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".

switched on.
ABS FAILURE
The warning light switches on when the ignition key is
turned to MAR, but it should switch off after a few

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.

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.

panelWhat it means What to do
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.
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.
