78 Seats and Restraints
Booster Seats
A belt-positioning booster
seat is used for children who
have outgrown their
forward-facing child restraint.
Boosters are designed to
improve the fit of the vehicle's
seat belt system until the child
is large enough for the vehicle
seat belts to fit properly
without a booster seat. See
the seat belt fit test in Older
Children 073.
Securing an Add-On Child
Restraint in the Vehicle
{Warning
A child can be seriously
injured or killed in a crash if
the child restraint is not
properly secured in the
vehicle. Secure the child
restraint properly in the
vehicle using the vehicle
seat belt or LATCH system,
following the instructions
that came with that child
restraint and the
instructions in this manual.
To help reduce the chance of
injury, the child restraint must
be secured in the vehicle. Child
restraints must be secured in
vehicle seats by lap belts or
the lap belt portion of a
lap-shoulder belt, or by the
LATCH system. See Lower
Anchors and Tethers for
Children (LATCH System) 080
for more information. Never
use a seat belt extender when installing a child restraint.
Never use non-regulated
aftermarket anchors or
attachments to secure a child
restraint. Children can be
endangered in a crash if the
child restraint is not properly
secured in the vehicle.
When securing an add-on child
restraint, refer to the
following:
1. Instruction labels provided on the child restraint
2. Instruction manual provided with the child restraint
3. This vehicle owner's manual
The child restraint instructions
are important, so if they are
not available, obtain a
replacement copy from the
manufacturer.
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

Seats and Restraints 79
properly secure any child
restraint in the vehicle—even
when no child is in it.
In some areas Certified Child
Passenger Safety Technicians
(CPSTs) are available to
inspect and demonstrate how
to correctly use and install
child restraints. In the U.S.,
refer to the National Highway
Traffic Safety Administration
(NHTSA) website to locate the
nearest child safety seat
inspection station. For CPST
availability in Canada, check
with Transport Canada or the
Provincial Ministry of
Transportation office.
Securing the Child Within

Warning (Continued)
properly following the
instructions that came with
that child restraint.
Where to Put the
Restraint
According to accident
statistics, children and infants
are safer when properly
restrained in an appropriate
child restraint secured in a
rear seating position.
Whenever possible, children
aged 12 and under should be
secured in a rear seating
position.
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.
{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.(Continued)

80 Seats and Restraints
Warning (Continued)
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.
See Passenger Sensing
System066 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.

Cadillac Lyriq Owner Manual (GMNA-Localizing-U.S./Canada-15644413) -
2023 - CRC - 2/23/22
Seats and Restraints 81
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.
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 bedone 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.

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

Seats and Restraints 83
be used (with top tether
where available) to secure the
child restraint. See Securing
Child Restraints (With the
Seat Belt in the Front Seat)
090 or
Securing Child Restraints
(With the Seat Belt in the Rear
Seat) 088.
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 androtation 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 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.

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 Restraint079 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.
{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)

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.
