.There is a critical problem with
the airbag system or the passenger
sensing system.
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 0121.
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(s) to be enabled, the ON
indicator will light and stay lit as a
reminder that the airbag(s) 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 0121 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.
4. Reinstall the child restraint following the directions provided
by the child restraint
manufacturer and refer to
Securing Child Restraints (With the
Seat Belt in the Rear Seat) 092 or
Securing Child Restraints (With the
Seat Belt in the Front Seat) 094.
Make sure the seat belt retractor
is locked by pulling the shoulder
belt all the way out of the
retractor when installing the
child restraint, even if the child
restraint is equipped with a seat
belt lock-off. When the retractor
lock is set, the belt can be
tightened but not pulled out of
the retractor.
5. If, after reinstalling the child restraint and restarting the
vehicle, the ON indicator is still
lit, turn the vehicle off. Then
slightly recline the vehicle
seatback and adjust the seat
cushion, if adjustable, to make

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-13566829) -

74 SEATS AND RESTRAINTS
sure that the vehicle seatback is
not pushing the child restraint
into the seat cushion.
Also make sure the child
restraint is not trapped under the
vehicle head restraint. If this
happens, adjust the head
restraint. SeeHead Restraints
0 44.
6. Restart the vehicle.
The passenger sensing system may or
may not turn off the airbags for a
child in a child restraint depending
upon the child’s size. It is better to
secure the child restraint in a rear
seat. Never put a rear-facing child
restraint in the front seat, even if the
ON indicator is not lit.If the Off Indicator Is Lit for an
Adult-Sized Occupant
If a person of adult size is sitting in
the front outboard passenger seat, but
the OFF indicator is lit, it could be
because that person is not sitting
properly in the seat or that the child
restraint locking feature is engaged.
Use the following steps to allow the
system to detect that person and
enable the front outboard passenger
frontal airbag and knee airbag: 1. Turn the vehicle off. 2. Remove any additional material
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.

SEATS AND RESTRAINTS 75
{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 076 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 put on an unoccupied seat.
If this is not desired remove the object
from the seat.
{Warning
Stowing articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle should
be serviced. There are parts of the
airbag system in several places around
the vehicle. Your dealer and the
service manual have information
about servicing the vehicle and the
airbag system. To purchase a service
manual, see Publication Ordering
Information 0385.
{Warning
For up to 10 seconds after the
vehicle is turned off and the 12‐volt
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the airbag
system. Be sure to follow proper
service procedures, and make sure
the person performing work for you
is qualified to do so.

Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet metal
may keep the airbag system from
working properly.
The operation of the airbag system
can also be affected by changing,
including improperly repairing or
replacing, any parts of the following:
.Airbag system, including airbag
modules, front or side impact
sensors, sensing and diagnostic
module, or airbag wiring
. Front seats, including stitching,
seams or zippers
. Seat belts
. Steering wheel, instrument panel,
overhead console, ceiling trim,
or pillar garnish trim
. Inner door seals, including
speakers Your dealer and the service manual
have information about the location of
the airbag modules and sensors,
sensing and diagnostic module, and
airbag wiring along with the proper
replacement procedures.
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 071. If the vehicle has rollover roof-rail
airbags, see
Different Size Tires and
Wheels 0333 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 0378.
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 0121.
