Recommendations for ventilation and air conditioning
In order for these systems to be fully
effective, follow the operation and
maintenance guidelines below:
F To ensure that the air is distributed
evenly, keep the external air intake
grilles at the base of the windscreen, the
nozzles, the vents, the air outlets and
the air extractor in the boot free from
obstructions.
F Do not cover the sunshine sensor,
located on the dashboard; this is used
for regulation of the automatic 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.
To avoid the windows misting up and
deterioration in the quality of the air:
- do not drive for too long with the
ventilation switched off.
- do not keep air recirculation set for an
extended period.
