Heading Mode

Heading Mode:

The heading mode is the normal operating mode of the compass. The mode shows the direction the vehicle is heading. The vehicle heading does not change if the vehicle is not moving. The compass display receives Vehicle Speed Sensor (VSS) information to determine vehicle speed. While in the heading mode the following modes can be selected:
^ variation mode
^ calibration mode

If the actual heading changes dramatically, like during a hard turn, the display may slow down to prevent false heading readings.

The auto-calibration feature works continuously while in the heading mode. This feature keeps the compass calibrated over the life of the vehicle. It adjusts for small changes in the vehicles magnetism that occurs over time. This feature makes repeated manual calibration unnecessary.

While in the heading mode, if a malfunction occurs in the system, the word CALIBRATE is displayed until the ignition switch is turned to OFF or the malfunction is corrected. If CALIBRATE is displayed after the compass has been working properly, a strong disturbance in the signal area may be present.
