist 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 warning 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 139, “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!WARNING (continued)

– Change the damaged wheel or consult a specialist garage about possibilities for
getting repairs done.
WARNING
It is necessary to observe the guidelines given on
page 180, “New tyres and
wheels” if the vehicle is subsequently fi
tted with tyres which are different to
those it was fitted with at the works.
Note
If you find, when changing the wheel, that
the wheel bolts are corroded and diffi-
cult to turn, the bolts must be replaced
before checking the tightening torque.
Drive cautiously and only at a moderate speed to a workshop where the tightening
torque can be checked.Full wheel trim*Pulling off– Hook the clamp found in the vehicle tool
kit into the reinforced edge of the full
wheel trim.
– Push the wheel key through the clamp, support the wheel key on the tyre and pull
off the wheel trim
fig. 152
.
Installing– First press the full wheel trim onto the wheel at the valve opening provided. Then
press the full wheel trim into the wheel in
such a way that its entire circumference
locks correctly in place.Caution
Use the pressure of your hand, do not knock on the full wheel trim! Heavy knocks
mainly on the points where the full wheel trim has not been inserted into the wheel, can result in damage to the guide and centering elements of the full wheel trim.
Check for yourself that the safety wheel bolt
is located in the hole in the area of the
valve before fitting the full wheel trim onto a
steel wheel which is attached with a safety
wheel bolt
page 190, “Securing wheels against being stolen*”.
Wheel bolts with caps* The caps are designed to protect the wheel bolts.Pulling off– Insert the
plastic clip
(in the car tool kit) sufficiently
far onto the cap until the inner
catches of the clip are positioned at the collar of the cap.
– Pull the cap off with the
plastic clip
fig. 153
.
Installing– Insert the caps onto the bolts.
