Seats and Restraints 87
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 installed using
only the top tether and
anchor.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 Rear
Seat) 095 or
Securing Child Restraints
(With the Seat Belt in the
Front Seat) 098. 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 Rear Seat)
095 or
Securing Child Restraints
(With the Seat Belt in the
Front Seat) 098.
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.

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
Seats and Restraints 91
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 Restraint085 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)

92 Seats and Restraints
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(Continued)
Caution (Continued)
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 085.
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.
For rear outboard
seating positions, 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” at the
end of this section.
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.

route the tether
around the headrest or
head restraint posts.
If the child restraint is
installed next to a
center seat, make sure
the top tether does not
interfere with the
center seating position
shoulder belt/retractor.
If it does, find another
suitable seating
position to install the
child 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.Head Restraint Removal
and Reinstallation
The second row outboard
head restraints can be
removed if they interfere with
the proper installation of the
child restraint.
To remove the second row
head restraint:
1. Partially fold the seatback forward. See Rear Seats
055 for additional
information.
2. Press both buttons on the head restraint posts at the
same time, and pull up on
the head restraint.
3. Store the head restraint in a secure place.
4. When the child restraint is removed, reinstall the head
restraint before the
seating position is used.
{Warning
With head restraints that
are not installed and
adjusted properly, there is a
greater chance that
occupants will suffer a neck/
spinal injury in a crash. Do
not drive until the head
restraints for all occupants
are installed and adjusted
properly.

See Head Restraints 045.
3. Try to move the head restraint to make sure that
it is locked in place.
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 (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) 086
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) 086 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
085.
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)
086.
2. Pick up the latch plate and run the lap and shoulder
portions of the vehicle
seat belt through or
around the child restraint.
Ensure the seat belt
webbing is routed as
directly as possible and is
not caught on seat handles
or plastic trim. The child
restraint instructions will
show you how.
3. Push the latch plate intothe 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.
There must not be direct
contact of the child
restraint to the push
button.
