CORRECT USE OF THE CAR
173
CONDITIONS OF USE
Cold starting
Short journeys and frequent cold starts do
not allow the engine to reach optimum op-
erating temperature. This results in a sig-
nificant increase in consumption levels (from
+15 to +30% on the urban cycle) and emis-
sion of harmful substances.
Traffic situations and road
conditions
Rather high consumption levels are tied to
situations with heavy traffic, for example
in queues with frequent use of the lower
gears or in cities with many traffic lights. Al-
so winding mounting roads and rough road
surfaces adversely affect consumption.
Stopping in the traffic
During prolonged stops (e.g. level cross-
ings) it is advisable to switch the engine off.
DRIVING STYLE
Starting
Do not warm the engine with the car at a
standstill or at idle or high speed: under
these conditions the engine warms up much
more slowly, increasing electrical consump-
tion and emissions. It is therefore advisable
to move off immediately, slowly, avoiding
high speeds. This way the engine will warm
faster.
Pointless manoeuvres
Avoid accelerating when waiting at traffic
lights or before switching off the engine. This
and also double declutching is absolutely
pointless on modern cars and also increase
consumption and pollution.
Gearshifting
As soon as the conditions of the traffic and
road allow, use a higher gear.
Using a low gear to obtain brilliant per-
formance increases consumption.
In the same way improper use of a high
gear increases consumption, emissions and
engine wear.Top speed
Fuel consumption considerably increases
with speed. Maintain an even as possible
speed, avoiding superfluous braking and ac-
celerating, which cost in terms of both fuel
and emissions.
Acceleration
Accelerating heavily taking the engine to
a high speed has a considerably adverse ef-
fect on consumption and emission levels;
it is wise to accelerate gradually and not ex-
ceed the maximum torque.

CORRECT USE OF THE CAR
178
Keep your speed
down when snow
chains are fitted.
Do not exceed 50 km/h. Avoid
potholes, steps and pavements and
avoid also to drive for long dis-
tances on roads not covered with
snow to prevent damaging the car
and the roadbed.
CAR INACTIVITY
If the car is to be left inactive for long pe-
riods, the following precautions should be
noted:
– House the car under cover in a dry and
possibly ventilated place.
– Engage a gear.
– Check that the handbrake is not en-
gaged.
– Clean and protect the paintwork by pro-
tective wax.
– Clean and protect the metal polished
parts with marketed products.
– Cover the rubber windscreen and
rearscreen wiper blades with talcum powder
and raise them off the glass.
– Open the windows slightly.
– Inflate the tyres to a pressure of 0.5 bars
above normal. If possible rest the tyres on
wooden planks and periodically check the
pressure.
– Do not turn on the electronic alarm sys-
tem.– Disconnect the battery negative termi-
nal from the battery and check the battery
charge. This check should be repeated
every three months during stowage.
Charge the battery if the indicator (where
provided) shows a dark colour in the central
green area.
– Do not empty the engine cooling sys-
tem.
– Cover the car with a fabric or perforat-
ed plastic cover. Do not use compact plas-
tic covers which prevent the humidity on the
surface of the car from evaporating. Snow chains cannot be
fitted to the space-saver
spare wheel. So, if a front
(drive) wheel is punctured and
chains are needed, a rear wheel
should be fitted to the front of the
car (adjust tyre pressure to the
specified value as soon as possi-
ble) and the space-saver spare
wheel should be fitted to the rear.
This way with two normal drive
wheels, snow chains can be fitted
to them to solve an emergency.
Deactivate the ASR sys-
tem when snow chains are
fitted. Press the ASR-OFF
button, button led turned on.

IN AN EMERGENCY

3) Fully depress the accelerator pedal and
keep it pressed. The
Uwarning light will
come on for eight seconds and then go off,
now release the accelerator pedal.
4) The
Uwarning light begins to flash:
after it has flashed the same number of
times as the first digit on the CODE card,
press the accelerator pedal and keep it
pressed until the
Uwarning light turns on
(for four seconds) and then goes off; now
release the accelerator pedal.
5) The
Uwarning light starts to flash: af-
ter the number of flashes corresponding to
the second digit on the CODE card, press the
accelerator pedal and keep it pressed.
6) Repeat this procedure for the remain-
ing digits on the CODE card.
7) After entering the last figure, keep the
accelerator pedal pressed. The
Uwarning
light turns on (for four seconds) and then
goes off; now release the accelerator pedal. 8) A quick flash of the
Uwarning light
(for about four seconds) confirms that the
operation has been carried out correctly.
9) Start the engine turning the ignition key
fromMARtoAV Vwithout returning the
key to the STOPposition.
Conversely, if the
Uwarning light stays
on, turn the key to STOPand repeat the
procedure starting from point 1).
IMPORTANTAfter emergency starting
it is advisable to contact Alfa Romeo Au-
thorised Services, because the emergency
procedure must be repeated each time the
engine is started.
EMERGENCY
STARTING
If it is not possible to deactivate the engine
inhibitor with the Alfa Romeo CODE system,
the
YandUwarning lights stay on and
the engine will not start. Emergency start-
ing is needed to start the engine.
IMPORTANTYou are advised to care-
fully read the entire procedure before carry-
ing it out. If a mistake is made during the
emergency procedure, the ignition key should
be turned to STOPand the operations must
be repeated from the start (point 1).
1) Read the 5-figure electronic code on the
CODE card.
2) Turn the ignition key to MAR.

STARTING
WITH AN AUXILIARY BATTERY
If the battery is flat (for battery with op-
tical hydrometer: dark colour without green
area in the centre), it is possible to start the
engine using an auxiliary battery with the
same capacity or a little higher than the flat
one.
Proceed as follows (fig. 1):
1) Remove the protective cover on the pos-
itive battery post pressing on the opening
catches (front), then connect the positive
terminals (+sign next to the terminal) of
the two batteries using a special cable.
2) Connect the end of the second jump
lead to the negative terminal (–) of the aux-
iliary battery with an earth point
Eon the
engine or gearbox of the car to be started.IMPORTANTDo not directly connect the
negative terminals of the two batteries: any
sparks may ignite the detonating gas which
could come out of the battery. If the auxil-
iary battery is installed on another car, avoid
metal parts touching accidentally between
this car and the one with the flat battery.
3) Start the engine.
4) When the engine has started, remove
the cables, reversing the sequence followed
for connection.
If after a few attempts the engine does not
start, do not insist but contact the nearest
Alfa Romeo Authorised Service.

This starting procedure
must be carried out by
qualified personnel because
incorrect operations may cause
electrical discharge of considerable
intensity. The liquid contained in
the battery is poisonous and cor-
rosive. Avoid contact with the skin
and the eyes. Keep naked flames
and lighted cigarettes away from
the battery and do not cause
sparks.
Never use a battery
charger to start the engine
as this could damage the
electronic systems of your car, par-
ticularly the ignition and fuel sup-
ply control units.

IN AN EMERGENCY

STARTING BY INERTIA
If the car is equipped with “Kit for tyre re-
pair Fix&Go“, see the instructions contained
in the following chapter.
GENERAL INSTRUCTIONS
As an alternative to the FIX & GO, the car
can be provided (upon request) with space-
saver spare wheel or standard wheel; wheel
changing and correct use of the jack call for
some precautions as listed below.
IN THE EVENT OF A PUNCTURE
Never push, tow or coast
start the car. This could
cause fuel to flow into the
catalyst damaging it irreversibly.
Remember that the en-
gine brake and power
steering are not opera-
tional until the engine is started,
therefore, much greater effort than
usual is needed on the brake ped-
al and steering wheel.
Signal the presence of the
stationary car according to
current regulations: hazard
warning lights, reflecting triangle
etc.. Any passengers should leave
the car and wait for the wheel to be
changed out of harm of the traffic.
If parked on a slope or rough sur-
face, chock the wheels with
wedges or other suitable devices
to prevent the car from rolling.
Never start the engine
with the car jacked.
When driving with a trail-
er, disconnect the trailer before
raising the car. The compact spare
wheel is specific to your car, do not
use it on other models, or use the
spare wheel of other models on
your car.
Should the type of wheels used
be changed (alloy rims instead of
steel), it is also necessary to
change the whole set of fastening
bolts with others of suitable size.
The compact spare wheel is nar-
rower than normal wheels, it
should be used only for the dis-
tance necessary to reach a service
point to have the punctured tyre
repaired and, during its use, the car
speed must not exceed 80 km/h.

CHANGING A WHEEL
Please be informed that:
– the jack mass is 2.100 kg.
– the jack requires no adjustment.
– the jack cannot be repaired. In the event
of breakage, it must be replaced by anoth-
er original one.
– no tools other than its operating crank
can be fitted to the jack.
To change a wheel, proceed as follows:– Stop the car in such a position that it is
not dangerous for the traffic, where it is pos-
sible to change the wheel safely. Where pos-
sible, park on a level, compact surface.
– Switch off the engine and engage the
handbrake.
– Engage first gear or reverse.– Use handle(A-fig.2) to remove the
stiff covering (B).
– Loosen the clamping device (A-fig. 3).
– Take out the tool container (B) and take
it near the wheel to be changed.
– Take the spare wheel (C).
– Remove the wheel cap (A-fig. 4) (on-
ly versions with steel rims)

– make sure the compressor switch A-
fig. 16is set to 0(off), start the engine
and fit plug A-fig. 17into the cigar lighter
outlet and then turn on the compressor by
setting switch A-fig. 16toI(on);
fig. 16
A0A1100b
– inflate the tyre to the correct pressure
value. Check tyre pressure on gauge B-fig.
16with compressor off to obtain precise
reading;
– if after 5 minutes it is still impossible
to reach at least 1.5 bar, disengage com-
pressor from valve and current outlet, then
move the car forth for approx. ten metres in
order to distribute the sealing fluid inside the
tyre evenly, then repeat the inflation oper-
ation;– if after this operation it is still impossi-
ble after 5 minutes to reach at least 1.8 bar,
do not start driving since the tyre is exces-
sively damaged and the quick tyre repair kit
cannot guarantee suitable sealing, contact
Alfa Romeo Authorized Services;
– once the correct tyre pressure has been
reached, start driving immediately;
fig. 17
A0A0647b
Apply the sticker in a vis-
ible position for the driver
to indicate that the tyre
has been treated with the quick
tyre repair kit. Drive carefully es-
pecially when cornering. Do not ex-
ceed 80 km/h. Avoid heavy brak-
ing and accelerating.

IN AN EMERGENCY

– after driving for about 10 minutes stop
and check again the tyre pressure; pull up
the handbrake;
fig. 18
A0A1101b
fig. 19
A0A1102b
If the pressure falls below
1.8 bars, do not drive any
further: the quick tyre re-
pair kit Fix & Go automatic cannot
guarantee proper hold because the
tyre is too much damaged. Contact
Alfa Romeo Authorized Services.
– drive with the utmost care to the near-
est Alfa Romeo Authorized Service.
It is of vital importance to
communicate that the tyre
has been repaired using the
quick tyre repair kit. Hand the in-
struction brochure to the personnel
charged with treating the tyre re-
paired with the kit.FOR CHECKING AND
RESTORING PRESSURE ONLY
The compressor can be also used just for
restoring pressure. Disconnect the quick con-
nectionA-fig. 18and connect it directly
to the tyre valve fig. 19; in this way the
cylinder is not connected to compressor and
the sealing fluid will not flow into the tyre.
– if at least 1.8 bar pressure is read, re-
store proper pressure (with engine running
and handbrake on) and restart;

– Fit a new bulb, making the tab of the
metal part coincide with the one on the lamp
unit, then hook the bulb holder catch (B).
– Re-connect the electric connector (A).
– Refit the protective cover correctly.Fog lights(fig. 24)
IMPORTANTWhen needing to change
the left bulb, the side trim next to the light
itself needs to be removed to facilitate ac-
cess to the engine compartment.
To change the bulb, proceed as follows:
– Remove the protective cover turning
counter-clockwise.
– Disconnect the electric connector (A).
– Release the bulb catch (B).
– Remove the bulb and replace it.
fig. 24
A0A0161b
After replacement, refit
the covers correctly check-
ing that they are properly
secured.
IMPORTANTA slight layer of steam
(fogging) can appear on the inside surface
of the beam transparent cover: this is not
a defect. The presence of condensate traces
in beams is a natural phenomenon, due to
a low temperature and to the degree of hu-
midity in the air. These traces will disappear
when the beams are turned on. Drops of wa-
ter inside the headlight indicate instead wa-
ter infiltration: contact Alfa Romeo Autho-
rised Services.
