6. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the “Learn”
or “Smart” button. This can usually be found where
the hanging antenna wire is attached to the
motor-head unit.
7. Firmly press and release the “Learn” or “Smart”
button. The name and color of the button may
vary by manufacturer.
You will have 30 seconds to start Step 8.
8. Return to the vehicle. Firmly press and hold the
programmed HomeLink
®button for two seconds,
then release. Repeat the press/hold/release
sequence a second time, and depending on the
brand of the garage door opener (or other rolling
code device), repeat this sequence a third time
to complete the programming.
HomeLink
®should now activate your rolling-code
equipped device.
To program the remaining two HomeLink
®buttons,
begin with Step 2 of “Programming HomeLink®.” Do not
repeat Step 1.
Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to “time out” or quit after several seconds of
transmission. This may not be long enough for
HomeLink
®to pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured to
“time out” in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the
“Programming HomeLink
®” procedures (regardless of
where you live), replace Step 3 under “Programming
HomeLink
®” with the following:
Continue to press and hold the HomeLink
®button while
you press and release every two seconds (cycle) your
hand-held transmitter until the frequency signal has been
successfully accepted by HomeLink
®. The indicator light
will ash slowly at rst and then rapidly. Proceed with
Step 4 under “Programming HomeLink
®” to complete.
Using HomeLink®
Press and hold the appropriate HomeLink®button for at
least half of a second. The indicator light will come
on while the signal is being transmitted.

Care of Your CDs and DVDs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc 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 discs. Pick up discs by grasping the outer
edges or the edge of the hole and the outer edge.
Care of Your CD and DVD Player
The use of CD lens cleaners for CDs is not advised, due
to the risk of contaminating the lens of the CD optics
with lubricants internal to the CD mechanism.
Cleaning the Video Screen
Pour some isopropyl or rubbing alcohol on a clean cloth
and gently wipe the video screen. Do not spray
directly onto the screen and do not press too hard or
too long on the video screen.
Fixed Mast Antenna
The xed mast antenna can withstand most car washes
without being damaged. If the mast should ever
become slightly bent, you can straighten it out by hand.
If the mast is badly bent, you should replace it.
Check occasionally to be sure the mast is still tightened.
Chime Level Adjustment
The volume level of the vehicle’s chimes can be
controlled by the radio. To change the volume level,
press and hold pushbutton 6 with the ignition on and the
radio power off. The chime volume level will change
from the normal level to loud, and LOUD will appear on
the display. To change back to the default or normal
setting, press and hold pushbutton 6 again. The chime
level will change from the loud level to normal, and
NORMAL will appear on the display.

Cleaning the Top of the Instrument
Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones
or waxes may cause annoying reections in the
windshield and even make it difficult to see through the
windshield under certain conditions.
Cleaning Interior Plastic Components
Use on a mild soap and water solution on a soft cloth or
sponge. Commercial cleaners may affect the surface
nish.
Cleaning Wood Panels
Use a clean cloth moistened in warm, soapy water (use
mild dish washing soap). Dry the wood immediately
with a clean cloth.
Cleaning the Speaker Covers
Vacuum around a speaker cover gently, so that the
speaker won’t be damaged. Clean spots with just water
and mild soap.
Cleaning Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner or a
liquid household glass cleaner will remove normal
tobacco smoke and dust lms on interior glass. See
Vehicle Care/Appearance Materials on page 5-100.
Notice:If you use abrasive cleaners when cleaning
glass surfaces on your vehicle, you could scratch
the glass and/or cause damage to the rear window
defogger and the integrated radio antenna. When
cleaning the glass on your vehicle, use only a soft
cloth and glass cleaner.
