.Familiarisation

Limit the causes of excess consumption


Spread loads throughout the vehicle; place the heaviest items in the
bottom of the boot, as close as possible to the rear seats.
Limit the loads carried in the vehicle and reduce wind resistance (roof
bars, roof rack, bicycle carrier, trailer...). Use a roof box in preference.
Remove roof bars and roof racks after use.

At the end of winter, remove snow tyres and refit your summer tyres.



Observe the recommendations on
maintenance

Check the tyre pressures regularly, when cold, referring to the label in
the door aperture, driver's side.
Carry out this check in particular:


- before a long journey,

- at each change of season,

- after a long period out of use.
Don't forget the spare wheel and the tyres on any trailer or caravan.

Have your vehicle ser viced regularly (engine oil, oil filter, air filter...) and
obser ve the schedule of operations recommended by the manufacturer.



When refuelling, do not continue after the third cut-off of the nozzle to
avoid any over flow.

At the wheel of your new vehicle, it is only after the first 1 800 miles
(3 000 kilometres) that you will see the fuel consumption settle down to
a consistent average.

Air intake

The air circulating in the passenger compartment
is filtered and originates either from the outside via
the grille located at the base of the windscreen or
from the inside in air recirculation mode.


Air treatment

The incoming air follows various routes
depending on the controls selected by the
driver:


- direct arrival in the passenger
compartment (air intake),

- passage through a heating circuit (heating),

- passage through a cooling circuit (air
conditioning).

Comfort
In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:


)
To obtain an even air distribution, take care not to obstruct the exterior air intake grilles
located at the base of the windscreen, the nozzles, the vents and the air outlets, as well
as the air extractor located in the boot.

)
Do not cover the sunshine sensor, located on the dashboard; this is used for regulation
of the air conditioning system.

)
Operate the air conditioning system for at least 5 to 10 minutes, once or twice a month
to keep it in per fect working order.

)
Ensure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly.
We recommend the use of a combined passenger compartment filter. Thanks to its
special active additive, it contributes to the purification of the air breathed by the
occupants and the cleanliness of the passenger compartment (reduction of allergic
symptoms, bad odours and greasy deposits).

)
To ensure correct operation of the air conditioning system, you are also advised to have
it checked regularly as recommended in the maintenance and warranty guide.

)
If the system does not produce cold air, switch it off and contact a CITROËN dealer or a
qualified workshop.











Recommendations for ventilation and air conditioning


If after an extended stop in sunshine,
the interior temperature is very high, first
ventilate the passenger compartment for
a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
The air conditioning system does not
contain chlorine and does not present
any danger to the ozone layer.

The condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
per fectly normal.

When towing the maximum load on a steep gradient in high temperatures, switching off the
air conditioning increases the available engine power and so improves the towing ability.

Checks













12 V battery


Electrolyte level

For access to the battery, refer to the
"12V battery" section.
Refer to the maintenance and
warranty guide for details of the
replacement inter vals for these
components.



















Air filter and passenger compartment filter

Replace the oil filter each time the
engine oil is changed.
Refer to the maintenance and
warranty guide for details of the
replacement inter val for this
component.














Oil filter

If necessary, top up using distilled water,
removing the battery cap from each cell.
Check the electrolyte level at least once
a month.
When carrying out work on the battery, refer
to "12V battery" section for details of the
precautions to be taken before disconnecting
the battery and following its reconnection.

Unless other wise indicated, check these components in accordance with the maintenance and warranty guide and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.

The electrolyte level must be between the
"LOWER LEVEL" and "UPPER LEVEL" marks. Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle
(e.g. city driving), replace them twice as often
if necessary
.
A clogged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.
