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 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 digital air conditioning system.


Operate the air conditioning system for at least 5 to 10 minutes, once or twice a month
to keep it in per fect working order.


Ensure that the passenger compartment 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 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.
You can switch off the air conditioning (AC button) and stay in Automatic mode in order
to limit fuel consumption. If misting appears while in this mode, you can switch the air
conditioning back on temporarily to improve the situation.
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.












Recommendations for ventilation and air conditioning


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.

The condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
per fectly normal.


If you want to prioritise heating, start
and leave the engine running by
pressing ECO OFF.

Dual-zone digital air conditioning


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 control the
system, according to the desired setting, while
also maintaining the desired comfort value.


Press the "AUTO "
button repeatedly:


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

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

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

Use the "medium" and "high" settings in
preference to maintain the comfort level at the
rear.
When the engine is cold, the air
flow will reach its optimum level
progressively, taking account of the
weather and the desired comfort level
so as to avoid too great a distribution
of cold air.
On entering the vehicle, if the interior
temperature is much colder or warmer
than the comfort value, there is no
need to change the value displayed in
order to obtain the comfort required. In
all seasons, with the windows closed
the system corrects the difference
in temperature automatically and as
quickly as possible.
This system is designed to operate effectively
in all seasons, with the windows closed.

4. Automatic visibility
programme

For maximum cooling or heating of the
passenger compartment, it is possible
to exceed the minimum value 14 or the
maximum value 28.



Turn control 2
or 3
to the left
until "LO"
is displayed or to the
right until "HI"
is displayed.
See "Front demisting - defrosting".



2-3. Driver's-passenger's side
settings
The driver and front passenger can
each adjust the temperature to their
requirements.
The value indicated on the display
corresponds to a level of comfort and not to a
temperature in degrees Celsius or Fahrenheit.



Turn control 2
or 3
to the left or to the right
respectively to decrease or increase this
value.
A setting around the value 21 provides
optimum comfort. However, depending on your
requirements, a setting between 18 and 24 is
normal.
You are advised to avoid a left / right setting
difference of more than 3.


Manual operation

If you wish, you can make a different choice
from that offered by the system by changing a
setting. The "AUTO "
indicator lamps go off; the
other functions, except the air conditioning, will
still be controlled automatically.



Pressing the "AUTO "
button returns the
system to completely automatic operation.






With Stop & Start, when demisting has
been activated, the STOP mode is not
available.

5. Air conditioning On / Off




Press this button to switch off
the air conditioning.
Switching the system off could result in
discomfort (humidity, condensation).



Press this button again to return to
automatic operation of the air conditioning.
The indicator lamp in the "A /C "
button
comes on.
To obtain cool air more quickly, you can
use recirculation of the interior air for a
few moments. Then revert to the intake of
exterior air.


6. Air distribution adjustment




Press one or more buttons to
direct the air flow towards:


- the windscreen and side windows,

- the outer and centre air vents,

- the footwells.

You can combine the three orientations to
obtain the desired air distribution.


7. Air fl ow adjustment




Turn this control to the left to
decrease the air flow or to the
right to increase the air flow.
The air flow indicator lamps, between the two
fans, come on progressively in relation to the
value requested.


8. Air intake / Air recirculation

Air recirculation enables the passenger
compartment to be isolated from exterior odours
and smoke when external pollution is detected
(if your vehicle is fitted with a pollution sensor).
It is activated automatically on operation of the
screenwash.
It is inactive when the ambient temperature is
below 5 °C to avoid the risk of misting in the
vehicle.


- The indicator lamp with "A" on
indicates that recirculation is
controlled automatically.

- The indicator lamp without "A"
on indicates that recirculation
is forced manually.

- Both indicator lamps off
indicates that recirculation is
controlled automatically without
taking account of the detection
of pollution.



Without pollution sensor

If your vehicle is not fitted with a
pollution sensor, press this button
to force recirculation manually.

Switching the system off




Turn the air flow control to the
left until all of the indicator
lamps go off.

Avoid prolonged operation in interior
air recirculation mode or driving for
long periods with the system off (risk of
condensation and deterioration of air
quality). This action switches off the air conditioning and
the ventilation.
Temperature related comfort is no longer
assured but a slight flow of air, due to the
movement of the vehicle, can still be felt.



Modify the settings (temperature, air flow
or air distribution) or press the "AUTO "

button to reactivate the system with the
values set before it was switched off.



9. Maximum air conditioning




If you want to quickly cool
the air in the passenger
compartment, press this
button; "LO"
is displayed.
To return to the previous settings, press the
button again.


Switch off the demisting/defrosting
of the rear screen and door mirrors
as soon as appropriate, as lower
current consumption results in
reduced fuel consumption.

conditioning, air flow and air intake, and
provides optimum distribution towards the
windscreen and side windows.



To stop the programme, press either
the "visibility"
button again or "AUTO "
,
the indicator lamp in the button goes off
and the indicator lamp in the "AUTO "

button comes on.
The system starts again with the values in
use before it was overridden by the visibility
programme.



Press this button (located on
the air conditioning system
control panel) to demist /defrost
the rear screen and the door
mirrors. The indicator lamp
associated with the button
