Memory Seats
Overview
If equipped, the memory seat feature allows
drivers to save their unique driving positions
and a shared exit position. See“Saving
Seating Positions” later in this section. The
saved positions can be recalled manually by
all drivers, see “Manually Recalling Seating
Positions” later in this section, and drivers
with remote key 1 and 2 can also recall
them automatically. See “Auto Seat Entry
Memory Recall” or“Auto Seat Exit Memory
Recall” later in this section. To enable
automatic recalls, turn on Seat Entry
Memory and/or Seat Exit Memory. See
“Enabling Automatic Recalls” later in thissection. The memory recalls may be
canceled at any time during the recall. See
“Cancel Memory Seating Recalls”
later in this
section.
Identifying Driver Number
The vehicle identifies the current driver by
their remote key number 1–8. The current
remote key number may be identified by
Driver Information Center (DIC) welcome
message, “You are driver x for memory
recalls.” This message is displayed the first
few times the vehicle is turned on when a
different remote key is used. For Seat Entry
Memory to work properly, save positions to
the 1 or 2 memory button matching the
driver number of this welcome message. To
aid in identifying remote key IDs, it is
recommended to only carry one remote key
when entering the vehicle. Perform the
following if the welcome message is not
displayed:
1. Move all keys and remote keys away from the vehicle.
2. Start the vehicle with another remote key. A DIC welcome message should
display indicating the driver number of
the other remote key. Turn the vehicle
off and remove the other key or remote
key from the vehicle. 3. Start the vehicle with the initial key or
remote key. The DIC welcome message
should display the driver number of the
initial remote key.
Saving Seating Positions
Read these instructions completely before
saving memory positions.
To save preferred driving positions to
1 and 2: 1. Turn the vehicle on or to accessory mode. A DIC welcome message may
indicate the driver number of the current
remote key. See “Identifying Driver
Number” previously in this section.
2. Adjust all available memory features to the desired driving position.
3. Press and release SET; a beep will sound.
4. Immediately upon releasing SET, press and hold memory button 1 or 2 matching
the current Driver’s remote key number
until two beeps sound. If too much time
passes between releasing SET and
pressing 1 or 2, the two beeps will not
sound indicating memory position were
not saved. Repeat Steps 3 and 4 to try
again.

Questions and Answers About Seat Belts
Q: Will I be trapped in the vehicle after acrash if I am wearing a seat belt?
A: You could be— whether you are
wearing a seat belt or not. Your chance
of being conscious during and after a
crash, so you canunbuckle and get out,
is much greater if you are belted.
Q: If my vehicle has airbags, why should I have to wear seat belts?
A: Airbags are supplemental systems only.
They work withseat belts —not instead
of them. Whether or not an airbag is
provided, all occupants still have to
buckle up to get the most protection.
Also, in nearly all states and in all
Canadian provinces, the law requires
wearing seat belts.
Buckle To Drive
If equipped, this feature delays the vehicle
from shifting out of P (Park) when the driver
seat belt is not buckled. The Buckle to Drive
feature must be turned ON in the
infotainment system to work. To turn the
Buckle to Drive feature on or off, select
Settings > Vehicle > Buckle to Drive. See
Teen Driver 0179, if equipped. If the vehicle is on and the brake pedal is
pressed with the vehicle in P (Park) but the
driver seat belt is not buckled, a message
displays in the Driver Information
Center (DIC) and the vehicle will be delayed
from shifting out of P (Park). Buckle the
driver seat belt to clear the message and
shift out of P (Park). Shifting from P (Park)
will be delayed once for each time the
vehicle is started.
For some fleet vehicles, the feature is
always ON and cannot be turned OFF in the
infotainment system. The vehicle will be
delayed from shifting from P (Park) each
time the driver attempts to do so while the
driver seat belt is not buckled. Turning the
vehicle off then on will not change this
condition.
On some models, Buckle to Drive may also
delay shifting out of P (Park) if a front
passenger seat belt is unbuckled. A message
displays in the DIC. Buckle the front
passenger seat belt to shift out of P (Park).
This feature may delay the vehicle from
shifting out of P (Park) if an object, such as
a briefcase, handbag, grocery bag, laptop,
or other electronic device, is on the front
passenger seat. If this happens, remove the
object from the seat or buckle the seat belt
to shift out of P (Park).
If the driver, or on some vehicles, the
present front passenger remains unbuckled,
the DIC message will turn off after several
seconds and the vehicle can be shifted out
of P (Park). See
“Seat Belts”and“Child
Restraints” in the Index for information
about the importance of proper
restraint use.
If the driver seat belt or the front passenger
seat belt is unbuckled when driving, the seat
belt reminder chime and light(s) will come
on. See Seat Belt Reminders 0114. This
feature may not function properly if the
airbag readiness light is on. See Airbag
Readiness Light 0115.
How to Wear Seat Belts Properly
Follow these rules for everyone's protection.
There are additional things to know about
seat belts and children, including smaller
children and infants. If a child will be riding
in the vehicle, see Older Children070 or
Infants and Young Children 071. Review and
follow the rules for children in addition to
the following rules.

The roof-rail airbags for the driver, front
outboard passenger, and second 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 (Continued)
Warning (Continued)
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. See
Airbag System059. 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 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.
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

Chevrolet Silverado 1500 Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico/Paraguay-16515119) - 2023 - CRC - 6/2/22
Seats and Restraints 63
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.
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 may inflate during a
rollover or in a severe frontal impact.
Roof-rail airbags are not designed to inflate
in rear impacts. Both roof-rail airbags may
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,
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
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? 061.
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 and second 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?
0 62. 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. 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? 061.
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
windshield or being able to steer the
vehicle, nor does it prevent people from
leaving the vehicle.

{Warning
When an airbag inflates, there may be
dust in the air. This dust could cause
breathing problems for people with a
history of asthma or other breathing
trouble. To avoid this, everyone in the
vehicle should get out as soon as it is
safe to do so. If you have breathing
problems but cannot get out of the
vehicle after an airbag inflates, then get
fresh air by opening a window or a door.
If you experience breathing problems
following an airbag deployment, you
should seek medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn on the
interior lamps and hazard warning flashers,
and shut off the fuel system after the
airbags inflate. The feature may also
activate, without airbag inflation, after an
event that exceeds a predetermined
threshold. After turning the ignition off and
then on again, the fuel system will return to
normal operation; the 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 0439 and
Event Data Recorders 0440.
.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.
Passenger Sensing System
The vehicle has a passenger sensing system
for the front outboard passenger position.
The passenger airbag status indicator will
light on the overhead console when the
vehicle is started.

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) 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
child restraint.

outboard seat. Secure a rear-facing child
restraint in a rear seat. It is also better to
secure a forward-facing child restraint in
a rear 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
.Rear-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 and
is designed by a genuine child restraint
manufacturer. If it is, the child restraint will
have a label saying that it meets federal
motor vehicle safety standards.
The instruction manual that is provided with
the child restraint states the weight and
height limitations for that particular child
restraint. In addition, there are many kinds
of child 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 (Continued)

If the child restraint manufacturer
recommends that the top tether be
attached, adjust the top tether to its full
length and attach it to the anchor. Refer
to the child restraint instructions and the
following steps:
1.1. Find the top tether anchor.
1.2. Route, attach, and tighten the top tether according to your child
restraint instructions and the
following instructions:If the position you are using has an
adjustable headrest or head
restraint, adjust it accordingly to
allow proper fitment. If you are
using a dual tether, route the
tether around the headrest or head
restraint posts.
If the child restraint is installed next
to a center seat, make sure the top
tether does not interfere with the
center seating position shoulder
belt/retractor. If it does, find
another suitable seating position to
install the child restraint.
If the position you are using has an
adjustable headrest or head
restraint, adjust it accordingly to
allow proper fitment. If you are using a single tether, route the
tether in between the headrest or
head restraint posts.
2. Make sure the child restraint top tether hook is completely closed and secured to
the top tether anchor.
3. Secure the child restraint in the right front seating position with the vehicle
belts. See Securing Child Restraints (With
