ECU GMC YUKON 2013 Owner's Guide

Black plate (50,1)GMC Yukon/Yukon XL Owner Manual - 2013 - CRC 2nd edition - 8/15/12
3-50 Seats and Restraints
We recommend that children and
child restraints be secured in a rear
seat, including: an infant or a child
riding in a rear-facing child restraint;
a child riding in a forward-facing
child seat; an older child riding in a
booster seat; and children, who are
large enough, using safety belts.
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.
{WARNING
A child in a rear-facing child
restraint can be seriously injured
or killed if the right front
passenger airbag inflates. This is
because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the right front

WARNING (Continued)
passenger airbag inflates and the
passenger seat is in a forward
position.
The vehicle may have a
passenger sensing system which
is designed to turn off the right
front passenger frontal airbag
under certain conditions.
Even if the passenger sensing
system, if equipped, 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(Continued)
WARNING (Continued)
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 3‑36 for additional
information.
{WARNING
A child in a child restraint in the
center front seat can be badly
injured or killed by the frontal
airbags if they inflate. Never
secure a child restraint in the
center front seat. It is always
better to secure a child restraint in
a rear seat.

Black plate (51,1)GMC Yukon/Yukon XL Owner Manual - 2013 - CRC 2nd edition - 8/15/12
Seats and Restraints 3-51
Do not use child restraints in the
center front seat position.
When securing a child restraint in a
rear seating position, study the
instructions that came with your
child restraint to make sure it is
compatible with this vehicle.
Child restraints and booster seats
vary considerably in size, and some
may fit in certain seating positions
better than others. Always make
sure the child restraint is properly
secured.
Depending on where you place the
child restraint and the size of the
child restraint, you may not be able
to access adjacent safety belt
assemblies or LATCH anchors for
additional passengers or child
restraints. Adjacent seating
positions should not be used if the
child restraint prevents access to or
interferes with the routing of the
safety belt.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
your vehicle
—even when no child
is in it.
Lower Anchors and
Tethers for Children
(LATCH System)
The LATCH system secures a child
restraint during driving or in a crash.
LATCH attachments on the child
restraint are used to attach the child
restraint to the anchors in the
vehicle. This system is designed to
make installation of a child restraint
easier.
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.

Black plate (52,1)GMC Yukon/Yukon XL Owner Manual - 2013 - CRC 2nd edition - 8/15/12
3-52 Seats and Restraints
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.
Some child restraints with top
tethers are designed for use with or
without the top tether being
attached. Others require the top
tether always to be attached. In
Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached. Be sure to read and follow
the instructions for your child
restraint.

3-54 Seats and Restraints
To assist in locating the top tether
anchors, the top tether anchor
symbol appears near the anchors.
Second Row Seat—Bucket
For models with bucket second row
seating, the top tether anchors are
at the bottom rear of the seat
cushion for each seating position in
the second row. Be sure to use an anchor on the same side of the
vehicle as the seating position
where the child restraint will be
placed.
Second Row Seat
—60/40
For models with 60/40 second row
seating, the top tether anchors are
at the bottom rear of the seat
cushion for each seating position in
the second row. Be sure to use an
anchor on the same side of the
vehicle as the seating position
where the child restraint will be
placed.
Third Row Seat
For vehicles with a third row seat,
there is one top tether anchor at the
bottom rear of the seat cushion that
can be used for either the third row
center or driver side seating
position. 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

Black plate (55,1)GMC Yukon/Yukon XL Owner Manual - 2013 - CRC 2nd edition - 8/15/12
Seats and Restraints 3-55
the instructions that come with the
child restraint say that the top tether
must be attached.
According to accident statistics,
children and infants are safer when
properly restrained in a child
restraint system or infant restraint
system secured in a rear seating
position. SeeWhere to Put the
Restraint on page 3‑49 for
additional information.
Securing a Child Restraint
Designed for the LATCH
System
{WARNING
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 safety

belts to secure the restraint,
following the instructions that
came with the child restraint and
the instructions in this manual.
{WARNING
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.
{WARNING
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. Pull
the shoulder belt all the way out
of the retractor to set the lock,
if the 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.

3-56 Seats and Restraints
If you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint on
page 3‑49.
This system is designed to make
installation of child restraints easier.
When using lower anchors, do not
use the vehicle's safety belts.
Instead use the vehicle's anchors
and child restraint attachments to
secure the restraints. Some
restraints also use another vehicle
anchor to secure a top tether.
1. Attach and tighten the lowerattachments 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 the top 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. Put the child restraint on the seat.
1.3. 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 equipped. Refer to the
child restraint instructions and
the following steps:
2.1. Find the top tether anchor.
2.2. 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.
.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 an adjustable headrest
or head restraint and you
are using a single tether,
raise the headrest or head
restraint and route the
tether under the headrest or
head restraint and in
between the headrest or
head restraint posts..If the position you are using
has a fixed headrest or
head restraint and you are
using a single tether, route
the tether around the
inboard or outboard side of
the headrest or head
restraint.
.If the position you are using
has a fixed or an adjustable
headrest or head restraint
and you are using a dual
tether, route the tether
around the headrest or
head restraint.
3. Before placing a child in the child restraint, make sure it is
securely held in place. To check,
grasp the child restraint at the
LATCH path and attempt to
move it side to side and back
and forth. There should be no
more than 2.5 cm (1 in) of
movement, for proper
installation.

Replacing LATCH System
Parts After a Crash
{WARNING
A crash can damage the LATCH
system in the vehicle. A damaged
LATCH system may not properly
secure the child restraint,
resulting in serious injury or even
death in a crash. To help make
sure the LATCH system is
working properly after a crash,
see your dealer to have the
system inspected and any
necessary replacements made as
soon as possible.
If the vehicle has the LATCH system
and it was being used during a
crash, new LATCH system parts
may be needed.
New parts and repairs may be
necessary even if the LATCH
system was not being used at the
time of the crash.
Securing Child Restraints
(Center Front Seat
Position)
{WARNING
A child in a child restraint in the
center front seat can be badly
injured or killed by the frontal
airbags if they inflate. Never
secure a child restraint in the
center front seat. It is always
better to secure a child restraint in
a rear seat.
Do not use child restraints in the
center front seat position.
Securing Child Restraints
(Right Front Seat
Position)
This vehicle has airbags. A rear
seat is a safer place to secure a
forward-facing child restraint. See
Where to Put the Restraint on
page 3‑49.
In addition, the vehicle may have a
passenger sensing system which is
designed to turn off the right front
passenger frontal airbag under
certain conditions. See Passenger
Sensing System on page 3‑36 and
Passenger Airbag Status Indicator
on page 5‑17 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.

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 3‑36 for additional
information.
If the child restraint has the LATCH
system, see Lower Anchors and
Tethers for Children (LATCH
System) on page 3‑51 for how and
where to install the child restraint
using LATCH. If a child restraint is secured using a safety belt and it
uses a top tether, see
Lower
Anchors and Tethers for Children
(LATCH System) on page 3‑51 for
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.
You will be using the lap-shoulder
belt to secure the child restraint in
this position. Follow the instructions
that came with the child restraint.
1. Move the seat as far back as it will go before securing the
forward-facing child restraint.
2. Put the child restraint on the seat.

7. Before placing a child in thechild restraint, make sure it is
securely held in place. To check,
grasp the child restraint at the
safety belt path and attempt to
move it side‐to‐side and back‐
and‐forth. When the child
restraint is properly installed,
there should be no more than
2.5 cm (1 in) of movement.
If the vehicle is equipped with the
passenger sensing system, and
when the passenger sensing system
has turned off the right front
passenger frontal airbag, the off
indicator in the passenger airbag
status indicator should light and stay
lit when you start the vehicle. See
Passenger Airbag Status Indicator
on page 5‑17.
If a child restraint has been installed
and the on indicator is lit, see “If the
On Indicator is Lit for a Child
Restraint” underPassenger Sensing
System on page 3‑36 for more
information. To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
Securing Child Restraints
(Rear Seat)
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, see
Lower Anchors and
Tethers for Children (LATCH
System) on page 3‑51 for 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,
see Lower Anchors and Tethers for
Children (LATCH System) on
page 3‑51 for 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 read
Where to Put
the Restraint on page 3‑49.
The vehicle's lap-shoulder belts for
the first and second row seating
positions are equipped with
free-falling latch plates. If the
vehicle has a third row, the
lap-shoulder belts have cinching
latch plates.
