50 Seats and Restraints
If the vehicle does not have a rear seat that
will accommodate a rear-facing child
restraint, a rear-facing child restraint should
not be secured in the vehicle, even if the
airbag is off.
{Warning
Never secure a rear-facing or
forward-facing child restraint in the left
rear seating position in an extended cab
model. This seating position is not
suitable for child restraint installation.
The seat cushion is too short to properly
support a rear-facing or forward-facing
child restraint. A child could be seriously
injured or killed in a sudden stop or
crash.
A rear-facing or forward-facing child
restraint can be installed in the right rear
seating position using the seat cushion
extension in an extended cab model.
Never install a child restraint in the right
rear seating position without the seat
cushion extension. SeeLower Anchors and
Tethers for Children (LATCH System) 050

Belt in the Rear Seat)064 or
Securing Child Restraints (With the Seat
Belt in the Front Seat) 069.
Never secure a rear-facing or forward-facing
child restraint in the left rear seating
position in an extended cab model.
When securing a child restraint with the
seat belts in a rear seat position, study the
instructions that came with the 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.
Do not install a child restraint in any rear
seating position where it cannot be installed
securely.
Depending on where you place the child
restraint and the size of the child restraint,
you may not be able to access adjacent seat
belts 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 seat belt. The seat in front of an installed child
restraint should be adjusted to ensure
proper installation according to the child
restraint manual.
Wherever a child restraint is installed, be
sure to follow the instructions that came
with the child restraint and 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.
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. The LATCH system is designed
to make installation of a child restraint
easier.
In order to use the LATCH system in your
vehicle, you need a child restraint that has
LATCH attachments. LATCH-compatible
rear-facing and forward-facing child seats can

GMC Canyon/Canyon Denali Owner Manual (GMNA-Localizing-U.S./Canada-
14430430) - 2021 - CRC - 9/9/20
Seats and Restraints 51
be properly installed using either the LATCH
anchors or the vehicle’s seat belts. Do not
use both the seat belts and the LATCH
anchorage system to secure a rear-facing or
forward-facing child seat.
Booster seats use the vehicle’s seat belts to
secure the child and the booster seat. If the
manufacturer recommends that the booster
seat be secured with the LATCH system, this
can be done as long as the booster seat can
be positioned properly and there is no
interference with the proper positioning of
the lap-shoulder belt on the child.
Make sure to follow the instructions that
came with the child 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 seat belts to properly secure
the child restraint. A child restraint must
never be attached using only the top tether.
For a forward-facing 5-pt harness child
restraint where the combined weight of the
child and restraint are up to 29.5 kg (65 lb),
use either the lower LATCH anchorages with
the top tether anchorage, or the seat belt
with the top tether anchorage. Where thecombined weight of the child and restraint
are greater than 29.5 kg (65 lb), use the seat
belt with the top tether anchorage only.

be labeled with the specific child weight up
to which the LATCH system can be used to
install the restraint.
The following explains how to attach a child
restraint with these attachments in the
vehicle. Not all vehicle seating positions have lower
anchors. In this case, the seat belt must be
used (with top tether where available) to
secure the child restraint. See

Lower Anchors
Lower anchors (1) 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 (2).
Top Tether Anchor
A top tether (3,4) is used to secure the top
of the child restraint to the vehicle. A top
tether anchor is built into the vehicle. The
top tether attachment hook (2) 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.
The child restraint may have a single
tether (3) or a dual tether (4). Either will
have a single attachment hook (2) 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 thetop 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.

Seats and Restraints 55
For extended cab without rear seat and crew
cab models, there are top tether anchor
symbols to assist you in locating the top
tether anchors.
Crew Cab
The top tether anchors in a crew cab model
are on the back wall behind each rear
seating position. Fold down the rear
seatback to access the anchor. See
instructions for crew cab under Rear Seats
0 25. Be sure to use an anchor located
directly behind the seating position where
the child restraint will be placed.
Extended Cab with Rear Seats
The top tether anchors in an extended cab
model are loops near the top of each rear
seatback. See the instructions under
“Securing a Child Restraint with the LATCH
System” later in this section on how to
attach a top tether.
Do not attach a top tether to the loop near
the top of the seatback of the seating
position in which the child restraint is
installed.Extended Cab without Rear Seats
The top tether anchor in an extended cab
without rear seats is a metal wire on the
lower inboard side of the cab wall directly
behind the front passenger seat.
Do not place heavy objects on the top
tether anchor or use it as a tie down for
cargo as this may cause damage to the
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.

56 Seats and Restraints
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 049 for
additional information.
Securing a Child Restraint with the
LATCH System
{Warning
A child could be seriously injured or killed
in a crash if the child restraint is not
properly attached to the vehicle using
either the LATCH anchors or the vehicle
seat belt. Follow the instructions that
came with the child restraint and the
instructions in this manual.
{Warning
To reduce the risk of serious or fatal
injuries during a crash, do not attach
more than one child restraint to a single
anchor. Attaching more than one child
restraint to a single anchor could cause
(Continued)
Warning (Continued)
the anchor or attachment to come loose
or even break during a crash. A child or
others could be injured.
{Warning
Children can be seriously injured or
strangled if a shoulder belt is wrapped
around their neck. The shoulder belt can
tighten but cannot be loosened if it is
locked. The shoulder belt locks when it is
pulled all the way out of the retractor.
It unlocks when the shoulder belt is
allowed to go all the way back into the
retractor, but it cannot do this if it is
wrapped around a child’s neck. If the
shoulder belt is locked and tightened
around a child’s neck, the only way to
loosen the belt is to cut it.
Buckle any unused seat 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, and
(Continued)
Warning (Continued)
tighten the belt behind the child restraint
after the child restraint has been
installed.
Caution
Do not let the LATCH attachments rub
against the vehicle’s seat belts. This may
damage these parts. If necessary, move
buckled seat belts to avoid rubbing the
LATCH attachments.
Do not fold the rear seatback when the
seat is occupied. Do not fold the empty
rear seat with a seat belt buckled. This
could damage the seat belt or the seat.
Unbuckle and return the seat belt to its
stowed position, before folding the seat.
If you need to secure more than one child
restraint in the rear seat, see Where to Put
the Restraint 049.
