is running. Pressing this button 
activates the rapid demisting-

This function switches off automatically to 
prevent excessive energy consumption. It

intake position permits renewal 
of the air in the passenger 
compartment.
Windscreen and side windows
The ventilation outlets located at the base 
of the windscreen and the side vents for the 
side windows increase the effectiveness 
of the demisting and defrosting. Do not 
obstruct these air outlets.
The pollen filter continuously and effectively 
filters dust.
Air recirculation (which can be activated by 
the driver or the passenger) isolates the 
passenger compartment from the exterior 
atmosphere. However, this position should 
only be used temporarily, normal use is to 
drive with the control positioned with the 
exterior air intake open.

In order to be effective, the air conditioning 
should only be used with the windows 
closed. However, if the interior temperature 
remains high after a prolonged period 
parked in the sun, first ventilate the 
passenger compartment for a few minutes. For even air distribution, ensure that the 
exterior air intake grille located at the base 
of the windscreen, the side and central 
vents, the air outlets on the floor and the air 
extractor at the rear are not obstructed.
The air conditioning is useful in all seasons 
as it eliminates condensation and air 
humidity.
 Operate the air conditioning system for
  
5 to 10 minutes, once or twice a month, 
to keep it in good working order.
Have the filter elements (air filter and 
passenger compartment filter) replaced 
regularly. If you drive in a dusty environment, 
have them replaced twice as often.
It is normal that the condensation created by 
the air conditioning system results in a flow 
of water which may form a puddle under the 
vehicle when parked.
If the system does not produce cold air, 
do not use it and have it checked by a 
CITROËN dealer or a qualified workshop.
"Leave them open"
For optimum distribution and diffusion of hot 
or cool air in the passenger compartment, 
there are: 4 adjustable central vents, of 
which 2 can be directed sideways (right 
or left) towards the top of the body and 
4
  side vents which can be directed towards 
the passengers. The air vents directed 
towards the floor of the vehicle complete the 
equipment.

recirculation of interior air
This position should only be 
temporary.
Used with the air conditioning 
switched on and the fan setting

If your vehicle is fitted with an additional 
air conditioning unit, located in the rear of 
the vehicle: the distribution duct located in 
the roof and the individual diffusion vents 
provide a perfect diffusion of cold air.
The warm air diffused at the floor, from the 
front air conditioning unit, is distributed at 
the feet of the rear passengers of rows 2 
and 3.
A warm air diffusion vent, located on the rear 
left wheelarch, may complete the assembly 
for the feet of the rear passengers of row 3.
Additional heating
This is passenger compartment heating, 
additional to the standard equipment.
It can operate independently of the engine.
Additional heater or programmable 
additional heating
This is an additional, programmable and 
separate system which heats the Diesel 
engine hot coolant loop to make starting 
easier.
It improves the demisting and defrosting 
performance and that of the heated seats, if 
fitted to the vehicle.
The passenger compartment heating is 
brought up to temperature more rapidly.
This system must be programmed to start up 
before you enter the vehicle. On the 5-9 seats version, it is 
located at the rear. Depending 
on the model version, the air 
diffusion is either direct from the 
rear or comes from the rail located under 
each of the two rows of seats.
Press this control to activate/
deactivate the heating. The LED 
is on if the heating is activated.
When rapid demisting and 
defrosting is required, switch off the control.
Automatic additional heating
This is an additional system which starts 
automatically when the ignition is switched 
on. Its activation depends on the ambient 
temperature and the temperature inside the 
vehicle.
It switches off automatically once the 
heating system is started manually.
