Safety Belt Care
Keep belts clean and dry.
{WARNING
Do not bleach or dye safety belts.
It may severely weaken them.
In a crash, they might not be able
to provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.
Replacing Safety Belt
System Parts After a
Crash
{WARNING
A crash can damage the safety
belt system in the vehicle.
A damaged safety belt system
may not properly protect the
person using it, resulting in
serious injury or even death in
a crash. To help make sure the
safety belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon
as possible.After a minor crash, replacement of
safety belts may not be necessary.
But the safety belt assemblies that
were used during any crash may
have been stressed or damaged.
See your dealer to have the safety
belt assemblies inspected or
replaced.
New parts and repairs may be
necessary even if the safety belt
system was not being used at the
time of the crash.
Have the safety belt pretensioners
checked if the vehicle has been in a
crash, or if the airbag readiness light
stays on after you start the vehicle
or while you are driving. See
Airbag
Readiness Light on page 5‑14.

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.

If the vehicle has second row
seat‐mounted side impact airbags,
they are in the sides of the rear
seatback closest to the door.
{WARNING
If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into (Continued)
WARNING (Continued)
that person causing severe
injury or even death. The path
of an inflating airbag must be
kept clear. Do not put anything
between an occupant and an
airbag, and do not attach or put
anything on the steering wheel
hub or on or near any other
airbag covering.
Do not use seat accessories
that block the inflation path of a
seat-mounted side impact airbag.
Never secure anything to the roof
of a vehicle with roof-rail airbags
by routing a rope or tie down
through any door or window
opening. If you do, the path
of an inflating roof-rail airbag
will be blocked.
When Should an Airbag
Inflate?
Frontal airbags are designed
to inflate in moderate to severe
frontal or near frontal crashes to
help reduce the potential for severe
injuries mainly to the driver's or right
front passenger's head and chest.
However, they are only designed
to inflate if the impact exceeds
a predetermined deployment
threshold. Deployment thresholds
are used to predict how severe a
crash is likely to be in time for the
airbags to inflate and help restrain
the occupants.
Whether the frontal airbags will
or should deploy is not based on
how fast your vehicle is traveling.
It depends largely on what you hit,
the direction of the impact, and how
quickly your vehicle slows down.

Black plate (35,1)Buick LaCrosse Owner Manual - 2011
Seats and Restraints 3-35
But airbags would not help in
many types of collisions, primarily
because the occupant's motion
is not toward those airbags.
SeeWhen Should an Airbag
Inflate? on page 3‑32 for more
information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See After
an Airbag Inflates?
After the frontal airbags and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may
not even realize an airbag inflated.
Roof-rail airbags may still be at least
partially inflated for some time after
they deploy. Some components of
the airbag module may be hot for several minutes. For location of the
airbag modules, see
What Makes
an Airbag Inflate? on page 3‑34.
The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There may
be some smoke and dust coming
from the vents in the deflated
airbags. Airbag inflation does not
prevent the driver from seeing out
of the windshield or being able to
steer the vehicle, nor does it prevent
people from leaving the vehicle.{WARNING
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.
To avoid this, everyone in the
(Continued)
WARNING (Continued)
vehicle should get out as soon
as it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers, and shut off the
fuel system after the airbags inflate.
You can lock the doors, turn off the
interior lamps and hazard warning
flashers by using the controls for
those features.

{WARNING
A crash severe enough to
inflate the airbags may have
also damaged important functions
in the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.In many crashes severe enough
to inflate the airbag, windshields
are broken by vehicle deformation.
Additional windshield breakage
may also occur from the right front
passenger airbag.
.Airbags are designed to inflate
only once. After an airbag
inflates, you will need some
new parts for the 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 the need
to replace other parts.
.The vehicle has a crash
sensing and diagnostic module
which records information after
a crash. See
Vehicle Data
Recording and Privacy on
page 13‑18 andEvent Data
Recorders on page 13‑18.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.

A label on the sun visor says,
“Never put a rear-facing child seat
in the front.”This is because the risk
to the rear-facing child is so great,
if the airbag deploys.
{WARNING
A child in a rear-facing child
restraint can be seriously
injured or killed if the right
front passenger airbag inflates.
This is because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the right front
passenger airbag inflates and the
passenger seat is in a forward
position.
(Continued)
WARNING (Continued)
Even if the passenger sensing
system has turned off the right
front passenger frontal airbag,
no system is fail-safe. No one
can guarantee that an airbag will
not deploy under some unusual
circumstance, even though the
airbag is turned off.
Secure rear-facing child
restraints in a rear seat, even if
the airbag is off. If you secure a
forward-facing child restraint in
the right front seat, always move
the front passenger seat as far
back as it will go. It is better to
secure the child restraint in a
rear seat. The passenger sensing system is
designed to turn off the right front
passenger frontal airbag if:.The right front passenger seat is
unoccupied.
.The system determines that an
infant is present in a rear-facing
infant seat.
.The system determines that a
small child is present in a child
restraint.
.The system determines that
a small child is present in a
booster seat.
.A right front passenger takes
his/her weight off of the seat for
a period of time.
.The right front passenger seat is
occupied by a smaller person,
such as a child who has
outgrown child restraints.
.Or, if there is a critical problem
with the airbag system or the
passenger sensing system.

When the passenger sensing
system has turned off the right
front passenger frontal airbag,
the off indicator will light and stay
lit to remind you that the airbags
are off. SeePassenger Airbag
Status Indicator on page 5‑15.
The passenger sensing system is
designed to turn on (may inflate)
the right front passenger frontal
airbag anytime the system senses
that a person of adult size is sitting
properly in the right front passenger
seat. When the passenger sensing
system has allowed the airbag to be
enabled, the on indicator will light
and stay lit to remind you that the
airbag is active.
For some children who have
outgrown child restraints and for
very small adults, the passenger
sensing system may or may not turn off the right front passenger
frontal airbag, depending upon
the person's seating posture
and body build. Everyone in the
vehicle who has outgrown child
restraints should wear a safety
belt properly
—whether or not
there is an airbag for that person.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. See Airbag Readiness
Light on page 5‑14 for more
information, including important
safety information.
If the On Indicator is Lit for a
Child Restraint
If a child restraint has been installed
and the on indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
4. Reinstall the child restraint following the directions
provided by the child restraint
manufacturer and refer to
Securing Child Restraints
(Rear Seat) on page 3‑61 or
Securing Child Restraints (Front
Passenger Seat) on page 3‑63.

Additional Factors Affecting
System Operation
Safety belts help keep the
passenger in position on the
seat during vehicle maneuvers
and braking, which helps the
passenger sensing system
maintain the passenger airbag
status. See“Safety Belts” and
“Child Restraints” in the Index for
additional information about the
importance of proper restraint use.
A thick layer of additional material,
such as a blanket or cushion,
or aftermarket equipment such
as seat covers, seat heaters, and
seat massagers can affect how
well the passenger sensing system
operates. We recommend that
you not use seat covers or other
aftermarket equipment except when
approved by GM for your specific
vehicle. See Adding Equipment to
the Airbag-Equipped Vehicle on
page 3‑42 for more information
about modifications that can
affect how the system operates.
{WARNING
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are
parts of the airbag system in
several places around the vehicle.
Your dealer and the service manual
have information about servicing
the vehicle and the airbag system.
To purchase a service manual,
see Service Publications Ordering
Information on page 13‑15.
{WARNING
For up to 10 seconds after the
ignition is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
