Safety technology has grown by leaps and bounds in recent years and Subaru's are some of the safest cars and SUVs around. The DriverFocus® Distraction Mitigation System uses a near infrared camera that constantly monitors eye position and head position. It will alert you by beeping if it detects you are distracted or drowsy. This video discusses how it works and turning the system on or off.
Applies to 2020 and newer Forester Touring models.
