Rearview Mirror (If Equipped)

Your vehicle may have an electrochromic day/night
rearview mirror. Push the button in the center of the
mirror to turn this feature on. The mirror will darken
gradually to reduce glare from headlamps behind you.
This may take a few moments.

The mirror’s two outer buttons operate the lights on 
the bottom sides of the mirror.
