2-3 Power Windows (If Equipped)
If you have power windows, the controls are located on
each of the side doors.
The driver's door has a switch for the passenger's
windows as well. Your power windows will work when
the ignition has been turned to ACCESSORY or RUN
or when Retained Accessory Power (RAP) is present.
See ªRetained Accessory Powerº in the Index.Press the rear of the switch with the power window
symbol on it to lower the window or the front of the
switch to raise it.
The driver's window also has an express down feature
that allows the window to be lowered without holding
the switch. Press and hold the rear of the window switch
for one second to activate the express down mode.
The express down mode can be canceled at any time by
pressing the opposite side of the switch. To open the
window partway, lightly tap the switch until the window
is at the desired position.
If you have power windows, the driver's door power
window switch has a lockout feature. This feature
prevents the rear windows from operating except from
the driver's position when the front driver's door button
labeled WINDOW LOCK is engaged. When the button
is not engaged, the rear power windows will operate.

Your vehicle has one
double
-sided key for the
ignition and all door locks
as well as the spare tire
hoist lock.
Your vehicle may also have
a key that locks and unlocks
the center floor console
only (if equipped).
If you ever lose your keys, your dealer will be able to
assist you with obtaining replacements.
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.

2-6
There are several ways to lock and unlock your vehicle.
Use the keyless entry system (if equipped) or use the
door key.

switch, marked ªLº on
either front door to lock
all the doors at once.
Press the recessed side of the switch marked ªUº to
unlock all the doors at once.

theft
-deterrent system (if equipped). See ªContent
Theft
-Deterrentº in the Index.
Programmable Automatic Door Locks
Your vehicle is equipped with an auto lock/unlock feature
which enables you to program your power door locks.
Your vehicle left the factory programmed to have the
automatic lock feature 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.
To enter the program mode you need to:
1. Beginning with the ignition in OFF, pull back on
the turn signal/multifunction lever all the way toward
you and hold it while you perform the next step.
2. Turn your key to ON 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.

2-8
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 ten
seconds to begin programming. If you exceed the
ten 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 ON (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 auto
lock/unlock setting will not be modified.
The following is a list of the available programming options:

For more information, see your dealer.
Lockout Prevention
This feature protects you from locking your key in the
vehicle 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.
Child Security Locks (If Equipped)

they cannot be opened from the inside by passengers.
This feature is located on the inside of the rear doors.
Move the button forward to engage the security feature.
Move the button rearward to return the door locks to
normal operation.

2-9
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 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 is
necessary. See the instructions that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.
Operation
UNLOCK: Pressing this button once will unlock the
driver's door. The parking lamps will flash and the interior
lights will come on. The ground illumination lamps 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.

2-10
LOCK: Pressing this button once will lock all of the
doors. Wait one second, then press LOCK again 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 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 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.
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.

2-11
To replace the battery in the keyless entry transmitter:
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 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.

2-12
Liftgate Caution
CAUTION:
It can be dangerous to drive with the liftgate
glass, liftgate or rear doors 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 liftgate glass, liftgate
or rear doors open or if electrical wiring or
other cable connections must pass through the
seal between the body and the liftgate glass,
liftgate or rear doors:

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.
Liftgate Glass and Liftgate
To open a mechanical lock system from the outside,
insert the key into the lock and turn it counterclockwise
to unlock the glass and liftgate.
The liftgate glass can be opened using the pushbutton on
the liftgate after the doors have been unlocked. This can
be done by using either the power door locks or the
remote keyless entry system.
To open the entire liftgate, lift the handle located in the
center of the door.
To lock a power lock system from the outside, insert the
key into the lock button and turn clockwise. All doors will
lock. You may also use the keyless entry system or the
power door locks to lock the liftgate and liftgate glass.
Panel Doors

door locks, you can lock the side doors as well as the rear
doors from inside the vehicle. For more information, see
ªPower Door Locksº earlier in this section.
Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft
-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.Your ignition and transmission will be locked.
Also remember to lock the doors.
If the key is in the ignition, with any door open, and you
try to lock your doors with the power door locks, the
driver's door will not stay locked. This will help to keep
you from locking your keys in the vehicle.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
Even if you park in a lot where someone will be
watching your vehicle, it's still best to lock it up and
take your keys. But what if you have to leave your
ignition key? What if you have to leave something
valuable in your vehicle?

Put your valuables in a storage area, like your
glove box.

Valuables can be locked in the center floor console.

If your vehicle has a remote keyless entry system,
take the transmitter with you.

Lock all the doors except the driver's.
