Active Safety Systems - Alfa Romeo Giulia Owner's Handbook Manual

ACTIVE SAFETY SYSTEMS

The vehicle may be equipped with the
following active safety devices:
ABS (Anti-Lock Brakes);
DTC (Drive Train Control);
ESC (Electronic Stability Control);
TC (Traction Control);
PBA (Panic Brake Assist);
HSA (Hill Start Assist);
AST (Alfa™ Steering Torque);
ATV (Alfa™ Active Torque Vectoring).
For the operation of the systems, see the
following pages.
ABS (Anti-lock Braking System)
This system, which is an integral part
of the braking system, prevents one
or more wheels from locking and
slipping in all road surface conditions,
irrespective of the intensity of the
braking action, ensuring that the vehicle
can be controlled even during emergency
braking and optimising stopping
distances.
The system intervenes during braking
when the wheels are about to lock,
typically in emergency braking or
low-grip conditions, when locking may be
more frequent.
The system also improves control and
stability of the car when braking on a
surface where the grip of the left and
right wheels varies, or on corners.

The Electronic Braking Force
Distribution (EBD) system completes the
system allowing the brake force to be
distributed between the front and rear
wheels.
System intervention
The ABS equipped on this vehicle is
provided with the "Brake by wire"
(Integrated Brake System - IBS) function.
With this system, the brake pedal
command given by pressing the brake
pedal is not transmitted hydraulically
but electronically, therefore, the light
pulsation that could be felt on the pedal
with the traditional system is no longer
perceptible.

DTC (Drive Train Control) SYSTEM
(where provided)
Some versions of this car are
equipped with an automatically
activated/deactivated four-wheel drive
system (AWD), which offers an optimal
drive for countless driving conditions
and road surfaces. The system reduces
the slipping of the tyres to a minimum,
automatically redistributing the torque
to the front and rear wheels, as needed.
To maximize fuel savings, the vehicle
with AWD automatically passes to rear
four-wheel drive (RWD) when the road
and environmental conditions are such
that they wouldn't cause the tyres to slip.
When the road and environmental
conditions require better traction, the
vehicle automatically goes to AWD
mode.

WARNING If the system failure symbol
switches on, after starting the engine
or while driving, it means that the AWD
system is not working properly. If the
warning message activates frequently,
it is recommended to carry out the
maintenance operations.
43)
ESC (Electronic Stability Control)
SYSTEM
The ESC system improves the directional
control and stability of the car in various
driving conditions.
The ESC system corrects the car's
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by the
engine can also be reduced in order to
maintain control of the vehicle.
The ESC system uses sensors installed
on the car to determine the trajectory
that the driver intends to follow and
compares it with the car's effective
trajectory. When the real trajectory
deviates from the desired trajectory, the
ESC system intervenes to counter the
vehicle's understeer or oversteer.
