IMPORTANT Depending on the trim
levels, the dial of the instruments may be
either light grey or black, with green or
red light.
A - Speedometer
IMPORTANT The rev counter may
have different clock values depending on
the different versions of the car.B - Mileage recorder with double
meter display (total and trip)
The display shows:
– the mileage on the first line (6 fig-
ures)
– the trip meter (4 figures) on the sec-
ond line.
Reset the partial km. and hold the push-
button pressed for approx. 1 second (A-
fig. 82).
IMPORTANT The trip meter reading
is not stored if the battery is disconnect-
ed.C - Check panel (fig. 83)
This electronic device checks and indi-
cates any inefficiencies that may adversely
affect running the car and driving safety.
The check panel mainly performs two
functions:
1) Warning lights check.

71
D - Rev counter
The danger zone (red) indicates exces-
sively high engine revs. Do not drive for
long periods with the pointer in this area.
With the engine at idle speed, the rev
counter may indicate a gradual or sudden
speed increase depending on the cases;
this is normal as it occurs in the normal
operation, for example when the climate
control compressor is engaged or the fan.
In particular a slow change in speed helps
preserve the battery charge.
IMPORTANT Depending on the ver-
sions/markets of the car, the rev counter
may have danger sectors (red) of differ-
ent size and with different top of scale
values.
IMPORTANT The electronic ignition
control system gradually shuts off the
flow of fuel when the engine is “over-
revving” resulting in a gradual loss of en-
gine power. Moving the ignition key to MARthe
following warning lights and displays turn
on and go out after approx. 6 seconds:
1- Light failure
2- Low brake fluid and/or handbrake
engaged
3- Front brake pad wear
4- Low engine oil level
5- Fuel reserve
6- Maximum engine coolant fluid tem-
perature
7- Mileage recorder displayAny faults are signalled by the turning
on of the corresponding warning light for
approx. 15 seconds after the end of the
check.
2) Doors and boot open warning.
With the ignition key at MAR, if a led
of the car symbol (10) lights up, the cor-
responding door or the boot has not been
shut properly.
To repeat the check, with the ignition
key in the MARposition and the engine
off, press the button (A-fig. 84).

E - Fuel gauge and reserve
warning light
This shows the amount of fuel left in
the fuel tank.
0Tank empty;
1Tank full (see "Refuelling" paragraph
in this section).
This warning light comes on to indicate
that about 9 litres of fuel are left in the
tank.
IMPORTANTUnder certain condi-
tions (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 is part of the operating logic of the
electronic control circuit to avoid highly
unstable readings due to swaying of the
fuel when travelling.F - Engine coolant temperature
gauge and maximum temperature
warning light (fig. 85)
This shows the temperature of the en-
gine coolant fluid and begins when the
fluid temperature exceeds about 50°C.
The pointer should normally be towards
the middle of the scale. If the pointer
reaches the higher temperature values
the request for vehicle performance
should be decreased.
The illumination of this warning light in-
dicates an excessive temperature of the
engine cooling fluid. In this case, stop the
car and contact Alfa Romeo Authorized
Services.IMPORTANT The temperature of the
engine coolant may rise towards the maxi-
mum values by obstruction or dirt on the
outer part of the engine cooling radiator.
In this case you are advised to inspect
and remove any obstructions and have
the outside of the radiator washed as
soon as possible.

G - The warning lights
IMPORTANT The presence of the
warning lights may vary depending on
the type of engine and trim level.
Insufficient brake fluid
and/or handbrake on
This warning light stays on for about 15
seconds, after the end of the check,
when the level of the brake fluid falls be-
low the minimum, possibly due to a leak-
age in the system and when the hand-
brake is engaged.
When the ignition key is turned to
MARthe warning light comes on but
must go out after approx. 6 seconds.
x
Air bag malfunction
When the ignition key is turned to the
MARposition the warning light will
come on and should go out as after
about. 4 seconds.
This warning light will come on perma-
nently when an anomaly affecting the Air
bag system is detected.¬
If the ¬warning light
does not turn on when
turning the ignition key to MAR or
if it stays on when travelling, this
could indicate a failure in safety re-
taining systems; under this condi-
tion air bags or pretensioners could
not trigger in the event of collision
or, in a restricted number of cases,
they could trigger accidentally.
Stop the car and contact Alfa
Romeo Authorized Services to
have the system checked immedi-
ately.
WARNING
If the warning light
comes on while driving
check if the handbrake is not en-
gaged. If the warning lights stays
on with the handbrake not engaged,
stop immediately and contact Alfa
Romeo Authorized Services.x
WARNING

74
If the warning light
comes on when the ve-
hicle is in movement,
switch the engine off immediate-
ly and contact Alfa Romeo Au-
thorized Services.v
Low engine oil level
This warning light stays on for approx.
15 seconds, after the check, when the
engine oil level is low.
With the ignition key at MAR, pressing
the check button, the warning light turns
on but must go out after approx. 6 sec-
onds.
The oil level is checked only pressing
the check button with the engine
stopped. If the engine is started during
the check, the check procedure is inter-
rupted.k
If the warning light
stays on after the
check, do not try to get
peak performance out of the en-
gine and top up the oil as soon
as possible.k
Insufficient oil pressure
This warning light should be out when
the engine is running.
When the ignition key is turned to the
MARposition the warning light comes
on and should go out as soon as the en-
gine is started. vLow battery charge
This warning light should be out when the
engine is running (a slight delay is permitted
when the engine is running at idle speed).
If the warning light comes on, Alfa
Romeo Authorized services should be con-
tacted immediately.
When the ignition key is moved to the
MARposition the warning light comes
on and should go out as soon as the en-
gine is started.w

75
Seat belts not fastened
When the ignition key is turned to
MARthe warning light turns on but it
must go out after approx. 15 seconds.
For versions/markets where applicable,
the warning light turns on permanently
when, with the key in the MARposi-
tion, the driver’s seat belt is not fastened
properly. This warning light comes on when the
brake pedal is pressed and the front
brake pads are found to be worn, have
them replaced as soon as possible. When
the ignition key is turned to MARthe
warning light comes on but must go out
after approx. 6 seconds.
IMPORTANT As the vehicle is fitted
with brake pad wear sensors for the front
wheels only, when these are replaced
check the back brake pads at the same
time.dAlfa Romeo CODE system
When the ignition key is turned to MAR
the warning light should come on and then
go out. If the warning lights stays on with
the key in the MARposition, it indicates
a possible failure: see “The Alfa Romeo
CODE system”.
IMPORTANT The turning on contem-
poraneously of warning lights and
indicates a failure of the Alfa Romeo
CODE system.

76
Engine control system
(EOBD) failure
(optional for versions/
markets where applicable)
Normally, when you turn the ignition
key to MAR, the warning light must
come on but must switch off when the
engine is running. It initially lights up to
indicate that the warning light is working.
If the warning light stays on permanent-
ly or comes on when the car is moving:
1)With a fixed light- indicates
that the supply/ ignition system is mal-
functioning that could cause high exhaust
emissions, possible loss of performance,
bad driveability and high consumptions.
In these conditions, you way continue
to drive while avoiding asking a lot from
the engine or high speeds. The prolonged
use of the car when this warning light is
on could cause damage. Contact an Alfa
Romeo Authorized Service Station as
soon as possible. The warning light turns
off if the malfunction disappears, howev-
er the system stores the warning anyhow.
U
2)Flashing light - indicates that the
catalytic converter could be damaged
(see paragraph on “EOBD System” in
this chapter).
If the warning light is on and flashing,
take your foot off the accelerator and dri-
ve at low speeds until the warning light
stops flashing; continue travelling at a
moderate speed trying to avoid driving
conditions that could cause the warning
light to flash again. Contact an Alfa
Romeo Authorized Service Station as
soon as possible.
If, when turning the ig-
nition key to MAR, the
Uwarning light does
not switch on or if, when dri-
ving, the light flashes or emits a
fixed light, contact an Alfa
Romeo Authorized Service Sta-
tion as soon as possible.
Engine control system
(versions for markets where
applicable)
1) In normal conditions, turning the ig-
nition key to MAR, the dial warning
light turns on but it should go off when
the engine has started. The initial turning
on indicates that the warning light is
working properly.
2) If the warning light stays on or turns
on when travelling, it indicates a fault in
the supply /ignition system which could
cause high exhaust emissions, possible
lack of performance, poor handling and
high consumption levels.
In these conditions, it is possible to con-
tinue driving without however demanding
heavy effort or high speeds.
Prolonged use of the car with the warn-
ing light on may cause damage. Contact
an Alfa Romeo Authorized Service as
soon as possible.
The warning light turns off if the fault
disappears, but it is still stored by the sys-
tem.
U

77
Faulty ABS anti
wheel-locking
This warning light comes on when the
system is inefficient. In this case normal
braking is ensured without though, mak-
ing use of the ABS system. Alfa Romeo
Authorized Services should however be
contacted as soon as possible.
When the ignition key is turned to
MARthe warning light comes on but
must go out after approx. 4 seconds.>
Presence of water
in the fuel oil filter
(JTD 20V Multijet versions)
When the ignition key is turned to the
MARposition the warning light should
come on and must go out after approx. 4
seconds.
The warning light switches on fixed
when driving, to indicate the presence of
water in the fuel oil filter.
In case the indicator light switches on,
even if just for a few seconds, we recom-
mend to contact an Alfa Romeo Autho-
rised Service as soon as possible in order
to purge the water from the fuel oil filter
and avoid severe damages to the injec-
tion pump and to the fuel oil supply cir-
cuit as well as the engine irregular opera-
tion.
c
Glowplugs
(JTD 20V Multijet versions)
The warning light comes on
when the ignition key is turned to MAR
position. When the glowplugs have
reached the established temperature the
warning light will go out. Start the en-
gine as soon as the warning light has
gone out.
For versions/markets where applica-
ble, the warning light flashes for approx.
30 seconds after starting the engine
meaning that there is a fault to the glow
plug warning system, in which case,
contact Alfa Romeo Authorized Services.
With a high ambient temperature the
warning light may turn on imperceptibly.
m
The car is fitted with an
electronic braking device
(EDB). If the
>andxwarning
lights turn on at the same time, this
means that there is an EBD system
fault; in this case violent braking
may be accompanied by early rear
wheel locking, with the possibility
of skidding. Drive the car ex-
tremely carefully to the nearest
Authorized Alfa Romeo workshop
to have the system checked.
WARNING

78
LLeft-hand direction
indicator (intermittent)
This warning light comes on when the
control lever is moved downwards or, to-
gether with the right-hand warning light,
when the hazard warning lights are
switched on. R
Sidelights
This warning light comes on when the
sidelights are switched on.3
Right-hand direction
indicator (intermittent)
This warning light comes on when the
control lever is moved upwards or, togeth-
er with the left-hand warning light, when
the hazard warning lights are switched
on.E
Lights failure
The warning light stays on for about
15 seconds, after the check, when a fail-
ure is detected on one of the following
lights:
– low beam headlights
– high beam headlights
– flashing (only gas discharge headlights)
– side/taillights
– direction indicators
– brake lights (stop lights)
– third stop light
– rear fog guards
– number plate lights.
The warning of a fault may mean one
or more blown bulb, a burnt fuse or cut
off connection.
Turning the key to MARthe warning
light turns on, but it should go out after
about 5 seconds.The turning on of only
the
>warning light with
the engine running normally indi-
cates a fault to the ABS system
only. In this case the braking sys-
tem is still efficient, though with-
out the aid of the anti-lock device.
Under these conditions perfor-
mance of the EBD system may be
reduced. in this case too, you are
advised to go immediately to the
nearest Authorized Alfa Romeo
workshop, driving in such a way
as to avoid sharp braking, to have
the system checked over.
WARNING

79
Main-beam headlights
This warning light comes on when the
main-beam is switched on.
Cruise Control
(on request for versions/
markets where applicable)
The warning light turns on, with the
control switch in the ONposition, when
the device starts to act on the engine.
1VDC System (Vehicle
Dynamics Control)
(on request for versions/
markets where applicable)
Turning the ignition key to MAR, the
warning light on the instrument cluster
lights up and must go out after about 4
seconds.
If the warning light does not go out or s-
tays on when travelling, contact Autho-
rised Alfa Romeo Services. Although the
absence of the VDC function does not af-
fect the car safety, it is however recom-
mended to drive at moderate speed.
Flashing of the warning light when travel-
ling means that the VDC system has cut in.
áPassenger’s Air bag
deactivated
This warning light turns on when the
passenger’s Air bag is deactivated.
Warning light Findi-
cates also warning light
¬failure. This is indicated by in-
termittent flashing, over 4 sec-
onds, of warning light F. In this
event, warning light ¬could be
not up to indicate restraint system
failures, if any. Stop the car and
contact Authorized Alfa Romeo
Services have the system checked.
