2004 CADILLAC DEVILLE light

Fog Lamps
If your vehicle has fog lamps, use them for better vision
in foggy or misty conditions.
The fog lamp button is
located to the left of the
steering wheel on the
instrument panel.
When you press the fog lamp button, a fog lamp symbol
in the button and the fog lamp light on the instrument
panel cluster will come on to indicate that the fog lamps
and the parking lamps are on.
Press the button again to turn them off.
If you turn on the high-beam headlamps, the fog lamps
will turn off. They will turn back on again when you
switch to low-beam headlamps.When the Twilight Sentinel
®is on and the fog lamps are
turned on, the fog lamps, headlamps and parking
lamps will remain on.
The ignition must be on for the fog lamps to operate.
Cornering Lamps
The cornering lamps come on when the headlamps or
parking lamps are on and you signal a turn with the
multifunction lever. They provide more light for cornering.
Twilight Sentinel®
This lever is located next
to the exterior lamp
control. It automatically
turns the lamps on and off
by sensing how dark it
is outside.
To operate the Twilight Sentinel
®, leave the exterior
lamp control in the off position and move the TWILIGHT
lever to any position but OFF.
3-20

If you move the lever all the way to the right, the lamps
will remain on for approximately three minutes after
the ignition has been turned to OFF. If you move
the lever so it is barely on, the lamps will go off quickly
when you turn the ignition switch out of OFF. You
can adjust the delay time from only a few seconds to
about three minutes.
If it is dark enough outside and the Twilight
Sentinel
®lever 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 is become
dark enough outside to require the headlamps and/or
other exterior lamps). Turning on the Twilight
Sentinel
®or turning the exterior lamp control to the
headlamp position 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 “dark” and the
exterior lamps or the HEADLAMPS SUGGESTED
message will be displayed whenever the ignition is on.

Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have been
left on, the exterior lamps will turn off approximately
10 minutes after the ignition is turned to OFF. This
protects against draining the battery in case you have
accidentally left the headlamps or parking lamps on. The
battery saver does not work if the headlamps are
turned on after the ignition switch is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn the
lamps back on. To delay the lamps from turning off, see
“Twilight Sentinel
®” listed previously in this section.
Interior Lamps
Instrument Panel Brightness
This feature controls the brightness of the instrument
panel lights.
The knob for this feature is
located to the right of the
Twilight Sentinel
®lever.
Press the knob to release it to the outward position.
Turn the knob clockwise to brighten the lights or
counterclockwise to dim them. Press the knob to return
it to the original storage position.

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.
Entry Lighting
This feature turns on the courtesy lamps and the
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.
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
operates with the light sensor for the Twilight
Sentinel
®and 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.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher revolutions per minute (rpm) setting than
normal to make sure the battery charges. High electrical
loads may occur when several of the following are
on: headlamps, high beams, fog lamps, rear window
defogger, the climate control fan at high speeds, heated
seats and engine cooling fans.
If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer
to clear the glass, the heated seats may not get as warm
as they usually do and the fan may cut back to a
lower speed. For more battery saving information, see
“Battery Saver Active Message” underDIC Warnings
and Messages on page 3-65.

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.
Night Vision System
The optional Night Vision System can help you see better
when you drive at night. The system works by sensing
heat given off by objects in its eld of view. Warmer
objects, such as pedestrians, animals and other moving
vehicles, will appear whiter. Colder objects, such as the
sky, signs and parked vehicles, will appear darker.Use this system as an aid to help you in seeing objects
beyond the headlamps. Do this by occasionally
glancing at the image as you would a rearview mirror.
Do not stare at the image.
3-25

Remember that the Night Vision System can only help
you see objects that are warmer or colder than the
surroundings. It can not sense things like brake lights,
turn signals or emergency ashers, traffic lights or signs.
In dry, clear weather, the system can see pedestrians,
animals and the direction of the road ahead. In light
rain, light snow or light fog the image may not be
as clear and you may not be able to see the direction of
the road ahead. In more severe weather conditions,
the image may be unclear and not usable.
{CAUTION:
Do not use the Night Vision System to replace
your normal view of the road ahead. It can not
tell you how far away things are. It senses only
warmer or colder objects, not all objects.
Driving by staring at the image might cause
you not to see important objects in the road
ahead. If you do not see something in time,
you could have a crash in which you and
others could be injured. Use the Night Vision
System only as a driving aid.It is also important to keep your windshield, the HUD
(Head-Up Display for the Night Vision System) lens and
the camera lens clean. If you do not keep everything
clean, system performance may be affected.
The HUD system is located on the driver’s side of the
instrument panel, next to the windshield and the camera
is located behind the center of the front grille.
Use only household glass cleaner and a soft cloth to
clean the HUD or camera lens. Wipe gently and
dry thoroughly.
Notice:When cleaning, be careful not to scratch
the HUD or camera lenses. Do not spray glass
cleaner directly on the HUD lens because the
cleaner could leak inside the unit and cause
damage.
The camera must also be aligned to work correctly. If
the camera needs adjustment, see your dealer. Do
not attempt to adjust the camera yourself.

The URPA display is
located inside the vehicle,
above the rear window.
It has three color-coded
lights that can be seen
through the rearview mirror
or by turning around.
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R). When the system comes on,
the three lights on the display will briey illuminate to
let you know that the system is working. If your vehicle is
moving in REVERSE (R) at a speed greater than
3 mph (5 km/h), the red light will ash to remind you the
system does not work at this speed.The rst time an object is detected while in
REVERSE (R), a chime will sound and the following
will occur in sequence, depending on the distance from
the object:
At 5 feet (1.5 m) a chime will sound and one amber
light will be lit;
at 40 inches (1.0 m) both amber lights will be lit;
at 20 inches (0.5 m) a continuous chime will sound
and all three lights (amber/amber/red) will be lit; and
at 1 foot (0.3 m) a continuous chime will sound and
all three lights (amber/amber/red) will ash.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the
rear sensors to recognize an object, it must be within
operating range.
If the URPA system is not functioning properly, the
display will ash red, indicating that there is a problem.
The light will also ash red while driving if a trailer is
attached to your vehicle, or a bicycle or object is on the
back of, or hanging out of your trunk. The light will
continue to ash until the trailer or the object is removed
and your vehicle is driven forward at least 15 mph
(25 km/h).
