2005 BUICK LACROSSE lock

Automatic Door Locks
The vehicle’s doors are programmed from the factory to
lock when the shift lever is moved into a forward
gear, and to unlock when the shift lever is moved into
PARK (P).
If someone needs to get in or out of the vehicle after
the doors have been locked, place the shift lever
into PARK (P). You may also unlock all doors using the
power door lock switch or unlock one door using the
inside manual door lock.
If your vehicle has a Driver Information Center (DIC),
there are different programming options for locking and
unlocking the doors automatically. SeeDIC Vehicle
Personalization on page 3-71.
Lockout Protection
The lockout protection feature makes it more difficult to
lock the key in the vehicle. If the driver’s door is
open while the key is in the ignition, the door cannot be
locked with the power door lock switch.
This feature cannot guarantee that you will never be
locked out of the vehicle. If the key is not left in
the ignition, or, if the manual door lock pin is used, the
key could still be locked inside the vehicle. Always
remember to take the key with you.

Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-30.
Trunk Lock
To unlock the trunk from the outside, use the remote
keyless entry transmitter. SeeRemote Keyless
Entry System Operation on page 2-4for more
information.
The ignition must be off, or the transaxle must be in
PARK (P), to unlock the trunk.
Remote Trunk Release
This feature is used to unlock the trunk from inside the
vehicle using the power door lock switch.
Press and hold the top of
the driver’s or front
passenger’s power
door lock switch for
one and one-half seconds
to unlock the trunk.
The vehicle must be in PARK (P) to unlock the trunk.

Power Windows
The switches on the driver’s door armrest are used to
control each of the windows. The power window
switches work while the ignition is on, in ACCESSORY,
or while Retained Accessory Power (RAP) is active.
SeeRetained Accessory Power (RAP) on page 2-22.
Each passenger door has its own window switch.
To lower the window, press and hold the front of the
switch to the rst position until the window is at
the desired level. To raise the window, pull up and hold
the front of the switch.
Express-Down Window
The driver’s window switch has an express-down
feature labeled AUTO. This allows you to lower the
window completely without holding the switch. Press the
front of the switch all the way down and release.
To stop the window while it is lowering, briey pull up
on the switch.
Window Lockout
o
(Window Lockout):The driver’s window switches
also include a lockout switch. Press the right side of
the switch to prevent the rear passengers from
using their window switches. The driver can still control
all the windows and the front passenger can control
their own window with the lockout on. Press the left side
of the switch to return to normal window operation. A
red bar on the right side of the switch will indicate
that the lockout is off.

Sun Visors
To block out glare, you can swing down the visors and
slide them along the rod to cover different areas of
the front window. You can also move them to cover the
side windows.
Visor Vanity Mirror
Swing down the sun visors and lift the cover to expose
the vanity mirror. If your vehicle has lighted vanity
mirrors, the light will come on when you lift the cover.
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 may have a content theft-deterrent
alarm system.
A red light located on top of
the instrument panel,
toward the center of the
vehicle and near the
windshield, will ash slowly
when the system is armed.
The theft-deterrent alarm system needs to be activated
through the Driver Information Center (DIC). See
“CONTENT THEFT” under “Customization Menu Items”
inDIC Vehicle Personalization on page 3-71. While
armed, the doors will not unlock with the power door lock
switch. The remote alarm will sound if someone
tampers with the trunk, enters the vehicle without using
the remote keyless entry transmitter or key to unlock
the doors, or turns the ignition on without the proper key.
The horn will sound and the headlamps will ash for
up to two minutes. The system will also cut off the fuel
supply, preventing the vehicle from being driven.
2-17

Arming with the Power Lock Switch
The vehicle’s content theft-deterrent alarm system can
be activated when the key is removed from the
ignition and the power door lock switch of either the
driver’s or front passenger’s door is used to lock
the vehicle. The door needs to be in the open position
when pressing the power door lock switch. The
alarm system will not activate if the door is closed when
the power door lock switch is pressed. This system
can be activated through the Driver Information
Center (DIC). See “CONTENT THEFT” under
“Customization Menu Items” inDIC Vehicle
Personalization on page 3-71.
When the doors are locked using the power door lock
switch of either front door, the red light on top of
the instrument panel will start ashing at a fast rate,
indicating that the system is arming. After all the doors
are locked there will be a time delay and then the
red light will begin to ash at a very slow rate, indicating
the system is armed.
Arming with the Remote Keyless Entry
Transmitter
The alarm system will arm when the remote keyless
entry transmitter is used to lock the doors after the key
is removed from the ignition. The red light will comeon to indicate that the system is arming. After all doors
are closed and locked, and after a time delay, the
red light will begin ashing at a very slow rate to show
the system is armed.
Arming Conrmation
A red light located on top of the instrument panel,
towards the center of the vehicle and near the
windshield, will ash slowly to conrm when the system
is armed.
Disarming with the Remote Keyless
Entry Transmitter
The alarm system will disarm when the remote keyless
entry transmitter is used to unlock the doors. The
red light will go out to show that the system is disarmed.
Disarming with Your Key
The alarm system will disarm when the key is used to
unlock the doors. The red light will stop ashing
when the system is disarmed. If you would like the key
to disarm the alarm system, see “CONTENT THEFT”
underDIC Vehicle Personalization on page 3-71
for more information.

When trying to start the vehicle, if the engine does not
start and the STARTING DISABLED warning message
on the Driver Information Center (DIC) comes on,
the key may have a damaged transponder. Turn the
ignition off and try again.
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. SeeFuses
and Circuit Breakers on page 5-88. If the engine still
does not start with the other key, the vehicle needs
service. If the 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. In an
emergency, contact Roadside Assistance. SeeRoadside
Assistance Program on page 7-6for more information.
It is possible for the PASS-Key
®III decoder to accept
the transponder value of a new or replacement key. Up
to 10 keys may be programmed for the vehicle. The
following procedure is for programming additional keys
only. If all the programmed keys are lost or do not
operate, see your dealer or a locksmith who can service
PASS-Key
®III to have keys made and programmed
to the system.To program the new key do the following:
1. Verify that the new key has PK3 stamped on it.
2. Insert the master 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 ve seconds of removing the original key.
5. The STARTING DISABLED warning message on
the DIC will turn off, once the key has been
programmed. It may not be apparent that the
STARTING DISABLED warning message went on
due to how quickly the key is programmed.
6. Repeat Steps 1 through 5 if additional keys are to
be programmed.
If the STARTING DISABLED warning message appears
and stays on the DIC while the vehicle is being
driven, the engine will be able to be restarted if it is
turned off. Your PASS-Key®III system, however, is not
working properly and must be serviced by your
dealer. The vehicle is not protected by the
PASS-Key
®III system at this time.
If the PASS-Key
®III key is lost or stolen, see your
dealer or a locksmith who can service PASS-Key®III 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 4-35for more information.
Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
A (OFF):This is the only position in which the ignition
key can be inserted or removed. This position locks
the ignition and transaxle. It is a theft-deterrent feature.
B (ACCESSORY):This position lets the radio and
windshield wipers operate while the engine is off. To use
ACCESSORY, turn the key clockwise.
2-21

C (RUN):This position is where the key returns to after
the vehicle is started. This position displays some of
the warning and indicator lights.
D (START):This position starts the engine.
A warning chime will sound and the Driver Information
Center will display a warning message when the driver’s
door is opened if the ignition is in OFF, LOCK or
ACCESSORY and the key is in the ignition. SeeDIC
Warnings and Messages on page 3-53for more
information.
Retained Accessory Power (RAP)
If the vehicle has Retained Accessory Power (RAP),
certain features will continue to operate for up to
10 minutes after the ignition key is turned to OFF unless
a door is opened.
Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
The engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as the
engine gets warm.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
