ASR SYSTEM
(AntiSlip Regulator)
(where provided)
The ASR function controls car drive and
cuts in automatically every time one or
both driving wheels slip.
According to slipping conditions, two dif-
ferent control systems are activated:
❒ if slipping involves both driving wheels,
the ASR function intervenes reducing
the power transmitted by the engine;
❒ if slipping involves only one driving
wheel, the TC (Traction Control)
function cuts in automatically braking
the wheel that is slipping.
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 condi-
tions 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 THE ASR SYSTEM
ON/OFF fig. 125
The ASR system switches on
automatically each time the engine is
started.
When travelling ASR can be switched off
and on again pressing switch A set aside
the gearshift lever.
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.
During the use of the space-
saver spare wheel, the ESP
system carries on working. However,
you must remind that the space-saver
spare wheel has dimensions smaller
than the standard tyre and therefore
its grip is reduced as to the other car
tyres.
WARNING
For correct operation of the
ESP system, the tyres must
absolutely be of the same brand and
type on all wheels, in perfect condi-
tions and, above all, of type, brand
and size specified.
