Interior Mirror
Vehicles with a manual rearview mirror can be adjusted to see clearly behind the vehicle. Hold the mirror in the center to move it up or down and side to side. To reduce headlamp glare during nighttime use, push the tab forward for daytime use and pull it for nighttime use.
Vehicles with the automatic dimming feature will automatically reduce the glare of headlamps from behind the vehicle. The dimming feature comes on and the indicator light illuminates each time the vehicle is started.
See Automatic Dimming Rearview Mirror on page 2‑17 for more information.
