REV COUNTERThe rev. counter shows engine rpm. The
needle pointed to the danger area (red) in-
dicates excessive high engine speed. Do not
drive for long periods with the needle in this
area.
WARNINGThe electronic injection con-
trol system gradually shuts off the flow of
fuel when the engine is “over-revving” re-
sulting in a gradual loss of engine power.
The rev counter may, when the engine is
idling, indicate gradual or sudden increase
of engine revs as the case may be; such be-
haviour is normal and must not be inter-
preted as a faulty condition as it occurs dur-
ing normal operation, for instance when
climate control or electric fan are switched
on. In particular, slow revs variation helps
keep the battery charged.
FUEL GAUGE AND RESERVE
WARNING LIGHTThis shows the amount of fuel left in the
fuel tank.
This warning light
ç
comes on to indicate
that approximately 7 litres of fuel are left in
the tank.
WARNINGUnder certain conditions
(heavy slopes, for instance), the reading on
the gauge may differ from the actual
amount of fuel in the tank and changes in
level may be indicated late.
This condition falls within the operation log-
ics of the electronic control circuit to avoid
highly unstable readings due to swaying of
the fuel when travelling.
WARNINGRefuelling shall always be
performed with engine off and ignition key
to STOP. If the engine is off but the key
is to MAR, a wrong fuel level could tem-
porarily be indicated. This is due to the in-
ternal system control logic and cannot be
considered as a system malfunctioning.
ENGINE COOLANT
TEMPERATURE GAUGE AND
MAXIMUM TEMPERATURE
WARNING LIGHTThis shows the temperature of the engine
coolant fluid and begins when the fluid tem-
perature exceeds approx. 50°C.
The pointer should normally be towards
the middle of the scale. If the pointer
reaches the higher temperature values of
the scale (red area), the request for vehi-
cle performance should be decreased.
The illumination of the warning light
ç
(together with the message shown by the
Infocenter display) indicates an excessive
temperature of the engine cooling fluid. In
this case, stop the car and contact Alfa
Romeo Authorized Services.
WARNINGThe temperature of the en-
gine coolant may rise towards the maximum
values (red) when the vehicle is driven at
low speeds, especially when the ambient air
temperature is high. In this case, the vehi-
cle should be stopped and the engine
switched off for a few minutes after which
the journey can be resumed, preferably at
a higher speed.

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.
