Setting Magnetic Zone Variance
Variance is the difference between magnetic North and geographic North. For proper compass function, the correct variance zone must be set.
Refer to the SETTING MAGNETIC ZONE VARIANCE map for the correct zone. Follow these steps to check or change the variance zone:
EVIC:
- The ignition switch must be in the On position and the EVIC display must not be blank.
- If the compass data is not displayed, step through until the compass information displays.
- Press and hold the RESET button (approximately 5 seconds) until VARIANCE = XX is displayed. The EVIC will display the variance zone stored in memory and the word VARIANCE.
- Use the RESET button to select the proper variance zone number, 1 through 15.
- After selecting the proper zone number, momentarily press and release the RESET button. The variance zone is then stored in the memory and the EVIC returns to normal operation.
