Recommended settings
For optimum operation of the manual system, the settings below are recommended:
The diode on the button is off.
This is the preferred operating
position.
The diode on the button is lit.
Recirculation temporarily prevents
exterior odours and smoke
from entering the passenger
compartment.
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 more
quickly with both hot or cold settings.
This position should only be temporary.
When your ambient air comfort level has
been reached, return to the intake of exterior
air position to permit renewal of the air in the
passenger compartment and avoid misting.
This operating mode is preferable. If I require...

AUTOMATIC AIR CONDITIONING WITH SEPARATE ADJUSTMENTS
Good practice
For maximum cooling or heating of the
passenger compartment, it is possible to exceed
the value 15 by turning until LO is displayed or
the value 27 by turning until HI is displayed.
For optimum comfort, the difference between
the value displayed for the driver and for the
passenger should not be greater than 3.
If your vehicle is fitted with this control
panel, it is located on the centre console.
On entering the vehicle, the inside
temperature may be much colder (or
warmer) than is comfortable. There is no
advantage in changing the value displayed
in order to quickly reach the level of comfort
required. The system will use its maximum
performance to reach the comfort value set.

Driver or passenger side comfort value
The value indicated on the display
corresponds to a level of comfort and not a
temperature in degrees Celsius or Fahrenheit. Automatic operation Do not cover the sunshine sensor,
located on the windscreen behind the
mirror, it is used for regulation of the air
conditioning.
AUTO comfort programme
This is the normal air conditioning system
operating mode.
Press this button, the AUTO
symbol is displayed.
In accordance with the comfort
value selected, the system
controls the distribution, the flow
and the intake of air to guarantee comfort
and a sufficient circulation of air in the
passenger compartment. No further action
on your part is required.
When the engine is cold, to prevent an
excessive diffusion of cold air, the ventilation
will reach its optimum level gradually.
For your comfort, the settings are stored
when the ignition is switched off and are
reinstated the next time the vehicle is
started, if the temperature in the passenger
compartment has not changed significantly;
otherwise, operation resumes in automatic
mode. Turn this control to the left or to
the right to decrease or increase
the value. A setting around the
value 21 provides optimum
comfort.However, depending on your
requirements, a setting between 18 and 24
is usual.

Air flow
Press the small fan button to
reduce the flow or the large fan
button to increase the flow.
On the display, the blades of the fan darken
when the flow is increased. Manual operation
You can, according to your requirements,
make a different selection from that offered
by the system by changing a setting.
The other functions will still be controlled
automatically. Pressing the AUTO button
restores fully automatic operation. Intake of exterior air/
Recirculation of interior air
Press this button to recirculate
the interior air. The recirculation
symbol is displayed.
Recirculation prevents exterior odours
and smoke from entering the passenger
compartment. Avoid prolonged operation
in interior air recirculation mode (risk of
condensation, odour and humidity).
Pressing this button again activates the
intake of exterior air.
Air distribution
Pressing this button several times
in succession directs the air flow
towards:
- the windscreen,
- the windscreen and footwells,
- the footwells,
- the side vents, central vents and footwells,
- the side vents and central vents. Deactivating the system
Press the air flow
small fan button
until the fan symbol disappears.
This action deactivates all of the
system's functions, with the exception of the
air recirculation and rear screen demisting
(if fitted on your vehicle). Your comfort
setting is no longer maintained and is
switched off.
For your comfort, do not deactivate the
system for long periods.
Pressing the large fan button or
the AUTO button reactivates the
system with the values set before
it was deactivated. Switching the air conditioning

CORRECT USE OF THE VENTILATION AND AIR CONDITIONING
Vents

"Leave them open"
For optimum distribution and diffusion of hot
or cool air in the passenger compartment,
there are adjustable central and side vents
which can be directed sideways (right or
left) towards the top of the body. For your
comfort while driving, do not close them,
direct the flow of air towards the windows
instead.
The air vents directed towards the floor of
the vehicle complete the equipment.
Passenger compartment filter, carbon filter
Ensure that this fi lter is in good condition and
have all of the fi lter elements replaced regularly.
Refer to the "Checks" section of
chapter 6.
Air conditioning
In all seasons, if fitted on your vehicle, 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, do not hesitate to
ventilate the passenger compartment for a
few minutes. If your vehicle is fitted with automatic
air conditioning, use the AUTO
mode as much as possible as it permits
optimised control of all of the functions:
air flow, passenger compartment comfort
temperature, air distribution, air intake
mode or air recirculation in the passenger
compartment.
Operate the air conditioning system for 5 to
10 minutes, once or twice a month, to keep
it in perfect working order.
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 consult a CITROËN dealer.

Press the air conditioning.
Manual mode

Increase the air flow setting.
DE-ICING AND DEMISTING

in the passenger compartment
(diode off).

distribution setting.

Pressing this button, with the engine
running, activates the rapid demisting -
de-icing of the rear screen and/or electric
mirrors.
This function switches off:
- when the button is pressed,
- when the engine is switched off,
- automatically to prevent excessive energy consumption.
De-icing the rear screen and/or mirrors
Automatic air conditioning: visibility
programme
The comfort programme (AUTO) may not
be sufficient to quickly demist or de-ice the
windows (humidity, several passengers, ice).
In this case, select the visibility programme.
The visibility programme indicator light
comes on.
It activates the air conditioning, the air flow,
the de-icing of the rear screen and provides
optimum distribution of the ventilation to the
windscreen and side windows.
It deactivates the air recirculation.

REAR VENTILATION
If your vehicle is fitted with an additional air
conditioning unit, located in the rear of the
vehicle. The distribution rail located in the
roof and the 6 individualised diffusion vents
provide a perfect diffusion of the ambient air
selected.
The warm air diffused at the floor, from the
front air conditioning unit, is distributed at
the feet of the rear passengers of the
2nd row.
A warm air diffusion vent, located on the
specific unit, completes the assembly for
the feet of the rear passengers of the
3rd row.
Temperature adjustment
Control positioned:
- on the blue, triggers cool air,
- on the red, triggers heating ofthe ambient air.
Activation/Deactivation
Air flow
The force of the blown air, via
the vents, varies from 1 to the
strongest 4.
To obtain a comfortable level of
ambient air, remember to adjust
this control.
To deactivat the blower, place the control in
position 0. This button, located on the
overhead storage unit, enables
you to activate/deactivate the
operation of the rear controls
from the driver's seat or the front passenger
seat.
The first press activates (green diode lit).
A second press deactivates (diode off).

ADDITIONAL HEATING
Vehicles fitted with an HDi engine may be
fitted with a heater. When the engine is at
idle or the vehicle is stationary, it is normal
to notice a high-pitched whistling noise and
a slight emission of smoke and odour.
Rear ventilation
Coolant circuit heater
This is an additional and autonomous
system which heats the diesel engine hot
coolant loop to make starting easier.
It improves the de-icing and demisting
performance.
