with a switch located next to the lamp.
The automatic dimming feature is turned on or off by

the mirror face, for up to three seconds. If the button is
pressed and held for five to seven seconds, the compass

Compass Calibration
Press the on/off button for eight seconds to activate
the compass calibration mode. The letter "C" will be
displayed in the compass window of the mirror.
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 indicates 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, such 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.
