Delayed Locking
This feature makes it easier to use the power door

your vehicle.
The ®rst time you attempt to lock the doors using the
power lock switch or the remote keyless entry
transmitter, with a door or the liftgate open, three chimes
will signal that delayed locking is being used.
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

delayed locking feature was programmed on, or
enabled. The mode may have been changed since it
left the factory. 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.

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.
Mode 2:All doors lock when the vehicle speed is
greater than 8 mph (13 km/h).
Mode 3:No automatic door locking.
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 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. Turn the key to RUN and LOCK twice. Then, with
the key in LOCK, 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.
3. You are now ready to program the automatic door
locks. Select one of the three programming options
listed above, and press the lock side of the power
door lock switch to cycle through the lock options.
You will have 30 seconds to begin programming.
If you exceed the 30 second limit, 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, 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 locks 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 auto lock/unlock setting will not

HomeLink
žbuttons while keeping the indicator
light in view.
3. Simultaneously press and hold both the desired
button on HomeLink
žand the hand-held transmitter
button. Do not release the buttons until Step 4

žbuttons,
begin with Step 2 under ªProgramming HomeLinkž.º
Do not repeat Step 1 as this will erase all of the
programmed channels.If the indicator light blinks rapidly for two seconds
and then turns to a constant light, continue with
Steps 6 through 8 following to complete the
programming of a rolling-code equipped device
(most commonly, a garage door opener).
6. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the ªLearnº
or ªSmartº button. This can usually be found where
the hanging antenna wire is attached to the
motor-head unit.

programmed HomeLink
žbutton for two seconds,
then release. Repeat the press/hold/release
sequence a second time, and depending on the
brand of the garage door opener (or other rolling
code device), repeat this sequence a third time
to complete the programming.
HomeLink
žshould now activate your rolling-code
equipped device.
To program the remaining two HomeLink
žbuttons,
begin with Step 2 of ªProgramming HomeLinkž.º Do not
repeat Step 1.
