Passenger Sensing System
The vehicle has a passenger sensing system for the
right front passenger position. The passenger airbag
status indicator will be visible on the overhead console
when the vehicle is started.
United StatesCanada
The words ON and OFF, or the symbol for on and off,
are visible during the system check. If you are using
remote start, if equipped, to start the vehicle from a
distance, you may not see the system check. When
the system check is complete, either the word ON or
OFF, or the symbol for on or off, will be visible. See
Passenger Airbag Status Indicator on page 4‑31. The passenger sensing system turns off the right front
passenger frontal airbag and seat-mounted side impact
airbag under certain conditions. The driver airbags and
the roof-rail airbags are not affected by the passenger
sensing system.
The passenger sensing system works with sensors
that are part of the right front passenger seat. The
sensors are designed to detect the presence of a
properly-seated occupant and determine if the right
front passenger frontal airbag and seat‐mounted side
impact airbag should be enabled (may inflate) or not.
According to accident statistics, children are safer when
properly secured in a rear seat in the correct child
restraint for their weight and size.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing child
restraint; a child riding in a forward-facing child seat; an
older child riding in a booster seat; and children, who
are large enough, using safety belts.
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.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag and
seat-mounted side impact airbag (if equipped),
no system is fail-safe. No one can guarantee that
an airbag will not deploy under some unusual
circumstance, even though the airbag(s) are off.
Secure rear-facing child restraints in a rear seat,
even if the airbag(s) are 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 airbag and seat‐mounted side
impact 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 and seat‐mounted
side impact airbag, the off indicator will light and stay lit
to remind you that the airbags are off. See Passenger
Airbag Status Indicator on page 4‑31.
The passenger sensing system is designed to turn on
(may inflate) the right front passenger frontal airbag and
seat‐mounted side impact airbag anytime the system
senses that a person of adult size is sitting properly in
the right front passenger seat.
2-65
Page 98 of 450

Black plate (66,1)Buick Lucerne Owner Manual - 2011
When the passenger sensing system has allowed the
airbags to be enabled, the on indicator will light and
stay lit to remind you that the airbags are 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 and seat-mounted side impact 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 4‑30
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 a Child Restraint in the Right
Front Seat Position on page 2‑52.
5. If, after reinstalling the child restraint and restarting the vehicle, the on indicator is still lit, turn the
vehicle off. Then slightly recline the vehicle
seatback and adjust the seat cushion, if adjustable,
to make sure that the vehicle seatback is not
pushing the child restraint into the seat cushion.
Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint. See Head Restraints
on
page 2‑2.

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. SeeAdding Equipment to
Your Airbag-Equipped Vehicle
on page 2‑69for 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 Your 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 8‑14.
{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.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q: Is there anything I might add to or change aboutthe vehicle that could keep the airbags from
working properly?
A: Yes. If you add things that change your vehicle's
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts of
the front seats, safety belts, the airbag sensing and
diagnostic module, steering wheel, instrument panel,
roof-rail airbag modules, ceiling headliner or pillar
garnish trim, overhead console, front sensors, side
impact sensors, or airbag wiring can affect the
operation of the airbag system.
In addition, your vehicle has a passenger sensing
system for the right front passenger's position, which
includes sensors that are part of the passenger's
seat. The passenger sensing system may not
operate properly if the original seat trim is replaced
with non-GM covers, upholstery or trim, or with GM
covers, upholstery or trim designed for a different
vehicle. Any object, such as an aftermarket seat
heater or a comfort enhancing pad or device, installed under or on top of the seat fabric, could
also interfere with the operation of the passenger
sensing system. This could either prevent proper
deployment of the passenger airbag(s) or prevent
the passenger sensing system from properly turning
off the passenger airbag(s). See
Passenger Sensing
System on page 2‑64.
If you have any questions about this, you should
contact Customer Assistance before you modify
your vehicle. The phone numbers and addresses
for Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this manual.
See Customer Satisfaction Procedure on page 8‑2.
Q: Because I have a disability, I have to get my vehicle modified. How can I find out whether this
will affect my airbag system?
A: If you have questions, call Customer Assistance.
The phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual. See
Customer Satisfaction Procedure on page 8‑2.
In addition, your dealer and the service manual have
information about the location of the airbag sensors,
sensing and diagnostic module and airbag wiring.

Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, check that the safety belt reminder light,
safety belts, buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or damaged safety belt system
parts that might keep a safety belt system from doing its
job. See your dealer to have it repaired. Torn or frayed
safety belts may not protect you in a crash. They can rip
apart under impact forces. If a belt is torn or frayed, get
a new one right away.
Make sure the safety belt reminder light is working.
SeeSafety Belt Reminders
on page 4‑29for more
information.
Keep safety belts clean and dry. See Care of Safety
Belts
on page 6‑101.
Airbags
The airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. See Airbag Readiness Light
on page 4‑30for more information.
Notice: If an airbag covering is damaged, opened,
or broken, the airbag may not work properly. Do not
open or break the airbag coverings. If there are any
opened or broken airbag covers, have the airbag
covering and/or airbag module replaced. For the
location of the airbag modules, see What Makes an
Airbag Inflate?
on page 2‑61. See your dealer for
service.

Replacing Restraint System Parts
After a Crash
{WARNING:
A crash can damage the restraint systems in your
vehicle. A damaged restraint system may not
properly protect the person using it, resulting in
serious injury or even death in a crash. To help
make sure your restraint systems are working
properly after a crash, have them inspected and
any necessary replacements made as soon as
possible.
If the vehicle has been in a crash, do you need new
safety belts or LATCH system (if equipped) parts?
After a very minor crash, nothing may 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. If the vehicle has the LATCH system and it was being
used during a crash, you may need new LATCH system
parts.
New parts and repairs may be necessary even if the
safety belt or LATCH system (if equipped), was not
being used at the time of the crash.
If an airbag inflates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
Have the safety belt pretensioners checked if the
vehicle has been in a crash, if the airbag readiness light
stays on after the vehicle is started, or while you are
driving. See
Airbag Readiness Light
on page 4‑30.
