From the service manual for my 97 hopefully it's the same procedure for yours:

STANDARD PROCEDURE - 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

While looking around on Google, I found a couple of references to it. You need to make sure to drive really slow when you do it.
