Compass Calibration
Before calibrating the compass, drive the vehicle to an area that is   magnetically clean or free of large metallic objects. Verify there are no  magnetized objects on the inside or outside of the vehicle close to the mirror.
- Start the engine.
 
- Press and hold the switch for the compass, which may be depicted  as COMP, COMPASS, or On/Off (w/UE1) depending on the type of mirror on the  vehicle, until the letter "C" or "CAL" is displayed.
 
- Drive the vehicle in circles at a speed of less than 8 km/h  (5 mph) until the "C" or "CAL" is replaced  by a proper vehicle heading. The calibration procedure is now complete.
 
Compass Magnetic Variation Adjustment
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.
 World Magnetic Variation Map
- Locate your current geographic location on the World Magnetic Variation  Map.
 
- Turn ON the ignition, with the engine OFF.
 
- Press and hold the switch for the compass, which may be depicted  as COMP, COMPASS, or On/Off (w/UE1) depending on the type of mirror on the  vehicle, until a zone number appears  on the compass display.
 
- Depress the switch for the compass to select the desired zone  number.
 
- Wait 5 seconds, the display will return to a compass heading.  The variance procedure is now complete.
