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 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.

2-7 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.
When the key is in the ignition and the power door lock
button is pressed with a door open, all doors are locked
while the driver's side door is unlocked.
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.

your doors from about 3 feet (1 m) up to 30 feet (9 m)
away using the remote keyless entry transmitter supplied

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.

2-9
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
transmitter resynchronization 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 five 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 five seconds and the horn will chirp.REAR 2X: When you press the REAR button twice
within five 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.
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 second, 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 two transmitters
matched to it.

2-10 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.
Use one Panasonic
three-volt, type CR2032, or
equivalent battery.
Your transmitter housing snaps apart for ease in
battery replacement.To replace the battery:
1. Insert a small coin or flathead screwdriver 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.
3. Snap the top and bottom together.
4. Test the operation of the transmitter with your
vehicle. If the transmitter does not work, try
resynchronizing the transmitter with the receiver.

2-11
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.

2-12 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.
Canceling the Sliding Door Security Lock
To cancel the security lock:
1. Unlock the door and open it from the outside.
2. Move the lever all the way down.

2-13
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.
