2002 CADILLAC SEVILLE battery

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.

Programming the HomeLink Transmitter
Do not use the HomeLink Transmitter with any garage
door opener that does not have the ªstop and reverseº
feature. This includes any garage door opener model
manufactured before April 1, 1982.
Be sure that people and objects are clear of the garage
door you are programming.
It is recommended that a new battery be installed in
your hand
-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps
to program up to three channels:
1. Decide which one of the three channels
(one of the HomeLink buttons) you want
to program.
2. Press and hold the desired button on HomeLink
through Step 3.

2-68
3. When the HomeLink indicator light begins to blink
slowly (this may take up to 30 seconds), hold the
hand
-held transmitter about 1 to 3 inches (3 to 8 cm)
away from HomeLink and then press and hold the
transmit button on the hand
-held transmitter.
Continue to hold both buttons until the indicator
light on HomeLink begins to flash rapidly
(this may take up to 90 seconds).
If you have trouble programming HomeLink, make
sure that you have followed the directions exactly as
described and that the battery in the hand
-held
transmitter is not weak. If you still cannot program it,
move the hand
-held transmitter to the left or right or
forward or backward or flip it upside down. HomeLink
may not work with older garage door openers that do
not meet current Federal Consumer Safety Standards.
If you cannot program the transmitter after repeated
attempts, refer to ªTraining a Garage Door Opener
with Rolling Codesº later in this section or contact
the manufacturer of HomeLink at 1
-800-355-3515,
or on the internet at www.homelink.com.
Be sure to keep the original hand
-held transmitter in
case you need to erase and reprogram HomeLink.
Operating the HomeLink Transmitter
Press and hold the appropriate button on HomeLink
for at least half of a second. The indicator light will
come on while the signal is being transmitted.
Training a Garage Door Opener with a
ªRolling Codeº Feature (If Equipped)
If you have not previously programmed the hand-held
transmitter to HomeLink, see ªProgramming the
HomeLink Transmitterº listed previously. If you have
completed this programming already, you now need to
train the garage door opener motor head unit to
recognize HomeLink.
1. Find the ªLearnº or ªSmartº button on the garage
door opener motor head unit. The exact location
and color will vary by garage door opener brand.
If you have difficulty finding the ªLearnº or
ªSmartº button, refer to your garage door opener
owner's manual or contact the manufacturer of
HomeLink at 1
-800-355-3515, or on the internet
at www.homelink.com.
Because of the steps involved, it may be helpful
to have another person assist in programming
the transmitter.
