the engine off
Even with the engine is off, you can
operate the ventilation for a few
minutes.
Air recirculation enables the passenger compartment
to be isolated from exterior odours and smoke.
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.
Avoid prolonged operation in interior air
recirculation mode (risk of misting and
deterioration of air quality).
