CORRECT USE OF THE AIR CONDITIONING
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 is not obstructed and that
the side and central vents, the air outlets on
the floor and the air extractor at the rear are
open.
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 contact a CITROËN dealer.

"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.

WITH MANUAL ADJUSTMENT

If your vehicle is fitted with these controls,
they are located on the dashboard on the
centre console control panel.
Temperature adjustment
Control positioned:


- in the blue zone provides cool air,


Air flow

The force of the blown air, from
the vents, varies from 1 to the
strongest 4. Remember to adjust
this control in order to reach the
ambient air comfort level. To switch off the
blower, place the control in position 0.


Air conditioning

The air conditioning mode can only operate
with the engine running.
The air blower must be set to at
least 1.
Pressing the button triggers the
operation of the air conditioning,
the LED is on. Pressing the button again
switches the function off and the LED is
switched off.


Air distribution

The air supply distribution is directed by the
control turned towards:
the side vents and the central
vents,
the side vents, the central vents
and the footwells,
the footwells,
the windscreen, the footwells and
the side windows,

Recommended settings for the air conditioning
For optimum operation of the system, the settings below are recommended:
Recirculation of interior air

This position should only be
temporary.
Used with the air conditioning
switched on and setting of the
force of blown air (from 1 to 4), recirculation
enables you to obtain the required ambient
air comfort level with both hot or cold
settings.
Recirculation temporarily prevents exterior
odours and smoke from entering the
passenger compartment.

MONO-ZONE DIGITAL AIR
CONDITIONING
If your vehicle is fitted with this system, the
controls are located in the middle of the
dashboard. The system can be identified by
its control screen.
AUTO mode
Switching on FULL AUTO
mode: pressing the AUTO
control switches on the system's
functions, confi rmed by the display
of FULL AUTO
. This is the normal operating
mode for the digital air conditioning system.
Using the moving ring surrounding the AUTO
control, set the comfort temperature to be
reached according to a setting between:


- HI (High to ≈ 32) and,

- LO (Low to ≈ 16).
The system controls the distribution,
fl ow and intake of air to ensure comfort
equivalent to the setting displayed and suffi cient recirculation of air in the passenger
compartment.
No further adjustments are required.
Control screen for your digital air conditioning
system.
When the engine is running and the air
conditioning is on, this symbol and the
message FULL AUTO
are displayed.
The other components are displayed
according to the settings selected by the user.

AUTO mode with personalisation

Switch on in AUTO
mode, certain
settings can be modified: the
distribution, the air flow, the air
conditioning and the air intake/
recirculation.
The display changes from FULL AUTO
to

To return to fully automatic operation, press
this button again. The display on the control
panel changes from AUTO
to FULL AUTO

If the system is not able to maintain
the setting selected following manual
adjustments, the setting flashes then AUTO
is cleared. Press the AUTO
control to return
to the automatic settings.

The settings range between:


- increasing the interior ambient air
temperature HI (High) which goes up to
to a maximum setting of 32,

- cooling the interior ambient air
temperature LO (Low) which goes down
to a setting of 16.

Air distribution

A press illuminates the LED on the buttons
which distribute the air flow towards:
the windscreen and front side
window vents (demisting/
defrosting the windows),
the central and side vents (chest
and face),
the vents in the front and rear
areas (feet).
The combination of buttons permits
improvement of air distribution.
Air flow

Successive presses of this button
increase (+) or reduce (-) the
force of the air flow to the interior.


Intake of exterior air/
recirculation of interior air
When the LED is on, the air
recirculates inside the passenger
compartment to prevent the entry of exterior
odours and smoke. This position should be
temporary.
When the ambient air comfort level has been
reached, pressing the button switches the
LED off and reopens the exterior air intake.
Pressing the AUTO
button also restores
the intake of exterior air. Returning to this
position permits renewal of the air in the
passenger compartment and demisting.
Pressing the AUTO
button again restores
the FULL AUTO
function.


Rapid demisting/defrosting

Pressing this control permits
rapid clearing of the windows.
The LED is on.
The system manages the air conditioning,
the flow and intake of air, the defrosting
of the rear screen and provides optimum
distribution of the air to the windscreen and
front side windows.
If your vehicle is fitted with additional
heating, switch it off to ensure rapid and
effective demisting/defrosting.
ADDITIONAL REAR VENTILATION


The controls for this system,
additional to the standard cabin
ventilation system, are on the
lower dashboard, to the right of
the steering wheel.

REAR HEATING AND/OR AIR
CONDITIONING
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 fl oor, 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.

The first press activates (LED on).
A second press deactivates (LED off). To deactivate the blower, place the control in
position 0. However, a safety device will ventilate the
rear circuit automatically, even if the control
is in position 0, to prevent the formation of
condensation.
