14 KEYS, DOORS, AND WINDOWS
The climate control system will use
the previous settings during a remote
start. The rear window defogger may
come on during remote start based on
cold ambient conditions. The rear
window defogger indicator light does
not come on during remote start.
If the vehicle has auto heated or
ventilated seats they may come on
during a remote start. SeeHeated and
Ventilated Front Seats 043.
Laws in some local communities may
restrict the use of remote starters. For
example, some laws may require a
person using remote start to have the

SEATS AND RESTRAINTS 47
{Warning
A seat belt that is improperly
routed, not properly attached,
or twisted will not provide the
protection needed in a crash. The
person wearing the belt could be
seriously injured. After raising the
rear seatback, always check to be
sure that the seat belts are properly
routed and attached, and are not
twisted.
To raise a seatback: 1. Lift the seatback up and push it rearward to lock it in place.
2. Push and pull the top of the seatback to be sure it is locked into
position.
3. Repeat the steps to raise the other seatback, if necessary.

SEATS AND RESTRAINTS 61
locked, the interior lamps can be
turned off, and the hazard warning
flashers can be turned off using the
controls for those features. If any of
these systems are damaged in the
crash they may not operate as normal.
{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
0 403 and
Event Data Recorders 0403.
.Let only qualified technicians work
on the airbag system. 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.
The words ON and OFF, and the
symbols for on and off, will be visible
during the system check. When the
system check is complete, either the
word ON or OFF, and the symbol for
on or off, will be visible. See Passenger
Airbag Status Indicator 0107.
The passenger sensing system turns
off the front outboard passenger
frontal airbag under certain
conditions. No other airbag is affected
by the passenger sensing system.
The passenger sensing system works
with sensors that are part of the front
outboard passenger seat and seat belt.
The sensors are designed to detect the
presence of a properly seated
occupant and determine if the front
outboard passenger frontal airbag
should be allowed to inflate or not.

and Indicators
Warning lights and gauges can signal
that something is wrong before it
becomes serious enough to cause an
expensive repair or replacement.
Paying attention to the warning lights
and gauges could prevent injury.
Some warning lights come on briefly
when the engine is started to indicate
they are working. When one of the
warning lights comes on and stays on
while driving, or when one of the
gauges shows there may be a problem,
check the section that explains what
to do. Waiting to do repairs can be
costly and even dangerous.

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14590481) - 2021 - CRC - 10/22/20
108 INSTRUMENTS AND CONTROLS
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See your
dealer for service.
{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 Light0107 for
more information, including
important safety information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned on,
but the engine is not running, as a check to show the light is working.
It should go out when the engine is
started.
If the light stays on, or comes on
while driving, there may be a problem
with the electrical charging system.
Have it checked by your dealer.
Driving while this light is on could
drain the battery.
When this light comes on, or is
flashing, the Driver Information
Center (DIC) also displays a message.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio and
air conditioner. Find a safe place to
stop the vehicle.
Malfunction Indicator Lamp
(Check Engine Light)
This light is part of the vehicle’s
emission control on-board diagnostic
system. If this light is on while the
engine is running, a malfunction has
been detected and the vehicle may
require service. The light should come
on to show that it is working when
the ignition is in Service Mode. See
Ignition Positions
0224.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when it
comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not run
smoothly. This could lead to costly
repairs that might not be covered
by the vehicle warranty.

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14590481) - 2021 - CRC - 10/22/20
INSTRUMENTS AND CONTROLS 109
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not meet
the original tire specifications, can
cause this light to come on. This
could lead to costly repairs not
covered by the vehicle warranty.
This could also affect the vehicle’s
ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications0294.
If the light is f lashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service may
be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades.
If towing a trailer, reduce the amount
of cargo being hauled as soon as
possible. If the light continues to flash, find a
safe place to park. Turn the vehicle off
and wait at least 10 seconds before
restarting the engine. If the light is
still flashing, follow the previous
guidelines and see your dealer for
service as soon as possible.
If the light is on steady :
A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
.If fuel has been added to the vehicle
using the capless fuel funnel
adapter, make sure that it has been
removed. See “Filling the Tank with
a Portable Gas Can ”under Filling the
Tank 0277. The diagnostic system
can detect if the adapter has been
left installed in the vehicle, allowing
fuel to evaporate into the
atmosphere. A few driving trips with
the adapter removed may turn off
the light.
.Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed up.
If this occurs, change the fuel brand. It may require at least one
full tank of the proper fuel to turn
the light off. See
Recommended Fuel
(3.6L V6 Engine) 0276 or
Recommended Fuel (2.0L L4 Engine)
0 276.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the
