especially for long periods of
time. Do not place anything
on the seat that insulates
against heat, such as a
blanket, cushion, cover,
or similar item. This may
cause the seat heater to

74 Seats and Restraints
.The system determines an
infant is present in a child
restraint.
.A front outboard passenger
takes his/her weight off of
the seat for a period of time.
When the passenger sensing
system has turned off the
front outboard passenger
frontal airbag and knee airbag,
the OFF indicator will light and
stay lit as a reminder that the
airbags are off. See Passenger
Airbag Status Indicator 0124.
The passenger sensing
system is designed to turn on
the front outboard passenger
frontal airbag and knee airbag,
anytime the system senses
that a person of adult size is
sitting properly in the front
outboard passenger seat.
When the passenger sensing
system has allowed the airbag
to be enabled, the ON
indicator will light and stay lit
as a reminder that the airbags
are active. For some children, including
children in child restraints, and
for very small adults, the
passenger sensing system
may or may not turn off the
front outboard passenger
frontal airbag and knee airbag,
depending upon the person's
seating posture and body
build. Everyone in the vehicle
who has outgrown child
restraints should wear a seat
belt properly
—whether or not
there is an airbag for that
person.
{Warning
If the airbag readiness light
ever comes on and stays on,
it means that something may
be wrong with the airbag
system. To help avoid injury
to yourself or others, have
the vehicle serviced right
away. See Airbag Readiness
Light 0123 for more
information, including
important safety
information.
If the On Indicator Is Lit
for a Child Restraint
The passenger sensing
system is designed to turn off
the front outboard passenger
frontal airbag and knee airbag,
if the system determines that
an infant is present in a child
restraint. If a child restraint
has been installed and the ON
indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such
as blankets, cushions, seat
covers, seat heaters,
or seat massagers.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -

76 Seats and Restraints
1. Turn the vehicle off.
2. Remove any additionalmaterial from the seat,
such as blankets, cushions,
seat covers, seat heaters,
or seat massagers.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat,
centered on the seat
cushion, with legs
comfortably extended.
5. If the shoulder portion of the belt is pulled out all the
way, the child restraint
locking feature will be
engaged. This may
unintentionally cause the
passenger sensing system
to turn the airbag off for
some adult-sized
occupants. If this happens,
unbuckle the belt, let the
belt go back all the way,
and then buckle the belt
again without pulling the
belt out all the way. 6. Restart the vehicle and
have the person remain in
this position for two to
three minutes after the ON
indicator is lit.
{Warning
If the front outboard
passenger airbag is turned
off for an adult-sized
occupant, the airbag will not
be able to inflate and help
protect that person in a
crash, resulting in an
increased risk of serious
injury or even death. An
adult-sized occupant should
not ride in the front
outboard passenger seat,
if the passenger airbag OFF
indicator is lit.
Additional Factors
Affecting System
Operation
Seat belts help keep the
passenger in position on the
seat during vehicle maneuvers and braking, which helps the
passenger sensing system
maintain the passenger airbag
status. See
“Seat Belts” and
“Child Restraints” in the Index
for additional information
about the importance of
proper restraint use.
A thick layer of additional
material, such as a blanket or
cushion, or aftermarket
equipment such as seat
covers, seat heaters, and seat
massagers can affect how well
the passenger sensing system
operates. We recommend that
you not use seat covers or
other aftermarket equipment
except when approved by GM
for your specific vehicle. See
Adding Equipment to the
Airbag-Equipped Vehicle 077
for more information about
modifications that can affect
how the system operates.
The ON indicator may be lit if
an object, such as a briefcase,
handbag, grocery bag, laptop,
or other electronic device, is

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/6/22
78 Seats and Restraints
In addition, the vehicle has a
passenger sensing system for
the front outboard passenger
position, which includes
sensors that are part of the
passenger seat. The
passenger sensing system
may not operate properly if
the original seat trim is
replaced with non-GM covers,
upholstery, or trim; or with GM
covers, upholstery, or trim
designed for a different
vehicle. Any object, such as an
aftermarket seat heater or a
comfort-enhancing pad or
device, installed under or on
top of the seat fabric, could
also interfere with the
operation of the passenger
sensing system. This could
either prevent proper
deployment of the passenger
airbag(s) or prevent the
passenger sensing system
from properly turning off the
passenger airbag(s). See
Passenger Sensing System
072. If the vehicle has rollover
roof-rail airbags, see Different
Size Tires and Wheels
0439
for additional important
information.
If the vehicle must be modified
because you have a disability
and have questions about
whether the modifications will
affect the vehicle's airbag
system, or if you have
questions about whether the
airbag system will be affected
if the vehicle is modified for
any other reason, call
Customer Assistance. See
Customer Assistance Offices
0 487.
Airbag System Check
The airbag system does not
need regularly scheduled
maintenance or replacement.
Make sure the airbag
readiness light is working. See
Airbag Readiness Light 0123.
Caution
If an airbag covering is
damaged, opened, or broken,
the airbag may not work
properly. Do not open or
break the airbag coverings.
If there are any opened or
broken airbag coverings,
have the airbag covering
and/or airbag module
replaced. For the location of
the airbags, see Where Are
the Airbags? 067. See your
dealer for service.

394 Vehicle Care
Engine Coolant
The cooling system in the
vehicle is filled with
DEX-COOL engine coolant.
See Maintenance Schedule
0471 and
Recommended Fluids and
Lubricants 0476.
The following explains the
cooling system and how to
check and add coolant when it
is low. If there is a problem
with engine overheating, see
Engine Overheating 0398.
What to Use
{Warning
Do not touch heater or
radiator hoses, or other
engine parts. They can be
very hot and can burn you.
Do not run the engine if
there is a leak; all coolant
could leak out. That could
cause an engine fire and can
burn you. Fix any leak before
driving the vehicle. Use a 50/50 mixture of clean
drinkable water and
DEX-COOL coolant. This
mixture:
.Gives freezing protection
down to
−37 °C (−34 °F),
outside temperature.
.Gives boiling protection up
to 129 °C (265 °F), engine
temperature.
.Protects against rust and
corrosion.
.Will not damage aluminum
parts.
.Helps keep the proper
engine temperature.
Caution
Do not use anything other
than a mix of DEX-COOL
coolant that meets GM
Standard GMW3420 and
clean, drinkable water.
Anything else can cause
damage to the engine
cooling system and the

Caution (Continued)
vehicle, which would not be
covered by the vehicle
warranty.
Never dispose of engine
coolant by putting it in the
trash, pouring it on the
ground, or into sewers,
streams, or bodies of water.
Have the coolant changed by
an authorized service center,
familiar with legal
requirements regarding used
coolant disposal. This will help
protect the environment and
your health.
Checking Coolant
The vehicle must be on a level
surface when checking the
