.The system determines that 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.
. 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 0126.
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 safety 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 0126 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
Safety Belt in the Rear Seat) 098
or Securing Child Restraints (With
the Safety Belt in the Front
Seat) 099.
Make sure the safety 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
safety belt lock-off. When the

Cadillac CT6 Owner Manual (GMNA-Localizing-MidEast-10293390) - 2017 -

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
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. See Head
Restraints 056.
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 83
{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
Safety 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“Safety Belts” and“Child
Restraints ”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 084 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 of 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.
{Warning
For up to 10 seconds after the
vehicle is turned off and the 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 any parts of the front seats,
safety belts, the airbag sensing and
diagnostic module, steering wheel,
instrument panel, any of the airbag
modules, ceiling or pillar garnish trim,
front sensors, side impact sensors,
or airbag wiring.
Your dealer and the service manual
have information about the location of
the airbag sensors, sensing and
diagnostic module, and airbag wiring.
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. Anyobject, 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 079.
The vehicle has rollover roof-rail
airbags. See Different Size Tires and
Wheels 0288 for additional important
information.
If your vehicle needs to be modified
because you have a disability and you
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, see
your dealer.
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 0126.
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? 075. See
your dealer for service.

{Warning
Heater and radiator hoses, and
other engine parts, can be very hot.
Do not touch them. If you do, you
can be burned.
Do not run the engine if there is a
leak. If you run the engine, it could
lose all coolant. That could cause
an engine fire, and you could be
burned. Get any leak fixed before
you drive the vehicle.
Caution
Using coolant other than
DEX-COOL®can cause premature
engine, heater core, or radiator
corrosion. In addition, the engine
coolant could require changing
sooner. Any repairs would not be
covered by the vehicle warranty.
Always use DEX-COOL (silicate-free)
coolant in the vehicle.
Engine Coolant
The cooling system in the vehicle is
filled with DEX-COOL®engine coolant.
This coolant needs to be checked and
replaced at appropriate intervals. See
