Automatic operation
1. Automatic comfort programme
We recommend the use of one of the three AUTO modes available: they provide optimised regulation of the temperature in the passenger
compar tment according to the comfor t value that you have chosen. These three modes automatically adjust the air flow, according to the desired setting, while also maintaining the desired comfor t value.
 Press the "AUTO" button repeatedly: - a first indicator lamp comes on; the "light" setting mode is selected, - a second indicator lamp comes on; the "medium" setting mode is selected, - a third indicator lamp comes on; the "intense" mode setting is selected.
When the engine is cold, the air flow will reach its optimum level
progressively, taking account of the weather and the desired comfor t level so as to avoid too great a distribution of cold air. On entering the vehicle, if the interior temperature is much colder or warmer than the comfor t value, there is no need to change the value displayed in order to obtain the comfor t required. The system corrects the difference in temperature automatically and as quickly as possible.
This system is designed to operate effectively in all seasons, with the windows closed.

5. Air conditioning On/Off
 Press this button to switch off the air conditioning.
Switching the system off could result in discomfor t (humidity, condensation).  Press this button again to return to automatic operation of the air conditioning. The indicator lamp on the "A /C" button comes on.
6. Air distribution adjustment
 Press one or more buttons to
direct the air flow towards:
- the windscreen and side windows (demisting or defrosting), - the outer and centre air vents, - the footwells. You can combine the three orientations to obtain the desired air distribution.
7. Air fl ow adjustment
 Turn this control to the left to decrease the air flow or to the right to increase the air flow.
8. Air intake/Air recirculation
 Press this button for recirculation
of the interior air. The indicator lamp in the button comes on.
The air flow indicator lamps, between the two fans, come on progressively in relation to the value requested.
9. "REST" function: ventilation with the engine off
Even with the engine is off, you can operate the ventilation for a few minutes.
Air recirculation enables the passenger compar tment to be isolated from exterior odours and smoke.  As soon as possible, press this button again to permit the intake of outside air and prevent the formation of condensation. The indicator lamp in the button goes off.
For example, while you are away from the vehicle, the passengers can still enjoy some air circulation without having the engine running. This function is available after switching on the ignition, as well as after stopping the engine. The period that the function is available depends on the state of charge of the battery. You can activate the "REST" function while the air conditioning control screens are on.
