2010 BUICK LUCERNE wheel

{WARNING:
If something is between an occupant and an
airbag, the airbag might not inflate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inflating 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.
Do not use seat accessories that block the
inflation path of a seat-mounted side impact
airbag.
Never secure anything to the roof of a vehicle with
roof-rail airbags by routing a rope or tie down
through any door or window opening. If you do,
the path of an inflating roof-rail airbag will be
blocked.
When Should an Airbag Inflate?
Frontal airbags are designed to inflate in moderate to
severe frontal or near-frontal crashes to help reduce the
potential for severe injuries mainly to the driver's or right
front passenger's head and chest. However, they are
only designed to inflate if the impact exceeds a
predetermined deployment threshold. Deployment
thresholds are used to predict how severe a crash is
likely to be in time for the airbags to inflate 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.
2-61

What Makes an Airbag Inflate?
In a deployment event, the sensing system sends an
electrical signal triggering a release of gas from the
inflator. Gas from the inflator fills the airbag causing the
bag to break out of the cover and deploy. The inflator,
the airbag, and related hardware are all part of the
airbag module.
Frontal airbag modules are located inside the steering
wheel and instrument panel. For vehicles with
seat-mounted side impact airbags, there are airbag
modules in the side of the front seatbacks closest to the
door. For vehicles with roof-rail airbags, there are airbag
modules in the ceiling of the vehicle, near the side
windows that have occupant seating positions.
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. Frontal airbags distribute the force of the impact
more evenly over the occupant's upper body, stopping
the occupant more gradually. Seat-mounted side impact
and roof-rail airbags distribute the force of the impact
more evenly over the occupant's upper body.
But airbags would not help in many types of collisions,
primarily because the occupant's motion is not toward
those airbags. SeeWhen Should an Airbag Inflate?
on
page 2‑61for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.

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 2‑67.
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.

Ignition Positions
The ignition has four different positions:
In order to shift out of P (Park), ignition must be in
the ON/RUN and the regular brake pedal must be
applied.
Notice:Using a tool to force the key to turn in the
ignition could cause damage to the switch or break
the key. Use the correct key, make sure it is all the
way in, and turn it only with your hand. If the key
cannot be turned by hand, see your dealer.
A (LOCK/OFF): This position locks the ignition. It also
locks the transmission and steering column. This is the
only position in which the ignition key can be inserted or
removed. The steering can bind with the wheels turned off center.
If this happens, move the steering wheel from right to
left while turning the key to ACC/ACCESSORY. If this
doesn't work, then the vehicle needs service.
B (ACC/ACCESSORY):
This position lets the radio
and windshield wipers operate while the engine is off.
To use ACC/ACCESSORY, turn the key clockwise.
C (ON/RUN): This position can be used to operate
electrical accessories and to display some of the
warning and indicator lights. The switch stays in this
position when the engine is running.
If you leave the key in the ACC/ACCESSORY or
ON/RUN position with the engine off, the battery could
be drained. You may not be able to start the vehicle if
the battery is allowed to drain for an extended period
of time.
D (START): This position starts the engine. When the
engine starts, release the key. The ignition switch
returns to ON/RUN for driving.
A warning tone will sound and the Driver Information
Center (DIC) will display DRIVER DOOR OPEN when
the driver door is opened if the ignition is in LOCK/OFF,
ACC/ACCESSORY and the key is in the ignition. See
DIC Warnings and Messages
on page 4‑55for more
information.

Retained Accessory Power (RAP)
The following accessories can be used for up to
10 minutes after the engine is turned off.
.Audio System
.Audio Steering Wheel (if equipped)
.Clock
.Power Windows
.Sunroof (if equipped)
Power to these accessories works up to 10 minutes or
until the driver door is opened.
The instrument panel cluster lights stay on for a few
seconds, then will go out. Once the driver door is
opened, the power shuts off to these accessories. The
vehicle has a feature designed to protect the battery
against drainage. For more information see Inadvertent
Power Battery Saver
on page 4‑16and Electric Power
Management on page 4‑16.
Starting the Engine
Move the shift lever to P (Park) or N (Neutral). The
engine will not start in any other position. To restart
the engine when the vehicle is already moving, use
N (Neutral) only.
Notice: Do not try to shift to P (Park) if the vehicle
is moving. If you do, you could damage the
transmission. Shift to P (Park) only when the
vehicle is stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn the ignition to START. When the engine starts, let
go of the key. The idle speed will slow down
as the engine warms. Do not race the engine
immediately after starting it. Operate the engine
and transmission gently to allow the oil to warm up
and lubricate all moving parts.

Automatic Transmission Operation
The vehicle may have a shift lever located either on the
steering column or on the console between the seats.
P (Park):This position locks the front wheels. It is the
best position to use when you start the engine because
the vehicle cannot move easily.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). See Shifting Into
Park
on page 3‑27. If you are pulling a trailer,
see Towing a Trailer on page 5‑27.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You have to fully
apply the regular brakes before you can shift from
P (Park) while the ignition is in ON/RUN. If you cannot
shift out of P (Park), ease pressure on the shift lever
and push the shift lever all the way into P (Park) as you
maintain brake application. Then move the shift lever
into the gear you want. See Shifting Out of Park
on
page 3‑30.
3-24

R (Reverse):Use this gear to back up.
Notice: Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission, see If
Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on
page 5‑18.
N (Neutral): In this position, the engine does not
connect with the wheels. To restart the engine when
the vehicle is already moving, use N (Neutral) only.
Also, use N (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed. Notice:
Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage the
transmission. The repairs would not be covered by
the vehicle warranty. Be sure the engine is not
running at high speed when shifting the vehicle.
D (Drive): This position is for normal driving. It provides
the best fuel economy. If you need more power for
passing, and you are:
.Going less than about 35 mph (55 km/h), push the
accelerator pedal about halfway down.
.Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transmission will shift down to the next gear
and have more power.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”
under Loss of Control on page 5‑10
3 (Third): This position is also used for normal driving.
It reduces vehicle speed more than D (Drive) without
using the brakes. You might choose 3 (Third) instead of
D (Drive) when driving on hilly, winding roads, when
towing a trailer, so there is less shifting between gears
and when going down a steep hill.
