112 UNDERSTANDING THE FEATURES OF YOUR VEHICLE turns in an area free from large metal or metallic objects, the "CAL" symbol will turn off and the compass will function normally. Manual Compass Calibration If the compass appears erratic and the "CAL" symbol does not appear, you must put the compass into the Calibration Mode manually. To put into a Calibration Mode: Turn on the ignition switch and set the display to Comp/Temp. Press the RESET button on vehicles equipped with a Compass/ Mini Trip Computer for at least 10 seconds until the "CAL" symbol appears. On vehicles equipped with Compass/Temp press and hold the C/T and US/M buttons for 10 seconds. Release the RESET button and complete three 360° turns in an area free from large metal objects. The "CAL" symbol will turn off and the compass will function normally. CAUTION! Do not place any external magnets, such as magnetic roof mount antennas, in the vicinity of the compass. Do not use magnetic tools when servicing the overhead console. Compass Variance Compass Variance is the difference between magnetic North and Geographic North. In some areas of the country, the difference between magnetic and geographic North is great enough to cause the compass to give false readings. If this occurs, the compass variance must be set. NOTE: Magnetic materials should be kept away from the overhead console.
