Compass Variance (Zone) Procedure

1. Do not set the compass zone when the vehicle is moving. Only set when the vehicle is in PARK (P).

   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.

2. Locate your geographic location. Refer to the variation zone map.
3. Find the vehicle's current location and variance zone number/direction on the map.
4. To select the appropriate variance zone, turn the reset stem clockwise or counterclockwise and then release to advance to the next available zone. Repeat as needed.

   If the zone does not change while turning the reset stem, try turning it in the opposite direction.

5. Once the appropriate variance zone is selected, press the reset stem. A flashing C will display.
6. Calibrate the compass. See "Compass Calibration Procedure" following.

You cannot reset the Compass mode. This mode is retained during ignition OFF.
