ASR SYSTEM
(Antislip Regulation)
It is an integral part of the ESP system, it
controls car drive and cuts in automati-
cally every time one or both driving
wheels slip.
According to slipping conditions, two dif-
ferent control systems are activated:
❒ if the slipping involves both the driving
wheels, the ASR function intervenes re-
ducing the power transmitted by the
engine;
❒ if the slipping involves only one driving
wheel, the ASR system cuts in auto-
matically braking the wheel that is slip-
ping.
The action of the ASR is particularly help-
ful in the following circumstances:
❒ slipping of the inner wheel due to the
effect of dynamic load changes or ex-
cessive acceleration;
❒ too much power transmitted to the
wheels also in relation to the conditions
of the road surface;
❒ acceleration on slippery, snowy or
frozen surfaces;
❒ in the case of loss of grip on a wet sur-
face (aquaplaning).
Switching on/off of the ASR system
The ASR system switches on automatically
each time the engine is started.
Switching on/off is indicated by the rele-
vant message on the display (see section
“Warning lights and messages”).
When travelling ASR can be switched off
and on again pressing switch A-fig. 123
on the central console.
When the ASR is switched off this is
shown by the lighting up of the led on the
switch and by the relevant message on the
display (see section “Warning lights and
messages”).
If the ASR is switched off when travelling,
it will turn on again automatically the next
time the engine is started.
When travelling on snowy roads with
snow chains, it may be helpful to turn the
ASR off: in fact, in these conditions, slip-
ping of the driving wheels when moving off
makes it possible to obtain better drive.
The performance of the sys-
tem, in terms of active safe-
ty should not induce the driver to take
pointless and unnecessary risks. The
style of driving must in any case al-
ways be adapted to the conditions of
the road surface, visibility an traffic.
Road safety is always the driver’s re-
sponsibility.
