ENGINE OIL
168)
86)
Check the oil level a few minutes (about
5) after the engine has stopped, with
the vehicle parked on level ground.
Check that the oil level is between the
MIN and MAX references on the
dipstick A.
If the oil level is near or under the MIN
reference, add oil through the filler B
until it reaches the MAX reference.
Take out the engine oil dipstick A, clean
it with a lint-free cloth and reinsert it.
Extract it again and check that the level
is between the MIN and MAX marks on
the dipstick.
Engine oil consumption
87)
3)
The maximum engine oil consumption
is usually 400 grams every 1,000 km.
When the vehicle is new, the engine
needs to be run in; therefore the engine
oil consumption can only be considered
stabilised after the first 5,000 -
6,000 km.
IMPORTANT After adding or changing
the oil, let the engine turn over for a few
seconds and wait a few minutes after
turning it off before you check the level.
ENGINE COOLANT

If the level is too low, unscrew the cap
of reservoir C and add the fluid
described in the "Technical
Specifications" chapter.

170) 171)
If the level is too low, lift reservoir cap D
and add the fluid described in the
chapter "Technical Specifications".
IMPORTANT The headlight washer
system (present) will not operate when
the fluid level is low, even though the
windscreen/rear window washer
continues to operate.BRAKE FLUID
172) 173)
89)
Check that the fluid is at the max. level.
If the fluid level in the reservoir is too
low, undo reservoir cap E and add the
fluid described in the chapter "Technical
Specifications".
IMPORTANT Carefully clean the cap of
the reservoir and the surrounding
surface. Take great care to ensure that
impurities do not enter the reservoir
when the cap is opened.
For topping-up, always use a funnel
with integrated filter with mesh equal to
or lower than 0.12 mm.
IMPORTANT Brake fluid is hygroscopic
(i.e. it absorbs moisture). For this
reason, if the vehicle is mainly used in
areas with a high degree of
atmospheric humidity, the fluid should
be replaced at more frequent intervals
than specified in the "Scheduled
Servicing Plan".

A periodic check carried out at a Fiat
Dealership is, however, necessary to
check efficiency.
Replacing the battery
If necessary, replace the battery with
another original battery with the same
specifications. Follow the battery
Manufacturer’s instructions for
maintenance.
USEFUL ADVICE FOR
EXTENDING THE LIFE OF
YOUR BATTERY
Useful advice for extending the life
of your battery
To avoid draining your battery and
make it last longer, observe the
following instructions:
when you park the vehicle, ensure
that the doors, tailgate and bonnet are
closed properly, to prevent any lights
from remaining on inside the passenger
compartment;
switch off all roof lights inside the
vehicle: the vehicle is however
equipped with a system which switches
all interior lights off automatically;
do not keep accessories (e.g. radio,
hazard warning lights, etc.) switched on
for a long time when the engine is not
running;
before performing any operation on
the electrical system, disconnect the
negative battery cable.
If, after purchasing the vehicle, you wish
to install electrical accessories which
require permanent electrical supply (e.g.
alarm, etc.) or accessories which
influence the electrical supply
requirements, contact a Fiat Dealership,
whose qualified staff will evaluate the
overall electrical consumption.
91)
IMPORTANT After the battery is
disconnected, the steering must be
initialised. The
warning light on the
instrument panel (or symbol on the
display) switches on to indicate this. To
carry out this procedure, simply turn the
steering wheel all the way from one end
to the other or drive in a straight line for
about a hundred metres.
IMPORTANT If the charge level remains
under 50% for a long time, the battery
is damaged by sulphation, reducing its
capacity and efficiency at start-up. The
battery is also more prone to the risk of
freezing (at temperatures of -10°C).
Refer to the "Vehicle inactivity"
paragraph in "Starting and driving"
chapter if the vehicle is left parked for a
long time.
WARNING
166) Never smoke while working in the
engine compartment: gas and inflammable
vapours may be present, with the risk of
fire.
167) Be very careful when working in the
engine compartment when the engine is
hot: you may get burned.
168) If the engine oil is being topped up,
wait for the engine to cool down before
loosening the filler cap, particularly for
vehicles with aluminium cap (where
provided). WARNING: risk of burns!
195

connect the positive cable (+) of the
battery charger to the positive battery
terminal E and the negative cable (–) to
sensor terminal D as shown;
turn on the battery charger. At the
end of the charging process, switch the
battery charger off;
after having disconnected the
charging device, reconnect connector A
to the sensor C as shown.

WINDSCREEN / REAR
WINDOW WIPERS
Raising the windscreen wipers
If you need to lift the windscreen wiper
blades (e.g. in case of snow or when
they need to be replaced), you need to
activate the "Service Position" function
(see paragraph "Windscreen/Rear
window wiper" in the "Knowing your
vehicle" chapter).
To lower the blades, set the ignition
device to MAR-ON.
IMPORTANT Place the blades back in
contact with the windscreen before
activating the windscreen wiper again
and/or setting the ignition device to
MAR-ON.
Replacing the windscreen wiper
blades
Proceed as follows:
raise the wiper arm, press button A
fig. 171 of the attachment spring and
remove the blade from the arm;
fit the new blade, inserting the tab in
the dedicated housing in the arm and
checking that it is locked;
lower the wiper arm on the
windscreen.
IMPORTANT Do not operate the
windscreen wiper with the blades lifted
from the windscreen.
Replacing the rear window wiper
blade
Proceed as follows:
widen the two tabs as shown by the
arrows and rotate cover A
fig. 172 outwards;
undo nut B and remove arm C from
the central pin;
correctly align the new arm;
fully tighten nut B and then refit
cover A.
IMPORTANT Do not operate the rear
window wiper with the blade lifted from
the rear window.
NOZZLES
Windscreen washer
The window washer nozzles are fixed. If
there is no jet of fluid, firstly check that
there is fluid in the reservoir (see
paragraph “Engine compartment” in
this chapter). Then check that the
nozzle holes are not clogged; use a
needle to unblock them if necessary.
IMPORTANT In versions with sun roof,
make sure that the roof is closed before
operating the windscreen washer
nozzles.
Rear window washer
The rear window washer nozzle is fixed.
The jet nozzle is located at the side of

Engine compartment
At the end of every winter, wash the
engine compartment thoroughly, taking
care not to aim the jet of water directly
at the electronic control units or at the
windscreen/rear window wiper motors.
Have this operation performed at a
specialised workshop.
IMPORTANT The washing should take
place with the engine cold and the
ignition device in the STOP position.
After the washing operation, make sure
that the various protections (e.g. rubber
caps and guards) have not been
removed or damaged.
IMPORTANT
101)In order to preserve the aesthetic
appearance of the paint abrasive products
and/or polishes should not be used for
cleaning the vehicle. 102)
Avoid washing with rollers and/or
brushes in washing stations. Wash the
vehicle only by hand using neutral pH
detergents; dry it with a wet chamois
leather. Abrasive products and/or polishes
should not be used for cleaning the car.
Bird droppings must be washed off
immediately and thoroughly as the acid
they contain is particularly aggressive.
Avoid (if at all possible) parking the vehicle
under trees; remove vegetable resins
immediately as, when dried, it may only be
possible to remove them with abrasive
products and/or polishes, which is highly
inadvisable as they could alter the typical
opaqueness of the paint. Do not use pure
windscreen washer fluid for cleaning the
front windscreen and rear window; dilute it
min. 50% with water. Only use pure screen
washer fluid when strictly necessary due to
outside temperature conditions.IMPORTANT
6) Detergents pollute the environment. Only
wash your vehicle in areas equipped to
collect and treat wastewater from this type
of activity.
INTERIORS
186) 187) 188)
Periodically check the cleanliness of the
interior, beneath the mats, which could
cause oxidation of the sheet metal.
SEATS AND FABRIC
PARTS
Remove dust with a soft brush or a
vacuum cleaner. It is advisable to use a
moist brush on velvet upholstery. Rub
the seats with a sponge moistened with
a solution of water and mild soap.
LEATHER SEATS(where provided)
Remove the dry dirt with a slightly
damp buckskin or cloth, without
exercising too much pressure.
Remove any liquid or grease stains
using an absorbent dry cloth, without
rubbing. Then clean with a soft cloth or
buckskin cloth dampened with water
and mild soap. If the stain persists, use
specific products and observe the
instructions carefully.
IMPORTANT Never use alcohol. Make
sure that the cleaning products used
contain no alcohol or alcohol
derivatives, even in small quantities.
