Excessive engine coolant
temperature (red)
This warning light comes on when the ignition key is
turned to MAR, but it should go off after a few seconds.
The warning light turns on when the engine is overheated. The dis-
play will show the dedicated message. If the warning light comes
on, proceed as follows:
❍during normal travel: stop the car, stop the engine and check
that the water level in the reservoir is not under the MIN line.
In this case, 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 references
on the reservoir. Also check for leaks. If the warning light comes
on again at the next engine start-up, contact your nearest Al-
fa Romeo Authorised Service.
❍In the case of demanding use (e.g. towing trailers uphill or
car at full load): slow down and stop the car if the warning light
stays on. Stop for 2 or 3 minutes with the engine running and
slightly accelerated to favour better coolant circulation. Then
stop the engine. Check the correct fluid level as described pre-
viously.
IMPORTANT Over demanding routes, it is advisable to keep the
engine on and slightly accelerated for a few minutes before switch-
ing it off.

Electric power steering failure (red)
This warning light comes on when the ignition key is
turned to MAR, but it should go off after a few sec-
onds.
If the warning light (or symbol on the display) remains on, you will
not have steering assistance and the effort required to operate
the steering wheel will be increased. Steering is, however, possi-
ble. In this case contact your nearest Alfa Romeo Authorised Ser-
vice. The display will show the dedicated message.g
Start&Stop system deactivation
(amber)
The warning light comes on when the Start&Stop sys-
tem is deactivated by pressing the button on the auxil-
iary control panel next to the steering wheel. On some versions the
display shows the associated message.T

EOBD/injection system failure
(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, this
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.
On certain versions the dedicated message is displayed.
Under these conditions, the vehicle can continue travelling at mod-
erate speed without demanding excessive effort from the engine.
Prolonged use of the car with the warning light on may cause dam-
age. Contact your nearest Alfa Romeo Authorised Service as soon
as possible.
The warning light goes out after the fault is cleared, and the indi-
cation is stored in the system.

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 con-
tact an Alfa Romeo Authorised Service as soon as possible.

22GETTING TO KNOW YOUR CAR
Speed limit exceeded (red)
(for versions/markets, where provided)
This warning light (for versions/markets, where pro-
vided) comes on when the vehicle speed exceeds 120
km/h.
When the vehicle exceeds the speed limit set in the Setup Menu
(e.g. 120 km/h), on some versions a message and symbol are
shown in the display and a buzzer sounds.
X
General failure (amber)
(for versions/markets, where provided)
On some versions, this warning light comes on under the
following circumstances:
External lights failure
See description of 6warning light.
Brake lights failure
See description of “brake lights failure”.
Fuel lock

è
Particulate trap filter blocked
(Diesel with DPF versions) (amber)
When the ignition key is turned to MAR, the warning
light switches on but it must switch off after a few seconds.
The warning light comes on constantly to notify the driver that
the DPF system needs to eliminate captured pollutants (particu-
late) by the regeneration process. The warning light does not come
on during every DPF regeneration, but only when driving conditions
require notification of the driver. To switch the warning light off,
the car must stay in motion until regeneration has been complet-
ed. The process normally takes about 15 minutes. The optimum
conditions to end the process are achieved by keeping the car in
motion up to 60km/h with an engine speed higher than 2,000
rpm. This light coming on is not a car defect and therefore the car
does not need to go to the workshop.
A specific message will appear on the display when the warning
light comes on (for versions/markets, where provided).
h
Always drive at a speed appropriate to the traffic
conditions, the weather and speed limits. The en-
gine may be turned off while the DPF light is on;
however, repeated interruption of the regeneration process
may result in premature exhaustion of engine oil. For this
reason it is always advisable to wait for the light to go
off before turning off the engine, following the instruc-
tions appearing above. It is not advisable to complete DPF
regeneration with the vehicle stationary.

Insufficient tyre inflation pressure
(for versions/markets, where provided)
This warning light (or symbol in the display) comes on
(on some versions together with a message on the dis-
play) (together with the sounding of a buzzer) if the tyre infla-
tion pressure of one or more tyres goes below a preset value. In
this way the T.P.M.S. system warns the driver that one or more
tyres may be dangerously flat and liable to puncture.
IMPORTANT Do not continue driving with one or more tyres flat
as vehicle driveability may be compromised. Stop the car, avoid-
ing harsh braking or steering manoeuvres. Replace the wheel im-
mediately with the spare wheel (for versions/markets, where pro-
vided) or carry out a repair using the dedicated kit (see the para-
graph on “Replacing a wheel” in chapter 4) and contact an Alfa
Romeo Authorised Service as soon as possible.n
