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

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.

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.
WARNING

91
ADDITIONAL HEATER
(Optional, for diesel versions, where
applicable)
The additional heater makes it possible
to integrate heating of the engine coolant
fluid, immediately after starting the en-
gine and when travelling, to more quickly
reach and maintain the optimum operat-
ing temperature of the engine and pas-
senger compartment heater.
The device works completely automati-
cally and it is activated only when the en-
gine is running with an outside tempera-
ture of +5°C or less and a coolant fluid
temperature below 60°C.
When the coolant fluid reaches 61°C,
the electronic control unit reduces the
power of the burner and stops the heater
when a temperature of 72°C is reached,
reactivating it automatically when the flu-
id temperature falls below 60°C. Con-
versely, if after reducing the power of the
burner, the fluid temperature begins to
fall, the control unit cuts in to restore full
power.The system comprises:
– a fuel oil burner for heating the water
and a combustion gas exhaust silencer.
– A batching pump connected to the car
reservoir pipes to supply the burner.
– An electronic control unit for control-
ling burner adjustment.
– An outside temperature sensor.IMPORTANT The heater is fitted with
a thermal limiting device which cuts off
combustion in the event of overheating
due to lack/leaks of coolant fluid.
The heater is also protected by the auto-
matic fuel cut-off switch, which shuts off
the fuel in the event of a crash of a cer-
tain size: to see how this works see the
“automatic fuel cut-off switch” para-
graph.

AUTOMATIC FUEL CUT-OFF SWITCH
The car is equipped with a safety switch
which is triggered in the event of a crash
to interrupt the flow of fuel and stopping
the engine as a consequence. This also
prevents fuel leaks due to fuel lines
breaking.If no leaks or damages to electric de-
vices (e.g.: headlights) are found and the
car can be restarted, reactivate the fuel
cut-off switch. Follow the instructions giv-
en below.
If, after an accident, you
can smell petrol or see
that the fuel feed system is leak-
ing, do not reset the switches to
avoid the risk of fire.
WARNING
After the crash, remember to turn the ig-
nition key to STOPto prevent the bat-
tery running down.

134
In addition to the notes
and specifications given
below we recommend
that, during the initial period, y-
ou do not drive to full vehicle
performance (for example exces-
sive acceleration, long journeys
at top speed, hard braking etc.).
STARTING
THE ENGINE
IMPORTANT The car is fitted with an
electronic engine lock device. if the en-
gine fails to start see “The Alfa Romeo
CODE system”.The ignition switch is fitted with a safety
device which obliges the driver to return
the ignition key to the STOPposition be-
fore repeating the starting operation if
the engine does not start immediately.
Similarly, when the engine is running,
the device prevents the key being moved
fromMARto the AVV position.
PROCEDURE FOR PETROL
ENGINES
With cold engine:
1) Engage the handbrake.
2) Ensure that the systems and electri-
cal devices, especially if they absorb high
quantities of energy (e.g. heated rear
windscreen), are switched off.
3) Set the gearshift lever to neutral and
fully depress the clutch without pressing
the accelerator.
4) Turn the ignition key to the AVV posi-
tion releasing it as soon as the engine starts.
Never leave the ignition
key in the MAR position
when the engine is
switched off.
5) If the engine does not start immedi-
ately, return the key to the STOPposi-
tion and repeat the operation
With hot engine:
1) Engage the handbrake.
2) Ensure that the systems and electri-
cal devices, especially if they absorb high
quantities of energy (e.g. heated rear
windscreen), are switched off.
3) Set the gearshift lever to neutral and
fully depress the clutch without pressing
the accelerator.
4) Turn the ignition key to the AVV posi-
tion releasing it as soon as the engine starts.
5) If the engine does not start immedi-
ately, return the key to the STOPposition
and repeat the procedure, slightly pressing
the accelerator pedal without pumping it.
Running the engine in
confined areas is ex-
tremely dangerous. The engine
consumes oxygen and produces
carbon monoxide which is a highly
toxic and lethal gas.
WARNING

135
IMPORTANT If it is difficult to start the
engine do not insist with extended attempts
which may damage the catalyzer but con-
tact Alfa Romeo Authorized Services.
PROCEDURE FOR DIESEL
VERSIONS
1) Engage the handbrake.
2) Set the gearshift lever to neutral and
fully depress the clutch without pressing
the accelerator.
3) Turn the ignition key to the MAR
position. the
mwarning light on the in-
strument cluster will turn on.
4) Wait for the
mwarning light to go
off, which will depend on how warm the
engine is. If the engine is very warm the
turning on of the warning light may be so
fast as to go by unobserved.
5) Turn the ignition key to AVV as
soon as the
mwarning light goes off.
Waiting too long would make the glow
plug heating work pointless.IMPORTANT The electric devices that
absorb much energy (air conditioner,
rearscreen heating, etc.) are disengaged
automatically during engine starting.
If the engine does not start at the first
attempt, move the ignition key back to
theSTOPposition before repeating s-
tarting.
If starting is difficult (with the Alfa
Romeo CODE system efficient), do not in-
sist with prolonged attempts.
Only use an auxiliary battery if it is not-
ed that the cause is due to low charge of
vehicle’s battery. Never use a battery
charger to start the engine (see ”If the
battery is flat” in the chapter “In an e-
mergency”).
WARMING THE ENGINE
– Drive off slowly, at medium revs
without accelerating abruptly.
– Do not drive at full performance for
the initial kilometres of the journey. Wait
until the engine coolant temperature is
between 50 and 60°C.
SWITCHING OFF
– Release the accelerator pedal and
wait until the engine reaches idle speed.
– Turn the ignition key to the STOP
position and switch off the engine.
IMPORTANT After a hard journey, it
is advisable to allow the engine to “get
its breath back” before switching off, run-
ning it at idle speed to allow the tempera-
ture in the engine compartment to cool
down. For versions/markets
where applicable the
warning light m flashes
for about 30 seconds after start-
ing the engine meaning that
there is a fault to the glow plug
warming system, in which case,
contact Alfa Romeo Authorized
Services.
