fog light CADILLAC DEVILLE 2002 8.G Owners Manual

2-52
When DRL are on, only your high-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.
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.
If it's 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.

2-53
Fog Lamps (If Equipped)
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 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'll 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.

2-55
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 exterior
lamps or the HEADLAMPS SUGGESTED message
will be on 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
ten 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 ªTwilight Sentinelº in the Index.

2-58
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 ªBattery
Saver Active Messageº in the Index.
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.

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:
Don't use the Night Vision System to replace
your normal view of the road ahead. It can't 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 don't
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.
