2000 CADILLAC SEVILLE battery

2-10 Resynchronization
Pressing the transmitter buttons numerous times
(approximately 250 times) out of the vehicle's operating
range may cause the transmitter not to work. Replacing
the battery and pressing the transmitter buttons out
of range will also cause the transmitter not to work.
If only the fuel door button works, the transmitter needs
to be resynchronized to the receiver. Do this by pressing
and holding both the lock and unlock buttons on the
transmitter for about eight seconds. You must be within
range of the vehicle.
Once the transmitter has been resynchronized, the horn
will sound and the exterior lamps will flash once. The
system should now operate properly. See your dealer for
service if your transmitter still doesn't work properly.
Trunk
CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on AUTO and the temperature between
65F (18C) and 85F (29C). That will
force outside air into your vehicle.
See ªComfort Controlsº in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.

2-20 Starting Your Northstar V8 Engine
1. Without pushing the accelerator pedal, turn your
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive
heat can damage your starter motor. Wait about
15 seconds between each try to help avoid
draining your battery or damaging your starter.
2. If it doesn't start right away, hold your key in
START for about three seconds at a time until your
engine starts. Wait about 15 seconds between each
try to help avoid draining your battery or damaging
your starter.3. If your engine still won't start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
briefly but then stops again, do the same thing.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.
If you ever have to have your vehicle towed,
see the part of this manual that tells how to do
it without damaging your vehicle. See ªTowing
Your Vehicleº in the Index.

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 lamps will come 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 lamps control knob to
turn the lamps back on. To delay the lamps from
turning off, see ªTwilight Sentinelº in the Index.

2-49 Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the driver's door switches
and to the ignition key when a door is opened or if you
press the Remote Keyless Entry (RKE) transmitter
unlock button. The illuminated entry system works with
the light sensor and it must be dark outside in order
for the courtesy lamps or backlighting to turn on. The
courtesy lamps turn off approximately 25 seconds after
the last door is closed or after the ignition key is turned
to RUN or if the RKE transmitter lock button is pressed.
The courtesy lamps turn off approximately 40 seconds
after the doors are unlocked with the RKE transmitter
if no door is opened.
Parade Dimming
This feature prohibits the dimming of the instrument
panel lights during daylight while the parking lamps are
on. This feature works with the light sensor and is fully
automatic. When the light sensor reads darkness outside,
the instrument panel lights can be adjusted by following
the steps under ªInstrument Panel Intensity/Brightness
Control.º Backlighting to the instrument panel will
also turn on.
Reading Lamps
The reading lamps are located in the roof. These lamps
and the interior courtesy lamps come on when any door
is opened and it is dark outside. The rear lamps come on
when a rear door is opened. Press the button near the
lamps to turn them 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, high blower fan, heated seats and engine
cooling fans.

2-50
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 blower 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. 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
Your vehicle has an electrochromic inside rearview
mirror with a compass.
By pressing the MIRROR side of the button located
at the bottom of the mirror, the mirror automatically
changes to reduce glare from headlamps behind you.

Power to the cigarette lighter will shut off 10 minutes
after the ignition is turned off. This helps to prevent
battery drainage. For more information, see ªInadvertent
Power Battery Saverº in the Index.
NOTICE:
Don't hold a cigarette lighter in with your hand
while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.

2-57
Sun Visors
Swing down the visor to block out glare. It can be
detached from the center mount and moved to the side.
When moved to the side, the sun visor will also move
forward and rearward. The sun visors are equipped with
a storage flap that can be used for small items such as
toll tickets.
There is also a secondary visor attached separately to
the headliner.
Lighted Visor Vanity Mirror
Turn the sunshade down and lift the cover to see the
mirror. Move the slide switch up or down to brighten or
dim the lamp.
Accessory Power Outlets
The accessory power outlets are located at the rear of
the center console and on the lower inboard carpeted
panel on the passenger's side of the vehicle. When the
ignition is on, you can plug in accessories that require
electrical power.Don't leave your vehicle when the engine is running
unless you have to. If you have left the engine running,
the vehicle can move suddenly.
If you use the accessory power outlets for more than
10 minutes after turning off your engine, you will risk
running your battery down. For more information about
accessory power outlets, contact your dealer.
Cellular Telephone (Option)
Your vehicle has been prewired for dealer installation of
a Cadillac Communiport
integrated portable cellular
telephone system. If your vehicle is already equipped
from the factory with this option, your vehicle is
prepared to receive a completion kit to finalize the
installation at the dealer. The system has steering wheel
telephone controls and information output through the
Driver's Information Center (DIC). Voice activation,
memo record and hands
-free operation are standard
features. For more information, contact your dealer.
A user's guide is provided with the telephone.

2-71 Charging System Light
This light goes on when
you turn your key to ON
or START. It goes off once
you start your engine.
That's a check to be sure the light works. If it doesn't
come on, be sure to have it fixed so it will be there to
warn you if something goes wrong.
If this light stays on, you need service and you should
take your vehicle to the dealer at once. To save your
battery until you get there, turn off all accessories.
Brake System Warning and Park Brake
Indicator Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on
briefly when you turn the
ignition key to ON. If it
doesn't come on then,
have it fixed so it will be
ready to warn you if
there's a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. (See ªTowing Your Vehicleº
in the Index.)
CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you've
pulled off the road and stopped carefully, have
the vehicle towed for service.
