to cool down, then slowly and carefully open the cap, top
up with coolant and check that the level is between the
MIN and MAX marks on the reservoir itself. Also check
visually for any fluid leaks.
Should the warning light turn on again at the next
start-up, contact a dedicated Alfa Romeo Dealership.
If the car is used under demanding conditions
(e.g. in high-performance driving): slow down and, if the
warning light stays on, stop the car.
Wait for 2 or 3 minutes with the engine running and
slightly accelerated to further favour the coolant
circulation. Then stop the engine.
Check that the coolant level is correct as described
above.
IMPORTANT On particularly demanding journeys, it is
advisable to keep the engine on and slightly accelerated
for a few minutes before switching it off.

GENERIC FAILURE INDICATION
(where provided)
The symbol appears on the display together with the
events shown below.
Engine oil pressure sensor
The symbol appears when a failure is detected in the
engine oil pressure sensor. The display shows the
dedicated message.In this case, go to a dedicated
Alfa Romeo Dealership as soon as possible to have the
fault corrected.
Clutch overheating message
The
symbol, together with a message on the display,
lights up to indicate clutch overheating.
If you continue driving, the symbol
will disappear and
the warning light will come on (on some versions
together with a message on the display) to indicate a
gearbox fault.
If the symbol comes on together with a message on
the display, limit the gear shifting and/or change the
condition of use, until 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, switch off the engine and wait 5 minutes:
after this, normal transmission operating conditions will
be restored.

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
(on certain versions, together with the message on the display), contact a dedicated Alfa Romeo Dealership as soon as possible.

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.
