20)If, when the key is turned to MAR, the ¬warning light does not come on or if it stays on with the vehicle in motion (together with the
message on the display) there could be a failure in the safety systems; under these circumstances the airbags or pretensioners may not be
triggered in the event of an impact or, more rarely, they could be triggered accidentally. Before proceeding, contact a dedicated Alfa Romeo
Dealership to have the system checked immediately.
21)Failure of the
¬warning light is signalled by the flashing for longer than the usual 4 seconds of the “warning light. In addition, the airbag
system automatically disables the passenger side airbag. In this case, the ¬warning light may not indicate failures in the retaining systems.
Before proceeding, contact a dedicated Alfa Romeo Dealership to have the system checked immediately.
22)A failure of the
“warning light is indicated by the ¬warning light. In addition, the airbag system automatically disables the passenger
side airbag.
23)Deteriorated engine oil should be replaced as soon as possible after the digital warning light comes on, and never more than 500 km after it
first switches on. Failure to observe the above may result in severe damage to the engine and invalidate the warranty. Remember that when the
digital warning light comes on, it does not mean that the level of engine oil is low, so if it flashes you must not top up the engine oil.
24)If the warning light flashes with the car in motion, contact the dedicated Alfa Romeo Dealership.
IMPORTANT
3)If, when the ignition key is turned to MAR, the warning light does not turn on or if it turns on constantly or flashes when travelling

ACTIVE SAFETY SYSTEMS
ABS 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.
System intervention
The driver can feel that the ABS system
has come into action because the brake
pedal pulsates slightly and the system
gets noisier: this is entirely normal with
the system operating.
30) 31) 32) 33) 34) 35) 36)
ASR (AntiSlip Regulation) SYSTEM
37) 38) 39)
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.
System intervention
The system intervenes on the engine
power and the brakes.
It is indicated by the flashing of the
warning light on the instrument panel,
to inform the driver that the vehicle is
in critical stability and grip conditions.
HBA (Hydraulic Brake Assist) SYSTEM
40) 41) 42)
The HBA system is designed to improve
the car’s braking capacity during
emergency braking: the HBA system
therefore completes the ABS system.
Maximum assistance from the HBA
system is obtained by continuously
pressing the brake pedal very quickly.
EBD SYSTEM
The EBD system is an integral part of the
ESC system and intervenes during
braking, distributing the brake force
optimally between front and rear wheels.
This guarantees greater braking stability
for the car, preventing sudden locking of
the rear wheels and the consequent
instability of 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.

51
ESC 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.
25) 26) 27) 28) 29)
The ESC system comprises the active
safety systems such as: ABS, EBD, ASR,
HILL HOLDER, etc.
The ESC system switches on
automatically when the engine is started
and cannot be switched off.
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.
CBC
(Cornering Braking Control) SYSTEM
This 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.
HILL HOLDER SYSTEM
This is an integral part of the ESC system
and facilitates starting on uphill or
downhill slopes by operating the brakes:
IMPORTANT The Hill Holder system is
not a parking brake, therefore do not
leave the car without activating the
handbrake, switched the engine off and
engaged first gear, so that the car is
parked in safety conditions (for further
information read paragraph
“When parked” in the chapter “Starting
and driving”).
IMPORTANT There may be situations on
small gradients (less than 8%), with car
laden, in which the Hill Holder system
may not activate thus 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.
“ELECTRONIC Q2” SYSTEM (“E-Q2”)
The DTC system prevents the drive
wheels from possibly locking, which
could happen, for example, if the
accelerator pedal is released suddenly or
in the case of a sudden downshifting in
conditions of poor grip.
In this conditions, the engine braking
effect could cause the drive wheels to
slip, resulting in a loss of vehicle stability.
In these situations, the DTC system
intervenes, restoring torque to the
engine in order to conserve vehicle
stability and increase vehicle safety.

TPMS
(Tyre Pressure Monitoring
System)
(where provided)
DESCRIPTION
The tyre pressure monitoring system
(TPMS) warns the driver of low tyre
pressure on the basis of the cold
inflation pressure prescribed for the car.
Changes in outside temperature may
cause tyre pressure to vary.
This means that a decrease in the
outside temperature corresponds to a
decrease in the tyre pressure.
The tyre pressure must always be
adjusted according to the cold tyre
inflation pressure.
Cold tyre inflation pressure is the tyre
pressure after letting the car at a
standstill for at least three hours or a
travel shorter than 1.6 km after an
interval of three hours.
The cold tyre inflation pressure must not
exceed the maximum pressure indicated
on the tyre sidewall.Tyre pressure increases also while
driving: this is a normal condition and no
pressure adjustment is needed.
The TPMS continues to advise the driver
of the low tyre pressure condition until
this is corrected; the warning continues
until the pressure corresponds or
exceeds the pressure prescribed for the
cold tyres. When the low tyre pressure
warning light
nappears on the
instrument panel, the inflation pressure
must be adjusted up to the prescribed
cold inflation value.
The tyre pressure warning light switches
off after the system refreshes
automatically. You may need to drive the
car for about 20 minutes at a speed
higher than 20 km/h to allow the TPMS
to receive this information.
NOTE
❒ The TPMS does not replace the
normal tyre maintenance service and
does not indicate any fault in a tyre.
❒ The TPMS must not be used as a
pressure gauge while adjusting tyre
pressure❒ Driving with low tyre pressure causes
overheating and may cause a fault in the
tyres themselves. The low inflation
pressure reduces fuel efficiency and tyre
tread life and may also affect handling
and braking performance of the car.
❒ The TPMS does not replace the
correct tyre maintenance.
It is up to the driver to maintain the
correct tyre pressure level measuring it
with a suitable pressure switch. This is
necessary even if the decrease in the
inflation pressure value does not cause
the tyre pressure control warning light to
switch on.
❒ The TPMS warns the driver of any
condition of insufficient tyre pressure.
If this drops below the insufficient
pressure limit for any reason including
low temperature and normal pressure
loss of the tyre.
❒ The seasonal temperature changes
affect tyre pressure.

SAFETY
54 The TPMS uses wireless devices with
electronic sensors mounted on the wheel
rims to constantly monitor the value of
tyre pressure.

The sensors mounted on each wheel as
part of the valve stem transmit various
information of the tyres to the receiver
module, in order to calculate the
pressure.
IMPORTANT Monitoring and maintaining
the correct pressure in all four tyres are
particularly important.
Tyre pressure monitoring system
low pressure warnings
43) 44) 45) 46) 47) 48) 49) 50) 51)
The system warns the driver if one or
more tyres are flat by switching on the
nwarning light constantly and by
displaying a dedicated messages.
In this case, stop the car as soon as
possible, check the inflation pressure of
each tyre and inflate to the cold tyre
pressure value prescribed for the car.
The system will automatically update
and after receiving the pressure update
the tyre pressure warning light switches
off.
You may need to drive the car for about
20 minutes at a speed higher than 20
km/h to allow the system to receive this
information.

TPMS operation faults
The system fault is indicated by the
dedicated warning light
nwhich first
flashes for 75 seconds and then stays on
steadily. This can occur in any of the
following situations:
❒ Interference caused by electronic
devices or radio frequency emissions
similar to those of the TPMS sensors.
❒ Application of tinted films which
interfere with the signals of the radio
waves.
❒ Presence of snow or ice on the wheels
or the wheel arches.
❒ Use of snow chains.
❒ Use of wheels/tyres not equipped
with TPMS sensors.
