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.
To unlock your door from the outside, use your key or
remote keyless entry transmitter, if equipped. For more
information, see ªKeyless Entry Systemº in the Index.
To lock the front doors and
sliding side door from the
inside, slide the manual lock
levers down. To unlock the
front doors and the sliding
side door from the inside,
slide the manual lock levers
up. When the red mark on
the lock lever is visible,
the door is unlocked.

2-9 Power Door Locks (If Equipped)
If your vehicle has power
door locks, press the power
door lock switch located on
the door panel to lock or
unlock all the doors at once.
The power door lock switch will lock or unlock the rear hatch
and Dutch doors. See ªHatch Releaseº in the Index.
When a door is locked, the inside door handle will not
open the door. This will help stop a door from being
accidentally opened.
If the sliding door is open and you press the power door
lock switch, the sliding door will not lock immediately.
After you close the door, the system comes on and locks
the sliding door in about five seconds.
When the key is in the ignition and the power door lock
switch is pressed with a door open, all doors are locked
while the driver's side door remains unlocked.
Programmable Automatic Door Locks
(If Equipped)
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 all the
doors lock automatically when the shift lever is moved
out of PARK (P). All of the doors will unlock when the
shift lever is moved back into PARK (P). The following
instructions detail how to program your door locks.
To enter the program mode you need to do
the following:
1. Begin with the ignition in OFF. Then, 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.

2-10
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 begin programming. If you exceed
the thirty 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 ON (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 auto 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 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 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 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 lock switch on the door panel
twice. This turns off the automatic lock feature.
For more information, see your dealer.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from inside. Then get out and
close the door.
Keyless Entry System (Option)
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 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 will
flash and the interior lights
will go on.
If you press UNLOCK again within three seconds, all
doors will unlock, the parking lamps will flash and the
interior lights will go on.
LOCK: Press LOCK to lock all the doors. Press LOCK
again within three seconds and the horn will chirp.
REAR 2X: When you press the REAR button twice
within three seconds to unlock the rear hatch or cargo
doors, the parking lamps will flash and the interior lights
will go on. If the engine is running, the automatic
transmission must be in PARK (P) or NEUTRAL (N)
for the REAR 2X button to operate.

2-12
Panic Alarm Button
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.
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.

2-13
To replace the battery, do the following:
1. Insert a thin object like a dime to separate the bottom
of the transmitter from the top.
2. Remove the battery and replace it with a new one,
making sure the positive (+) side of the battery is
facing down. Use one Panasonic

three-volt,
type CR2032, or equivalent battery.
3. Snap the top and bottom together.
Sliding Door
To open the sliding side door, pull the handle toward the
back and slide the door to the rear until it rests in the
open position.
To close the sliding side door, pull the handle toward the
front and slide the door forward.

2-14 Sliding Door Security Lock
Your vehicle is equipped
with a sliding door security
lock that helps to prevent
young children or other
passengers from opening
the sliding door using the
inside door handle.
The security door lock is located near the front of the
sliding door.There are two labels on your vehicle to remind you that
you have this feature. One can be seen from the outside
on your sliding door. It is located near the bottom of the
door glass, toward the front of the door. The other label
is located on the front of the sliding door, near the
security door lock.
This feature prevents passengers from opening the
sliding side door from the inside.
To use this feature, do the following:
1. Move the lever all the way up.
2. Close the door.
To open the sliding side door while the security lock is
engaged, unlock the door and open it from the outside.
If you don't cancel the security lock feature, adults or
older children who ride in the rear won't be able to open
the sliding door from the inside. You should let adults
and older children know how the security door lock
works, and how to cancel the lock.

2-15 Canceling the Sliding Door Security Lock
To cancel the security lock, do the following:
1. Unlock the door and open it from the outside.
2. Move the lever all the way down.CAUTION:
If your vehicle is facing downward on a steep
grade (15 percent or more), the door may not
stay open and could slam shut, possibly injuring
someone. To make sure the door does not slam
shut, be sure to hold it open until everyone is
clear of the door, and only then allow it to
slowly close.

2-16
Rear Hatch/Rear Doors
CAUTION:
It can be dangerous to drive with the rear hatch
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 rear hatch or rear
doors open or if electrical wiring or other cable
connections must pass through the seal between
the body and the rear hatch 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 anything but MAX A/C. 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.
Hatch Release
You can use your key to unlock the hatch and all of the
other doors from the outside. Insert the key into the
hatch release button and turn it counterclockwise.
All of the doors will unlock.
You may also use the keyless entry system
described earlier.
The hatch can be opened or closed without a key if the
door lock system is unlocked.

2-17
To open the hatch, unlock it, then press the button and
lift the handle located in the center of the door.
To lock the power lock system from the outside, insert
the key in the hatch release button and turn it clockwise.
All doors will lock.
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 tone reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transmission. Also remember to lock
the doors.
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 key?
Do not leave valuables in your vehicle, since there is no
locking area in which to secure them. Lock all doors
except the driver's.
