Door Locks
CAUTION:
Unlocked doors can be dangerous.
Passengers -- especially children -- can easily
open the doors and fall out. When a door is
locked, the inside handle won't open it.
Outsiders can easily enter through an unlocked
door when you slow down or stop your vehicle.
This may not be so obvious: You increase the
chance of being thrown out of the vehicle in a
crash if the doors aren't locked. Wear safety belts
properly, lock your doors, and you will be far
better off whenever you drive your vehicle.
There are several ways to lock and unlock your vehicle.
Your vehicle may be equipped with the Keyless Entry
System. For more information, see ªKeyless Entry
Systemº in the Index.
To unlock your door from the outside, use your key.
To lock the front doors and
sliding side door from the
inside, slide the lock levers
down. To unlock the front
doors and the sliding side
door from the inside, slide
the lock levers up. When the
red mark on the lock lever
is visible, the door is
unlocked.
Power Door Locks (If Equipped)
If your vehicle has power
door locks, press the power
door lock switch 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.
Every vehicle with power door locks has a pulse lock
system. A pulse lock system works like this:
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.
All models have overriding door locks. When a door
is locked, the inside door handle will not work the
latch. This will help stop a door from being
accidentally opened.
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 option, you can lock and unlock
your doors or unlock your rear hatch 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 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 to determine if battery replacement or
transmitter resynchronization is necessary. See the
instructions that follow.

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.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation
When you press UNLOCK, the driver's door will
unlock automatically. If you press UNLOCK again
within five seconds, all doors will unlock. All doors will
lock when LOCK is pressed. The interior lamps will
come on whenever you lock or unlock the doors.
Pressing the REAR 2X button twice within three
seconds will unlock the rear cargo doors.
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 two transmitters
matched to it.

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 will prevent anyone from recording and playing
back the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and simultaneously press and hold the LOCK
and UNLOCK buttons on the transmitter for eight
seconds. The door locks should cycle to confirm
synchronization. If the locks do not cycle, see your
dealer for service.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.

2-11 Sliding Door Security Lock
Your vehicle's sliding side
door is equipped with a
security door lock, located
at 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 at 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. 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.

Hatch
CAUTION:
It can be dangerous to drive with the rear
swing
-out windows, 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 swing-out windows,
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 swing
-out
windows, 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 (Option)
You can use your key to unlock the hatch and all the
other doors from the outside. Insert the key into the
hatch release button and turn it counterclockwise. All
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.
To open the hatch, unlock it, press the button and lift the
handle located in the center of the door.

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
If you park in a lot where someone will be watching
your vehicle, it's 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.
Passlock

Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
enables fuel if the ignition lock cylinder is turned with a
valid key. If a correct key is not used or the ignition lock
cylinder is tampered with, fuel is disabled.
During normal operation, the SECURITY light will go
off approximately five seconds after the key is turned to
the RUN ignition position.
