You are advised to use the auto-matic air conditioning regulation. This automatically regulates the following functions for maximum comfort : air fl ow, passenger com-partment temperature, and air dis-tribution, using different sensors (external temperature, sunlight). This avoids the need to alter any of the settings, with the exception of the temperature displayed.
Take care not to obstruct the sun-light sensor A.
Provided you retain automatic mode (by pressing button “AUTO”) and all the air vents are open, you will maintain an optimum comfort level, also removing humidity and misting, whatever the ambient cli-matic conditions.
The temperature inside the cabin cannot be lower than the tempera-ture outside if the air conditioning is not operating.
To be effective, the air conditioning should only be used with the win-dows closed. If after a lengthy stop in bright sunlight the interior tem-perature is excessive, air the pas-senger compartment by opening the windows for a few moments, then close them again.
Air circulation
For your comfort we advise you to maintain a proper distribution of air within the cabin, both at the front and at the rear.
To obtain an even distribution of air, ensure that you do not obstruct the external air inlet grille located at the base of the windscreen, the air vents, the air outlets on the fl oor underneath the front seats, and the air extractor located behind the fl aps in the boot.
The front and rear air vents are fi t-ted with control knobs which allow you to control and direct the air fl ow. It is recommended to keep all the air vents open.
Dust/pollen fi lter
There is a fi lter for excluding pollen and dust.
This fi lter has to be changed accord-ing to the vehicle maintenance sched-ule. See “Maintenance Guide”.
To ensure the correct operation of the air conditioning system, it is essential to operate the air condi-tioning at least once a month.
The air conditioning operates by using power from the engine. This results in a slight increase in fuel consumption.
In certain extreme operating con-ditions (e.g. carrying a full load up a steep gradient in high tempera-tures), the switching off of the air conditioning allows more power to be transferred to the engine, thereby increasing 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.
If washing the vehicle with a high pressure jet, avoid targeting the air inlet zone.

Operating the air conditioning sys-tem on “AUTO” guarantees good ventilation inside the cabin.Note: The value indicated on the display corresponds to a comfort level and not to a temperature in Celsius or Fahrenheit.
Manual mode
One or more functions can be adjusted manually, while still retain-ing the other functions in automatic mode.
Press on any of the buttons, except for temperature 2a and 2b. Lights Aon buttons “AUTO” go out.
Changing to manual mode may result in a decrease in comfort level (temperature, humidity, smell, misting) and is not advised for opti-mum comfort.
To return to “AUTO” mode, press on buttons 1a and 1b. Lights Acome on.
3a-3b. Adjusting the air distribution
Press but-ton 3a to change the driver's side air fl ow distribu-tion.
-
The air fl ow level is indicated by the progressive lighting of the ventilator blades.
By reducing the air fl ow to its mini-mum setting, the air conditioning system switches itself off (OFF).
To prevent misting and poor air qual-ity in the passenger compartment, take care to maintain a suffi cient fl ow of air.
4. Adjusting the air fl ow
The air fl ow can only be adjusted with the engine running.
To adjust the air fl ow, press button:
to increase the air fl ow
to reduce the air fl ow
5. Air conditioning
Air conditioning only works with the engine running. The air blower button (air fl ow adjustment) must be activated to obtain air conditioning.Press on button 6. The warning lamp comes on.To function effi ciently, air conditioning should be used with the windows closed.
This button activates the recirculation of air in the passenger compart-ment and can function automatically.
6. Air recirculation – Entry of air from outside
Press button 3b to change the passenger's side air fl ow distri-bution.
The symbol (arrows) correspond-ing to the chosen distribution lights up:Windscreen and front windows.Front air vents (central, side and soft diffusion grille if open) and rear air vents.
Front and rear footwells.
Note: You cannot select distribu-tion to the windscreen/front win-dows and to the front/rear air vents at the same time.

Switching off the entry of air
Press button 6 to switch off the entry of air from outside.
Whilst retaining the other settings, this position allows the driver at any moment to exclude unpleas-ant smells or smoke/emissions coming from outside.
This mode should be cancelled as soon as possible to allow the redistribution of air in the pas-senger compartment.
Entry of air from outside
Press once on button 6 to return to the original status (Entry of air from outside).
7. Rear demisting - deicing
Press button 7, with the engine running, to start a rapid deicing or demisting of the rear screen and rear view mirrors. The warning lamp comes on.
This mode automatically stops depending on the outside tempera-ture. It can be interrupted by a fur-ther press on button 7 or by stop-ping the engine.
In some cases, “AUTO” mode may not be suf-fi cient to demist or defrost the windows (e.g. humidity, several passengers, frost).
Press button 8 for rapid clear win-dows. The warning lamp comes on. This system controls air con-ditioning, temperature and air fl ow/entry. It distributes ventilation towards the windscreen and the front windows.
You can manually exit “Demisting” mode. This mode should be can-celled as soon as possible to allow the redistribution of air in the pas-senger compartment.
A press on either of the buttons 1aor 1b allows you to return to “AUTO” mode.
8. Front demisting - deicing
Remarks:
When starting from cold, in order to prevent unwanted cold air, the air fl ow will increase only gradually to its optimum level.
If you enter the vehicle after a fairly prolonged stop and the temperature inside the vehicle is far from comfortable, it serves no purpose to modify the tem-perature that is displayed as an attempt to go immediately to the desired comfort level. The sys-tem automatically uses all of its power to compensate the tem-perature gap as quickly as pos-sible.
Water arising from the conden-sation in the air conditioning drains out through a hole pro-vided for this purpose ; a pool of water may thus form under-neath the vehicle when station-ary.
Whatever the time of year, even in cool weather the air condition-ing is useful in removing humid-ity and misting. Avoid driving for too long with air conditioning deactivated.

Traffi c Announcements (TA) is displayed. I do not receive any traffi c informa-tion or public announce-ments.
The particular radio station is not in the regional traffi c information network.Change to a radio station that does broadcast traffi c information.
The reception quality of the radio station being lis-tened to gradually deterio-rates.
The vehicle is too distant from the transmit-ter, or no transmitter is present in the geo-graphical area you are passing through.
Activate the RDS function to allow the system to check whether a more pow-erful transmitter is to be found in the geographical area.
The environment (hills, high buildings, tun-nels, underground car parks, etc.) is blocking reception, even in RDS mode.
This phenomenon is normal and does not imply anything wrong with the radio.
The aerial is absent or has been damaged (for example after going through a car wash or in an underground car park).
Have the aerial checked by a CITROËN dealer.
Cutting out of sound for 1 to 2 seconds in radio mode.
The RDS system during this brief sound cut-off is searching for a better frequency that might offer improved reception of the station.
Deactivate the RDS function if the phe-nomenon occurs too frequently and always on the same journey.
When the engine is not running, the radio stops after a few minutes.
When the engine is switched off, the work-ing time for the radio depends on the battery charge. The interruption is normal: the radio goes into economy mode, cutting off in order to save the vehicle’s battery.
You have to start the engine so as to increase the battery charge.
The message “the audio system is overheating” appears on the screen.
In order to protect the audio equipment in excessive ambient temperatures, the radio goes into an automatic thermic protection mode which results in a reduction in sound volume or stopping of the CD player.
Switch off the audio system for a few minutes in order to allow the system to cool down.
