HH (Hill Holder) SYSTEM
This is an integral part of the ESC
system and facilitates starting on
slopes, activating automatically in the
following cases:
uphill: car stationary on a road with a
gradient higher than 5%, engine
running, brake pressed and gearbox in
neutral or gear (other than reverse)
engaged;
downhill: car stationary on a road
with a gradient higher than 5%, engine
running, brake pressed and reverse
gear engaged.
When setting off, the ESC system
control unit maintains the braking
pressure on the wheels until the engine
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.
When two seconds have elapsed,
without starting, the system is
automatically deactivated, gradually
releasing the braking pressure.
During this release stage it is possible
to hear a typical mechanical brake
release noise, indicating the imminent
movement of the car.

ASR (AntiSlip
Regulation) SYSTEM
This is an integral part of the ESC
system and 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 system intervenes,
reducing the power transmitted by the
engine;
if the slipping only involves one of
the drive wheels, it also intervenes
automatically, braking the wheel that is
slipping.
System intervention
This is indicated by the lighting of the
warning light
on the instrument
panel, to inform the driver that the car is
in critical stability and grip conditions.
Manual engagement/
disengagement
The ASR comes on automatically
whenever the engine is started. Whilst
driving, the ASR can be switched off
and subsequently switched on again by
pressing button 1fig. 49 (TTC). When
the system is not active, the LED on the
same button 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,
the driving wheels skidding when
moving off gives you better traction.

PBA (Panic Brake
Assist) SYSTEM
The PBA 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 PBA system
therefore completes the ABS.
