2007 GMC SIERRA CLASSIC child 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 passenger’s frontal airbag, the off indicator will
light and stay lit to remind you that the airbag is off.
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 following the child restraint
manufacturer’s directions and refer toSecuring a
Child Restraint in the Right Front Seat Position
(Regular and Extended Cab) (With Passenger
Sensing System)in the Index.
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 if
one is available and check with your dealer.
The passenger sensing system is designed to
enable (may inate) the right front passenger’s
frontal airbag anytime the system senses
that a person of adult size is sitting properly in the
right front passenger’s seat. When the passenger
sensing system has allowed the airbag to be
enabled, the on indicator will light and stay lit to
remind you that the airbag is 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’s frontal airbag, depending
upon the person’s seating posture and body build.
Everyone in your vehicle who has outgrown
child restraints should wear a safety belt
properly — whether or not there is an airbag for
that person.

{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 inate even
though the switch is off.
If your vehicle is a regular cab pickup and
this ever happens, do not let anyone
whom the national government has
identied 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.
CAUTION: (Continued)
CAUTION: (Continued)
If your vehicle is an extended cab pickup
and this ever happens, do not let anyone
whom the national government has
identied as a member of the 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) until you
have your vehicle serviced.

Passenger Airbag Status Indicator
If your vehicle has the passenger sensing system,
your rearview mirror will have a passenger
airbag status indicator.
When the ignition key is turned to RUN or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check. Then,
after several more seconds, the status indicatorwill light either ON or OFF, or either the on or off
symbol to let you know the status of the right
front passenger’s frontal airbag.
Your vehicle may have a label on your sun visor
that says, “Never put a rear-facing child seat in the
front.” This is because the risk to the rear-facing
child is so great, if the airbag deploys.
{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint, no
system is failsafe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.United States

Never put a child in a rear-facing child restraint in
the right front passenger seat the unless
passenger airbag status indicator shows off. Never
put a rear facing child restraint in the right front
passenger seat unless the airbag is off. Here
is why:
{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint, no
system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be
transported in vehicles with a rear seat
that will accommodate a rear-facing child
restraint, whenever possible.If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger’s frontal airbag is enabled
(may inate).
{CAUTION:
If the on indicator comes on when you have
a rear-facing child restraint installed in the
right front passenger’s seat, it means that
the passenger sensing system has not
turned off the passenger’s frontal airbag.
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.
251

If you put things inside your vehicle — like
suitcases, tools, packages, or anything
else — they go as fast as the vehicle goes.
If you have to stop or turn quickly, or if there
is a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can
strike and injure people in a sudden stop
or turn, or in a crash.
Put things in the cargo area of your
vehicle. Try to spread the weight
evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops of
the seats.
CAUTION: (Continued)
CAUTION: (Continued)

Do not leave an unsecured child
restraint in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down
unless you need to.
There is also important loading information for
off-road driving in this manual. See “Loading Your
Vehicle for Off-Road Driving“ underOff-Road
Driving on page 372.
