AUTOMATIC DIMMING REAR VIEW MIRRORS (IF EQUIPPED)
Your vehicle is equipped with an inside rear view mirror with 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 inside rear view mirror. When the inside rear view mirror detects
bright light from behind the vehicle, the inside rear view mirror will
automatically adjust (darken) to minimize glare.
Do not block the sensor on the backside of the inside rear view mirror
since this may impair proper system performance.
Press the left button on the mirror
to turn the auto dimming ON or
OFF. The green indicator light left
of the display will illuminate when
this feature is ON.
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.
COMPASS/TEMPERATURE EC MIRROR (IF EQUIPPED)
The compass reading may be affected when you drive near large
buildings, bridges, power lines and powerful broadcast antennas.
Magnetic or metallic objects placed in, on or near the vehicle may also
affect compass accuracy.
Usually, when something affects the compass readings, the compass will
correct itself after a few days of operating your vehicle in normal
conditions. If the compass still appears to be inaccurate, a manual
calibration may be necessary. 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
degrees between adjacent zones and will become noticeable as the
vehicle crosses multiple zones. A correct zone setting will eliminate this
error. Refer to Compass zone adjustment.
