DS 3: Ease of use and comfort / Automatic air conditioning

The air conditioning operates with the engine running, but the ventilation and its controls can be accessed with the ignition on.

Operation of the air conditioning and regulation of temperature, air flow and air distribution in the passenger compartment are automatic.

Press the Climate menu button to access the system controls.

Temperature adjustment

• Press one of the buttons 1 to increase (red) or decrease (blue) the value.

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

Adjusting the air flow

• Press one of the buttons 2 (- or +) to increase or decrease 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 3 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 all three buttons simultaneously, for uniform distribution throughout the passenger compartment.

Air conditioning on/off

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

It is used to:

• lower the temperature in summer,
• increase the effectiveness of the demisting in winter, above 3°C.

• Press button 4 to activate/deactivate the air conditioning system.

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

To obtain cool air more quickly, enable interior air recirculation for a brief period. Then return to the intake of exterior air.

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

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 button 5 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.

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 8 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.

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 button 6 to activate/deactivate the function (the indicator lamp will come on/switch off).

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

Switching off the air conditioning system

• Press this button.

Its indicator lamp comes on and all of the other indicator lamps for the system go off.

This action deactivates all of the functions of the air conditioning system.

The temperature is no longer regulated. A slight flow of air can still be felt, due to the forward movement of the vehicle.

Interior air recirculation

The intake of exterior air prevents the formation of mist on the windscreen and side windows.

Recirculating the interior air isolates the passenger compartment from outside odours and fumes and allows the desired passenger compartment temperature to be achieved more rapidly.

• Press this button to activate/ deactivate the function (confirmed by the illumination/extinction of the indicator lamp).

This function is activated automatically when reverse gear is engaged.
