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.
ASR (AntiSlip
Regulation) SYSTEM
It is an integral part of the ESC system.
It is automatically activated in the case
of 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.
Engagement/disengagement of the
ASR system
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. 47.
On some versions, the intervention of
the system is indicated by a dedicated
message shown on the display. When
the system is not active, the LED on the
button ASR OFF turns on and, on
some versions, a message appears on
the display.
When the ASR is deactivated whilst
driving, the next time the vehicle is
started the ASR is 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.

HBA (Hydraulic Brake
Assist) SYSTEM
The HBA system is designed to
improve the vehicle's braking capacity
during emergency braking. The system
detects an emergency braking by
monitoring the speed and strength with
which the brake pedal is pressed,
thereby applying the optimal brake
pressure.
This can reduce the braking distance:
the HBA system therefore completes
the ABS.
Maximum assistance from the HBA
system is obtained by pressing the
brake pedal very quickly. In addition,
the brake pedal must be pressed
continuously during braking, avoiding
intermittent presses, to benefit from the
system.
Do not reduce pressure on the brake
pedal until braking is not necessary
anymore.
The HBA system is deactivated when
the brake pedal is released.
