traction control Alfa Romeo Giulia 2016 Owner's Manual

ACTIVE SAFETYSYSTEMS
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 vehicle 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 vehicle are
equipped with a four-wheel drive system
(AWD), activated on request, 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 environmentalconditions require better traction, the
vehicle automatically goes to AWD mode.
36)
The driving mode, RWD or AWD, is shown
on the instrument panel display.
IMPORTANT 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.
37)
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.
66
SAFETY

Oversteer: occurs when the car is
turning more than it should according to
the angle of the steering wheel.
Understeer: occurs when the vehicle is
turning less than it should according to
the angle of the steering wheel.
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.
38) 39) 40) 41) 42)
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 both 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.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.
43) 44) 45) 46) 47)
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
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.
The PBA system is deactivated when the
brake pedal is released.
48) 49) 50)
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 road
with a gradient higher than 5%, engine
running, brake pressed and transmission
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 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.

LIFTING THE VEHICLE
If the car needs to be jacked up, go to an
Alfa Romeo Dealership which is equipped
with shop jacks or jack arms.
The vehicle lifting points are marked on
the side skirts with the
symbols (see
illustration in fig. 153 ).
WHEELS AND TYRES
157) 158) 159)
SNOW CHAINS
70)
Rear Wheel Drive and All-wheel drive
versions
0.28 in (7-mm) snow chains can be used
on all tyres. For tyres up to 8.8
Ûin
(225 mm) in width (205/60R16,
225/55R16, 225/50R17, 225/45R18),
it is also possible to install 0.35 in (9 mm)
chains.
We recommend using snow chains
available from the Alfa Romeo
Dealership.
Important notes
The use of snow chains should be in
compliance with local regulations of each
country. In certain countries, tyres
marked with code M+S (Mud and Snow)
are considered as winter equipment;
therefore their use is equivalent to that
of the snow chains.
The snow chains may be applied only to
the rear wheel tyres.
Check the tension of the snow chains
after the first few metres have been
driven.
IMPORTANT Using snow chains with
tyres with non-original dimensions may
damage the vehicle.
IMPORTANT Using different size or type
(M+S, snow, etc.) tyres between front and
rear axle may adversely affect vehicle
driveability, with the risk of losing control
of the vehicle and resulting accidents.
SUGGESTIONS ABOUT THE ROTATION
OF THE TYRES
The front and rear tyres are subject to
different loads and stress due to
steering, manoeuvres and braking. For
this reason they are subject to uneven
wear.
To resolve this problem, tyres should be
rotated at the appropriate time
(3,000/6,000 mi - 5,000/10,000 km).
Inverting the tyres means moving them
to different positions on the same side of
the car (front to back and vice versa).
IMPORTANT Crossing the tyres is not
advised, so placing a tyre on a different
axle on the other side of the car is
impossible.
IMPORTANT On cars equipped with
differentiated tyres (tyre size different
between front and rear axles, ex. QV
version) rotation of any of the tyres is not
advised.
Tyre rotation contributes to the
preservation of the grip and traction
