Manual inside rearview mirrors can be adjusted by holding in the center to move the mirror for a clearer view of behind the vehicle. Adjust the mirror to avoid glare from the headlamps behind you. Push the tab forward for daytime use and pull it for nighttime use.

See Manual Rearview Mirror on page 2‑17.

Vehicles with an automatic dimming inside rearview mirror can automatically reduce the glare from the headlamps of the vehicle behind you. The dimming feature comes on and the indicator light comes on each time the vehicle is started.
