Inside Automatic Dimming Mirror — If Equipped
This mirror automatically adjusts for annoying headlight
glare from vehicles behind you. You can turn the feature
on or off by pressing the button at the base of the mirror.
A light in the button will indicate when the dimming
feature is activated.
CAUTION!
To avoid damage to the mirror during cleaning,
never spray any cleaning solution directly onto the
mirror. Apply the solution onto a clean cloth and
wipe the mirror clean.
Outside Mirrors
To receive maximum benefit, adjust the outside mirrors
to center on the adjacent lane of traffic with a slight
overlap of the view obtained on the inside mirror.
