Vehicle Magnetic Compensation

ON-VEHICLE SERVICE

PROCEDURES FOR CALIBRATING THE COMPASS






1. Press the "COMP" button. The visual display is now in compass mode and the vehicle's directional heading (N, NE, E, SE, S, SW, W and NW) will be displayed.

Pressing the "COMP" button a second time will turn off the visual display.






2. If the display reads "C," there may be a strong magnetic field interfering with the compass. In this case, the compass may need calibration.






3. Drive the vehicle in a circle at about 5 mph (8 km/h) or less until the display reads a direction.
