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.  
Temporarily deactivate the Stop & Start  
system to maintain a comfortable temperature  
in the passenger compartment.

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  
a qualified workshop.  
Condensation created by the air  
conditioning results in a discharge of  
water underneath the vehicle. This is perfectly  
normal.  
Heating / Manual air  
conditioning  
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).  
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.  
The heating only operates when the engine is  
running.  
To ensure correct operation of the  
air conditioning system, have it checked  
according to the recommendations in the  
Maintenance and Warranty Guide.  
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!  
Stop & Start
