Interior air quality sensor (option)
Some vehicles are equipped with a multi-filter and air quality sensor. The filter separates gases and particles,
thereby reducing the amounts of odors and contaminants entering the vehicle. The air quality sensor detects
increased levels of contaminants in the outside air. When the air quality sensor detects contaminated outside air, the
air intake closes and the air inside the passenger compartment is recirculated, i.e. no outside air enters the vehicle.
The filter also cleans recirculated passenger compartment air.
When the ECC system is in the AUTO mode, the green LED will be on .

Recirculation is limited in cold climates to avoid fogging.

If fogging occurs, use the defroster functions for the windshield, side windows and rear window. See page 77 .
●
The filter should be changed at the intervals recommended in the service schedule. However, if the vehicle is
used in a severely contaminated environment, it may be necessary to change the filter more frequently.
