If the warning light ¬does not turn on when the key
is turned to MAR, or if it stays on when travelling (to-
gether with the message on the display on some ver-
sions), there could be a failure in the restraint systems. If
this is the case, the air bags or pretensioners may not be de-
ployed in the event of an accident or, less likely, they may
be deployed accidentally. Do not drive the car and contact
a Alfa Romeo Authorised Service Provider to have the sys-
tem checked immediately.
The expiry dates of the pyrotechnic charge and
clock contact are shown in the plate installed in-
side the glove compartment. Go to an Alfa Romeo
Authorised Service Provider when the time to have them
replaced approaches.
Do not travel with objects on your lap, in front of
your chest, or between your lips (e.g. pipes, pen-
cils, etc.): you may be seriously injured in the event
of a crash with air bag deployment.
If someone tries to steal or damage your car, and
in the event of floods, have the air bag system
checked by an Alfa Romeo Authorised Service
Provider.
With the ignition key inserted and turned to MAR,
the air bags can be deployed also with the car at
a standstill, if it is hit by another vehicle even if the
engine is off. For this reason, children must never sit on
the front seat, even if the car is not moving. Remember
that no safety device (airbag or pretensioner) will be de-
ployed in a crash if the key is inserted and turned to the
STOP position. Failure to deploy in such cases must not
be considered a sign of malfunction.
When the ignition key is turned to MAR, the “
warning light turns on (front airbag on passenger’s
side enabled) and will blinks for a few seconds as
a reminder that the passenger airbag will be deployed
in the event of a crash and then go off.
The front air bags are deployed in the event of
more severe collisions than those required for de-
ploying the pretensioners.
For collisions in the range between the two thresholds, it
is normal for only the pretensioners to be activated.

STARTING AND DRIVING
STARTING PROCEDURE FOR DIESEL VERSIONS
Proceed as follows:
❍engage the handbrake and place the gearbox in neutral;
❍turn the ignition key to the MAR position: warning lights m
andYon the instrument panel will light up;
❍wait for the warning lights to go out;
❍press the clutch pedal down to the floor without touching the
accelerator;
❍turn the ignition key to AVV as soon as warning light mgoes
out. Waiting too long will waste the heating work carried out
by the glow plugs. Release the key as soon as the engine starts.
If warning light mblinks for approximately 1
minute after starting or during prolonged crank-
ing, this indicates a fault in the glow plug pre-heat-
ing system. Use the car normally if the engine starts and
go to Alfa Romeo Authorized Services as soon as possible.
It is dangerous to have the engine running indoors.
The engine takes in oxygen and discharges carbon
dioxide, carbon monoxide and other toxic gases.
STARTING THE ENGINE
STARTING PROCEDURE FOR PETROL VERSIONS
Proceed as follows:
❍engage the handbrake and place the gearbox in neutral;
❍press the clutch pedal down to the floor without touching the
accelerator;
❍turn the ignition key to AVV and let it go the moment the en-
gine starts.
IMPORTANT
❍If the engine does not start on the first attempt, turn the igni-
tion key to STOP before repeating the operation.
❍If, when the ignition key is at MAR, the instrument panel warn-
ing light
Yremains on together with warning light U, turn
the key to STOP and then back to MAR; if the warning light
remains on, try with the other keys provided with the car. If
you are still unable to start the engine contact Alfa Romeo Au-
thorized Services.
❍Never leave the ignition key on MAR when the engine is off.

It is advisable not to demand maximum perfor-
mance from your car (e.g. excessive acceleration,
long distances at top rpm, excessively intense brak-
ing, etc.) when it is first used.
Remember that the brake servo and electro-
mechanical power steering are not operational un-
til the engine has been started, therefore much
more effort than usual is required on the brake pedal and
steering wheel.
Never jump start the engine by pushing, towing or
driving downhill. These manoeuvres may damage
the catalytic converter.
When the engine is switched off never leave the
key in the MAR position to prevent useless cur-
rent absorption from draining the battery.
HOW TO WARM UP THE ENGINE
AFTER IT HAS JUST STARTED
Proceed as follows:
❍drive off slowly, letting the engine turn at medium speed. Do
not accelerate abruptly;
❍do not demand maximum performance for the first few kilo-
metres. Wait until the engine coolant temperature indicator
starts moving.
STOPPING THE ENGINE
Turn the ignition key to STOP while the engine is idling.
IMPORTANT After a taxing drive, before turning the engine off you
should allow it to idle to allow the temperature in the engine com-
partment to fall.
A quick burst on the accelerator before turning off
the engine serves absolutely no practical purpose;
it wastes fuel and is especially damaging to tur-
bocharged engines.

IMPORTANT Carry out these manoeuvres with the brake pedal pressed.
IMPORTANT For cars equipped with a front armrest, lift this up to
ensure that it does not interfere with the action of the handbrake.
fig. 110A0K0073m
The car should be locked after a few notches: if this
is not so, contact Alfa Romeo Authorized Services to
have the handbrake adjusted.
PARKING THE CAR
Switch off the engine and pull up the handbrake. Engage a gear
(1stif the car is facing uphill or reverse if it is facing downhill) and
leave the wheels steered to one side.
If the car is parked on a steep slope block the wheels with a wedge
or stone. Always remove the ignition key when leaving the car.
HANDBRAKE fig. 110
To engage the handbrake pull lever A upwards until the car is se-
cured. To disengage slightly raise lever A, press and hold down but-
ton B and lower the lever.

DRIVING STYLE
Starting
Do not warm up the engine at low or high revs when the car is
stationary; this causes the engine to warm up more slowly, there-
by increasing fuel consumption and emissions. It is advisable to set
off immediately and slowly, avoiding high revs: this allows the
engine to warm up more quickly.
Unnecessar y actions
Avoid revving up when starting at traffic lights or before stopping
the engine. The latter action, like double-declutching, is unneces-
sary and causes increased fuel consumption and pollution.
Gear selection
Use a high gear when traffic and road conditions allow. Using a
low gear for faster acceleration will increase fuel consumption. In
the same way, improper use of a high gear increases fuel con-
sumption, emissions and engine wear.
Top speed
Fuel consumption considerably increases as speed increases. Keep
your speed as even as possible, avoiding unnecessary braking
and acceleration which cause excessive fuel consumption and in-
creased emissions.
Acceleration
Accelerating violently severely affects consumption and emissions:
acceleration should be gradual and should not exceed the maxi-
mum torque.
CONDITIONS OF USE
Cold starting
Short distances and frequent cold start-ups prevent the engine from
reaching its optimum running temperature. Consequently, both con-
sumption (from +15 to +30% on the urban cycle) and emissions
will increase.
Traffic and road conditions
High fuel consumption is caused by heavy traffic, for instance when
travelling in a queue with frequent use of low gears or in cities with
many traffic lights. Mountain roads and uneven surfaces also have
a negative effect on consumption.
Traffic hold-ups
During prolonged hold-ups (level crossings) the engine should be
switched off.

Keep your speed down when snow chains are fit-
ted - do not exceed 50 km/h. Avoid potholes, steps
and pavements and also avoid driving for long dis-
tances on roads not covered with snow to avoid damag-
ing the car and the road surface.
SNOW CHAINS
The use of snow chains should be in compliance with local regu-
lations. Snow chains may be fitted only to the front wheel tyres
(drive wheels).
Check the tension of the chains after the first few metres have been
driven.
Use reduced bulk snow chains:
– All versions: for 195/55 R16”, 205/55 R16” and 225/45
R17” size tyres use low-clearance snow chains with a maximum
protrusion beyond the tyre profile of 9 mm.
IMPORTANT The space-saver wheel cannot be fitted with snow
chains. If a front (drive) wheel is punctured and snow chains must
be used, you must remove a normal wheel from the rear and re-
place this one with the space-saver wheel. In this way, with two
normal drive wheels, it is possible to use snow chains.
STORING THE CAR
If the car is to be left inactive for longer than a month, the following
precautions should be noted:
❍park the car in a dry, covered and, if possible, ventilated area;
engage a gear and check that the handbrake is not engaged;
❍disconnect the negative battery terminal and check battery
charge. Repeat this check once every three months during stor-
age;
❍clean and protect painted areas using protective wax;
❍clean and protect the shiny metal areas using special com-
mercially-available products;
❍sprinkle talcum powder on the rubber windscreen and rear win-
dow wiper blades and lift them off the glass;
❍slightly open the windows;
❍cover the car with a fabric or perforated plastic sheet. Do not
use compact plastic sheets which do not allow humidity to evap-
orate from the surface of the car.
❍inflate tyres to a pressure of +0.5 bar above the normal spec-
ified pressure and check the pressure at regular intervals;
❍if you have not disconnected the battery, check the battery
charge every thirty days;
❍do not drain the engine cooling system.

IN AN EMERGENCY
In an emergency we recommend that you call the freephone number found in the Warranty Booklet.
You can also consult www.alfaromeo.com to find your nearest Alfa Romeo Authorized Services.
STARTING THE ENGINE
If the Ywarning light in the instrument panel remains on con-
stantly, contact Alfa Romeo Authorized Services immediately.
JUMP STARTING
If the battery is flat, the engine may be started using an auxiliary
battery with the same capacity or a little higher than the flat one.
For engine starting follow the procedure below, fig. 112:
❍connect the positive terminal (+) of the booster battery only
with the point indicated on the vehicle battery (writing OK
figure 112) and nowhere else;
❍with a second lead, connect the negative terminal (–) of the
auxiliary battery to an earthing point
Eon the engine or the
gearbox of the car to be started;
❍when the engine has been started, follow the sequence above
in reverse order to remove the leads.
Contact an Alfa Romeo Authorised Service Provider if you cannot
start the engine after several attempts.
IMPORTANT Never connect the negative terminals of the two bat-
teries directly! If the auxiliary battery is installed on another car,
prevent accidental contact between metallic parts of the two cars.

The space-saver spare wheel is vehicle-specific:
do not use it on vehicles of other model and do not
use space-saver spare wheels from other models
on your car. The space-saver spare wheel must only be
used in an emergency. Never use it longer than strictly
necessary and never exceed 80 km/h. On the space-saver
spare wheel there is a label, summarizing the main warn-
ings about the space-saver spare wheel usage restrictions.
Never remove or cover the label. Never apply any hub
cap to the space-saver spare wheel.
CHANGING A TYRE
GENERAL INSTRUCTIONS
The car is equipped with an “Automatic Fix&Go Kit“: see “Auto-
matic Fix&Go Kit” for how to use this device.
Alternatively to the “Automatic Fix&Go Kit” the car may be
equipped with a space-saver spare wheel: see the instructions on
the following pages for changing the tyre.
Use your hazard lights, warning triangle, etc. to
show that your car is stationary in compliance with
regulations. Passengers should get out of the car,
particularly if it is heavily loaded, and wait for the wheel
to be changed away from the traffic. In the event of a
wheel change on a slope or on unsurfaced roads, chock
the wheels.
BUMP STARTING
Never start the engine by pushing, towing or driving downhill.
Never use a fast battery-charger to start the en-
gine as this could damage the electronic systems
of your car, particularly the ignition and fuel sup-
ply control units.
