SYSTEM INTERVENTION
This is indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the car is
in critical stability and grip conditions.
ABS
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 car
can be controlled even during
emergency braking and optimising
stopping distances.
The system intervenes when braking
and 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.
31) 32) 33) 34) 35) 36) 37)
System intervention
A slight pulsing of the brake pedal and
noise indicates the intervention of the
ABS: this is completely normal when
the system intervenes.
EBD SYSTEM
The EBD system is an integral part of
the ABS system and intervenes during
braking, distributing the brake force
optimally between front and rear
wheels.
This guarantees greater braking stability
for the vehicle, preventing sudden
locking of the rear wheels and
the consequent instability of the vehicle.
CBC (Cornering Brake
Control) SYSTEM
The system acts when braking on
corners, optimising the distribution of
brake pressure on the four wheels: the
system prevents the wheels on the
inside of the corner (less affected by the
weight of the car) from locking,
ensuring better stability and direction
for the car.DTC (Drag Torque
Control) SYSTEM
This is an integral part of the ABS
system and intervenes in the case of
sudden downshifting, or during braking
when the ABS intervenes, restoring
torque to the engine and thus
preventing excessive drag at the drive
wheels, which may lead the wheels
to lock and a loss of car stability, above
all in low-grip conditions.
ASR (AntiSlip
Regulation) SYSTEM
29) 30) 38) 39) 40)
This is an integral part of the ESC
system and automatically operates in
the event of one or both drive wheels
slipping, loss of grip on wet roads
(aquaplaning) and acceleration
on slippery, snowy or icy roads, etc.
Depending on the slipping conditions,
two different control systems are
activated:
❒if the slipping involves both drive
wheels, the ASR system intervenes,
reducing the power transmitted by
the engine;
❒if the slipping only involves one of the
drive wheels, it also intervenes
automatically, braking the wheel that
is slipping.
43

System intervention
This is indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the car is
in critical stability and grip conditions.
HILL HOLDER SYSTEM
This is an integral part of the ESC
system and facilitates starting on
slopes, activating automatically in the
following cases:
❒uphill: car 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: car 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 the 2 seconds have elapsed,
without starting, the system is
automatically deactivated, gradually
releasing the braking pressure. During
this release stage, the typical brake
disengagement noise, indicating that
the car is going to move imminently,
can be heard.
IMPORTANT The Hill Holder system is
not a parking brake; therefore, never
leave the vehicle without having
engaged the handbrake, turned the
engine off and engaged first gear,
so that the vehicle is parked in safe
conditions (for further information read
the "Parking" paragraph in the "Starting
and driving" chapter).
IMPORTANT There may be situations
on small gradients (less than 8%),
with vehicle laden, in which the Hill
Holder system may not activate,
causing a slight reversing motion and
increasing the risk of collision with
another vehicle or object. The driver is,
in any case, responsible for safe driving.HBA (Hydraulic Brake
Assistant) SYSTEM41) 42) 43)
The HBA system is designed to
improve the car’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 HBA system therefore
completes the ABS.
Maximum assistance from the HBA
system is obtained 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 HBA system is deactivated when
the brake pedal is released.

GETTING TO KNOW YOUR CAR

“ELECTRONIC Q2”
SYSTEM (“E-Q2”)
The "Electronic Q2" system intervenes
during acceleration on corners, braking
the inner drive wheel and thus
increasing the traction of the outer
wheel (which bears more of the car’s
weight): the torque is thus distributed
optimally between the drive wheels
in accordance with the driving
conditions and road surface, permitting
particularly effective, sporty driving.
"PRE-FILL" SYSTEM
(RAB - Ready Alert
Brake)
(only with “Dynamic” or "Race" mode
activated)
This function activates automatically if
the accelerator pedal is released
rapidly, reducing the brake pad travel
(both at front and back), with the aim of
preparing the braking system and
enhancing its responsiveness, thus
reducing the stopping distance in the
event of subsequent braking.
WARNING
26) The ESC can’t alter the natural
laws of physics, and can’t
increase grip, which depends on
the condition of the road.
27) The ESC system cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.
28) The capability of the ESC system
must never be tested irresponsibly
and dangerously, in such a way
as to compromise personal safety
and the safety of others.
29) For the correct operation of the
ASR system, the tyres must of
necessity be the same make and
type on all wheels, in perfect
condition and, above all, of the
prescribed type and dimensions. .
30) The performance of the ESC
and ASR systems must not
encourage the driver to take
unnecessary risks. Your driving
style must always be suited to the
road conditions, visibility and
traffic. The driver is, in any case,
responsible for safe driving.31) When the ABS intervenes and
you feel the brake pedal pulsating,
do not reduce the pressure, but
hold it down firmly and
confidently; in doing so you will
brake in the shortest distance
possible, depending on the
current road conditions.
32) For maximum efficiency of the
braking system, a bedding-in
period of about 500 km is
required: during this period it is
advisable to avoid sharp, repeated
and prolonged braking.
33) If the ABS intervenes, this
indicates that the grip of the tyres
on the road is nearing its limit:
you must slow down to a speed
compatible with the available grip.
34) The ABS can’t overrule the
natural laws of physics, and can’t
increase the grip available
according to the condition of the
road.
35) The ABS cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.
36) The capability of the ABS must
never be tested irresponsibly and
dangerously, in such a way as
to compromise personal safety
and the safety of others.

37) For the correct operation of the
ABS, the tyres must of necessity
be the same make and type on all
wheels, in perfect condition and,
above all, of the prescribed type
and dimensions.
38) The ASR system can’t overrule
the natural laws of physics, and
can’t increase the grip available
according to the condition of
the road.
39) The ASR system cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or

40) The capability of the ASR system
must never be tested irresponsibly
and dangerously, in such a way
as to compromise personal safety
and the safety of others.
41) The HBA system can’t overrule
the natural laws of physics, and
can’t increase the grip available
according to the condition of
the road.
42) The HBA system cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.43) The capability of the HBA system
must never be tested irresponsibly
and dangerously, in such a way
as to compromise the safety of
the driver, the other occupants of
the car or any other road user.“Alfa DNA” SYSTEM
(Dynamic car

“Race” MODE

ACOUSTIC SIGNAL
When reverse gear is engaged and
there is an obstacle behind the vehicle,
an acoustic signal is emitted which
varies according to the distance of the
bumper from the obstacle.
The frequency of the acoustic signal:
❒increases as the distance between
car and obstacle decreases,
culminating in a continuous acoustic
signal, when the distance is less
than approximately 30 cm;
❒decreases if the distance from the
obstacle increases, until the signal
ceases entirely;
❒remains constant if the distance
between car and obstacle remains
unchanged; if this situation concerns
the side sensors, the signal will
stop after approximately 3 seconds
to avoid, for example, indications
in the event of manoeuvres along a
wall.
If several obstacles are detected by the
sensors, only the nearest one is
considered.INDICATIONS ON
DISPLAY
(for versions/markets, where provided)
When the sensors are activated, the
screen in fig. 54 appears on the display.
Obstacle presence and distance
information is therefore provided both
by the acoustic signal and the
instrument panel display.
The system indicates a detected
obstacle by displaying an arc in one or
more positions according to the
distance of the obstacle and its position
in relation to the car.
If an obstacle is detected in the rear
central area, the display shows all the
arcs in the rear central area, up to
the one that corresponds to the
position of the obstacle itself.The signal is similar for obstacles in the
rear left or right area.
The arc that corresponds to the
position of the obstacle will flash.
The colour on the display depends on
the distance from and position of the
obstacle.
The car is close to the obstacle when
the display shows a single constant arc
and emits a continuous sound.
If there are several obstacles, the
closest one is indicated.
FAULT INDICATION
Parking sensor failures, if any, will be
indicated when reverse is engaged by
the switching on of the
warning
light on the instrument panel together
with the message on the display (see
“Warning lights and messages”
chapter).
GENERAL WARNINGS
45)

When parking, take the utmost care
over obstacles that may be above
or under the sensor.
