WARNING
31)If a failure is present with sharp braking, the rear wheels may lock and the vehicle may swerve.
Symbol What it means
GENERIC INDICATION
The symbol indicates information and failures.
The accompanying messages describe the failure.
FOUR WHEEL DRIVE FAILURE
This symbol switches on to report a four wheel drive system failure.
Contact an Alfa Romeo Dealership as soon as possible to have the failure eliminated.
TEMPORARY FOUR-WHEEL DRIVE FAILURE (where provided)
The symbol will appear to indicate that the AWD dynamic control system is temporarily deactivated to prevent damage because of
high engine load. The traction system will work in RWD mode in this case.
Until the symbol appears on the display, reduce the load to allow the system to cool down. The AWD system will resume normal
operation when the symbol disappears from the display.
DYNAMIC DRIVE CONTROL SYSTEM FAILURE
This symbol appears to indicate a traction system control failure.
AFS SYSTEM FAILURE
The symbol appears to indicate the automatic directional light system failure.
Go to an Alfa Romeo Dealership to have the system checked.

KNOWING THE INSTRUMENT PANEL

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.33) 34) 35) 36) 37) 38)
DTC (Drive Train Control)SYSTEM(where provided)
Some versions of this vehicle 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 car with
AWD automatically passes to rear-wheel
drive (RWD) when the road and
environmental conditions are such that
they would not cause the tyres to slip.When the road and environmental
conditions require better traction, the
vehicle automatically goes to AWD mode.
39)
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.
40)
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.
Oversteer: occurs when the car is

SAFETY

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.
41) 42) 43) 44) 45)
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.
46) 47) 48) 49) 50)
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.
51) 52) 53)
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.

WHEELS AND TYRES
171) 172) 173)
Before embarking on a long trip, and
every two weeks, check the tyre inflation
pressure. Check the tyres when cold.
SNOW CHAINS
81)
Rear Wheel Drive and All-wheel drive
versions
0.28 inch (7 mm) snow chains can be used
on all tyres. For tyres up to 8.86 in
(225 mm) in width (205/60R16,
225/55R16, 225/50R17, 225/45R18),
it is also possible to install 0.35 in (9 mm)
chains.
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 car
driveability, with the risk of losing control
of the car 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 (6200 /
9300 miles (10000 / 15000 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 tractionperformance on wet, muddy or snowy
roads, guaranteeing optimal driveability
of the vehicle.
In the case of irregular wear of the tyres
identify the cause and correct it as soon
as possible, by contacting an Alfa Romeo
Dealership.
All Wheel Drive (AWD) versions
It is recommended to avoid situations
with a large difference in wear between
the front and rear tyres and to strictly
use winter tyres of the sizes given in the
“Rims and tyres provided” table.
The AWD systems and the original tyres
were developed together to ensure the
vehicle’s best performance. When
changing the tyres, it is therefore
recommended to use the same “AR”
marked tyres, to maintain the same level
of performance and component life.
WARNING
171)The road holding qualities of the car
also depend on the correct inflation pressure
of the tyres.
172)If tyre pressure is too low, it may
overheat and be severely damaged as a
result.
173)Never submit alloy rims to repainting
treatments requiring the use of
temperatures exceeding 150°C. The
mechanical properties of the wheels could
be impaired.
