The feature is active only once each
time the vehicle is turned on and off,
and will require reactivation by
opening and closing the second row
doors. There may be an alert even
when there is nothing in the rear seat;
for example, if a child entered the
vehicle through the rear door and left
the vehicle without the vehicle being
shut off.
The feature can be turned on or off.
SeeVehicle Personalization 0117.
Folding the Seatback
Either side of the seatback can be
folded for more cargo space. Fold a
seatback only when the vehicle is not
moving.
Caution

feature may not allow the vehicle to
shift 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 the object 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, and in some
vehicles the front passenger seat belt,
is unbuckled when driving, the seat
belt reminder chime and light(s) will
come on. See Seat Belt Reminders 095.
This feature may not function
properly if the airbag readiness light is
on. See Airbag Readiness Light 096.
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 059 or
Infants and Young Children 060.
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.
There are important things to know
about wearing a seat belt properly.
.Sit up straight and always keep your
feet on the floor in front of you (if
possible).
.Always use the correct buckle for
your seating position.
.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.

44 SEATS AND RESTRAINTS
{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 be able to provide
adequate protection. Never allow
seat belts to be routed under plastic
trim pieces.
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, seeRear
Seats 038 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 063. 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 053.

firmly to unlock 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 systemwill need to be replaced. See
Replacing
Seat Belt System Parts after a Crash
0 47.
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.

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-14584335) -
2021 - CRC - 11/23/20
SEATS AND RESTRAINTS 47
But if a seat belt is not long enough,
your dealer will order you an extender.
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, do not
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 or frayed, haveit 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 Reminders
0 95.
Keep seat belts clean and dry. See Seat
Belt Care 047.
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,
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.

Warning (Continued)
should wear a seat belt properly,
whether or not there is an airbag
for that person.
{Warning
Because airbags inflate with great
force and faster than the blink of an
eye, anyone who is up against,
or very close to, any airbag when it
inflates can be seriously injured or
killed. Do not sit unnecessarily
close to any airbag, as you would be
if sitting on the edge of the seat or
leaning forward. Seat belts help
keep you in position before and
during a crash. Always wear a seat
belt, even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle. The seat belts and the
front outboard passenger airbags
are most effective when you are
sitting well back and upright in the
seat with both feet on the floor.(Continued)
Warning (Continued)
Occupants should not lean on or
sleep against the door or side
windows in seating positions with
seat-mounted side impact airbags
and/or roof-rail airbags.
{Warning
Children who are up against,
or very close to, any airbag when it
inflates can be seriously injured or
killed. Always secure children
properly in the vehicle. To read
how, seeOlder Children 059 or
Infants and Young Children 060.
There is an airbag readiness light on
the instrument cluster, which shows
the airbag symbol. The system checks the airbag
electrical system for malfunctions.
The light tells you if there is an
electrical problem. See
Airbag
Readiness Light 096.
Where Are the Airbags?
The driver frontal airbag is in the
center of the steering wheel.
The front outboard passenger frontal
airbag is in the passenger side
instrument panel.

The words ON and OFF, and the
symbols for on and off, will be visible
during the system check. When the
system check is complete, either the
word ON or OFF, and the symbol for
on or off, will be visible. SeePassenger
Airbag Status Indicator 096.
The passenger sensing system turns
off the front outboard passenger
frontal airbag and knee airbag under
certain conditions. No other airbag is
affected by the passenger sensing
system.
The passenger sensing system works
with sensors that are part of the front
outboard passenger seat and seat belt.
The sensors are designed to detect the
presence of a properly seated
occupant and determine if the front
outboard passenger frontal airbag and
knee airbag should be allowed to
inflate or not. According to accident statistics,
children are safer when properly
secured in a rear seat in the correct
child restraint for their weight
and size.
Whenever possible, children aged
12 and under should be secured in a
rear seating position.
Never put a rear-facing child seat in
the front. This is because the risk to
the rear-facing child is so great, if the
airbag inflates.
{Warning
A child in a rear-facing child
restraint can be seriously injured or
killed if the 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 passenger frontal airbag
inflates and the passenger seat is in
a forward position.
(Continued)
Warning (Continued)
Even if the passenger sensing
system has turned off the front
outboard passenger airbag(s), no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though the
airbag(s) are off.
Never put a rear-facing child
restraint in the front seat, even if
the airbag is off. If securing a
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 child
restraints in the rear seat. Consider
using another vehicle to transport
the child when a rear seat is not
available.
