A Word About Cabin Air Filters
For recirculation mode to work effectively for air quality, your cabin air filter needs to be clean. This filter traps pollen, dust, and pollutants before air enters your cabin. Replace it according to your vehicle’s maintenance schedule (usually every 12,000-15,000 miles or once a year).HVAC & Climate Control

Turn it off when windows fog, on long trips, and when you need fresh air.
Once you start using it with intention, you’ll wonder how you ever drove without this simple knowledge.
