Seats and Restraints 65
{Warning
A child in a rear-facing child restraint can
be seriously injured or killed if the 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 front passenger airbag inflates and
the passenger seat is in a forward
position.
Even if the passenger sensing system has
turned off the 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 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 054 for
additional information. 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. This 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
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 restraint.

15218978) - 2022 - CRC - 5/12/21
66 Seats and Restraints
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 the
combined weight of the child and restraint
are greater than 29.5 kg (65 lb), use the seat
belt with the top tether anchorage only.

See Securing Child Restraints (With the Seat
Belt in the Front Seat) 074 or
Securing Child Restraints (With the Seat Belt
in the Rear Seat) 072. Child restraints built after March 2014 are
labeled with the maximum child weight,
with which the LATCH system can be used
for installing the child 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
Securing Child
Restraints (With the Seat Belt in the Front
Seat) 074 or
Securing Child Restraints (With the Seat Belt
in the Rear Seat) 072.

68 Seats and Restraints
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 the event of 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 a top tether 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 69
To assist in locating the lower anchors, each
second row anchor position has a label, near
the crease between the seatback and the
seat cushion.
The lower anchors are located under the
labeled covers on the seat cushion near the
crease between the seatback and the
seatcushion.
To assist in locating the top tether anchors,
the top tether anchor symbol is near the
top tether anchors.
Top Tether Anchors
For models with a cargo cover, the top
tether anchors are on the back of the rear
seatbacks. Remove the cargo cover before
installing the top tether. The cargo cover
should remain off while the top tether is in use. Be sure to use an anchor directly
behind the seating position where the child
restraint will be placed.
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.
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.
See
Where to Put the Restraint 064 for
additional information.
Securing a Child Restraint Designed for
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.

Buick Envision Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15218978) - 2022 - CRC - 5/12/21
70 Seats and Restraints
{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
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.(Continued)
Warning (Continued)
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
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 064. 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 the top
tether and the seat belt. Refer to the
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, adjust the top tether to its full
length and attach it to the anchor. 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
adjust it accordingly to allow proper
fitment. If you are using a dual
tether, route the tether in between
the headrest or head restraint posts.
.If the position you are using has an
adjustable headrest or head restraint,
adjust it accordingly to allow proper
fitment. If you are using a single
tether, route the tether in between
the headrest or head restraint posts.
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.

72 Seats and Restraints
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,
seeLower Anchors and Tethers for Children
(LATCH System) 065 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) 065 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
064.
1. Put the child restraint on the seat. If the head restraint interferes with the
proper installation of the child restraint,
the head restraint may be removed. See
"Head Restraint Removal and
Reinstallation" under Lower Anchors and
Tethers for Children (LATCH System)
0 65.
2. Pick up the latch plate, and run the lap and shoulder portions of the vehicle seat
belt through or around the child
restraint. The child restraint instructions
will show you how.
3. Push the latch plate into the buckle untilit clicks.
Position the release button on the
buckle, away from the child restraint, so
that the seat belt could be quickly
unbuckled if necessary. The push button
used to release the latch plate must be
visible and not obscured by the child
restraint. There must not be direct
contact of the child restraint to the push
button.
