Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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:
- The ignition switch must be in the ON position and the Compass/Temperature Module display must not be blank.
- Depress and hold the STEP button for 5 - 10 seconds until ZONE appears in the display, then release the STEP button. The number displayed is the variance zone currently stored in the compass memory.
- To change the zone, depress the STEP button to scroll through the zone numbers 1 through 15, until the desired zone is displayed.
- After selecting the zone, wait approximately 15 seconds until the display returns to normal.
