2006 Buick LaCrosse Owner ManualM

In many crashes severe enough to inate an airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the right front passenger airbag.
Airbags are designed to inate only once. After
they inate, you will need some new parts for
your airbag system. If you do not get them, the
airbag system will not be there to help protect
you in another crash. A new system will include
airbag modules and possibly other parts. The
service manual for your vehicle covers other
parts that need to be replaced.
Your vehicle has a crash sensing and diagnostic
module which records information after a crash.
SeeVehicle Data Collection and Event Data
Recorders on page 7-10.
Let only qualied technicians work on your airbag
system. Improper service can mean that your
airbag system will not work properly. See your
GM dealer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system. The
passenger airbag status indicator on the instrument
panel will be visible when you turn your ignition key
to RUN or START. The words ON and OFF will
be visible during the system check. If you use remote
start to start your vehicle from a distance, if equipped,
you may not see the system check. When the
system check is complete, either the word ON or the
word OFF will be visible. SeePassenger Airbag Status
Indicator on page 3-35.
The passenger sensing system will turn off the right
front passenger’s frontal airbag under certain conditions.
The driver’s airbags are not part of the passenger
sensing system.Passenger Airbag

be blocking the signal. Take a few steps to the left
or right, hold the transmitter higher, and try again.

to match the new transmitter. Once your dealer has
coded the new transmitter, the lost transmitter will not
unlock your vehicle. The vehicle can have a maximum of
four transmitters matched to it.

Remote Vehicle Start
Your vehicle may have a remote starting feature. This
feature allows you to start the engine from outside of the
vehicle. It may also start up the vehicle’s heating or air
conditioning systems and rear window defogger. When
the remote start system is active, the climate control
system will heat and cool the inside of the vehicle based
on the outside temperature. The rear window defogger
will be turned on by the climate control system when it is
heating the inside of the vehicle. Normal operation of the
system will return after the key is turned to the RUN
position.
Laws in some communities may restrict the use of remote
starters. For example, some laws may require a person
using remote start to have the vehicle in view when doing
so. Check local regulations for any requirements on
remote starting of vehicles.
Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.The remote start feature provides two separate starts
per ignition cycle, each with 10 minutes of engine
running time.
The remote vehicle start feature needs to be reset
after your vehicle’s engine is started two times using
the transmitter’s remote start button. The remote start
system is reset by inserting the vehicle’s key into the
ignition switch and turning it to RUN. SeeIgnition
Positions on page 2-23for information regarding the
ignition positions on your vehicle.
Your remote keyless entry transmitter with the remote
start button provides an increased range of operation.
You can start your vehicle from an average range of
approximately 492 feet (150 m) away. However the
range may be less while the vehicle is running, and as
a result, you may need to be closer to your vehicle to
turn it off than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry System on page 2-3for additional information.
