ECU GMC YUKON DENALI 2007 Owner's Manual

Securing a Child Restraint in the
Right Front Seat Position
Your vehicle has a right front passenger’s
airbag. A rear seat is a safer place to secure a
forward-facing child restraint. SeeWhere to
Put the Restraint on page 72.
In addition, your vehicle has a passenger sensing
system. The passenger sensing system is
designed to turn off the right front passenger’s
frontal airbag when an infant in a rear-facing infant
seat or a small child in a forward-facing child
restraint or booster seat is detected. See
Passenger Sensing System on page 101and
Passenger Airbag Status Indicator on page 230
for more information on this including important
safety information.
A label on your sun visor 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:
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 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 secured
in the rear seat, even if the airbag is off.
86

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 9.
If your child restraint has the LATCH system,
seeLower Anchors and Tethers for Children
(LATCH) on page 74.
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 74if
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 101. 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 9.
When the passenger sensing system has
turned off the right front passenger’s frontal
airbag, the off indicator on the passenger
airbag status indicator should light and stay
lit when you turn the ignition to RUN or
START. SeePassenger Airbag Status
Indicator on page 230.
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.
87

6. To tighten the belt, push down on the child
restraint, pull the shoulder portion of the belt
to tighten the lap portion of the belt and
feed the shoulder belt back into the retractor.
If you are using a forward-facing child
restraint, you may nd it helpful to use your
knee to push down on the child restraint
as you tighten the belt. You should not be able
to pull more of the belt from the retractor
once the lock has been set.
7. Push and pull the child restraint in different
directions to be sure it is secure.8. If the airbag is off, the off indicator will be lit
and stay lit when the key is turned to RUN
or START.
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.
89

{CAUTION:
Anyone who is up against, or very close
to, any airbag when it inates can be
seriously injured or killed. Airbags plus
lap-shoulder belts offer the best
protection for adults, but not for young
children and infants. Neither the vehicle’s
safety belt system nor its airbag system is
designed for them. Young children and
infants need the protection that a child
restraint system can provide. Always
secure children properly in your vehicle.
To read how, seeOlder Children on
page 61orInfants and Young Children on
page 64.
Occupants should not lean on or sleep
against the door in the rst or second row
seats, or the rear windows in the third row
seat, if your vehicle has roof-mounted
rollover airbags.There is an airbag
readiness light on the
instrument panel cluster,
which shows the
airbag symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an
electrical problem. SeeAirbag Readiness Light on
page 229for more information.
92

If your vehicle has a third row seat, the
roof-mounted rollover airbag is located in the
ceiling above the rear windows for the outside
passenger positions.
{CAUTION:
If something is between an occupant and
an airbag, the bag 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. And, if your vehicle
has roof-mounted rollover airbags, 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 side
impact airbag will be blocked. The path of
an inating airbag must be kept clear.
95

The passenger sensing system works with
sensors that are part of the right front passenger’s
seat and safety belt. The sensors are designed
to detect the presence of a properly-seated
occupant and determine if the passenger’s airbag
should be enabled (may inate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. We recommend that child restraints be
secured in a rear seat, including an infant riding
in a rear-facing infant seat, a child riding in a
forward-facing child seat, and an older child riding
in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor 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:
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 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 secured
in the rear seat, even if the airbag is off.

102

CAUTION: (Continued)
If you need to secure a forward-facing
child restraint in the right front seat,
always move the front passenger seat as
far back as it will go. It is better to secure
the child restraint in a rear seat.
The passenger sensing system is designed to turn
off the right front passenger’s airbag if:
the right front passenger seat is unoccupied
the system determines that an infant is present
in a rear-facing infant seat
the system determines that a small child is
present in a forward-facing child restraint
the system determines that a small child is
present in a booster 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 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
on page 86.
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.
103

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.
The passenger sensing system is designed to
enable (may inate) the right front passenger’s
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 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.
If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it
could be because that person is not sitting properly
in the seat. If this happens, turn the vehicle off
and ask the person to place the seatback in
the fully upright position, then sit upright in theseat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the
vehicle and have the person remain in this position
for about two minutes. This will allow the system
to detect that person and then enable the
passenger’s airbag.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides 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, height,
front end or side sheet metal, 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 570.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, rollover sensor
module, instrument panel, steering wheel,
ceiling headliner, ceiling and pillar garnish trim,
roof-mounted rollover airbag modules, 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 570.
