Programmable Automatic Door Locks
(If Equipped)
If your vehicle has power door locks, it is equipped with
a feature that enables you to program the door locks.
Your vehicle left the factory programmed to automatically
lock all doors when the vehicle is out of PARK (P), and
all doors unlock when the vehicle is in PARK (P). You can
set the automatic door lock feature to unlock the doors
you select once the vehicle is in PARK (P).
If your vehicle has a manual transmission it left the
factory programmed to lock all doors when the vehicle
speed is greater than 15 mph (24km/h) for two seconds,
and unlock all doors once the key is removed from the
ignition. You can set the automatic door lock feature to
unlock the doors you select once the key is removed
from the ignition.
The following instructions detail how to program your
door locks.To enter the program mode you need to do
the following:
1. Beginning with the ignition in OFF. Pull back on the
turn signal/multifunction lever all the way toward
you until flash
-to-pass is activated, and hold it while
you perform the next step.
2. Turn your key to RUN and OFF twice. Then, with
the key in OFF, release the turn signal/multifunction
lever. Once you do this, you will hear the lock
mechanism lock and unlock.
3. You are now ready to program the automatic door
locks. Select one of the following four programming
options and follow the instructions. You will have
thirty seconds to complete programming. If you
exceed the thirty
-second limit, the locks will
automatically lock and unlock to indicate you have
left the program mode. If this occurs, repeat the
procedure beginning with Step 1. You can exit the
program mode any time by turning the ignition to
RUN (the locks will automatically lock and unlock
to indicate you are leaving the program mode.)
If the lock/unlock switches are not pressed while in
the programming mode, the automatic lock/unlock
setting will not be modified.

The following is a list of the available
programming options:

All doors lock/Only the driver's door unlocks:
Press the lock side of the power door lock switch on
the door panel once and then the unlock side once.

All doors lock/All doors unlock: Press the lock side
of the power door lock switch on the door panel
once, and then the unlock side twice.

All doors lock/None of the doors unlock: Press the
lock side of the power door lock switch on the door
panel once, and then the unlock side three times.

No doors lock/None of the doors unlock: Press the
lock side of the power door lock switch on the door
panel twice. This turns off the automatic lock feature.
For more information, see your dealer.Lockout Prevention
To protect you from locking your key in the vehicle, this
feature stops the power door locks from locking when
the key is in the ignition and a door is open.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all of the doors will lock
and then the driver's door will unlock.

2-11
Child Security Locks (Crew Cabs)
(If Equipped)
With this feature, you can lock the rear side
doors so that they cannot be opened from the
inside by passengers.
Your vehicle may have one of the two child security
lock labels shown. This feature is located on the inside
edge of the rear doors.
Move the lever forward to engage the security feature.
Move the lever rearward to return the door locks to
normal operation.

2-12
Keyless Entry System (If Equipped)
If your vehicle has this feature, you can lock and unlock
your doors from about 3 feet (1 m) up to 100 feet (30 m)
away using the remote keyless entry transmitter supplied
with your vehicle.
Your keyless entry system operates on a radio frequency
subject to Federal Communications Commission (FCC)
Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
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 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.

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

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

2-13
Operation
UNLOCK: Pressing this button once will unlock the
driver's door. The parking lamps will flash and the
interior lights will come on. Pressing UNLOCK again
within three seconds will cause the remaining doors to
unlock. The parking lamps will flash and the interior
lights will come on.
LOCK: Pressing this button once will lock all of the
doors. Press LOCK again within three seconds and the
horn will chirp.
Operating the keyless entry transmitter may interact
with the theft
-deterrent system. See ªContent-Theft
Deterrentº in the Index.Remote Panic Alarm
When the panic button with the horn symbol on the
keyless entry transmitter is pressed, the horn will sound
and the headlamps and taillamps will flash for up to
30 seconds. This can be turned off by pressing the
panic button again, waiting for 30 seconds, or starting
the vehicle.
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 a maximum of four
transmitters matched to it.

2-14
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.
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.
To replace the battery in the keyless entry transmitter, do
the following:
1. Insert a dime, or similar object, in the slot between
the covers of the transmitter housing near the key
ring hole. Remove the bottom by twisting the dime.
2. Remove and replace the battery with a three
-volt
CR2032 or equivalent battery, positive (+) side up.
3. Align the covers and snap them together.
4. Resynchronize the transmitter.
5. Check the operation of the transmitter.

2-15
Resynchronization
Resynchronization may be necessary due to the security
method used by this system. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal that has been sent
previously. This prevents anyone from recording and
playing back the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the LOCK and UNLOCK
buttons on the transmitter at the same time for seven
seconds. The door locks should cycle to confirm
synchronization. If the locks do not cycle, see your
dealer for service.
Rear Doors
Your vehicle may be equipped with a rear access
door(s) that allows easier access to the rear area of the
extended cab.
To open a rear access door
from the outside, first open
the front door. Then, use the
handle located on the front
edge of the rear access door
to open it.
You must fully close a rear access door before you can
close the front door.

2-16
To open a rear access door
from the inside, the front
door must be opened first.
Then, use the handle located
on the inside of the rear
access door to open it.
If your vehicle is a Crew Cab, you can open your doors
from the inside or outside. Your vehicle may also have a
feature which prevents children from opening the rear
doors. See ªChild Security Locksº in the Index for
more information.Tailgate
You can open the tailgate by lifting up on its handle
while pulling the tailgate toward you.
To shut the tailgate, firmly push it upward until
it latches.
After you put the tailgate back up, pull it back towards
you to be sure it latches securely.
