INTERIOR MIRROR
The interior rear view mirror has two pivot points on the support arm
which lets you adjust the mirror up or down and from side to side.
WARNING:Do not adjust the mirror while the vehicle is in
motion.
Automatic dimming interior rear view mirror
The interior rear view mirror and a driver’s side exterior mirror have an
auto-dimming function. The electronic day/night mirrors will change from
the normal (high reflective) state to the non-glare (darkened) state
when bright lights (glare) reach the interior mirror. When the interior
mirror detects bright light from behind the vehicle, the interior rear view
mirror and the driver’s side exterior mirror will automatically adjust
(darken) to minimize glare.
The mirrors will automatically return to the normal state whenever the
vehicle is placed in R (Reverse) to ensure a bright clear view when
backing up.
Do not block the sensors on the front and back of the interior
rear view mirror since this may impair proper mirror
performance.
Note:A rear center passenger and/or raised rear center headrest (if
equipped) may also block the light from reaching the sensor.
Do not clean the housing or glass of any mirror with harsh
abrasives, fuel or other petroleum-based cleaning products.
