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. 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.

The heating/ventilation or air conditioning systems operates with the engine running, as well as in STOP mode with Stop & Start.


1. Temperature adjustment



)
Turn the dial from blue
(cold) to red (hot) to adjust
the temperature to your
requirements.



2. Air fl ow adjustment



)
Turn the dial from position 1

to position 5
to obtain a
comfortable air flow.

)
If you place the air flow control
in position 0
(deactivation of the
system), the temperature is no
longer maintained at a comfor table
level. However, a slight flow of air,
due to the movement of the vehicle,
can still be felt.



3. Air distribution adjustment

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 avoids the formation of
mist on the windscreen and side windows.
The recirculation of interior air insulates the
passenger compar tment from exterior odours
and smoke.
Return to exterior air intake as soon as possible
to prevent deterioration of the air quality and
the formation of mist.

Manual control panel



)
Move the manual control to
the left to be in the "recycling
interior air" position.

)
Move the manual control to the
right to return to the "fresh air
intake" position.

Digital air conditioning
The air conditioning operates when the engine is running, as well as in STOP mode with Stop & Start.


Automatic operation


1. Automatic "comfort"
programme
Press the "AU TO "
button. The
"AU TO "
symbol is displayed.
We recommend that you use
this mode. It provides optimised
automatic control of all of the following
functions: passenger compar tment
temperature, air flow, air distribution and air
intake, in accordance with the comfort value
that you have chosen.
This system is designed to operate effectively
in all seasons, with the windows closed. For your comfor t, when the engine is
switched off, the settings are retained
until the engine is switched on again.
To prevent too great a distribution of
cold air when the engine is cold, the air
flow will only reach its optimum level
gradually.


2. Temperature adjustment

The value indicated on the display corresponds
to a level of comfor t and not to a temperature in
degrees Celsius or Fahrenheit. On entering the vehicle, if the interior
is very cold or hot, there is no need to
change the value displayed in order
to reach the required level of comfor t.
The system corrects the temperature
difference automatically and as quickly
as possible.
Press the "



"
and "



"
buttons to
change this value. A setting around
the value 21
enables optimum
comfor t to be obtained. However,
depending on your requirements, a
setting between 18 and 24 is usual.

3. Automatic "visibility"
programme

The automatic comfor t programme
may not be sufficient for rapid
demisting or defrosting of the
windscreen and side windows
(humidity, several passengers, ice, etc.).
In this case, select the automatic visibility
programme. The button 3
indicator lamp
comes on.
The system automatically controls the air
conditioning and the flow of air and provides
optimum air distribution to the windscreen and
side windows. It deactivates air recirculation 5
.
To exit this programme, press button 3
again or
"AU TO "
, the indicator lamp on the button goes
off and "AU TO "
is displayed.







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