ASR SYSTEM
(Antislip Regulation)
(upon request for
versions/markets where
provided)
The ASR function controls the vehicle dri-
ve and cuts in automatically every time one
or both driving wheels slip.
In slipping conditions, tow different control
systems are activated:
1) if slipping involves both driving wheels,
being caused by excessive power transmit-
ted, the ASR device cuts in reducing the pow-
er transmitted by the engine.
2) if slipping involves only one driving
wheel, the ASR system cuts in automatical-
ly braking the wheel that is slipping, with
an effect similar to that of a self-locking dif-
ferential.
154
The action of the ASR is particularly help-
ful in the following circumstances:
– slipping of the inner wheel on a bend,
due to the effect of dynamic load changes
or excessive 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).
The performance of the
system in terms of active
safety should not induce
the driver to take pointless and un-
necessary risks. The style of dri-
ving must in any case be adapted
to the conditions of the road sur-
face, visibility and traffic. Road
surface is always the driver's re-
sponsibility.
SWITCHING ON
THE ASR FUNCTION
The ASR function switches on automati-
cally each time the engine is started.
When travelling the device can be switched
off and on again pressing switch (A-
fig. 153) on the centre console.
When the device is switched off this is
shown by the lighting up of the led on the
switch itself.
If the function is switched off when trav-
elling, it will turn on again automatically the
next time the engine is started.
