Compass Calibration
COMPASS CALIBRATION
AUTOMATIC CALIBRATION
The compass is self calibrating which eliminates the need to manually set the compass. When the vehicle is new, the compass may appear erratic and CAL will be displayed. After completing one 360° turn with the vehicle traveling less than 8 km/h (5 mph) in an area free from large metal or metallic objects, CAL will turn off and the compass will function normally.
MANUAL CALIBRATION
If the compass appears erratic and CAL does not appear, you must manually put the compass into the calibration mode. To ensure proper compass calibration, make sure the compass variance is properly set before manually calibrating the compass.
To put the compass into calibration mode: Turn the ignition to the ON position. Press and hold the center button for 6 seconds to change the display between VAR (compass variance) and CAL (compass calibration) modes. To recalibrate the compass, CAL should display for a complete 1 1/2 360° turns in a area free from large metal objects or power lines. When the compass has been calibrated, the CAL symbol will turn off and the compass will function normally.
