Compass display (if equipped)
The compass reading may be affected when you drive near large
buildings, bridges, power lines and powerful broadcast antennas.
Magnetic or metallic objects placed in, on or near the vehicle may also
affect compass accuracy.
Usually, when something affects the compass readings, the compass will
correct itself after a few days of operating your vehicle in normal
conditions. If the compass still appears to be inaccurate, a manual
calibration may be necessary. Refer to Compass zone/calibration
adjustment.
Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is four
degrees between adjacent zones and will become noticeable as the
vehicle crosses multiple zones. A correct zone setting will eliminate this
error. Refer to Compass zone/calibration adjustment.
Compass zone/calibration adjustment
Perform this adjustment in an open area free from steel structures and
high voltage lines.
For optimum calibration, turn off all electrical accessories (heater/air
conditioning, wipers, etc.) and make sure all vehicle doors are shut.
