If equipped with an RKE transmitter and
OnStar, refer to“Theft Alarm Notification" in
OnStar Security 0265.
Programming Transmitters to the Vehicle
Only RKE transmitters programmed to the
vehicle will work. If a transmitter is lost or
stolen, a replacement can be purchased and
programmed through your dealer. When the
replacement transmitter is programmed to
the vehicle, all remaining transmitters must
also be programmed. Any lost or stolen
transmitters no longer work once the new
transmitter is programmed. Each vehicle can
have up to four transmitters programmed
to it.
Battery Replacement
{Warning
Never allow children to play with the RKE
transmitter. The transmitter contains a
small battery, which can be a choking
hazard. If swallowed, internal burns can
occur, resulting in severe injury or death.
Seek medical attention immediately if a
battery is swallowed.
{Warning
To avoid personal injury, do not touch
metal surfaces on the RKE transmitter
when it has been exposed to extreme
heat. These surfaces can be hot to the
touch at temperatures above 59 °C
(138 °F).
Caution
When replacing the battery, do not touch
any of the circuitry on the transmitter.
Static from your body could damage the
transmitter.
Caution
Always replace the battery with the
correct type. Replacing the battery with
an incorrect type could potentially create
a risk of battery explosion. Dispose of
used batteries according to instructions
and local laws. Do not attempt to burn,
crush, or cut the used battery, and avoid
exposing the battery to environments
with extremely low air pressures or high
temperatures.
Caution
If the RKE transmitter is not reassembled
properly, liquids could enter the housing
and damage the circuitry, resulting in an
RKE transmitter malfunction and/or
failure. To prevent damage, always follow
the steps for RKE transmitter reassembly
in this manual to ensure the transmitter
is sealed properly whenever the RKE
transmitter is opened.
Replace the battery if the DIC displays
REPLACE BATTERY IN REMOTE KEY.
To replace the battery:

Squeeze both sides of the release button
and pull outward. Then move the height
adjuster up or down to the desired position
and release the button.
After the adjuster is set to the desired
position, try to move it up or down without
squeezing the release button to make sure it
has locked into position.
Seat Belt Pretensioners
If the vehicle has seat-mounted side impact
airbags and roof-rail airbags, it also has seat
belt pretensioners for the front outboard
occupants.
Although the seat belt pretensioners cannot
be seen, they are part of the seat belt
assembly. They can help tighten the seat
belts during the early stages of a moderate
to severe frontal, near frontal, or rear crash
if the threshold conditions for pretensioner
activation are met. And, if the vehicle has
roof-rail airbags, seat belt pretensioners can
help tighten the seat belts in a side crash or
a rollover event.Pretensioners work only once. If the
pretensioners activate in a crash, the
pretensioners and probably other parts of
the vehicle’s seat belt system will need to
be replaced. See
Replacing Seat Belt System
Parts after a Crash 035.
Do not sit on the outboard seat belt while
entering or exiting the vehicle or at any
time while sitting in the seat. Sitting on the
seat belt can damage the webbing and
hardware.
Rear Seat Belt Comfort Guides
Rear seat belt comfort guides may provide
added seat belt comfort for older children
who have outgrown booster seats and for
some adults. When installed on a shoulder
belt, the comfort guide positions the
shoulder belt away from the neck and head.
Comfort guides are available through your
dealer for the rear outboard seating
positions. Instructions are included with the
comfort guides.
Seat Belt Use During Pregnancy
Seat belts work for everyone, including
pregnant women. Like all occupants, they
are more likely to be seriously injured if
they do not wear seat belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap portion should
be worn as low as possible, below the
rounding, throughout the pregnancy.

16547501) - 2023 - CRC - 6/10/22
34 Seats and Restraints
The best way to protect the fetus is to
protect the mother. When a seat belt is
worn properly, it is more likely that the
fetus will not be hurt in a crash. For
pregnant women, as for anyone, the key to
making seat belts effective is wearing them
properly.
Seat Belt Extender
If the vehicle's seat belt will fasten around
you, you should use it.
But if a seat belt is not long enough, your
dealer will order you an extender. Only a
GM dealer issued extender should be used.
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
restraints. For more information on the
proper use and fit of seat belt extenders see
the instruction sheet that comes with the
extender.
Safety System Check
Periodically check the seat belt reminder,
seat belts, buckles, latch plates, retractors,
shoulder belt height adjusters (if equipped),
and seat belt anchorages to make sure they
are all in working order. Look for any other
loose or damaged seat belt system parts
that might keep a seat belt system from
performing properly. See your dealer to
have it repaired. Torn, frayed, or twisted
seat belts may not protect you in a crash.
Torn or frayed seat belts can rip apart under
impact forces. If a belt is torn or frayed,
have it replaced immediately. If a belt is
twisted, it may be possible to untwist by
reversing the latch plate on the webbing.
If the twist cannot be corrected, ask your
dealer to fix it.
Make sure the seat belt reminder light is
working. SeeSeat Belt Reminders 075.
Keep seat belts clean and dry. See Seat Belt
Care 034.
Seat Belt Care
Keep belts clean and dry.
Seat belts should be properly cared for and
maintained.
Seat belt hardware should be kept dry and
free of dust or debris. As necessary, exterior
hard surfaces and seat belt webbing may be
lightly cleaned with mild soap and water.
Ensure there is not excessive dust or debris
in the mechanism. If dust or debris exists in
the system please see the dealer. Parts may
need to be replaced to ensure proper
functionality of the system.
{Warning
Do not bleach or dye seat belt webbing.
It may severely weaken the webbing. In
a crash, they might not be able to
provide adequate protection. Clean and
rinse seat belt webbing only with mild
soap and lukewarm water. Allow the
webbing to dry.

36 Seats and Restraints
If the van is equipped with a sliding door,
the roof-rail airbag for the front outboard
passenger is separate from the roof-rail
airbag for the second and third row
passengers seated directly behind the
front outboard passenger. If the van is
equipped with a 60/40 swing-out door, a
single roof-rail airbag covers all three
seating positions.
Additionally:
.Vehicles that have a raised or modified
roof —such as school buses, ambulances,
vehicles with adaptive equipment for
mobility, and recreational vehicles —may
or may not be equipped with roof-rail
airbags.
.Vehicles with a GVWR above 4 536 kg
(10,000 lb) may be equipped with
roof-rail airbags.
All vehicle airbags have the word AIRBAG on
the trim or on an attached label near the
deployment opening.
For frontal airbags, the word AIRBAG is on
the center of the steering wheel for the
driver and on the instrument panel for the
front outboard passenger. For seat-mounted side impact airbags, the
word AIRBAG is on the side of the seatback
or side of the seat closest to the door.
For roof-rail airbags, the word AIRBAG is on
the ceiling or trim.
Airbags are designed to supplement the
protection provided by seat belts. Even
though today’s airbags are also designed to
help reduce the risk of injury from the force
of an inflating airbag, all airbags must
inflate very quickly to do their job.
Here are the most important things to know
about the airbag system:
{Warning
You can be severely injured or killed in a
crash if you are not wearing your seat
belt, even with airbags. Airbags are
designed to work with seat belts, not
replace them. Also, airbags are not
designed to inflate in every crash. In
some crashes seat belts are the only
restraint. See
When Should an Airbag
Inflate? 039.
(Continued)
Warning (Continued)
Wearing your seat belt during a crash
helps reduce your chance of hitting
things inside the vehicle or being ejected
from it. Airbags are“supplemental
restraints” to the seat belts. Everyone in
the vehicle should wear a seat 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. Seat belts help
keep you in position before and during a
crash. Always wear a seat belt, even with
airbags. The driver should sit as far back
as possible while still maintaining control
of the vehicle. The seat belts and the
front outboard passenger airbags are (Continued)

38 Seats and Restraints
If the vehicle has seat-mounted side impact
airbags for the driver and front outboard
passenger, they are in the sides of the
seatbacks closest to the door.
Driver Side Shown, Passenger Side Similar
If the vehicle has a single seating row and it
has roof-rail airbags for the driver and front
outboard passenger, the roof-rail airbags are
in the ceiling above the side windows.
Driver Side Shown, Passenger Side Similar
If the vehicle has two seating rows, roof-rail
airbags for the driver, front outboard
passenger, and second row outboard
passengers are in the ceiling above the side
windows. If the vehicle has three or more
seating rows, roof-rail airbags for the driver,
front outboard passenger, and second and
third row outboard passengers are in the
ceiling above the side windows.
{Warning
If something is between an occupant and
an airbag, the airbag might not inflate
properly or it might force the object into
that person causing severe injury or even
death. The path of an inflating airbag
must be kept clear. Do not put anything
between an occupant and an airbag, and
do not attach or put anything on the
steering wheel hub or on or near any
other airbag covering.
Do not use seat accessories that block the
inflation path of a seat-mounted side
impact airbag.
Never secure anything to the roof of a
vehicle with roof-rail airbags by routing a
rope or tie‐down through any door or
window opening. If you do, the path of
an inflating roof-rail airbag will be
blocked.

When Should an Airbag Inflate?
This vehicle is equipped with one or more
airbags. SeeAirbag System 035. Airbags are
designed to inflate if the impact exceeds the
specific airbag system's deployment
threshold. Deployment thresholds are used
to predict how severe a crash is likely to be
in time for the airbags to inflate and help
restrain the occupants. The vehicle has
electronic sensors which help the airbag
system determine the severity of the
impact. Deployment thresholds can vary
with specific vehicle design.
Frontal airbags are designed to inflate in
moderate to severe frontal crashes to help
reduce the potential for severe injuries
mainly to the driver or front outboard
passenger head and chest.
Whether the frontal airbags will or should
deploy is not based primarily on how fast
the vehicle is traveling. It depends largely
on what you hit, the direction of the
impact, and how quickly the vehicle
slows down. Frontal airbags may inflate at different crash
speeds depending on whether the vehicle
hits an object straight on or at an angle,
and whether the object is fixed or moving,
rigid or deformable, narrow or wide.
Frontal airbags are not intended to inflate
during vehicle rollovers, rear impacts, or in
many side impacts.
Seat-mounted side impact airbags are
designed to inflate in moderate to severe
side crashes depending on the location of
the impact. These airbags may also inflate
in some moderate to severe frontal impacts.
Seat-mounted side impact airbags are not
designed to inflate in rollovers or rear
impacts. A seat-mounted side impact airbag
is designed to inflate on the side of the
vehicle that is struck.
The vehicle may or may not be equipped
with roof-rail airbags. Roof-rail airbags are
designed to inflate in moderate to severe
side crashes depending on the location of
the impact. In addition, these roof-rail
airbags are designed to inflate during a
rollover. Roof-rail airbags are not designed
to inflate in frontal, near-frontal, or rear
impacts. All roof-rail airbags will inflatewhen either side of the vehicle is struck or if
the sensing system predicts that the vehicle
is about to roll over on its side.
In any particular crash, no one can say
whether an airbag should have inflated
simply because of the vehicle damage or
repair costs.
What Makes an Airbag Inflate?
In a deployment event, the sensing system
sends an electrical signal triggering a release
of gas from the inflator. Gas from the
inflator fills the airbag causing the bag to
break out of the cover. The inflator, the
airbag, and related hardware are all part of
the airbag module.
For airbag locations, see
Where Are the
Airbags? 037.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal
collisions, even belted occupants can contact
the steering wheel or the instrument panel.
In moderate to severe side collisions, even
belted occupants can contact the inside of
the vehicle.

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 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 0262 and
Event Data Recorders 0262.
.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.
Airbag On-Off Switch
If the instrument panel has one of the
switches pictured in the following
illustrations, the vehicle has an airbag on-off
switch that you can use to manually turn
on or off the front outboard passenger
airbag. No other airbag is affected by the
airbag on-off switch.

Replacing Airbag System Parts
after a Crash
{Warning
A crash can damage the airbag systems
in the vehicle. A damaged airbag system
may not properly 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 075.
Child Restraints
Older Children
Older children who have outgrown booster
seats should wear the vehicle’s seat belts.
Refer to How to Wear Seat Belts Properly
0 29.
The manufacturer instructions that come
with the booster seat state the weight and
height limitations for that booster. Use a
booster seat with a lap-shoulder belt until
the child passes the fit test below:
.Sit all the way back on the seat. Do the
knees bend at the seat edge? If yes,
continue. If no, return to the booster seat.
.Buckle the lap-shoulder belt. Does the
shoulder belt rest on the shoulder? If yes,
continue. If no, try using the rear seat
belt comfort guide, if available. See “Rear
Seat Belt Comfort Guides” under
Lap-Shoulder Belt 031. If a comfort guide
is not available, or if the shoulder belt
still does not rest on the shoulder, then
return to the booster seat.
.Does the lap belt fit low and snug on the
hips, touching the thighs? If yes, continue.
If no, return to the booster seat.
.Can proper seat belt fit be maintained for
the length of the trip? If yes, continue.
If no, return to the booster seat.
Q: What is the proper way to wear seat belts?
A: An older child should wear a lap-shoulder
belt and get the additional restraint a
shoulder belt can provide. The shoulder
belt should not cross the face or neck.
The lap belt should fit snugly below the
hips, just touching the top of the thighs.
This applies belt force to the child's
pelvic bones in a crash. It should never
be worn over the abdomen, which could
cause severe or even fatal internal
injuries in a crash.
