Why Seat Belts Work
When riding in a vehicle, you
travel as fast as the vehicle
does. If the vehicle stops
suddenly, you keep going until
something stops you. It could
be the windshield, the
instrument panel, or the seat
belts!
When you wear a seat belt,
you and the vehicle slow down
together. There is more time
to stop because you stop over
a longer distance and, when
worn properly, your strongest
bones take the forces fromthe seat belts. That is why
wearing seat belts makes such
good sense.
Questions and Answers
About Seat Belts
Q: Will I be trapped in the
vehicle after a crash if I am
wearing a seat belt?
A: You could be —whether you
are wearing a seat belt or
not. Your chance of being
conscious during and after a
crash, so you can unbuckle
and get out, is much greater
if you are belted.
Q: If my vehicle has airbags, why should I have to wear
seat belts?
A: Airbags are supplemental
systems only. They work
with seat belts —not
instead of them. Whether or
not an airbag is provided, all
occupants still have to
buckle up to get the most
protection. Also, in nearly all states and
in all Canadian provinces,
the law requires wearing
seat belts.
Buckle To Drive
If equipped, this feature delays
the vehicle from shifting out of
P (Park) when the driver seat
belt is not buckled. The Buckle
to Drive feature must be
turned ON in the infotainment
system to work. To turn the
Buckle to Drive feature on or
off, select Settings > Vehicle >
Buckle to Drive. See Teen
Driver
0211, if equipped.
If the vehicle is on and the
brake pedal is pressed with
the vehicle in P (Park) but the
driver seat belt is not buckled,
a message displays in the
Driver Information Center (DIC)
and the vehicle will be delayed
from shifting out of P (Park).
Buckle the driver seat belt to
clear the message and shift
out of P (Park). Shifting from

Seats and Restraints 51
P (Park) will be delayed once
for each time the vehicle is
started.
For some fleet vehicles, the
feature is always ON and
cannot be turned OFF in the
infotainment system. The
vehicle will be delayed from
shifting from P (Park) each
time the driver attempts to do
so while the driver seat belt is
not buckled. Turning the
vehicle off then on will not
change this condition.
On some models, Buckle to
Drive may also delay shifting
out of P (Park) if a front
passenger seat belt is
unbuckled. A message displays
in the DIC. Buckle the front
passenger seat belt to shift
out of P (Park). This feature
may delay the vehicle from
shifting out of P (Park) if an
object, such as a briefcase,
handbag, grocery bag, laptop,
or other electronic device, is
on the front passenger seat.
If this happens, remove theobject from the seat or buckle
the seat belt to shift out of
P (Park).
If the driver, or on some
vehicles, the present front
passenger remains unbuckled,
the DIC message will turn off
after several seconds and the
vehicle can be shifted out of
P (Park). See
“Seat Belts”and
“Child Restraints” in the Index
for information about the
importance of proper
restraint use.
If the driver seat belt or the
front passenger seat belt is
unbuckled when driving, the
seat belt reminder chime and
light(s) will come on. See Seat
Belt Reminders 0115. This
feature may not function
properly if the airbag
readiness light is on. See
Airbag Readiness Light 0116.How to Wear Seat
Belts Properly
Follow these rules for
everyone's protection.
There are additional things to
know about seat belts and
children, including smaller
children and infants. If a child
will be riding in the vehicle, see
Older Children 072 or
Infants and Young Children
0 74. Review and follow the
rules for children in addition to
the following rules.
It is very important for all
occupants to buckle up.
Statistics show that unbelted
people are hurt more often in
crashes than those who are
wearing seat belts.

52 Seats and Restraints
.Sit up straight and always
keep your feet on the floor in
front of you (if possible).
.Wear the lap part of the belt
low and snug on the hips,
just touching the thighs. In a
crash, this applies force to
the strong pelvic bones and
you would be less likely to
slide under the lap belt.
If you slid under it, the belt
would apply force on your
abdomen. This could cause
serious or even fatal injuries.
.Wear the shoulder belt over
the shoulder and across the
chest. These parts of the
body are best able to take
belt restraining forces. The
shoulder belt locks if there is
a sudden stop or crash.
{Warning
You can be seriously injured,
or even killed, by not
wearing your seat belt
properly.
Never allow the lap or
shoulder belt to become loose
or twisted.

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-16500442) -
2023 - CRC - 5/4/22
Seats and Restraints 53
Never wear the shoulder belt
under both arms or behind
your back.
Always use the correct buckle
for your seating position.
Never route the lap or
shoulder belt over an armrest.
{Warning
The seat belt can be pinched
if it is routed under plastic
trim on the seat, such as
trim around the rear
seatback folding handle or
side airbag. In a crash,
pinched seat belts might not
provide adequate(Continued)
Warning (Continued)
protection. Never allow seat
belts to be routed under
plastic trim pieces.
{Warning
You can be seriously injured
or killed if the shoulder belt
is worn behind your back,
under your legs, or wrapped
around your 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 you. You
may have to cut the seat
belt if it is locked and
tightened around you.

54 Seats and Restraints
Lap-Shoulder Belt
All seating positions in the
vehicle have a
lap-shoulder belt.
If you are using a rear seating
position with a detachable
seat belt and the seat belt is
not attached, see Rear Seats
047 for instructions on
reconnecting the seat belt to
the mini-buckle.
The following instructions
explain how to wear a
lap-shoulder belt properly.
1. If the seat has a seat belt guide, the seat belt must
be routed through the
guide to properly position
the shoulder belt. If the
seat belt is not routed
through the guide, slide
the edge of the belt
webbing through the
opening on the guide. Be
sure the belt is not twisted. 2. Adjust the seat, if the seat
is adjustable, so you can sit
up straight. To see how,
see “Seats” in the Index.
3. Pick up the latch plate and
pull the belt across you. Do
not let it get twisted.
The lap-shoulder belt may
lock if you pull the belt
across you very quickly.
If this happens, let the belt
go back slightly to unlock
it. Then pull the belt across
you more slowly. If the shoulder portion of a
passenger belt is pulled
out all the way, the child
restraint locking feature
may be engaged. See Child
Restraint Systems
077.
If this occurs, let the belt
go back all the way and
start again. If the locking
feature stays engaged
after letting the belt go
back to stowed position on
the seat, move the seat
rearward or recline the
seat until the shoulder belt
retractor lock releases.
Engaging the child
restraint locking feature in
the front outboard seating
position may affect the
passenger sensing system.
See Passenger Sensing
System 066.
If the shoulder portion of
the driver belt is pulled out
all the way, the shoulder
belt retractor lock feature
may be engaged. If this
happens, let the belt go
back all the way and start

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-16500442) -

Seats and Restraints 55
again. If the locking feature
stays engaged after letting
the belt go back to stowed
position on the seat, move
the seat rearward or
recline the seat until the
shoulder belt retractor
lock releases.
If the webbing locks in the
latch plate before it
reaches the buckle, tilt the
latch plate flat to unlock.
4. Push the latch plate intothe buckle until it clicks.
Pull up on the latch plate
to make sure it is secure.
If the belt is not long
enough, see Seat Belt
Extender 057.
Position the release button
on the buckle so that the
seat belt could be quickly
unbuckled if necessary.5. To make the lap part tight, pull up on the
shoulder belt.
It may be necessary to pull
the webbing firmly,
through the adjustable
stop, or move the
adjustable stop along the
webbing toward the
outboard floor anchor, to
fully tighten the lap belt
across the lap.

56 Seats and Restraints
To unlatch the belt, push the
button on the buckle. The belt
should return to its stowed
position.
Slide the adjustable stop along
the webbing toward the guide
loop when the seat belt is not
in use to prevent the latch
plate from rattling against the
interior trim.
Always stow the seat belt
slowly. If the seat belt webbing
returns quickly to the stowed
position, the retractor may
lock and cannot be pulled out.
If this happens, pull the seat
belt straight out firmly tounlock the webbing, and then
release it. If the webbing is still
locked in the retractor, see
your dealer.
Before a door is closed, be
sure the seat belt is out of the
way. If a door is slammed
against a seat belt, damage
can occur to both the seat
belt and the vehicle.
Seat Belt Pretensioners
This vehicle has seat belt
pretensioners for the front
outboard occupants. Although
the seat belt pretensioners
cannot be seen, they are part
of the seat belt assembly.
They can help tighten the seat
belts during the early stages
of a moderate to severe
frontal, near frontal, or rear
crash if the threshold
conditions for pretensioner
activation are met. Seat belt
pretensioners can also help
tighten the seat belts in a side
crash or a rollover event.
Pretensioners work only once.
If the pretensioners activate in
a crash, the pretensioners and
probably other parts of the
vehicle's seat belt system will
need to be replaced. See
Replacing Seat Belt System
Parts after a Crash
058.
Do not sit on the outboard
seat belt while entering or
exiting the vehicle or at any
time while sitting in the seat.
Sitting on the seat belt can
damage the webbing and
hardware.
Rear Seat Belt Comfort
Guides
Rear seat belt comfort guides
may provide added seat belt
comfort for older children who
have outgrown booster seats
and for some adults. When
installed on a shoulder belt,
the comfort guide positions
the shoulder belt away from
the neck and head.

Comfort guides are available
through your dealer for the
rear outboard seating
positions. Instructions are
included with the guides.
Seat Belt Use During
Pregnancy
Seat belts work for everyone,
including pregnant women.
Like all occupants, they are
more likely to be seriously
injured if they do not wear
seat belts.
A pregnant woman should
wear a lap-shoulder belt, and
the lap portion should be worn
as low as possible, below the
rounding, throughout the
pregnancy.
The best way to protect the
fetus is to protect the mother.
When a seat belt is worn
properly, it is more likely that
the fetus will not be hurt in a
crash. For pregnant women, as
for anyone, the key to making
seat belts effective is wearing
them properly.
Seat Belt Extender
If the vehicle's seat belt will
fasten around you, you should
use it.
But if a seat belt is not long
enough, your dealer will order
you an extender. Only a GM
dealer issued extender should
be used. When you go in to
order it, take the heaviest coat
you will wear, so the extender
will be long enough for you. To
help avoid personal injury, donot let someone else use it,
and use it only for the seat it is
made to fit. The extender has
been designed for adults.
Never use it for securing child
restraints. For more
information on the proper use
and fit of seat belt extenders
see the instruction sheet that
comes with the extender.
Safety System Check
Periodically check the seat
belt reminder, seat belts,
buckles, latch plates,
retractors, shoulder belt
height adjusters (if equipped),
and seat belt anchorages to
make sure they are all in
working order. Look for any
other loose or damaged seat
belt system parts that might
keep a seat belt system from
performing properly. See your
dealer to have it repaired.
Torn, frayed, or twisted seat
belts may not protect you in a
crash. Torn or frayed seat
belts can rip apart under
impact forces. If a belt is torn

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-16500442) -
2023 - CRC - 5/4/22
58 Seats and Restraints
or frayed, have it replaced
immediately. If a belt is
twisted, it may be possible to
untwist by reversing the latch
plate on the webbing. If the
twist cannot be corrected, ask
your dealer to fix it.
Make sure the seat belt
reminder light is working. See
Seat Belt Reminders0115.
Keep seat belts clean and dry.
See Seat Belt Care 058.
Seat Belt Care
Keep belts clean and dry.
Seat belts should be properly
cared for and maintained.
Seat belt hardware should be
kept dry and free of dust or
debris. As necessary, exterior
hard surfaces and seat belt
webbing may be lightly
cleaned with mild soap and
water. Ensure there is not
excessive dust or debris in the
mechanism. If dust or debris
exists in the system please
see the dealer. Parts may need to be replaced to ensure
proper functionality of the
system.
{Warning
Do not bleach or dye seat
belt webbing. It may severely
weaken the webbing. In a
crash, they might not be
able to provide adequate
protection. Clean and rinse
seat belt webbing only with
mild soap and lukewarm
water. Allow the webbing
to dry.
Replacing Seat Belt
System Parts after a
Crash
{Warning
A crash can damage the
seat belt system in the
vehicle. A damaged seat belt
system may not properly
protect the person using it,
(Continued)
Warning (Continued)
resulting in serious injury or
even death in a crash. To
help make sure the seat belt
systems are working
properly after a crash, have
them inspected and any
necessary replacements
made as soon as possible.
After a minor crash,
replacement of seat belts may
not be necessary. But the seat
belt assemblies that were
used during any crash may
have been stressed or
damaged. See your dealer to
have the seat belt assemblies
inspected or replaced.
New parts and repairs may be
necessary even if the seat belt
system was not being used at
the time of the crash.
Have the seat belt
pretensioners checked if the
vehicle has been in a crash,
or if the airbag readiness light
stays on after you start the

driving. See Airbag Readiness
Light0116.
Airbag System
The vehicle has the following
airbags:
.A frontal airbag for the
driver
.A frontal airbag for the front
outboard passenger
.A knee airbag for the driver.
.A knee airbag for the front
outboard passenger.
.A seat-mounted side impact
airbag for the driver
.A seat-mounted side impact
airbag for the front outboard
passenger
.A roof-rail airbag for the
driver and the passenger
seated directly behind the
driver
.A roof-rail airbag for the
front outboard passenger
and the passenger seated
directly behind the front
outboard passenger All vehicle airbags have the
word AIRBAG on the trim or
on a label near the deployment
opening.
For frontal airbags, the word
AIRBAG is on the center of the
steering wheel for the driver
and on the instrument panel
for the front outboard
passenger.
For knee airbags, the word
AIRBAG is on the lower part of
the instrument panel.
For seat-mounted side impact
airbags, the word AIRBAG is
on the side of the seatback or
side of the seat closest to
the door.
For roof-rail airbags, the word
AIRBAG is on the ceiling
or trim.
Airbags are designed to
supplement the protection
provided by seat belts. Even
though today's airbags are
also designed to help reduce
the risk of injury from the
force of an inflating bag, all
airbags must inflate very
quickly to do their job.
Here are the most important
things to know about the
airbag system:
{Warning
You can be severely injured
or killed in a crash if you are
not wearing your seat belt,
even with airbags. Airbags
are designed to work with
seat belts, not replace them.
Also, airbags are not
designed to inflate in every
crash. In some crashes seat
belts are the only restraint.
See When Should an Airbag
Inflate?

Wearing your seat belt
during a crash helps reduce
your chance of hitting things
inside the vehicle or being
ejected from it. Airbags are
