Citroen C4: Heating and 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.

Controls

Depending on version, the controls are accessible in the touch screen or are grouped together on the centre console panel.

Air distribution

1. Windscreen demisting/de-icing vents
2. Front side window demisting/de-icing 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
7. Adjustable and closable air vents

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.

When towing a large load on a steep gradient in high temperatures, switching off the air conditioning increases the available engine power, enhancing the towing capacity.

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.

► To ensure correct operation of the air conditioning system, have it checked according to the recommendations in the Manufacturer's service schedule.

Electric vehicles

Selecting the ECO driving mode reduces electrical energy consumption, but restricts the performance of the heating and air conditioning systems, although it does not deactivate them.

Stop & Start / e-Auto mode

The heating and air conditioning systems only operate when the engine is running.
