2005 BUICK LACROSSE power window

Your vehicle has a feature that will automatically unlock
the doors, turn the interior lamps on, and ash the
hazard warning ashers when the airbag inates,
if battery power is available. You can lock the doors and
turn the interior lamps and hazard warning ashers
off by using the controls for those features.
In many crashes severe enough to inate an airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger airbag.
Airbags are designed to inate only once. After an
airbag inates, you will need some new parts for
your airbag system. If you do not get them,
the airbag system will not be there to help protect
you in another crash. A new system will include
airbag modules and possibly other parts. The
service manual for your vehicle covers other parts
that need to be replaced.
Your vehicle is equipped with a crash sensing and
diagnostic module which records information after
a crash. SeeVehicle Data Collection and Event
Data Recorders on page 7-9.
Let only qualied technicians work on your airbag
system. Improper service can mean that your
airbag system will not work properly. See your GM
dealer for service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, or the side
impact airbag covering on the ceiling near the side
windows, the airbag may not work properly. You
may have to replace the airbag module in the
steering wheel, both the airbag module and the
instrument panel for the right front passenger’s
airbag, or side impact airbag module and ceiling
covering for roof-mounted side impact airbags. Do
not open or break the airbag coverings.

Section 2 Features and Controls
2-1

Keys
{CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. They
could operate the power windows or other
controls or even make the vehicle move. The
children or others could be badly injured or
even killed. Do not leave the keys in a vehicle
with children.
2-2

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.
2-13

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.
2-16

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

Backglass Antenna
The AM-FM antenna is integrated with the rear window
defogger, located in the rear window. Be sure that the
inside surface of the rear window is not scratched and
that the lines on the glass are not damaged. If the inside
surface is damaged, it could interfere with radio
reception. Also, for proper radio reception, the antenna
connector at the top-center of the rear window needs to
be properly attached to the post on the glass.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear window
antenna and/or the rear window defogger. Repairs
would not be covered by your warranty. Do not clear
the inside rear window with sharp objects.
Notice:Do not apply aftermarket glass tinting with
metallic lm. The metallic lm in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to your
backglass antenna due to metallic tinting materials
will not be covered by your warranty.
Because this antenna is built into your rear window,
there is a reduced risk of damage caused by car washes
and vandals.If you choose to add a cellular telephone to your
vehicle, and the antenna needs to be attached to the
glass, be sure that you do not damage the grid lines for
the AM-FM antenna. There is enough space between
the lines to attach a cellular telephone antenna
without interfering with radio reception.
Do not apply aftermarket glass tinting to the back glass.
The metallic lm in some tinting materials will interfere
with or distort the incoming radio reception. Care
must be taken when cleaning the rear window because
it breaks in the resistive material heating element
and will adversely affect radio and defogger
performance. See your dealer for details.
Chime Level Adjustment
The radio is the vehicle’s chime producer. To change
the volume level, press and hold pushbutton 6 with
the ignition on and the radio power off. The chime
volume level will change from the normal level to loud,
and LOUD will appear on the radio display. To
change back to the default or normal setting, press and
hold pushbutton 6 again. The chime level will change
from the loud level to normal, and NORMAL will appear
on the radio display. Removing the radio and not
replacing it with a factory radio or chime will disable
vehicle chimes.
