The compass may need to be calibrated in certain cases. If calibration is required, the character C appears in the mirror's display. The earth is divided into 15 magnetic zones. The compass is initially set for the zone to which the vehicle was delivered, and should always be adjusted if the vehicle is driven to a new magnetic zone. A "C" will be displayed if calibration becomes necessary. 73 02 Instruments and controls Mirrors To calibrate the compass: 1. Stop the vehicle in a large, open area, away from traffic. 2.
