TC (Traction Control)
SYSTEM
The system automatically operates in
the event of slipping, loss of grip on wet
roads (aquaplaning) and acceleration on
slippery, snowy or icy roads, etc. on
one or more drive wheels. Depending
on the slipping conditions, two different
control systems are activated:
if the slipping involves both drive
wheels, the system intervenes, reducing
the power transmitted by the engine;
if the slipping only involves one of the
drive wheels, the BLD (Brake Limited
Differential) function is activated,
automatically braking the wheel which
is slipping (the behaviour of a
self-locking differential is simulated).
This will increase the engine torque
transferred to the wheel which isn't
slipping. This function remains active
even if the "Systems partially disabled"
and "Systems disabled" modes are
selected (see description in the
following pages).
System intervention
The intervention of the system is
indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the
vehicle is in critical stability and grip
conditions.
PBA (Panic Brake
Assist) SYSTEM
The PBA system is designed to improve
the vehicle’s braking capacity during
emergency braking.
The system detects emergency braking
by monitoring the speed and force with
which the brake pedal is pressed, and
consequently applies the optimal brake
pressure. This can reduce the braking
distance: the PBA system therefore
completes the ABS.
Maximum assistance from the PBA
system is obtained by pressing the
brake pedal very quickly. In addition, the
brake pedal should be pressed
continuously during braking, avoiding
intermittent presses, to get the most
out of the system. Do not reduce
pressure on the brake pedal until
braking is not necessary anymore.
The PBA system is deactivated when
the brake pedal is released.

HSA (Hill Start Assist)
SYSTEM
This is an integral part of the ESC
system and facilitates starting on
slopes, activating automatically in the
following cases:
uphill: vehicle stationary on a roadtransmission in neutral or gear other
than reverse engaged;
downhill: vehicle 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 the 2 seconds have elapsed,
without starting, the system is
automatically deactivated, gradually
releasing the braking pressure. During
this release stage, the typical
mechanical brake release noise can be
heard, indicating that the car is about to
move.

DST SYSTEM (Dynamic
Steering Torque)
The DST function uses the integration
of the ESC system with the electric
power steering to increase the safety
level of the whole vehicle.
