lockout feature off. When the lockout feature is off,
you can open the trunk using either the keyless entry
transmitter or the trunk release button located near
the headlamp switch on the instrument panel.
— (On):Press this side of the button to turn the lockout
feature on. When the lockout feature is turned on,
the trunk cannot be unlocked with the keyless entry
transmitter or the trunk release button located near the
headlamp switch on the instrument panel.
If the valet lockout feature is on it will also disable the
Universal Home Remote transmitter, if equipped.

Content Theft-Deterrent
The security light is
located on the instrument
panel cluster.
To arm the system:
1. Open the door.
2. Lock the door using the power door lock switch with
the door open or the Remote Keyless Entry (RKE)
transmitter. The security light will ash.
3. Close all the doors. The security light will come on
and stay on for approximately 30 seconds.
If a door or the trunk is opened without a key or a
RKE transmitter the horn will sound and the lamps will
ash for about 30 seconds.The theft-deterrent system will not arm if you lock the
doors with a key or use the manual door lock. It arms
only if you use a power door lock with the door open or
the RKE transmitter.
To avoid arming the alarm by accident:
Lock the vehicle with the door key or the manual
door lock.
Always unlock a door with a key or use the RKE
transmitter system. Pressing the unlock button
on the RKE transmitter, or unlocking a door with the
key disarms the content 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 RKE transmitter
system, or by starting the car with a valid key.
Changes or modications made to this system by
other than an authorized service facility could void
authorization to use the theft system.

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 lamps
are located on the bottom of the front and rear door trim.
Professional vehicles have an additional dome lamp
and also opera lamps.
Entry Lighting
This feature turns on the courtesy lamps and the
backlighting for the door switches and the exterior lamp
control when a door is opened or if the remote keyless
entry transmitter unlock button is pressed. If activated
due to the transmitter, the lighting remains 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 turned to
ON/RUN, or immediately deactivate if the power locks
are activated.
Parade Dimming
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 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.
Reading Lamps
The reading lamps are located on the overhead console
on the headliner and in the rear door opening. These
lamps come on automatically when any door is opened
and it is dark outside.
For manual operation, press the button to turn them on.
Press it again to turn them off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
