Features and controls
NOTE
The electronic compass may not show the correct direc-
tion in the following places where the earth's magnetic
field is disrupted.
In these cases, the correct direction will be displayed once
the vehicle returns to a place where the earth's magnetic
field is stable.
• Vehicle in tunnels or parked in buildings
• Expressways, near railroads, underneath railroad cables,
or over subways
• Near transformer stations or high voltage power lines
Do not attach ski racks, antennas, or any other object to
the vehicle by means of a magnet.

Such magnets will affect the operation of the electronic
compass.

Compass variance
Under certain circumstances, as during a long distance cross-
country trip, it will be necessary to adjust for compass vari-
ance.
Compass variance is the difference between the earth's mag-
netic north and the true geographic north. If not adjusted to
account for this compass variance, your compass could give
false readings.
Refer to "Compass zone code setting" on page 3-131.
Compass direction adjustment
This compass is self-calibrating, which means it automatically
makes corrections against magnetization of its components
when the vehicle is running. It should not be necessary to man-
ually calibrate the compass. If the indicated direction appears
to be wrong, first check the compass variance.
If the compass variance is correct, but the compass still shows
the wrong direction, calibrate the compass as described.
Refer to "Compass calibration" on page 3-133.
