2006 GMC ENVOY DENALI ECU

2. If the child restraint manufacturer recommends that
the top tether be attached, attach and tighten the
top tether to the top tether anchor, if equipped.
Refer to the child restraint instructions and
the following steps:
2.1. Find the top tether anchor.
2.2. Route and tighten the top tether according to
your child restraint instructions and the
following instructions. For ve-passenger
vehicles, if your vehicle is equipped with a
cargo shade, route the top tether between
the seatback and the cargo shade.
If the position you are
using does not have a
head restraint and you are
using a single tether,
route the tether over
the seatback.
If the position you are
using does not have a
head restraint and you
are using a dual tether,
route the tether over
the seatback.For ve-passenger
vehicles that have a head
restraint, fold down the
head restraint and
route the single tether
under the head restraint
and in between the
head restraint posts.
SeeRear Seat Operation on page 1-9.
For seven-passenger vehicles that have
adjustable head restraints, raise the
head restraint and route the single tether
under the head restraint and in between the
head restraint posts.
If the position you are
using has a head restraint
and you are using a
dual tether, route the tether
around the head restraint.
3. Push and pull the child restraint in different
directions to be sure it is secure.

Securing a Child Restraint in a Rear
Outside Seat Position
If your child restraint is equipped with the LATCH
system, seeLower Anchors and Tethers for Children
(LATCH) on page 1-43.
There are no top tether anchors at the third row seating
positions (if equipped). Do not secure a child seat in
these positions 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.
If your child restraint does not have the LATCH system,
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. Put the child restraint on the seat.
2. 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.3. 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.

6. If your child restraint manufacturer recommends
using a top tether, and the position that you are
using has a top tether anchor, attach and tighten the
top tether to the top tether anchor. Refer to the
instructions that came with the child restraint and to
Lower Anchors and Tethers for Children (LATCH)
on page 1-43.
7. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, if the top tether is attached
to the top tether anchor, disconnect it. 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.
Securing a Child Restraint in the
Center Rear Seat Position
Many child restraints are too wide to be correctly
secured in the center rear seat, although some of them
will t there. If the center seat position is too narrow
for your child restraint, secure it in a rear outside
seat position.
If you secure a child restraint in the center seat position,
follow the instructions inSecuring a Child Restraint in
a Rear Outside Seat Position on page 1-51.
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 1-42.
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. SeePassenger Sensing System on page 1-67
andPassenger Airbag Status Indicator on page 3-36
for more information on this including important
safety information.
1-53

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.
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.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 1-3orManual
Seats on page 1-2.
If your child restraint is equipped with the LATCH
system, seeLower Anchors and Tethers for Children
(LATCH) on page 1-43.
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 1-43if 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 1-67. 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 1-3orManual
Seats on page 1-2.
When the passenger sensing system has turned off
the right front passenger’s frontal airbag, the off
indicator in 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 3-36.
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.
1-55

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 in the rearview
mirror 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.

{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 1-32orInfants and
Young Children on page 1-34.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 3-35
for more information.
1-60

{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 side impact airbags, never
secure anything to the roof of your vehicle by
routing the rope or tiedown 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.
When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal or
near-frontal crashes. But they are designed to inate only
if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account a
variety of desired deployment and non-deployment
events and are used to predict how severe a crash is
likely to be in time for the airbags to inate and help
restrain the occupants. Whether your frontal airbags will
or should deploy is not based on how fast your vehicle is
traveling. It depends largely on what you hit, the direction
of the impact and how quickly your vehicle slows down.
In addition, your vehicle has “dual stage” frontal airbags,
which adjust the restraint according to crash severity.
Your vehicle is equipped with electronic frontal sensors,
which help the sensing system distinguish between a
moderate frontal impact 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 9 to 16 mph (14
to 26 km/h), and the threshold level for a full deployment
is about 18 to 25 mph (29 to 40 km/h). (The threshold
level can vary, however, with specic vehicle design, so
that it can be somewhat above or below this range.)
