2007 BUICK LUCERNE ECU

Let only qualied technicians work on the
airbag systems. Improper service can
mean that an airbag system will not work
properly. See your dealer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system.
The passenger airbag status indicator on the
overhead console will be visible when you turn
your ignition key to RUN or START.
The words ON and OFF or the symbol for on and
off, will be visible during the system check.
When the system check is complete, either the
word ON or the word OFF, or the symbol for on or
the symbol for off will be visible. SeePassenger
Airbag Status Indicator on page 198.The passenger sensing system will turn off the
right front passenger’s frontal airbag and
seat-mounted side impact airbag under certain
conditions. The driver’s airbags are not part of the
passenger sensing system.
The passenger sensing system works with sensors
that are part of the right front passenger’s seat and
safety belt. The sensors are designed to detect the
presence of a properly-seated occupant and
determine if the right front passenger’s frontal
airbag and seat-mounted side impact airbag should
be enabled (may inate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. We recommend that child restraints be
secured in a rear seat, including an infant riding in
a rear-facing infant seat, a child riding in a
forward-facing child seat and an older child riding
in a booster seat.

Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your 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.
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag.
CAUTION: (Continued)
CAUTION: (Continued)
Even though the passenger sensing
system is designed to turn off the right
front passenger’s frontal and
seat-mounted side impact airbag if the
system detects a rear-facing child
restraint, no system is fail-safe, and no
one can guarantee that an airbag will not
deploy under some unusual circumstance,
even though it is turned off. We
recommend that rear-facing child
restraints be secured in the rear seat,
even if the airbags are off.
If you need to 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.
82

The passenger sensing system is designed to turn
off the right front passenger’s frontal 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 forward-facing 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’s frontal airbag
and seat-mounted side impact airbag, the off
indicator will light and stay lit to remind you that
the airbags are off.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 following the child restraint
manufacturer’s directions and refer toSecuring a
Child Restraint in the Right Front Seat Position
on page 65.
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.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the 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.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors. 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. SeeCustomer
Satisfaction Procedure on page 460.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel,
instrument panel, ceiling headliner, ceiling and
pillar garnish trim, roof-mounted airbag
modules, or airbag wiring can affect the
operation of the airbag system. 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.

on page 460.

Personal Choice Programming
The delayed locking feature can be turned on or
off, using the Driver Information Center (DIC)
to program this feature. See “DELAY DOOR
LOCK” underDIC Vehicle Customization on
page 231.
Programmable Automatic
Door Locks
Your vehicle is programmed so that, when the
doors are closed, the ignition is on, and the shift
lever is moved out of PARK (P), all the doors will
lock. The doors will unlock every time you stop the
vehicle and move the shift lever into PARK (P).
If someone needs to get out while your vehicle is
not in PARK (P), have the person use the manual
lock knob or power door lock switch. When the door
is closed again, it will not lock automatically. Use
the manual lock knob or power door lock switch to
lock the door.
If your vehicle has a Driver Information Center
(DIC), you can choose various lock and unlock
settings. For programming information, see
DIC Vehicle Customization on page 231.

prevent passengers from opening the rear doors
from the inside.
The rear door security locks are located on the
inside edge of each rear door. You must open the
rear doors to access them.

Emergency Trunk Release Handle
Notice:Do not use the emergency trunk
release handle as a tie-down or anchor point
when securing items in the trunk as it could
damage the handle. The emergency trunk
release handle is only intended to aid a person
trapped in a latched trunk, enabling them to
open the trunk from the inside.There is a glow-in-the-dark emergency trunk
release handle located inside the trunk near the
latch. This handle will glow following exposure
to light. Pull the release handle to open the trunk
from the inside.
Rear Seat Pass-Through
Your vehicle has a small door in the rear seat.
This door allows you to access the trunk from
inside the vehicle.
The rear seat armrest must be down for the
pass-through door to open. To release the
pass-through door, move the release lever up with
your ngers. To close the door, raise it and push it
