Tailgate
WARNING
{
It is extremely dangerous to ride
on the tailgate, even when the
vehicle is operated at low speeds.
People riding on the tailgate
can easily lose their balance and
fall in response to vehicle
maneuvers. Falling from a moving
vehicle may result in serious
injuries or death. Do not allow
people to ride on the tailgate.
(Continued)
WARNING (Continued)
Be sure everyone in your vehicle
is in a seat and using a safety
belt properly.
Use the Remote Keyless
Entry (RKE) transmitter or power
door lock switch to lock and unlock
the tailgate.

Vehicle Security
This vehicle has theft-deterrent
features; however, they do not make
it impossible to steal.
Anti-Theft Alarm System
Your vehicle has a content
theft-deterrent alarm system.
This is the security light.
To arm the theft-deterrent system:
1. Open the door.
2. Lock the door with the Remote
Keyless Entry (RKE) transmitter
or the power door lock switch.
The security light will come on to
inform the driver the system is
arming. If a door is open when
the doors are locked, the
security light will flash.
If the delayed locking feature is
turned on, the theft‐deterrent
system will not start the arming
process until the last door is
closed and the delay timer has
expired. See Delayed Lockingon page 2‑8.
3. Close all doors. The security
light should go off after about
30 seconds. The alarm is not
armed until the security light
goes off.
The content theft deterrent
system does not sense if the
midgate or tailgate are open or
ajar, therefore, vehicle contents
may not be protected if the
midgate is left open or ajar.
If a locked driver door is opened
without using the RKE transmitter,
a ten second pre-alarm will occur.
The horn will chirp and the lights will
flash. If the key is not placed in the
ignition and turned to START or the
door is not unlocked by pressing
the unlock button on the RKE
transmitter during the ten second
pre-alarm, the alarm will go off. Your
vehicle's headlamps will flash and
the horn will sound for about
30 seconds, then will turn off to
save the battery power.
The theft-deterrent system will not
activate if the doors are locked with
the vehicle's key or the manual door
lock. It activates only if you use the
power door lock switch with the door
open or the RKE transmitter. You
should also remember that you can
start your vehicle with the correct
ignition key if the alarm has been
set off.
To avoid setting off the alarm by
accident:
.
If you do not want to activate the
theft-deterrent system, the
vehicle should be locked with
the door key after the doors are
closed.
.
Always unlock the doors with the
RKE transmitter. Unlocking a
door any other way will set off
the alarm if it is armed.
Page 54
Blackplate(18,1)
ChevroletAvalancheOwnerManual-2011
2-18Keys, Doors and Windows
If you set off the alarm by accident,
press unlock on the RKE transmitter
or place the key in the ignition and
turn it to START to turn off the
alarm. The alarm will not stop if you
try to unlock a door any other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, lower
the driver window and open the
driver door.
2. Activate the system by
locking the doors with the
power door lock switch while
the door is open, or with the
RKE transmitter.
3. Get out of the vehicle, close the
door and wait for the security
light to go out.
4. Then reach in through the
window, unlock the door with the
manual door lock and open the
door. This should set off the
alarm.
While the alarm is set, the power
door unlock switch will not work.
If the alarm does not sound when it
should but the headlamps flash,
check to see if the horn works. The
horn fuse may be blown. To replace
the fuse, see Instrument Panel Fuse
Block on page 10‑46 and Engine
Compartment Fuse Block on
page 10‑41.
If the alarm does not sound or the
headlamps do not flash, the vehicle
should be serviced by your dealer.

Immobilizer Operation
This vehicle has PASS-Key®III+
(Personalized Automotive Security
System) theft-deterrent system.
PASS-Key III+ is a passive
theft-deterrent system.
The system is automatically armed
when the key is removed from the
ignition.
The system is automatically
disarmed when the key is turned to
ON/RUN, ACC/ACCESSORY,
or START from the LOCK/OFF
position.
You do not have to manually arm or
disarm the system.
The security light will come on if
there is a problem with arming or
disarming the theft-deterrent
system.
When the PASS-Key III+ system
senses that someone is using
the wrong key, it prevents the
vehicle from starting.
Page 55
Blackplate(19,1)
ChevroletAvalancheOwnerManual-2011
Keys, Doors and Windows2-19
Anyone using a trial-and-error
method to start the vehicle will be
discouraged because of the high
number of electrical key codes.
If the engine does not start and the
security light on the instrument
panel cluster comes on when trying
to start the vehicle, there may be a
problem with the theft-deterrent
system. Turn the ignition off and
try again.
If the engine still does not start, and
the key appears to be undamaged,
try another ignition key. At this time,
you may also want to check the
fuse. See Fuses and CircuitBreakers on page 10‑41. If the
engine still does not start with the
other key, the vehicle needs service.
If the vehicle does start, the first key
may be faulty. See your dealer who
can service the PASS-Key III+ to
have a new key made.
It is possible for the PASS-Key III+
decoder to learn the transponder
value of a new or replacement key.
Up to 10 keys may be programmed
for the vehicle. The following
procedure is for programming
additional keys only. If all the
currently programmed keys are lost
or do not operate, you must see
your dealer or a locksmith who can
service PASS-Key III+ to have keys
made and programmed to the
system.
See your dealer or a locksmith who
can service PASS-Key III+ to get a
new key blank cut exactly as the
ignition key that operates the
system.
To program the new additional key:
1. Verify that the new key has a
stamped on it.
2. Insert the original, already
programmed key in the ignition
and start the engine. If the
engine will not start, see your
dealer for service.
3. After the engine has started, turn
the key to LOCK/OFF, and
remove the key.
1
4. Insert the new key to be
programmed and turn it to the
ON/RUN position within
five seconds of turning the
ignition to the LOCK/OFF
position in Step 3.
The security light will turn off
once the key has been
programmed.
5. Repeat Steps 1 through 4 if
additional keys are to be
programmed.
If you lose or damage your
PASS-Key III+ key, see your dealer
or a locksmith who can service
PASS-Key III+ to have a new
key made.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.

dangerous. Even when buckled
up, the safety belts cannot do
their job when reclined like this.
The shoulder belt cannot do its
job because it will not be against
your body. Instead, it will be in
front of you. In a crash, you
could go into it, receiving neck or
other injuries.
(Continued)
WARNING (Continued)
The lap belt cannot do its job
either. In a crash, the belt could
go up over your abdomen. The
belt forces would be there, not at
your pelvic bones. This could
cause serious internal injuries.
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear the
safety belt properly.
Do not have a seatback reclined if
the vehicle is moving.

Safety Belts
This section of the manual
describes how to use safety belts
properly. It also describes some
things not to do with safety belts.
WARNING
{
Do not let anyone ride where a
safety belt cannot be worn
properly. In a crash, if you or your
passenger(s) are not wearing
safety belts, the injuries can be
much worse. You can hit things
inside the vehicle harder or be
ejected from the vehicle. You and
your passenger(s) can be
seriously injured or killed. In the
same crash, you might not be,
if you are buckled up. Always
fasten your safety belt, and check
that your passenger(s) are
restrained properly too.
WARNING
{
People riding on the tailgate
(if equipped) can easily lose their
balance and fall even when the
vehicle is operated at low speeds.
Falling from a moving vehicle may
result in serious injuries or death.
WARNING
{
It is extremely dangerous to ride
in a cargo area, inside or outside
of a vehicle. In a collision, people
riding in these areas are more
likely to be seriously injured or
killed. Do not allow people to ride
in any area of your vehicle that is
not equipped with seats and
safety belts. Be sure everyone in
your vehicle is in a seat and using
a safety belt properly.
This vehicle has indicators as a
reminder to buckle the safety belts.
See Safety Belt Reminders onpage 5‑16 for additional information.
In most states and in all Canadian
provinces, the law requires wearing
safety belts. Here is why:
You never know if you will be in a
crash. If you do have a crash, you
do not know if it will be a
serious one.
A few crashes are mild, and some
crashes can be so serious that even
buckled up, a person would not
survive. But most crashes are in
between. In many of them, people
who buckle up can survive and
sometimes walk away. Without
safety belts they could have been
badly hurt or killed.
After more than 40 years of safety
belts in vehicles, the facts are clear.
In most crashes buckling up does
matter ... a lot!

Why Safety Belts Work
When you ride in or on anything,
you go as fast as it goes.
Seats and Restraints3-13
Take the simplest vehicle. Suppose
it is just a seat on wheels.
Put someone on it.Get it up to speed. Then stop the
vehicle. The rider does not stop.
Page 78
Blackplate(14,1)
ChevroletAvalancheOwnerManual-2011
3-14Seats and Restraints
The person keeps going until
stopped by something. In a real
vehicle, it could be the windshield...
or the instrument panel...or the safety belts!
With safety belts, you slow down as
the vehicle does. You get more time
to stop. You stop over more
distance, and your strongest bones
take the forces. That is why safety
belts make such good sense.

Questions and Answers About
Safety Belts
Q: Will I be trapped in the vehicle
after a crash if I am wearing a
safety belt?
A: You could be — whether you are
wearing a safety belt or not. But
your chance of being conscious
during and after an accident, so
you can unbuckle and get out, is
much greater if you are belted.
And you can unbuckle a safety
belt, even if you are
upside down.
Q: If my vehicle has airbags, why
should I have to wear safety
belts?
A: Airbags are supplemental
systems only; so they work with
safety belts — not instead of
them. Whether or not an airbag
is provided, all occupants still
have to buckle up to get the
most protection. That is true not
only in frontal collisions, but
especially in side and other
collisions.
Q: If I am a good driver, and
I never drive far from home,
why should I wear safety
belts?
A: You may be an excellent driver,
but if you are in a crash — even
one that is not your fault — you
and your passenger(s) can be
hurt. Being a good driver does
not protect you from things
beyond your control, such as
bad drivers.
Most accidents occur within
40 km (25 miles) of home. And
the greatest number of serious
injuries and deaths occur at
speeds of less than
65 km/h (40 mph).
Safety belts are for everyone.

How to Wear Safety Belts
Properly
This section is only for people of
adult size.
Be aware that there are special
things to know about safety belts
and children. And there are different
rules for smaller children and
infants. If a child will be riding in the
vehicle, see Older Children on
page 3‑46 or Infants and Young
Children on page 3‑48. Follow those
rules for everyone's protection.
It is very important for all occupants
to buckle up. Statistics show that
unbelted people are hurt more often
in crashes than those who are
wearing safety belts.
Occupants who are not buckled up
can be thrown out of the vehicle in a
crash. And they can strike others
in the vehicle who are wearing
safety belts.
First, before you or your
passenger(s) wear a safety belt,
there is important information you
should know.
Sit up straight and always keep
your feet on the floor in front of you.
The lap part of the belt should be
worn low and snug on the hips, just
touching the thighs. In a crash, this
applies force to the strong pelvic
bones and you would be less
likely to slide under the lap belt.
If you slid under it, the belt would
apply force on your abdomen. This
could cause serious or even fatal
injuries. The shoulder belt should go
over the shoulder and across the
chest. These parts of the body are
best able to take belt restraining
forces.
The shoulder belt locks if there is a
sudden stop or crash.

Q: What is wrong with this?
A: The shoulder belt is too loose.
It will not give as much
protection this way.
WARNING
{
You can be seriously hurt if your
shoulder belt is too loose. In a
crash, you would move forward
too much, which could increase
injury. The shoulder belt should fit
snugly against your body.
Q: What is wrong with this?
A: The lap belt is too loose. It will
not give nearly as much
protection this way.
WARNING
{
You can be seriously hurt if your
lap belt is too loose. In a crash,
you could slide under the lap belt
and apply force on your
abdomen. This could cause
serious or even fatal injuries.
The lap belt should be worn low
and snug on the hips, just
touching the thighs.

Q: What is wrong with this?
A: The belt is buckled in the
wrong buckle.
WARNING
{
You can be seriously injured if
your belt is buckled in the wrong
place like this. In a crash, the belt
would go up over your abdomen.
The belt forces would be there,
not on the pelvic bones. This
could cause serious internal
injuries. Always buckle your belt
into the buckle nearest you.
Q: What is wrong with this?
A: The belt is over an armrest.
Page 83
Blackplate(19,1)
ChevroletAvalancheOwnerManual-2011
Seats and Restraints3-19
WARNING
{
You can be seriously injured if
your belt goes over an armrest
like this. The belt would be much
too high. In a crash, you can slide
under the belt. The belt force
would then be applied on the
abdomen, not on the pelvic
bones, and that could cause
serious or fatal injuries. Be sure
the belt goes under the armrests.
Q: What is wrong with this?
A: The shoulder belt is worn under
the arm. It should be worn over
the shoulder at all times.
WARNING
{
You can be seriously injured if
you wear the shoulder belt under
your arm. In a crash, your body
would move too far forward,
which would increase the chance
of head and neck injury. Also, the
belt would apply too much force
to the ribs, which are not as
strong as shoulder bones.
You could also severely injure
internal organs like your liver or
spleen. The shoulder belt should
go over the shoulder and across
the chest.

Q: What is wrong with this?
A: The belt is behind the body.
WARNING
{
You can be seriously injured by
not wearing the lap-shoulder belt
properly. In a crash, you would
not be restrained by the shoulder
belt. Your body could move too
far forward increasing the chance
of head and neck injury. You
might also slide under the lap
belt. The belt force would then be
applied right on the abdomen.
That could cause serious or fatal
injuries. The shoulder belt should
go over the shoulder and across
the chest.
Q: What is wrong with this?
A: The belt is twisted across
the body.
Page 85
Blackplate(21,1)
ChevroletAvalancheOwnerManual-2011
Seats and Restraints3-21
WARNING
{
You can be seriously injured by a
twisted belt. In a crash, you would
not have the full width of the belt
to spread impact forces. If a belt
is twisted, make it straight so it
can work properly, or ask your
dealer to fix it.
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt except for
the center front passenger position
(if equipped), which has a lap belt.
See Lap Belt on page 3‑26 for more
information.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is
adjustable, so you can sit up
straight. To see how, see
“Seats” in the Index.
2. Pick up the latch plate and pull
the belt across you. Do not let it
get twisted.
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.
If the shoulder portion of a
passenger belt is pulled out all
the way, the child restraint
locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.
Engaging the child restraint
locking feature may affect the
passenger sensing system,
if equipped. See Passenger
Sensing System on page 3‑38
for more information.
If the belt stops before it reaches
the buckle, tilt the latch plate and
keep pulling the safety belt until
it can be buckled.

4. If equipped with a shoulder belt
height adjuster, move it to the
height that is right for you. See
“Shoulder Belt Height Adjuster”
in this section for instructions on
use and important safety
information.
3. Push the latch plate into the
buckle until it clicks. If you find
that the latch plate will not go
fully into the buckle, see if you
are using the correct buckle.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see SafetyBelt Extender on page 3‑27.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
5. To make the lap part tight, pull
up on the shoulder belt.
It may be necessary to pull
stitching on the safety belt
through the latch plate to fully
tighten the lap belt on smaller
occupants.
To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position.
Before a door is closed, be sure the
safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
belt and the vehicle.

Seats and Restraints3-23
Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
right front passenger positions.
Adjust the height so the shoulder
portion of the belt is on the shoulder
and not falling off of it. The belt
should be close to, but not
contacting, the neck. Improper
shoulder belt height adjustment
could reduce the effectiveness of
the safety belt in a crash. See How
to Wear Safety Belts Properly on
page 3‑16.
Squeeze the buttons (A) on the
sides of the height adjuster and
move the height adjuster to the
desired position.
The adjuster can be moved up
just by pushing up on the shoulder
belt guide.
After the adjuster is set to the
desired position, try to move it down
without squeezing the buttons to
make sure it has locked into
position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for front outboard
occupants. Although the safety belt
pretensioners cannot be seen, they
are part of the safety belt assembly.
They can help tighten the safety
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 side impact airbags,
safety belt pretensioners can help
tighten the safety belts in a side
crash or a rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash,
they will need to be replaced, and
probably other new parts for the
vehicle's safety belt system. See
Replacing Safety Belt System Parts
After a Crash on page 3‑28.

Rear Safety Belt Comfort
Guides
This vehicle may have rear shoulder
belt comfort guides. If not, they are
available through your dealer. The
guides may provide added safety
belt comfort for older children who
have outgrown booster seats and
for some adults. When installed and
properly adjusted, the comfort guide
positions the belt away from the
neck and head.
There is one guide, if equipped, for
each outside passenger position in
the rear seat. Here is how to install
a comfort guide to the safety belt:
1. Remove the guide from its
storage pocket on the side of
the seat.
2. Place the guide over the belt,
and insert the two edges of the
belt into the slots of the guide.

Safety Belt Use During
Pregnancy
Safety belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to
be seriously injured if they do not
wear safety belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.
The best way to protect the fetus is
to protect the mother. When a safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
Lap Belt
This part is only for the lap belt.
To learn how to wear a lap-shoulder
belt, see Lap-Shoulder Belt onpage 3‑21.
The vehicle may have a center
seating position. When you sit in the
center front seating position, you
have a lap safety belt, which has no
retractor.
To make the belt longer, tilt the latch
plate and pull it along the belt.
Buckle, position and release it the
same way as the lap part of a
lap-shoulder belt.
Page 91
Blackplate(27,1)
ChevroletAvalancheOwnerManual-2011
Seats and Restraints3-27
To make the belt shorter, pull its free
end as shown until the belt is snug.
If the belt is not long enough, see
Safety Belt Extender on page 3‑27.
Make sure the release button on the
buckle is positioned so you would
be able to unbuckle the safety belt
quickly if necessary.
If you find that the latch plate will
not go fully into the buckle, see if
you are using the correct buckle. Be
sure that the latch plate clicks when
inserted into the buckle.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety belt is not long
enough, your dealer will order you
an extender. When you go in to
order it, take the heaviest coat you
will wear, so the extender will be
long enough for you. To help avoid
personal injury, do not let someone
else use it, and use it only for the
seat it is made to fit. The extender
has been designed for adults. Never
use it for securing child seats. To
wear it, attach it to the regular safety
belt. For more information, see the
instruction sheet that comes with
the extender.
Safety System Check
Now and then, check that the safety
belt reminder light, safety belts,
buckles, latch plates, retractors, and
anchorages are working properly.
Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
from doing its job. See your dealer
to have it repaired. Torn or frayed
safety belts may not protect you in a
crash. They can rip apart under
impact forces. If a belt is torn or
frayed, get a new one right away.
Make sure the safety belt reminder
light is working. See Safety BeltReminders on page 5‑16 for more
information.
Keep safety belts clean and dry.
See Safety Belt Care on page 3‑27.
Safety Belt Care
Keep belts clean and dry.
WARNING
{
Do not bleach or dye safety belts.
It may severely weaken them. In
a crash, they might not be able to
provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.

Replacing Safety Belt
System Parts After a
Crash
WARNING
{
A crash can damage the safety
belt system in the vehicle.
A damaged safety belt system
may not properly protect the
person using it, resulting in
serious injury or even death in a
crash. To help make sure the
safety belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon
as possible.
After a minor crash, replacement of
safety belts may not be necessary.
But the safety belt assemblies that
were used during any crash may
have been stressed or damaged.
See your dealer to have the safety
belt assemblies inspected or
replaced.
New parts and repairs may be
necessary even if the safety belt
system was not being used at the
time of the crash.
Have the safety 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. See AirbagReadiness Light on page 5‑18.
Airbag System
The vehicle has the following
airbags:
.
A frontal airbag for the driver.
.
A frontal airbag for the right front
passenger.
.
A seat‐mounted side impact
airbag for the driver.
.
A seat‐mounted side impact
airbag for the right front
passenger.
.
A roof-rail airbag for the driver
and passenger directly behind
the driver.
.
A roof-rail airbag for the right
front passenger and passenger
seated directly behind the right
front passenger.
All of the airbags in the vehicle will
have the word AIRBAG embossed
in the trim or on an attached label
near the deployment opening.
Page 93
Blackplate(29,1)
ChevroletAvalancheOwnerManual-2011
Seats and Restraints3-29
For frontal airbags, the word
AIRBAG will appear on the middle
part of the steering wheel for the
driver and on the instrument panel
for the right front passenger.
With seat‐mounted side impact
airbags, the word AIRBAG will
appear on the side of the seatback
closest to the door.
With roof-rail airbags, the word
AIRBAG will appear along the
headliner or trim.
Airbags are designed to supplement
the protection provided by safety
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:
WARNING
{
You can be severely injured or
killed in a crash if you are not
wearing your safety belt — even if
you have airbags. Airbags are
designed to work with safety
belts, but do not replace them.
Also, airbags are not designed to
deploy in every crash. In some
crashes safety belts are your only
restraint. See When Should anAirbag Inflate? on page 3‑33.
Wearing your safety 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 safety belts. Everyone in your
vehicle should wear a safety belt
properly — whether or not there is
an airbag for that person.
WARNING
{
Airbags inflate with great force,
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 the airbag, as you would
be if you were sitting on the edge
of the seat or leaning forward.
Safety belts help keep you in
position before and during a
crash. Always wear a safety belt,
even with airbags. The driver
should sit as far back as possible
while still maintaining control of

WARNING
{
Children who are up against,
or very close to, any airbag when
it inflates can be seriously injured
or killed. Airbags plus
lap-shoulder belts offer protection
for adults and older children, but
not for young children and infants.
Neither the vehicle's safety belt
system nor its airbag system is

designed for them. Young
children and infants need the
protection that a child restraint
system can provide. Always
secure children properly in your
vehicle. To read how, see Older
Children on page 3‑46 or Infants
and Young Children on
page 3‑48.
There is an airbag readiness light
on the instrument panel cluster,
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 AirbagReadiness Light on page 5‑18 for

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 do not attach or put
anything on the steering wheel
hub or on or near any other
airbag covering.

WARNING (Continued)
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?
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 right
front passenger's head and chest.
However, they are only designed to
inflate if the impact exceeds a
predetermined 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.
Whether the frontal airbags will or
should deploy is not based on how
fast your vehicle is traveling.
It depends largely on what you hit,
the direction of the impact, and how
quickly your vehicle slows down.
Frontal airbags may inflate at
different crash speeds.
For example:
.
If the vehicle hits a stationary
object, the airbags could inflate
at a different crash speed than if
the vehicle hits a moving object.
.
If the vehicle hits an object that
deforms, the airbags could
inflate at a different crash speed
than if the vehicle hits an object
does not deform.
.
If the vehicle hits a narrow object
(like a pole), the airbags could
inflate at a different crash speed
than if the vehicle hits a wide
object (like a wall).
.
If the vehicle goes into an object
at an angle, the airbags could
inflate at a different crash speed
than if the vehicle goes straight
into the object.
Thresholds can also vary with
specific vehicle design.
Frontal airbags are not intended to
inflate during vehicle rollovers, rear
impacts, or in many side impacts.
In addition, the vehicle has
dual-stage frontal airbags.
Dual-stage airbags adjust the
restraint according to crash severity.
The vehicle has electronic frontal
sensors, which help the sensing
system distinguish between a
moderate frontal impact and a more
severe frontal impact. For moderate
frontal impacts, dual-stage airbags
inflate at a level less than full
deployment. For more severe frontal
impacts, full deployment occurs.
The vehicle has a seat position
sensor. Vehicles with dual stage
airbags also have seat position
sensors which enable the sensing
system to monitor the position of the
driver seat and the right front
passenger seat.
The seat position sensor provides
information that is used to determine
if the airbags should deploy at a
reduced level or at full deployment.

The vehicle has seat‐mounted side
impact and roof-rail airbags.
See Airbag System on page 3‑28.
Seat‐mounted side impact and
roof-rail airbags are intended to
inflate in moderate to severe side
crashes. In addition, these roof-rail
airbags are intended to inflate
during a rollover or in a severe
frontal impact. Seat‐mounted side
impact and roof-rail airbags will
inflate if the crash severity is above
the system's designed threshold
level. The threshold level can vary
with specific vehicle design.
Roof-rail airbags are not intended
to inflate in rear impacts.
A seat‐mounted side impact airbag
is intended to deploy on the side of
the vehicle that is struck. Both
roof-rail airbags will deploy when
either side of the vehicle is struck or
if the sensing system predicts that
the vehicle is about to roll over, or in
a severe frontal impact.
In any particular crash, no one can
say whether an airbag should have
inflated simply because of the
damage to a vehicle or because of
what the repair costs were.
For frontal airbags, inflation is
determined by what the vehicle hits,
the angle of the impact, and how
quickly the vehicle slows down.
For seat‐mounted side impact and
roof-rail airbags, deployment is
determined by the location and
severity of the side impact. In a
rollover event, roof-rail airbag
deployment is determined by the
direction of the roll.

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 and deploy. The inflator,
the airbag, and related hardware are
all part of the airbag module.
Frontal airbag modules are located
inside the steering wheel and
instrument panel. For vehicles with
seat‐mounted side impact airbags,
there are airbags modules in the
side of the front seatbacks closest
to the door. For vehicles with
roof-rail airbags, there are airbag
modules in the ceiling of the vehicle,
near the side windows that have
occupant seating positions.
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. Frontal
airbags distribute the force of the
impact more evenly over the
occupant's upper body, stopping
the occupant more gradually.
Seat‐mounted side impact and
roof-rail airbags distribute the force
of the impact more evenly over the
occupant's upper 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? on
page 3‑33 for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.

What Will You See After
an Airbag Inflates?
After the frontal airbags and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may not
even realize an airbag inflated.
Roof-rail airbags may still be at least
partially inflated for some time after
they deploy. Some components of
the airbag module may be hot for
several minutes. For location of the
airbag modules, see What Makesan Airbag Inflate? on page 3‑35.
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 may have 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. You can lock the
doors, turn off the interior lamps and
hazard warning flashers by using
the controls for those features.
