2006 GMC Sierra Owner ManualM
Page 67 of 600
Never put a rear facing child restraint in the right front
passenger’s seat unless the airbag is off. Here is why:
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag in ates. This is because
the back of the rear-facing child restraint
would be very close to the in ating airbag. Be
sure the airbag is off before using a rear-facing
child restraint in the right front seat position. If
you secure a forward-facing child restraint in
the right front seat, always move the right front
passenger seat as far back as it will go.
A rear seat is a safer place to secure a forward facing
child restraint. SeeWhere to Put the Restraint on
page 1-40. If you need to secure a forward-facing child
restraint in the right front seat position, move the
seat as far back as it will go before securing a
forward-facing child restraint. SeeManual Seats on
page 1-3orPower Seats on page 1-4.
{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on when you have
turned off the airbag, it means that something
may be wrong with the airbag system. The
right front passenger’s airbag could in ate
even though the switch is off. If this ever
happens, have the vehicle serviced promptly.
Until you have the vehicle serviced, do not let
anyone whom the national government has
identi ed as a member of a passenger airbag
risk group sit in the right front passenger’s
position (for example, do not secure a
rear-facing child restraint in the right front
passenger’s seat). SeeAirbag Off Switch on
page 1-78.
If your child restraint is equipped with the LATCH
system, seeLower Anchors and Tethers for Children
(LATCH) on page 1-42.

{CAUTION:
When an airbag in ates, 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
in ates, 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.In many crashes severe enough to in ate an airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger airbag.Airbags are designed to in ate only once. After an
airbag in ates, 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 the need to
replace other parts.
Your vehicle is equipped with a crash sensing and
diagnostic module which records information after
a crash. SeeVehicle Data Collection and Event
Data Recorders on page 7-9.
Let only quali ed technicians work on your airbag
system. Improper service can mean that your
airbag system will not work properly. See your
dealer for service.

To turn off the right front passenger’s airbag, insert your
ignition key into the switch, push in, and move the
switch to the off position.
The airbag off light will come on to let you know that the
right front passenger’s airbag is off. The light will stay
on to remind you that the airbag is off. The right
front passenger’s airbag will remain off until you turn it
back on.
{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the airbag, it means
that something may be wrong with the airbag
system. The right front passenger’s airbag
could in ate even though the switch is off.
If your vehicle is a regular cab pickup or an
extended cab pickup and this ever happens,
do not let anyone whom the national
government has identi ed as a member of a
passenger airbag risk group sit in the right
front passenger’s position (for example, do not
secure a rear-facing child restraint in your
vehicle) until you have your vehicle serviced. United States

{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on, it
means that something may be wrong with the
airbag system. If this ever happens, have the
CAUTION: (Continued)
CAUTION: (Continued)
vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the frontal airbag. SeeAirbag Readiness
Light on page 3-35for more on this, including
important safety information.
Aftermarket equipment, such as seat covers, can affect
how well the passenger sensing system operates.
You may want to consider not using seat covers or other
aftermarket equipment if your vehicle has the passenger
sensing system. SeeAdding Equipment to Your
Airbag-Equipped Vehicle on page 1-86for more
information about modi cations that can affect how the
system operates.
{CAUTION:
Stowing of articles under the passenger’s seat
or between the passenger’s seat cushion and
seatback may interfere with the proper
operation of the passenger sensing system.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. You do not want the system to
in ate while someone is working on your vehicle. Your
dealer and the service manual have information
about servicing your vehicle and the airbag system. To
purchase a service manual, seeService Publications
Ordering Information on page 7-15.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
airbag can still in ate during improper service.
You can be injured if you are close to an
airbag when it in ates. 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 quali ed to do so.
The airbag system does not need regular maintenance.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front 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, front end sheet metal or
height, 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 7-2

double-sided key for the
ignition and all door locks
as well as the spare tire
hoist lock, if equipped.
If you ever lose your keys, your dealer will be able to
assist you with obtaining replacements.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
If you ever do get locked out of your vehicle, call the GM
Roadside Assistance Center. SeeRoadside Assistance
Program on page 7-6. If your vehicle is equipped with the
OnStar

your keys inside the vehicle, OnStar®may be able to
send a command to unlock your vehicle. SeeOnStar®
System on page 2-73for more information.

At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.
Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.
Check to determine if battery replacement or
resynchronization is necessary. See “Battery
Replacement” and “Resynchronization” under
Remote Keyless Entry System Operation on
page 2-5.
If you are still having trouble, see your dealer or a
quali ed technician for service.
