TO INCREASE THE MEMORISED
SPEEDThe speed memorised can be increased
in two ways:
1)pressing the accelerator and then mem-
orising the new speed reached (turning the
ring (B) for more than three seconds);
or
2)momentaneously turning the ring (B)
to (+): each pulse of the ring will correspond
to a slight increase in speed (about 1.5
km/h) while pressing continuously will cor-
respond to a continuous speed increase. Re-
leasing the ring (B) the new speed will be
memorised automatically.TO REDUCE THE MEMORISED
SPEEDThe speed memorised can be reduced in
two ways:
1)disengaging the device (for instance
pressing the brake pedal) and then memo-
rising the new speed (turning the ring (B)
to (+) for at least three seconds);
2)keeping the ring pressed (B) at (–)
until reaching the new speed which will be
memorised automatically.
RESETTING THE MEMORISED
SPEEDThe memorised speed is automatically re-
set turning off the engine or moving the ring
(A) to OFF.
When travelling with the
cruise control on, do not
move the gearshift lever to neutral.
WARNING
The cruise control may only
be engaged at speeds be-
tween 30 and 190 km/h.
WARNING
It is advisable to engage
the cruise control only
when the conditions of the traffic
or road so permit under completely
safe conditions: i.e.: straight and
dry roads, dual carriageways or
motorways, flowing traffic and
smooth road surface. Do not en-
gage the device in town or in
heavy traffic conditions.
WARNING
If the device is faulty or
not working, turn the ring
(A) to OFF and contact Alfa Romeo
Authorized Services after checking
that the protection fuse is intact.

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.
