WARNING
●
If the ABS warning lamp does not go
out or if it lights up whil
e driving, the ABS is
not working properly. The vehicle can only
be stopped using normal braking without
ABS. The protection provided by the ABS is
not available. Visit a specialised workshop
as soon as possible.
Brake assist systems
The brake assistance systems ESC, ABS, BAS,
ASR and EDL only operate when the ignition is
s
witched on. They contribute significantly to
increasing active safety.
Electronic Stability Control (ESC)
ESC reduces the risk of skidding and increa-
ses the vehicle stability by braking individual
wheels under specific driving conditions. ESC
detects critical handling situations, such as
understeer, oversteer and wheelspin on the
driving wheels. The system stabilises the vehi-
cle by braking individual wheels or by reduc-
ing the engine torque.
ESC has its limits. It is important to realise that
ESC is also subject to the laws of physics.
ESC will not be able to deal with all situations
with which drivers may be faced. For exam-
ple, if the road surface changes suddenly
then ESC will not be useful in all cases. If the
vehicle suddenly enters a section covered by
water, mud or snow then ESC will not provide
assistance in the same way as on dry ground.
If the vehicle loses its grip on the ground and
moves on a film of water (“aquaplaning”), the
ESC will not be able to help the driver control
the vehicle due to the loss of adherence with
the road surface, which prevents braking and
steering. If the vehicle is driven through series
of bends at high speed, the ESC will not al-
ways be as effective: aggressive driving is not
the same as slow driving. When driving with a
trailer
, ESC does not provide the same
amount of vehicle control as without a trailer.
Adjust your speed and driving style to road,
traffic and weather conditions. ESC cannot
push the limits of the laws of physics; improve
the transmission available or maintain the ve-
hicle on the road if a lack of driver attention
creates an inevitable situation. Otherwise,
ESC assists in maintaining vehicle control in
extreme situations and uses the movements
of the steering made by the driver to maintain
the vehicle moving in the desired direction. If
the vehicle is driven at such a speed that it
will leave the road before ESC can intervene
then the system cannot provide assistance.
The ABS, BAS, ASR and EDL systems are in-
corporated into ESC. ESC is always on. The
ESC should only be turned off using the ASR
button

Fig. 240 when traction is insuffi-
cient. Always remember to turn on the ASR
once more when the vehicle has traction
again.
Anti-lock system (ABS)
ABS can prevent the wheels from locking dur-
ing braking until just before the vehicle stops
thus helping the driver to steer the vehicle
and maintain control. This means that, even
during full braking, the risk of skidding is re-
duced:
