If the vehicle has this feature, the driver side mirror adjusts for the glare of headlamps behind you. This feature is controlled by the on and off settings on the automatic dimming rearview mirror. See Automatic Dimming Rearview Mirror for more information.
The vehicle may also have a turn signal indicator on the mirror. An arrow on the outside rearview mirror flashes in the direction of the turn or lane change. See Turn and Lane-Change Signals for more information.
If the vehicle has the Side Blind Zone Alert (SBZA) system, see Side Blind Zone Alert (SBZA).
