Auto Heated Seats
If equipped, the controls can be
accessed while the vehicle is on by
pressing
LorMon the center
stack.
When the vehicle is on, this feature
will automatically activate the
heated seats at the level required by
the vehicle's interior temperature.
The active high, medium, low, or off
heated seat level will be indicated
by the manual heated seat button
lights on the center stack. Use the
manual heated seat buttons on the
center stack to turn auto heated
seats off.
If the passenger seat is unoccupied,
the auto heated seats feature will
not activate that seat.
The auto heated seats feature can
be programmed to always be
enabled when the vehicle is on. See
Vehicle Personalization 0141. Remote Start Auto Heated Seats
When it is cold outside, the heated
seats turn on automatically during a
remote vehicle start. If the vehicle
has auto heated seats, the seat
heating level will automatically
change to the level required by the
vehicle's interior temperature when
the vehicle is turned on.
The indicator lights on the heated
seat buttons do not turn on during a
remote start.
The temperature performance of an
unoccupied seat may be reduced.
This is normal.
The heated seats will not turn on
during a remote start unless the
heated seats feature is enabled in
the vehicle personalization menu.
See
Vehicle Personalization 0141.
Rear Seats
Folding the Seatback
{Warning
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.
{Warning
A safety 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 safety belts are
properly routed and attached, and
are not twisted.

Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety belt is not long
enough, your dealer will order you
an extender. When you go in to
order it, take the heaviest coat you
will wear, so the extender will be
long enough for you. To help avoid
personal injury, do not let someone
else use it, and use it only for the
seat it is made to fit. The extender
has been designed for adults. Never
use it for securing child seats. To
wear it, attach it to the regular safety
belt. For more information, see the
instruction sheet that comes with
the extender.
Safety System Check
Now and then, check that the safety
belt reminder light, safety belts,
buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
from doing its job. See your dealer
to have it repaired. Torn or frayedsafety belts may not protect you in a
crash. They can rip apart under
impact forces. If a belt is torn or
frayed, get a new one right away.
Make sure the safety belt reminder
light is working. See
Safety Belt
Reminders 0107.
Keep safety belts clean and dry.
See Safety Belt Care 062.
Safety Belt Care
Keep belts clean and dry.
{Warning
Do not bleach or dye safety belt
webbing. It may severely weaken
the webbing. In a crash, they
might not be able to provide
adequate protection. Clean and
rinse safety belt webbing only
with mild soap and lukewarm
water. Allow the webbing to dry.
Replacing Safety Belt
System Parts after a
Crash
{Warning
A crash can damage the safety
belt system in the vehicle.
A damaged safety belt system
may not properly protect the
person using it, resulting in
serious injury or even death in a
crash. To help make sure the
safety belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.
After a minor crash, replacement of
safety belts may not be necessary.
But the safety belt assemblies that
were used during any crash may
have been stressed or damaged.
See your dealer to have the safety
belt assemblies inspected or
replaced.

64 Seats and Restraints
{Warning
You can be severely injured or
killed in a crash if you are not
wearing your safety belt, even
with airbags. Airbags are
designed to work with safety
belts, not replace them. Also,
airbags are not designed to inflate
in every crash. In some crashes
safety belts are the only restraint.
SeeWhen Should an Airbag
Inflate? 066.
Wearing your safety belt during a
crash helps reduce the chance of
hitting things inside the vehicle or
being ejected from it. Airbags are
“supplemental restraints” to the
safety belts. Everyone in the
vehicle should wear a safety belt
properly, whether or not there is
an airbag for that person.
{Warning
Because airbags inflate with great
force and faster than the blink of
an eye, anyone who is up
against, or very close to any
airbag when it inflates can be
seriously injured or killed. Do not
sit unnecessarily close to any
airbag, as you would be if sitting
on the edge of the seat or leaning
forward. Safety belts help keep
you in position before and during
a crash. Always wear a safety
belt, even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle. The safety belts and
the front outboard passenger
airbags are most effective when
you are sitting well back and
upright in the seat with both feet
on the floor.
Occupants should not lean on or
sleep against the door or side
windows in seating positions with
seat-mounted side impact airbags
and/or roof-rail airbags.
{Warning
Children who are up against,
or very close to, any airbag when
it inflates can be seriously injured
or killed. Always secure children
properly in the vehicle. To read
how, see Older Children 075 or
Infants and Young Children 077.
There is an airbag readiness light
on the instrument cluster, which
shows the airbag symbol. The
system checks the airbag electrical
system for malfunctions. The light
tells you if there is an electrical
problem. See Airbag Readiness
Light 0108 for more information.

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
9807421) - 2017 - CRC - 11/18/15

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.
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. The SERVICE VEHICLE
SOON message in the Driver
Information Center (DIC) will be
displayed. 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 0353
and Event Data
Recorders 0353.
. 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.

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
9807421) - 2017 - CRC - 11/18/15
Seats and Restraints 71
.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 to remind you
that the airbags are off. See
Passenger Airbag Status
Indicator 0108.
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 airbags to
be enabled, the on indicator will light
and stay lit as a reminder that the
airbags 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 0108 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 Front
Seat) 090 orSecuring Child
Restraints (With the Safety Belt
in the Rear Seat) 088.
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

Seats and Restraints 73
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”
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 074
for more information about
modifications that can affect how
the system operates. A wet seat can affect the
performance of the passenger
sensing system. Here is how:
.
The passenger sensing system
may turn off the passenger
frontal airbag and passenger
knee airbag when liquid is
soaked into the seat. If this
happens, the off indicator will be
lit, and the airbag readiness light
on the instrument panel will also
be lit.
. Liquid pooled on the seat that
has not soaked in may make it
more likely that the passenger
sensing system will turn on the
passenger frontal airbag and
passenger knee airbag while a
child restraint or child occupant
is on the seat. If the passenger
frontal airbag and passenger
knee airbag are turned on, the
on indicator will be lit.
If the passenger seat gets wet, dry
the seat immediately. If the airbag
readiness light is lit, do not install a
child restraint or allow anyone to occupy the seat. See
Airbag
Readiness Light 0108 for important
safety information.
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

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
9807421) - 2017 - CRC - 11/18/15
Seats and Restraints 75
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 Light0108.
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? 065. See your dealer
for service.
Replacing Airbag System
Parts after a Crash
{Warning
A crash can damage the airbag
systems in the vehicle.
A damaged airbag system may
not work properly and may not
protect you and your
passenger(s) in a crash, resulting
in serious injury or even death. To
help make sure the airbag
systems are working properly
after a crash, have them
inspected and any necessary
replacements made as soon as
possible.
If an airbag inflates, you will need to
replace airbag system parts. See
your dealer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly. Have
the vehicle serviced right away. See
Airbag Readiness Light 0108.
Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the
vehicle safety belts.
