The safety belt locks if there's a sudden stop or a crash,
or if you pull the belt very quickly out of the retractor.
The rear outboard seating positions may have a shoulder
belt tightness adjustment feature. You can tell if your
vehicle has this feature by following the steps below. If
you can add a small amount of slack, your vehicle has
this feature.
If the shoulder belt seems too tight:
1. Sit well back in the seat.
2. Pull the shoulder belt all the way out of the retractor.
3. Let belt go back all the way.
4. Now you can add a small amount of slack. Lean
forward slightly, then sit back. If you've added more
than 1 inch (25 mm) of slack, pull the shoulder belt
out as you did before and start again.
If you move around in the vehicle enough or if you pull
out the shoulder belt, the belt will become tight again. If
this happens, you can reset it.

Safety Belt Extender
If the vehicle's safety belt will fasten around you, you
should use it.
But if a safety belt isn't long enough to fasten, your
dealer will order you an extender. It's free. When you go
in to order it, take the heaviest coat you will wear, so the
extender will be long enough for you. The extender will
be just for you, and just for the seat in your vehicle that
you choose. Don't let someone else use it, and use it
only for the seat it is made to fit. To wear it, just attach it
to the regular safety belt.
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors and
anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from
doing its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt is
torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Replacing Restraint System Parts
After a Crash
If you've had a crash, do you need new belts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if worn
during a more severe crash, then you need new belts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have safety belt
or seat parts repaired or replaced. New parts and repairs
may be necessary even if the belt wasn't being used at
the time of the collision.
If an air bag inflates, you'll need to replace air bag
system parts. See the part on the air bag system earlier in
this section.
If the frontal air bags inflate, you'll also need to replace
the driver's and right front passenger's safety belt
buckle assembly. Be sure to do so. Then the new buckle
assembly will be there to help protect you in a collision.

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

2-17
Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open, lock
the vehicle using the power door lock or the remote
keyless entry transmitter and close the door.
Wait 30 seconds until the SECURITY light goes off.
3. Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
headlamps will flash.
If the alarm does not sound when it should, check to see
if the horn works. The horn fuse may be blown. To
replace the fuse, see ªFuses and Circuit Breakersº in the
Index. If the fuse does not need to be replaced, you may
need to have your vehicle serviced.
To reduce the possibility of theft, always activate the
theft
-deterrent system when leaving your vehicle.
Valet Lockout Switch
The valet lockout switch is
located inside the glovebox.
Pushing the VALET lockout switch to ON will disable
the use of the power trunk, fuel door and garage door
openers. Pushing the switch to OFF again will make
these features reusable. Locking the glove box with the
key will also help to secure your vehicle.
The remote keyless entry transmitter cannot be used to
open the trunk or fuel door if the valet lockout switch is
in the ON position. Also, the valet key will not unlock
the glovebox or trunk.

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.
