Vent ilat ion


Air intake

The air circulating in the passenger compar tment
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.


Air treatment

The incoming air follows various routes
depending on the controls selected by
the driver:


- direct arrival in the passenger compartment
(air int ake),

- passage through a heating circuit (heating),

- passage through a cooling circuit (air
conditioning).
The temperature control enables you to obtain
the level of comfor t required by mixing the air of
the various circuits.
The air distribution control enables you to
diffuse the air in the passenger compar tment
combining several air vents.
The air flow control enables you to increase or
reduce the speed of the ventilation blower.


Control panel

The controls of this system are grouped
together on control panel A
on the centre
console. Depending on the model, the functions

Recommendations for ventilation and air conditioning


If after an extended stop in sunshine,
the interior temperature is very
high, first ventilate 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 conditioning system does not
contain chlorine and does not present
any danger to the ozone layer. In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:


)
To obtain an even air distribution, take care not to obstruct the exterior air intake grilles
located at the base of the windscreen, the nozzles, the vents and the air outlets, as well
as the air extractor located in the boot.

)
Do not cover the sunshine sensor, located on the dashboard; this is used for regulation
of the digital air conditioning system.

)
Operate the air conditioning system for at least 5 to 10 minutes, once or twice a month
to keep it in per fect working order.

)
Ensure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly (refer to the "Checks" section).
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).

)
To ensure correct operation of the air conditioning system, you are also advised to have
it checked regularly as recommended in the Maintenance and Warranty Guide.

)
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 and so improves the towing ability.
The condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
per fectly normal.

1. Temperature adjustment



)
Turn the dial from blue
(cold) to red (hot) to adjust
the temperature to your
requirements.



2. Air fl ow adjustment



)
Turn the dial from position 1

to position 5
to obtain a
comfortable air flow.

)
If you place the air flow control
in position 0
(deactivation of the
system), the temperature is no
longer maintained at a comfor table
level. However, a slight flow of air,
due to the movement of the vehicle,
can still be felt.



3. Air distribution adjustment

Windscreen and side windows.
Windscreen, side windows and
footwells.
Footwells.
Central and side vents.
The air distribution can be
adapted by placing the dial
in an intermediate position.


4. Air intake/Air recirculation

The intake of exterior air avoids the formation of
mist on the windscreen and side windows.
The recirculation of interior air insulates the
passenger compar tment from exterior odours
and smoke.
Return to exterior air intake as soon as possible
to prevent deterioration of the air quality and
the formation of mist.

Manual control panel



)
Move the manual control to
the left to be in the "recycling
interior air" position.

)
Move the manual control to the
right to return to the "fresh air
intake" position.
