2009 BUICK LACROSSE Owner's Manual

Power Windows
{CAUTION:
Leaving children in a vehicle with the keys is
dangerous for many reasons, children or others
could be badly injured or even killed. They could
operate the power windows or other controls or
even make the vehicle move. The windows will
function and they could be seriously injured or
killed if caught in the path of a closing window. Do
not leave keys in a vehicle with children.
When there are children in the rear seat use the
window lockout button to prevent unintentional
operation of the 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 in ON/RUN,
ACC/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.
2-15

Express-Down Window
The driver’s window switch has an express-down
feature labeled AUTO. This lets you lower the window
completely without holding the switch. Press the front of
the switch to the second position 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 indicates that the
lockout is off.
Sun Visors
To block out glare, swing down the sun visors. They
can be detached from the center retainer and slid along
the rod to cover different areas of the front window
and turned to cover the side windows.
Visor Vanity Mirror
Swing down the sun visors and lift the cover to expose
the vanity mirror. Do not drive with the cover lifted
due to possible glare impeding other drivers behind or
to the side of the vehicle.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
This vehicle has theft-deterrent features, however,
they do not make it impossible to steal.
2-16

Content Theft-Deterrent
Your vehicle may have a content theft-deterrent alarm
system.
Your vehicle may have a
red light located on top of
the instrument panel,
toward the center of the
vehicle and near the
windshield, that 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 3-74. While
armed, the doors will not unlock with the power door lock
switch. The remote alarm will sound if someone
tampers with the trunk or enters the vehicle without
using the Remote Keyless Entry (RKE) transmitter or
key to unlock the doors. 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.
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 system will
not arm 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 3-74.
When the doors are locked using the power door
lock switch of either front door, the red light, if your
vehicle has one, 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, if your vehicle has one, will begin to ash at a
very slow rate, indicating the system is armed.
2-17

Arming with the RKE Transmitter
The alarm system will arm when the RKE transmitter is
used to lock the doors after the key is removed from
the ignition. The red light, if your vehicle has one,
will come on to indicate that the system is arming. After
all doors are closed and locked, and after a time
delay, the red light, if your vehicle has one, will begin
ashing at a very slow rate to show the system is armed.
Arming Conrmation
Your vehicle may have a red light located on top of the
instrument panel, towards the center of the vehicle
and near the windshield, that will ash slowly to conrm
when the system is armed.
Disarming with the RKE Transmitter
The alarm system will disarm when the RKE transmitter
is used to unlock the doors. The red light, if your
vehicle has one, 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, if your vehicle has
one, 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 3-74for more information.

2-18

PASS-Key®III Electronic
Immobilizer Operation
Your vehicle is equipped with PASS-Key®III
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key
®III is a passive
theft-deterrent system.
The system is automatically armed when the key is
removed from the ignition.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
PASS-Key III
®uses a transponder in the ignition
key that matches a decoder in the vehicle.
When the PASS-Key
®III system senses that the wrong
key has been inserted into the ignition, it shuts down
the vehicle’s starter and fuel systems. The starter will not
work and fuel will stop owing to the engine.If someone tries to start the vehicle again with the
wrong key, the vehicle will not start. Anyone using a
trial-and-error method to start the vehicle will be
discouraged to do so because of the high number of
electrical key codes.
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,
there may be a problem with your theft-deterrent system.
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 5-99. 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/retailer who can service the
PASS-Key®III to have a new key made. In an
emergency, contact Roadside Assistance. SeeRoadside
Assistance Program on page 7-7for more information.
2-19

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/retailer 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/retailer for service.
3. After the engine has started, turn the key to
LOCK/OFF, and remove the key.
4. Insert the key to be programmed and turn it to
ON/RUN within ve seconds of removing the
original key.5. The SERVICE THEFT SYSTEM warning message
on the DIC will turn off, once the key has been
programmed. It may not be apparent that the
SERVICE THEFT SYSTEM 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 SERVICE THEFT SYSTEM 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/retailer. 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/retailer or a locksmith who can service
PASS-Key
®III to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:The 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 constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the 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 4-28for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
Ignition Positions
The ignition switch has
four different positions.
To shift out of P (Park), the ignition must be in ON/RUN
and the brake pedal must be applied.
Notice:Using a tool to force the key to turn in the
ignition could cause damage to the switch or
break the key. Use the correct key, make sure it is
all the way in, and turn it only with your hand. If the
key cannot be turned by hand, see your
dealer/retailer.
A (LOCK/OFF):This position locks the ignition. It also
locks the transmission. This is the only position in
which the ignition key can be inserted or removed.
2-21

The steering can bind with the wheels turned off center.
If this happens, move the steering wheel from left to
right while turning the key to ACC/ACCESSORY. If this
doesn’t work, then the vehicle needs service.
B (ACC/ACCESSORY):This is the position in which
you can operate the radio and windshield wipers
while the engine is off. To use ACC/ACCESSORY, turn
the key clockwise.
C (ON/RUN):This position can be used to operate the
electrical accessories and to display some instrument
panel cluster warning and indicator lights. The
switch stays in this position when the engine is running.
If you leave the key in the ACC/ACCESSORY or
ON/RUN position with the engine off, the battery could
be drained. You may not be able to start the vehicle
if the battery is allowed to drain for an extended period
of time.D (START):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving.
A warning chime will sound and the Driver Information
Center (DIC) will display DRIVER’S DOOR AJAR
when the driver door is opened, the ignition is in
ACC/ACCESSORY or LOCK/OFF and the key is in the
ignition. SeeDIC Warnings and Messages on
page 3-56for more information.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
