Seats and Restraints 43
The parts of the airbag that come into
contact with you may be warm, but not too
hot to touch. There may be some smoke
and dust coming from the vents in the
deflated airbags. Airbag inflation does not
prevent the driver from seeing out of the
windshield or being able to steer the
vehicle, nor does it prevent people from
leaving the vehicle.
{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
after the airbags inflate. The feature may also activate, without airbag inflation, after
an event that exceeds a predetermined
threshold. After turning the ignition off and
then on again, the doors can be 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 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 attempting to restart the
vehicle after a crash has occurred.
If an airbag inflates or the vehicle has been
in a crash, the sensing system may shut
down the high voltage system. When this
occurs, the high voltage battery is
disconnected and the vehicle will not start.
Before the vehicle can be operated again, it
must be serviced at your dealer. 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 0272 and
Event Data Recorders 0272.
.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.

Seats and Restraints 47
Warning (Continued)
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 047 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 0270.
{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

Warning Lights, Gauges, 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 propulsion system 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.
Instrument Cluster
The instrument cluster displays a preview of
information that includes electric range,
charging, odometer, and battery status. This
happens upon entry when the driver door is
opened, before starting the vehicle. This
preview will dismiss after starting the

Trip Odometer
The trip odometer shows how far the
vehicle has been driven since the trip
odometer was last reset.
The trip odometer is accessed and reset
through the Driver Information Center (DIC).
SeeDriver Information Center (DIC) 099.
Battery Gauge (High Voltage)
Enhanced Battery Gauge
This displays the high voltage battery state
of charge. The value in the center is an
estimate of how far the vehicle can be
driven on the remaining charge based on
driving habits and conditions learned over
several days. The Max and Min values above and below
the display indicate the longest and shortest
possible range as estimated from current
vehicle conditions and climate settings.
The mileage estimate and Max and Min
numbers are affected by climate control
system usage. Estimated range may increase
or decrease based on changes in climate
control energy consumption.
A trend bar on the far left estimates how
recent driving habits, conditions, and climate
settings are affecting the range prediction.
When the high voltage battery state of
charge is very low, the estimated range
value in the center will change to Low. Max
and Min ranges will no longer be displayed.
Additional alerts may display and a sound
may also be heard at low state of charge.

the high voltage battery is fully charged.
During normal operation, a slight reductionin discharge power may occur as the high
voltage battery state of charge decreases.
The power indicator gauge value shows the
instantaneous power used by the battery.
Regenerative Braking
When regenerative braking is active, the
regen battery icon with arrows appears
green. The power indicator gauge value
shows the amount of instantaneous power
being regenerated.
Regenerative Power Limited
Regenerative power may be limited when
the high voltage battery is near full charge
or cold. The regen battery icon will appear
gray when limited, and a horizontal bar may
display on the gauge, at the level of the
vehicle’s maximum regenerative braking
power.
Seat Belt Reminders
Driver Seat Belt Reminder Light
There is a driver seat belt reminder light on
the instrument cluster.
When the vehicle is started, this light
flashes and a chime may come on to remind
the driver to fasten their seat belt. Then the
light stays on solid until the belt is buckled.
This cycle may continue several times if the
driver remains or becomes unbuckled while
the vehicle is moving.
If the driver seat belt is buckled, neither the
light nor the chime comes on.
Passenger Seat Belt Reminder Light
There is a passenger seat belt reminder light
near the passenger airbag status indicator.
When the vehicle is started, this light
flashes and a chime may come on to remind
passengers to fasten their seat belt. Then
