Programmable Automatic Door Locks - GMC Yukon Denali 2003 Owner's Manual

Programmable Automatic Door
Locks
Your vehicle is equipped with an automatic lock/unlock
feature which enables you to program your vehicle's
power door locks. You can program this feature through
the Driver Information Center (DIC), or by the following
method.
Programmable Locking Feature
The following is the list of available programming
options:
Mode 1: All doors lock when the transmission is shifted
into gear. This is the mode that is pre-programmed in
the factory for your vehicle.
Mode 2: All doors lock when the vehicle speed is
greater than 8 mph (13 km/h).
Mode 3: No automatic door locking.
The following instructions tell you how to change the
automatic door lock mode. Choose one of the three
programming options listed above before entering the
program mode. To enter the program mode, do the
following:
1. Begin with the ignition off. Then pull the turn
signal/multifunction lever toward you and hold
it there while you perform the next step.
2-10
2. Turn the key to RUN then back to LOCK twice.
Then, with the key in LOCK, release the turn
signal/multifunction lever. Once you do this, the
doors will lock and unlock, the horn will chirp twice,
and a 30-second timer will begin. You are now
ready to program the automatic door lock feature.
3. Press the door lock switch once. You will hear one,
two, or three chimes. The number of chimes tells
you which lock mode is currently selected. Continue
to press the door lock switch until the number of
chimes that you hear matches the number of
the mode that you want. If you take longer than
30 seconds, the locks will automatically lock
and unlock and the horn will chirp twice to indicate
that you have left the program mode. If this
occurs, you can repeat the procedure beginning
with Step 1 to re-enter the programming mode.
You can exit the program mode any time by turning the
ignition to RUN (the doors will automatically lock and
unlock and the horn will chirp twice to indicate that you
are leaving the program mode). If the lock/unlock
switches are not pressed while in the programming
mode, the current automatic settings will not be
modified.
