Auto-Dimming Mirror Inspection

WARNING: This page is about a different car, the 2004 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.
  1. Cover the day/night sensor on the back of the mirror with a piece of black paper or cloth.
  2. In a well-lit area, shine a light at the mirror to simulate glare from vehicles to the rear. Verify that the mirror dims automatically.
NOTE:
  • The mirror will dim within 2 min  if testing for the first time.
