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 and the temperature between
65F (18C) and 85F (29C). That will
force outside air into your vehicle. See
ªComfort Controlsº in the Index.

If you have air outlets on or under the

Theft-Deterrent System
The SECURITY light is
located on the instrument
panel cluster.

light will flash, reminding you to arm the system.
To arm the system, do the following:
1. Open the door.
2. Lock the door using the power door lock switch with
the door open 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 approximately 30 seconds.
If a door or a trunk is opened without a key or a remote
keyless entry transmitter, the horn will sound and the
lamps will flash for about 30 seconds.

2-19
Remember, the theft-deterrent system won't arm if you
lock the doors with a key or use the manual door lock. It
activates only if you use a power door lock with the
door open or the remote keyless entry transmitter.
To avoid activating the alarm by accident do
the following:

The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don't want to arm the theft
-deterrent system.

Always unlock a door with a key or use the remote
keyless entry transmitter system. Pressing the unlock
button on the remote keyless entry transmitter
disables the theft
-deterrent system. Unlocking a door
any other way will activate the alarm when a door or
the trunk is opened.
If you activate the alarm by accident, unlock the driver's
door with your key. You can also turn off the alarm
by using the unlock button on the remote keyless
entry transmitter system, or by starting the car with a
valid key.
Changes or modifications made to this system by other
than an authorized service facility could void
authorization to use the theft system.
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 system and close the door.
Wait 30 seconds until the SECURITY lamp goes off.
3. Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
hazard lights will flash.
You can turn off the alarm by unlocking the driver's
door with your key, using the unlock button on the
remote keyless entry transmitter or by starting the car
with a valid key.
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 arm the
theft
-deterrent system when leaving your vehicle.
