174 UNDERSTANDING YOUR INSTRUMENT PANEL the zone, press and release the RESET button to increment the variance one step. Repeat as necessary, until the desired variance is achieved. NOTE: Zone 8 is the factory default. During programming, the Zone Number will wrap around from Zone 15 to 1. Please refer to the Compass Variance Zone Map in the following section: "Electronic Vehicle Information Center (EVIC)" Automatic Compass Calibration The compass on your vehicle is self-calibrating, eliminating the need to manually calibrate the compass. When the vehicle is new, the compass may appear erratic and the CAL indicator message will flash in the EVIC until the calibration is complete. A good calibration requires a level surface and an environment free from large metallic objects such as buildings, bridges, underground cables, railroad tracks, etc. Calibrate the compass by driving slowly, under 5 mph (8 km/h) in one or more complete circles in a area free from large metallic objects, until the CAL indicator in the EVIC turns off. The compass will now function normally. NOTE: Keep all magnetic objects, such as laptop computers, cell phones and Personal Digital Assistants (PDAs) (anything with a battery) away from the compass sensor, which is located in the top of the instrument panel. These devices can interfere with compass accuracy and performance. Manual Compass Calibration If the compass appears erratic or inaccurate, and the variance has been properly set, you may wish to manually recalibrate the compass. To manually calibrate the compass: 1. Start the engine, and leave the transmission shift lever in the PARK position.
