Automatic Dimming Mirror

If the vehicle has the automatic dimming mirror, the driver outside mirror automatically adjusts for the glare of the headlamps from behind.

This feature is controlled by the on and off setting on the inside rearview mirror. See Automatic Dimming Rearview Mirror on page 2‑20 for more information.
