2002 CADILLAC ELDORADO ignition

2-44
When the Twilight Sentinel lever is on and it's dark
enough outside, the high
-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's bright enough outside, the regular lamps
will go off, and the high
-beam headlamps at reduced
brightness will take over for the DRL.
If it's 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 even though the DRL
are still illuminated (it's become dark enough outside
to require the headlamps and/or other exterior lamps).
Turning on the Twilight Sentinel, the exterior lamp knob
or the fog lamp button will remove the HEADLAMPS
SUGGESTED message.
To idle your vehicle with the DRL off, turn off the
Twilight Sentinel lever 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).
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps
Use the fog lamps 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 button with the fog lamp symbol,
a small indicator light will tell you that the fog lamps
and the parking lamps are in use. Press the button again
to turn them off. Your ignition must be in RUN for the
fog lamps to illuminate.
If you turn on the high
-beam headlamps, the fog lamps
will turn off. They'll turn back on again when you
switch to low
-beam headlamps.
When the Twilight Sentinel is on and the fog lamp
button is pressed, the fog lamps will remain on as well
as the headlamps and parking lamps.

2-45 Cornering Lamps
The cornering lamps come on when you signal a turn.
They provide more light for cornering.
Twilight Sentinel

This feature automatically turns the exterior lamps on
and off by sensing how dark it is outside.
This lever is located
next to the exterior lamp
control knob.To operate the Twilight Sentinel, leave the exterior lamp
knob off and slide the TWILIGHT lever to any position
except OFF.
If you slide 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 or LOCK. If you slide
the lever so it is just on, the lamps will go off quickly
when you move the ignition out of RUN. You can adjust
the delay time from only a few seconds to three minutes.
If it's dark enough outside and Twilight Sentinel 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 or the headlamps will
remove the HEADLAMPS SUGGESTED message.

Light Sensor
The light sensor for the Daytime Running Lamps (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 parking lamps have been left on, the exterior lamps
will turn off approximately 10 minutes after the ignition
is turned to LOCK or ACCESSORY. This protects
against 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
exterior lamps off and then back on. To delay the lamps
from turning off, see ªTwilight Sentinelº in the Index.
Interior Lamps
Instrument Panel Brightness Control
This feature controls the brightness of the instrument
panel lights.
The knob for this feature is located to the left of the
steering wheel on the instrument panel. This knob is also
used to control the exterior lamps. See ªExterior Lampsº
listed previously in this section for more information.
Turn the knob clockwise to brighten the lights or
counterclockwise to dim them.
Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the door controls and
to the exterior lamp 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 is turned to RUN.

2-47 Parade Dimming
This feature prohibits the dimming of the instrument
panel lights 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 instrument
panel lights can be adjusted by turning the exterior
lamp knob counterclockwise to dim and clockwise to
brighten lighting. Backlighting to the instrument panel
will turn on, regardless of light conditions.
Reading Lights
The front reading lights are located either in the
headliner or above the windows if you have a sunroof.
The two rear lights above the rear side windows.
To turn them on, turn the exterior lamp knob all the way
clockwise. These lights and the interior courtesy lights
automatically come on when either door is opened and
it is dark outside.
Press the lens to turn on the lights manually. Press it
again to turn them off.
If the reading lights are left on, they automatically shut
off 10 minutes after the ignition has been turned 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 either door is opened, the trunk is opened or the
courtesy lamps are turned on.
Storage Mode Personalization
This feature is for long-term use and must be
programmed through the Driver Information
Center (DIC). This feature protects the battery by
placing your vehicle in a storage mode so that the radio,
amplifiers, instrument panel 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 and OnStar

Your vehicle has an electrochromic inside rearview mirror
with a compass. Your vehicle's mirror also contains
OnStar

buttons. For more information about OnStar,
see ªOnStarº in the Index.
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.

dimming feature will be active each time the vehicle
is started.
Compass Operation
Press the on/off button 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.
Compass Calibration
If after two seconds, the display does not show a
compass heading (N 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. If the letter C should ever appear in the compass
window, the compass may need calibration.

2-57
OnStar will not function if the vehicle's battery is
discharged or disconnected. It may also be inoperative
if the vehicle is in an accident and the OnStar or vehicle
electrical system components are damaged.
OnStar is the communication link between you and
existing governmental emergency and roadside service
providers. OnStar will receive your call and use
reasonable effort to contact an appropriate provider.
OnStar cannot promise the providers will respond in
a timely manner or at all.
