Hot engine coolant (red)
When the ignition key is turned to MAR, the warning
light turns on but should go off after a few seconds.
The warning light turns on when the engine is over-
heated. A specific message will be shown on the display.
If the warning light comes on, proceed as follows:
❍when driving normally: stop the car, switch off the engine and
check that the water level in the reservoir is not below the MIN
mark. If it is not, wait for a few minutes 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.
Also visually check for leaks. If the warning light comes on again
at the next engine start-up, contact Alfa Romeo Authorized Ser-
vices.
❍if the car is used under demanding conditions (e.g. towing trail-
ers uphill or fully loaded): slow down and, if the light stays on,
stop the car. Stop for two or three minutes with the engine run-
ning and slightly accelerated to assist better coolant circulation.
Then switch the engine off. Check correct fluid level as described
above.
IMPORTANT On particularly demanding journeys, it is advisable to
keep the engine on and slightly accelerated for a few minutes be-
fore switching it off.
u
Door open (red)
(for versions/markets, where provided)
The warning light (or symbol on the display) comes
on when one or more doors or the boot are not perfectly
closed. An acoustic signal is activated with the doors open and
the car moving. On some versions, the warning light (or symbol
on the display) also lights up when the bonnet is not perfectly
closed.´
EOBD/injection system fault (amber)
Under normal conditions, the warning light comes on
when the ignition key is turned to MAR, but should
go off as soon as the engine is started.
If the warning light remains on or comes on whilst driving, that
means that the injection system is not working properly; in partic-
ular, if the warning light comes on constantly, this indicates a mal-
function in the supply/ignition system that could cause excessive
exhaust emissions, a possible loss of performance, poor driveabil-
ity and high fuel consumption.
A specific message is displayed on certain versions.
Under these conditions, you can continue travelling at moderate
speed without demanding excessive effort from the engine. Pro-
longed use of the car with the warning light on may cause dam-
age. Contact Alfa Romeo Authorized Services as soon as possible.
The warning light goes out after the fault disappears, but the in-
dication is stored in the system.U

er system fault. In this case, contact your nearest Alfa Romeo Au-
thorized Services.
á
NOTE (petrol engines only)
If the warning light is flashing, this indicates that the catalytic
converter may be damaged.
If the warning light comes on intermittently, release the accelera-
tor 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 Authorised Service Provider as soon as possible.
Contact Alfa Romeo Authorized Services as soon as
possible if the
Uwarning light does not light up
or if, while travelling, the warning light comes on
either fixed or blinking (in combination with a message

Fuel reser ve – Limited range (amber)
This warning light comes on when about 8 to 10 litres
of fuel are left in the tank. A warning message will ap-
pear on the display (some versions only) when the re-
maining range less than approximately 50 km (or equivalent in
miles).K
If the warning light flashes with the car in motion,
contact Alfa Romeo Authorized Services.
Cruise Control (green)
(for versions/markets, where provided)
The warning light comes on when the key is turned to
MAR, but should go out after a few seconds if the Cruise
Control function is off. The warning light comes on when the Cruise
Control wheel is turned to the ON position (see the “Cruise Con-
trol” paragraph in this chapter). A specific message appears on the
display.Ü
DPF (particulate trap) cleaning in
progress (diesel versions with DPF
only) (amber)
When the ignition key is turned to MAR, the warning light
turns on but should go off after a few seconds. The warning light
stays on constantly to notify the driver that the DPF system needs
to eliminate captured pollutants (particulate) by the regeneration
process.
The warning light does not come on during every DPF regenera-
tion, but only when driving conditions require notification to the dri-
ver. The warning light will go off if the car stays in motion until
regeneration has been completed.
The process normally takes about 15 minutes. Optimal conditions
for completing the process are achieved by travelling at 60 km/h
with engine revs above 2000 rpm.
Operation of this warning light does not indicate a fault and the car
does not need to be taken to a workshop. A specific message will
appear on the display when the warning light comes on (for ver-
sions/markets where provided).

Speed limit exceeded (red)
(for versions/markets, where provided)
The warning light (for versions/markets where pro-
vided) comes on when the speed exceeds 120 km/h.
When the car exceeds the speed limit set in the setup Menu (e.g.
120 km/h), on some versions a message and a symbol are shown
in the display and an acoustic signal is activated.
X
Always drive at a speed appropriate to the traffic
conditions, the weather and the laws in force. The
engine may be turned off while the DPF light is on;
however, repeated interruption of the regeneration process
may result in premature degradation of the engine oil.
For this reason, it is always advisable to wait for the light
to go off before turning off the engine, following the in-
structions appearing above. It is not a good idea to com-
plete DPF regeneration with the vehicle stationary.Generic fault (amber)

Contact Alfa Romeo Authorized Services as soon as possi-
ble to eliminate the fault.
