Ease of use and comfort -> Heating and Ventilation for Your Citroen C4 SUV Third Generation (2020-2025)

Ease of use and comfort  
consumption in turn decreases energy  
consumption.  
Air distribution  
► 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 good working order.  
► If the system does not produce cold air,  
switch it off and contact a CITROËN dealer or  
a qualified workshop.  
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.

Prolonged use of heated seats is not  
recommended for people with sensitive  
skin.  
There is a risk of burns for people whose  
perception of heat is impaired (e.g. illness,  
taking medication).  
To keep the heated pad intact and to prevent  
a short circuit:  
– Do not place heavy or sharp objects on the  
seat.  
– Do not kneel or stand on the seat.  
– Do not spill liquids onto the seat.  
– Never use the heating function if the seat  
is damp.

3. Adjustable and closable side air vents  
4. Adjustable and closable central air vents  
5. Air outlets to the front footwells  
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.  
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.  
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.  
Controls  
Condensation created by the air  
conditioning results in a discharge of  
water underneath the vehicle. This is perfectly  
normal.  
Depending on version, the controls are  
accessible in the touch screen or are  
grouped together on the centre console panel.

► 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. Its specific active additive  
helps protect against polluting gases and bad  
smells.  
To ensure correct operation of the  
air conditioning system, have it checked  
according to the recommendations in the  
Manufacturer’s service schedule.

► Press one of the buttons 3 to adjust the air  
distribution inside the passenger compartment.  
The lighting of the button indicates that air  
is being blown in the specified direction. It  
is possible to activate the following buttons  
simultaneously:  
– Central and side air vents + footwells.  
– Windscreen and side windows + footwells.  
The air conditioning system only operates with  
the engine running.  
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 system, refer to the corresponding  
section.  
Air conditioning on/off  
The air conditioning system is designed to  
operate effectively in all seasons, with the  
windows closed.  
Adjusting the temperature  
► Turn the knob 1 from blue (cold) to red (hot).  
Air flow adjustment  
► Turn the thumbwheel 2 to obtain a sufficient  
air flow to ensure your comfort.  
It is used to:  
– lower the temperature in summer,  
– increase the effectiveness of demisting in  
winter, above 3°C.

deactivated), the temperature in the vehicle  
will no longer be controlled. A slight flow of air  
can still be felt, due to the forward movement  
of the vehicle.  
Selecting this mode reduces electrical  
energy consumption, but restricts the  
performance of the heating and air  
conditioning systems, although it does not  
deactivate them.
