If the display shows an anomaly message, see paragraph
“Warning lights and indications” in this chapter.
INITIAL CHECK
By turning the ignition key to the MARposition, the Infocenter display will show the message CHECK ACTIVE: this indicates the start of the
diagnosis phase for all the electronic systems available on the vehicle; this phase lasts a few seconds (in diesel versions only, the Infocenter
display is able to provide the engine oil level indication too, see following paragraph “Engine oil level check”). If, during this phase, no anom-
aly is found and after the engine has been started, the display will show the message CHECK OK.

WARNING LIGHTS AND INDICATIONSGENERAL WARNING
The failure indicationsshown on the Infocenter display, together with the buzzer (adjustable) and the turning on of the relevant warn-
ing light (if available), are accompanied by specific warning messages(e.g. “Go to dealer”, “Switch off eng., do not proceed”, etc…).
These warnings are concise and precautionaryand are intended to suggest the prompt actionthat the driver should take when a
failure occurs. However, these warnings are not to be considered exhaustive and/or alternative to the prescriptions of this Owner’s Manual,
which must always be read over carefully. When an anomaly occurs always refer to the contents of this chapter.
WARNINGWhen an anomaly occurs, the Infocenter display reaches its maximum brightness. By pressing button
â
the warning messages
disappear and the symbol referring to the failure warning is reduced to an icon in the right bottom area of the display.
WARNINGThe anomaly warnings that appear on the Infocenter display are divided into two categories: very serious and serious anomalies.
Very serious anomalies are displayed indefinitely, by interrupting any message previously shown on the display, and are proposed again every
time the ignition key is turned to MAR, until the malfunction is eliminated. Moreover, the “cycle” can be interrupted by pressing button
â
: in
this case, the symbol referring to the anomaly will be shown in the right bottom area of the display until the malfunction is eliminated.
Serious anomalies are displayed for about 20 seconds and then disappear, but they are proposed again every time the ignition key in turned
to MAR. At the end of the display cycle, equal to about 20 seconds, or when button
â
is pressed, the symbol referring to the anomaly will
be shown in the right bottom area of the display until the malfunction is eliminated.

Warning light Message
on displayY
ALFA ROMEO CODE SYSTEMWhen the ignition key is turned to MAR, the warning light on the check panel should flash only
once and then go out. If the warning light stays on with the key at MAR, this indicates a possible
failure: see “Alfa Romeo CODE System”.
WARNINGThe turning on at the same time of
U
and
Y
warning lights indicates a failure of
the Alfa Romeo CODE System.
If with the engine running, the
Y
warning light flashes, this means that the car is not protected
by the engine inhibitor device (see “Alfa Romeo CODE system” in this chapter). Contact Alfa Romeo
Authorized Services to have all the keys memorised.
POSSIBLE PRESENCE OF ICE ON THE ROADWhen the outside temperature is below or equal to 3° C, in order to warn the driver on the pres-
ence of ice on the road, message + symbol are displayed accompanied by the related buzz.
The buzz lasts about 2 seconds while the message is displayed for about 10 seconds. After this
period, only the symbol is displayed until the temperature does not go over 6° C or until the en-
gine stops.
If during travelling, after the presence of ice on the road has been signalled, should temperature
rise over 6° C the symbol will go off and should temperature fall again to 3° C, a new message +
symbol will be displayed accompanied by the buzz.

INEFFICIENT ABS SYSTEMWhen the ignition key is turned to MAR, the warning light comes on but must go out after a
few seconds.
This warning light comes on (together with the message + symbol, where required, on the display)
when the system is inefficient. In this case, normal braking is ensured, though without making use
of the ABS system. Caution is recommended, especially in cases of less than perfect grip. In any
case, contact Alfa Romeo Authorized Services as soon as possible.Inefficient EBD electronic braking distributor
x>+
The vehicle is equipped with an electronic braking distributor (EBD). Si-
multaneous lighting of dial warning lights
>
and
x
(together with the
message + symbol on the display) with the engine running indicates an EBD
system failure; in this case, any sudden braking action can cause early locking
of rear wheels, with possible sideslip. Drive very carefully and go immediately
to the nearest Alfa Romeo Authorized Service to have the system checked.
