5-8 Instruments and Controls Compass Calibration The compass can be manually calibrated. Only calibrate the compass in a magnetically clean and safe location, such as an open parking lot, where driving the vehicle in circles is not a danger. Also calibrate the compass, away from tall buildings, utility wires, manhole covers, or other industrial structures, if possible. Compass Calibration Procedure 1. Before calibrating the compass, check that the compass is set to the correct variance zone. See "Compass Variance (Zone) Procedure" earlier in this section. Do not operate any switches such as window, sunroof, climate controls, seats, etc. during the calibration procedure. 2. Press T until PRESS V TO CALIBRATE COMPASS displays. 3. Press V to start the compass calibration. 4. The DIC will display CALIBRATING DRIVE IN CIRCLES. Drive the vehicle in tight circles at less than 8 km/h (5 mph) to complete the calibration. The DIC will display CALIBRATION COMPLETE for a few seconds then returns to the PRESS V TO CALIBRATE COMPASS display. 2. Find the vehicle's current location and variance zone number on the map. Zones 1 through 15 are available. 3. Press V to scroll through and select the appropriate variance zone. 4. Press 3 until the vehicle heading, for example, N for North, is displayed in the DIC. 5. Calibrate the compass. See "Compass Calibration Procedure" following. If the DIC display does not show a heading, for example, N for North, or the heading does not change after making turns, there may be a strong magnetic field interfering with the compass. Interference may be caused by a magnetic antenna mount, magnetic note pad holder, or any other magnetic item. Turn off the vehicle, move the magnetic item, then turn on the vehicle and calibrate the compass.
