Controls and features
With the ignition key in the OFF, ACC or RUN position, the reading lamp
on the dome lamp can be turned on by pressing the control.
AUTOMATIC DIMMING INSIDE REAR VIEW MIRROR
Your vehicle is equipped with an inside rear view mirror which has an
auto-dimming function. The electronic day/night mirror will change from
the normal state to the non-glare state when bright lights (glare) reach
the mirror. When the mirror detects bright light from front or behind, it
will automatically adjust (darken) to minimize glare.
Do not block the sensor on the backside of the mirror since this may
impair proper mirror performance.
Ensure the mirror is pulled down
low enough to prevent visibility
interference with the overhead
console. The mirror support arm has

two pivot points which lets you
adjust the mirror UP or DOWN and
from SIDE to SIDE.
Press the control to turn the mirror
on or off.
The mirror will automatically return to the normal state whenever the
vehicle is placed in R (Reverse)(when the mirror is on) to ensure a
bright clear view when backing up.
ELECTRONIC COMPASS (IF EQUIPPED)
The compass reading will remain accurate during most driving
conditions. Unknown to the driver, the compass is continuously
recalibrating due to magnetic fields and subtle, slow changes in vehicle
magnetics which can occur over the life of the vehicle.
The compass reading will remain fixed when significant levels are
experienced (such as steel bridges). The compass will return to normal
operation upon leaving the magnetized area.
If highly magnetized items (such as magnetic mount antennas) are
placed very near the compass the display will change to "C" for 15
seconds, then display all segments until the magnetized item is removed.
If a "C" is displayed, refer to Compass calibration adjustment.
Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is four
