belt BUICK LUCERNE 2007 Service Manual

5. 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.6. If your child restraint manufacturer
recommends using a top tether, attach and
tighten the top tether to the top tether anchor.
Refer to the instructions that came with the
child restraint and seeLower Anchors
and Tethers for Children (LATCH) on page 55.
7. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, if the top tether is
attached to the top tether anchor, disconnect
it. 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.
64

If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children
(LATCH) on page 55.
There is no top tether anchor at the right front
seating position. Do not secure a child seat in this
position if a national or local law requires that
the top tether be anchored or if the instructions
that come with the child restraint say that the top
tether must be anchored. SeeLower Anchors
and Tethers for Children (LATCH) on page 55if
the child restraint has a top tether.You will be using the lap-shoulder belt to secure
the child restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s
frontal airbag. SeePassenger Sensing
System on page 81. We recommend that
rear-facing child restraints be secured in a rear
seat, even if the airbag is off. If your child
restraint is forward-facing, move the seat as
far back as it will go before securing the
child restraint in this seat. SeeManual
Passenger Seat on page 9orPower Seats
on page 9.
When the passenger sensing system has
turned off the right front passenger’s frontal
airbag and seat-mounted side impact airbag,
the off indicator on the passenger airbag status
indicator should light and stay lit when you
turn the ignition to RUN or START. See
Passenger Airbag Status Indicator
on page 198.

2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and
shoulder portions of the vehicle’s safety belt
through or around the restraint. The child
restraint instructions will show you how.
4. Buckle the belt. Make sure the release button
is positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.5. Pull the rest of the shoulder belt all the way
out of the retractor to set the lock.
68

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
overhead console 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 six airbags:
A frontal airbag for the driver and another
frontal airbag for the right front passenger.
A seat-mounted side impact airbag for the
driver and another for the right front
passenger.
A roof-mounted side impact airbag for the
driver and passenger directly behind the driver.
A roof-mounted side impact airbag for the right
front passenger and the person seated directly
behind that passenger.
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 inating bag, all
airbags must inate very quickly to do their job.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 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. All airbags are designed
to work with safety belts but do not
replace them.
CAUTION: (Continued)
70

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.
Seat-mounted side impact airbags and
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.
71

{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 43orInfants and Young
Children on page 46.
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 197for more information.
Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.
72

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.
Your vehicle has a “dual stage” driver airbag,
which adjusts the restraint according to crash
severity using electronic frontal sensor(s) which
help the sensing system distinguish between
a moderate frontal impact and a more severe
frontal impact. The “dual stage” driver airbag
inates to a level less than full deployment for
moderate frontal impacts and to a full deployment
for more severe frontal impacts.Your vehicle also has a “dual depth” passenger
airbag that adjusts the restraint according to crash
severity, seat location, and safety belt status
using electronic frontal sensor(s) and other special
sensors which enable the sensing system to
monitor the status of the front passenger safety
belt and the position of the front passenger
seat. The passenger airbag inates to a reduced
depth when the passenger seat is in a forward
position. For more rearward front seating positions,
the passenger airbag may inate to an increased
depth (a full deployment), based on safety
belt status and the crash severity measured early
in the event. (Always wear your safety belt,
even with frontal airbags.)
76

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 17 to 22 mph
(27 to 35 km/h) if the other sensors do not
over-ride this. 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 has sensors which enable the
sensing system to monitor the position of the right
front passenger’s seat, whether the occupant is
buckled or unbuckled. The passenger seat position
sensor and passenger safety belt buckle switch
provide information which is used to determine if
the airbags should deploy at a reduced level or full
deployment.
77

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.
Airbags supplement 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.
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 vehicles with side
impact airbags.
What Will You See After an Airbag
Inates?
After frontal airbags and seat-mounted side impact
airbags inate, they quickly deate, so quickly
that some people may not even realize an airbag
inated. Roof-mounted side impact airbags
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 bag, the side of the
seatback closest to the door for the seat-mounted
side impact airbags, and the area along the
ceiling of your vehicle near the side windows for
roof-mounted side impact airbags — 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.
