IN AN
EMERGENCY
If after a few attempts the engine does not
start, do not insist but contact the near-
est Fiat Dealership.
IMPORTANT Do not directly connect the
negative terminals of the two batteries:
sparks could ignite the flammable gas from
the battery. If the other battery is fitted in
another car, prevent accidental contacts
between the metal parts of the two cars.
JUMP STARTING
If the battery is flat, 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:
❒Connect positive terminals (+ near
the terminal) of the two batteries with
a jump lead;
❒With a second lead, connect the neg-
ative terminal (–) of the auxiliary bat-
tery and to an earthing point
Eon the
engine or the gearbox of the car to be
started;
❒Start the engine;
❒When the engine has been started, re-
move the leads reversing the order
above.
fig. 1F0L0127m
Under no circumstances
should a battery charger be
used to start the engine: it
could damage the electronic
systems and in particular the ignition
and injection control units.
Do not carry out this proce-
dure if you lack experience; if
it is not done correctly it can cause
very intense electrical discharges. In
addition, the fluid contained in the
battery is poisonous and corrosive.
Avoid contact with skin and eyes. You
are also advised not to put naked
flames or lighted cigarettes near the
battery and not to cause sparks.

FUSE LOCATION
The vehicle’s fuses are grouped in three
central units that are located on the in-
strument dashboard, in the engine com-
partment and inside the boot (left side).
On the battery’s positive pole there is a
fourth control unit that contains large ca-
pacity fuses (MEGA-FUSE, MIDI-FUSE,
MAXI-FUSE).
To replace these fuses, con-
tact the Fiat Service Net-
work.

When towing, remember
that without the help of the
brake booster and power steering, a
greater effort is required on the ped-
al and steering wheel. Do not use
flexible cables for towing and avoid
jerks. During towing operations
make sure that fastening the joint to
the car does not damage the com-
ponents in contact with it. When
towing the car, you must comply
with the specific traffic regulations
regarding the tow ring and how to
tow on the road.
WARNING
Do not start the engine
when towing the car.
WARNING
Before starting to tow, dis-
engage the steering lock
(see paragraph “Ignition device” in
section “Dashboard and controls”).
When towing, remember that with-
out the help of the brake booster
and power steering, a greater effort
is required on the pedal and steering
wheel. Do not use flexible cables for
towing and avoid jerks. During tow-
ing operations make sure that fas-
tening the joint to the car does not
damage the components in contact
with it. When towing the car, you
must comply with the specific traffic
regulations regarding the tow ring
and how to tow on the road.
WARNING
Before fitting the hook,
clean accurately its thread-
ed seat. Before starting to tow, make
sure to have tighten the hook.

In fact, since these devices continue ab-
sorbing energy even when the ignition key
is off, they gradually run down the battery.
The total intake of these systems (facto-
ry and after-market) must be less than 0,6
mA x Ah (of the battery) as shown in the
following table:
IMPORTANT NOTES
❒As far as possible, avoid sharp brak-
ing and screech starts, etc. Be careful
not to hit the kerb, potholes or oth-
er obstacles hard. Driving for long
stretches over bumpy roads can dam-
age the tyres;
❒Periodically check that the tyres have
no cuts in the side wall, abnormal
swelling or irregular tyre wear. If any
of these occur, have the car seen to at
a Fiat Dealership;
❒Avoid overloading the car when trav-
elling: this may cause serious damage
to the wheels and tyres;
Battery Maximum
admitted
stand-by intake
70 Ah 42 mA
90 Ah (*) 54 mA
(*) Versions fitted with alarm.
WHEELS AND TYRES
Check the pressure of each tyre, includ-
ing the spare, every two weeks and before
long journeys. The pressure should be
checked with the tyre rested and cold.
For the correct tyre inflation pressure, see
“Wheels” in “Technical specifications”
section.
Incorrect pressure causes abnormal tyre
wear:
Anormal pressure: tread evenly worn.
Blow pressure: tread particularly worn
at the edges.
Chigh pressure: tread particularly worn
in the centre.
Tyres must be replaced when the tread
wears down to 1.6 mm. In any case, com-
ply with the laws in the country where the
car is being driven.

Windows
Use specific window cleaner products.
Use also clean cloths to avoid scratching
the glass or damaging the transparency.
IMPORTANT The inside of the
rearscreen should be wiped gently with a
cloth in the direction of the filaments to
avoid damaging the heating device.
Engine compartment
At the end of the winter the engine com-
partment should be carefully washed,
without directing the jet against electron-
ic control units. Contact a specialised
workshop to have this done.
IMPORTANT The car should be washed
with the engine cold and the ignition key
at OFF. After washing make sure that the
various protections (e.g. rubber caps and
various covers) have not been damaged or
removed.INTERIORS
Periodically check that water is not
trapped under the mats (due to water
dripping off shoes, umbrellas, etc.) which
could cause oxidisation of the sheet met-
al.
CLEANING SEATS AND FABRIC
AND VELVET PARTS
Use a soft brush or vacuum cleaner to re-
move dust. Velvet is cleaned better if the
brush is moistened.
Rub the seats with a sponge moistened
with a solution of water and neutral de-
tergent.
CLEANING LEATHER SEATS
Remove dried on dirt with lightly moist-
ened chamois leather or cloth without
pressing too hard.
Remove liquid or grease stains with a dry
absorbent cloth without rubbing. Then
wipe with a soft cloth or chamois leather
with water and neutral soap. Exterior plastic parts must be cleaned in
the same way as the rest of the car.
Where possible, do not park under trees;
the resinous substance many species re-
lease give the paint a dull appearance and
increase the possibility of triggering rust
processes.
IMPORTANT Bird droppings must be
washed off immediately and thoroughly as
the acid they contain is particularly ag-
gressive.
Detergents cause water pollu-
tion. Therefore the car should
be washed in areas equipped
for collecting and purifying the
liquid used in the washing process.
