Operation
There is a fault in the ABS if:
●
The warning lamp
does not light up
when the ignition i
s switched on.
●
The control lamp does not go out again af-
ter a few seconds.
●
The control lamp lights up when the vehicle
is moving.
The vehicle can still be braked in the normal
way, without the ABS function. Take the vehi-
cle to a specialised workshop as soon as
possible. For further information on the ABS
see the ››› page 140.
If there is a fault in the ABS, the ESC* and the
tyre pressure control lamp will also light up.
Brake system fault
If the ABS warning lamp lights up together
with the brake warning lamp , there is a
fault in the ABS function and in the brake
system ›››
.
WARNING
●
Before opening the bonnet, read and ob-
serve the warnings ››› page 166, Working in
the engine compartment.
●
If the br
ake system warning lamp should
light up together with the ABS warning lamp
, stop the vehicle immediately and check
the brake fluid level in the reservoir
››› page 173, Brake fluid. If the brake fluid
level has dropped below the “MIN” mark you
must not drive on. Risk of accident. Obtain
technical assistance.
●
If the brake fluid level is correct, the fault in
the brake system may have been caused by a
failure of the ABS system. This could cause
the rear wheels to lock quickly when you
brake. This could cause the rear to break
away. Risk of skidding. Stop the vehicle and
seek technical assistance.
Differential lock fault (EDL)*
The EDL operates along with the ABS in vehi-
cles equipped with Electronic Stability Con-
trol (ESC)*.
A malfunction in the EDL is indicated by the
ABS control lamp . Take the vehicle to a
specialised workshop as soon as possible.
For further information on the EDL see
››› page 139, Electronic differential lock
(EDL)*
.
T
r
action control system (ASR)* /
The traction control system prevents the driv-
en wheels from spinning when the vehicle is
accelerating.
There are two warning lamps for the traction
control system: and . Both warning lamps
light up together when the ignition is switch-
ed on and should turn off after approximately
2 seconds. This is the time taken for the func-
tion check.
The
lamp has the following function:
●
It
flashes when the ASR is working if the ve-
hicle is moving.
If the system is deactivated or if it has any
fault, the warning lamp will remain lit. The
warning lamp will also light up if a fault
should occur in the ABS because the ASR op-
erates in conjunction with the ABS. For fur-
ther information, see ››› page 141.
The lamp provides information about the
disconnection status of the system:
●
It stays lit when the ASR is disconnected
when pressing the switch.
By pressing it again, the ASR function is reac-
tivated and the warning lamp switched off.
Electronic Stability Control (ESC)* /
There are two control lamps for the electronic
stability control. The lamp provides infor-
mation concerning function and disconnec-
tion status.
Both warning lamps light up together when
the ignition is switched on and should turn
