If you live on the line, you can pick the zone area you
are most likely to drive in. In Alaska, use Zone 9 or 10.
In Hawaii, use Zone 7.
Changing Your Zone Number
1. Press MODE to display COMPASS CALIBRATION.
2. Press SELECT to display RESET CHANGES ZONE.
3. Press RESET until your number appears.
4. Press MODE to exit the COMPASS CALIBRATION
MODE and store the new zone number. When the
MODE button is pressed, the DIC will return to
the VEHICLE DATA mode.
Calibrating the Compass
All electronic compasses need to know the magnetic
pro le of your vehicle. This is called calibration and
is done automatically by your compass. However, if you
would like to manually calibrate the compass, the
following instructions will show you how.
Sometimes, strong magnetic elds can affect the
compass. If the compass display does not show a
direction, and CALIBRATE COMPASS is displayed on
the DIC, try calibrating the compass as follows:
1. Drive the vehicle to an open, at area.
2. Press MODE to display COMPASS CALIBRATION.3. Press SELECT to display PRESS RESET TO
RECALIBRATE and then press the RESET
button.
4. The display will change to SLOWLY DRIVE IN
SMALL CIRCLES. Drive the vehicle in small
circles. Do not drive faster than 10 mph (16 km/h).
5. Continue to drive in circles until the CALIBRATION
COMPLETE message is displayed on the DIC and
a direction is shown for the compass.
Your compass should be calibrated. You will know this
when a direction is shown and the CALIBRATE
COMPASS message is no longer displayed.
Compass Accuracy
Your compass may show different headings around
bridges, power lines, large metal objects and steep hills.
This is normal and is true of compasses in general.
If you put large metal objects like golf clubs in the trunk,
they could affect accuracy. If the affect is minimal, the
compass will adapt to these objects over time.
If you use an antenna with a magnetic base, it is best to
mount it away from the center of the trunk near the
rear window.

Care of Your CDs
Handle CDs carefully. Store them in their original cases
or other protective cases and away from direct
sunlight and dust. If the surface of a CD is soiled,
dampen a clean, soft cloth in a mild, neutral detergent
solution and clean it, wiping from the center to the edge.
Be sure never to touch the side without writing when
handling CDs. Pick up CDs by grasping the outer edges
or the edge of the hole and the outer edge.
Care of Your CD Player
The use of CD lens cleaners for CD players is not
advised, due to the risk of contaminating the lens of the
CD optics with lubricants internal to the CD mechanism.
Diversity Antenna System
The AM-FM antennas are located in the windshield and
rear window. Make sure that the inside surfaces of
the windshield and rear window are not scratched and
that the grid lines on the glass are not damaged. If
the inside surfaces are damaged, they could interfere
with radio reception.Notice:Do not apply aftermarket glass tinting with
metallic lm. The metallic lm in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to your
backglass antenna due to metallic tinting materials
will not be covered by your warranty.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window antenna and/or the rear window defogger.
Repairs would not be covered by your warranty. Do
not clear the inside rear window with sharp
objects.
If static is heard on the radio, when the rear window
defogger is turned on, it could mean that a defogger grid
line has been damaged. If this is true, the grid line
must be repaired.
If adding an aftermarket cellular telephone to your
vehicle, and the antenna needs to be attached to the
glass, make sure that the grid lines for the AM-FM
antennas are not damaged. Make sure the cellular
telephone antenna does not touch a grid line.

The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted. Reduce your speed
according to your speedometer, not to your sense
of motion. After driving for any distance at higher
speeds, you may tend to think you are going slower
than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles that
rst part of the journey. Wear comfortable clothing
and shoes you can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course, you
will nd experienced and able service experts in GM
dealerships all across North America. They will be ready
and willing to help if you need it.Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
Lamps:Are they all working? Are the lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all in ated to the
recommended pressure?
Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Maps:Do you have up-to-date maps?
