In general, the ESP should be left switched on at all times. In particular cir-
cumstances where a certain amount of wheel slip is desirable, it may be ad-
visable to switch off the ESP. Examples:
●
when driving with snow chains
●
when driving in deep snow or on loose surfaces
●
when rocking the vehicle backwards and forwards to free it.
The ESP should be switched on again afterwards as soon as possible.
WARNING
The ESP is not able to overcome the physical limits of adhesion. Even
with ESP, you should always adjust your speed to suit the conditions.
Please bear this in mind, especially on wet or slippery road surfaces. Do
not let the extra safety features tempt you into taking any risks when
driving. Failure to do so could result in an accident.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking.
The anti-lock brake system (ABS) is an important part of the vehicle's active
safety system. However, the ABS will not necessarily guarantee shorter
stopping distances in all conditions. For instance, on loose gravel or fresh
snow on top of an icy surface (conditions which anyway require extreme
care and reduced speed), the stopping distance with ABS may even be
slightly longer.
How the ABS works
The system runs an automatic self-check when the vehicle reaches a road
speed of about 6 km/h. This may be accompanied by a noise from the ABS
pump.
When one of the wheels is turning very slowly in relation to the road speed
and is close to locking up, the system will reduce the brake pressure on that
wheel. The driver is made aware of this adjustment process by a
vibration of
the brake pedal
and an audible noise. This is a deliberate warning to the
driver that one or more of the wheels is tending to lock up and the ABS con-
trol function has intervened. In this situation it is important to keep the
brake pedal fully depressed so the ABS can regulate the brake application,
but do not “pump” the brake pedal.
WARNING
The grip provided by ABS is still subject to the physical limits of adhe-
sion. Always bear this in mind, especially on wet or slippery roads. If you
notice that the ABS is working (to counteract locked wheels under brak-
ing), you should reduce speed immediately to suit the road and traffic
conditions. Do not let the extra safety features tempt you into taking any
risks when driving. Failure to do so could result in an accident.
Note
If a malfunction should occur in the ABS, this is indicated by a warning lamp
