ASR SYSTEM (AntiSlip Regulation)
This is an integral part of the VDC system. It automatically cuts in
in the event of one or both drive wheels slipping, loss of grip on
wet roads (aquaplaning) and acceleration on slippery, snowy or icy
roads etc.
According to slipping conditions, two different control systems are
activated:
❍ if slipping involves both drive wheels, the ASR function inter-
venes by reducing the power transmitted by the engine;
❍ if the slipping involves only one drive wheel, the ASR system
intervenes by automatically braking the wheel that is slipping.
If the spare wheel is in use the ASR system does
not work. in this case the á warning light will come
on in the instrument panel.
In order for the ESP and ASR systems to operate
correctly, it is essential that the tyres are of the
same brand and type on all wheels, in perfect con-
dition and, above all, of the specified type, brand and size.
GETTING TO KNOW YOUR CAR
If the spare wheel is used, the VDC system keeps
operating. Be aware however that the spare wheel,
being smaller than the original wheel, provides less
grip.
The performance of the VDC and ASR systems
should not encourage the driver to take unneces-
sary risks. Your driving style should always take
road conditions, visibility and traffic into account. The dri-
ver is ultimately responsible for road safety.
