Recommendations for ventilation and air conditioning


If after an extended stop in sunshine, the interior temperature is veryhigh, 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 notcontain 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 wellas the air extractor located in the boot. )
Do not cover the sunshine sensor, located on the dashboard; this is used for regulation of the air conditioning system. )
Operate the air conditioning system for at least 5 to 10 minutes, once or twice a monthto keep it in perfect working order. )
Ensure that the passenger compar tment filter is in good condition and have the filter elements replaced regularly. We recommend the use of a combined passenger compar tment filter. Thanks to its special active additive, it contributes to the purification of the air breathed by theoccupants 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 haveit 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 theair conditioning increases the available engine power and so improves the towing ability.

The condensation created by the air conditioning results in a dischargeof water under the vehicle which is perfectly normal.

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 "AUTO"button.The "AUTO"
symbol is displayed. We recommend that you use
this mode. It provides optimisedautomatic 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 effectivelyin all seasons, with the windows closed.
For your comfor t, when the engine isswitched 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
de
grees Celsius or Fahrenheit.
On entering the vehicle, if the interior is very cold or hot, there is no need tochange the value displayed in order to reach the required level of comfort. The system corrects the temperature difference automatically and as quickly as possible.
Pr
ess the ""
and ""
buttons tochange this value. A setting around
the value 21enables optimum comfor t to be obtained. However,
depending on your requirements, asetting between 18 and 24 is usual.
