Press the set/reset button to scroll through and select the appropriate variance zone. Navigate to one of the trip/fuel menu screens to view the direction the vehicle is moving.

Compass Calibration The compass can be manually calibrated. Only calibrate the compass in a safe location where driving the vehicle in circles is not a problem. If "CAL" should ever appear in the DIC display, the compass may need calibration. 2. Find the vehicle's current location and variance zone number on the map. Zones 1 through 15 are available. 196
