driving habits in order to increase fuel economy.
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 EVIC 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 EVIC 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
buildings, bridges, underground cables, railroad tracks,
etc.
Manual Compass Calibration
If the compass appears erratic and the "CAL" indicator
does not appear in the EVIC display, you must put the
compass into the Calibration Mode manually as follows:
1. Start the engine. Leave the shift lever in PARK in order
to enter the EVIC Programming Menus.
2. Press the MENU button until the Personal Settings
(Customer-Programmable Features) menu displays in the
EVIC.
3. Press the SCROLL button until "Calibrate Compass"
displays in the EVIC.
4. Press and release the FUNCTION SELECT button to
start the calibration. The "CAL" indicator will display in
the EVIC.
