Panic Brake Assist (Pba) System; Hill Start Assist (Hsa) System - Alfa Romeo Stelvio 2019 User Manual

automatically braking the wheel which is
slipping (the behavior of a self-locking
differential is simulated). This will
increase the engine torque transferred to
the wheel which isn't slipping.
System Intervention
The intervention of the system is
indicated by the flashing of the ESC
warning light on the instrument panel, to
inform the driver that the vehicle
stability and grip are critical.

Panic Brake Assist (PBA) 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
complements 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 no longer
necessary.
80
The PBA system is deactivated when the
brake pedal is released.
Warning!
The Panic Brake Assist (PBA) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road
conditions. PBA cannot prevent collisions,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities
of a PBA-equipped vehicle must never be
exploited in a reckless or dangerous
manner, which could jeopardize the user's
safety or the safety of others.

Hill Start Assist (HSA) System

This is an integral part of the ESC system
that facilitates starting on slopes,
activating automatically in the following
cases:
Uphill: the vehicle is stationary on a
road with a gradient higher than 5%, the
engine is running, the brake is pressed,
and the transmission is in NEUTRAL (N)
or a gear other than REVERSE (R) is
engaged.
Downhill: the vehicle is stationary on a
road with a gradient higher than 5%, the
engine is running, the brake is pressed,
and the transmission is in REVERSE (R).
When starting from a stop, 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 two
seconds, allowing your right foot to be
moved easily from the brake pedal to the
accelerator.
The system will automatically deactivate
after two seconds without starting,
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 vehicle.
Warning!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight
rolling may occur, such as on minor hills or
with a loaded vehicle, or while pulling a
trailer. HSA is not a substitute for active
driving involvement. It is always the driver's
responsibility to be attentive to distance to
other vehicles, people, and objects, and
most importantly brake operation to ensure
safe operation of the vehicle under all road
conditions. Your complete attention is
always required while driving to maintain
safe control of your vehicle. Failure to
follow these warnings can result in a
collision or serious personal injury.
