• Manual control

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 or press one of the buttons 1 or 2 on the touch screen 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.

Automatic Comfort programme

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 on the central controls or button 10 on the touch screen to activate/ deactivate the air conditioning system's automatic mode.

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

You can adjust the intensity of the Automatic Comfort programme by using the "OPTIONS" button to select one of the available settings:

- "Soft": provides soft and quiet operation by limiting air flow.

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

- "Fast": provides strong and effective air flow.

To change the current setting (shown by the corresponding indicator lamp), press button 14 repeatedly until the desired setting is displayed.

To ensure passenger comfort in the rear seats, favour "Normal" and "Fast" settings.

This setting is associated with automatic mode only. However, on deactivation of AUTO mode, the indicator lamp for the most recently selected setting remains on.

Changing the setting does not reactivate AUTO mode if it was deactivated.

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.

Manual control

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 or button 10 of the touch screen again to reactivate the automatic Comfort programme.

Adjusting the air flow

► Turn the knob 3 or press one of the buttons 3 on the touch screen to increase or decrease the air flow.

The air flow symbol (a fan) is filled in according to the request.

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

"OFF" is displayed alongside the fan.

Adjusting the air distribution

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

Windscreen and side windows

Central and side air vents

Footwells

The lighting of the button indicates that air is being blown in the specified direction.

It is possible to activate the following buttons simultaneously:

- Central and side air vents + footwells

- Windscreen and side windows + footwells

Air conditioning on/off

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

- It lowers the temperature in summer.

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

► Press knob 1 or button 9 on the touch screen to activate/deactivate the air conditioning.

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

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

Switching off the air conditioning may result in some discomfort (humidity or 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.

Mono-zone/Dual-zone

The passenger temperature setting can be linked to the driver's setting (mono-zone function).

► Press button 11 to activate the "MONO" function.

The function is automatically deactivated if the passenger uses their temperature adjustment buttons (dual-zone function).

Ventilation with the ignition on

When the ignition is switched on, you can use the ventilation system to adjust the air flow 2 and air distribution 3 settings in the passenger compartment, for a period which depends on the battery charge.

This function does not allow the operation of the air conditioning system.
