SEATS AND RESTRAINTS 41
Warning (Continued)
Always wear a seat belt, and check
that all passenger(s) are restrained
properly too.
This vehicle has indicators as a
reminder to buckle the seat belts. See
Seat Belt Reminders 097.
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 from the 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 withseat 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 prevents 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. See
Vehicle Personalization
0120 and if
equipped, Teen Driver 0189. If the
engine is running, the driver seat belt
is not buckled, and the brake pedal is
pressed with the vehicle in P (Park), a
message displays in the Driver
Information Center (DIC). Buckle the
driver seat belt to shift out of P (Park).
Shifting from P (Park) will be
prevented once for each ignition cycle.
For some fleet vehicles, the feature is
always ON and it cannot be turned
OFF in the infotainment system.
Shifting from P (Park) will be
prevented each time the above
conditions exist.

42 SEATS AND RESTRAINTS
On some models, Buckle to Drive may
also prevent shifting out of P (Park) if
a front passenger is unbuckled under
similar conditions. A message displays
in the DIC. Buckle the front passenger
seat belt to shift out of P (Park). This
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 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 097. This feature may not function properly if the airbag
readiness light is on. See
Airbag
Readiness Light 098.
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 060 or
Infants and Young Children 061.
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).
.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.

44 SEATS AND RESTRAINTS
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
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.
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.

48 SEATS AND RESTRAINTS
seat belts can rip apart under impact
forces. If a belt is torn 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. SeeSeat Belt Reminders
0 97.
Keep seat belts clean and dry. See Seat
Belt Care 048.
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. 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 vehicle or
while you are driving. See
Airbag
Readiness Light 098.
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
Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-15283641) -

SEATS AND RESTRAINTS 49
.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? 051.
Wearing your seat belt during a
crash helps reduce your chance of
hitting things inside the vehicle or
being ejected from it. Airbags are
“supplemental restraints” to the
seat belts. Everyone in the vehicle (Continued)
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.

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 060 or
Infants and Young Children 061.
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 098.
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 driver knee airbag is below the
steering column. The front outboard
passenger knee airbag is below the
glove box.
