of the driver outside mirror. It can show objects that may be in the vehicle's blind
zone.
Driving with the Blind Spot Mirror

Actual Mirror View
When the approaching vehicle is a long distance away, the image in the main
mirror is small and near the inboard edge of the mirror.
As the vehicle gets closer, the image in the main mirror gets larger and
moves outboard.
As the vehicle enters the blind zone, the image transitions from the main
mirror to the blind spot mirror.
When the vehicle is in the blind zone, the image only appears in the blind
spot mirror.
