{Warning
When an airbag inflates, there may
be dust in the air. This dust could
cause breathing problems for
people with a history of asthma or
other breathing trouble. To avoid
this, everyone in the vehicle should
get out as soon as it is safe to do
so. If you have breathing problems
but cannot get out of the vehicle
after an airbag inflates, then get
fresh air by opening a window or a
door. If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers, and shut off the fuel
system after the airbags inflate. The
feature may also activate, without
airbag inflation, after an event that
exceeds a predetermined threshold.
You can lock the doors, turn off the interior lamps, and turn off the hazard
warning flashers by using the controls
for those features.
{Warning
A crash severe enough to inflate the
airbags may have also damaged
important functions in the vehicle,
such as the fuel system, brake and
steering systems, etc. Even if the
vehicle appears to be drivable after
a moderate crash, there may be
concealed damage that could make
it difficult to safely operate the
vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the front outboard
passenger airbag.
. Airbags are designed to inflate
only once. After an airbag inflates,
you will need some new parts for the airbag system. If you do not
get them, the airbag system will
not be there to help protect you in
another crash. A new system will
include airbag modules and
possibly other parts. The service
manual for the vehicle covers the
need to replace other parts.
. The vehicle has a crash sensing
and diagnostic module which
records information after a crash.
See Vehicle Data Recording and
Privacy 0325 and Event Data
Recorders 0325.
. Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.
Passenger Sensing System
The vehicle has a passenger sensing
system for the front outboard
passenger position. The passenger
airbag status indicator will light on
the overhead console when the vehicle
is started.

Cadillac CT6 Owner Manual (GMNA-Localizing-MidEast-10293390) - 2017 -
CRC - 6/21/16
SEATS AND RESTRAINTS 81
.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

{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.

122 INSTRUMENTS AND CONTROLS
Uplevel Balanced Configuration
When the ignition is on, the fuel
gauge indicates about how much fuel
is left in the tank.
There is an arrow near the fuel gauge
pointing to the side of the vehicle the
fuel door is on.
When the indicator nears empty, the
low fuel light comes on. There still is
a little fuel left, but the vehicle should
be refueled soon. Here are four things that some owners
ask about. None of these show a
problem with the fuel gauge:
.
At the service station, the fuel
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel to
fill up than the gauge indicated.
For example, the gauge may have
indicated the tank was half full,
but it actually took a little more or
less than half the tank's capacity
to fill the tank.
. The gauge moves a little while
turning a corner or speeding up.
. The gauge takes a few seconds to
stabilize after the ignition is
turned on, and goes back to empty
when the ignition is turned off.
Boost Gauge (Performance
Configuration Only)
This gauge indicates boost under
heavier throttle.
It displays the air pressure level in the
intake manifold before it enters the
engine's combustion chamber.
The gauge is automatically centered at
zero every time the engine is started.
Actual boost is displayed from this
zero point. Changes in ambient
pressure, such as driving in mountains
and changing weather, will slightly
change the zero reading.

126 INSTRUMENTS AND CONTROLS
Passenger Safety Belt Reminder
Light
There is a passenger safety belt
reminder light near the passenger
airbag status indicator. SeePassenger
Sensing System 079.
When the vehicle is started, this light
flashes and a chime may come on to
remind passengers to fasten their
safety belt. Then the light stays on
solid until the belt is buckled. This
cycle continues several times if the
passenger remains or becomes
unbuckled while the vehicle is moving.
If the passenger safety belt is buckled,
neither the chime nor the light
comes on.
The front passenger safety belt
reminder light and chime may turn on
if an object is put on the seat such as
a briefcase, handbag, grocery bag,
laptop, or other electronic device. To turn off the reminder light and/or
chime, remove the object from the
seat or buckle the safety belt.
Airbag Readiness Light
This light shows if there is an
electrical problem with the airbag
system. The system check includes
the airbag sensor(s), the passenger
sensing system, the pretensioners, the
airbag modules, the wiring, and the
crash sensing and diagnostic module.
For more information on the airbag
system, see

The airbag readiness light comes on
for several seconds when the vehicle is
started. If the light does not come on
then, have it fixed immediately.
{Warning
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in the
vehicle might not inflate in a crash,
or they could even inflate without a
crash. To help avoid injury, have
the vehicle serviced right away.
If there is a problem with the airbag
system, a Driver Information Center
(DIC) message may also come on. See

INSTRUMENTS AND CONTROLS 127
When the vehicle is started, the
passenger airbag status indicator will
light the symbol for on and off for
several seconds as a system check.
Then, after several more seconds, the
status indicator will light either the on
or off symbol to let you know the
status of the front outboard passenger
frontal airbag and knee airbag.
If the on symbol is lit on the
passenger airbag status indicator, it
means that the front outboard
passenger frontal airbag and knee
airbag are allowed to inflate.
If the off symbol is lit on the airbag
status indicator, it means that the
passenger sensing system has turned
off the front outboard passenger
frontal airbag and knee airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be aproblem with the lights or the
passenger sensing system. See your
