1. Automatic operation

This is the normal operating mode for the system. Depending on the level of comfort

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 inlet.

Air conditioning.

It is recommended to keep all the air vents open.

It is recommended to keep all the air vents open.

You can change to manual mode by pressing on any of the buttons, except button 2.

The light A goes out.

2. Temperature adjustment

Turn control 2 to change the temperature:

Turn control 2 to change the 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 one of the buttons, except the temperature adjustment 2. The light A goes 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 button 1. Light A comes on.

3. Adjusting the air distribution

Press on buttons 3 to change the air flow distribution.

Press on buttons 3 to change the 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. Air conditioning

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 4.

Press on button 4.

Light B comes on.

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

5. Adjusting the air flow

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

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

Turn control 5:

Clockwise to increase the air flow.

Anti-clockwise to reduce the air flow.

The level of air flow is indicated on the control panel display 9 by the progressive filling of the bars.

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.

6. 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 6 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 the 1 button returns you to AUTO mode.

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. Air recirculation Entry of air from outside

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

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

Press button 8 to switch off the entry of air from outside.

The warning lamp comes on.

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.

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.
