turns in an area free from large metal or metallic objects,
the “CAL” symbol will turn off and the compass will
function normally.
Manual Compass Calibration
If the compass appears erratic and the “CAL” symbol
does not appear, you must put the compass into the
Calibration Mode manually.
To put into a Calibration Mode: Turn on the ignition
switch and set the display to Comp/Temp. Press the
RESET button on vehicles equipped with a Compass/
Mini Trip Computer for at least 10 seconds until the
“CAL” symbol appears. On vehicles equipped with
Compass/Temp press and hold the C/T and US/M
buttons for 10 seconds. Release the RESET button and
complete three 360° turns in an area free from large metal
objects. The “CAL” symbol will turn off and the compass
will function normally.
CAUTION!
Do not place any external magnets, such as magnetic
roof mount antennas, in the vicinity of the compass.
Do not use magnetic tools when servicing the over-
head console.
Compass Variance
Compass Variance is the difference between magnetic
North and Geographic North. In some areas of the
country, the difference between magnetic and geographic
North is great enough to cause the compass to give false
readings. If this occurs, the compass variance must be set.
NOTE: Magnetic materials should be kept away from
the overhead console.
