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. 136
) on the centre console.
Function disconnection is shown by the rel-
evant led on the switch itself being turned
on and by the dedicated message displayed
on the re-configurable multifunction display.
Should the function be disconnected when
running, it will automatically be activated
again at the next ignition and the re-con-
figurable multifunction display will inform
user about this condition by displaying a ded-
icated message.

ASR SYSTEM
(
Antislip Regulation
)
The ASR function controls the vehicle dri-
ve and cuts in automatically every time one
or both driving wheels slip.
In slipping conditions, two 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.
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 unnecessary
risks. The style of driving must in
any case be adapted to the condi-
tions of the road surface, visibili-
ty and traffic. Road safety is al-
ways the driver’s responsibility.
