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.
Use your key to unlock your vehicle from the outside.
You can also use the optional remote keyless entry
system to unlock your vehicle. See ªRemote Keyless
Entry Systemº in the Index.
To lock the door from
the inside, push the
locking lever forward.
To unlock the door, pull the locking lever backward.

2-5 Power Door Locks (If Equipped)
You can lock or unlock
all doors of your vehicle
from the driver's or
front passenger's
door lock switch.
Push the lower portion of the switch to lock the doors.
Push the upper portion of the switch to unlock the doors.
The lever on each rear door works only that door's lock.
It won't lock (or unlock) all of the doors
-- that's a
safety feature.
Rear Door Security Lock (4-Door Models)
Your vehicle is equipped
with rear door security
locks that help prevent
passengers from opening
the rear doors of your
vehicle from the inside.
To Use One of These Locks
1. Use a key to move the lock all the way up.
2. Close the door.
3. Do the same thing to the other rear door lock.
The rear doors of your vehicle cannot be opened from
the inside when this feature is in use.

2-6
To Open a Rear Door With the Security Lock
1. Unlock the door from the inside.
2. Then open the door 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 rear door from the inside. You should let adults and
older children know how to cancel the locks.
To Cancel the Rear Door Lock
1. Unlock the door from the inside and open the door
from the outside.
2. Use a key to move the lock all the way down.
3. Do the same for the other rear door.
The rear door lock will now work normally.Lockout Prevention (If Equipped)
If your vehicle is equipped with remote keyless entry,
you have lockout protection. This feature stops the
power door locks from locking when the keys are in
the ignition and the door is open.
If the power door lock switch is pressed when a door
is open and the key is in the ignition, all the doors will
lock and the driver's door will unlock.
Leaving Your Vehicle
If you are leaving the vehicle, open your door and
set the locks from the inside. Then get out and close
the door.

2-7
Remote Keyless Entry (If Equipped)
If your vehicle has this feature, you can lock and unlock
your doors or unlock your trunk from about 3 feet (1 m)
up to 30 feet (9 m) away using the remote keyless entry
transmitter supplied with your vehicle.
In addition, the system illuminates the interior lamps for
a set period of time.
The remote keyless entry
system consists of a
receiver, which is located
in the vehicle, and two

2-8
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
resynchronization is necessary. See the instructions
that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation
The following functions are available with the remote
keyless entry system:
LOCK: All doors will automatically lock when the
LOCK button is pressed. In addition, if all doors and
the trunk are closed, the headlamps will flash once, the
interior lamps will turn off, and the vehicle anti
-theft
system will arm. If you press the LOCK button again
within five seconds, the horn will chirp to let you know
that the system is armed. The THEFT SYSTEM light
will flash on the instrument panel to let you know the
system is armed. If a door or the trunk is open when
you press the LOCK button, the doors will lock, but the
security system will not arm until all the doors and the
trunk are closed.
Your dealer can change the settings to disable the
headlamp flash feature and horn chirp. Your dealer can
also change the settings to allow the horn to chirp twice
on the first press of the UNLOCK button. See your
dealer for more information.

2-9
UNLOCK: The driver's door will unlock when the
UNLOCK button on the transmitter is pressed. In
addition, the headlamps will flash twice, the dome lamp
will turn on for about 20 seconds or until the ignition
is turned on, and the security system will disarm. The
THEFT SYSTEM light will stop flashing. If you press
UNLOCK again within five seconds, all remaining
doors will unlock.
Your dealer can change the settings to disable the
headlamp flash feature and horn chirp. Your dealer can
also change the settings to allow the horn to chirp twice
on the first press of the UNLOCK button. See your
dealer for more information.
If you use the key to lock or unlock your door or trunk
while the system is armed, you will hear a pre
-alarm
chirp. This will last for 10 seconds, then the full alarm
will sound. This can be avoided by pressing any key fob
button or turning the ignition to START.
If you hear three chirps when you press the UNLOCK
or LOCK button on your transmitter, that means
your security system alarm was triggered while you
were away.Trunk Release: The trunk will unlock anytime when
the vehicle symbol on the transmitter is pressed and the
vehicle speed is less that 2 mph (3 km/h). The headlamps
will flash twice. When the trunk is unlocked using the
transmitter, the security system will be temporarily
disarmed until the trunk is opened and closed again or a
period of one minute elapses at which time the system
will re
-arm.
Your dealer can change the settings to disable the headlamp
flash feature. See your dealer for more information.
Horn Symbol: The horn will sound and the headlamps
and dome lamp will flash alternately when this button is
pressed. This can be turned off by pressing the horn
symbol button again or by turning the ignition to ON.
The alarm will sound for two minutes unless cancelled
by the driver.

2-10
Radio Personalization Feature
Your vehicle can store different radio preset stations
and other settings depending on which keyless entry
transmitter you use to unlock the doors with. The radio
will recall all the stored settings associated with that
transmitter. Any radio setting changes will be assigned
to the transmitter last used to unlock the doors.
This feature can be disabled by your dealer if you desire.
Contact your dealer for further information.
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 Replacing the Battery in the Remote
Keyless Entry System Transmitter
To replace the battery in the transmitter:
1. Use a small coin or flat
-tip screwdriver to separate
the bottom half from the top half of the transmitter.
2. Remove the battery and replace it with the new one.
Make sure the positive (+) side of the battery faces
down. For battery replacement, use a three
-volt
battery, type CR2032, or equivalent.
3. Read the instructions inside the case.4. Put the two halves back together. Make sure the
cover is on tightly, so water won't get in.
5. Check the operation of the transmitter with your
vehicle. If the transmitter does not work, try
resynchronizing the transmitter with the receiver.
Resynchronization
Your remote keyless entry system is equipped with a
security system that prevents anyone from recording and
playing back your signal. The transmitter does not send
the same signal twice to the receiver. The receiver will not
respond to a signal that has been sent to it more than once.
Normally, the transmitter and receiver resynchronize
automatically. However, under certain circumstances,
manual resynchronization may be required.
To resynchronize your transmitter and receiver, follow
these directions:
1. Stand close to your vehicle.
2. Press and hold the LOCK and UNLOCK buttons
on the transmitter at the same time.
3. Hold the buttons for at least 10 seconds. During
this time, the doors should lock and unlock once.
This confirms the resynchronization. If the doors
do not lock and unlock, see your dealer for service.
