(cold climates, town use, long periods of idling) or, in any case, every 5 years.
(3) The actual interval for changing the oil and replacing the engine oil filter depends on the car usage conditions and is signalled by the warning light

❒ operation of lighting system
(headlights, direction indicators, hazard
warning lights, etc.);
❒ operation of windscreen

Carry out the check with the vehicle
parked on level ground.
DEMANDING USE OF THE CAR
If the vehicle is used mainly under one of
the following conditions:
❒ trailer or caravan towing;
❒ dusty roads;
❒ short repeated distances (less than

CHECKING LEVELS
The topping-up plug 2 and the dipstick 1 for checking the engine oil level and the reservoir 3 for the engine coolant can be accessed
by lifting the tailgate (see the procedure in the “Boot/Bonnet” paragraph in the “Knowing your car” chapter).

SERVICING AND CARE

ENGINE OIL
Check that the oil level is between the
MIN and MAX marks on the dipstick
1 fig. 87.
For this check, take out the dipstick from
its seat, clean it with a lint-free cloth,
reinsert the dipstick; take it out again and
check the oil level.
119)
If the oil level is near or under the MIN
mark, add oil through the filler 2 fig. 87
until it reaches the MAX mark.
15)
Tool 1 shown in fig. 89 and stored in the
car, must be used to
undo and refasten the filler cap.
Take out the engine oil dipstick 1 fig. 87,
clean it with a lint-free cloth  and reinsert
it. Extract the engine oil dipstick again
and check that the level is between the
MIN and MAX marks on the dipstick.
119)
WARNING Make sure that the oil cap is
tightened properly in its seat after
topping the oil up.
After refitting the cap, remove tool 1 fig.
89 before closing the bonnet and place it
back in the housing to prevent misplacing
it and avoid the risk of causing damage to
the engine.
The range between the MIN and MAX
levels corresponds to approximately 1
litre of oil.
89A0L0231
Engine oil consumption
16) 4)
The maximum engine oil consumption is
usually 400 grams every
1000 km.
When the car 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 run for a few
seconds and wait a few minutes after
switching it off before checking the level.
ENGINE COOLANT FLUID
120) 17)
The coolant level must be checked when
the engine is cold and must range
between the MIN and MAX marks on the
reservoir.
If the level is too low, unscrew reservoir
plug 3 fig. 87 and add the fluid described
in the “Fluids and lubricants” paragraph of
the “Technical Specifications” chapter.

117
IMPORTANT The washing should take
place with the engine cold and the
ignition key 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.
6)Detergents pollute water. Only wash
your vehicle in areas equipped to collect
and treat wastewater from this type of
activity.
WARNING
24)In order to preserve the aesthetic
appearance of the paint abrasive
products and/or polishes should not be
used for cleaning the car.
25)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 vehicle. 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
INTERIOR
130) 131)
Periodically check the cleanliness of the
interiors, beneath the mats, also to
prevent damage to carbon parts.
To remove and reposition the mats in the
passenger compartment, proceed as
follows:
❒ undo the screws with folding ring 1
fig. 103, driver side and passenger side;
❒ separate the Velcro fabric strips 2 in
the front area under the mats, lifting
them from the floor.
Reposition the mats on the floor, making
sure that the holes at the back of the
mats coincide with the screw housings on
the floor.
