Recommendations for ventilation and air conditioning
In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:
F 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.
F Do not cover the sunshine sensor, located on the dashboard; this is used for regulation
of the air conditioning system.
F Operate the air conditioning system for at least 5 to 10 minutes, once or twice a month
to keep it in perfect working order.
F 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).
F 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.
F If the system does not produce cold air, switch it off and contact a CITROËN dealer or a
qualified workshop.
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.
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
perfectly normal.
Stop & Start
The heating and air conditioning
systems only work when the engine
is running. To maintain a comfortable
temperature in the passenger
compartment, you can temporarily
deactivate the Stop & Start system
(see the corresponding section).
