2004 GMC ENVOY XL turn signal

Delayed Locking
This feature delays the locking of the doors and the
liftgate when using the power lock or the remote keyless
entry system.
The rst time you attempt to lock the doors with the
driver’s door open, three chimes will signal that delayed
locking is being used. This can be performed by
using either power lock switch or the remote keyless
entry transmitter. All doors and the liftgate can be
reopened for up to ve seconds from the time the last
door is closed.
Five seconds after the last door is closed, all the doors
will lock. You can lock the doors immediately by
using the power door lock switch or by pressing the lock
button on the optional remote keyless entry transmitter
a second time.
If the key is inserted in the ignition, this feature will not
lock the doors. The lockout prevention feature will
operate instead.
You can enable or disable the delayed locking feature.
If the feature is disabled, the doors will lock immediately
when a power door lock switch or remote keyless
entry transmitter lock button is pressed.
Programming Delayed Locking
To turn the delayed locking feature on or off, do the
following:
1. Press and hold the power door lock switch on the
driver’s door in the lock position.
2. Press the remote keyless entry transmitter unlock
button twice.
If the delayed locking feature was on, it will now be off.
If the feature was off, it will now be on.

Programming 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. If you have a newer
garage door opener with rolling codes, please be
sure to follow steps 6 through 8 to complete the
programming of your HomeLink
®Transmitter.
Read the instructions completely before attempting to
program the HomeLink
®Transmitter. Because of
the steps involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink
®programming. It is also
recommended that upon the sale of the vehicle, the
programmed HomeLink
®buttons should be erased for
security purposes. Refer to “Erasing HomeLink®Buttons”
or, for assistance, contact HomeLink®on the internet at:
www.homelink.com or by calling 1-800-355-3515.
Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.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. Press and hold down the two outside buttons,
releasing only when the indicator light begins to
ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
transmitter to the remaining two HomeLink
®buttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
®
buttons while keeping the indicator light in view.
3. Simultaneously press and hold both the desired
button on HomeLink
®and the hand-held transmitter
button. Do not release the buttons until Step 4
has been completed.
Some entry gates and garage door openers may
require you to substitute Step 3 with the procedure
noted in “Gate Operator and Canadian
Programming” later in this section.
4. The indicator light will ash slowly at rst and then
rapidly after HomeLink
®successfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
