Dual-zone

Citroën C5 / Citroen C5 Owner's Manual / Comfort / Automatic air conditioning / Dual-zone

The dual-zone system regulates the temperature and air distribution for the drivers's side and the passenger's side independently. The air flow is common to both sides.

3a Adjustment of air distribution on driver's side
3b Adjustment of air distribution on passenger's side
4a Driver's side display
4b Passenger's side display
5 Adjusting the air flow
6 Activation/deactivation of air conditioning
7 Air recirculation Entry of air from outside
8 Rear demisting - deicing
9 Front demisting - deicing

1a-1b. Automatic operation

1a-1b. Automatic operation

This is the normal operating mode for the system.

This is the normal operating mode for the system.

Depending on the level of comfort chosen, a press on this button, confirmed by light A coming on, allows all of the following functions to be automatically and simultaneously controlled:

Air flow.

Cabin temperature.

Air distribution.

Air conditioning.

Automatic air recirculation

It is recommended to keep all the air vents open. Just by pressing any of the buttons, except for temperature 1a and 1b, you can change to manual mode. The light A goes out.

2a-2b. Temperature adjustment

Turn control 2a to change the driver's side temperature and control 2b to change

Turn control 2a to change the driver's side temperature and control 2b to change the passenger's side temperature:

Clockwise to increase the temperature.

Anti-clockwise to reduce the temperature.

The chosen temperature is displayed.

An adjustment around 21 will give you the optimum comfort level.

However, depending on your preferences anywhere between 18 and 24 is quite usual.

Operating the air conditioning system 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 retaining the other functions in automatic mode.

Press on any of the buttons, except for temperature 2a and 2b. Lights A on 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 optimum comfort.

To return to AUTO mode, press on buttons 1a and 1b. Lights A come on.

3a-3b. Adjusting the air distribution

Press button 3a to change the driver's side air flow distribution.

Press button 3a to change the driver's side air flow distribution.

Press button 3b to change the passenger's side air flow distribution.

The symbol (arrows) corresponding 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 distribution to the windscreen/front windows and to the front/rear air vents at the same time.

4. Adjusting the air flow

The air flow can only be adjusted with the engine running.

To adjust the air flow, press button:

to reduce the air flow to increase the air flow

The air flow level is indicated by the progressive lighting of the ventilatorto reduce the air flow

The air flow level is indicated by the progressive lighting of the ventilator blades.

By reducing the air flow to its minimum setting, the air conditioning system switches itself off (OFF).

To prevent misting and poor air quality in the passenger compartment, take care to maintain a sufficient flow of air.

5. Air conditioning

Air conditioning only works with the engine running.

Air conditioning only works with the engine running.

The air blower button (air flow adjustment) must be activated to obtain air conditioning.

Press on button 6. The warning lamp comes on.

To function efficiently, air conditioning should be used with the windows closed.

6. Air recirculation Entry of air from outside

This button activates the recirculation of air in the passenger compartment and

This button activates the recirculation of air in the passenger compartment and can function automatically.

Entry of air in automatic anti-pollution mode activated by default, in automatic comfort regulation.

Automatic mode uses an air quality sensor. This analyses the air and isolates

Automatic mode uses an air quality sensor. This analyses the air and isolates the passenger compartment from the exterior, as soon as it detects the presence of pollutants. In this case, it automatically activates recirculation of passenger compartment air.

Remark: this function cannot detect and therefore protect the passenger compartment from bad smells not linked to pollutants. It is not active when the outside temperature is below +5C in order to protect against the risk of misting.

Switching off the entry of air

Press button 6 to switch off the entry of air from outside.

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 unpleasant smells or smoke/emissions coming from outside.

This mode should be cancelled as soon as possible to allow the redistribution of air in the passenger compartment.

Entry of air from outside

Press once on button 6 to return to the original status (Entry of air from outside).

Press once on button 6 to return to the original status (Entry of air from outside).

7. R ear demisting - deicing

Press button 7, with the engine running, to start a rapid deicing or demisting

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 temperature.

It can be interrupted by a further press on button 7 or by stopping the engine.

In the latter case, demisting will resume when the engine is switched on again.

Note: The heated rear screen operates independently of the automatic air conditioning.

8. Front demisting - deicing

In some cases, AUTO mode may not be sufficient to demist or defrost the windows

In some cases, AUTO mode may not be sufficient to demist or defrost the windows (e.g. humidity, several passengers, frost).

Press button 8 for rapid clear windows.

The warning lamp comes on. This system controls air conditioning, temperature and air flow/entry. It distributes ventilation towards the windscreen and the front windows.

You can manually exit Demisting mode. This mode should be cancelled as soon as possible to allow the redistribution of air in the passenger compartment.

A press on either of the buttons 1a or 1b allows you to return to AUTO mode.

Remarks: When starting from cold, in order to prevent unwanted cold air, the air flow 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 temperature that is displayed as an attempt to go immediately to the desired comfort level. The system automatically uses all of its power to compensate the temperature gap as quickly as possible.

Water arising from the condensation in the air conditioning drains out through a hole provided for this purpose ; a pool of water may thus form underneath the vehicle when stationary.

Whatever the time of year, even in cool weather the air conditioning is useful in removing humidity and misting. Avoid driving for too long with air conditioning deactivated.
