This feature allows you to monitor when you are
driving in a fuel efficient manner, and it can be
used to modify driving habits in order to in-
crease fuel economy.
Automatic Compass Calibration
This compass is self-calibrating, which elimi-
nates 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
136
objects such as buildings, bridges, under-
ground 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" indi-
cator will display in the EVIC.
5. Complete one or more 360–degree turns (in
an area free from large metal or metallic ob-
jects) 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 differences and provide the most accurate
compass heading.
NOTE:
Magnetic materials should be kept away
from the top of the right rear quarter win-
dow. This is where the compass sensor is
located.
