GETTING TO KNOW YOUR VEHICLE

reduce the cooling efficiency.
Too much cooling is not good for the
health. The inside air temperature
should only be 5 to 6 °C below the
outside air temperature.
When operating the system, make
sure the air intake, which is located in
front of the windscreen, is free of
obstructions such as leaves and snow.
Leaves collected in the air-intake
plenum may reduce air flow and plug
the plenum water drains.
Air conditioning system refrigerant
recommendations
If the air conditioning seems less
effective than usual, the cause might be
a refrigerant leak. We recommend you
to have the system inspected.
The air conditioning system in your
vehicle must be charged with the
refrigerant HFC-134a (R134a).
Use of any other refrigerant or lubricant
will cause severe damage which will
result in the need to replace your
vehicle’s entire air conditioning system.
The release of refrigerant into the
atmosphere should be prevented.
It is recommended that the refrigerant
be recovered and recycled for further
use.
During a long period of disuse
The air conditioning should be operated
for at least five minutes each week,
even in cold weather. This is to preventpoor lubrication of the compressor
internal parts and to maintain the air
conditioning in the best operating
condition.PASSENGER
COMPARTMENT AIR
CLEANER / POLLEN
FILTER
An air filter has been incorporated into
this air conditioner so that dirt and dust
are cleaned from the air.
Replace the air filter periodically as its
ability to clean the air will be reduced as
it collects pollen and dirt.
NOTE Operation in certain conditions
such as driving on a dusty road and
frequent use of the air conditioner can
lead to reduction of service life of the
filter. When you feel that the airflow is
lower than normal or when the
windscreen or windows start to fog up
easily, replace the air filter. We
recommend you to have it checked.

WARNING
67)For safety, make sure you have a clear
view through all windows.
68)Use of the recirculation position for an
extended time may cause the windows to
fog up.
IMPORTANT
22)The engine speed may increase when
the air conditioning is operating. With an
increased engine speed, an A/T vehicle will
creep to a greater degree than with a lower
engine speed. Fully depress the brake
pedal to prevent the vehicle from creeping.23)When using the air conditioning, the
idling speed may slightly increase as the air
conditioning compressor is switched on/off
automatically. While the vehicle with an
automatic transmission is stationary, fully
depress the brake pedal to prevent the
vehicle from creeping.
24)When using the mode selection dial
between the
andpositions, prevent
fogging by moving the air selection lever to
select outside air (refer to “Air selection
lever”).
25)Use of the
(recirculation) position
for extended time may cause the windows
to fog up.
26)If the outside air is dusty or otherwise
contaminated, or if high cooling
performance is desired, set air selection
lever to the
(recirculation) position
and the temperature control dial all the way
to the right. Switch to the
(outside)
position periodically to increase ventilation
so that the windows do not become
fogged up.
IMPORTANT
2)The system uses a coolant that is
compatible with the laws in force in the
countries where the vehicle is sold, R134a
(indicated on a specific plate in the engine
compartment). The use of other coolants
affects the efficiency and condition of the
system. Also the compressor coolants
used must be compatible with the
indicated coolant.

WARNING
276)To start the engine using jumper
cables from another vehicle, perform the
correct procedures according to the
instruction below. Incorrect procedures
could result in a fire or explosion or
damage to the vehicles.
277)Keep sparks, cigarettes and flames
away from the battery because the battery
may produce an explosion.
278)Do not attempt to start the engine by
pulling or pushing the vehicle. It could
damage your vehicle.
279)Check the other vehicle. It must have
a 12-volt battery. If the other system isn’t
12-volt, shorting can damage both
vehicles.
280)Use the proper cables suitable for the
battery size to prevent overheating of the
cables.
281)Check the jumper cables for damage
and corrosion before use.
282)Always wear protective eye goggles
when working near the battery.
283)Keep the battery out of the reach of
children.
284)Turn off the ignition on both vehicles
beforehand. Make sure that the cables or
your clothes cannot be caught by the fan
or drive belt. Personal injury could result.
285)If electrolyte fluid is not visible, or
appears to be frozen, Do Not Attempt
Jump Starting! A battery might rupture or
explode if the temperature is below the
freezing point or if it is not filled to the
proper level.286)Electrolyte is corrosive diluted
sulphuric acid. If electrolyte (battery acid)
comes into contact with your hands, eyes,
clothes or the painted surface of your
vehicle, it should be thoroughly flushed
with water. If electrolyte gets in your eyes,
flush them with water immediately and
thoroughly, and get prompt medical
attention.
287)Make sure that the connection is
made to the appointed position (shown in
the illustration). If the connection is made
directly to the negative (−) side of the
battery, the inflammable gases generated
from the battery might catch fire and
explode.
288)When connecting the jumper cables,
do not connect the positive (+) cable to the
negative (−) terminal. Otherwise sparks
might cause explosion of the battery.
289)Use care not to get the jumper cable
caught in the cooling fan or other rotating
part in the engine compartment.
290)Keep the engine of the vehicle giving
assistance running.
291)Battery fluid is poisonous and
corrosive: avoid contact with your skin and
eyes. The battery should be charged in a
well ventilated place, away from naked
flames or possible sources of sparks:
danger of explosion and fire.
292)Do not attempt to charge a frozen
battery: it must be thawed first, otherwise it
may explode. If freezing has occurred, the
battery should be checked by skilled
personnel to make sure that the internal
elements are not damaged and that the
body is not cracked, with the risk of leaking
poisonous and corrosive acid.
ENGINE
OVERHEATING
When the engine is overheating,will
blink. If this occurs, take the following
corrective measures:
1. Stop the vehicle in a safe place.
2. Check whether steam is coming from

4. Check the coolant level in the reserve
tank (C).
5. Add coolant to the radiator and/or
reserve tank if necessary (refer to the
“Maintenance” section).
297)
165)
6. Examine the radiator hoses for
coolant leakage and the drive belt for
looseness or damage. If there is
anything wrong with the cooling system
or drive belt, we recommend you to
have it checked and repaired.
WARNING
293)Do not open the bonnet while steam
is coming from the engine compartment. It
could cause steam or hot water to spurt
out, causing burns. Hot water could spurt
out even when there is no steam coming
out, and some parts will be very hot. Be
very careful when opening the bonnet.
294)Be careful of hot steam, which could
be blowing off the reserve tank cap.
295)Do not attempt to remove the radiator
cap while the engine is hot.
296)Be careful not to get your hands or
clothes caught in the cooling fan.
297)Make sure that the engine has cooled
down before removing the radiator cap (A),
because hot steam or boiling water
otherwise will gush from the filler port and
may scald you.
IMPORTANT
165)Do not add coolant while the engine is
hot. Suddenly adding cold coolant could
damage the engine. Wait for the engine to
cool down, then add coolant a little at a
time.
BLEEDING THE FUEL
SYSTEM
The fuel system should be bled to
remove air as described below if the
fuel supply is exhausted during travel.
Pump the hand pump (A) at the top of
the fuel filter until the hand pump
becomes stiff.
Then try again to start the engine. If the
engine does not start, repeat the
process above.

SERVICING AND MAINTENANCE

To add coolant
The cooling system is a closed system
and normally the loss of coolant should
be very slight. A noticeable drop in the
coolant level could indicate leakage. If
this occurs, we recommend you to
have the system checked as soon as
possible. If the level should drop below
the “L” (LOW) level on the reserve tank,
open the lid and add coolant.
Also, if the reserve tank is completely
empty, remove the radiator cap (B) and
add coolant until the level reaches the
filler neck.
377) 378)
Anti-freeze
The engine coolant contains an
ethylene glycol anti-corrosion agent.
Some parts of the engine are cast
aluminium alloy, and periodic changing
of the engine coolant is necessary to
prevent corrosion of these parts.
Use the recommended coolant by Fiat
or equivalent (similar high quality
ethylene glycol based non-silicate,
non-amine, nonnitrate and nonborate
coolant with long life hybrid organic
acid technology).
Fiat genuine coolant has excellent
protection against corrosion and rust
formation of all metals including
aluminium and can avoid blockages in
the radiator, heater, cylinder head,
engine block, etc.Because of the necessity of this
anti-corrosion agent, the coolant must
not be replaced with plain water even in
summer. The required concentration of
anti-freeze differs depending on the
expected ambient temperature.
Above -35 °C: 50 % concentration of
antifreeze
Below -35 °C: 60 % concentration of
antifreeze
183) 184) 185) 186) 187)
During cold weather
If the temperatures in your area drop
below freezing, there is the danger that
the coolant in the engine or radiator
could freeze and cause severe damage
to the engine and/or radiator. Add a
sufficient amount of antifreeze to the
coolant to prevent it from freezing.
The concentration should be checked
before the start of cold weather and
anti-freeze added to the system if
necessary.
WARNING
377)The used engine oil and the filter that
has been replaced contain substances that
are harmful to the environment. To change
the oil and filters, we advise you to contact
a Fiat Dealership.
378)Do not open the radiator cap (B) while
the engine is hot. The coolant system is
under pressure and any hot coolant
escaping could cause severe burns.
IMPORTANT
183)Do not use alcohol or methanol
anti-freeze or any engine coolants mixed
with alcohol or methanol anti-freeze. The
use of an improper anti-freeze can cause
corrosion of the aluminium components.
184)Concentrations exceeding 60 % will
result in a reduction of both the anti-freeze
and cooling performance thus adversely
affecting the engine.
185)Do not top up with water only.
186)PARAFLU UP anti-freeze is used in
the engine cooling system. Use fluid of the
same type as that contained in the cooling
system for any top-ups. PARAFLU UP
cannot be mixed with any other type of
fluid. If this happens, do not start the
engine under any circumstances and
contact a Fiat Dealership.
187)Do not use water to adjust the
concentration of coolant.
