2009 GMC ACADIA ECU

A label on the sun visor says,
“Never put a rear-facing child
restraint 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
airbag inates. This is because the
back of the rear-facing child
restraint would be very close to the
inating airbag. A child in a
forward-facing child restraint can
be seriously injured or killed if the
right front passenger airbag
inates and the passenger seat is
in a forward position.
(Continued)
CAUTION (Continued)
Even if the passenger sensing
system has turned off the right
front passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though it is
turned off.
Secure rear-facing child restraints
in a rear seat, even if the airbag is
off. If you 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.
SeePassenger Sensing System
on page 1-55for additional
information.When securing a child restraint in a
rear seating position, study the
instructions that came with the child
restraint to make sure it is compatible
with this vehicle.
Wherever a child restraint is
installed, be sure to secure the child
restraint properly.
Keep in mind that an unsecured child
restraint can move around in a
collision or sudden stop and injure
people in the vehicle. Be sure to
properly secure any child restraint
in the vehicle — even when no child
is in it.
1-36 Seats and Restraint System

Lower Anchors and
Tethers for Children
(LATCH)
The LATCH system holds a child
restraint during driving or in a crash.
This system is designed to make
installation of a child restraint easier.
The LATCH system uses anchors
in the vehicle and attachments
on the child restraint that are made
for use with the LATCH system.
Make sure that a LATCH-compatible
child restraint is properly installed
using the anchors, or use the
vehicle’s safety belts to secure the
restraint, following the instructions
that came with that restraint, and
also the instructions in this manual.
When installing a child restraint with
a top tether, you must also use either
the lower anchors or the safety belts
to properly secure the child restraint.
A child restraint must never be
attached using only the top tether
and anchor.In order to use the LATCH system in
your vehicle, you need a child
restraint that has LATCH
attachments. The child restraint
manufacturer will provide you with
instructions on how to use the child
restraint and its attachments. The
following explains how to attach a
child restraint with these attachments
in your vehicle.
Not all vehicle seating positions or
child restraints have lower anchors
and attachments or top tether
anchors and attachments.
Lower Anchors
Lower anchors (A) are metal bars
built into the vehicle. There are
two lower anchors for each
LATCH seating position that will
accommodate a child restraint
with lower attachments (B).Top Tether Anchor
A top tether (A, C) anchors the
top of the child restraint to the
vehicle. A top tether anchor is built
into the vehicle. The top tether
attachment (B) on the child restraint
connects to the top tether anchor
in the vehicle in order to reduce the
forward movement and rotation
of the child restraint during driving
or in a crash.
Your child restraint may have a
single tether (A) or a dual tether (C).
Either will have a single
attachment (B) to secure the
top tether to the anchor.
Seats and Restraint System 1-37

The third row has one top tether
anchor located at the bottom rear of
the center seatback. This anchor
should be used for the center
seating position only. Never install
two top tethers using the same
top tether anchor.
Do not secure a child restraint in a
position without a top tether
anchor 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.Accident statistics show that children
are safer if they are restrained in the
rear rather than the front seat. See
Where to Put the Restraint on
page 1-35for additional information.
Securing a Child Restraint
Designed for the LATCH System
{CAUTION
If a LATCH-type child restraint is
not attached to anchors, the child
restraint will not be able to protect
the child correctly. In a crash, the
child could be seriously injured or
killed. Install a LATCH-type child
restraint properly using the
anchors, or use the vehicle’s
safety belts to secure the restraint,
following the instructions that came
with the child restraint and the
instructions in this manual.
{CAUTION
Do not attach more than one child
restraint to a single anchor.
Attaching more than one child
restraint to a single anchor could
cause the anchor or attachment to
come loose or even break during
a crash. A child or others could
be injured. To reduce the risk of
serious or fatal injuries during a
crash, attach only one child
restraint per anchor.
{CAUTION
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck and the
safety belt continues to tighten.
Buckle any unused safety belts
behind the child restraint so
children cannot reach them.

1-40 Seats and Restraint System

CAUTION (Continued)
Pull the shoulder belt all the way
out of the retractor to set the lock,
if your vehicle has one, after the
child restraint has been installed.
Notice:Do not let the LATCH
attachments rub against the
vehicle’s safety belts. This may
damage these parts. If necessary,
move buckled safety belts to avoid
rubbing the LATCH attachments.
Do not fold the empty rear seat
with a safety belt buckled. This
could damage the safety belt or
the seat. Unbuckle and return the
safety belt to its stowed position,
before folding the seat.
1. Attach and tighten the lower
attachments to the lower
anchors. If the child restraint
does not have lower attachments
or the desired seating position
does not have lower anchors,
secure the child restraint with thetop tether and the safety belts.
Refer to your child restraint
manufacturer instructions and the
instructions in this manual.
1.1. Find the lower anchors for
the desired seating position.
1.2. Recline the seatback to the
full reclined position.
Make sure the second row
bench seatbacks are
aligned at the same angle
before placing the child
restraint on the seat. Make
sure the third row bench
seatbacks are both upright
before placing the child
restraint on the seat.
1.3. Put the child restraint on
the seat.
1.4. Attach and tighten the lower
attachments on the child
restraint to the lower
anchors.
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 the vehicle has one.Refer to the child restraint
instructions and the following
steps:
2.1. Find the top tether anchor.
2.2. If the anchor is covered,
ip open the cover to
expose the anchor.
2.3. Route, attach and tighten
the top tether according to
your child restraint
instructions and the
following instructions:
If the position you are using
does not have a headrest or
head restraint and you are
using a single tether, route
the tether over the seatback.
Seats and Restraint System 1-41

If the position you are using
does not have a headrest or
head restraint and you are
using a dual tether, route the
tether over the seatback.If the position you are using
has a xed headrest or head
restraint and you are using a
dual tether, route the tether
around the headrest or head
restraint.If the position you are using
has a xed headrest or head
restraint and you are using a
single tether, route the tether
over the headrest or 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
Seat Position
When securing a child restraint in a
rear seating position, study the
instructions that came with the child
restraint to make sure it is
compatible with this vehicle.
If the child restraint has the LATCH
system, seeLower Anchors and
Tethers for Children (LATCH)
on page 1-37for how and where to
install the child restraint using
LATCH. If a child restraint is secured
in the vehicle using a safety belt
and it uses a top tether, seeLower
Anchors and Tethers for Children
(LATCH) on page 1-37for top tether
anchor locations.
Do not secure a child seat in a
position without a top tether anchor
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
strap must be anchored.In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether
be attached.
If the child restraint does not have
the LATCH system, you will be using
the safety 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.
If more than one child restraint
needs to be installed in the
rear seat, be sure to readWhere to
Put the Restraint on page 1-35.
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. Push the latch plate into the
buckle until it clicks.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.

4. Pull the rest of the shoulder belt
all the way out of the retractor to
set the lock.5. 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. When installing
a forward-facing child restraint, it
may be helpful to use your knee
to push down on the child
restraint as you tighten the belt.6. If the child restraint has a top
tether, follow the child restraint
manufacturer’s instructions
regarding the use of the top
tether. SeeLower Anchors and
Tethers for Children (LATCH)
on page 1-37for more
information.
7. Push and pull the child restraint
in different directions to be sure
it is secure.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it.
1-44 Seats and Restraint System

Securing a Child
Restraint in the Right
Front Seat Position
The vehicle has airbags. A rear
seat is a safer place to secure
a forward-facing child restraint.
SeeWhere to Put the Restraint
on page 1-35.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the right
front passenger frontal airbag and
seat-mounted side impact airbag
under certain conditions. See
Passenger Sensing System on
page 1-55andPassenger Airbag
Status Indicator on page 3-36
for more information, including
important safety information.
A label on the 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
airbag inates. This is because the
back of the rear-facing child
restraint would be very close to the
inating airbag. A child in a
forward-facing child restraint can
be seriously injured or killed if the
right front passenger airbag
inates and the passenger seat is
in a forward position.
Even if the passenger sensing
system has turned off the right
front passenger frontal airbag, no
system is fail-safe. No one can
