Compass Calibration
Important: Before calibrating the compass, drive the vehicle to a area that is
 magnetically clean, and free of large metallic objects.
- Turn ON the ignition.
 
- Press the MODE button in order to advance to the COMP/TEMP mode.
 
- Simultaneously depress and hold the US/MET and MODE buttons until
 a C is displayed, in approximately 10 seconds.
 
- Release both buttons.
 
- Drive the vehicle in circles at a speed of less than  8 km/h
 (5 mph) until the C is replaced by a proper vehicle heading. The 
calibration  procedure is now complete.
 
Compass Magnetic Variation Adjustment
Important: Magnetic variation adjustments are required when the compass displays
 a constant error in heading. Variation is the difference     between magnetic
   north and true north due to geographical location.
- Locate your geographic location. Refer to the variation zone map.
 
- Turn ON the ignition, with the engine OFF.
 
- Press the MODE button in order to advance to the COMP/TEMP mode.
 
- With the DIC in the COMP/TEMP mode, simultaneously depress and
 hold the MODE and US/MET buttons until VAR CAL is displayed, in approximately
      5 seconds.
 
- Release both buttons.
 
- Press the US/MET button in order to advance to the proper zone
 number.
 
- Press the MODE button in order to enter and set the zone number.
