2002 CADILLAC SEVILLE fog light

2-48 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. Fully
functional daytime running lamps are required on all
vehicles first sold in Canada.
The DRL system will make the high
-beam headlamps
come on at reduced brightness when the following
conditions are met:

It is still daylight and the ignition is on,

the exterior lamp control is in the off position and

the transaxle is not in PARK (P).
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.

2-49 Fog Lamps (STS Only)
Use the fog lamps for better vision in foggy or
misty conditions.
When the ignition is on and you push the fog lamp
button located next to the exterior lamps control,
a small indicator light in the fog lamp button, the
LIGHTS ON and fog lamp indicator lights on the
instrument panel cluster will come on to indicate that
the fog and the parking lamps are on.
Press the fog lamp button again to turn off the
fog lamps.
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.
Twilight Sentinel

This lever is located below
the exterior lamps control.
It automatically turns the
lamps on and off by sensing
how dark it is outside.
To operate the Twilight Sentinel, leave the exterior
lamps control off and slide the TWILIGHT lever to
any position but OFF.
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's dark enough outside and the Twilight Sentinel
lever is off, a HEADLAMPS SUGGESTED message
will display on the Driver Information Center (DIC).

2-50
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 turning the
exterior lamp control to the headlamp position will
remove the HEADLAMPS SUGGESTED message.
Light Sensor
The light sensor for the Daytime Running Lamps (DRL)
and the Twilight Sentinel is located on the driver's side
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.

2-52 Illuminated Entry
The illuminated entry system 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
illuminated entry 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 front reading lamps are located in the overhead
console. These lamps and the interior courtesy lamps
come on when a door is opened and it is dark outside.
The rear reading lamps will not come on when a front
door is opened.
The rear courtesy lamps are located on the rear headliner
above the rear seat outboard positions. When a rear door
is opened, both the front and rear reading lamps come
on with the courtesy lamps.
Press the button near each lamp to turn it on and 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.

2-53
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 Message, Saver Activeº 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.
Mirrors
Electrochromic Day/Night Rearview Mirror
with Compass and OnStar
System
Your vehicle has an electrochromic inside rearview
mirror with a compass display. The mirror also contains
OnStar

controls. For more information see ªOnStarº
in the Index.
(On/Off): The on/off button is located on the
lower left side of the mirror for the electrochromic and
compass functions of the rearview mirror.

2-86 Security Light
For information
regarding this light,
see ªTheft
-Deterrent
Systemº in the Index.
Fog Lamp Light (STS Only)
This light will come on
when the fog lamps are in
use. It will go out when the
fog lamps are turned off.
For more information about
the fog lamps, see ªFog
Lampsº in the Index.
Lights On Reminder Light
United States Canada
This light comes on whenever the parking lamps are on
so that you know that your exterior lamps are on.
Cruise Control Light
This light comes on
whenever the cruise
control system is in use.
It will go out when the
system is turned off.

3-5
If your vehicle is sitting in direct sunlight on a hot day
and you have the climate control system in AUTO, the
air will first flow out the floor ducts for a few seconds.
This is normal. This removes hot air from the air outlets.
As the air is cooled, the airflow will enter the vehicle
through the instrument panel outlets.
To avoid blowing cold air in cold weather, the system
will start at a reduced fan speed until warm air is
available. The length time required for this to happen
depends on the outside air temperature, engine coolant
temperature or the time since the engine was last started.
As the coolant warms up, the fan speed will gradually
increase and air will flow from the floor ducts, with
some airflow to the windshield to prevent fogging under
most normal conditions. If you select defrost mode or a
fan speed manually, this function will be canceled.
If you leave your vehicle, the system will remember
the control setting the next time you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation. Defrost will change to automatic
operation when the ignition is shut off and then turned
back on.Electronic Solar Sensor
The sensor monitors the sun's solar radiation and is located
near the end of the instrument panel near the windshield.
The climate control panel uses this information to
automatically make the necessary temperature and
airflow adjustments to maintain your comfort. The
climate control system may supply cooler air to one side
of your vehicle, if that side is facing the sun.
Be sure not to put anything over the electronic solar
sensor. If you do, the climate control system may not
function properly.

3-7 Rear Window Defogger
The grid lines you see on the rear window warm the
glass. When the rear window defogger is turned on, the
rear window and both outside rearview mirrors are heated
to remove snow and ice from the surface of the glass.
The rear window defogger
button is located on the
climate control panel near
the bottom left corner.
Press the button to turn on the rear defogger. The light in
the button will come on while the system is activated.The system will automatically shut off after 10 minutes.
If further defogging is desired, press the button again.
The system will automatically shut off after five minutes
for any cycles after the initial activation.NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid or the
integrated rear window antenna, and the repairs
wouldn't be covered by your warranty.
The lines along the top of the window are for the diversity
antenna and are not intended to defog the rear window.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
