Pumping the anti-Lock brakes will
diminish their effectiveness and may
lead to a collision. Pumping brakes
makes the stopping distance longer.
Just press firmly on your brake pedal
when you need to slow down or stop.
Traction Control System (TCS)
This system is divided in PTC and BTCS
portions.
The current device is an integral
part of the ESC system. It operates
automatically by reducing the power
transmitted by the engine in case
of slipping, loss of grip on wet floor
(aquaplaning), acceleration on slippery
snow-covered or frozen surfaces, etc.
Activating under slip conditions different
control systems:
• if slippage affects both drive wheels, it
reduces the power transmitted by the
engine;
• if slippage only affects one drive
wheel, it brakes the slipping wheel
automatically.
Brake Assist System (BAS)
This system completes the ABS system
by optimizing the vehicle braking
capacity during emergency brake
manoeuvers. The system detects an
emergency braking situation by sensing
the rate and amount of brake application
and then applies optimum pressure
to the brakes to help reduce braking
distances.
The quick brake coupling is optimal for
BAS performances. To fully exploit the
system, apply continuous brake pedal
pressure during the entire vehicle stop
sequence. Do not reduce brake pedal
pressure earlier than required. Once
the brake pedal is released, the BAS is
deactivated.
Brake Throttle Override (BTO)
To complete the range of systems
that assist braking, the vehicle is
equipped with BTO, which is designed
to stop the vehicle even when it is
being accelerated. If the brake pedal is
depressed together with the accelerator,
the system does not consider as
"conflict" the sequence "brake-first-
then-accelerator" of pedal application
and it will not engage the BTO. When the
system recognizes that the accelerator
pedal is stuck pressed and the sequence
“accelerator-first then- brake-pressed”
(this sequence is recognized as a
“conflict”), the engine power will be
automatically reduced and, if the driver
continues to depress the accelerator, the
system can make the vehicle to come to
a complete stop.
Additionally, if the brake pedal is
released when the accelerator is still
stuck pressed, the corresponding engine
torque increase gradually to a safe value.
The system exits from this strategy
when the accelerator pedal is
completely unstuck.
Hill Start Assist (HSA)
The HSA system is designed to assist
the driver when starting a vehicle uphill.
HSA will maintain the level of brake
pressure applied for a short period of
time also after releasing the brake pedal.
If the driver does not apply the throttle
during this short period of time, the
system will release brake pressure
and the vehicle will start sloping
down. The system will release brake
pressure proportionally to the amount of
throttle/torque applied as the vehicle
starts to move in the chosen direction.
HSA Activation Criteria
The following criteria must be met in
order for HSA to activate:
• vehicle is stationary.
• gear selection matches vehicle uphill
direction (i.e., vehicle facing uphill is in
forward gear; vehicle backing uphill is
in reverse gear).
HSA will work in R (Reverse) and all
forward gears when the activation
criteria have been met.
