Asr System - Alfa Romeo 156 GTA Owner's Manual

ATTENZIONE
The turning on of the >
warning light (together
with the message + symbol shown
by the display) with the engine
running normally indicates an ABS
system fault. In this case the brak-
ing system preserves its effec-
tiveness, without however making
use of the antilock device. Under
these circumstances, the EBD sys-
tem may fail to give top perfor-
mance. In this case, too, you are
recommended to contact Alfa
Romeo Authorized Services imme-
diately, driving in such a way as to
avoid abrupt braking, to have the
system checked.

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).
WARNING
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.
