Mirrors
Electrochromic Day/Night Rearview Mirror
This mirror automatically changes to reduce glare from
the 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 glare is reduced.
Cleaning Photocells
Use a cotton swab and glass cleaner to clean the front
and rear photocells that make the auto

Time Delay
This feature prevents rapid changing of the mirror from
the night mode to the day mode as you drive under
lights and through traffic.
