Keep in mind the following:
• Make it a rule to have the air quality sensor activated at all times.
• Recirculation is limited in cold climates to avoid fogging.
• If window fogging occurs, you should deactivate the air quality sensor. Also use the defroster functions for the windshield, side windows and rear window.
• 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.
