Trunk
CAUTION:
It can be dangerous to drive with the trunk lid
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 trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on AUTO or ECON and the temperature
between 65 F (18 C) and 85 F (29 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.
Trunk Lock Release
To use this feature, your
vehicle must be in PARK (P)
or NEUTRAL (N) and the
VALET lockout switch must
be off.
Press the trunk release button, located on the left side of
the instrument panel, to open the trunk.
You can also press the trunk button on the remote
keyless entry transmitter to access the trunk
compartment. To disable the use of this feature, see
ªValet Lockout Switchº in the Index.

2-13
Trunk Lid Tie Down
CAUTION:
Driving with the trunk lid open can allow
dangerous CO (carbon monoxide) gas to come
into your vehicle. You can't see or smell CO.
It can cause unconsciousness and even death.
CAUTION: (Continued)
CAUTION: (Continued)
If you ever need to drive with your trunk lid
open, then:

Make sure all windows, the rear seat
pass
-through and sunroof are closed.

Turn the fan on your heating and cooling
system to its highest speed, with the setting
on VENT. This forces fresh outside air into
your vehicle.

Open all air ducts on the instrument panel.
Don't use the trunk lid tie down if you are towing
a trailer because of the danger of CO.

2-14
This feature is used to secure the trunk lid if it will not
close completely, such as when carrying large packages
in the trunk.
1. Attach the clip end of the tie down to the ªDº ring on
the trunk lid (see view A).
2. Attach the hook end of the tie down to the striker
located at the center of the trunk sill (see view B).
3. Tighten the tie down by pulling the free end of the
cord until secure.
4. To remove the tie down, press the clip end release
and loosen the cord.

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.

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.
