Familiarisation
Limit the causes of excess
consumption
Spread loads throughout the vehicle; placethe 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 inpreference.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 aper ture, driver's side.
Carry out this check in par ticular:- 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 onany trailer or caravan.
Have your vehicle ser viced regularly (engine oil, oil filter, air filter...) and obser ve the schedule of operations recommended by themanufacturer.


When refuelling, do not continue after the3 rd
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 settledown to a consistent average.

Vent ilat ion
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 thedriver:
- direct arrival in the passenger compartment (air intake),
- passage through a heating circuit (heating),
- passage through a cooling circuit (air conditioning).
Control panel
The controls of this system are grouped
together on control panel A on the centreconsole.

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 wellas the air extractor located in the boot. )
Do not cover the sunshine sensor, located on the dashboard; this is used for regulation of the digital air conditioning system. )
Operate the air conditioning system for at least 5 to 10 minutes, once or twice a monthto keep it in per fect working order. )
Ensure that the passenger compar tment 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 theoccupants 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 haveit checked regularly as recommended in the ser vicing booklet. )
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, firstventilate 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 notcontain chlorine and does not present any danger to the ozone layer.

The condensation created by the air conditioning results in a dischargeof water under the vehicle which is perfectly normal.


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

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 disconnectingthe battery and following its reconnection.
Unless other wise indicated, check these components in accordance with the ser vicin
g booklet and according to your engine.

Dependin
g on the environment (e.g. dustyatmosphere) and the use of the vehicle (e.g. city driving), replace them twice as often if necessary.y A clogged passenger compar tment filter mayhave an adverse effect on the performance
of the air conditioning system and generate undesirable odours.
