Windows
{WARNING
Leaving children, helpless
adults, or pets in a vehicle
with the windows closed is
dangerous. They can be
overcome by the extreme heat
and suffer permanent injuries
or even death from heat stroke.
Never leave a child, a helpless
adult, or a pet alone in a vehicle,
especially with the windows
closed in warm or hot weather.
The vehicle aerodynamics are
designed to improve fuel economy
performance. This may result in a
pulsing sound when either rear
window is down and the front
windows are up. To reduce the
sound, open either a front window
or the sunroof (if equipped).

sunroof and remove any obstacles
or loose debris. Wipe the sunroof
seal and roof sealing area using a
clean cloth, mild soap, and water.

Seats and Restraints 3-29
Airbag System
The vehicle has the following
airbags:
.A frontal airbag for the driver.
.A frontal airbag for the right front
passenger.
.A seat-mounted side impact
airbag for the driver.
.A seat-mounted side impact
airbag for the right front
passenger.
.A roof-rail airbag for the driver
and the passenger seated
directly behind the driver.
.A roof-rail airbag for the
right front passenger and
the passenger seated directly
behind the right front passenger.The vehicle may have the following
airbags:
.A seat-mounted side impact
airbag for the rear seat
passenger seated directly
behind the driver.
.A seat-mounted side impact
airbag for the rear seat
passenger seated directly
behind the right front passenger.
All of the airbags in the vehicle will
have the word AIRBAG embossed
in the trim or on an attached label
near the deployment opening.
For frontal airbags, the word
AIRBAG will appear on the middle
part of the steering wheel for the
driver and on the instrument panel
for the right front passenger. With seat-mounted side impact
airbags, the word AIRBAG will
appear on the side of the seatback
closest to the door.
With roof-rail airbags, the word
AIRBAG will appear along the
headliner or trim.
Airbags are designed to supplement
the protection provided by safety
belts. Even though today's airbags
are also designed to help reduce
the risk of injury from the force of an
inflating bag, all airbags must inflate
very quickly to do their job.

Black plate (30,1)Buick LaCrosse Owner Manual - 2011
3-30 Seats and Restraints
Here are the most important things
to know about the airbag system:
{WARNING
You can be severely injured or
killed in a crash if you are not
wearing a safety belt—even if
the vehicle has airbags. Airbags
are designed to work with safety
belts, but do not replace them.
Also, airbags are not designed to
deploy in every crash. In some
crashes safety belts are the only
restraint. See When Should an
Airbag Inflate? on page 3‑32.
Wearing a safety belt during a
crash helps reduce your chance
of hitting things inside the vehicle
or being ejected from it. Airbags
are “supplemental restraints” to
the safety belts. Everyone in the
vehicle should wear a safety belt
properly —whether or not there is
an airbag for that person.
{WARNING
Airbags inflate with great force,
faster than the blink of an eye.
Anyone who is up against, or
very close to, any airbag when it
inflates can be seriously injured
or killed. Do not sit unnecessarily
close to any airbag, as you would
be if you were sitting on the edge
of the seat or leaning forward.
Safety belts help keep you in
position before and during a
crash. Always wear a safety belt,
even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle.
Occupants should not lean on
or sleep against the door or side
windows in seating positions with
seat-mounted side impact airbags
and/or roof-rail airbags.
{WARNING
Children who are up against,
or very close to, any airbag
when it inflates can be seriously
injured or killed. Airbags plus
lap-shoulder belts offer protection
for adults and older children,
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 the vehicle. To read how, see
Older Children on page 3‑44 or
Infants and Young Children on
page 3‑46.
