2005 CADILLAC DEVILLE Owners Manual

When the Twilight Sentinel®lever is on and it is dark
enough outside, the low-beam headlamps at reduced
intensity will turn off and normal low-beam headlamp
operation will occur.
When the Twilight Sentinel
®lever is on and it is bright
enough outside, the regular lamps will go off, and
the low-beam headlamps at reduced brightness will take
over. If you start your vehicle in a dark garage, the
automatic headlamp system will come on immediately.
Once you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
knob is in the full bright position. SeeInstrument
Panel Brightness on page 3-20.
If it is dark enough outside and the Twilight Sentinel
®
lever is off, a HEADLAMPS SUGGESTED message will
display on the Driver’s Information Center (DIC). This
message informs the driver that turning on the exterior
lamps is recommended even though the DRL are
still illuminated.Turning on the Twilight Sentinel
®or the headlamps will
deactivate the DRL and remove the HEADLAMPS
SUGGESTED message. If the parking lamps or the fog
lamps were turned on instead, the DRL will still
deactivate and the HEADLAMPS SUGGESTED
message will continue to be displayed.
To idle your vehicle with the DRL off at night, turn off the
Twilight Sentinel
®and shift the transaxle into PARK (P).
Placing your vehicle in PARK (P) disables the DRL.
The DRL will stay off until you shift out of PARK (P).
To drive your vehicle with the DRL off, turn off the
Twilight Sentinel
®and manually turn on the parking
lamps or fog lamps (if equipped).
As with any vehicle, you should turn on the regular
headlamp system when you need it.

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.
3-18

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 because it has 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.
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.
3-21

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 3-60.
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, 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
If your vehicle is equipped with the Night Vision System,
it 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.
3-22

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.
The Night Vision System can be operated if:
The instrument panel brightness knob is in any
position except OFF.
It is dark enough outside.
The headlamps or fog lamps (if equipped) are on.
The ignition is turned to ON.
3-23

The controls for this feature are located to the left of
and below the steering wheel. They are used to adjust
the brightness and location of the image. Adjust the
IMAGE control so the image is as low as possible while
remaining visible.
Slide the dimmer control until the image is no brighter
than necessary to clearly and comfortably see the image.When the system comes on, you will see the Night
Vision System symbol in the image. After about
one minute, you should see the view of the road ahead.
If you do not see the image after about two minutes
(on cold days it may take longer for the image to
display), there may be something wrong with the
system. See your dealer for service.
{CAUTION:
If the Night Vision System image is too bright,
or too high in your eld of view, it may take
you more time to see things you need to see
when it is dark outside. Be sure to keep the
image dim and placed low in your eld of view.
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.
