warning BUICK LUCERNE 2010 Service Manual

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 4‑34. 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.
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 4‑33
for more information, including important safety
information.

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 Your
Airbag-Equipped Vehicle
on page 2‑73for 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 8‑17.
{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.

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 4‑33.

Keys
{WARNING:
Leaving children in a vehicle with the ignition key
is dangerous for many reasons, children or others
could be badly injured or even killed. They could
operate the power windows or other controls or
even make the vehicle move. The windows will
function with the keys in the ignition and children
could be seriously injured or killed if caught in the
path of a closing window. Do not leave the keys in
a vehicle with children.
The key can be used for the ignition, the driver's door,
and the glovebox lock.
The key has a bar-coded key tag that the dealer or
qualified locksmith can use to make new keys. Store
this information in a safe place, not in your vehicle.
See your dealer if a replacement key or additional key
is needed.
Notice:If you ever lock your keys in the vehicle,
you may have to damage the vehicle to get in. Be
sure you have spare keys.
3-3

Programming Transmitters to the
Vehicle
Only RKE transmitters programmed to the vehicle will
work. If a transmitter is lost or stolen, a replacement can
be purchased and programmed through your dealer.
When the replacement transmitter is programmed to
the vehicle, all remaining transmitters must also be
programmed. Any lost or stolen transmitters no longer
work once the new transmitter is programmed. Each
vehicle can have up to eight transmitters programmed
to it. See“Remote Key” underDIC Operation and
Displays on page 4‑47.
Battery Replacement
Replace the battery if the REPLACE BATTERY IN
REMOTE KEY message appears in the DIC. See
“REPLACE BATTERY IN REMOTE KEY” underDIC
Warnings and Messages
on page 4‑55for additional
information.
Notice: When replacing the battery, do not touch
any of the circuitry on the transmitter. Static from
your body could damage the transmitter.
To replace the battery:
1. Separate the transmitter with a flat, thin object, such as a flat head screwdriver.
.Carefully insert the tool into the notch located
along the parting line of the transmitter. Do
not insert the tool too far. Stop as soon as
resistance is felt.
.Twist the tool until the transmitter is separated.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery, positive side facing down. Replace with a CR2032 or equivalent battery.
4. Snap the transmitter back together.
3-6

To manually shut off a remote start:
.Aim the RKE transmitter at the vehicle and press
the remote start button until the parking lamps
turn off.
.Turn on the hazard warning flashers.
.Turn the ignition switch on and then off.
The vehicle can be started remotely two separate times
between driving sequences. The engine will run for
10 minutes after each remote start.
Or, you can extend the engine run time by another
10 minutes within the first 10 minute remote start time
frame, and before the engine stops.
For example, if the lock button and then the remote start
buttons are pressed again after the vehicle has been
running for five minutes, 10 minutes are added, allowing
the engine to run for 15 minutes.
The additional 10 minutes are considered a second
remote vehicle start. Once two remote starts, or a single remote start with
one time extension have been done, the vehicle must
be started with the key.
After the key is removed from the ignition, another
remote start can be performed.
The vehicle cannot be started remotely if the key is in
the ignition, the hood is not closed, or if there is an
emission control system malfunction.
Remote Start Ready
If your vehicle does not have the remote vehicle start
feature, it may have the remote start ready feature. This
feature allows your dealer to add the manufacturer's
remote vehicle start feature.
See your dealer if you would like to add the
manufacturer's remote vehicle start feature to your
vehicle.

Doors and Locks
Door Locks
{WARNING:
Unlocked doors can be dangerous.
.Passengers, especially children, can easily
open the doors and fall out of a moving
vehicle. When a door is locked, the handle will
not open it. The chance of being thrown out of
the vehicle in a crash is increased if the doors
are not locked. So, all passengers should
wear safety belts properly and the doors
should be locked whenever the vehicle is
driven.(Continued)
WARNING: (Continued)
.Young children who get into unlocked vehicles
may be unable to get out. A child can be
overcome by extreme heat and can suffer
permanent injuries or even death from heat
stroke. Always lock the vehicle whenever
leaving it.
.Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
From the outside, use either the key or the Remote
Keyless Entry (RKE) transmitter.
From the inside, use the power door lock switches or
manual lock knobs. The manual lock knobs are located
at the top of the door panel near the window.
Push the manual lock knob down to lock the door.
To unlock the door, pull up on the knob.
3-9

Lockout Protection
If the key is in the ignition and the power door lock
switch is used to lock the doors, all doors will lock
and then the driver door will unlock. It is always
recommended that the ignition key is removed from
the vehicle when locking the doors.
The lockout protection feature can be overridden by
holding the power door lock switch for three seconds or
longer.
Trunk
{WARNING:
Exhaust gases can enter the vehicle if it is driven
with the liftgate, trunk/hatch open, or with any
objects that pass through the seal between the
body and the trunk/hatch or liftgate. Engine
exhaust contains Carbon Monoxide (CO) which
cannot be seen or smelled. It can cause
unconsciousness and even death.(Continued)
WARNING: (Continued)
If the vehicle must be driven with the liftgate,
or trunk/hatch open:
.Close all of the windows.
.Fully open the air outlets on or under the
instrument panel.
.Adjust the Climate Control system to a setting
that brings in only outside air and set the fan
speed to the highest setting. See Climate
Control System in the Index.
.If the vehicle is equipped with a power liftgate,
disable the power liftgate function.
For more information about carbon monoxide, see
Engine Exhaust on page 3‑31.

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. To close the door,
raise it and push it until it latches.
Windows
{WARNING:
Leaving children, helpless adults, or pets in a
vehicle with the windows closed is dangerous.
They can be overcome by the extreme heat and
suffer permanent injuries or even death from heat
stroke. Never leave a child, a helpless adult, or a
pet alone in a vehicle, especially with the windows
closed in warm or hot weather.
