74 Seats and Restraints
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. SeeAirbag
Readiness Light 0136.Airbag System
The vehicle has the following
airbags:
.
A frontal airbag for the driver
. A frontal airbag for the front
outboard passenger
. A seat-mounted side impact
airbag for the driver
. A seat-mounted side impact
airbag for the front outboard
passenger
. A roof-rail airbag for the driver
and for the second and third row
passengers seated directly
behind the driver
. A roof-rail airbag for the front
outboard passenger and the
second and third row
passengers seated directly
behind the front outboard
passenger
The vehicle may have the following
airbag:
. A front center airbag for the
driver and front outboard
passenger 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 the front center airbag, the word
AIRBAG is on the inboard side of
the driver seatback.
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 bag, all airbags must inflate
very quickly to do their job.
Here are the most important things
to know about the airbag system:

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-13566622) - 2020 - CRC - 4/15/19
Seats and Restraints 75
{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? 078.
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.
(Continued)
Warning (Continued)
Occupants should not lean on or
sleep against the front center
armrest or console in vehicles
with a front center airbag.
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, seeOlder Children 087 or
Infants and Young Children 089.

If the vehicle has a front center
airbag, it is in the inboard side of the
driver seatback.
Driver Side Shown, PassengerSide Similar
The driver and front outboard
passenger seat-mounted side
impact airbags are in the side of the
seatbacks closest to the door.

The roof-rail airbags for the driver,
front outboard passenger, and
second and third row outboard
seating positions 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 (Continued)
Warning (Continued)
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 or console
accessories that block the
inflation path of a seat-mounted
side impact airbag or the front
center airbag, if equipped.
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
airbags. SeeAirbag System 074.
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 that 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's or
front outboard passenger's head
and chest.
Whether the frontal airbags will or
should inflate is not based primarily
on how fast the vehicle is traveling. It depends on what is 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 many side impacts.
In addition, the vehicle has
advanced technology frontal
airbags. Advanced technology
frontal airbags adjust the restraint
according to crash severity.
The vehicle also has a seat position
sensor that enables the sensing
system to monitor the position of the
driver seat. The seat position sensor
provides information that is used to
adjust the deployment of the driver
frontal airbag.
The front center airbag, if equipped,
is designed to inflate in moderate to
severe side crashes dependingupon the location of the impact,
when either side of the vehicle is
struck. In addition, the front center
airbag is designed to inflate when
the sensing system predicts that the
vehicle is about to roll over on its
side. The front center airbag is not
designed to inflate in frontal
impacts, near frontal impacts,
or rear impacts.
Seat-mounted side impact airbags
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 inflate in frontal
impacts, near frontal impacts,
rollovers, or rear impacts.
A seat-mounted side impact airbag
is designed to inflate on the side of
the vehicle that is struck.
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 or in a
severe frontal impact. Roof-rail
airbags are not designed to inflate in

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-13566622) - 2020 - CRC - 4/15/19
Seats and Restraints 79
rear impacts. Both roof-rail airbags
will inflate when either side of the
vehicle is struck, if the sensing
system predicts that the vehicle is
about to roll over on its side, or in a
severe frontal impact.
In any particular crash, no one can
say whether an airbag should have
inflated simply because of the
vehicle damage or the 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, seeWhere Are
the Airbags? 076.
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. 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? 078.
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 inflate, they quickly
deflate, so quickly that some people
may not even realize the airbags
inflated. The front center airbag and
roof-rail airbags 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? 076.
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
