seats GMC SIERRA CLASSIC 2007 Owner's Manual

For regular cab models with a bench seat, the top
tether anchors are located under trim covers on the
back panel behind the center and passenger seats.
Do not install a child restraint in the center seat
position. SeeSecuring a Child Restraint in the
Center Front Seat Position on page 74for more
information. For regular cab models with bucket
seats, the top tether anchor is located under a trim
covers on the back panel behind the passenger
seat. Remove the trim plug to access the anchor.For extended cab models, the top tether anchors
are located near the top of the seatback for
each rear seating position. In addition to the
top tether anchors, each seating position has a
fabric loop at the top of the seatback that you will
use to route the top tether through. Be sure to
use an anchor located on the same side of
the vehicle as the seating position where the child
restraint will be placed.

For crew cab models, there are covered top tether
anchors for each seating position located on the
back panel of your vehicle, behind the rear
seat. Remove the trim covers to access the
anchors.Do not secure a child restraint in the front
passenger’s position if your vehicle has rear seats,
if a national or local law requires that the top
tether be attached, or if the instructions that come
with the child restraint say that the top tether
must be attached. There is no place to attach the
top tether in this position.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. SeeWhere to Put the Restraint on page 55
for additional information.

A rear seat is a safer place to secure a
forward-facing child restraint. If you need to
secure a forward-facing child restraint in the right
front seat position, seeWhere to Put the
Restraint on page 55.
If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children
(LATCH) on page 58.
There is no top tether anchor in the right front
passenger’s position. Do not secure a child seat in
this position if a national or local law requires
that the top tether be anchored, or if the
instructions that come with the child restraint say
that the top tether must be anchored. See
Lower Anchors and Tethers for Children (LATCH)
on page 58if your child restraint has a top
tether.You will be using the lap-shoulder belt to secure
the restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when
and as the instructions say.
1. Because your vehicle has a right front
passenger’s frontal airbag, always move
the seat as far back as it will go before
securing a forward-facing child restraint. See
Manual Seats on page 9orPower Seats
on page 10.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and
shoulder portions of the vehicle’s safety belt
through or around the restraint. The child
restraint instructions will show you how.
75

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 inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating 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 55. 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 gobefore securing a forward-facing child restraint.
SeeManual Seats on page 9orPower Seats
on page 10.
{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 inate 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 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 the right front
passenger’s seat). SeeAirbag Off Switch
on page 100.
80

If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children
(LATCH) on page 58.
If your vehicle has a rear seat, there is no top
tether anchor at the right front seating position. Do
not secure a child seat in this position if a
national or local law requires that the top tether be
anchored or if the instructions that come with
the child restraint say that the top tether must be
anchored. SeeLower Anchors and Tethers for
Children (LATCH) on page 58if the child restraint
has a top tether.You will be using the lap-shoulder belt to secure
the child restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s
frontal airbag. SeeAirbag Off Switch on
page 100. If your child restraint is
forward-facing, move the seat as far back as
it will go before securing the restraint in
this seat. SeeManual Seats on page 9or
Power Seats on page 10. If you need to use a
rear-facing child restraint in this seat, make
sure the airbag is off once the child restraint
has been installed.
When the airbag off switch has turned off the
right front passenger’s frontal airbag, the
off indicator in the airbag off light should light
and stay lit when you turn the ignition to
RUN or START. SeeAirbag Off Light on
page 248.
2. Put the child restraint on the seat.
81

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:
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. Be sure the airbag is off
before using a rear-facing child restraint
in the passenger’s position.
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag and side
CAUTION: (Continued)
CAUTION: (Continued)
impact airbag (if equipped) 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 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
the forward-facing child restraint. SeePower Seats
on page 10orManual Seats on page 9.
If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children
(LATCH) on page 58.
87

If your vehicle has a rear seat, there is no top
tether anchor at the right front seating position. Do
not secure a child seat in this position if a
national or local law requires that the top tether be
anchored or if the instructions that come with
the child restraint say that the top tether must be
anchored. SeeLower Anchors and Tethers for
Children (LATCH) on page 58if the child restraint
has a top tether.
You will be using the lap-shoulder belt to secure
the child restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s
frontal airbag. SeePassenger Sensing
System on page 103. We recommend that
rear-facing child restraints be secured in a rear
seat, even if the airbag is off. If your child
restraint is forward-facing, move the seat as
far back as it will go before securing the
child restraint in this seat. SeePower Seats
on page 10orManual Seats on page 9.
When the passenger sensing system has
turned off the right front passenger’s frontal
airbag, the off indicator in the passenger airbagstatus indicator should light and stay lit when
you turn the ignition to RUN or START.
SeePassenger Airbag Status Indicator on
page 250.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and
shoulder portions of the vehicle’s safety belt
through or around the restraint. The child
restraint instructions will show you how.
4. Buckle the belt. Make sure the release button
is positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.

Dual Stage Airbags
If your vehicle has frontal airbags with dual stage
deployment, the amount of restraint will adjust
according to crash severity. Your vehicle has
electronic frontal sensors which help the sensing
system distinguish between a moderate and a
more severe frontal impact. For moderate frontal
impacts, these airbags inate at a level less
than full deployment. For more severe frontal
impacts, full deployment occurs. If the front of your
vehicle goes straight into a wall that does not
move or deform, the threshold level for the
reduced deployment is about 10 to 16 mph
(16 to 25 km/h), and the threshold level for a full
deployment is about 20 to 30 mph (32 to 48 km/h).
The threshold level can vary, however, with
specic vehicle design, so that it can be somewhat
above or below this range.Vehicle’s with dual stage airbags also have
special sensors which enable the sensing system
to monitor the position of both the driver and
passenger front seats. The seat position sensor
provides information which is used to determine if
the airbags should deploy at a reduced level or
at full deployment.
What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag
sensing system detects that the vehicle is in a
crash. The sensing system triggers a release of gas
from the inator, which inates the airbag. The
inator, airbag, and related hardware are all part of
the airbag modules inside the steering wheel and in
the instrument panel in front of the right front
passenger.

Q:What if I added a snow plow? Will it keep
the airbags from working properly?
A:We have designed our airbag systems to work
properly under a wide range of conditions,
including snow plowing with vehicles that have
the optional Snow Plow Prep Package
(RPO VYU). But do not change or defeat the
snow plow’s “tripping mechanism.” If you
do, it can damage your snow plow and your
vehicle, and it may cause an airbag ination.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my advanced airbag
system?
A:Changing or moving any parts of the front
seats, safety belts, the airbag sensing and
diagnostic module, steering wheel, instrument
panel, the inside review mirror, or airbag
wiring can affect the operation of the airbag
system. 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. SeeCustomer
Satisfaction Procedure on page 638.

Outside Power Foldaway Mirrors
If your vehicle is
equipped with this
feature, the controls are
located on the driver’s
door armrest.
Move the upper selector switch to the left or right
to choose the mirror you want to adjust; then
press the dots located on the four-way control pad
to adjust the mirror.
The mirrors may also include a memory function
which works together with the memory seats.
SeeMemory Seat and Mirrors on page 12for more
information.To fold or unfold the mirrors, move the selector
switch, located above the mirror control, to
the middle position. The mirror control will
illuminate. Press the right or left side of the mirror
control to fold or unfold the mirrors. You may
notice the mirror glass adjust as the mirrors fold
in; this is normal. The mirror glass will reposition
itself once the mirrors are unfolded.
If the mirrors are accidentally folded/unfolded
manually, they may shake or utter at normal
driving speeds and may not stay in the unfolded
position. If this happens, you will need to reset the
mirrors. See “Resetting the Power Foldaway
Mirrors” next.
