2006 Buick Lucerne Owner ManualM

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.
Frontal airbags are designed to help reduce the risk of
injury from the force of an inating airbag. But these
airbags must inate very quickly to do their job
and comply with federal regulations.
1-52

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)
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.
1-53

The seat-mounted side impact airbag for the right front
passenger is in the side of the passenger’s seatback
closest to the door.The roof-mounted side impact airbag for the driver and
the person seated directly behind the driver is in the
ceiling above the side windows.
1-57

The roof-mounted side impact airbag for the right front
passenger and the person seated directly behind
that passenger is in the ceiling above the side windows.
{CAUTION:
If something is between an occupant and an
airbag, the airbag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating 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. Never secure anything to the
roof of your vehicle by routing the rope or
tie-down through any door or window opening.
If you do, the path of an inating airbag will be
blocked. Do not let seat covers block the
ination path of a side impact airbag. The path
of an inating airbag must be kept clear.
1-58

What Will You See After an
Airbag Inates?
After the airbags inate, they quickly deate, so quickly
that some people may not even realize the airbags
inated. 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 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 bag that come into contact with you may be warm,
but not too hot to touch. There will be some smoke and
dust coming from the vents in the deated airbags. Airbag
ination does not prevent the driver from seeing out of the
windshield or being able to steer the vehicle, nor does it
stop people from leaving the vehicle.
{CAUTION:
When an airbag inates, there is dust in the air.
This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in the
vehicle should get out as soon as it is safe to do
so. If you have breathing problems but cannot
get out of the vehicle after an airbag inates,
then get fresh air by opening a window or a
door. If you experience breathing problems
following an airbag deployment, you should
seek medical attention.
Your vehicle has a feature that may automatically unlock
the doors and turn the interior lamps on when the airbags
inate (if battery power is available). You can lock the
doors again and turn the interior lamps off by using the
door lock and interior lamp controls. The hazard warning
ashers will also come on when the airbags deploy. If you
want to turn them off, press the hazard warning asher
button twice.

Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired. Keep safety belts clean and
dry. SeeCare of Safety Belts on page 5-86for
more information.
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.Also look for any opened or broken airbag covers, and
have them repaired or replaced. (The airbag system
does not need regular maintenance.)
Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, or the airbag
covering on the driver’s and right front passenger’s
seatback, or the side impact airbag covering on
the ceiling near the side windows, the bag may not
work properly. You may have to replace the
airbag module in the steering wheel, both the airbag
module and the instrument panel for the right
front passenger’s airbag, the airbag module and
seatback for the driver’s and right front passenger’s
seat-mounted side impact airbags, or side impact
airbag module and ceiling covering for the
roof-mounted side impact airbag. Do not open or
break the airbag coverings.

Section 2 Features and Controls
2-2

Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is in all the way. If
none of this works, then your vehicle needs service.
A (OFF):This is the only position in which the ignition
key can be inserted or removed. This position locks
the ignition and transaxle. It is a theft-deterrent feature.B (ACCESSORY):This position lets the radio and
windshield wipers operate while the engine is off. To use
ACCESSORY, turn the key clockwise.
C (RUN):This position is where the key returns to after
the vehicle is started. This position displays some of
the warning and indicator lights.
D (START):This position starts the engine.
A warning chime will sound and the Driver Information
Center (DIC) will display DRIVER’S DOOR OPEN when
the driver’s door is opened if the ignition is in OFF,
ACCESSORY and the key is in the ignition. SeeDIC
Warnings and Messages on page 3-56for more
information.
Retained Accessory Power (RAP)
After you turn the ignition off and remove the key, you
will still have power to such accessories as the
power windows, clock, radio, and if the vehicle has
them, audio steering wheel controls and sunroof. The
power to the accessories can last up to 10 minutes. The
instrument panel cluster lights will stay on for a few
seconds, then will go out. Once you open a door, the
power will shut off. Your vehicle has a feature designed
to protect the battery against drainage. For more
information seeInadvertent Power Battery Saver on
page 3-18.
2-22

Rear Seat Armrest
Your vehicle has a rear seat armrest with cupholders.
To access, pull the tab on the armrest forward.
Convenience Net
The vehicle may have a convenience net located on the
back wall of the trunk.
The net is not for larger, heavier loads. Store those in
the trunk as far forward as possible.
Unhook the net so that it will lie at when not in use.
Sunroof
Your vehicle may be equipped with a power sunroof.
The sunroof buttons are
located on the headliner.To express-open the sunroof press and release the rear
of the driver’s side button. To stop the sunroof from
express opening, press the button again. If the
sunshade is in the closed position, it will open with the
sunroof, or it can be opened manually.
To close the sunroof, press and release the front of the
driver’s side button.
To vent the sunroof press and hold the back of the
passenger’s side button until the vent reaches the
desired position. Press the front of the passenger’s side
button to close the sunroof.
If an object is in the path of the sunroof while it is
closing, the anti-pinch feature will detect the object and
stop the sunroof from closing at the point of the
obstruction. The sunroof will then return to the full-open
or vent position.
Vehicle Personalization
In addition to the following features, your vehicle may
also have features that can be programmed through the
Driver Information Center (DIC). SeeDIC Vehicle
Customization on page 3-65for more information.
