You may also place the compass in a noncalibrated mode by pressing and holding the MODE and US/MET buttons simultaneously while in the COMP/TEMP mode. After about 10 seconds, the compass will display C and you can release the buttons. Drive the vehicle in a complete 360_ circle three times at a speed of less than 5 mph (8 km/h), and the compass will function normally. Once the calibration is complete, the display will return to a compass reading. Variance is the difference between magnetic north and geographic north. In some areas, the difference between the two can be great enough to cause false compass readings. If this happens, follow these instructions to set the variance for your particular location: 1. Find your location on the zone map earlier in this section. Note your zone number. 2. Press and hold both the MODE and the US/MET buttons in the COMP/TEMP mode. 3. After five seconds, the compass will acknowledge the variation mode by displaying the current zone number. When it does, release both buttons. 4.
