4. Press the trip/fuel button until the vehicle heading, for
example, N for North, is displayed in the DIC. Or, if
the vehicle does not have DIC buttons, press and
hold the trip odometer reset stem for two seconds to
select the next available variance zone. Repeat this
step until the appropriate variance zone is displayed.
5. If calibration is necessary, calibrate the compass.
See “Compass Calibration Procedure” following.
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 eld 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
V
TO CALIBRATE COMPAS (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.
If your vehicle has the DURAMAX
®Diesel engine, see
the DURAMAX Diesel manual for more information.
CHANGE ENGINE OIL SOON
This message displays when the engine oil needs to be
changed. When you change the engine oil, be sure to

needs to be checked. You can receive more than one tire
pressure message at a time. To read the other messages
that may have been sent at the same time, press the
set/reset button or the trip odometer reset stem. If a tire
pressure message appears on the DIC, stop as soon as
you can. Have the tire pressures checked and set to
those shown on the Tire Loading Information label. See
Tires on page 5-67,Loading the Vehicle on page 4-34,
andInflation - Tire Pressure on page 5-76. The DIC also
shows the tire pressure values. See “DIC Operation and
Displays (With DIC Buttons)” earlier in this section. If the
tire pressure is low, the low tire pressure warning light
comes on. SeeTire Pressure Light on page 3-45.
