Mirrors

Manual Rearview Mirror

Pull the tab under the mirror toward you to reduce the
glare from headlamps behind you after dark. Push
the tab away from you for normal daytime operation.

Automatic Dimming Rearview Mirror

If your vehicle has this feature, the mirror automatically
changes to reduce glare from headlamps behind
you. A photocell on the back of the mirror senses when
it is becoming dark outside. Another photocell built
into the mirror surface senses when headlamps
are behind you.
At night, when the glare is too high, the mirror will
gradually darken to reduce glare. This change may take
a few seconds. The mirror will return to its clear
daytime state when the vehicle is put into REVERSE (R)
or when the glare is reduced.
AUTO (Automatic Dimming): This button is located at
the base of the mirror. Use it to turn on the automatic
feature. The button has an indicator light to show it is on.
OFF: Press this button to turn the automatic feature off.
