Air distribution

1. Windscreen demisting/defrosting vents
2. Front side window demisting/defrosting vents
3.Adjustable and closable side air vents
4. Adjustable and closable central air vents
5. Air outlets to the front footwells
6. Air outlets to the rear footwells
Advice
Using the ventilation and air
conditioning system
► To ensure that 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.
► Do not cover the sunshine sensor located on the dashboard; this sensor is used to
regulate the automatic air conditioning
system.
► Operate the air conditioning system for at least 5 to 10 minutes once or twice a month to
keep it in perfect working order.
► If the system does not produce cold air, switch it off and contact a CITROËN dealer or

Avoid driving for too long with the
ventilation off or with prolonged operation
of interior air recirculation. Risk of misting and
deterioration of the air quality!
If the interior temperature is very high after the vehicle has stood for a long
time in the sunshine, air 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.
Condensation created by the air
conditioning results in a discharge of
water underneath the vehicle. This is perfectly
normal.
Servicing the ventilation and air
conditioning system
► Ensure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly.
We recommend using a composite passenger
compartment filter. Thanks to its special active
additive, this type of filter helps to purify the
air breathed by the occupants and keep the
passenger compartment clean (by reducing
allergic symptoms, unpleasant odours and
greasy deposits).
► To ensure correct operation of the air conditioning system, have it checked
according to the recommendations in the
Maintenance and Warranty Guide.
Stop & Start
The heating and air conditioning systems
only operate when the engine is running.
Temporarily deactivate the Stop & Start
system to maintain a comfortable temperature
