STORING THE CAR
The following precautions should be
taken if the car will not be used for
several months:
– Park the car in covered, dry and if
possible well-ventilated premises.
– Engage a gear.
– Make sure the handbrake is not
engaged.
– Remove the cables from the bat-
tery terminals (first remove the cable
to the negative terminal), and check
the battery charge. If the car is to be
stored for long periods the charge of
the battery should be checked every
month and recharged if it falls below
12.5V.– Clean and protect the shiny metal
parts using special compounds readily
available.
– Sprinkle talcum powder on the
rubber windscreen and rear window
wiper blades and lift them off the glass.
– Open the windows slightly.– Cover the car with a cloth or per-
forated plastic sheet. Do not use
sheets of non-perforated plastic as
they do not allow moisture on the car
body to evaporate.
– Inflate the tyres to + 0.5 bar above
the normal specified pressure and
check it at intervals.
– Do not drain the engine cooling
system.

EMERGENCY
START-UP
If the Fiat CODE cannot deactivate
the engine immobilising system, the
¢and
Uwarning lights stay on and
the engine will not start. Follow the
emergency start-up procedure to
start the engine.
Read the whole procedure care-
fully before trying to carry it out.
If you make a mistake, you must turn
the ignition key back to STOPand
repeat the whole operation from the
beginning (step 1).
1)Read the 5-figure electronic code
given on the CODE card.
2)Turn the ignition key to MAR.3)Press and hold down the acceler-
ator pedal. The injection system warn-
ing light
Uwill come on for about 8
seconds, and then go out. At this
point release the accelerator pedal
and get ready to count the flashes of
warning light
U.
4) Count the number of flashes that
corresponds to the first figure of the
code on the CODE card, then press
the accelerator pedal and keep it there
until the
Uwarning light comes on
for four seconds and then goes out;
release the accelerator pedal.
5) The
Uwarning light will start
flashing again: after it has flashed the
number of times that corresponds to
the second figure on the CODE card,
press the accelerator pedal to the
floor and keep it there.
6) Do the same for the remaining
figures on the CODE card. 7) Once the final figure has been en-
tered, keep the accelerator pedal
pressed. The injection warning light
Uwill light up for four seconds and
then go out; release the accelerator
pedal.
8)The
Uwarning light will flash
rapidly for about 4 seconds to indicate
that the operation has been com-
pleted correctly.
9) Start the engine by turning the ig-
nition key from MARto AVV.
If, however, the
Uwarning light
stays on, turn the ignition key to
STOPand repeat the procedure
from step 1.
IMPORTANTAfter an emergency
start, you should contact a Fiat Deal-
ership, otherwise you will have to re-
peat the procedure described each
time you want to start the engine.

88IN AN EMERGENCY
JUMP STARTING
If the battery is flat, you can use an-
other battery to start the engine. Its
capacity must be the same or slightly
greater than the flat battery (see the
chapter
TECHNICAL SPECIFICATIONS).
Proceed as follows:
1)connect positive terminals Aand
B-fig. 1of the two batteries with a
jump lead.
2)With a second lead, connect the
negative terminal Cof the auxiliary
battery to an earth point Dof the car.IMPORTANTDo not directly
connect the two negative terminals:
sparks could ignite the flammable gas
from the battery.
If the auxiliary battery is fitted in an-
other vehicle, prevent accidental con-
tact of metallic parts.
3)Start the engine.
4)When the engine has been
started, remove the leads in the re-
verse order: D, C, Band finally A.
If the engine fails to start after a few
attempts, do not keep on but have the
car seen to at a Fiat Dealership. Do not carry out this
procedure if you lack ex-
perience; if it is not done
correctly it can cause very in-
tense electrical discharges. In ad-
dition, the fluid contained in the
battery is poisonous and corro-
sive. Avoid contact with skin and
eyes.
You are also advised not to put
naked flames or lighted ciga-
rettes near the battery and not
to cause sparks.
fig. 1
P4Q00087
Under no circumstances
should a battery charger
be used to start the en-
gine: it could damage the elec-
tronic systems and in particular
the ignition and injection control
units.

89IN AN EMERGENCY
BUMP STARTING IF A TYRE IS
PUNCTURED
General instructions
Observe the instructions on this and
the following pages to use the jack and
space-saver spare wheel correctly. The space-saver spare
wheel is vehicle-specific.
Never use the wheel on
other models. Never fit other
model spare wheels on your car.
If you change the type of wheels
(alloy rims instead of steel rims)
you will have to change the en-
tire set of fastening bolts with an-
other set of suitably sized bolts.
Only use the spare-saver wheel
for emergencies. Do not exceed
80 km/h with the spare wheel fit-
ted. When driving with a space-
saver spare wheel fitted, the dri-
ving performance of your car
may change. Avoid accelerating
or braking suddenly, steering
abruptly or fast cornering.
A space-saver spare wheel has a
maximum life of 3,000 km after
which is must be replaced with a
wheel of the same type. Do not bump start by
pushing, towing or coast-
ing downhill. This way of
starting could cause a rush of fuel
into the catalytic exhaust pipe
and damage it beyond repair.
Remember that until
the engine has started
the brake booster and
power steering systems will not
work and a greater effort will
therefore be required to press
the brake pedal or turn the
steering wheel.
Alert other drivers that
the car is stationary in
compliance with local
regulations: hazard warning
lights, warning triangle etc.
Any passengers on board should
leave the car, especially if it is
heavily laden. Passengers should
stay away from oncoming traffic
while the wheel is being changed.
If the wheel is being changed on
a steep or badly surfaced road,
place wedges or other suitable
material under the wheels to
stop the car.

93IN AN EMERGENCY
IMPORTANTFor cars equipped
with optional alloy wheels, a specific
spare wheel is required which differs
from that used on cars equipped with
steel rims. When fitting alloy rims to
replace steel rims at a later date, the
four original wheel bolts should be
changed with a new set of adequately
sized bolts and a specific spare wheel.
It is advised to keep the bolts and
the spare wheel, which would become
necessary if you should decide to re-
turn to the original type of wheels. IF A BULB BURNS
OUT Only touch the metal
part when handling halo-
gen bulbs. If the transpar-
ent bulb is touched it reduces the
intensity of the light emitted and
can also reduce the life of the
bulb. If you touch the bulb acci-
dentally, rub it with a cloth
moistened with alcohol and leave
it to dry. Modifications or repairs
to the electrical system
carried out incorrectly
and without bearing the features
of the system in mind can cause
malfunctions with the risk of fire.
You should, where pos-
sible, have your bulbs
changed at a Fiat Dealer-
ship. Correct operation of the ex-
ternal light beams are essential
for safe driving and compliance
with legal requirements. Halogen bulbs contain
pressurised gas which, if
broken, may cause small
fragments of glass to be pro-
jected outwards.

94IN AN EMERGENCY
GENERAL INSTRUCTIONS
When a light is not working, check
that it has not fused before changing
the bulb.
For location of fuses, refer to
IF A
FUSE BLOWS
in this chapter.
Before replacing a bulb that does not
work, check that the contacts are not
oxidised.
Burnt-out bulbs must be replaced
with ones of the same type.
Always check the height of the head-
light beam after changing a bulb.

P4Q00160
IMPORTANTOn the inside sur-
face of the headlight there could ap-
pear a slight coat of fogging; this does
not show a defect, since it is a natural
occurrence due to low temperature
and to the degree of humidity in the
air; it will soon disappear as soon as
the lights are turned on. The presence
of drops inside the headlight shows
water seepage, refer to the Fiat
Dealership.

95IN AN EMERGENCY
TYPES OF BULBS fig. 11
Several types of bulbs are installed in
the car:
A. Glass bulbs Snapped into posi-
tion. Pull to remove.
B. Bayonet connection bulbs Re-
move from the bulb holder by press-
ing the bulb and rotating it anti-clock-
wise.
C. Cylindrical bulbs Remove by
pulling away from terminals.
D. Double filament halogen
bulbs To remove the bulb release the
clip holding the bulb in place.
