Air conditioning
We recommend use of the automatic
regulation of the air conditioning.
It permits automatic and optimised
control of all of the following functions:
air fl ow, temperature in the passenger
compartment and air distribution, by
means of various sensors (ambient
temperature, sunshine). This elimi-
nates any need for you to change your
settings other than the temperature
value displayed.

 Take care not to cover the sun-
shine sensor A .
If you select the automatic mode (by
pressing the "AUTO" control) and leave
all of the vents open, optimum comfort
will be maintained and humidity and
condensation will be removed regard-
less of the exterior climatic conditions.
The temperature in the passenger
compartment can only be lower than
the ambient temperature if the air
conditioning is on.
HEATING, VENTILATION AND AIR CONDITIONING RECOMMENDATIONS
In order to be effective, the air condi-
tioning must be used with the windows
closed. If the vehicle has been parked
in the sun for a long period and the
interior temperature is very high, fi rst
ventilate the passenger compartment
with the windows open for a few min-
utes, then close the windows.
To keep the air conditioning system
in good working order it is essential
that it is operated at least once a
month.
The air conditioning uses engine power
during its operation. As a result, the fuel
consumption of the vehicle increases.
In certain cases of particularly ardu-
ous use (e.g. towing the maximum
load on a steep gradient in high
temperatures), switching off the air
conditioning saves engine power
and improves the towing capacity.
Air inlet
Check that the exterior grille for the
air inlet, at the bottom of the wind-
screen, is clean and free of dead
leaves, snow, etc.
When washing the vehicle using a
high pressure nozzle, avoid spraying
at the air inlet. Air circulation
Maximum comfort is obtained by
means of a good distribution of air in
the passenger compartment, both in
the front and in the rear.
To obtain a uniform distribution of
air, take care not to block the ex-
terior air intake grille located at the
base of the windscreen, the vents,
the air outlets under the front seats
and the air extractor located behind
the fl aps in the boot.
The front and rear vents are fi tted
with thumbwheels to adjust the air
fl ow and direction. We recommend
that you leave all of the vents open.
Dust filter/Odour filter
(active carbon)
There is a fi lter for excluding odours
and dust.
This fi lter must be changed in line
with the vehicle's servicing schedule
(see: "Maintenance and Warranty
Guide").

PROGRAMMABLE HEATING
The programmable heating operates
independently of the engine.
When the engine is off, it pre-heats
the coolant circuit in order to benefi t
from an optimum engine operating
temperature from the time the en-
gine is switched on.
The programmable heating system
is switched on using the long range
remote control. Activation can be im-
mediate or deferred by means of a
programming function. Programming remote control
The heating system programming
remote control consists of the fol-
lowing buttons and displays:

1. Scrolling functions menu buttons.

2. Function indicator lights: clock,
temperature, operating time, pro-
grammed time, heater operation,
heating management symbols.

3. Digital displays: time, tempera-
ture, duration of operation, pro-
grammed time or level of heating.

4. Off button.

5. On button.
Displays on the remote
control screen Press the buttons
1 in succession to
display the functions.
The fi rst press of the left-hand or
right-hand button displays the time.
Next, the left-hand button permits ac-
cess to the programming time then to
the level of heating (C1 to C5).
The right-hand button permits ac-
cess to the passenger compartment
temperature then to the duration of
operation of the heater if it is to be
switched on immediately.

If a malfunction of the program-
mable heating system occurs,
contact a CITROËN dealer. Displaying the functions
The passenger compartment
temperature information is only
available when the engine is off.
