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

IGNITION SWITCH
The key can be turned to three different positions fig. 21:
❍STOP: engine off, key can be extracted, steering locked. Some
electric devices (e.g. car radio, central door locking system,
alarm, etc.) can work;
❍MAR: driving position. All electric devices can work;
❍ON: starting the engine.
The ignition switch is fitted with an electronic safety system that
requires the ignition key to be turned back to STOP if the engine
will not start, before the starting operation can be repeated.

EOBD SYSTEM
(European On Board Diagnosis)
(for versions/markets, where provided)
The aim of the EOBD (European On Board Diagnosis) system is to:
❍to monitor system efficiency;
❍indicate an increase in emissions;
❍to warn of the need to replace deteriorated components.
The car also has a diagnostic connector that can be interfaced
with appropriate tools, which makes it possible to read the error
codes stored in the electronic control units together with a series
of specific parameters for engine operation and diagnosis. This
check can also be carried out by the traffic police.
IMPORTANT After eliminating a fault, to check the system com-
pletely, Alfa Romeo Authorized Services are obliged to run tests
and, if necessary, road tests which may also call for a long journey.
DUAL PINION ACTIVE STEERING
This only operates with the key turned to MAR and the engine start-
ed. The steering allows the force required at the steering wheel
to be adjusted to suit driving conditions. The different power as-
sistance modes can be selected via the d,n,a positions of the"Alfa
DNA System" lever (see paragraph entitled "Alfa DNA System").
IMPORTANT The steering system will need to be initialised after
disconnecting the battery. A warning light will come on to indicate
this. Simply turn the steering wheel all the way from one end to the
other or simply drive in a straight line for a few hundred metres.
Under no circumstances should aftermarket op-
erations be carried out involving steering system
or steering column modifications (e.g. installation
of anti-theft device). This could negatively affect perfor-
mance and safety, invalidate the warranty, cause serious
safety problems and also result in non-compliance of the
car with type-approval requirements.
