3)Before leaving the vehicle, ALWAYS
engage the handbrake. On versions
equipped with automatic transmission,
activate mode P (Park) and press the ignition
device to set it to STOP. When leaving the
vehicle, always lock all the doors by pressing
the button on the handle.
4)For versions equipped with the Keyless
Start system, do not leave the electronic key
inside or near the car or in a place accessible
to children. Do not leave the vehicle with the
ignition device in ON position. A child could
activate the electric window winders, other
controls or even start the vehicle.
5)If the ignition device has been tampered
with (e.g. an attempted theft), have it
checked over by the Alfa Romeo Dealership
before driving again.ENGINE IMMOBILIZER
The Engine Immobilizer system prevents
unauthorised use of the vehicle
preventing to start the engine.
The system does not need to be
enabled/activated: operation is
automatic, regardless of the fact that the
vehicle's doors are locked or unlocked.
When the ignition device is set to ON, the
Engine Immobilizer system identifies the
code transmitted by the key. If the code
is recognised as valid, the Engine
Immobilizer system enables engine
starting.
When the ignition device is brought back
to STOP, the Engine Immobilizer system
deactivates the control unit controlling
the engine, thus preventing its starting.
For the correct engine starting
procedures, see the instructions in the
"Starting the engine" paragraph,
"Starting and driving" chapter.Irregular operation
If, during starting, the key code is not
correctly recognised, theicon is
displayed on the instrument panel (see
the instructions in the "Warning lights and
messages" paragraph, "Knowing the
instrument panel" chapter). This
condition leads to the engine switching
off after 2 seconds. In this case, bring the
ignition device to STOP and then to ON; if
it is still blocked, try with the other keys
provided. If it is still not possible to start
the engine, contact an Alfa Romeo
Dealership.
If the
icon is displayed while driving,
this means that the system is running a
self-diagnosis (e.g. due to a voltage drop).
If the display persists, contact an Alfa
Romeo Dealership.

raise the bonnet completely: the
operation is facilitated by the presence
of two gas shock absorbers which hold it
the all open position.
Do not tamper with the shock absorber
and accompany the bonnet while lifting it.
CLOSING

WARNING LIGHTS ON INSTRUMENT PANEL
Possible detailed messages and/or acoustic signalling can be matched to a few warning lights and symbols.
Red warning lights
Warning
lightWhat it means
INSUFFICIENT BRAKE FLUID / ELECTRIC PARKING BRAKE ON
The warning light switches on when the ignition device is brought to ON, but it should switch off after a few seconds.
Low brake fluid level
The warning light turns on when the level of the brake fluid in the reservoir falls below the minimum level, possibly due to a leak in
the circuit.
Go to an Alfa Romeo Dealership to have the system checked as soon as possible.
Electric parking brake on
The warning light switches on when the electric parking brake is engaged.
Release the electric parking brake, then check that the warning light has switched off.
If the warning light stays on, contact an Alfa Romeo Dealership.
IMPORTANT If the car is parked on a gradient of more than 30% and/or the brake temperature is greater than 662°F (350°C),
when the parking brake is engaged, the warning light will flash to indicate a potentially unsafe condition.
EBD FAILURE
The simultaneous switching on of the
(red) and(amber) warning lights with the engine on indicates either a failure of the
EBD system or that the system is not available. In this case, the rear wheels may suddenly lock and the vehicle may swerve when
braking sharply.
Drive very carefully to the nearest Alfa Romeo Dealership to have the system inspected immediately.
48
KNOWING THE INSTRUMENT PANEL

Warning
lightWhat it means
AIRBAG FAILURE
The warning light switches on when the ignition device is brought to ON, but it should switch off after a few seconds. If the
warning light switches on constantly, this indicates a failure in the airbag system.
25) 26)
FRONT SEAT BELTS NOT FASTENED
The warning light switches on constantly if the vehicle is stationary and the driver side or passenger side seat belt, with the
passenger seated, is not fastened. The warning light flashes and a buzzer will sound if the vehicle is in motion and the driver side
or passenger side seat belt, with the passenger seated, is not correctly fastened.
EXCESSIVE ENGINE OIL TEMPERATURE
The warning light switches on in the case of engine oil overheating.
If the problem persists, contact an Alfa Romeo Dealership.
13)
WARNING
25)The fault of thewarning light is signalled by the switching on of theicon on the instrument panel. In this case, the warning light may not
indicate any faults with the restraint systems. Before proceeding, contact an Alfa Romeo Dealership to have the system checked immediately.
26)If the
warning light does not switch on when the ignition device is moved to ON or if it stays on when driving (together with the message on
the display), there might be a fault in the restraint systems; in this case, the airbags or pretensioners may not deploy in the event of an accident or,
in a lower number of cases, they could deploy erroneously. Before proceeding, contact an Alfa Romeo Dealership to have the system checked
immediately.
IMPORTANT
13)If the symbol switches on when driving, stop the vehicle and the engine immediately.
49

Warning
lightWhat it means
FUEL RESERVE / LIMITED RANGE
The warning light (or the icon on the display) switches on when there are about 1.8 UK gal (8 litres) of fuel left in the tank, for
diesel versions, and about 2.4 UK gal (9 litres) of fuel for petrol versions.
27)
INJECTION / EOBD SYSTEM FAILURE
In normal conditions, when the ignition device is brought to ON, the warning light switches on, but it should switch off as soon as
the engine is started.
The operation of the warning light may be checked by the traffic police using specific devices. Comply with the laws and
regulations of the country where you are driving.
14)
Injection system failure
If the warning light remains on, or it switches on whilst driving, the injection system is not working properly. The warning light on
constantly signals a malfunction in the supply/ignition system which could cause high exhaust emissions, a possible loss of
performance, poor driveability and high consumption.
The warning light switches off if the malfunction disappears, but is still stored by the system.
Under these conditions, the vehicle can continue travelling at moderate speed but without demanding excessive effort from the
engine or high speed. Prolonged use of the car with the warning light on constantly may cause damage. Contact an Alfa Romeo
Dealership as soon as possible.
Catalytic converter damaged
If the warning light flashes, it means that the catalytic converter may be damaged.
Release the accelerator pedal to lower the speed of the engine until the warning light stops flashing. Continue the journey at
moderate speed, trying to avoid driving conditions that may cause further flashing and contact an Alfa Romeo Dealership as soon
as possible.
WARNING

Symbol What it means
ENGINE COOLANT TEMPERATURE TOO HIGH
The symbol lights up when the engine has overheated.
In normal driving conditions: stop the car, switch off the engine and check that the coolant level in the reservoir is not below the
MIN mark. In this case, wait for the engine 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. Contact an Alfa Romeo
Dealership if the symbol comes on when the engine is started again.
If the vehicle is used under demanding conditions (e.g. in high-performance driving):slow down and, if the warning light stays on,
stop the vehicle. Stop for 2 or 3 minutes with the engine running and slightly accelerated to facilitate better coolant circulation,
then turn the engine off. Check that the coolant level is correct as described above.
DOOR OPEN
The symbol switches on when one or more doors are not completely shut. An acoustic signal is activated with the doors open and
the car moving.
Close the doors properly.
BONNET NOT PROPERLY SHUT
The symbol turns on when the bonnet is not properly closed, along with the icon, an image of the vehicle with an open bonnet
appears on the display.
A buzzer is heard when the bonnet is open and the vehicle is moving.
Close the bonnet properly.
BOOT NOT PROPERLY SHUT
The symbol turns on when the boot is not properly closed, along with the icon, an image of the vehicle with an open boot appears
on the display.
A buzzer is heard when the boot is open and the vehicle is moving.
Close the boot properly.
55

Symbol What it means
FUEL CUT-OFF SYSTEM OPERATION
The symbol switches on in the event of fuel cut-off system intervention.
For reactivating the fuel cut-off system, refer to the description in the "Fuel cut-off system" section in the "In an emergency"
chapter. If it is not possible to restore the fuel supply, contact an Alfa Romeo Dealership.
PARK SENSORS SYSTEM FAILURE
Lights up when the system has failed or is not available.
Contact an Alfa Romeo Dealership to have the system checked.
POSSIBLE ICE ON ROAD
The symbol turns on when the outside temperature falls to or below 37°F (3°C).
ENGINE OIL DETERIORATED
(where provided)
The symbol is displayed only for a limited time.
IMPORTANT After the first indication, each time the engine is started the symbol will continue to switch on as described above
until the oil is changed.
If the symbol flashes, this does not mean that there is a fault on the vehicle, rather it simply reports that it is now necessary to
change the oil as a result of regular use of the vehicle. The deterioration of engine oil is accelerated by using the vehicle for short
drives, preventing the engine from reaching operating temperature.
Contact an Alfa Romeo Dealership as soon as possible.
17)
IMPORTANT
17)Deteriorated engine oil should be replaced as soon as possible after the symbol is switched 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. When this symbol comes on, it
does not mean that the level of engine oil is low, so if it flashes you do not need to top up the engine oil.
Symbol What it means
GLOW PLUG PREHEATING (Diesel versions)
This warning light comes on when the ignition device is brought to ON and will switch off when the glow plugs have reached the
preset temperature. The engine can be started as soon as the warning light switches off.
IMPORTANT In mild or high temperature conditions, the warning light comes on for a very short time only.
57

Symbol What it means
SPEED LIMITER SYSTEM FAILURE
While driving, the symbol switches on to signal a Speed Limiter system failure.
Contact an Alfa Romeo Dealership as soon as possible to have the failure eliminated.
INSUFFICIENT ENGINE COOLANT LEVEL (where provided)
If the symbol switches on, it indicates a low engine coolant level condition.
Top up, as described in the "Servicing and Care" chapter
FUEL TANK CAP
(where provided)
Lights up if the fuel tank cap is open or not properly closed.
Tighten the cap properly.
ELECTRIC PARKING BRAKE FAILURE
The switching on of the symbol and the message on the display signal a failure in the electric parking brake system.
This failure may partially or completely block the car because the parking brake could remain activated even if automatically or
manually disengaged using the relevant controls. In these circumstances, you can disengage the parking brake following the
emergency disengagement procedure described in the "In an emergency" chapter.
If you are still able to drive the car (parking brake is not engaged), drive to the nearest Alfa Romeo Dealership and remember,
when executing any manoeuvres/commands, that the electric parking brake is not operational.
28)
ACTIVE CRUISE CONTROL SYSTEM FAILURE
While driving, if the warning light switches on it signals a failure in the Adaptive Cruise Control system.
Contact an Alfa Romeo Dealership to have the system checked.
WEAR ON BRAKE PADS
Lights up when the brake pads have reached their wear limit.
Contact an Alfa Romeo Dealership as soon as possible.
IMPORTANT Always use genuine parts or similar because the Integrated Brake System (IBS) system could detect anomalies.
WARNING
28)If a failure is present with sharp braking, the rear wheels may lock and the vehicle may swerve.
61

Symbol What it means
SOFT SUSPENSION CALIBRATION INSERTION (where provided)
Switches on when the most comfortable suspension setting is activated.
