Calibration Adjustment
Compass Calibration
Because the vehicle's sheet metal magnetism tends to change over time, the compass may lose accuracy and need to be calibrated. This condition is
indicated if the True North Adjustment does not correct an inaccurate compass. A compass that is newly installed in a vehicle must also be calibrated.
The compass is calibrated by the following procedure:
1.
Find an open area free from steel structures and high voltage power lines.
2.
Point vehicle toward magnetic north. Use a precise compass outside and away from vehicle to make sure vehicle is (+/- 4 degrees) aligned to
magnetic north.
3.
Make sure vehicle is level and that all doors are closed. Also make sure that maplamps in overhead console are off.
4.
Place a paperclip, toothpick, or similar tool into the compass recessed button "A" (Magnetic Compensation Adjustment) hole and push up gently.
At the same time depress the COMP button with your thumb until display shows "SE tN". Release buttons and wait until display flashes" SE tW".
5.
Point vehicle toward magnetic west. Use a precise compass outside and away from vehicle to make sure vehicle is aligned to magnetic west (+/- 4
degrees).
6.
Push up gently on the compass recessed button "A" (Magnetic Compensation Adjustment) until display stops flashing and shows "SE tW".
Release button.
7.
When the outside temperature is displayed, calibration adjustment is finished. The directional heading should show "W".
8.
Perform Compass True North Adjustment as previously outlined.
