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 compar tment.
The air conditioning system does not
contain 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 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.
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.
The condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
per fectly normal.




Stop & Start

The heating and air conditioning systems only work when the engine is running. To maintain
a comfortable temperature in the passenger compartment, you can temporarily deactivate
the Stop & Star t 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 compar tment by combining
several air outlets.

)
If you place the air flow control
in position 0
, the system is
deactivated. However, a slight flow
of air, due to the movement of the
vehicle, can still be felt.


)
Turn the dial from position 1
to position 5
to
obtain a comfor table air flow. Windscreen and side windows.
Windscreen, side windows and
footwells.
Footwells.
Central and side vents.
The air distribution can be
adapted by placing the dial in an
intermediate position.

4. Air intake/Air recirculation

The intake of exterior air prevents the formation
of mist on the windscreen and side windows.


)
Press the button to recirculate
the interior air. The indicator
lamp comes on to confirm this. This function allows hot or cold air to be
delivered selectively and more quickly.


5. Air conditioning On/Off

The air conditioning is designed to
operate effectively in all seasons,
with the windows closed.

Switching on



)
Press the "A /C "
button, the button's
indicator lamp comes on.
The air conditioning does not operate
when the air flow adjustment control 2

is in position " 0
". The recirculation of interior air isolates the
passenger compar tment from exterior odours
and smoke.
Return to exterior air intake as soon as possible
to prevent deterioration of the the air quality
and the formation of mist.

)
Press the button again to permit the intake
of exterior air. The indicator lamp goes off
to confirm this.

It enables you to:


- lower the temperature, in summer,

- increase the effectiveness of the demisting
in winter, above 3 °C.



Switching off



)
Press the "A /C "
button again, the button's
indicator lamp goes off.
Switching off may affect comfor t levels
(humidity, condensation).

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 comfor t 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 "AU TO "
button repeatedly:


- a first indicator lamp comes on; the
"light" 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 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 comfor t value, there is no
need to change the value displayed in
order to obtain the comfor t required.
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.

2. Driver's side adjustment
4. Automatic visibility
programme
For maximum cooling or heating of the
passenger compar tment, it is possible
to exceed the minimum value 14 or the
maximum value 28.

3. Passenger's side adjustment

The driver and front passenger can
each adjust the temperature to their
requirements.
The value indicated on the display
corresponds to a level of comfor t 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.

9. "REST" function: ventilation
with the engine off
Even with the engine is off, you can
operate the ventilation for a
few minutes.
Air recirculation enables the passenger
compar tment to be isolated from exterior
odours and smoke.


)
As soon as possible, press this button
again to permit the intake of outside air and
prevent 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.
