ASR SYSTEM (AntiSlip Regulation)
It is an integral part of the ESC system. It
automatically operates 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…
Depending on the slipping conditions, two different
control systems are activated:
❒if the slipping involves both drive wheels, the ASR
intervenes reducing the power transmitted by the
engine;
❒if the slipping only involves one of the drive
wheels, it intervenes automatically braking the
wheel that is slipping.
Activation/deactivation of the ASR system
The ASR system activates automatically each time
the engine is started.
Whilst driving, the ASR can be deactivated and
subsequently activated again by pressing the ASR
OFF button fig. 109.
On some versions, the intervention of the system is
indicated by a message shown on the display.
When the system is deactivated, the LED on the
button ASR OFF turns on and, on some versions, a
message appears on the display.
If the ASR is disengaged during driving, this is
automatically reactivated at the following car starting.
When travelling on snowy roads with snow chains,
it may be helpful to turn the ASR off: in fact, in these
conditions, slipping of the drive wheels when moving
off makes it possible to obtain better traction.
WARNING
For the ESC and ASR systems to operate
correctly, all four tyres must , above all,
be the prescribed brand and type, they must be
in excellent condition and feature the
prescribed type and size.
WARNING
The ESC functions even when the
space-saver wheel is being used. Always
remember that the space-saver wheel, being
smaller than the original wheel, provides less
grip.
