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 036.
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
This vehicle may have rear seat belt comfort
guides. The guides may provide added seat
belt comfort for older children who have
outgrown booster seats and for some adults.
When installed and properly adjusted, the
comfort guide positions the shoulder belt
away from the neck and head.The comfort guides for the right rear
outboard seating positions of
three-passenger bench seats are stored in a
pocket on the side of the seatback.
Adjustable comfort guides are available
through your dealer for the left rear
outboard seating positions of the
three-passenger bench seats and for the

New parts and repairs may be necessary
even if the seat belt system was not being
used at the time of the crash.
Have the seat belt pretensioners checked if
the vehicle has been in a crash, or if the
airbag readiness light stays on after you
start the vehicle or while you are driving.

38 Seats and Restraints
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. SeeWhen Should an Airbag
Inflate? 040.
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
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 046 or
Infants and Young Children 047.
There is an airbag readiness light on the
instrument panel, 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 075.

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 (Continued)
Warning (Continued)
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 037. 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 or near-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,
if equipped, are designed to inflate in
moderate to severe side crashes depending
on the location of the impact. Seat-mounted
side impact airbags are not designed to

Chevrolet Express Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15555951) - 2022 - CRC - 1/27/22
Seats and Restraints 41
inflate in frontal impacts, near-frontal
impacts, rollovers, or rear impacts.
A seat-mounted side impact airbag is
intended 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 inflate
when 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 tobreak 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? 039.
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.
Airbags supplement the protection provided
by seat belts by distributing the force of the
impact more evenly over the
occupant's body.
Rollover capable roof-rail airbags are
designed to help contain the head and chest
of occupants in the outboard seating
positions in the first, second, and third rows,
if equipped. The rollover capable roof-rail
airbags are designed to help reduce the risk
of full or partial ejection in rollover events,
although no system can prevent all such
ejections. But airbags would not help in many types
of collisions, primarily because the
occupant's motion is not toward those
airbags. See
When Should an Airbag Inflate?
0 40.
Airbags should never be regarded as
anything more than a supplement to seat
belts.
What Will You See after an
Airbag Inflates?
After frontal and seat-mounted side impact
airbags (if equipped) inflate, they quickly
deflate, so quickly that some people may
not even realize the airbags inflated.
Roof-rail airbags (if equipped) may still be at
least partially inflated for some time after
they inflate. Some components of the airbag
module may be hot for several minutes. For
location of the airbags, see Where Are the
Airbags? 039.
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

To turn the front outboard passenger airbag
on again, insert the ignition key into the
airbag on-off switch, push in, and move the
switch to the ON position.
The front outboard passenger frontal airbag
is now enabled, and may inflate. SeeAirbag
On-Off Light 076.
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 0266.
{Warning
For up to 10 seconds after the vehicle is
turned off and the 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
.Front seats, including stitching, seams or
zippers
.Seat belts
.Steering wheel, instrument panel, 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.
If the vehicle has rollover roof-rail airbags,
see
Different Size Tires and Wheels 0218 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 0260.
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 075.

occur when things like storms and power
lines interfere with radio reception. When
this happens, try reducing the treble on the
radio.
SiriusXM Satellite Radio Service
If equipped, SiriusXM Satellite Radio Service
provides digital radio reception. Tall
buildings or hills can interfere with satellite
radio signals, causing the sound to fade in
and out. In addition, traveling or standing
under heavy foliage, bridges, garages,
or tunnels may cause loss of the SiriusXM
signal for a period of time. Some cellular
services may interfere with SXM reception
causing loss of signal.
Mobile Device Usage
Mobile device usage, such as making or
receiving calls, charging, or just having the
mobile device on may cause static
interference in the radio. Unplug the mobile
device or turn it off if this happens.
Fixed Mast Antenna
The fixed mast antenna will go through
most car washes as long as it is securely
attached. If the antenna becomes slightly
bent, straighten it out by hand. If it is badly
bent, replace it.Occasionally check that the antenna is tight
at the base. If tightening is required, protect
the paint from damage.
Multi-Band Antenna
The roof antenna may be used for radio,
navigation, and OnStar, depending on the
equipped options. Keep clear of obstructions
for clear reception. If the vehicle has a
sunroof, and it is open, reception can also
be affected.
Audio Players
Avoiding Untrusted Media Devices
When using media devices such as CDs,
DVDs, Blu-ray Discs, SD cards, USB devices,
and mobile devices, consider the source.
Untrusted media devices could contain files
that affect system operation or performance.
Avoid use if the content or origin cannot be
trusted.
Auxiliary Devices
Using the Auxiliary Input Jack
Radios with an auxiliary input jack on the
lower right side can connect to an external
audio device such as an iPod, MP3 player,
or CD player for use as another source for
audio listening. This input jack is not an
audio output; do not plug headphones into
the front auxiliary input jack.
Drivers are encouraged to set up any
auxiliary device while the vehicle is in
P (Park). See
Defensive Driving 0121 for
more information on driver distraction.
To use a portable audio player, connect a
3.5 mm (1/8 in) cable to the radio's front
auxiliary input jack. When a device is
connected, press the radio CD/AUX button
to begin playing audio from the device over
the vehicle speakers.
For optimal sound quality, increase the
portable audio device's volume to the
loudest level.
It is always best to power the portable
audio device through its own battery while
playing.
O: Turn clockwise or counterclockwise to
increase or decrease the volume of the
portable player. Additional volume
adjustments might have to be made from
the portable device if the volume is not loud
or soft enough.
