RECOMMENDATIONS FOR VENTILATION AND AIR CONDITIONING
In order for these systems to be fully effective, follow the guidelines on operation
and maintenance below:
If the interior temperature remains very high after the vehicle has been
parked in the sun for a considerable time, fi rst ventilate the passenger
compartment for a few minutes.
Place the air fl ow control at a suffi cient level to provide an adequate renewal
3
of air in the passenger compartment.
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 passenger
compartment on both sides of the rear shelf.
Do not cover the sunshine sensor, located on the dashboard (behind
the instrument panel); this is used for regulation of the air conditioning
system.
Operate the air conditioning system for 5 to 10 minutes, once or twice a
month to keep it in good working order.
Ensure that the passenger compartment fi lter is in good condition and have
the fi lter elements replaced regularly (refer to the "Checks" section).
We recommend the use of a combined passenger compartment fi lter.
Thanks to its second special active fi lter, it contributes to the purifi cation
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.
If the system does not produce cold air, do not use it and contact a
CITROËN dealer or a qualifi ed workshop.
When towing the maximum load on a steep gradient in high temperatures,
switching off the air conditioning saves engine power and so improves towing
capacity.

The condensation created by
the air conditioning results in a
discharge of water under the ve-
hicle which is perfectly normal.
The air conditioning system does
not contain chlorine and does not
present any danger to the ozone
layer.
