Under certain circumstances the compass may have to be calibrated especially if the vehicle is driven over a long distance trip. Reset the zone through the DIC if the compass zone is not set correctly. If the compass heading is blank or the driver information center (DIC) shows CAL or C, the compass must be re-calibrated.
Compass variance is the difference between the earth's magnetic north and the true geographic north. If the compass is not set in the zone where you live, the compass may give false readings. The compass must be set to the variance zone in which the vehicle is travelling.
Press and hold the reset stem in the IPC until the currently set variance zone number (0-30) and direction (E or W) appears in the DIC. Refer to the owners manual for your variance zone map to determine the correct zone.
If the zone does not change while turning the reset stem, try turning it in the opposite direction.
You cannot reset the Compass mode. This mode is retained during ignition OFF.
The compass can be manually calibrated. Only calibrate the compass in a magnetically clean and safe location, such as an open parking lot, where driving the vehicle in circles is not a danger. It is suggested to calibrate away from tall buildings, utility wires, manhole covers, or other industrial structures, if possible.
If C or CAL should ever appear in the DIC display, the compass should be calibrated.
If the DIC display does not show a heading, for example, N for North, or the heading does not change after making turns, there may be a strong magnetic field interfering with the compass. Such interference may be caused by a magnetic CB or cell phone antenna mount, a magnetic emergency light, magnetic note pad holder, or any other magnetic item. Turn off the vehicle, move the magnetic item, then turn on the vehicle and calibrate the compass.
To calibrate the compass, use the following procedure:
Do not operate any switches such as window, sunroof, climate controls, seats, etc. during the calibration procedure.
When the calibration is complete, the vehicle heading, for example, N for North, displays instead of the C or CAL.
Compass variance is the difference between the earth's magnetic north and true geographic north. If not adjusted to account for compass variance, the compass in the vehicle could give false readings. Under certain circumstances, such as during a long distance cross-country trip, it will be necessary to compensate for compass variance and reset the zone through the DIC.
The compass direction will show CAL or C if it needs to be calibrated. Before calibrating the compass, drive the vehicle to an area that is magnetically clean (free of large metallic objects).
