Mirror Operation

The right side of the button located at the bottom of the
mirror turns the electrochromic mirror on and off. To
turn on the automatic dimming feature, press MIRROR.
To turn off automatic dimming, press MIRROR again.
The green indicator light will be illuminated when this
feature is active.

Compass Operation

Press the COMPASS button once to turn the compass on
or off.

When the ignition and the compass feature are on, the
compass will show two character boxes for
approximately two seconds. After two seconds, the
mirror will display the compass heading.

If, after two seconds, the display does not show a
compass heading (“N” for North, for example), there
may be a strong magnetic field interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, magnetic note pad holder or a
similar magnetic item.

Compass Calibration

If the letter “C” should ever appear in the compass
window, the mirror may need calibration.

The mirror can be calibrated in one of two ways:

D

Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display reads a direction, or

D

Drive the vehicle on your everyday routine.

Compass Variance

The mirror is set in zone eight upon leaving the factory.
It will be necessary to adjust the compass to compensate
for compass variance if you live outside zone eight.
Under certain circumstances, as during a long distance
cross

-

country trip, it will be necessary to adjust for

compass variance. Compass variance is the difference
between earth’s magnetic north and true geographic
north. If not adjusted to account for compass variance,
your compass could give false readings.
