Door Locks
CAUTION:
Unlocked doors can be dangerous.

Passengers -- especially children -- can easily
open the doors and fall out of a moving
vehicle. When a door is locked, the handle
won't open it. You increase the chance of
being thrown out of the vehicle in a crash
if the doors aren't locked. So, wear safety
belts properly and lock the doors whenever
you drive.

Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.

Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle:

You can use the keyless entry system, if your vehicle
has this feature.

You can use your key to unlock your door from
the outside.

You can use the power lock switch (if equipped) to
lock or unlock the doors.

To manually lock a door from the inside, slide the
manual lever on your door down. To manually
unlock a door from the inside, slide the lever on
the door up. You will see a colored area on the lever
when the door is unlocked.

Power Door Locks (If Equipped)
If your vehicle has power door locks, the switches are
located on the driver's and passenger's front armrests.
Remove the ignition key and press LOCK to lock all the
doors at once. To unlock the doors, press the raised area
to the right of the key symbol.
On four
-door models use the manual door lock/unlock
lever on each rear door to lock or unlock those doors
from the rear seating area.
Programmable Automatic Door Locks
(If Equipped)
If your vehicle has power door locks, it will be equipped
with an auto lock/unlock feature which enables you to
program your vehicle's power door locks.
The following is the list of available programming options:

All doors lock/Driver's door unlocks only: Press
the lock side of the power lock switch on the door
panel once and then the unlock side once. This
option is unavailable on most vehicles not equipped
with keyless entry.

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

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

No doors lock/None of the doors unlock: Press the
lock side of the power lock switch on the door panel
twice. This turns off the automatic lock feature
(this is the factory setting).

Your vehicle left the factory programmed to have no
doors lock and none of the doors unlock. You can set the
automatic lock feature to lock all the doors when the
vehicle speed is greater than 15 mph (24 km/h) for
two seconds, and then unlock all the doors once the key
is removed from the ignition. The following instructions
detail how to program your door locks differently than
the factory setting. Choose one of the four programming
options listed above before entering the program mode.
To enter the program mode you need to do the following:
1. Begin with the ignition in 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 OFF twice. Then, with the
key in OFF, release the turn signal/multifunction
lever. Once you do this, you will hear the lock switch
lock and unlock and a 30 second program timer
will begin.3. You are now ready to program the automatic
door locks. Select one of the four programming
options listed above, and follow the instructions.
You will have 30 seconds to begin programming.
If you exceed the 30 second limit, the locks will
automatically lock and unlock to indicate that 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 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 be modified.
See your dealer for more information.

Rear Door Security Lock (If Equipped)
With this feature, you can
lock the rear doors so they
can't be opened from the
inside by passengers.
To use the security locks:
1. Open one of the rear doors.
2. You will find a security lock lever on the inside edge
of the rear door. Move the lever up to engage the
security lock. Move the lever down to disengage the
security lock.
3. Close the door.
4. Do the same thing to the other rear door.The rear doors of your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open the rear door when the security lock is on, unlock
the door and open the door from the outside.
Lockout Prevention
This feature stops the power door locks from locking
when the keys are in the ignition and a door is open, to
protect you from locking your key in the vehicle.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all the doors will lock and
the driver's door will unlock.
Leaving Your Vehicle
If you are leaving the vehicle, take your key, open your
door and set the locks from inside. Then get out and
close the door.

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 30 feet (9 m)
away using the remote keyless entry transmitter supplied
with your vehicle.
If your vehicle has this feature, you can lock and unlock
your doors and rear endgate from about 3 feet (1 m) up
to 30 feet (9 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

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.

Operation
UNLOCK: When you press UNLOCK, the driver's
door will unlock automatically, the parking lamps will
flash and the interior lamps will go on. If you press
UNLOCK again within three seconds, the remaining
doors will unlock, the parking lamps will flash and the
interior lamps will go on.
LOCK: Press LOCK to lock all the doors. Press LOCK
again within three seconds and the horn will chirp.
REAR: When you press the REAR button twice within
three seconds to release the rear liftgate glass, the
parking lamps will flash and the interior lamps will go
on. If your vehicle has an automatic transmission, the
transmission must be in PARK (P) or NEUTRAL (N).
If your vehicle has a manual transmission, you must
engage the parking brake.
Remote Panic Alarm
When the button with the horn symbol on the key
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 horn 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 only four transmitters
matched to it.
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.

2-13
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 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.
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 it 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.

2-14
Endgate/Liftgate
CAUTION:
It can be dangerous to drive with the rear
window, endgate or liftgate open because carbon
monoxide (CO) gas can come into your vehicle.
You can't see or smell CO. It can cause
unconsciousness and even death.
If you must drive with the rear window, endgate
or liftgate open or if electrical wiring or other
cable connections must pass through the seal
between the body and the rear window, endgate
or liftgate:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on VENT or OUTSIDE AIR. That will force
outside air into your vehicle. See ªComfort
Controlsº in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Endgate Release
To open a manual lock system from the outside,
insert the key into the lock and turn it counterclockwise
to unlock the glass.
To open a power lock system from the outside, insert the
key into the lock button and turn it counterclockwise.
All the doors will then unlock.
If your vehicle is equipped with the keyless entry system,
your vehicle does not have a lock on the endgate. It is
equipped with a pushbutton to release the glass.
You may also use the keyless entry system, or the
power door locks (if equipped).
