side instrument panel.
Driver Side Shown, PassengerSide Similar
If the vehicle has seat-mounted side
impact airbags for the driver and
front outboard passenger, they are
in the side of the seatbacks closest
to the door.
Driver Side Crew Cab Shown, Passenger Side Double and Regular Cabs Similar
If the vehicle has roof-rail airbags
for the driver, front outboard
passenger, and second row
outboard passengers, they 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 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
airbags. SeeAirbag System 073.
Airbags are designed to inflate if the
impact exceeds the specific airbag

sensing system predicts that the
vehicle is about to roll over on its
side, or in a severe frontal impact.
Vehicles with a GVWR above
3 855 kg (8,500 lb) up to and
including 4 536 kg (10,000 lb) also
have roof-rail airbags. These
roof-rail airbags are designed to
inflate in moderate to severe side
crashes depending on the location
of the impact. Both roof-rail airbags
will inflate when either side of the
vehicle is struck. In addition, these
roof-rail airbags are designed to
inflate in a severe frontal impact.
The roof-rail airbags are also
rollover capable except on models
sold as an incomplete vehicle with
the pickup box removed. If the
roof-rail airbags are rollover
capable, both roof-rail airbags will
also inflate if the sensing system
predicts that the vehicle is about to
roll over on its side. The roof-rail
airbags are not designed to inflate in
rear impacts.
Vehicles with a GVWR above
4 536 kg (10,000 lb) may or may not
be equipped with roof-rail airbags.
These roof-rail airbags, if equipped,are designed to inflate in moderate
to severe side crashes depending
on the location of the impact. Both
roof-rail airbags will inflate when
either side of the vehicle is struck.
In addition, these roof-rail airbags
are designed to inflate in a severe
frontal impact. If the vehicle has
single rear wheels and has a
factory-installed pickup box and
roof-rail airbags, the roof-rail airbags
are rollover capable. If the vehicle
has dual rear wheels, or is sold as
an incomplete vehicle, as a chassis
cab, or with the pickup box
removed, and has roof-rail airbags,
the roof-rail airbags are not rollover
capable. If the airbags are rollover
capable, both roof-rail airbags will
also inflate if the sensing system
predicts that the vehicle is about to
roll over on its side. The roof-rail
airbags are not designed to inflate in
rear impacts.
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? 074.
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 safety belts by
distributing the force of the impact
more evenly over the
occupant's body.

{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 0485 andEvent Data
Recorders 0486.
. 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 passenger side instrument
panel endcap has the switch
pictured in the following illustration,
the vehicle has an airbag on-off
switch that you can use to manually turn on or off the front outboard
passenger frontal airbag. See
Instrument Panel
06.
If the vehicle does not have an
airbag on-off switch, it may have a
passenger sensing system. See
Passenger Sensing System 081.
This switch should only be turned to
the off position if the person in the
front outboard passenger position is
a member of a passenger risk group
identified by the national
government as follows:
Infant. An infant (less than 1 year
old) must ride in the front seat
because:
. My vehicle has no rear seat;

Mexico-9955992) - 2017 - crc - 4/18/17
80 Seats and Restraints
.My vehicle has a rear seat too
small to accommodate a
rear-facing infant seat; or
. The infant has a medical
condition which, according to the
infant's physician, makes it
necessary for the infant to ride in
the front seat so that the driver
can constantly monitor the
child's condition.
Child age 1 to 12. A child
age 1 to 12 must ride in the front
seat because:
. My vehicle has no rear seat;
. Although children ages 1 to 12
ride in the rear seat(s) whenever
possible, children ages 1 to 12
sometimes must ride in the front
because no space is available in
the rear seat(s) of my vehicle; or
. The child has a medical
condition which, according to the
child's physician, makes it
necessary for the child to ride in
the front seat so that the driver
can constantly monitor the
child's condition. Medical Condition. A passenger
has a medical condition which,
according to his or her physician:
.
Causes the passenger airbag to
pose a special risk for the
passenger; and
. Makes the potential harm from
the passenger airbag in a crash
greater than the potential harm
from turning off the airbag and
allowing the passenger, even if
belted, to hit the instrument
panel or windshield in a crash.
{Warning
If the front outboard passenger
frontal airbag is turned off for a
person who is not in a risk group
identified by the national
government, that person will not
have the extra protection of an
airbag. In a crash, the airbag will
not be able to inflate and help
protect the person sitting there.

you know that the front outboard
passenger frontal airbag is off. See
Airbag On-Off Light0141. The front
outboard passenger airbag will
remain off until you turn it back on
again.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. For
example, the front outboard
passenger frontal airbag could
inflate even though the airbag
on-off switch is turned off.
To help avoid injury to yourself or
others, have the vehicle serviced
right away. See Airbag Readiness
Light 0141 for more information,
including important safety
information.To turn the front outboard passenger
frontal airbag on again, insert the
ignition key into the switch, push in,
and move the switch to the on
position.
The front outboard passenger
frontal airbag is now enabled
(may inflate). See Airbag On-Off
Light 0141.
Passenger Sensing
System
If the vehicle has one of the
following indicators, then the vehicle
has a passenger sensing system for
the front outboard passenger
position, unless there is an airbag
on-off switch on the instrument
panel endcap. If there is an airbag
on-off switch, the vehicle does not have a passenger sensing system.
See
Airbag On-Off Switch 079 for
more information.
The passenger airbag status
indicator will light on the overhead
console when the vehicle is started.
United States

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 any
parts of the front seats, safety belts,
the airbag sensing and diagnostic
module, steering wheel, instrument
panel, any of the airbag modules,
ceiling headliner or pillar garnish
trim, overhead console, front
sensors, side impact sensors,
or airbag wiring.Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
In addition, the vehicle may have a
passenger sensing system for the
front outboard passenger position,
which includes sensors that are part
of the passenger seat. The
passenger sensing system may not
operate properly if the original seat
trim is replaced with non-GM
covers, upholstery, or trim; or with
GM covers, upholstery, or trim
designed for a different vehicle. Any
object, such as an aftermarket seat
heater or a comfort-enhancing pad
or device, installed under or on top
of the seat fabric, could also
interfere with the operation of the
passenger sensing system. This
could either prevent proper
deployment of the passenger
airbag(s) or prevent the passenger
sensing system from properly
turning off the passenger airbag(s).
See
Passenger Sensing System
0 81. If the vehicle has rollover roof-rail
airbags, see
Different Size Tires
and Wheels 0419 for additional
important information.
If a snow plow is added to the
vehicle, the airbags should still work
properly. The airbag systems were
designed to work properly under a
wide range of conditions, including
snow plowing with vehicles that
have the optional snow plow prep
package (RPO VYU). Do not
change or defeat the snow plow's
“tripping mechanism.” If you do, it
can damage the snow plow and the
vehicle, and may cause an airbag
deployment.
If you have to modify your vehicle
because you have a disability and
you 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.

Seats and Restraints 93
When securing an add-on child
restraint, refer to the instructions
that come with the restraint which
may be on the restraint itself or in a
booklet, or both, and to this manual.
The child restraint instructions are
important, so if they are not
available, obtain a replacement
copy from the manufacturer.
Keep in mind that an unsecured
child restraint can move around in a
collision or sudden stop and injure
people in the vehicle. Be sure to
properly secure any child restraint in
the vehicle—even when no child is
in it.
In some areas of the United States
and Canada, Certified Child
Passenger Safety Technicians
(CPSTs) are available to inspect
and demonstrate how to correctly
use and install child restraints. In
the U.S., refer to the National
Highway Traffic Safety
Administration (NHTSA) website to
locate the nearest child safety seat
inspection station. For CPST
availability in Canada, check with
Transport Canada or the Provincial
Ministry of Transportation office.Securing the Child Within the
Child Restraint
{Warning
A child can be seriously injured or
killed in a crash if the child is not
properly secured in the child
restraint. Secure the child
properly following the instructions
that came with that child restraint.
Where to Put the
Restraint
According to accident statistics,
children and infants are safer when
properly restrained in an appropriate
child restraint secured in a rear
seating position.
Whenever possible, children aged
12 and under should be secured in
a rear seating position.
If a child restraint is secured in the
front outboard passenger seat, and
the vehicle has a switch on the
passenger side instrument panel
endcap to manually turn off the front outboard passenger airbag, see
Airbag On-Off Switch
079 and

Seat) 0106 orSecuring Child
Restraints (With the Safety Belt in
the Front Passenger Seat) 0110 for
more information, including
important safety information.
Never put a rear-facing child seat in
the front. This is because the risk to
the rear-facing child is so great,
if the airbag deploys.{Warning
A child in a rear-facing child
restraint can be seriously injured
or killed if the front outboard
passenger frontal airbag inflates.
This is because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the front

7. If the vehicle does not have arear seat and the child restraint
manufacturer recommends
using a top tether anchor,
attach the top tether to the top
tether anchor. Refer to the
instructions that came with the
child restraint and to Lower
Anchors and Tethers for
Children (LATCH System) 095.
8. Before placing a child in the child restraint, make sure it is
securely held in place. To
check, grasp the child restraint
at the safety belt path and
attempt to move it side to side
and back and forth. When the
child restraint is properly
installed, there should be no
more than 2.5 cm (1 in) of
movement.
If the vehicle is equipped with a
passenger sensing system, and
when the passenger sensing system
has turned off the front outboard
passenger frontal airbag, the off
indicator in the passenger airbag
status indicator should light and stay
lit when the vehicle is started. If a child restraint has been installed
and the on indicator is lit, see
“If the
On Indicator Is Lit for a Child
Restraint” underPassenger Sensing
System 081 for more information.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it.
With Airbag On-Off Switch
This vehicle has airbags. A rear
seat is a safer place to secure a
forward-facing child restraint. See
Where to Put the Restraint 093.
There may be a switch on the
instrument panel endcap that you
can use to turn off the front
outboard passenger frontal airbag.
See Airbag On-Off Switch 079 for
more information, including
important safety information.
Never put a rear-facing child seat in
the front. This is because the risk to
the rear-facing child is so great,
if the airbag deploys.
{Warning
A child in a rear-facing child
restraint can be seriously injured
or killed if the front outboard
passenger airbag inflates. This is
because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the front
outboard passenger airbag
inflates and the passenger seat is
in a forward position.
Even if the airbag switch has
turned off the front outboard
passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though it is
turned off.
