2004 BUICK PARK AVENUE brake

In many crashes severe enough to inate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the right front passenger air bag.
Air bags are designed to inate only once. After an
air bag inates, you’ll need some new parts for
your air bag system. If you don’t get them, the air
bag system won’t be there to help protect you
in another crash. A new system will include air bag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
Your vehicle is equipped with a crash sensing and
diagnostic module, which records information
about the frontal air bag system. The module
records information about the readiness of the
system, when the system commands air bag
ination and driver’s safety belt usage at
deployment. The module also records speed,
engine rpm, brake and throttle data.
Let only qualied technicians work on your air bag
systems. Improper service can mean that an air
bag system won’t work properly. See your dealer
for service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, or the air
bag covering on the driver’s and right front
passenger’s seatback, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right front
passenger’s air bag, or both the air bag module
and seatback for the driver’s and right front
passenger’s side impact air bag. Do not open or
break the air bag coverings.

To program the new key, do the following:
1. Verify that the new key has PK3 stamped on it.
2. Insert the current driver’s key in the ignition
and start the engine. If the engine will not start,
see your dealer for service.
3. After the engine has started, turn the key to OFF,
and remove the key.
4. Insert the key to be programmed and turn it to RUN
within 10 seconds of removing the previous key.
5. The SECURITY light will turn off once the key has
been programmed. It may not be apparent that the
SECURITY light went on due to how quickly the
key is programmed.
6. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the SECURITY light comes
on and stays on, you will be able to restart your
engine if you turn it off. Your PASS-Key
®III system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key
®III system at this time.
If you lose or damage a PASS-Key
®III, see your dealer
to have a new key made.
Starting and Operating
Your Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
“break-in.” But it will perform better in the long run
if you follow these guidelines:
Do not drive at any one speed — fast or
slow — for the rst 500 miles (805 km).
Do not make full-throttle starts.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new brake
linings are not yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this breaking-in guideline
every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing a
Trailer on page 4-38for more information.

Ignition Positions
With the key in the ignition switch, you can turn to ve
different positions.
A (ACCESSORY):In this position you can operate your
electrical accessories. Press in the ignition switch as
you turn the top of it toward you.
B (LOCK):This is the only position from which you can
remove the key. This position locks your ignition,
steering wheel and transaxle. It’s a theft-deterrent
feature.Notice:If your key seems stuck in LOCK and you
can’t turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the key
hard. Turn the key only with your hand. Using a
tool to force it could break the key or the ignition
switch. If none of these works, then your vehicle
needs service.
C (OFF):This position lets you turn off the engine but
still turn the steering wheel. It doesn’t lock the
steering wheel like LOCK and it doesn’t send any power
to the accessories. The instrument panel cluster will
remain powered in OFF to illuminate the gear shift
indicator. The cluster will also activate the parking brake
light when the parking brake is set. Use OFF if you
must have your vehicle in motion while the engine is not
running.
D (RUN):This is the position that the switch returns to
after you start your engine and release the ignition
key. This is the position for driving. Even when
the engine is not running, you can use RUN to operate
your electrical accessories and to display some
instrument panel warning lights.
E (START):This position starts your engine. When the
engine starts, release the ignition key. The switch
will return to RUN for normal driving.
2-24

Automatic Transaxle Operation
Your automatic transaxle has a shift lever located on
the steering column.
PARK (P):This position locks your front wheels.
It’s the best position to use when you start your engine
because your vehicle can’t move easily.
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
CAUTION: (Continued)
CAUTION: (Continued)
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle will not move, even when you are on
fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
SeeShifting Into Park (P) on page 2-30.Ifyou
are pulling a trailer, seeTowing a Trailer on
page 4-38.
Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transaxle
shift lock control system. You have to fully apply
your regular brakes before you can shift from PARK (P)
when the ignition is in RUN. If you cannot shift out of
PARK (P), ease pressure on the shift lever and push the
shift lever all the way into PARK (P) as you maintain
brake application. Then move the shift lever into
the gear you wish. SeeShifting Out of Park (P) on
page 2-33.
2-27

REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transaxle.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transaxle, see
If You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-30.
NEUTRAL (N):In this position, your engine doesn’t
connect with the wheels. To restart when you’re already
moving, use NEUTRAL (N) only. Also, use NEUTRAL (N)
when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine racing may damage the transaxle.
The repairs would not be covered by your warranty.
Be sure the engine is not racing when shifting
your vehicle.
AUTOMATIC OVERDRIVE (
X):This position is for
normal driving. If you need more power for passing,
and you’re:
Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You’ll shift down to the next gear and have more power.
THIRD (3):This position is also used for normal
driving. However, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (
X).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (
X):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
When going down a steep hill.
2-28

SECOND (2):This position gives you more power but
lower fuel economy than THIRD (3). You can use
SECOND (2) on hills. It can help control your speed as
you go down steep mountain roads, but then you
would also want to use your brakes off and on.
Notice:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transaxle. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or AUTOMATIC
OVERDRIVE (D) instead of SECOND (2).
FIRST (1):This position gives you even more power
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
shift lever is put in FIRST (1), the transaxle won’t shift
into rst gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.Parking Brake
This vehicle has a PUSH
TO RELEASE parking
brake pedal. To set the
parking brake, hold
the regular brake pedal
down with your right foot.
Push down the parking
brake pedal with your
left foot.
Whether the ignition key is in RUN or OFF, the brake
system warning light stays on while the parking brake
is set.
The parking brake uses the brakes on the rear wheels.
To release the parking brake, hold the regular brake
pedal down and push the parking brake pedal with your
left foot. When you lift your left foot, the parking brake
pedal will follow it to the release position.
2-29

If you try to drive with the parking brake on, after about
20 feet (6.1 m) a chime will sound continuously until
you release the parking brake. Also, the brake light will
stay on until the parking brake is released.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-38. That part shows
what to do rst to keep the trailer from moving.Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle will
not move, even when you are on fairly level
ground, use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 4-38.
