Your vehicle may be equipped with the tire pressure
system which monitors the in ation pressure of the tires.
After the system has “learned” the tire pressure with
properly in ated tires, the LOW TIRE PRESSURE
message will be displayed and four warning chimes will
sound if the tire pressure in one tire becomes 12 psi
(83 kPa) lower than the other three tires.
When you have checked the tire pressures, be sure to

Compass Variance
Compass variance is the difference between magnetic
north and geographic north. In some areas of the country,
the difference is great enough to cause the compass to
give false readings. If this occurs, the compass variance
must be set.
Setting the Variance
Turn the ignition on and cycle the DIC to the
Compass/Temperature mode. Press the RESET button
for about ve seconds. The last entered variancezone number and VAR will be displayed. Press the
MODE button until the proper variance zone number on
the map is shown. Press the RESET button to set
the new variance zone and resume normal operation.
All the display segments will be illuminated brie y
to acknowledge the change in zone number. A chime
will sound to con rm that the new zone number
has been set.
Automatic Compass Calibration
The compass is self-calibrating, which eliminates the
need to manually set the compass. When the vehicle is
new, the calibration process may not be complete. In
these cases CAL will be displayed, and all segments of
the compass will be illuminated where the compass
reading is normally displayed.
To calibrate the compass, in an area free from large
metal objects, make one to two 360° turns. The
calibration symbol will turn off and the compass reading
will be displayed.

Manual Compass Calibration
If the compass appears erratic and the calibration
symbol does not appear, you must manually put the
compass into the calibration mode.
Turn the ignition on and cycle the DIC to the
Compass/Temperature mode. Press the RESET button
for at least 10 seconds until the calibration symbol
appears and all segments of the compass display are
illuminated. A chime will sound to con rm that the
calibration mode is active. Release the button and
complete two or three 360° turns in an area free from
large metal objects. The calibration symbol will turn
off and the compass reading will be displayed. A chime
will sound to verify that the calibration is complete.
Error Displays
An error of the speed sensor or fuel sender will
cause -E- to be displayed.
In the absence of vehicle communications,
adash--isdisplayed.
If one of these error messages appear, see your
GM dealer.
Trip Computer
There are ve trip computer displays which may be
stepped through by pushing the MODE button.
The information will appear in the following order:
AVG ECON (Average Fuel Economy):This shows the
average fuel economy since the last reset.
INST ECON (Instantaneous Fuel Economy):This
shows fuel economy for the most recent second
of driving.
RANGE (Trip Range):This shows the estimated
distance that can be traveled with the remaining fuel.
The fuel economy used to calculate range is based
on the last few hours of driving. When in a low
fuel condition, LO is displayed.
FUEL USED (Trip Fuel Used):This shows the
accumulated fuel used since the last reset.
AVG SPEED (Average Speed):This shows the
average speed since the last reset.
Resetting the Trip Computer
Press and hold the RESET button for at least three
seconds. The reset is acknowledged with all segments
of the display lit brie y and a chime. A reset can
