138 GETTING TO KNOW YOUR INSTRUMENT PANEL
Automatic Compass Calibration
This compass is self-calibrating, which eliminates the need
to set the compass manually. When the vehicle is new, the
compass may appear erratic, and the instrument cluster
display will display "CAL" until the compass is calibrated.
You may also calibrate the compass by completing one or
more 360–degree turns (in an area free from large metal or
metallic objects) until the "CAL" message displayed in the
instrument cluster display turns off. The compass will now
function normally.
NOTE: A good calibration requires a level surface and an
environment free from large metallic objects such as build-
ings, bridges, underground cables, railroad tracks, etc.
Manual Compass Calibration
If the compass appears erratic and the CAL indicator does
not appear in the instrument cluster display, you must put
the compass into the Calibration Mode manually, as fol-
lows:
1. Turn ON the ignition switch.
2. Push and release the up or down arrow button until the
System Setup (Customer-Programmable Features) menu
is reached, then push and release the right arrow button.
3. Push and release the down button until "Calibrate
Compass" is displayed in the instrument cluster display
then push and release the right button.
4. Push and release the right button to start the calibration.
The "CAL" indicator will be displayed in the instrument
cluster display.
5. Complete one or more 360–degree turns (in an area free
from large metal or metallic objects) until the "CAL"
indicator turns off. The compass will now function
normally.
Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly set,
the compass will automatically compensate for the differ-
ences, and provide the most accurate compass heading. For
the most accurate compass performance, the compass must
be set using the following steps.
