• Automatic air conditioning manual settings

Adjusting the temperature

The driver and front passenger can each choose their own temperature setting.

The value indicated corresponds to a level of comfort and not to a precise temperature.

► Turn the knob 1 or 2 of the central controls to increase (red) or decrease (blue) the value.

It is recommended that you avoid a difference of more than 3ºC in the settings for left and right.

Temperature synchronisation

The driver side temperature setting is applied to the passenger side.

► Press button 10 to activate/deactivate the function.

The function is automatically deactivated if the passenger uses their temperature adjustment buttons.

Automatic air conditioning

This automatic mode ensures optimum management of the passenger compartment temperature, air flow and air distribution, based on the selected comfort level.

► Press knob 3 of the central controls to activate or deactivate the air conditioning system's automatic mode.

The indicator lamp in the button lights up when the air conditioning system is operating automatically.

The intensity of the automatic air conditioning is modulated by choosing one of the following settings:

- AUTO SOFT: provides soft and quiet operation by limiting air flow.

- AUTO NORMAL: offers the best compromise between a comfortable temperature and quiet operation (default setting).

- AUTO FAST: provides dynamic and efficient air distribution.

To change the AUTO mode, press button 9 successively.

To ensure passenger comfort in the rear seats, favour settings AUTO NORMAL and AUTO FAST.

In cold weather with the engine cold, the air flow is increased gradually until the comfort setting has been reached, in order to limit the delivery of cold air into the passenger compartment.

On entering the vehicle, if the interior temperature is much colder or warmer than the comfort setting requested, there is no need to alter the value displayed to more quickly reach the required level of comfort. The system automatically corrects the temperature difference as quickly as possible.

Automatic air conditioning manual settings

It is possible to manually adjust one or more of these functions, while the system retains automatic control of the other functions:

- air flow.

- air distribution.

The indicator lamp in the "AUTO" button goes out if a setting is changed.

► Press knob 3 again to reactivate automatic air conditioning.

Adjusting the air flow

► Turn the knob 3 to increase of decrease air flow.

Switching off the air conditioning system

When the air flow is reduced to a minimum, ventilation stops.

"OFF" is displayed and the lights on the central controls go off.

Adjusting the air distribution

► Press the buttons 8 to adjust the air flow distribution inside the passenger compartment.

Windscreen and side windows

Central and side air vents

Footwells

A symbol is activated to display the presence of blown air in the direction indicated.

It is possible to activate all three buttons simultaneously, for uniform distribution throughout the passenger compartment.

Air conditioning on / off

The air conditioning is designed to operate effectively in all seasons, with the windows closed.

It lowers the temperature in summer.

It increases the effectiveness of demisting in winter, above 3ºC.

► Press knob 1 to switch the air conditioning on/off.

When the system is activated, the indicator lamp of the button comes on.

Air conditioning does not operate when the air flow is deactivated.

Switching off air conditioning may result in some discomfort (humidity, misting).

Maximum air conditioning

This function automatically adjusts the temperature setting to the lowest possible, the air distribution towards the central and side air vents, the air flow to maximum and activates interior air recirculation.

► Press knob 2 to activate/deactivate the function (confirmed by the indicator lamp coming on/switching off).

Once the function is deactivated, the system returns to the previous settings.
