Press the COMP switch once briefly 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.
When cleaning the mirror, use
a paper towel or similar
material dampened
with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause the
liquid cleaner to enter the mirror housing.
Compass Calibration
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. If the
letter
“C” should ever appear in the compass window, the
mirror may need calibration.
0 Drive the vehicle in circles at five mph (8 km/hj or
less until the display reads a direction, or
0 Drive the vehicle on your everyday routine.
Compass Variance
The mirror is set in zone eight upon leaving the fictory.
It will be necessary to adjust the compass to compensate
for compass variance
if you live outside zone eight.
Under certain circumstances, as during
it long distance
cross-country trip,
it will be necessary to adjust for
con~pass variance. Compass variance
is the difference
between earth’s magnetic north and true geographic
north.
If not ad-justed to account for compass variance,
your compass could give false readings.
To adjust for compass variance:
1. Use the COMP button located at the bottom of
the mirror.
2. Press and hold the COMP button for three seconds
until a zone number appears in the display.
3. Find your current location and variance zone number
on the following zone map.
