acceleration on slippery, snowy or icy
roads, etc. Depending on the slipping
conditions, two different control
systems are activated: if both drive
wheels skid, the ASR function
intervenes by reducing the power
transmitted by the engine while if only
one of the drive wheels skids, the
system intervenes by automatically
braking the wheel that is skidding.
Engagement/disengagement of the
ASR system
When setting off, the ESC system
control unit maintains the braking
pressure on the wheels until the torque
necessary for starting is reached, or
in any case for a maximum of 2
seconds, allowing your right foot to be
moved easily from the brake pedal to
the accelerator. If the vehicle has not
departed after this time, the system will
deactivate automatically by gradually
releasing the brake force. During this
release stage, the typical mechanical
brake release noise can be heard,
indicating that the vehicle is about to
move.
When the system is not active, the LED
on the same button turns on and, on
some versions, a dedicated message
appears on the display.
If the ASR is deactivated whilst driving,
the next time the engine is started
the ASR will be automatically activated.
When travelling on snowy roads with
snow chains, it may be helpful to turn
the ASR off: in fact, in these conditions,
the driving wheels skidding when
setting off gives you better traction.
The ASR system switches on
automatically each time the engine is
started. Whilst driving, the ASR can be
switched off and subsequently
switched on again by pressing the ASR
OFF button fig. 46.
WARNING
NOTE The Hill Holder system is not
active with parking brake engaged.
51) The ABS exploits the grip available to
the full, but it cannot improve it. Therefore,
you should take great care when driving
on slippery surfaces, without taking
unnecessary risks.
IMPORTANT The Hill Holder system is
not a parking brake, therefore do not
leave the vehicle without activating the
handbrake, switching off the engine,
and engaging first gear, with the vehicle
parked in safe conditions.
52) When the ABS intervenes and you
notice the brake pedal pulsating, do not be
afraid to keep the pedal pushed down.
This will help you to stop in the shortest
distance possible, depending on the road
conditions.
ASR (AntiSlip
Regulation) SYSTEM
53) If the ABS intervenes, it means you
have almost reached the grip limit between
the tyres and the road surface: slow down
to make sure you can use the available
grip.
