2002 GMC YUKON XL Owners Manual

2-57Global positioning capabilities will not be available if
satellite signals are obstructed.
OnStar will not function if the vehicle's battery is
discharged or disconnected. It may also be inoperative if
the vehicle is in an accident and the OnStar or vehicle
electrical system components are damaged.
OnStar is the communication link between you and
existing governmental emergency roadside service
providers. OnStar will receive your call and use
reasonable effort to contact an appropriate provider.
OnStar cannot promise that the providers will respond in
a timely manner or at all. Sunroof (If Equipped)
Your vehicle may be equipped with a power sliding
sunroof. To open or close your sunroof, the ignition
needs to be on or RAP needs to be active. See ªRetained
Accessory Powerº in the Index.
Press and release the rear side of the button located in
the front overhead console to express
- open the glass
panel and sunshade. To close the glass panel, press and
hold the front of the button. The glass will not be fully
seated unless the button is held until the glass stops
moving. With the sunroof closed, press the forward side
of the button to open the sunroof to the vent position.

2-58 The sunroof is also equipped with a sunshade which you
can pull forward to block sun rays.
If a hand, arm, or other object is blocking the sunroof
glass panel as it is closing, the glass panel will stop at
the obstruction. After the obstruction is removed, the
glass panel can be closed or opened.
Use care not to leave the sunroof open for long periods
of time as debris may collect in the tracks.
If the battery has been recharged, disconnected or is not
working, you may need to reprogram the sunroof. To do
this, start the vehicle and press the forward side of the
sunroof switch until the glass panel moves to a fully
closed position. Release, and press again to move to the
vent position which occurs when the sunroof is fully
tilted rearward. This will reset the memory and enable
the sunroof to function properly. HomeLink

2-59Programming the HomeLink Transmitter Do not use the HomeLink Transmitter with any garage
door opener that does not have the stop and reverse
feature. This includes any garage door opener model
manufactured before April 1, 1982.
Be sure that people and objects are clear of the garage
door you are programming.
It is recommended that a new battery be installed in
your hand
- held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Decide which one of the three channels (one of the
HomeLink buttons) you want to program.
2. Press and hold the desired button on HomeLink
through Step 3. 3. When the HomeLink indicator light begins to blink
slowly (this may take up to 30 seconds), hold the
hand
- held transmitter about 1 to 3 inches (3 to 8 cm)
away from HomeLink and then press and hold the
transmit button on the hand
- held transmitter.
Continue to hold both buttons until the indicator
light on HomeLink begins to flash rapidly (this may
take up to 90 seconds).
If you have trouble programming HomeLink, make
sure that you have followed the directions exactly as
described and that the battery in the hand
- held
transmitter is not weak. If you still cannot program it,
move the hand
- held transmitter to the left or right or
forward or backward or flip it upside down. HomeLink
may not work with older garage door openers that do
not meet current Federal Consumer Safety Standards.
If you cannot program the transmitter after repeated
attempts, refer to ªTraining a Garage Door Opener with
Rolling Codesº later in this section or contact the
manufacturer of HomeLink at 1
- 800
- 355
- 3515,
or on the internet at www.homelink.com.
Be sure to keep the original hand
- held transmitter in
case you need to erase and reprogram HomeLink.

2-60Training a Garage Door Opener with a
ªRolling Codeº Feature (If Equipped) If you have not previously programmed the hand
- held
transmitter to HomeLink, see ªProgramming the
HomeLink Transmitterº listed previously. If you have
completed this programming already, you now need to
train the garage door opener motor head unit to
recognize HomeLink.
1. Find the ªLearnº or ªSmartbuttonº on the garage
door opener motor head unit. The exact location and
color will vary by garage door opener brand. If you
have difficulty finding the Learn or Smart button,
refer to your garage door opener owner's manual or
contact the manufacturer of HomeLink at
1
- 800
- 355
- 3515, or on the internet at
www.homelink.com.
Because of the steps involved, it may be helpful
to have another person assist in programming
the transmitter. 2. Press the Learn or Smart button on the garage
door opener motor head unit. An indicator light will
begin to flash when the motor head unit enters the
training mode.
Following this step, you have 30 seconds to
start Step 3.
3. Return to HomeLink in your vehicle and firmly
press and release the programmed HomeLink button
three times.
The rolling
- code garage door opener should now
recognize HomeLink. You may either use HomeLink
or the hand
- held transmitter to open the garage door.
If after following these instructions, you still have
problems training the garage door opener, contact the
manufacturer of HomeLink at 1
- 800
- 355
- 3515,
or on the internet at www.homelink.com.

2-61Canadian Programming Canadian Owners: During programming, the hand
- held
transmitter may automatically stop transmitting after two
seconds. In this case, you should press and hold the
HomeLink button (see Steps 2 and 3 under ªProgramming
the HomeLink Transmitterº) while you press and re
- press
(cycle) your hand
- held transmitter every two seconds until
HomeLink is trained.
Operating the HomeLink Transmitter Press and hold the appropriate button on HomeLink for
at least half of a second. The indicator light will come
on while the signal is being transmitted. Erasing Channels To erase all three programmed channels, hold down the
two outside buttons until the indicator light begins to
flash (approximately 20 seconds). Release both buttons.
Resetting Defaults To reset HomeLink to default settings, hold down the
two outside buttons until the indicator light begins to
flash (approximately 20 seconds). Continue to hold both
buttons until the HomeLink indicator light turns off and
then release both buttons.
