Wiper
-Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
approximately 20 seconds.
In order to operate the wiper
-activated headlamps, the
Twilight Sentinel
must be turned on. This feature lights
the way in poor weather and it also makes your vehicle
more visible to other drivers. If the wiper
-activated
headlamps are on and the ignition switch is turned off, the
wiper
- activated headlamps will immediately turn off.The wiper
-activated headlamps will deactivate if you
turn off the Twilight Sentinel or if the windshield wipers
have been turned off for a period of one or two seconds.
Lamps on Reminder
You will hear a warning chime if you open any door
while leaving the lamps on, if the manual headlamp
control is activated. An exception to this is when you're
using Twilight Sentinel.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
The DRL system will make the low
-beam headlamps
come on at reduced brightness when:

the ignition is on,

the headlamp switch is off and

the transaxle is not in PARK (P).
When DRL are on, only your low
-beam headlamps (at
reduced brightness) will be on. No other exterior lamps
such as the parking lamps, taillamps, etc. will be on
when the DRL are being used. Your instrument panel
won't be lit up either.

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.

Compass Operation
Press COMPASS once to turn the compass on or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for
approximately two seconds. After two seconds, the
mirror will display the compass heading.
If, after two seconds, the display does not show a
compass heading (ªNº for North, for example), there
may be a strong magnetic field interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, magnetic note pad holder or a
similar magnetic item.
Compass Calibration
If the letter ªCº appears in the compass display, the
mirror may need calibration.
The mirror can be calibrated in one of two ways:

Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display reads a direction, or

Drive the vehicle on your everyday routine.Compass Variance
The mirror is set in zone eight upon leaving the factory.
It will be necessary to adjust the compass to compensate
for compass variance if you live outside zone eight.
Under certain circumstances, as during a long distance
cross
-country trip, it will be necessary to adjust for
compass variance. Compass variance is the difference
between earth's magnetic north and true geographic
north. If not adjusted to account for compass variance,
your compass could give false readings.
To adjust for compass variance:
1. Use the COMPASS button located at the bottom of
the mirror.
2. Press and hold the COMPASS button until a zone
number appears in the display.
3. Find your current location and variance zone number
on the following zone map.

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.
