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 remote keyless entry system.
You can use your key to unlock your door from
the outside.
You can lock or unlock the door from the inside by
sliding the manual lever forward or rearward. When the
door is unlocked, you can see a red area on the lever.
The manual lever on each rear door works only that
door's lock.

Programmable Automatic Door Locks
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 you need to 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.

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
be modified.

lock lever located on the
inside edge of each rear
door. Move the lever

open the rear door when the security lock is on, unlock
the door and open the door from the outside.

when the key is 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
then 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.
Remote 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.
Your remote 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.

2-11
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 is
necessary. See the instructions that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation
(Unlock): When you
press unlock, the driver's
door will unlock
automatically, the parking
lamps may flash and the
interior lights will go on.
You can program different feedback settings through the
Driver Information Center (DIC). For more information
see ªDriver Information Center (DIC)º in the Index.
(Lock): Press lock to lock all the doors. Press lock
again within three seconds and the horn will chirp.
(Panic): 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, or by waiting for 30 seconds, or by starting
the vehicle.

2-12
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.
The Driver Information Center (DIC) will display a
RFA # BATTERY LOW message when the transmitter
battery is low.
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.

2-13
To replace the battery in the remote keyless entry
transmitter do the following:
1. Insert a thin coin in the slot between the covers
of the transmitter housing. Gently pry the
transmitter apart.
2. Remove and replace the battery with a three
-volt
CR2032 or equivalent battery, positive (+)
side down.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.
Liftgate/Liftglass
CAUTION:
It can be dangerous to drive with the liftgate or
liftglass 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 or liftglass
open or if electrical wiring or other cable
connections must pass through the seal between
the body and the liftgate or liftglass:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on panel or bi
-level with recirculation off.
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.
