Citroen C3: Ease of use and comfort / Ventilation

Air intake

The air circulating in the passenger compartment is filtered and originates either from the exterior, via the grille located at the base of the windscreen, or from the inside in air recirculation mode.


Depending on version, the controls are accessible in the "Air conditioning" touch screen menu or are grouped together in the control panel on the centre console. The demisting/defrosting controls for the windscreen and the rear screen are located below the touch screen, or on the centre console panel located below the audio system.

  • Citroen C3. Ventilation 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 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, enhancing the towing capacity.

Citroen C3. Ventilation 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!

Citroen C3. Ventilation 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.

Citroen C3. Ventilation Condensation created by the air conditioning results in a discharge of water underneath the vehicle. This is perfectly normal.

  • 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.

Citroen C3. Ventilation 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 in the passenger compartment.

For more information on the Stop & Start, refer to the corresponding section.
