2004 BUICK REGAL key battery

Shifting Out of Park (P)
The vehicle has an automatic transaxle shift lock control
system which locks the shift lever in PARK (P) when the
ignition is in the OFF position. The regular brakes must
be fully applied before the vehicle can be shifted from
PARK (P) when the ignition in RUN. SeeAutomatic
Transaxle Operation on page 2-21.
If the vehicle cannot be shifted out of PARK (P), ease
pressure on the shift lever and push the shift lever all the
way into PARK (P) as brake application is maintained.
Then, move the shift lever into the desired gear.
If the brake pedal is pressed down but the vehicle still
cannot be shifted out of PARK (P), try this:
1. Turn the ignition key to ACCESSORY. There is no
shift interlock in this key position.
2. Apply and hold the brake until the end of Step 4.
3. Shift the transaxle to NEUTRAL (N).
4. Start the engine and then shift to the desired gear.
5. Have the system xed as soon as possible.
Shift Lock Release
The vehicle is equipped with a shift lock release system.
It is designed to prevent ignition key removal unless
the shift lever is in PARK (P) and the shift lever button
is fully released.
It also prevents the shift lever from moving out of
PARK (P) when the ignition is in OFF or in LOCK. The
shift lock release system will not operate in the case
of a dead or low voltage (less than 9 V) battery.
If the vehicle has a dead battery or a battery with low
voltage, there are two override access slots that
will allow you to override the shift lock release system.
The rst access slot is located underneath the
steering column below the lock cylinder. To use this
slot, do the following:
1. Verify that the shift lever is in PARK (P) with the
shift lever button released.
2. Remove the override access slot cap to show the
override mechanism release button.
3. Insert a key or tool into the access slot and then
press and hold the override mechanism release
button.
4. Turn the ignition key to OFF.
5. Remove the key from the ignition switch.
6. Put the override access slot cap back on.

Charging System Light
The charging system light
will come on briey when
the ignition is turned
on, as a check to show
that it is working. Then it
should go out.
If it stays on, or comes on while the vehicle is being
driven, there may be a problem with the charging
system. It could indicate that the vehicle has a loose
accessory belt or another electrical problem. Have
it checked right away. Driving while this light is on could
drain the battery.
If the vehicle must be driven a short distance with the
light on, be certain to turn off all the accessories,
such as the radio and air conditioner.
Brake System Warning Light
The vehicle’s hydraulic brake system is divided into two
parts. If one part is not working, the other part can
still work and stop the vehicle. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
This light should come on briey when the ignition key is
turned to RUN. If it does not come on then, have it xed
so it will be ready to warn you if there is a problem.

CD Messages
CHECK CD:If this message appears on the radio
display, it could be for one of the following reasons:
It is very hot. When the temperature returns to
normal, the CD should play.
You are driving on a very rough road. When the
road becomes smooth, the CD should play.
The CD is dirty, scratched, wet, or upside down.
The air is very humid. If so, wait about an hour and
try again.
There may have been a problem while burning
the CD.
The label may be caught in the CD player.
If the CD is not playing correctly, for any other reason,
try a known good CD.
If any error occurs repeatedly or if an error cannot be
corrected, contact your dealer. If your radio displays an
error message, write it down and provide it to your
dealer when reporting the problem.
Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is removed and the
radio is placed in a different vehicle. This feature
requires no user input to be activated. It is automatically
armed when it is put into the vehicle for the rst time.
When the ignition is turned off, the blinking red light
indicates that THEFTLOCK
®is armed.
If THEFTLOCK
®is activated, your radio will not operate
if stolen. The radio will display LOCKED and a red
LED indicator light will come on above the key symbol
to indicate a locked condition. If this occurs, the radio will
need to be returned to the dealer.

Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your
vehicle was designed and tested with top-quality GM
brake parts. When you replace parts of your braking
system — for example, when your brake linings
wear down and you need new ones put in — be sure
you get new approved GM replacement parts. If you do
not, your brakes may no longer work properly. For
example, if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change — for the worse. The braking
performance you have come to expect can change
in many other ways if someone puts in the wrong
replacement brake parts.
Battery
Your new vehicle comes with a maintenance free
ACDelco®battery. When it is time for a new battery, get
one that has the replacement number shown on the
original battery’s label. We recommend an ACDelco
®
battery. SeeEngine Compartment Overview on
page 5-12for battery location.
Warning:Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.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
Shifting Out of Park (P) on page 2-27.
Vehicle Storage
If you are 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
are not careful. SeeJump Starting on
page 5-47for 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, seeTheft-Deterrent
Feature on page 3-61.
