WARNING LIGHTS AND MESSAGES
WARNING The warning light switches on together with a dedicated message and/or acoustic signal when applicable. These
indications are indicative and precautionary and as such must not be considered as exhaustive and/or alternative to the
information contained in the Owner Handbook, which you are advised to read carefully in all cases. Always refer to the
information in this section in the event of a failure indication.
IMPORTANT Failure indications displayed are divided into two categories: very serious and less serious failures. Serious faults
are indicated by a repeated and prolonged warning "cycle". Less serious faults are indicated by warning "cycle" with a shorter
duration. The display cycle of both categories can be interrupted. The instrument panel warning light will stay on until the cause
of the malfunction is eliminated.

WARNING
59) If thewarning light does not switch on when the key is turned to MAR-ON or if it stays on when driving (together
with the message on the display), there may 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 the dedicated Alfa Romeo Dealership to have the system checked
immediately.
60) Failure of the
warning light is signalled by the flashing for longer than the usual 4 seconds of thewarning
light. In addition, the airbag system automatically disables the passenger side airbag. In this case, the
warning
light may not indicate a fault in the restraint systems. Before proceeding, contact the dedicated Alfa Romeo
Dealership to have the system checked immediately.

Warning lights on
panelWhat it means What to do
amberINJECTION/EOBD SYSTEM FAILURE
In normal conditions, when the ignition key is turned to
MAR-ON the warning light switches on, but 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.5)
If the warning light stays on or switches on when driving,
it means that the injection system is not working
properly; in particular, if the warning light comes on
constantly, this indicates a malfunction in the supply/
ignition system that could cause excessive exhaust
emissions, a possible loss of performance, poor
driveability and high fuel consumption.
On some versions, the display shows the dedicated
message.
The warning light switches off if the malfunction
disappears, but it is still stored by the system.Under these conditions, you may continue
travelling at a moderate speed without
demanding excessive effort from the
engine. Prolonged use of the car with the
warning light on constantly may cause
damage.
Contact the dedicated Alfa Romeo
Dealership as soon as possible.
If the warning light flashes, it means that the catalytic
converter may be damaged.In this case, it is necessary to 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 the dedicated Alfa Romeo
Dealership as soon as possible.

Low tyre pressure - See manual
The warning light switches on, together with a
dedicated message on the display, to indicate that
the tyre pressure is lower than the recommended
value and/or that slow pressure loss is occurring. In
these circumstances, optimal tyre duration and fuel
consumption may not be guaranteed.
Should two or more tyres be in the condition
mentioned above, the display will show the
indications corresponding to each tyre in
sequence.In any situation in which the message on the
display is "See manual", it is ESSENTIAL to refer
to the contents of the "Wheel" paragraph in the
"Technical data" chapter, strictly complying with
