VDC AND ASR
SYSTEMS
(on request for versions/markets
where applicable)
When the sensors detect the conditions
that would lead to skidding, the VDC sys-
tem acts on the engine and brakes gener-
ating a stabilising torque.
VDC SYSTEM OPERATION
The VDC system turns on automatically
when the car is started and cannot be
switched off. It is however possible to cut
off operation of the ASR system pressing
the corresponding button on the centre
console.

The main components of the VDC sys-
tem are:

ver to run pointless and unjustified
risks. Driving conduct should al-
ways be suited to the conditions of

ty is always and anyway the ve-
hicle driver’s concern.
The VDC system helps the driver
to keep control of the car in the
event of loss of tyre grip.
The forces induced by the VDC sys-
tem to control the lack of stability
