4.3
Reading the oil levelThe oil level should be read with the ve-
hicle on level ground, after the engine
has been switched off for some time.
The dipstick must be used to read
the exact oil level and ensure that
the maximum level is not exceeded
(risk of engine damage). Refer to the
following pages.
It is normal for an engine to use oil for
lubrication and cooling of moving parts
and it is normal to top up the level be-
tween oil changes.
However, contact your approved
Dealer if more than 0.5 litres is being
consumed every 600 miles (1,000 km)
after the running in period.
Oil change frequency: check the oil
level from time to time and certainly
before any long journey to avoid the
risk of damaging your engine.
ENGINE OIL LEVEL: general information

C
In order to prevent splashback, it is
recommended that a funnel be used
when topping up/filling with oil.
– Remove the dipstick and wipe with a
clean, lint-free cloth;
– push the dipstick in as far as it will go (for vehicles equipped with a cap-
type dipstick C, screw the cap in as
far as it will go);
– take out the dipstick again;
– read the level: it should never go below the “min” A or above the
“max” B.
Once the operation has been com-
pleted, ensure that the dipstick is
pushed in as far as it will go or that
the “cap-type dipstick” is completely
screwed in.
Deactivate the Stop and
Start function for any opera-
tion performed in the engine
compartment.
Consult your approved Dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
Exceeding the maximum
engine oil level
Under no circumstances
must the maximum fill
level B be exceeded: risk of damage
to the engine and catalytic conver-
ter.
If the oil level exceeds the maximum
level, do not start your vehicle and
contact an approved Dealer.

4.4
Topping up/filling
The vehicle must be parked on level
ground and the engine should be cold
(for instance, before the engine is
started up for the first time in the day).
– Unscrew the cap 2;
– top up the level (as a guide, the ca-pacity between the “MINI” and the
“MAXI” reading on the dipstick 1
is between 0.20 and 0.24 gallons
(0.9 and 1.1 litres) depending on the
engine);
– wait for approximately 10 minutes to allow the oil to flow into the engine;
– check the level using the dipstick 1
(as described above). Once the operation has been com-
pleted, ensure that the dipstick is
pushed in as far as it will go and that
the cap is completely screwed in.
ENGINE OIL LEVEL: topping up/filling (1/2)
Do not exceed the “MAXI” level and
do not forget to refit the cap
2 and
the dipstick 1.
In order to prevent splashback, it is
recommended that a funnel be used

Frequency of checking coolant level
Check the coolant level regularly
(very severe damage is likely to be
caused to the engine if it runs out of
coolant).
If the level needs to be topped up, only
use products approved by our Technical
Department which ensure:
– protection against freezing;
– an anti-corrosion protection for the cooling system.
No operations should be
carried out on the cooling
circuit when the engine is
hot.
Risk of burns.

BODYWORK MAINTENANCE (1/3)
You should
Wash your car frequently, with the
engine off, with cleaning products rec-
ommended by the manufacturer (never
use abrasive products). Rinse thor-
oughly beforehand with a jet:
– spots of tree resin and industrial
grime;
– mud in the wheel arches and under-
neath the body which forms damp
patches;
– bird droppings , which cause a
chemical reaction with the paint that
rapidly discolours paintwork and
may even cause the paint to peel
off;
wash the vehicle immediately to
remove these marks since it is im-
possible to remove them by polish-
ing;
– salt, particularly in the wheel arches
and underneath the body after driv-
ing in areas where the roads have
been gritted.
Remove any plant matter (resin, leaves,
etc.) from the vehicle regularly.
A well-maintained vehicle will last
longer. It is therefore recommended to
maintain the exterior of the vehicle reg-
ularly.
Your vehicle has been treated with very
effective anti-corrosion products. It is
nevertheless subject to various outside
influences.
Corrosive agents in the atmosphere
–
atmospheric pollution (built-up and
industrial areas);
– saline atmospheres (near the sea,
particularly in hot weather);
– seasonal and damp weather condi-
tions (e.g. road salt in winter, water
from road cleaners, etc.).
Minor impacts
Abrasive action
Dust and sand in the air, mud, road grit
thrown up by other vehicles, etc.
You should take a number of minor pre-
cautions in order to safeguard your ve-
hicle against such risks. Respect local regulations about wash-
ing vehicles (e.g. do not wash your ve-
hicle on a public highway).
Observe the vehicle stopping distances
when driving on gravelled surfaces to
prevent paint damage.
Repair, or have repaired quickly, areas
where the paint has been damaged, to
prevent corrosion spreading.
Remember to visit the body shop pe-
riodically in order to maintain your
anti-corrosion warranty. Refer to the
Maintenance Document.
If it is necessary to clean mechani-
cal components, hinges, etc., spray
them with products approved by our
Technical Department to protect them
after they have been cleaned.
We have selected special products
to care for your vehicle and you can
obtain these from the manufactur-
er’s accessory outlets.
