2010 Citroen DS3 air conditioning

67Comfort
Digital air conditioning
The air conditioning operates when the engine is r unning, 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 optimised automatic control of all of the following functions: passenger compar tment temperature, air flow, air distribution and air intake, in accordance with the comfor t 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 "AUTO" , the indicator lamp on the button goes off and "AUTO" is displayed.
With Stop & Star t, when demisting has been activated, the STOP mode is not available.

It is possible to adjust one or more functions manually while leaving the other functions in automatic mode.
The "AUTO" symbol switches off. To return to automatic mode, press the "AUTO"button.

4. Air conditioning on/off
For maximum cooling or heating of the cabin, it is possible to go beyond the minimum 14 or maximum 28 values.  Press the blue button 2 until "LO"is displayed or the red button 2until "HI" is displayed.
Press this button to switch off the air conditioning. Stopping the air conditioning may cause some problems (humidity, misting). Automatic operation of the air conditioning is resumed when the button is pressed again. The symbol "A /C" is displayed.
5. Air intake/Air recirculation
Press this button for recirculation of the interior air. The air recirculation symbol 5 is displayed.
Air recirculation enables the passenger compar tment to be isolated from exterior odours and smoke. Press this button again or press the "AUTO"button to resume automatic management of the intake of air. The air recirculation symbol 5goes off.
Avoid prolonged recirculation of interior air (risk of condensation or deterioration of the air quality).
Switching to manual mode may not be suitable (temperature, humidity, odour, condensation) and does not provide optimum comfor t.

6. Air distribution adjustment
Pressing this button several times in succession enables the air flow to be directed in turn towards:
- the windscreen and the side windows (demisting or defrosting), - the windscreen, side windows and air vents, - the windscreen, the side windows, the air vents and the footwells, - the windscreen, the side windows and the footwells, - the footwells, - the air vents and the footwells, - the air vents.
Avoid driving for long periods with the air conditioning switched off (risk of misting and reduction of the air quality in the cabin).
Press the "full fan" button to increase the air flow.
7. Air fl ow adjustment
The air flow symbol, the fan, fills progressively according to the value requested.
Press the "empty fan" button to decrease the air flow.
Switching the system off
Press the air flow "empty fan"button 7 until the fan symbol disappears.
This action switches off all of the functions of the air conditioning system. Thermal comfor t is no longer controlled. A slight flow of air resulting from the movement of the vehicle, remains perceptible however. Pressing the air flow "full fan" button 7 or on "AUTO" reactivates the system with the values set before it was switched off.

Rear screen demist - defrost
The control button is located on the heating or air conditioning system control panel.
Switching on
The rear screen demisting/defrosting can only operate when the engine is running.  Press this button to demist /defrost the rear screen and (depending on version) the door mirrors. The indicator lamp associated with the button comes on.
Switching off
The demisting/defrosting switches off automatically to prevent an excessive consumption of current.  It is possible to stop the demisting/defrosting operation before it is switched off automatically by pressing the button again. The indicator lamp associated with the button switches off.  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.
If the engine is switched off before the demisting/defrosting is switched off automatically, demisting/defrosting will resume next time the engine is switched on.

Checks
Battery Air filter and passenger compartment filter
Oil filter
Particle emission filter (Diesel)
Following prolonged operation of the vehicle at very low speed or at idle, you may, in exceptional circumstances,
notice the emission of water vapour at the exhaust on acceleration. This does not affect the behaviour of the vehicle or the environment.
Unless other wise indicated, check these components in accordance with the Maintenance and Warranty Guide and according to your engine. Other wise, have them checked by a CITROËN dealer.
The battery does not require any maintenance. However, check that the terminals are clean and correctly tightened, particularly in summer and winter. When carrying out work on the battery, refer to the "Practical information" section for details of the precautions to be taken before disconnecting the battery and following its reconnection.
Refer to the Maintenance and Warranty Guide for details of the replacement inter vals for these components. Depending on the environment (e.g. dusty atmosphere) and the use of the vehicle (e.g. city driving), replace them twice as often if necessar y (refer to the "Engines" section). A clogged passenger compar tment filter may have an adverse effect on the per formance of the air conditioning system and generate undesirable odours.
Replace the oil filter each time the engine oil is changed.
Refer to the Maintenance and Warranty Guide for details of the replacement inter val for this component.
The presence of this label, in par ticular with the Stop & Star t system, indicates the use of a specific 12 V lead-acid battery with special technology and specification, for which the involvement of a CITROËN dealer is required when replacing or disconnecting the battery. Failure to obser ve this recommendation may cause premature wear of the battery.
It is imperative that the maintenance of the par ticle emission filter is carried out by a CITROËN dealer.
