Automatic Dimming Mirror — If Equipped
A single ball joint mirror is provided in the vehicle. It is
a twist on mirror that has a fixed position at the wind-
shield. The mirror installs on the windshield button with
a counterclockwise rotation and requires no tools for
mounting. The mirror head can be adjusted up, down,
left, and right for various drivers. The mirror should be
adjusted to center on the view through the rear window.
This mirror automatically adjusts for headlight glare
from vehicles behind you.
NOTE: This feature is disabled when the vehicle is in
reverse gear to improve rear view viewing.
