Compass Display (If Equipped) The Compass can display direction indicated by N, S, E, W, NE, NW, SE and SW. The sensor for the compass display is located on the back side of the rear view mirror. The Compass can be set to one of 15 geographic zones. To set the ZONE, first locate the compass module on the center rear view mirror post. Press and hold the reset button located on top of the compass module until the display in the message center changes to show the current zone setting (1-15). Release the reset button and press it agian repeatedly until the current zone is displayed (see zone map). After 10 seconds the display will return to normal. Your zone will then be updated. The Compass is continually self-calibrating and should not require calibration, however a manual-calibrating mode can be initiated. NOTE: Compass calibration requires that the vehicle be driven 2-3 mph (3-5 km/h) in at least two 360 degree circles. A safe location free of vehicle and pedestrian traffic will be required. To manually calibrate the compass, locate the reset button on the top side of the compass module. Press and hold the reset button until the Compass display indicates "CIRCLE SLOWLY". Once the button has been released, slowly drive the vehicle in circles until the "CIRCLE SLOWLY" indicator disappears. This may require several complete circles. 19
