2-45 Cornering Lamps
The cornering lamps come on when the headlamps or
parking lamps are on and you signal a turn. They
provide more light for cornering.
Twilight Sentinel

This control is next to the
headlamp knob. It
automatically switches the
lamps on and off by sensing
how dark it is outside.
To operate the Twilight Sentinel, leave the lamp knob
off and move the TWILIGHT control to any position
but OFF.If you move the control all the way to the right, the
lamps will remain on for approximately three minutes
after the ignition has been turned to OFF or LOCK. If
you move the control so it is just on, the lamps will go
off quickly when you turn the ignition switch out of
RUN. You can adjust the delay time from only a few
seconds to three minutes.
If it's dark enough outside and the Twilight Sentinel
control is off, a HEADLAMPS SUGGESTED message
will display on the Driver Information Center (DIC).
This message informs the driver that turning on the
exterior lamps is recommended (it's become dark
enough outside to require the headlamps and/or other
exterior lamps). Turning on the Twilight Sentinel, the
headlamp switch or the fog lamp switch will remove the
HEADLAMPS SUGGESTED message.

Light Sensor
The light sensor for the DRL and the Twilight Sentinel
is located in the center of the front defogger grille. If
you cover the sensor, it will read ªdarkº and the lamps
will come on.
Exterior Lighting Battery Saver
If the manual parking lamp control has been left on, the
exterior lamps will turn off approximately 10 minutes
after the ignition is turned to LOCK or ACCESSORY.
This protects draining the battery in case you have
accidentally left the headlamps or parking lamps on. If
you need to purposely leave the lamps on for more than
10 minutes with the ignition in LOCK or ACCESSORY,
turn the manual control knob off and then back on. To
delay the lamps from turning off, see ªTwilight
Sentinelº in the Index.
Interior Lamps
Instrument Panel Intensity/Brightness
Control
The digital displays automatically dim when it becomes
dark outside and your lights are on. When it's dark, the
brightness control can be manually adjusted by turning
the lamp control knob counterclockwise to dim and
clockwise to brighten the lighting. The digital displays
automatically brighten when it becomes light outside,
although backlighting will remain active at the selected
brightness as long as the lights are on.

2-47 Courtesy Lamps (DeVille Only)
The courtesy lamps are located in the roof in the rear
seat. These lamps come on with the control lamp knob
or when any door is opened and it is dark outside.
Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the door switches and to
the lamp control knob when a door is opened or if you
press a remote keyless entry transmitter button. Since
the illuminated entry system has a photocell, this means
that it must be dark outside in order for the courtesy
lamps or backlighting to turn on. The courtesy lamps
turn off approximately 20 seconds after the last door is
closed or after the ignition key is placed in the ignition.
Parade Dimming
This feature prohibits dimming of the digital displays
during daylight while the headlamps are on. This feature
operates with the light sensor for the Twilight Sentinel and
is fully automatic. When the light sensor reads darkness
outside, the digital displays can be adjusted by turning the
lamp control knob counterclockwise to dim and clockwise
to brighten lighting. Backlighting to the instrument panel
will turn on regardless of light conditions.
Reading Lamps (DeVille d'Elegance and
DeVille Concours Only)
The reading lamps are located in the roof. 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.

2-48 Map Lamps
These lamps are located in the front overhead panel.
Press the button to turn them on. Press it again to turn
them off.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle's
battery against drainage from the interior lamps,
trunk lamp, glove box lamp, cigarette lighters or the
garage door opener. When the ignition is turned off, the
power to these features will automatically turn off after
10 minutes (three minutes if a new car has 15 miles
(24 km) or less). Power will be restored for an additional
10 minutes if any door is opened, the trunk is opened or
the courtesy lamp switch is turned on.
Storage Mode Personalization
This feature is for long-term use and must be
programmed through the Driver Information Center
(DIC) while the ignition is in RUN. Storage mode
personalization protects the battery by placing your
vehicle in a storage mode so that the radio, amplifiers,
instrument cluster and remote keyless entry will not
drain the battery over a long period of time. For
programming information, see ªMemory and
Personalization Featuresº in the Index.

Mirrors
Electrochromic Day/Night Rearview Mirror
with Compass
Your vehicle has an electrochromic inside rearview
mirror with a compass.
When set in the MIRROR position, this mirror
automatically changes to reduce glare from headlamps
behind you.
The mirror also includes an eight
-point compass
display in the upper right corner of the mirror face.
When on, the compass automatically calibrates as the
vehicle is driven.When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause the
liquid cleaner to enter the mirror housing.
Mirror Operation
The right side of the button, located at the bottom of the
mirror, turns the electrochromic mirror on and off. To
turn on the automatic dimming feature, press MIRROR.
To turn off automatic dimming, press MIRROR again.
The green indicator light will be illuminated when this
feature is active.

which includes an open storage compartment and a dual
cupholder that unfolds for use. To open, lift the front
edge. (This feature is available on vehicles with leather
interiors only.)
Convenience Net
The convenience net is located inside the back wall of
the trunk. Put small loads, like grocery bags, behind the
net. It can help keep them from falling over during sharp
turns or quick starts and stops.
The net is not for larger, heavier loads. Store them in the
trunk as far forward as you can. When not using the net,
hook the net to the tabs securing it to the sill plate.

Cigarette Lighter
The cigarette lighter is located near the ashtray. Press it
all the way in and release. It will pop back by itself
when it's ready to light. You may also have a lighter
located at the rear seat air outlet.
Note: Power to the cigarette lighter will shut off
10 minutes after the ignition is turned off. This helps
to prevent battery drainage. For more information, see
ªInadvertent Battery Saverº in the Index.
NOTICE:
Don't hold a cigarette lighter in with your hand
while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
Sun Visors
Swing down the visor to block out glare. It can also be
detached from the center mount and moved to the side
while the auxiliary sunshade remains to block glare
from the front. Pull the front shade from the headliner
and position it to your preference.
The driver's sunshade is also equipped with a storage
flap that can be used for maps or toll tickets.

Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. If you have previously programmed a transmitter
channel, proceed to Step 2. Otherwise, hold down
the two outside buttons on the Universal Transmitter
until the indicator light begins to flash rapidly (after
20 seconds). Then release the buttons. This
procedure initializes the memory and erases any
previous settings for all three channels.
2. Decide which one of the three channels you want to
program. Hold the end of the hand
-held transmitter
about 2 to 5 inches (5 to 13 cm) away from the
surface of the Universal Transmitter so that you can
still see the indicator light.
3. Using both hands, press the hand
-held transmitter
button and the desired button on the Universal
Transmitter. Continue to press both buttons
through Step 4.
4. Hold down both buttons until you see the indicator
light on the Universal Transmitter flash slowly and
then rapidly. The rapid flashing indicates that the
Universal Transmitter has been programmed.
Release both buttons once the indicator light starts
to flash rapidly.If you have trouble programming the Universal
Transmitter, make sure that you have followed the
directions exactly as described. The Universal
Transmitter may not work with older garage door
openers that do not meet current Federal Consumer
Safety Standards. If you cannot program the transmitter
after repeated attempts, refer to ªRolling Code
Programmingº later in this section or contact the
Universal Transmitter manufacturer at 1
-800-355-3515.
Be sure to keep the original hand
-held transmitter
in case you need to erase and reprogram the
Universal Transmitter.
Note to Canadian Owners: During programming, the
hand
-held transmitter may automatically stop
transmitting after one or two seconds. In this case, you
should press and re
-press the button on the hand-held
transmitter every two seconds without ever releasing the
button on the Universal Transmitter. Release both
buttons when the indicator light on the Universal
Transmitter begins to flash rapidly.
