Ventilation

Air intake

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.

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).

Control panel

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

Windscreen demisting-defrosting vents.

Front side window demisting-defrosting

vents.

Side adjustable air vents.

Air distribution

Ease of use and comfort

In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:
F

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 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.

Ensure that the passenger compartment filter is in good condition and have the filter

elements replaced 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).

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.

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.

Humid air cooled quickly by the
vehicle's air conditioning system may
produce condensation at the vent
outlets.
This phenomenon disappears after a
few seconds.

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.

Manual heating / air conditioning

The system operates with the engine running.

1. Temperature setting

Turn the temperature control

dial to the right to raise the
temperature, and to the left to
lower it.

To avoid misting and deterioration of the air
quality in the passenger compartment, ensure
that an adequate air flow is maintained.

3. Air distribution setting

Place the dial in the desired

position, to direct air towards:

the centre and side vents,

The air distribution can be modulated by
placing the dial in intermediate positions.

2. Air flow setting

Turn the dial to the right to

intake of exterior air is deactivated, and you are
in air recirculation.
Do not drive for long with interior air
recirculation, except in truly exceptional
atmospheric conditions.

The air conditioning is designed to operate
effectively in all seasons, with the windows closed.
It enables you to:
- lower the temperature, in summer,
- increase the effectiveness of the demisting

in winter, above 3 °C.

Automatic operation

Set the temperature control dial 1 to the

temperature required.

Place the air flow control dial 2 in

the "AUTO"

position.

Place the air distribution adjustment dial 3

in the "AUTO"

position.

When the engine is cold, to avoid an
excessive distribution of cold air, the
ventilation will reach its optimum level
gradually.
On entering the vehicle, the interior
temperature may be much colder
(or warmer) than the temperature
setting. There is no need to change the
temperature setting in order to reach
the comfort required rapidly.
The automatic regulation of the air
conditioning will operate to correct the
temperature difference as quickly as
possible.

In automatic mode:
F

when the temperature is set to maximum

(Rapid heating), the intake of exterior air is
activated and the air conditioning stops.

when the temperature is set to minimum

(Rapid cooling), air recirculation is
activated and the air conditioning operates.

The system controls the air distribution, the flow,
the temperature and the air intake to ensure
the level of comfort selected and adequate air
circulation in the passenger compartment. No
further action on your part is required.
