Replacing LATCH System
Parts After a Crash
{ WarningA 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
(With the Seat Belt in the
Rear Seat) 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.
If the child restraint has the LATCH
system, see Lower Anchors and
Tethers for Children (LATCH
System) 0 106 for how and where to
install the child restraint using
LATCH. If a child restraint is secured
in the vehicle using a seat belt and
it uses a top tether, see Lower
Anchors and Tethers for Children
(LATCH System) 0 106 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 tether
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 or vehicle seat
position does not have the LATCH
system, you will be using the seat
belt to secure the child restraint. Be
sure to follow the instructions that
came with the child restraint.
If more than one child restraint
needs to be installed in the rear
seat, be sure to read Where to Put
the Restraint 0 104 .
Double Cab 1. Remove the head restraint or
headrest prior to installing a
forward-facing child restraint in
an outboard rear seating
position. See “ Head Restraint
or Headrest Removal and
Reinstallation ” under Lower
Anchors and Tethers for
Children (LATCH System)
0 106 .
2. Put the child restraint on
the seat.

the lap and shoulder portions
of the vehicle's seat belt
through or around the child
restraint. The child restraint

the retractor. 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. 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.
Try to pull the belt out of the
retractor to make sure the
retractor is locked. If the
retractor is not locked, repeat
Steps 5 and 6.

child restraint is properly
installed, there should be no
more than 2.5 cm (1 in) of
movement.
To remove the child restraint,
unbuckle the vehicle seat belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it.
Reinstall the head restraint or
headrest before the seating position
is used. See “ Head Restraint or Headrest Removal and
Reinstallation ” under Lower Anchors
and Tethers for Children (LATCH
System) 0 106 for additional
information on installing the
headrest properly.

Securing Child Restraints
(In the Center Front Seat)
{ WarningA 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.

GMC Sierra/Sierra Denali Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-1500-11698638) - 2019 - crc - 5/15/18
Seats and Restraints 121Do not use child restraints in the
center front seat position.
Securing Child Restraints
(With the Seat Belt in the
Front Outboard Seat) This vehicle has airbags. A rear
seat is a safer place to secure a
forward-facing child restraint. See
Where to Put the Restraint 0 104 .
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the front
outboard passenger frontal airbag
under certain conditions.
See Passenger Sensing System
0 92 and Passenger Airbag Status
Indicator 0 148 for more information,
including important safety
information.
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. { WarningA child in a rear-facing child
restraint can be seriously injured
or killed if the front outboard
passenger frontal 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 front
outboard passenger frontal airbag
inflates and the passenger seat is
in a forward position.
Even if the passenger sensing
system has turned off the front
outboard 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
(Continued) Warning (Continued) forward-facing child restraint in
the front outboard passenger
seat, always move the seat as far
back as it will go. It is better to
secure the child restraint in a
rear seat.
See Passenger Sensing System
0 92 for additional information.
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 installed in the vehicle, even if
the airbag is off.
If the child restraint uses a top
tether, see Lower Anchors and
Tethers for Children (LATCH
System) 0 106 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

122 Seats and Restraints the instructions that come with the
child restraint say that the top tether
must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached.
When using the lap-shoulder belt to
secure the child restraint in this
position, follow the instructions that
came with the child restraint and the
following instructions:
1. Move the seat as far back as it
will go before securing the
forward-facing child restraint.
Move the seat upward or the
seatback to an upright position,
if needed, to get a tight
installation of the child
restraint.
When the passenger sensing
system has turned off the front
outboard passenger frontal
airbag, the OFF indicator on
the passenger airbag status
indicator should light and stay lit when you start the vehicle.
See Passenger Airbag Status
Indicator 0 148 .
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 seat belt
through or around the child
restraint. The child restraint
instructions will show you how.
Tilt the latch plate to adjust the
belt if needed. 4. Push the latch plate into the
buckle until it clicks.
Position the release button on
the buckle, away from the child
restraint, so that the seat belt
could be quickly unbuckled if
necessary.

attach the top tether to the top
tether anchor. Refer to the
