ECU BUICK PARK AVENUE 2005 Owner's Guide

{CAUTION:
Both frontal and side impact airbags inate
with great force, faster than the blink of an eye.
If you are too close to an inating airbag, as you
would be if you were leaning forward, it could
seriously injure you. Safety belts help keep you
in position for airbag ination before and during
a crash. Always wear your safety belt, even with
frontal airbags. The driver should sit as far back
as possible while still maintaining control of the
vehicle. Front occupants should not lean on or
sleep against the door.
{CAUTION:
Anyone who is up against, or very close to,
any airbag when it inates can be seriously
injured or killed. Airbags plus lap-shoulder
CAUTION: (Continued)
CAUTION: (Continued)
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle’s safety belt system nor its airbag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,
see the part of this manual called “Older
Children” or “Infants and Young Children.”
There is a airbag readiness
light on the instrument
panel cluster, which shows
the airbag symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAirbag Readiness Light on page 3-36
for more information.

Rear Door Security Locks
Your vehicle may have
rear door security locks
that prevent passengers
from opening the rear
doors of your vehicle from
the inside.
To use one of these locks, do the following:
1. Open the rear door you want to lock.
2. Move the lever located on the inside door edge, all
the way to the lock symbol.
3. Close the door.
4. Do the same thing to the other rear door lock.
The rear doors of your vehicle cannot be opened from
the inside when this feature is in use.
To open a rear door when the security lock is on, do
the following:
1. Unlock the door.
2. Open the door from the outside.If you do not cancel the security lock feature, adults or
older children who ride in the rear seat will not be
able to open the rear door from the inside. You should
let adults and older children know how these security
locks work, and how to cancel the locks.
To cancel the rear door lock, do the following:
1. Unlock and open the door from the outside.
2. Move the lever all the way to the unlock symbol.
3. Do the same for the other rear door.
The rear door locks will now work normally.
Lockout Protection
The power door locks will not work if the key is left in
the ignition and the driver’s door is open. You can
override this feature by holding the power door lock
switch on the driver’s door for more than three seconds.
Leaving Your Vehicle
If you are leaving the vehicle, take your key, open your
door and set the locks from inside or with the remote
keyless entry transmitter. Then get out and close
the door.

Remote Trunk Release Lockout
The remote trunk release lockout switch allows you to
secure items in the trunk.
Insert the ignition key into
the TRUNK switch, located
to the left of the steering
column. Turn the key
one-quarter turn clockwise
to LK then remove it
from the switch.
This will disable the trunk release button and prevent
the trunk from opening when this button is pressed.
Trunk Security Override
The remote keyless entry transmitter will open the trunk
when the ignition is on or off and the vehicle is in
PARK (P), even if the trunk release lockout is activated.
Emergency Trunk Release Handle

as a tie-down or anchor point when securing
items in the trunk may damage it. Use the

handle located near the trunk latch. This handle will glow
following exposure to light. Pull the release handle up
to open the trunk from the inside.

Sun Visors
Lighted Visor Vanity Mirror
If your vehicle has this feature, when you open the visor
vanity mirrors, the lamps turn on.
To block out glare, swing down the visors. The larger
sun visor can be removed from the center mount
and moved to the side, while the auxiliary sun visor
remains to block glare from the front.
The front side of the driver’s sun visor also contains a
pocket for map storage.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle is equipped with a content theft-deterrent
alarm system. With this system, the SECURITY light will
ash as you open the door if your ignition is off.
This light reminds you to activate the theft-deterrent
system. Here’s how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The
SECURITY light should come on and stay on.
3. Close all doors. The SECURITY light should go off
after approximately 30 seconds. The alarm is not
armed until the SECURITY light goes off.United States
Canada
2-18

If a door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. Your
vehicle’s lamps will ash and the horn will sound
for 30 seconds. The lamps and horn will then turn off to
save battery power.
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 key if the
alarm has been set off.
Here’s how to avoid setting off the alarm by accident:
If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the
door keyafterthe 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,
seeFuses and Circuit Breakers on page 5-92.
If the alarm does not sound or the vehicle’s lamps do
not ash, the vehicle should be serviced by a GM dealer.

PASS-Key®III
Your PASS-Key®III 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 modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
PASS-Key
®III uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
PASS-Key®III Operation
Your vehicle is equipped
with the PASS-Key®III
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
®III 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
®III 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.
2-20

If the engine still does not start, and the key appears to
be undamaged, try another key. At this time, you
may also want to check the fuse. SeeFuses and Circuit
Breakers on page 5-92. 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
®III to
have a new key made.
It is possible for the PASS-Key
®III 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
®III 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 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 GM dealer for service.3. After the engine has started, turn the ignition 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 GM 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
GM dealer to have a new key made.
