What automatic air recirculation does
In automatic air recirculation mode, fresh air will enter the passenger compartment. If the system
detects an increased concentration of pollutants in the outside air, it automatically switches to air
recirculation. As soon as the pollutant level is back in the normal range, air recirculation is switched
off.
Unpleasant odors cannot be detected by the system.
To keep the windows from fogging up, automatic air recirculation is not switched on automatically in
certain circumstances.
.WARNING
Stale air causes driver fatigue and reduces driver alertness, which can cause accidents,
collisions and serious personal injury.
x Never use air recirculation mode over an extended period of time, since no fresh air will
enter the passenger compartment.
x When the air conditioner is off and recirculation mode is on, condensation can quickly
form on the windows and greatly reduce visibility.
x Always switch off recirculation mode when it is not needed.
.NOTICE
Do not smoke when air recirculation is switched on. Smoke drawn into the ventilation system
can leave residue on the evaporator and on the dust and pollen active CARbon filter, resulting
in permanent odors whenever the air conditioner is switched on.
.When backing up and while the automatic wiper/washer is operating, air recirculation is briefly
activated to avoid unpleasant odors in the passenger compartment. This feature only works if
automatic air recirculation is enabled
