2-6Last Door Closed Locking
The Last Door Closed Locking feature makes it easier to
use your power door locks to lock all the doors and the
liftgate when leaving your vehicle.
When any door or the liftgate is open, the first time you
attempt to lock the doors using the power lock switch or
the remote keyless entry transmitter (if equipped), this
will result in three chimes to signal that Last Door
Closed Locking is being used. All doors and the liftgate
can be opened for five 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 the remote keyless entry
transmitter a second time.
If the ignition is in RUN or ACCESSORY, this feature
will not lock the doors.
To turn the Last Door Closed Locking feature off or on,
see ªMultifunction Alarm Locks and Lighting Choicesº
in the Index.
Automatic Door Locks
All of the doors will lock automatically when you move
your shift lever out of PARK (P). All doors will unlock
automatically when the ignition is turned off while the
shift lever is in PARK (P).
You can program the Automatic Door Locks to operate
with the remote keyless entry system and to lock and
unlock automatically to suit your needs. See
ªMultifunction Alarm Locks and Lighting Choicesº in
the Index.
With the Automatic Door Locks feature, you can still
lock or unlock the doors at any time, either manually or
with the power door lock switches.
Sliding Door Delayed Locking
If the sliding door is open when you use your power door
locks to lock the vehicle, the sliding door is not locked.
Normally the Last Door Closed Locking feature will be
used to lock the sliding door after it has been closed.
When the ignition is on or if the Last Door Closed
Locking feature has been overridden or programmed to
be off, the Sliding Door Delayed Locking feature will
lock your sliding door for you. Three seconds after the
sliding door is closed, all the doors will lock. If you
have the dual sliding doors, all doors will lock
three seconds after both sliding doors are closed.

Lockout Deterrent
The Lockout Deterrent feature makes it difficult for you
to lock your keys in your vehicle. If the driver's door is
open while the keys are in the ignition, a chime will
sound and you will not be able to use your power door
lock switch to lock the vehicle.
If you don't leave the keys in the ignition or if you use
the manual door lock, you could still lock your keys in
your vehicle. Always remember to take your keys
with you.
To turn this feature off or on, see ªMultifunction Alarm
Locks and Lighting Choicesº in the Index.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from the inside. Then get out and
close the door.

unlock your doors or unlock your liftgate from about
3 feet (1 m) up to 30 feet (9 m) away using the remote
keyless entry transmitter supplied with your vehicle.

Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
This system has a range of about 3 feet (1 m) up to
30 feet (9 m). At times you may notice a decrease in
range. This is normal for any remote keyless entry
system. If the transmitter does not work or if you have
to stand closer to your vehicle for the transmitter to
work, try this:

Check to determine if battery replacement or
resynchronization is necessary. See the instructions
that follow.

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation

Remote Lock Confirmation (If Equipped)
If your vehicle is equipped with the Content
Theft
-Deterrent system, your remote keyless entry
transmitter will have this feature.
When you use the remote keyless entry transmitter to
lock your vehicle, your parking lamps will flash briefly
to let you know the command has been received. If you

ªMultifunction Alarm Locks and Lighting Choicesº in
the Index.
Remote Unlock Confirmation (If Equipped)
If your vehicle is equipped with the Content
Theft
-Deterrent system, your remote keyless entry
transmitter will have this feature.
When you use your remote keyless entry transmitter to
unlock your vehicle or to operate the power sliding door
(if equipped), your parking lamps will flash briefly to let
you know the command was received.
If you would like to change the way the parking lamps
operate with Remote Unlock Confirmation, see
ªMultifunction Alarm Locks and Lighting Choicesº
in the Index.Remote Alarm (If Equipped)
When you press the horn button on the remote keyless
entry transmitter, the parking lamps will flash and the
horn will sound. This will allow you to attract attention,
if needed.
Remote Power Sliding Door Operation (If Equipped)
If your vehicle is equipped
with a power sliding door
(see ªPower Sliding Doorº
later in this section), your
remote transmitter will have
a button that has a van
symbol on it. Press it to
open or close the
sliding door.

2-10
You can operate the power sliding door with the remote
transmitter only when the power sliding door override
switch on the overhead console is disabled.
Matching Transmitter(s) To Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have only four transmitters
matched to it.
See your dealer to match transmitters to another vehicle.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.Replacing the Battery in the Remote Transmitter
1. Insert a flat object like a dime into the slot on the
side of the transmitter and twist to separate
the halves.

yellowblue
2-11
2. Gently pry the battery out of the transmitter. Do not
use the metal flanges to ªpop outº the battery.
3. Replace the battery.
4. Reassemble the transmitter. Make sure the halves are
snapped together tightly so water will not get in.
5. Check the transmitter operation. If needed, follow
the instructions on resynchronizing your
remote transmitter.
NOTICE:
When replacing the battery, use care not to touch any
of the circuitry. Static from your body transferred to
these surfaces may damage the transmitter.
Resynchronization
Your remote keyless entry system uses a continually
changing code for increased security. Normally, the
receiver in your vehicle will keep track of this
changing code.

Loss of synchronization will occur if the transmitter
is activated more than 256 times while out of range
of the vehicle.

Loss of synchronization will occur after the battery
replacement if the transmitter is immediately
activated more than 16 times while out of range of
the vehicle.
If your remote keyless entry transmitter has stopped
working, you may need to resynchronize the transmitter
to the vehicle receiver. To do this, press the LOCK and
UNLOCK buttons together and hold for at least seven
seconds or until the horn sounds if equipped with
Content the Theft
-Deterrent system. Check the
transmitter operation.
