Programmable Automatic Door Locks - Chevrolet Silverado Classic 2007 Owner's Manual

Programmable Automatic Door
Locks
Your vehicle may have 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. See DIC Vehicle
Customization on page 281.
Programmable Locking Feature
Following are the two 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 for
automatic transmission vehicles.
Mode 2: All doors lock when the vehicle speed is
greater than 8 mph (13 km/h). This is the mode
that is pre-programmed in the factory for manual
transmission vehicles.
The following instructions tell you how to change
the automatic door lock mode (automatic
transmission only).
Choose one of the two 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. 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
either one or two 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.
