2. Turn the ignition switch to the ON position. If the compass/temperature data is not currently being displayed, momentarily depress and release the
Step push button to step through the display options until you have reached the compass/temperature display.
3. Depress both the U.S./Metric and the Step push buttons at the same time and hold them down for more than 100 milliseconds, but not more than
one second. The compass mini-trip computer will enter the variation adjustment mode and "VAR" along with the current variance zone will
appear in the display.
4. Within the next five seconds, momentarily depress and release the U.S./Metric push button. The variance zone will automatically be set in the
compass mini-trip computer module memory and normal operation will resume.
5. If the "VAR" in the display flashes twice before the compass mini-trip computer module resumes normal operation, the new variance zone setting
was not accepted. Reorient the vehicle so it is headed within 45 degrees of north or south and repeat this procedure.
