Automatic Compass Calibration The compass is self-calibrating, which eliminates the need to manually set the compass. When the vehicle is new, the calibration process may not be complete. In these cases the calibration symbol C will be displayed where the compass reading is normally displayed. To calibrate the compass, in an area free from large metal objects, make three 360° turns. The calibration symbol will turn off and the compass reading will be displayed. Error Displays • An error of the vehicle's speed sensor or fuel sender will cause -E- to be displayed. • In the absence of vehicle communications, a dash "- -" is displayed. If one of these error messages appear, see your dealer. Trip Computer There are five trip computer displays available by pushing the MODE button. The information will appear in the following order: AVG ECON (Average Fuel Economy): This shows the average fuel economy since the last reset. INST ECON (Instant Fuel Economy): This shows fuel economy for the most recent second of driving. RANGE (Trip Range): This shows the estimated distance that can be traveled with the remaining fuel. The fuel economy used to calculate range is based on the last few hours of driving. Manual Compass Calibration If the compass appears erratic and the calibration symbol does not appear, you must manually put the compass into the calibration mode. Turn the ignition on and cycle the DIC to the compass/temperature mode. Press both the E/M and MODE buttons simultaneously for at least 10 seconds until the calibration symbol appears. Release both buttons and complete three 360° turns in an area free from large metal objects. The calibration symbol will turn off and the compass reading will be displayed. 3-59
