See "How to Reset the Change Engine Oil Message" in the Index. Compass Variance Compass variance is the difference between magnetic north and geographic north. In some areas of the country, the difference is great enough to cause the compass to give false readings. If this occurs, the compass must be set. 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 degree turns. The calibration symbol will turn off and the compass reading will be displayed. t USE SET TO SELECT ENGLISH METRIC: You can use this display to select English or metric. Press the SET button to toggle between English or metric. The odometer, the trip odometer and if your vehicle is equipped the head-up display will also change.
