2003 Buick Park Avenue Owner ManualM

{CAUTION:
When an air bag in¯ates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is safe
to do so. If you have breathing problems but
can't get out of the vehicle after an air bag
in¯ates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an air bag deployment, you
should seek medical attention.
In many crashes severe enough to in¯ate 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 in¯ate only once. After an
air bag in¯ates, 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 bagmodules 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
in¯ation and driver's safety belt usage at
deployment. The module also records speed,
engine rpm, brake and throttle data.
·Let only quali®ed 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.

Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service
manual have information about servicing your vehicle
and the air bag systems. To purchase a service manual,
see
Service Publications Ordering Information on
page 7-9.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
air bag can still in¯ate during improper
service. You can be injured if you are close to
an air bag when it in¯ates. Avoid yellow
connectors. They are probably part of the air
bag systems. Be sure to follow proper service
procedures, and make sure the person
performing work for you is quali®ed to do so.
The air bag systems do not need regular maintenance.
Restraint System Check
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

Remote Keyless Entry System
If equipped, the remote keyless entry system operates
on a radio frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modi®cations to this system by other than
an authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
·Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
·Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
·Check to determine if battery replacement or
resynchronization is necessary. See ªBattery
Replacementº and ªResynchronizationº under
ªRemote Keyless Entry System Operationº following
this section.
·If you are still having trouble, see your dealer or a
quali®ed technician for service.
Remote Keyless Entry System
Operation
If your vehicle has this feature, you can lock and unlock
your doors or unlock your trunk from about 3 feet (1 m)
up to 30 feet (9 m) away using the remote keyless
entry transmitter supplied with your vehicle.
The numbers on the back of the transmitters correspond
to DRIVER #1 and DRIVER #2 on the DIC (if equipped).
See
Driver Information Center (DIC) on page 3-43for
more information.
2-5

Remember, the theft-deterrent system won't activate if
you lock the doors with a key or use the manual
door lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that
you can start your vehicle with the correct ignition key if
the alarm has been set off.
Here's how to avoid setting off the alarm by accident:
·If you don't want to activate the theft-deterrent
system, the vehicle should be locked with the door
key
afterthe doors are closed.
·Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any
other way will set off the alarm.
If you set off the alarm by accident, unlock any door
with your key. You can also turn off the alarm by
pressing the unlock button on the remote keyless entry
transmitter. The alarm won't stop if you try to unlock
a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, roll down the driver's
window and open the driver's door.
2. Activate the system by locking the doors using the
power door lock switch while the door is open, or
using the remote keyless entry transmitter.
3. Get out of the car, close the door and wait for the
SECURITY light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should, but the
vehicle's lamps ¯ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
see
Fuses and Circuit Breakers on page 5-87.
If the alarm does not sound or the vehicle's lamps do
not ¯ash, the vehicle should be serviced by an
authorized service center.

PASS-KeyžIII
Your PASS-KeyžIII system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired
operation.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modi®cations to this system by other than
an authorized service facility could void authorization to
use this equipment.
PASS-Key
žIII uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
PASS-KeyžIII Operation
Your vehicle is equipped
with the PASS-KeyžIII
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
žIII is a passive
theft-deterrent system.
This means you don't have
to do anything different
to arm or disarm the
system. It works when you
insert or remove the key
from the ignition.
When the PASS-Key
žIII system senses that someone
is using the wrong key, it shuts down the vehicle's
starter and fuel systems. The starter will not work and
fuel will stop being delivered to the engine. Anyone
using a trial-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
When trying to start the vehicle, if the engine does not
start and the SECURITY light comes on, the key
may have a damaged transponder. Turn the ignition off
and try again.
2-19

If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse. See
Fuses
and Circuit Breakers on page 5-87. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the ®rst key may be
faulty. See your dealer who can service the
PASS-Key
žIII to have a new key made.
It is possible for the PASS-Key
žIII decoder to learn the
transponder value of a new or replacement key. Up
to 10 additional keys may be programmed for the
vehicle. This procedure is for programming additional
keys only.
Canadian Owners:If you lose or damage your keys,
only a GM dealer can service PASS-Key
žIII to
have new keys made. To program additional keys you
will need two current driver's keys. You must add a step
to the following procedure. After Step 2, repeat
Steps 1 and 2 with the second current driver's key. Then
continue with Step 3.To program the new key, do the following:
1. Verify that the new key has PK3
žstamped 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
žIII system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key
žIII system at this time.
If you lose or damage a PASS-Key
žIII, see your dealer
to have a new key made.
2-20

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.Key Reminder Warning
If you leave your key in the ignition, with the engine off,
you will hear a warning chime when you open the
driver's door.
Retained Accessory Power (RAP)
After you turn the ignition off and remove the key, you
will still have power to such accessories as the
radio, sunroof (option) and power windows for up to
10 minutes. Power is stopped if you open a door.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position ± that's a
safety feature. To restart when you're already moving,
use NEUTRAL (N) only.
Notice:Don't try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transaxle. Shift to PARK (P) only when your
vehicle is stopped.
1. With your foot off 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.
2-22

Outside Convex Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
Outside Automatic Dimming
Heated Mirror
If you have this feature, the driver's side outside
rearview mirror will adjust for the glare of headlamps
behind you. This feature is controlled using the on and
off settings on the automatic dimming rearview mirror.
See ªAutomatic Dimming Rearview Mirrorº or ªAutomatic
Dimming Rearview Mirror with Compassº earlier in
this section.If you have this feature, the left and right outside mirrors
are also heated when you activate the rear window
defogger. See ªRear Window Defoggerº under
Dual Automatic Climate Control System on page 3-22.
Both outside mirrors can be folded forward or rearward.
In the rearward position, they will fold ¯ush with the
vehicle. This feature is particularly useful in automatic
car washes.
