56 Seats and Restraints
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 052.
If the vehicle has rollover roof-rail airbags,
see Different Size Tires and Wheels 0301 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 0348.
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 092.
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? 048. See your dealer
for service.

Caution (Continued)
run smoothly. This could lead to costly
repairs that might not be covered by the
vehicle warranty.
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 Modifications0258.
Light Flashing
If the light is flashing : 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.
Light on Steady
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 funnel adapter, make
sure that it has been removed. See
“Filling the Tank with a Portable Gas Can”
under Filling the Tank 0247. 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 (LYX - 1.5L L4
Turbo Engine) 0246.
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 vehicle may affect vehicle

1-877-NAV-DISC (1-877-628-3472) or see
www.gmnavdisc.com. If updates are needed,
call the GM Nav Disc Center or order online.
Over-the-Air-Vehicle Map Updates
If equipped, the infotainment system can
receive map updates over the air. Map
updates occur within a 161 km (100 mi)
radius around the home address on file. This
boundary will adjust over time based on
driving patterns. The vehicle uses a
Cloud-connected service to receive the date
and downloads it to the system’s onboard
SD card, if equipped. A data plan or
compatible mobile device hotspot is
required. The SD card is required for
navigation system function.
When a map update is available, a prompt
will appear on the infotainment display.
Once the update is accepted, it will
download and run in the background
without interruption any infotainment
functions. The download will carry over
ignition cycles, stopping and starting where
it left off. The updates can be set to
download automatically.See www.gmnavdisc.com for information on
ordering, purchasing, and installing a new or
replacement SD card. Features are subject to
change. For more information on this
feature, see my.gmc.com/learn.Database Coverage Explanations
Coverage areas vary with respect to the
level of map detail available for any given
area. Some areas feature greater levels of
detail than others. If this happens, it does
not mean there is a problem with the
system. As the map data is updated, more
detail can become available for areas that
previously had limited detail. See
Map Data
Updates 0149.
Voice Recognition
If equipped, voice recognition allows for
hands-free operation within the navigation,
audio, phone, and weather applications. This
feature can be started by pressing
gon the
steering wheel or touching
gon the
infotainment display. However, not all features within these areas
are supported by voice commands.
Generally, only complex tasks that require
multiple manual interactions to complete
are supported by voice commands.
For example, tasks that take more than one
or two touches, such as a song or artist to
play from a media device, would be
supported by voice commands. Other tasks,
like adjusting the volume or seeking up or
down, are audio features that are easily
performed by touching one or two options,
and are not supported by voice commands.
In general there are flexible ways to speak
commands for completing the tasks.
If your language supports it, try stating a
one-shot command, such as
“Directions to
address province>.” Do not include the ZIP code
while stating the address during the
command. Another example of a one-shot
Destination Entry command is, “Directions to
Place of Interest at .” If these
commands do not work, try saying, “Take
me to Place of Interest” or“Find address”
and the system will walk you through by
asking additional questions.
