Warning lights on
panelWhat it means What to do
EBD FAILURE
The simultaneous switching on of the
(red) and
(amber) warning lights with the engine on indicates
either an anomaly 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.
AIRBAG FAILURE
The warning light switches on when the ignition key is
turned to MAR, but it should switch off after a few seconds.
If the warning light switches on constantly, this indicates a
fault in the airbag system.
22) 23)
SEAT BELTS NOT FASTENED
(for versions/markets, where provided)
The warning light switches on constantly with the vehicle
stationary and the driver’s seat belt not fastened.
The warning light flashes and a buzzer sounds if the car is in
motion and the front seat belts are not correctly fastened.For permanent deactivation of the acoustic signal (buzzer)
of the S.B.R. (Seat Belt Reminder) system contact an Alfa
Romeo Dealership. The system can be reactivated using
the Setup Menu.

Warning lights on
panelWhat it means What to do
LOW ENGINE OIL PRESSURE
When the key is turned to MAR the warning light comes on, but should go out as soon
as the engine is started.
After turning the ignition key to MAR, wait for about 2 seconds before starting the
engine.
The warning light switches on constantly together with a message on the display (for
versions/markets, where provided) when the system detects that engine oil pressure
is low.
IMPORTANT Do not use the vehicle until the failure has been solved.
IMPORTANT To find out the correct oil quantity, always check using the dipstick.
17)
DEGRADED ENGINE OIL (for versions/markets, where provided)
The warning light will turn on flashing together with a dedicated message on the
display (for versions/markets where provided).
Depending on the versions, the warning light flashing modes are as follows:
- for 1 minute every two hours;
- for 3 minute cycles with the warning light off for intervals of 5 seconds until oil is
changed.
After the initial warning, each time the engine is started up, the warning light will
continue to flash in the same mode, until the oil is changed. A specific message will
appear on the display (for versions/markets, where provided) in addition to the
warning light. If the warning light flashes, this does not mean that there is a fault, but
simply informs that it is now necessary to change the oil as a result of regular use of
the car. Engine oil deterioration is accelerated by:
- mainly town use of the car which makes the DPF regeneration process more
frequent;
- use of the vehicle for short drives, in which the engine does not have time to reach its
regular operating temperature;
- repeated interruptions of the regeneration process, signalled by the DPF warning
light switching on.Contact an Alfa Romeo
Dealership as soon as
possible.

KNOWING THE INSTRUMENT PANEL

Warning lights on
panelWhat it means What to do
ENGINE COOLANT TEMPERATURE TOO HIGH
The warning light switches on when the ignition key is
turned to MAR, but it should switch off after a few
seconds. The warning light turns on when the engine is
overheated.
The display shows the dedicated message.In normal driving conditions: stop the car, switch off the
engine and check that the water 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. Should the warning light turn on again
at the next start-up, contact an Alfa Romeo Dealership.
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. 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 Over demanding routes, it is advisable to
keep the engine on and slightly accelerated for a few
minutes before switching it off.
ALFA TCT FAILURE
(for versions/markets, where provided)
The warning light switches on when the ignition key is
turned to MAR, but it should switch off after a few
seconds.
The warning light flashes (together with a message in the
display and an acoustic signal) to indicate that the gearbox
is faulty.
The warning light can switch on even in the case of
transmission overheating, after a particularly demanding
use. In this case an engine performance limitation is
carried out.Contact an Alfa Romeo Dealership as soon as possible.
If it is necessary to start the engine with a transmission
failure, follow the procedure described in the "Alfa TCT"
paragraph, in chapter "Starting and driving".
SPEED LIMIT EXCEEDED
(for versions/markets, where provided)
The warning light switches on when the car exceeds the
speed limit value set in the Setup Menu (e.g. 120 km/h).
On some versions a message is shown along with a symbol
on the display, and an acoustic signal is emitted.

Warning lights on
panelWhat it means What to do
INJECTION/EOBD SYSTEM FAILURE
In normal conditions, when the ignition key is turned to MAR 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.18)
If the warning light remains on or switches on whilst driving, it
means that 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 goes out after the fault disappears: the indication
is stored in the system.Under these conditions, the vehicle can continue
travelling at moderate speed without demanding
excessive effort from the engine. Prolonged use
of the car with the warning light on constantly
may cause damage.
Contact an Alfa Romeo Dealership as soon as
possible.
Petrol engines only
If the warning light flashes, it means that the catalytic converter
may be damaged.In this case, 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.
GLOW PLUG HEATING/GLOW PLUG HEATING FAILURE (diesel
versions)
This warning light switches on when the key is turned to MAR. It will
switch off as soon as the heater plugs have reached a 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.
Glow plug preheating failure
The warning light will flash to indicate a failure in the glow plug
preheating system.Contact an Alfa Romeo Dealership as soon as
possible.

Warning lights on
panelWhat it means What to do
WATER IN DIESEL FILTER (Diesel versions)
The warning light switches on constantly when driving to indicate
the presence of water in the diesel filter.
19)
DPF CLEANING (particulate trap) in progress (diesel versions with
DPF only)
The warning light switches on when the ignition key is turned to
MAR, but it should switch off after a few seconds. The warning light
switches on constantly to indicate that the DPF system needs to
eliminate the trapped pollutants (particulate) through the
regeneration process.
The warning light does not come on during every DPF regeneration,
but only when driving conditions require that the driver is notified.
To turn off the warning light, keep the car in motion until the
regeneration process is over.
On average, the process lasts 15 minutes. Optimal conditions for
completing the process are achieved by travelling at 60 km/h with
engine speed above 2000 rpm.
When this warning light switches on, it does not indicate a vehicle
failure and thus it should not be taken to a workshop.
27)
iTPMS SYSTEM
The warning light switches on when the ignition key is turned to
MAR, but it should switch off after a few seconds.IMPORTANT Do not continue driving with one or
more flat tyres as handling may be compromised.
Stop the vehicle, avoiding sharp braking and
steering. Repair immediately using the dedicated
kit (see the "Replacing a wheel" paragraph in the
"In an emergency" section) and contact an Alfa
Romeo Dealership as soon as possible.
iTPMS failure/iTPMS temporarily deactivated
The warning light flashes for about 75 seconds and then stays on
constantly (see “Operating conditions” paragraph) to indicate that
the system is temporarily deactivated or faulty.
The system goes back to normal operation when the operating
conditions allow it. If this is not the case, carry out the Reset
procedure after restoring the normal operating conditions.If the malfunction warning persists, contact an
Alfa Romeo Dealership as soon as possible.

KNOWING THE INSTRUMENT PANEL

Warning lights on
panelWhat it means What to do
Low tyre pressure
The warning light switches on constantly to indicate that the tyre
pressure is lower than the recommended value, in order to
guarantee long tyre life and low fuel consumption, or to indicate a
slow loss of pressure.
In this way the iTPMS warns the driver that one or more tyres may
be flat and therefore probably punctured. In this case it is
advisable to restore the correct pressure value (see the "Wheels"
paragraph in the "Technical specifications" section).
Once the normal operating conditions of the vehicle are restored,
carry out the Reset procedure.In any situation in which the message on the
display is "See manual", it is ESSENTIAL to refer
to the contents of the "Wheels" paragraph in the
"Technical specifications" section, strictly
complying with the indications that you find
there.
IMPORTANT Do not continue driving with one or
more flat tyres as handling may be compromised.
Stop the vehicle, avoiding sharp braking and
steering.
ELECTRONIC STABILITY CONTROL (ESC) SYSTEM
When the ignition key is turned to MAR, the warning light switches
on, but should switch off as soon as the engine is started.
Intervention by the system is indicated by the flashing of the
warning light: it indicates that the car is in critical stability and grip
conditions.
If the warning light does not switch off, or if it stays on with the
engine running, this indicates an anomaly in the ESC system.Contact an Alfa Romeo Dealership as soon as
possible to have the problem diagnosed and
resolved.
ELECTRONIC STABILITY CONTROL (ESC) SYSTEM
ASR system failure
When the ignition key is turned to MAR, the warning light switches
on, but should switch off as soon as the engine is started.
The warning light will flash while driving to indicate that the ASR
system is intervening.
If the warning light does not switch off, or if it stays on with the
engine running, this indicates a malfunction of the ASR system.In this case, contact an Alfa Romeo Dealership as
soon as possible.
