to detect that person and enable the
front outboard passenger frontal
airbag:1. Turn the vehicle off.
2. Remove any additional material from the seat, such as
blankets, cushions, seat
covers, seat heaters, or seat
massagers.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat, centered on the seat
cushion, with legs comfortably
extended.
5. Restart the vehicle and have the person remain in this
position for two to
three minutes after the off
indicator is not lit.
{Warning
If the front outboard passenger
airbag is turned off for an
adult-sized occupant, the airbag
(Continued)
Warning (Continued)
will not be able to inflate and help
protect that person in a crash,
resulting in an increased risk of
serious injury or even death. An
adult-sized occupant should not
ride in the front outboard
passenger seat, if the passenger
airbag off indicator is lit.
Additional Factors Affecting
System Operation
Seat 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“Seat 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 063
for more information about
modifications that can affect how
the system operates.
{Warning
Stowing articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
{Warning

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
Service Publications Ordering
Information 0272.
{Warning
For up to three minutes 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
any parts of the front seats, seat
belts, airbag sensing and diagnostic
module, steering wheel, instrument
panel, inner door seals including the
speakers, any of the airbag
modules, ceiling or pillar garnish
trim, 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 has 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 notoperate 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 56.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires
and Wheels 0216 for additional
important information.
If you have to modify your vehicle
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
0265.
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 089.
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? 051. See your dealer

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 089.
Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the
vehicle’s seat belts.
The manufacturer ’s 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, 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.

11683523) - 2018 - CRC - 7/10/17
Seats and Restraints 65
It should never be worn over the
abdomen, which could cause
severe or even fatal internal
injuries in a crash.
According to accident statistics,
children are safer when properly
restrained in a rear seating position.
In a crash, children who are not
buckled up can strike other people
who are buckled up, or can be
thrown out of the vehicle. Older
children need to use seat belts
properly.
{Warning
Never allow more than one child
to wear the same seat belt. The
seat belt cannot properly spread
the impact forces. In a crash, they
can be crushed together and
seriously injured. A seat belt must
be used by only one person at
a time.
{Warning
Never allow a child to wear the
seat belt with the shoulder belt
behind their back. A child can be
seriously injured by not wearing
the lap-shoulder belt properly. In a
crash, the child would not be
restrained by the shoulder belt.
The child could move too far
forward increasing the chance of
head and neck injury. The child
might also slide under the lap
belt. The belt force would then be
applied right on the abdomen. (Continued)
Warning (Continued)
That could cause serious or fatal
injuries. The shoulder belt should
go over the shoulder and across
the chest.
Infants and Young
Children
Everyone in a vehicle needs
protection! This includes infants and
all other children. Neither the
distance traveled nor the age and
size of the traveler changes the

Chevrolet City Express Owner Manual (GMNA-Localizing-U.S./Canada-
11683523) - 2018 - CRC - 7/10/17
66 Seats and Restraints
need, for everyone, to use safety
restraints. In fact, the law in every
state in the United States and in
every Canadian province says
children up to some age must be
restrained while in a vehicle.
{Warning
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor,
but it cannot do this if it is
wrapped around a child’s neck.
If the shoulder belt is locked and
tightened around a child’s neck,
the only way to loosen the belt is
to cut it.(Continued)
Warning (Continued)
Never leave children unattended
in a vehicle and never allow
children to play with the seat
belts.
Every time infants and young
children ride in vehicles, they should
have the protection provided by
appropriate child restraints. Neither
the vehicle's seat belt system nor its
airbag system is designed for them.
Children who are not restrained
properly can strike other people,
or can be thrown out of the vehicle.
{Warning
Never hold an infant or a child
while riding in a vehicle. Due to
crash forces, an infant or a child
will become so heavy it is not
possible to hold it during a crash.
For example, in a crash at only
40 km/h (25 mph), a 5.5 kg (12 lb) (Continued)
Warning (Continued)
infant will suddenly become a
110 kg (240 lb) force on a person's
arms. An infant or child should be
secured in an appropriate
restraint.
{Warning
Children who are up against,
or very close to, any airbag when
it inflates can be seriously injured(Continued)

Warning (Continued)
or killed. Never put a rear-facing
child restraint in the front
outboard seat. If you must secure
a forward-facing child restraint in
the front outboard seat, always
move the front passenger seat as
far back as it will go.
Child restraints are devices used to
restrain, seat, or position children in
the vehicle and are sometimes
called child seats or car seats.There are three basic types of
child restraints:
.
Forward-facing child restraints
. Rearward-facing child restraints
. Belt-positioning booster seats
The proper child restraint for your
child depends on their size, weight,
and age, and also on whether the
child restraint is compatible with the
vehicle in which it will be used.
For each type of child restraint,
there are many different models
available. When purchasing a child
restraint, be sure it is designed to be
used in a motor vehicle. If it is, the
restraint will have a label saying that
it meets federal motor vehicle safety
standards. The restraint
manufacturer's instructions that
come with the restraint state the
weight and height limitations for a
particular child restraint. In addition,
there are many kinds of restraints
available for children with special
needs.
{Warning
To reduce the risk of neck and
head injury in a crash, infants and
toddlers should be secured in a
rear-facing child restraint until age
two, or until they reach the
maximum height and weight limits
of their child restraint.
{Warning
A young child's hip bones are still
so small that the vehicle's regular
seat belt may not remain low on
the hip bones, as it should.
Instead, it may settle up around
the child's abdomen. In a crash,
the belt would apply force on a
body area that is unprotected by
any bony structure. This alone
could cause serious or fatal
injuries. To reduce the risk of
serious or fatal injuries during a (Continued)

crash, young children should
always be secured in appropriate
child restraints.
Child Restraint Systems
Rear-Facing Infant Restraint
A rear-facing child restraint provides
restraint with the seating surface
against the back of the infant.
The harness system holds the infant
in place and, in a crash, acts to
keep the infant positioned in the
restraint.
Forward-Facing Child Restraint
A forward-facing child restraint
provides restraint for the child's
body with the harness.Booster Seats
{Warning
If a booster seat and seat belt are
not used properly, the risk of a
child being injured in a sudden
stop or collision greatly increases: . Make sure the shoulder
portion of the belt is away
from the child’s face and
neck and the lap portion of
the belt does not cross the
stomach.

Warning (Continued)
.Make sure the shoulder belt
is not behind the child or
under the child’s arm.
. A booster seat must only be
installed in a seating
position that has a lap/
shoulder belt.
A belt positioning booster seat is
used for children who have
outgrown their forward facing child
restraint. Boosters are designed to
improve the fit of the vehicle's seat
belt system until the child is large
enough for the vehicle seat belts to
fit properly without a booster seat.
See the seat belt fit test in Older
Children 064.
Booster seats of various sizes are
offered by several manufacturers.
When selecting any booster seat,
keep the following points in mind:
. Choose only a booster seat with
a label certifying that it complies
with Federal Motor Vehicle Safety Standard 213 or
Canadian Motor Vehicle Safety
Standard 213.
. Check the booster seat in your
vehicle to be sure it is
compatible with the vehicle’ s
seat and seat belt system.
. Make sure the child’s head will
be properly supported by the
booster seat or vehicle seat. The
seatback must be at or above
the center of the child’s ears. For
example, if a low back booster
seat is chosen, the vehicle
seatback must be at or above
the center of the child’s ears.
If the seatback is lower than the
center of the child’s ears, a high
back booster seat should
be used.
. If the booster seat is compatible
with your vehicle, place the child
in the booster seat and check
the various adjustments to be
sure the booster seat is
compatible with the child.
Always follow all recommended
procedures. All U.S. states and Canadian
provinces or territories require that
infants and small children be
restrained in an approved child
restraint at all times while the
vehicle is being operated.
The instructions in this section apply
to booster seat installation in the
front passenger seat. See
“Securing
a Booster Seat” underSecuring
Child Restraints 075.
Securing an Add-On Child
Restraint in the Vehicle
{Warning
A child can be seriously injured or
killed in a crash if the child
restraint is not properly secured in
the vehicle. Secure the child
restraint properly in the vehicle
using the vehicle’s seat belt or
LATCH system, following the
instructions that came with that
child restraint and the instructions
in this manual.
