Ease of use and comfort -> Ventilation for Your Citroen C4 Cactus SUV First Generation (2014-2018)

Ease of use and comfort  
This system automatically and progressively  
changes between the day and night uses by  
means of a sensor, which measures the light  
from the rear of the vehicle.  
Control panel  
The controls of this system are  
accessible in the "Air conditioning"  
menu of the touch screen A.  
In order to ensure optimum visibility during  
your manoeuvres, the mirror lightens  
automatically when reverse gear is  
engaged.  
The demisting/defrosting controls for the  
windscreen and rear screen are located below  
the touch screen.  
Air distribution  
1. Windscreen demisting/defrosting vents.  
Ventilation  
2. Front side window demisting/defrosting  
vents.  
Air intake  
3. Adjustable side air vent (driver only).  
4. Central adjustable air vents.  
The air circulating in the passenger  
compartment is filtered and originates either  
from the outside via the grille located at the  
base of the windscreen or from the inside in air  
recirculation mode.  
5. Air outlets to the front footwells.  
6. Air outlets to the rear footwells.  
Air treatment  
The incoming air follows various routes  
depending on the controls selected by the  
driver:  
-
direct arrival in the passenger compartment  
(air intake),  
-
-
passage through a heating circuit (heating),  
passage through a cooling circuit (air  
conditioning).

Recommendations for ventilation and air conditioning  
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.  
In order for these systems to be fully  
effective, follow the operation and  
maintenance guidelines below:  
F If the system does not produce cold air,  
switch it off and contact a CITROËN  
dealer or a qualified workshop.  
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 Replace the filter elements 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).  
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.

The condensation created by the air  
conditioning results in a discharge of water  
under the vehicle which is perfectly normal.  
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.  
Stop & Start  
-
do not keep air recirculation set for an  
extended period.  
The heating and air conditioning systems  
only work when the engine is running.  
Temporarily deactivate the Stop &  
Start system to maintain a comfortable  
temperature in the passenger  
compartment.  
For more information on Stop & Start,  
refer to the corresponding section.  
F To ensure correct operation of the air  
conditioning system, have it checked  
according to the recommendations in the  
Maintenance and Warranty Guide.
