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.

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
(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 begins to flash (on some versions, the
symbol and a message appear on the display) to indicate
a gearbox fault.
On the display, together with the warning light, the
following messages can be shown:
“Check transmission” message;
“Gear not available” message;
“Manual mode not available” message;
“Automatic mode not available” message;
“Required manoeuvre incompatibility” message;
“Clutch overheating” message.
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".
Clutch overheating
The
the display) switches on
to indicate clutch overheating.In this case limit the gear changes and/or change the
condition of use, until normal operating conditions are
restored. If the driver continues, the
warning light (or symbol on the display) will switch off and
the
will switch on,
on the display, to indicate an
automatic transmission fault. In this case, stop
immediately, operate the handbrake, and wait for
5 minutes: after this, transmission operation conditions
will be restored. If the fault persists, contact an Alfa
Romeo Dealership as soon as possible.

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
(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.
13)
DEGRADED ENGINE OIL (where provided)
The warning light will turn on flashing and, on some versions, with a specific message
on the display.
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. On some versions, the
display shows a dedicated message together with 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.

FUEL RESERVE/LIMITED RANGE
The warning light turns on when about 5 - 7 litres of fuel
are left in the tank.
When the remaining range is lower than approx. 50 km
(or equivalent value in miles), on some versions the
display will show a warning message.

REAR FOG LIGHT
The warning light switches on when the rear fog light is
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
seconds.
The warning light switches on to indicate a system fault.
In this case the braking system maintains its efficiency
unaltered but without the advantage of the ABS system.
The display shows the dedicated message.Drive carefully and contact an Alfa Romeo Dealership as
soon as possible.
START&STOP SYSTEM DEACTIVATION
The warning light switches on when the Start&Stop
system is deactivated (for more information, see the
paragraph “Start&Stop System” in the chapter “Starting
and driving”).
On some versions the display shows the dedicated
message.

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.14)
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.
WARNING 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.
15)
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.

Warning lights on
panelWhat it means What to do
TPMS SYSTEM
Low tyre pressure
The warning light (or symbol on the display) switches on (on some
versions together with a message on the display) (together with
an acoustic signal) if the pressure in one or more tyres drops
below a preset threshold.
In this way the TPMS warns the driver that one or more tyres may
be dangerously flat and liable to puncture.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. Replace the wheel
immediately with the spare wheel (where
provided) or carry out a prompt repair using the
dedicated kit (see the paragraph on “Replacing a
wheel” in chapter “In an emergency”) and contact
Alfa Romeo Dealership as soon as possible.
TPMS failure
This warning light switches on (on some versions together with a
message on the display) when a TPMS fault is detected.
Should one or more wheels be fitted without sensors, the display
will show a warning message until initial conditions are restored.Contact an Alfa Romeo Dealership as soon as
possible.
Check tyre pressure
The warning light switches on (on some versions together with a
message in the display) to indicate that the tyre pressure is below
the value recommended to guarantee long tyre life and low fuel
consumption. It may also indicate a slow loss of pressure.
Should two or more tyres be in the condition mentioned above,
the display will show the indications corresponding to each tyre in
sequence. In this case it is advisable to restore the correct
pressure value
