(*) Regardless of the distance covered, the timing belt must be changed every four years for particularly demanding use (cold climates,
city driving, long periods of idling) or at least every five years in all other cases.
(**) The engine oil and filter should be replaced according to their effective state, displayed by a message or warning light on the instru-
ment panel, or at least every 24 months.
If the vehicle is driven mainly in towns, change engine oil and filter every 12 months.

INDEXHEAVY USAGE OF THE VEHICLE
If the vehicle is primarily used in one of the following
particularly onerous conditions:
❒ towing trailers;
❒ dusty roads;
❒ short, repeated journeys (less than 7-8 km) at sub-ze-
ro temperatures;
❒ frequently idling engine or long-distance, low-speed
driving (e.g. door-to-door deliveries) or lengthy inac-
tivity;
❒ driving in towns and cities;
you should perform the following inspections more fre-
quently than shown on the Scheduled Servicing Plan:
❒ check front disc brake pad conditions and wear;
❒ check cleanliness of bonnet and boot locks, and clean-
liness and lubrication of linkages;
❒ visually inspect the conditions of: engine, gearbox,
transmission, pipes and tubes (exhaust – fuel – brakes),
rubber parts (boots, sleeves, bushes, etc.);
❒ check battery charge and fluid level (electrolite) (check
to be carried out only by specialists or at a Fiat Deal-
ership – see the “Battery” paragraph in this section);
❒ visually inspect the condition of the accessory drive
belts;
❒ check pollen filter and replace, if required;
❒ check and, if necessary, replace air filter.
REGULAR CHECKS
Every 1,000 km or before long journeys, check and, if nec-
essary, top up:
❒ engine coolant fluid level;
❒ brake fluid level;
❒ windscreen washer level;
❒ tyre pressure and conditions.
❒ operation of lighting system (headlights, direction in-
dicators, hazard lights, etc.);
❒ operation of windscreen washer/wipers system and
positioning/wear of windscreen/rear window wiper
blades (for versions/markets where provided);
Check and top up, if required, the engine oil level every
3,000 km.
You are recommended to use
PETRONAS LUBRI-
CANTS
products, which have been designed and pro-
duced specifically for Fiat vehicles (see “Capacities” table
in the “Technical specifications” section).

ENGINE OIL fig. 180-181-182-183-184
Check the oil level a few minutes after stopping the en-
gine (about 5 minutes) with the vehicle parked on level
ground.
The oil level should be between the MIN and MAX marks
on the dipstick B.
The gap between the MIN and MAX marks corresponds
to about one litre of oil.
If the oil level is near or under the MIN line, add oil through
the filler A until it reaches the MAX line.
The oil level should never exceed the MAX line.
Engine oil consumption
The maximum engine oil consumption is usually 400 grams
every 1,000 km.
The engine needs to run in when the vehicle is new, and
therefore the engine oil consumption can only be consid-
ered stabilised after the first 5,000 – 6,000 km.
IMPORTANT Oil consumption depends on driving style
and conditions of use of the vehicle.
IMPORTANT After adding or changing the oil, let the en-
gine turn over for a few seconds and wait a few minutes
after turning it off before you check the level.

Be very careful working in the engine com-
partment when the engine is hot: you may
get burned. Remember that the fan may start up
if the engine is hot: this could injure you. Make
sure that scarves, ties and other items of loose-
fitting clothing do not get caught up in moving
components.
WARNING
Do not add oil with different characteris-
tics from those of the existing engine oil.
The used engine oil and the replaced oil fil-
ter contain substances that are harmful to
the environment. It is advisable to have oil
and filters changed by a Fiat Dealership, where they
will be disposed of properly and in accordance with
the law.

INDEXWINDSCREEN/REAR WINDOW WASHER
FLUID fig. 180-181-182-183-184
To add fluid, remove cap D by manoeuvring the special
tab.
Pour in a mixture of water and TUTELA PROFESSION-
AL SC35 liquid, in the following concentrations:
30% TUTELA PROFESSIONAL SC35 and 70% water in
summer.
50% TUTELA PROFESSIONAL SC35 and 50% water in
winter.
At temperatures below –20°C, use undiluted TUTELA
PROFESSIONAL SC35 fluid.
Check level through the reservoir.
Close cap D by pressing on the centre section. ENGINE COOLANT fig. 180-181-182-183-184
The coolant level should be checked when the engine is
cold and should be between the MIN and MAX lines on
the reservoir. If the level is low, slowly pour into the reser-
voir filler neck Ca mixture of 50% distilled water and
50% PARAFLU UP (made by PETRONAS LUBRI-
CANTS) until the level approaches MAX.
The mixture of 50% PARAFLU UP and 50% distilled wa-
ter protects against freezing down to temperatures of
–35°C. For particularly harsh climate conditions, we rec-
ommended using a mixture of 60% PARAFLU UP and 40%
distilled water.
PARAFLU UP anti-freeze is used in the en-
gine cooling system. Use the same fluid as in
the cooling system when topping up.
PARAFLU UP may not be mixed with any other type
of fluid. If this happens, do not start the engine; con-
tact a Fiat Dealership.
The cooling system is pressurised. If the cap
needs replacing, do so with another origi-
nal or the effectiveness of the system may be com-
promised. Do not remove the cap from the reser-
voir when the engine is hot: you may get burned.
WARNING
Do not travel if the windscreen washer
reservoir is empty: using the windscreen
washer is essential for improving visibility.
Some commercial windscreen washer additives
are flammable. The engine compartment contains
hot parts which could cause a fire if they come
into contact with these additives.

INDEXPOWER STEERING FLUID
fig. 180-181-182-183-184
Check that oil level with the vehicle on flat ground and
engine cold is included between the MIN and MAX ref-
erences on the reservoir body.
The level may go over the MAX line when the oil is hot.
If topping up is required, make sure the oil you use has
the same specifications as that already in the system.Power steering fluid consumption is very
low. If the fluid needs topping up a short
time after the last top-up, have the system
checked by a Fiat Dealership to ensure there are
no leaks.
Do not push the power steering all the way
for longer than eight seconds with the en-
gine running because it will cause noise and
risk damaging the system.
Because it is flammable, do not allow the
power steering fluid to come into contact
with hot parts of the engine.

The battery fluid is poisonous and corro-
sive. Avoid contact with the skin and eyes.
Keep naked flames or possible sources of sparks
away from the battery: risk of explosion or fire.
WARNING
Using the battery when the fluid is too low
can damage it irreparably and generate
a risk of explosion.
WARNING
AIR FILTER/POLLEN FILTER
Have the air filter or the pollen filter replaced by a Fiat
Dealership.
DIESEL FILTER
CONDENSATION DISCHARGE
(Multijet versions)
BATTERY
The battery is of the “limited maintenance” type: under
normal conditions of use, the electrolyte does not need
topping up with distilled water.
It does, however, need to be checked regularly at a Fiat
Dealership or by specialist personnel to make sure it is
working properly.
The presence of water in the supply circuit
may cause severe damage to the injection
system and irregular engine operation. If
the warning light comes on, go to a Fiat Dealer-
ship as soon as possible to have the system bled.
Water may have entered the tank if this appears
immediately after refuelling: if this happens, switch
the engine off immediately and contact a Fiat Deal-
ership.
