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 routesdepending on the controls selected by thedriver:
- 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 centreconsole.

Recommendations for ventilation and air conditioning


If after an extended stop in sunshine, the interior temperature is veryhigh, 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 notcontain 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 wellas 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 monthto keep it in per fect working order. )
Ensure that the passenger compar tment 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 theoccupants 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 haveit checked regularly as recommended in the ser vicing booklet.
)
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 theair conditioning increases the available engine power and so improves the towing ability.


The condensation created by the air conditioning results in a dischargeof water under the vehicle which is perfectly normal.




Stop & Start
The heating and air conditioning systems only work when the engine is running. To maintaina comfor table temperature in the passenger compartment, you can temporarily deactivatethe Stop & Start system (see "Driving").

Manual air conditioning
The air conditioning system operates with the engine running.
1. Temperature adjustment
)
Turn the dial to select a
position between blue (cold)and red (hot) so as to adjust
the temperature to your
requirements.

2. Air fl ow adjustment
This dial is used to increase or
decrease the speed of the air
booster fan.

3. Air distribution adjustment

This dial is used to arrange the distribution of
air in the passenger compartment by combiningseveral air outlets.
)If you place the air flow control in position 0, the system isdeactivated. However, a slight flow of air, due to the movement of thevehicle, can still be felt.
) Turn the dial from position 1

indicator lamp comes on.

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

e recirculation of interior air isolates the passenger compartment from exterior odours and smoke.
Return to exterior air intake as soon as possible
to prevent deterioration of the the air qualit
y and the formation of mist.
)Press the button again to permit the intake
of exterior air. The indicator lamp goes off

Dual-zone digital air conditioning The air conditioning system operates when the engine is running.
Automatic operation
1. Automatic comfort programme
We recommend the use of one of
the three AUTO modes available:
they provide optimised regulation of
the temperature in the passenger compartment according to the comfort value
that you have chosen.
These three modes automatically adjust the
air flow, according to the desired setting, while also maintaining the desired comfort value.
) Press the "AUTO"
button repeatedly:


- a first indicator lamp comes on; the
"li
ght" setting mode is selected,

- a second indicator lamp comes on; the"medium" setting mode is selected,

- a third indicator lamp comes on; the
"intense" mode setting is selected.

When the engine is cold, the air flow will reach its optimum level
progressively, taking account of the weather and the desired comfort levelso as to avoid too great a distributionof cold air. On entering the vehicle, if the interior temperature is much colder or warmer than the comfort value, there is noneed to change the value displayed in order to obtain the comfor t required.The system corrects the differencein temperature automatically and asquickly as possible.
This s
ystem is designed to operate effectivelyin all seasons, with the windows closed.

5. Air conditioning On/Off
)Press this button to switch off
the air conditioning.
Switching the system off could result in

direct the air flow towards:
- th
e windscreen and side windows (demisting or defrosting),
- the outer and centre air vents,
- th
e footwells.

You can combine the three orientations toobtain the desired air distribution.


7. Air fl ow adjustment
)Turn this control to the left todecrease the air flow or to theright to increase the air flow.

8. Air intake/Air recirculation
)Press this button for recirculation of the interior air. The indicator lamp in the button comes on. The air
flow indicator lamps, between the
two fans, come on progressively in relation to
the value requested.

9. "REST" function: ventilationwith the engine off

Even with the engine is off, you canoperate the ventilation for afew minutes.
Air recirculation enables the passen
ger compartment to be isolated from exterior odours and smoke. )
As soon as possible, press this button
again to permit the intake of outside air andprevent the formation of condensation. The
indicator lamp in the button goes off.
For example, while
you are away from the
vehicle, the passengers can still enjoy some air circulation without having the engine running.
This function is available after switching on the
ignition, as well as after stopping the engine.
The period that the function is available
depends on the state of char
ge of the battery.
You can activate the "REST" function while the
air conditioning control screens are on.
