Asr System - Alfa Romeo 147 Owner's Manual

ASR SYSTEM

(Antislip Regulation)
(upon request for
versions/markets where
applicable)
The ASR function controls the car drive 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.
144
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).
WARNING
The performance of the
system in terms of active
safety should not induce the driver
to take pointle e ss and unnecessary
risks. The style of driving must in
any case be adapted to the condi-
tions of th h e road surface, visibili-
ty and traffic. Road surface is al-
w a y s t h e d r i v e r 's responsibility.
