When switching the key to «
ON
», the ABS control unit performs a control of the sys-
tem, during which the ABS warning light flashes. This phase ends when exceeding 5
Km/h of speed with the switching off of the warning light.
In case of error of the system, the ABS warning light remains fixed. The braking system
keeps the characteristics of a traditional system.
In this case, reduce speed and go to an
Authorised Service Centre
for the appro-
priate checks.
WARNING
IF THE WARNING LIGHT IS FLASHING, THE ABS SYSTEM IS NOT ACTIVE.
System ASR (01_20, 01_21)
ASR SYSTEM
The ASR system is a driving aid that assists the driver in acceleration manoeuvres,
particularly on low-grip surfaces or under conditions that can cause sudden back-
wheel slippage. The ASR in these situations automatically intervenes by reducing
engine output within the limit imposed by the grip conditions, contributing significantly
to the maintenance of stability the vehicle.
WARNING
THE ASR SYSTEM IS BASED ON THE RECOGNITION OF SPEED DIFFERENCES
BETWEEN FRONT AND REAR WHEEL. IN ORDER FOR THE SYSTEM TO MAIN-
TAIN MAXIMUM EFFICIENCY IN ALL CONDITIONS, THE CALIBRATION PRO-
CEDURE MUST BE PERFORMED EVERY TIME, EVEN IN CASE OF REPLACE-
MENT OF JUST ONE TIRE.
