WASHER FLUID
Open the washer fluid reservoir cap and
check the level of washer fluid with the
dipstick. If the level is low, replenish the
container with washer fluid.
NOTE The washer fluid container
server serves the windscreen and
headlamps (if so equipped).
During cold weather
To ensure proper operation of the
washers at low temperatures, use a
fluid containing an anti-freezing agent.
379) 380)
WARNING
379)Do not travel if the windscreen
washer reservoir is empty: using the
windscreen washer is essential for
improving visibility. Repeated operation of
the system without fluid could damage or
cause rapid deterioration of some system
components.
380)Some commercial additives for
windscreen washer fluid are flammable.
The engine compartment contains hot
components which may start a fire.
BRAKE FLUID
To check the fluid level
Check the brake fluid level in the
reservoir. The brake fluid level must be
between the “MAX” and “MIN” marks
on the reservoir.
The brake fluid level is monitored by a
float. When the brake fluid level falls
below the “MIN” mark, the brake fluid
warning lamp lights up.
The fluid level falls slightly with wear of
the brake pads, but this does not
indicate any abnormality.
If the brake fluid level falls markedly in a
short length of time, it indicates leaks
from the brake system. If this occurs,
we recommend you to have the vehicle
checked.

Fluid type
Use brake fluid conforming to DOT3 or
DOT4. The brake fluid is hygroscopic.
Too much moisture in the brake fluid will
adversely affect the brake system,
reducing the brake performance.
In addition, the brake fluid reservoir is
equipped with a special cap to prevent
the entrance of air, and this cap should
not be removed.

WARNING
381)Take care in handling brake fluid as it
is harmful to the eyes, may irritate your skin
and will damage to painted surfaces. Wipe
up spills immediately. If brake fluid gets on
your hands or in your eyes, flush
immediately with clean water. Follow up
with a doctor as necessary.
382)Some commercial windscreen washer
additives are flammable. The engine
compartment contains hot parts which
could start a fire on contact.
383)Do not travel with the windscreen
washer reservoir empty: the windscreen
washer is essential for improving visibility.
384)The cooling system is pressurised. If
necessary, only replace the plug with
another original one or the operation of the
system may be adversely affected. Do not
remove the reservoir plug when the engine
is hot: risk of burns.385)Use only the specified brake fluid. Do
not mix or add different brand of brake fluid
to prevent chemical reaction. Do not let
any petroleum-based fluid touch, mix with,
or get into the brake fluid. This will damage
the seals.
386)Clean the filler cap before removing
and close the cap securely after
maintenance.
387)Brake fluid is poisonous and highly
corrosive. In the event of accidental
contact, immediately wash the affected
parts with water and mild soap. Then rinse
thoroughly. Call a doctor immediately if
swallowed.
IMPORTANT
188)Keep the reservoir tank cap closed to
prevent the brake fluid from deteriorating
except maintenance.
189)Prevent brake fluid, which is highly
corrosive, from coming into contact with
painted parts. Should it happen,
immediately wash with water.
190)The symbol
, on the brake fluid
container indicates if a brake fluid is
synthetic or mineral-based. Use of mineral
type fluids will damage the special rubber
seals of the braking system beyond repair.
CLUTCH FLUID
(where provided)
To check the fluid level
The clutch fluid in the master cylinder
should be checked when performing
other underhood service. In addition,
the system should be checked for
leakage at the same time.
Check to make certain that the clutch
fluid level is always between the “MAX”
and “MIN” level markings on the fluid
reservoir.
A rapid fluid loss indicates a leak in the
clutch system which should be
immediately inspected by a Fiat
Dealership.
Fluid type
Brake fluid conforming to DOT 3 or
DOT 4 should be used. The reservoir
cap must be fully tightened to avoid
contamination from foreign matter or
moisture. DO NOT ALLOW

To check the fluid level
Check the fluid level in the reservoir
while the engine is idling. Check to
make certain that the power steering
fluid level is always between the “MAX”
and “MIN” level markings on the fluid
reservoir and top up the fluid, if
necessary.
WARNING
389)Prevent power steering fluid from
coming into contact with hot engine parts:
it is flammable.

BATTERY
4)
The condition of the battery is very
important for quick starting of the
engine and proper functioning of the
vehicle’s electrical system. Regular
inspection and care are especially
important in cold weather.
390) 391) 392) 393) 394) 395) 396) 397)
Checking battery electrolyte level
The electrolyte level must be between
the specified limit on the outside of the
battery. Replenish with distilled water as
necessary. The inside of the battery is
divided into several compartments;
remove the cap from each
compartment and fill to the upper mark.
Do not top up beyond the upper mark
because spillage during driving could
cause damage.Check the electrolyte level at least once
every four weeks, depending on the
operating conditions. If the battery is
not used, it will discharge by itself with
time.
Check it once every four weeks and
charge with low current as necessary.
During cold weather
The capacity of the battery is reduced
at low temperatures. This is an
inevitable result of its chemical and
physical properties. This is why a very
cold battery, particularly one that is not
fully charged will only deliver a fraction
of the starter current which is normally
available.
We recommend you to have the battery
checked before the start of cold
weather and, if necessary, have it
charged or replaced. This does not only
ensure reliable starting, but a battery
which is kept fully charged also has a
longer life.
Disconnection and connection
191) 192) 193) 194) 195) 196) 197) 198)
To disconnect the battery cable, stop
the engine, first disconnect the negative
(-) terminal and then the positive (+)
terminal. When connecting the battery,
first connect the positive (+) terminal
and then the negative (-) terminal.
NOTE Open the terminal cover (A)
before disconnecting or connecting the
positive (+) terminal of the battery.NOTE Loosen the nut (B), and then
disconnect the battery cable from the
positive (+) terminal.
Type 1
Type 2
NOTE Keep the terminals clean. After
the battery is connected, apply terminal
protection grease. To clean the
terminals, use lukewarm water.

GENERAL
MAINTENANCE
Fuel, engine coolant, oil and
exhaust gas leakage
Look under the body of your vehicle to
check for fuel, engine coolant, oil and
exhaust gas leaks.
Exterior and interior lamp operation
Operate the combination lamp switch
to check that all lamps are functioning
properly. If the lamps do not illuminate,
the probable cause is a blown fuse or
defective lamp bulb. Check the fuses
first. If there is no blown fuses, check
the lamp bulbs. For information
regarding the inspection and
replacement of the fuses and the bulbs,
refer to “Fuses” and “Replacement of
lamp bulbs”.
Meter, gauge and indicator/
warning lamps operation
Start the engine to check the operation
of all instruments, gauges, and indicator
and warning lamps. If there is anything
wrong, we recommend you to have
your vehicle inspected.
Hinges and latches lubrication
Check all latches and hinges, and, if
necessary, have them lubricated.

vehicle, it is necessary to perform
regular maintenance using the proper
procedures.
Always maintain your vehicle in
compliance with any environmental
pollution control regulations.
Carefully select the materials used for
washing, etc., to be sure that they do
not contain corrosives. If in doubt, we
recommend you to consult a specialist
for the selection of these materials.
WARNING
399)Cleaning products can be dangerous.
Always follow the instructions of the
cleaning product supplier.
IMPORTANT
200)To avoid damage, never use the
following to clean your vehicle: Petrol; Paint
Thinner; Benzine; Kerosene; Turpentine;
Naphtha; Lacquer Thinner; Carbon
Tetrachloride; Nail Polish Remover;
Acetone.
IMPORTANT
5)Detergents pollute the environment. Only
wash your vehicle in areas equipped to
collect and treat wastewater from this type
of activity.

Doing so could cause stains or damage
the finish.
Cleaning plastic parts
Use a sponge or chamois leather. If a
car wax adheres on a grey or black
rough surface of the bumper, moulding
or lamps, the surface becomes white.
In such a case, wipe it off using
lukewarm water and soft cloth or
chamois leather.
212) 213)
Chrome parts
In order to prevent spots and corrosion
of chrome parts, wash with water, dry
thoroughly, and apply a special
protective coating. This should be done
more frequently in winter.
Aluminium wheels (if so equipped)
Remove dirt using a sponge while
sprinkling water on the wheel.Use
neutral detergent on any dirt that
cannot be removed easily with
water. Rinse off the neutral
detergent after washing the
wheel.Dry the wheel thoroughly
using a chamois leather or a soft
cloth.
214) 215) 216) 217)
Window glass
The window glass can normally be
cleaned using only a sponge and water.
Glass cleaner can be used to removeoil, grease, insect carcasses, etc. After
washing the glass, wipe it dry with a
clean, dry, soft cloth. Never use a cloth
that is used for cleaning a painted
surface to clean a window. Wax from
the painted surface could get on the
glass and lower glass transparency and
visibility.
NOTE To clean the inside of the rear
window, always use a soft cloth and
wipe the window glass along the
demister heater element so as not to
cause damage.
Wiper blades
Use a soft cloth and glass cleaner to
remove grease, insect carcasses, etc.,
from the wiper blades. Replace the
wiper blades when they no longer wipe
properly.
Engine compartment
Clean the engine compartment at the
beginning and end of winter. Pay
particular attention to flanges, crevices
and peripheral parts where dust
containing road chemicals and other
corrosive materials might collect.
If salt and other chemicals are used on
the roads in your area, clean the engine
compartment at least every three
months.
Never spray or splash water on the
electrical components in the engine
compartment, as this may cause
damage.Do not bring the nearby parts, the
plastic parts and so on into contact
with sulphuric acid (battery electrolyte)
which may crack, stain or discolour
them.
If they are in contact, wipe off with soft
cloth, chamois or the like and an
aqueous solution of neutral detergent
then immediately rinse the affected
parts with plenty of water.
Versions with tonneau cover
Hand washing is recommended for the
tonneau cover; modern automatic
washing systems equipped with soft
brushes which do not apply excessive
pressure with specific products may be
used.
Never use high-pressure washing
systems. If a water jet is used, direct
away from the edges of the fabric and
the rear window to prevent water
infiltration.
Versions with stickers or wrapping
To correctly clean and wash the stickers
and/or wrapping parts, proceed as
follows:
Avoid washing with rollers and/or
brushes in washing stations. Then,
wash the vehicle, only by hand, using
pH-neutral detergents; dry it with a wet
chamois leather. Abrasive products
and/or polishes should not be used for
cleaning the vehicle.
If high pressure jets or cleaners are
used to wash the vehicle, hold at least

SERVICING AND MAINTENANCE

206)Refrain from excessively using a car
wash as its brushes may scratch the paint
surface, causing it to lose its gloss.
Scratches will be especially visible on
darker coloured vehicles.
207)Never spray or splash water on the
electrical components in the engine
compartment. Doing so could have an
adverse effect on the engine startability.
Exercise caution also when washing the
underbody; be careful not to spray water
into the engine compartment.
208)Some types of hot water washing
equipment apply high pressure and heat to
the vehicle. They may cause heat distortion
and damage to the vehicle resin parts and
may result in flooding of the vehicle interior.
Therefore maintain a good distance of
approx. 70 cm or more between the vehicle
body and the washing nozzle. Also, when
washing around the door glass, hold the
nozzle at a distance of more than 70 cm
and at right angles to the glass surface.
209)After washing the vehicle, drive the
vehicle slowly while lightly depressing the
brake pedal several times in order to dry
out the brakes. Leaving the brakes wet
could result in reduced braking
performance. Also, there is a possibility that
they could freeze up or become inoperative
due to rust, rendering the vehicle unable to
move.210)Using an automatic car wash, pay
attention to the following items, referring to
the operation manual or consulting a car
wash operator. If the following procedure is
not followed, it could result in damage to
your vehicle: 1 – the outside rear view
mirrors are retracted.2–Ifyour vehicle is
equipped with the pillar antenna, it can be
retracted. If your vehicle is equipped with
the roof antenna, it can be removed. 3 –
The wiper arms are secured in place with
tape.4–Ifyour vehicle has rain sensor
wipers, place the wiper switch lever in the
“OFF” position to deactivate the rain
sensor.
211)Waxes containing high abrasive
compounds should not be used.
212)Do not use a scrubbing brush or other
hard tools as they may damage the plastic
part surface.
213)Do not bring the plastic parts into
contact with petrol, light oil, brake fluids,
engine oils, greases, paint thinners and
sulphuric acid (battery electrolyte) which
may crack, stain or discolour the plastic
parts. If they touch the plastic parts, wipe
them off with soft cloth, chamois or the like
and an aqueous solution of neutral
detergent then immediately rinse the
affected parts with water.
214)Do not use a brush or other hard
implement on the wheels. Doing so could
scratch the wheels.
215)Do not use any cleaner that contains
an abrasive substance or is acidic or
alkaline. Doing so could cause the coating
on the wheels to peel or become
discoloured or stained.
216)Do not directly apply hot water using a
steam cleaner or by any other means.217)Contact with seawater and road
deicer can cause corrosion. Rinse off such
substances as soon as possible.
