AIR CONDITIONING: information and operating instructions (2/2)
The refrigerant circuit may contain
fluorinated greenhouse gases.
Depending on the vehicle, you will find
the following information on label A af-
fixed inside the engine compartment.
The presence and location of the infor-
mation on label A depends on the ve-
hicle.
Do not open the refriger-
ant circuit . The fluid may
damage eyes or skin.
Before performing any
action in the engine com-
partment, the ignition must
be switched off (please see
the information on “Starting, stop-
ping the engine” in Section 2).

4.7
Engine oil grade
Refer to the Maintenance Service
Booklet for your vehicle.
Never run the engine in an
enclosed space as exhaust
gases are poisonous.
Engine oil change: if you
are changing the oil when
the engine is hot, be careful
not to scald yourself if the
oil overflows.
Filling: take care when
topping up the oil that
no oil drips onto engine
components - risk of fire.
Remember to refit the cap securely
as there is a risk of fire if oil splashes
onto hot engine components.Consult your approved Dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
ENGINE OIL LEVEL: topping up, filling (3/3)/OIL CHANGE
Exceeding the maximum
engine oil level
Under no circumstances
must the maximum fill level
be exceeded: risk of damage to the
engine and catalytic converter.
If the oil level exceeds the maximum
level, do not start your vehicle and
contact an approved Dealer.
Oil change
Service interval: refer to the
Maintenance Service Booklet for your
vehicle.
Oil change capacity
Please refer to the maintenance docu-
ment for your vehicle, or contact an au-
thorised dealer.
Always check the engine oil level using
the dipstick, as explained previously (it
should never fall below the minimum
level, or be over the maximum level on
the dipstick).
When working in the engine
compartment, ensure that
the windscreen wiper stalk
is in the park position.
Risk of injury.
Please note when work-
ing close to the engine that
it may be hot. The engine
cooling fan may also start
at any moment. The
 warning
light in the engine compartment re-
minds you of this.
Risk of injury.

4.8
Replacement intervals
Refer to the Maintenance Document for
your vehicle.
Checking intervals
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;
– anticorrosion protection of the cool- ing system.
LEVELS (1/3)
Coolant level
With the engine switched off and on
level ground, the level when cold must
be between the “MINI" and "MAXI"
marks on coolant reservoir 1.
Top this level up when cold before it
reaches the MIN mark.
No operations should be
carried out on the cooling
circuit when the engine is
hot.
Risk of burns.
Consult your approved dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
Please note when work-
ing close to the engine that
it may be hot. The engine
cooling fan may also start
at any moment. The
 warning
light in the engine compartment re-
minds you of this.
Risk of injury.

Before performing any
action in the engine com-
partment, the ignition must
be switched off (please see
the information on “Starting, stop-
ping the engine” in Section 2).

4.9
LEVELS (2/3)
Brake fluid level
This should be checked frequently, and
any time you notice even the slightest
loss in braking efficiency.
The level should be read with the engine
switched off and on level ground.Level 2
It is normal for the level to drop as
the linings become worn, but it should
never drop below the “MINI” warning
line.
If you wish to check the disc and drum
wear yourself, you should obtain the
document explaining the checking pro-
cedure from our network or from the
manufacturer’s website. Topping up
After any operation on the hydraulic cir-
cuit, a specialist must replace the fluid.
Only use fluids approved by our
Technical Department (and taken from
a sealed container).
Replacement intervals
Refer to the Maintenance Document for
your vehicle.
Please note when work-
ing close to the engine that
it may be hot. The engine
cooling fan may also start
at any moment. The
 warning
light in the engine compartment re-
minds you of this.

Before performing any
action in the engine com-
partment, the ignition must
be switched off (please see
the information on “Starting, stop-
ping the engine” in Section 2).
If there is an abnormal or repeated
drop in the fluid level, consult an ap-
proved dealer.

LEVELS (3/3)/FILTERS
Windscreen washer reservoir
Topping up
With the engine switched off, open
cap 3, fill until you can see the fluid,
then refit the cap.
Note: Regularly check the reservoir
level by topping up the liquid before
taking a trip. Liquid
Windscreen washer fluid. In winter, use
anti-freeze product. Use products rec-
ommended by an authorised dealer.
Note: do not use pure water (risk of
damage to the priming pump, limescale
building up on the pump and the jets).
Jets
To adjust the windscreen washer jets,
please consult an authorised dealer.
Depending on the vehicle, to find
out the fluid level, open cap
3 and
pull out the dipstick.
Filters
The replacement of filter elements (air
filter, passenger compartment filter,
diesel filter, etc.) is scheduled in the
maintenance operations for your vehi-
cle.
Replacement intervals for filter el-
ements: refer to the Maintenance
Document for your vehicle.

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.

4.16
BODYWORK MAINTENANCE (2/3)
Degrease or clean using
high-pressure cleaning
equipment or by spray-
ing on products not ap-
proved by our Technical
Department:
– mechanical components (e.g.:
engine compartment);
– underbody;
– parts with hinges (e.g.: inside the
doors);
– painted plastic external fittings (e.g.:
bumpers).
Doing this could give rise to corrosion
or operational faults.
What you should not do
Wash the vehicle in bright sunlight or
freezing temperatures.
Do not scrape off mud or dirt without
pre-wetting.
Allow dirt to accumulate on the exterior.
Allow rust to form following minor im-
pacts.
Do not use solvents not approved by
our Technical Department to remove
stains as this could damage the paint-
work.
Do not drive in snow or muddy condi-
tions without washing the vehicle, par-
ticularly under the wheel arches and
body.
