Central Door Unlocking System
Your vehicle has a central door unlocking mode and a
theft
-deterrent system. When unlocking the driver's
door, you can unlock the other doors by holding the key
in the turned position for a few seconds or by quickly
turning the door key twice in the lock cylinder.
Power Door Locks
Press the power door lock
button to lock or unlock all
the doors at once. The
power door lock buttons
located on the rear doors
can lock all the doors at
once, but cannot unlock
the doors.
Automatic Door Locks
Your vehicle is equipped with a default mode, so that
every time your doors are closed, the ignition is on and
you move the shift lever out of PARK (P), all the doors
will lock. The doors will unlock every time you stop the
vehicle and move the shift lever back into PARK (P).
If someone needs to get out while your vehicle is not in
PARK (P), have that person use the manual or power
lock. When the door is closed again, it will not lock
automatically. Use the manual or power lock to lock the
door again. If you need to lock the doors before shifting
out of PARK (P), use the manual or power lock button
to lock the doors.
Programmable Automatic Door Locks
With the ignition in ON, the door locks can be
programmed through prompts displayed by the Driver
Information Center (DIC). These prompts allow the
driver to choose various lock settings. For programming
information, see ªMemory and Personalization
Featuresº in the Index.

Rear Door Security Locks
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 this lock:
1. Turn the knob on the passenger's side rear
door clockwise all the way down to the
ENGAGED position.
2. Close the door.
3. Turn the knob on the driver's side rear door
counterclockwise all the way down to the
engaged position.
The rear doors of your vehicle cannot be opened from
the inside when this feature is in use.When you want to open a rear door when the security
lock is on:
1. Unlock the door from the inside.
2. Then open the door from the outside.
To cancel the rear door lock:
1. Unlock the door and open it from the outside.
2. Turn the passenger's side rear door knob
counterclockwise all the way back to the
original position.
3. Turn the driver's side rear door knob clockwise all
the way back to the original position.
The rear door locks will now work normally.
Anti-Lockout Feature
Leaving your key in any ignition position with any door
open will disable the use of the power door lock buttons
as well as the lock button on the remote keyless entry
transmitter. If you close the doors, you can lock them
using the remote keyless entry transmitter. It is always
recommended that you remove the ignition key when
locking your vehicle.
Also, the anti
-lockout feature can be overridden by
holding the driver's power door lock button for three
seconds or longer.

2-9
When you press this symbol to lock the doors, the
parking lamps will flash once and the horn will sound.
The park lamps will not flash, however, if the manual
park lamps are left on. (You can also program your
vehicle so the parking lamps will not flash and the horn
will not sound. For more information, see ªLock/Unlock
Confirmationº in the Index.) This also arms the
theft
-deterrent system.
Press this symbol to open the trunk. (The VALET
lockout switch must be off for this feature to work.)
Your transmitter also comes equipped with an instant
panic alarm. To use the alarm, press this symbol. The
horn will sound and the exterior lights will flash for up
to 30 seconds. To stop the instant panic alarm, press the
symbol again or turn the ignition to ON.
The remote keyless entry transmitter can also be used to
recall the memory settings for up to two drivers. For
more information, see ªMemory Seat and Mirrorsº in
the Index.
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. 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.
Since all vehicles come with only two transmitters. You
must check with your dealer for information on how to
obtain additional transmitters.

2-15
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 chime 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 transaxle. And 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 ignition key?

If possible, park in a busy, well lit area.

Put your valuables in a storage area, like your
trunk or glove box. Be sure to close and lock the
storage area.

Close all windows.

Move the trunk release lockout switch to ON.

Lock the glove box.

Lock all the doors except the driver's.

Then take the door key and remote keyless entry
transmitter with you.

Leave only the valet key.

Take all other keys and the Remote Keyless Entry
transmitter with you.

2-16
Theft-Deterrent System
If the ignition is off and
any door is open, the
SECURITY light will flash,
reminding you to activate
the system.
The light will also flash if the battery has been
disconnected and reconnected. To arm the system, do
the following:
1. Open the door.
2. Lock the door using the power door lock or the
remote keyless entry transmitter. The SECURITY
light should come on and stay on.
3. Close all the doors. The SECURITY light should go
off within about 30 seconds.
The horn will sound and the lamps will flash for about
30 seconds when the door or trunk is opened without the
key or the remote keyless entry transmitter. The horn
also sounds if the locks are damaged.Remember, the theft
-deterrent system won't activate if
you lock the doors with a key or use the manual door
lock. It activates only if you use a power door lock
button or the remote keyless entry transmitter.
To avoid activating the alarm by accident:

Always unlock a door with a known key or use the
remote keyless entry transmitter. (Using a known
key or pressing the unlock button on the remote
keyless entry transmitter disables the theft
-deterrent
system.) Unlocking a door any other way, such
as using an unknown key, will activate the
alarm system.

The vehicle should be locked with the door key after
the doors are closed if you don't want to activate the
theft
-deterrent system.
If you activate the alarm by accident, unlock any door
with your key. You can also turn off the alarm by using
the unlock button on the remote keyless entry
transmitter or by using a known key. The alarm won't
stop if you try to unlock a door any other way

2-18
PASS-Key
III
Your vehicle is equipped with the PASS-Key III
(Personalized Automotive Security System)
theft
-deterrent system. PASS-Key III is a passive
theft
-deterrent system. This means you don't have to do
anything different to arm or disarm the system. It works
when you insert or remove the key from the ignition.
Your PASS
-Key III 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.
PASS
-Key III uses a radio frequency transponder in the
key that matches a decoder in your vehicle.
When the PASS
-Key III system senses that someone is
using the wrong key, it shuts down the vehicle's starter
and fuel systems. The starter will not work and fuel will
stop being delivered to the engine. Anyone using a
trial
-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
When trying to start the vehicle if the engine does not
start and the SECURITY light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.
If the engine does not start, and the key appears to be
undamaged, try another ignition key. At this time, you
may also want to check the fuse (see ªFuses and Circuit
Breakersº in the Index). If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the first key may be faulty. See your
dealer or a locksmith who can service the PASS
-Key III
to have a new key made.

2-19
It is possible for the PASS-Key III decoder to learn the
transponder value of a new or replacement key. Up to
ten additional keys may be programmed for the vehicle.
This procedure is for learning additional keys only. If all
the currently programmed keys are lost or do not
operate, you must see your dealer or a locksmith who
can service PASS
-Key III to have keys made and
programmed to the system.
See your dealer or a locksmith who can service
PASS
-Key III to get a new blank key that is cut exactly
as a current black
-colored driver's key that operates the
system. Do not use a gray
-colored valet key for
this procedure.
To program the new key:

Insert the current driver's key (black in color) in the
ignition and start the engine. If the engine will not
start see your dealer for service.

After the engine has started, turn the key to OFF, and
remove the key.
Insert the key to be programmed and turn it to ON
within ten seconds of removing the previous key.

The SECURITY light will turn off once the key has
been programmed. It may not be apparent that the
SECURITY light went on due to how quickly the
key is programmed.

Repeat the Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the SECURITY light comes
on and stays on, you will be able to start your engine if
you turn it off. Your PASS-Key III system, however, is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by the PASS
-Key
III system at this time.
If you lose or damage a PASS
-Key III key, see your
dealer or a locksmith who can service PASS
-Key III to
have a new key made.

New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º But it will perform better in the long
run if you follow these guidelines:

Don't drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking
-in guideline every
time you get new brake linings.

Don't tow a trailer during break
-in.
See ªTowing a Trailerº in the Index for
more information.
Ignition Positions
If you cannot start your vehicle and you are unable to
remove your key from the ignition, see ªShift Lock
Releaseº in the Index.
CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. A child or
others could be injured or even killed. They could
operate power windows or other controls or even
make the vehicle move. Don't leave the keys in
the vehicle with children.
