BUICK LACROSSE 2006 Repair Manual

6. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the lap
portion of the belt and feed the shoulder belt back
into the retractor. If you are using a forward-facing
child restraint, you may nd it helpful to use your
knee to push down on the child restraint as you
tighten the belt. You should not be able to pull
more of the belt from the retractor once the lock
has been set.
7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If the airbag is off, the off indicator on the instrument
panel will be lit and stay lit when the key is turned
to RUN or START.If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint.
If after reinstalling the child restraint and restarting the
vehicle, the on indicator is still lit, check to make sure that
the vehicle’s seatback is not pressing the child restraint
into the seat cushion. If this happens, slightly recline
the vehicle’s seatback and adjust the seat cushion if
possible. Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens, adjust
the head restraint.
If the on indicator is still lit, secure the child in the child
restraint in a rear seat position in the vehicle and
check with your dealer.
To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for
an adult or larger child passenger.

Airbag System
Your vehicle has a frontal airbag for the driver and a
frontal airbag for the right front passenger. Your vehicle
may also have roof-mounted side impact airbags.
Roof-mounted side impact airbags are available for the
driver and the passenger seated directly behind the
driver and for the right front passenger and the
passenger seated directly behind that passenger.
If your vehicle has roof-mounted side impact airbags,
the word AIRBAG will appear on the airbag covering on
the ceiling near the side windows.
Frontal airbags are designed to help reduce the risk
of injury from the force of an inating frontal airbag. But
these airbags must inate very quickly to do their job
and comply with federal regulations.Here are the most important things to know about the
airbag system:
{CAUTION:
You can be severely injured or killed in a crash
if you are not wearing your safety belt — even
if you have airbags. Wearing your safety
beltduring 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. All airbags are
designed to work with safety belts but do not
replace them.
CAUTION: (Continued)
1-56

CAUTION: (Continued)
Frontal airbags for the driver and right front
passenger are designed to deploy in moderate
to severe frontal and near frontal crashes. They
are not designed to inate in rollover, rear
crashes, or in many side crashes. And, for some
unrestrained occupants, frontal airbags may
provide less protection in frontal crashes than
more forceful airbags have provided in the past.
Roof-mounted side impact airbags are designed
to inate in moderate to severe crashes where
something hits the side of your vehicle. They
are not designed to inate in frontal, in rollover
or in rear crashes. Everyone in your vehicle
should wear a safety belt properly — whether
or not there is an airbag for that person.
{CAUTION:
Both frontal and side impact airbags inate
with great force, faster than the blink of an
eye. If you are too close to an inating airbag,
as you would be if you were leaning forward,
it could seriously injure you. Safety belts help
keep you in position for airbag ination before
and during a crash. Always wear your safety
belt even with frontal 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.
1-57

{CAUTION:
Anyone who is up against, or very close to,
any airbag when it inates can be seriously
injured or killed. Airbags plus lap-shoulder
belts offer the best protection for adults, 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 your vehicle. To read how,
seeOlder Children on page 1-30orInfants and
Young Children on page 1-33.There is an airbag
readiness light on the
instrument panel cluster,
which shows the airbag
symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAirbag Readiness Light on page 3-34
for more information.
1-58

Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.The right front passenger’s frontal airbag is in the
instrument panel on the passenger’s side.
1-59

If your vehicle has a roof-mounted side impact airbag
for the driver and the person seated directly behind the
driver, it is located in the ceiling above the side
windows.If your vehicle has a roof-mounted side impact airbag
for the right front passenger and the person directly
behind that passenger, it is located in the ceiling above
the side windows.
1-60

{CAUTION:
If something is between an occupant and an
airbag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating 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. And, if your vehicle has
roof-mounted side impact airbags, never
secure anything to the roof of your vehicle
by routing the rope or tiedown through any
door or window opening. If you do, the path
of an inating side impact airbag will be
blocked. The path of an inating airbag
must be kept clear.
When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal or
near-frontal crashes. But they are designed to inate only
if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account a
variety of desired deployment and non-deployment
events and are used to predict how severe a crash is
likely to be in time for the airbags to inate and help
restrain the occupants. Whether your 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.
In addition, your vehicle has “dual-stage” frontal airbags,
which adjust the restraint according to crash severity.
Your vehicle has electronic frontal sensors which help the
sensing system distinguish between a moderate frontal
impact and a more severe frontal impact. For moderate
frontal impacts, these airbags inate at a level less than
full deployment. For more severe frontal impacts, full
deployment occurs. If the front of your vehicle goes
straight into a wall that does not move or deform, the
threshold level for the reduced deployment is about
12 to 16 mph (19 to 26 km/h), and the threshold level
for a full deployment is about 18 to 22 mph
(29 to 35.5 km/h).
1-61

The threshold level can vary, however, with specic
vehicle design, so that it can be somewhat above or
below this range.
Frontal airbags may inate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbags
could inate at a different crash speed than if the
vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate at a different crash speed than
if the vehicle hits an object that does not deform.
If the vehicle hits a narrow object (like a pole) the
airbags could inate at a different crash speed
than if the vehicle hits a wide object (like a wall).
If the vehicle goes into an object at an angle the
airbags could inate at a different crash speed
than if the vehicle goes straight into the object.
Frontal airbags (driver and right front passenger) are
not intended to inate during vehicle rollovers, rear
impacts, or in many side impacts.Your vehicle may or may not have roof-mounted side
impact airbags. SeeAirbag System on page 1-56.
Roof-mounted side impact airbags are intended to inate
in moderate to severe side crashes. A roof-mounted
side impact airbag will inate if the crash severity
is above the system’s designed threshold level. The
threshold level can vary with specic vehicle design.
Roof-mounted side impact airbags are not intended to
inate in frontal or near-frontal impacts, rollovers or
rear impacts. A roof-mounted side impact airbag
is intended to deploy on the side of the vehicle that is
struck.
In any particular crash, no one can say whether an
airbag should have inated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, ination is determined by
what the vehicle hits, the angle of the impact, and how
quickly the vehicle slows down. For roof-mounted
side impact airbags, ination is determined by the
location and severity of the impact.
1-62

What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. The sensing
system triggers a release of gas from the inator, which
inates the airbag. The inator, airbag, and related
hardware are all part of the airbag modules inside the
steering wheel and in the instrument panel in front of the
right front passenger. For vehicles with roof-mounted side
impact airbags, there are also airbag modules in the
ceiling of the vehicle, near the side windows.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The airbag supplements the protection
provided by safety belts. Airbags distribute the force of
the impact more evenly over the occupant’s upper
body, stopping the occupant more gradually. But the
frontal airbags would not help you in many types
of collisions, including rollovers, rear impacts, and many
side impacts, primarily because an occupant’s motion
is not toward the airbag. Side impact airbags would not
help you in many types of collisions, including many
frontal or near frontal collisions, rollovers, and rear
impacts, primarily because an occupant’s motion is
not toward those airbags. Airbags should never
be regarded as anything more than a supplement to
safety belts, and then only in moderate to severe frontal
or near-frontal collisions for the driver’s and right front
passenger’s frontal airbags, and only in moderate
to severe side collisions for side impact airbags.
1-63

What Will You See After an
Airbag Inates?
After a frontal airbag inates, it quickly deates, so
quickly that some people may not even realize
the airbag inated. Roof-mounted side impact airbags
deate more slowly and may still be at least partially
inated minutes after the vehicle comes to rest. Some
components of the airbag module — the steering wheel
hub for the driver’s airbag, the instrument panel for
the right front passenger’s airbag, or the ceiling of your
vehicle near the side windows — may be hot for a
short time. The parts of the airbag that come into contact
with you may be warm, but not too hot to touch.
There will be some smoke and dust coming from the
vents in the deated airbags. Airbag ination does
not prevent the driver from seeing out of the windshield
or being able to steer the vehicle, nor does it stop
people from leaving the vehicle.
{CAUTION:
When an airbag inates, there is 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 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
inates, 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.
