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.
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.
