Trunk Lock Release
The trunk lock release
button is located to the left
of the steering wheel on
the instrument panel.
Press the button to open the trunk. To use this feature,
your vehicle must be in PARK (P) or NEUTRAL (N)
and the valet lockout switch must be off.

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.
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 AUTO and temperature between
65ÉF (18ÉC) and 85ÉF (29ÉC). 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.

your vehicle.
Manual Rear Side Door Sunshade
Your vehicle may have manual rear side door
sunshades. To use the sunshades, lower the side
windows and hook the top edge of the retractable
sunshades over the edge of the windows and raise the
windows. To remove the shades, lower the windows
and the hooks will disengage automatically.
Theft-Deterrent Systems
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.
The SECURITY light is
located on the instrument
panel cluster.
If the ignition is off and any door is open, the SECURITY
light will ¯ash, 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 the trunk is opened without a key or a
remote keyless entry transmitter, the horn will sound
and the lamps will ¯ash for about 30 seconds.
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 modi®cations 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 ¯ash.
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
Fuses and Circuit Breakers on
page 5-94. 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.
Valet Lockout Switch

Courtesy Lamps
The courtesy lamps are located on the headliner above
the rear seat. These lamps come on by turning the
instrument panel brightness knob fully clockwise or when
any door is opened and it is dark outside. Puddle

backlighting to the door switches and to the exterior
lamp control when a door is opened or if you press the
remote keyless entry transmitter unlock button. If
activated due to the transmitter, the lighting will remain
active for about 40 seconds. Since the entry lighting
system uses the light sensor, it must be dark outside in
order for the courtesy lamps to turn on. The courtesy
lamps turn off approximately 25 seconds after the
last door is closed. They will dim to off if the ignition key
is placed in ON, or immediately deactivate if the
power locks are activated.

This feature prohibits dimming of the digital displays and
backlighting during daylight hours when the key is in
the ignition and the headlamps are on. This feature
operates with the light sensor for the Twilight
Sentinel
žand is fully automatic. When the light sensor
reads darkness outside and the parking lamps are
active, the digital displays can be adjusted by turning
the instrument panel brightness knob counterclockwise
to dim and clockwise to brighten lighting.
