Engine coolant overheating
(red)
Turning the key to the MAR position illuminates the warning light, but it
should switch off after a few seconds.
The warning light turns on when the engine is overheated.
The display will show the dedicated message.
If the warning light comes on when driving, 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, 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. Also
check visually for leakages. If the warning light comes on again at
the next engine start-up, contact Alfa Romeo Authorised Services.
❒if the vehicle is used under demanding conditions(e.g.
towing trailers uphill or fully loaded): slow down and, if the warning
light stays on, stop the car. Wait for 2 or 3 minutes with the engine
running and slightly accelerated to further favour the coolant
circulation. Then stop the engine. Check the correct fluid level 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.
Doors not closed correctly
(red)(for versions/markets, where provided)
The warning light (or symbol on the display) lights up when one or
more doors or the tailgate are not closed correctly. 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 closed correctly.EOBD/injection system failure
(amber)
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.
If the warning light remains on or switches on whilst driving, the
injection system is not working properly; in particular, if the warning
light switches 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.
A specific message is displayed on certain versions.
Under these conditions, you may continue travelling at moderate speed
without demanding excessive effort from the engine. Prolonged use of
the car with the warning light on may cause damage.
Contact Alfa Romeo Authorized Services as soon as possible.

Glow plug preheating
(diesel versions) (amber)
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 an extremely short time.Glow plug preheating failure
(diesel versions)The warning light will flash (a message will appear on the display, on
some versions) to indicate a fault in the glow plugs preheating system.
Contact Alfa Romeo Authorized Services as soon as possible to
eliminate the fault.
Water in diesel filter
(diesel versions) (amber)
The warning light remains on constantly when driving (together with a
message in the display), to indicate the presence of water in the
diesel filter.
The presence of water in the fuel system circuit may cause
severe damage to the injection system and irregular engine
operation. If the warning light
comes on in the
instrument panel (together with a message in the display) contact Alfa
Romeo Authorized Services as soon as possible to bleed the system.
Water may have entered the tank if this appears immediately after
refuelling: if this happens, switch the engine off immediately and
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 ring nut is turned
to the ON position (see the “Cruise Control” paragraph in this section).
The display will show the dedicated message.DPF (diesel particulate filter)
cleaning in progress (only
diesel versions with DPF)
(amber)
Turning the key to the MAR position illuminates the warning light, 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 switch the warning light off, the car must be kept moving until the
regeneration process is completed.
On average, the process lasts fifteen minutes. Optimal conditions for
completing the process are achieved by travelling at 60 km/h with
engine revs above 2000 rpm.
When this warning light switches on, it does not indicate a car failure
and thus it should not be taken to a workshop.
On some versions, together with the warning light, the display shows a
dedicated message.
The driving speed must always be suitable for traffic
and weather conditions and the driver must always
comply with the Highway Code. The engine can be
stopped even if the DPF warning light is on: however, repeated
interruptions of the regeneration process could cause premature
deterioration of the engine oil. For this reason, always wait until
the warning light switches off before stopping the engine as
described above. It is not advisable to complete DPF regeneration
with the car stationary.Speed limit exceeded (red)(for versions/markets, where provided)
This warning light (for versions/markets, where provided) comes on
when the vehicle speed exceeds 120 km/h.
When the car exceeds the speed limit set in the Set-up 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.
