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. See DIC Vehicle Customization on page 3-56.
Programmable Locking Feature
Following are the two locking modes that can be
programmed:
Mode 1: All doors lock when the transmission is shifted
out of (P) Park.
Mode 2: All doors lock when the vehicle speed is
greater than 8 mph (13 km/h).
The automatic door locks were pre-programmed at the
factory to lock all the doors when the transmission
is shifted into gear. The following instructions detail how
to program your door locks differently than the factory
setting. Choose one of the two programming options
listed previously 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 ON/RUN and LOCK/OFF twice.
Then, with the key in LOCK/OFF, release the
turn signal/multifunction lever. Once you do this,
you will hear the lock switch lock and unlock,
the horn will chirp twice, and a 30-second program
timer will begin.
