2000 BUICK REGAL key battery

2-31 Shift Lock Release
Your vehicle is equipped
with an electric park lock
system. The system is
designed to prevent ignition
key removal unless the
shift lever is in PARK (P)
(with the shift knob button
fully released).
The system also prevents the shift lever from moving
out of PARK (P) when the ignition is in OFF or in
LOCK. The park lock system is always functional
except in the case of a dead or low voltage (less than
9 V) battery.
If your vehicle has a dead battery or a battery with low
voltage, there are two override access slots that will
allow you to override the park lock system.The first access slot is located underneath the steering
column below the lock cylinder. To use this slot:

Verify that the shift lever is in PARK (P) (with the
shift knob button released.)

Remove the override access slot cap, which will then
show the override mechanism release button.

Insert a key or screwdriver into the access slot and
then press in and hold the override mechanism
release button.

Turn the ignition key to OFF.

Remove the key from the ignition switch.

Put the override access slot cap back on.
You will not be able to remove your key from the
ignition unless the shift lever is in PARK (P) with the
shift knob button fully released.
The second override access slot is located on the upper
right side of the shift panel. To use this slot:

Remove the override access slot cap.

Insert a key or screwdriver into the access slot, press
in and hold the override mechanism release button.

Pull the shift lever into the desired gear position.

Reinstall the override access slot cap back on.

After releasing the door unlock switch, a single chime
will be heard if the delayed headlamp illumination
function has been disabled; two chimes will be heard

programmed operation of this feature.
Fog Lamps
To turn the fog lamps on,
press the fog lamps switch
located below the headlamp
switch on the left side of the
steering column.
A light will glow on the switch to let you know that the
fog lamps are on. (Your parking lamps or low
-beam
headlamps must be on or your fog lamps won't come
on.) Press the switch again to turn the fog lamps off.
The fog lamps will go off whenever you change to
high
-beam headlamps. When you return to low beams,
the fog lamps will come on again.
Cornering Lamps
The cornering lamps are designed to come on when you
signal a turn. This will provide more light for cornering
at night.

Instrument Panel Brightness Control
You can brighten or dim the instrument panel lights by
moving the LIGHTS dial. If you turn the dial past

Courtesy Lamps
When any door is opened, several lamps come on.
These lamps are courtesy lamps. They make it easy for
you to enter and leave your vehicle. You can also turn
these lamps on by twisting or turning the interior lights
knob all the way to the right.
Illuminated Entry
Your courtesy lamps will come on and stay on for a set
time whenever you press UNLOCK on the remote
keyless entry transmitter.
If you open a door, the lamps will stay on while it's open
and then turn off automatically about 25 seconds after

This will initialize the customization mode. While in the
customization mode, the feature will sound the number
of chimes corresponding to the current mode: In Mode
1, one chime means the feature is disabled. In Mode 2,
two chimes signal that the perimeter lighting feature is
enabled. Each additional press will advance the mode by
one, starting from the current mode. During this
procedure, the feature will sound the number of chimes
corresponding to the mode. When the lock switch is

2-47 Battery Rundown Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave the
interior courtesy lamps, reading/map lamps, visor vanity
lamps, trunk lamp, underhood lamp or glove box lamps
on. If you leave any of these lamps on, they will
automatically turn off after 20 minutes, if the ignition is
in OFF. The lamps won't come back on again until you:

turn the ignition on,

turn the lamp switch off, then on, or

open a door.
Note: If your vehicle has less than 15 miles (25 km) on
the odometer, the battery saver will turn off the lamps
after only three minutes.

With retained accessory power, your power windows,
audio system and sunroof will continue to work up to
10 minutes after the ignition key is turned to OFF and
before any of the doors are opened.

Adjust all the mirrors so you can see clearly when you
are sitting in a comfortable driving position.
Inside Day/Night Rearview Mirror

the bottom of the mirror toward you (to the night
position). To return the mirror back to the day position,
push the lever away from you.

Your vehicle may have an electrochromic day/night
rearview mirror. Push the button in the center of the

gradually to reduce glare from headlamps behind you.
This may take a few moments.
The mirror's two outer buttons operate the lights on the
bottom sides of the mirror.

2-61 Charging System Light
The charging system light
will come on briefly when
you turn on the ignition, as
a check to show you it's
working. Then it should
go out.
If it stays on, or comes on while you are driving, you
may have a problem with the charging system. It could
indicate that you have a loose accessory belt or another
electrical problem. Have it checked right away. Driving
while this light is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.
Brake System Warning 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.
United States Canada
This light should come on briefly when you turn the
ignition key to RUN. 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.)

Battery
Your new vehicle comes with a maintenance free
ACDelco
battery. When it's time for a new battery,
get one that has the replacement number shown on
the original battery's label. We recommend an
ACDelco battery.
If your battery has a very low charge or is dead, you
may not be able to remove the ignition key from the
ignition switch or shift out of PARK (P). Refer to
ªShifting Out of PARK (P)º in the Index.
Vehicle Storage
If you're not going to drive your vehicle for 25 days or
more, remove the black, negative (
-) cable from the
battery. This will help keep your battery from
running down.
CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren't careful. See ªJump Startingº in the Index
for tips on working around a battery without
getting hurt.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
Also, for your audio system, see ªTheft
-Deterrent
Featureº in the Index.
