Ventilation / Heating

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.

Air distribution

Windscreen demisting-defrosting vents.

Front side window demisting-defrosting

vents.

Side adjustable air vents.

Central adjustable air vents.

Air outlets to the front footwells.

Air nozzles to the front footwells.

Stop & Start

The heating and air conditioning
systems only work when the engine is
running.
To maintain a comfortable temperature
in the passenger compartment, you can
temporarily deactivate the Stop & Start
system.
For more information on Stop & Start,
refer to the corresponding section.

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.

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.

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.

obtain a comfortable air flow.

This dial is used to arrange the distribution of
air in the passenger compartment by combining
several air outlets.

F If you place the air flow control

in position 0

, the system is

deactivated. However, a slight flow
of air, due to the movement of the
vehicle, can still be felt.

Avoid driving too long with the
ventilation off (risk of misting and
deterioration of air quality).

4. Air intake / Air recirculation

5. Air conditioning On / Off

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.

Switching on

F Press the "A/C"

button, the button's

indicator lamp comes on.

Switching off

F Press the "A/C"

button again, the button's

indicator lamp goes off.

Switching off may affect comfort levels
(humidity, condensation).

The intake of exterior air prevents the formation
of mist on the windscreen and side windows.
The recirculation of interior air isolates the
passenger compartment from exterior odours
and smoke.

F Press the button to recirculate

the interior air. The indicator
lamp comes on to confirm this.

Press the button again to permit the intake

of exterior air. The indicator lamp goes off
to confirm this.

Return to exterior air intake as soon as possible
to prevent deterioration of the the air quality
and the formation of mist.

This function allows hot or cold air to be
delivered selectively and more quickly.

The air conditioning does not operate
when the air flow adjustment control 2
is in position "0

To obtain cooled air more quickly, you
can use recirculation of interior air for a
few moments. Then return to fresh air
intake.
