ESC (Electronic
Stability Control)
SYSTEM
IN BRIEF
The ESC system improves the
directional control and stability of the
vehicle 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 car.
26) 27) 28) 29) 30)
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
car’s understeer or oversteer.
❒Oversteer: occurs when the vehicle 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
The ESC system also includes the
following systems:
❒ABS
❒EBD
❒CBC
❒DTC
❒ASR
❒HILL HOLDER
❒HBA
❒“ELECTRONIC Q2” (“E-Q2”)
❒"PRE-FILL" (RAB - Ready Alert
Brake)
SYSTEM ACTIVATION
The ESC system activates automatically
when the engine is started and can
only be deactivated by selecting "Race"
mode. For more details, refer to the
"Alfa DNA system" paragraph in this
chapter.

GETTING TO KNOW YOUR CAR

Fiat Group Automobiles S.p.A.
authorises the installation of transceiver
devices on condition that such
installations are carried out in
a workmanlike fashion, following the
manufacturer’s instructions, at a
specialised centre.
IMPORTANT Traffic police may not
allow the car on the road if devices
have been installed which modify the
features of the car. This may also cause
invalidation of warranty in relation to
faults caused by the change either
directly or indirectly related to it.
Fiat Group Automobiles S.p.A. shall not
be liable for damage caused by the
installation of accessories either not
supplied or recommended by Fiat
Group Automobiles S.p.A. and/or not
installed in compliance with the
provided instructions.
RADIO TRANSMITTERS
AND MOBILE PHONES
Radio transmitter equipment (vehicle
mobile phones, CB radios, amateur
radio etc.) cannot be used inside the
car unless a separate aerial is mounted
on the roof.IMPORTANT The use of these devices
inside the passenger compartment
(without a separate aerial) may cause
the vehicle’s electronic systems to
malfunction. This could compromise
safety in addition to constituting a
potential hazard for passengers' health.
As far as the use of EC-approved
mobile phones is concerned (GSM,
GPRS, UMTS), follow the usage
instructions provided by the mobile
phone manufacturer.
WARNING
44) Take care when fitting additional
spoilers or non-standard alloy
wheels: they could reduce the
ventilation of the brakes and
affect efficiency in sharp,
repeated braking or on long
descents. Make sure that nothing
obstructs the pedal stroke (mats,
etc.).
PARKING SENSORS
(for versions/markets, where provided)
They are located in the rear bumper
fig. 53 and their function is to detect the
presence of any obstacles near the
rear part of the car; they consequently
inform the driver, through an
intermittent acoustic signal.
ACTIVATION/
DEACTIVATION
The sensors are automatically activated
when reverse gear is engaged. As the
obstacle behind the car gets closer, the
acoustic signal becomes more
frequent.
53A0L0043
51

Under certain circumstances, objects
close to the vehicle are not detected by
the system and could therefore cause
damage to the car or be damaged
themselves.
Some conditions may influence the
performance of the parking sensors:
❒the presence of ice, snow, mud
or multiple layers of paint on the
sensor surface may cause reduced
sensitivity of the sensor itself and
therefore reduce the system
performance;
❒mechanical interference (e.g. washing
the car, rain, strong wind, hail) may
cause the sensor to detect a
non-existent obstacle ("echo
interference");
❒the presence of ultrasonic systems
(e.g. pneumatic brake systems of
trucks or pneumatic drills) near the
car could alter the signals sent by the
sensor;
❒the variation in sensor position,
caused by variation in ride (due
to suspension component wear),
changing tyres, overloaded car,
or tuning that lowers the car, for
example, may affect parking sensor
system performance.
WARNING
45) The responsibility for parking
and other dangerous manoeuvres
always and in every case lies
with the driver. While carrying out
these manoeuvres, always make
sure that no people (especially
children) or animals are in the
area concerned. The parking
sensors are an aid for the driver,
but must never allow their
attention to lapse during
potentially dangerous
manoeuvres, even those executed
at low speeds.
IMPORTANT
4) The sensor must be free from
mud, dirt, snow or ice in order for
the system to operate correctly.
Be careful not to scratch or
damage the sensors while
cleaning them. Avoid using dry,
rough or hard cloths. The sensors
must be washed using clean
water, with the addition of car
shampoo if necessary. When
using special washing equipment
such as high pressure jets or
steam cleaning, clean the sensors
very quickly keeping the jet more
than 10 cm away. Also, do not
apply stickers to the sensors.

(SCHEDULED SERVICING)

Warning lights on
displayWhat it means What to do
GENERAL FAILURE
(for versions/markets, where provided)
The symbol lights up in the display in the
circumstances indicated below.
Engine oil pressure sensor failure
The symbol lights up when the engine oil pressure
sensor is faulty. The display shows the dedicated
message.In these case contact the dedicated Alfa Romeo
Dealership to have the fault fixed as soon as
possible.
"Clutch overheating" message
The
symbol, along with a message on the
display, lights up to indicate clutch overheating.
If the driver continues, the
symbol will switch
off and the
warning light will light up (on some
versions together with a message on the display)
to indicate a transmission failure.If the
symbol lights up along with a message
on the display, reduce gear shifting and/or
change usage conditions, until the normal
operating conditions are restored.
If the
warning light lights up (a message will
appear on the display, on some versions) stop
immediately, operate the handbrake, stop the
engine and wait 5 minutes: after this, normal
transmission operating conditions will be
restored.
Should the transmission failure condition persist,
contact the dedicated Alfa Romeo Dealership
FUEL CUT-OFF
The symbol and the corresponding message are
shown on the display in the following cases:
❒fuel cut-off system intervention: the yellow
symbol lights up;
❒fuel cut-off system failure: the red symbol lights
up.For the fuel cut-off system reactivation procedure,
refer to the "Fuel Cut-Off System" section of the
"Controls" paragraph, in the "Knowing your car"
chapter. If it is still not possible to restore the fuel
supply, contact the dedicated Alfa Romeo
Dealership.
