Compass Calibration
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 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:Compass Calibration Procedure
1. Before calibrating the compass, make sure the
compass zone is set to the variance zone in which
the vehicle is located. See “Compass Variance
(Zone) Procedure” earlier in this section.
Do not operate any switches such as window,
sunroof, climate controls, seats, etc. during the
calibration procedure.
2. Press the vehicle information button until PRESS
VTO CALIBRATE COMPASS displays. Or, if the
vehicle does not have DIC buttons, press the trip
odometer reset stem until CALIBRATE COMPASS
displays.
3. Press the set/reset button to start the compass calibration. Or, if the vehicle does not have DIC
buttons, press and hold the trip odometer reset
stem for two seconds to start the compass
calibration.
4. The DIC will display CALIBRATING: DRIVE IN CIRCLES. Drive the vehicle in tight circles at less
than 5 mph (8 km/h) to complete the calibration.
The DIC will display CALIBRATION COMPLETE
for a few seconds when the calibration is complete.
The DIC display will then return to the
previous menu.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that
some action may be needed by the driver to correct the
condition. Multiple messages may appear one after
another.
Some messages may not require immediate action, but
you can press any of the DIC buttons on the instrument
panel or the trip odometer reset stem on the instrument
panel cluster to acknowledge that you received the
messages and to clear them from the display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These
messages require action before they can be cleared.
You should take any messages that appear on the
display seriously and remember that clearing the
messages will only make the messages disappear, not
correct the problem.
The following are the possible messages that can be
displayed and some information about them.
