6. To tighten the belt, push down on the child restraint,
pull the shoulder belt to tighten the lap belt portion
and feed the shoulder belt back into the retractor.
If you are using a forward-facing child restraint, you
may nd it helpful to use your knee to push
down on the child restraint as you tighten the belt.
You should not be able to pull more of the belt
out of the retractor once the lock has been set.7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If your vehicle has the passenger sensing system
and the air bag is off, the off indicator will be lit and
stay lit in the inside rearview mirror when the key
is turned to RUN or START. Never put a rear-facing
child restraint in the right front passenger seat
unless the air bag is off.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint.
If after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.

If the on indicator is still lit, use the air bag off switch to
turn off the air bag or secure the child in the child
restraint in a rear seat position in the vehicle if one is
available and check with your dealer. SeeAir Bag
Off Switch on page 1-73for more on this, including
important safety information.
For heavy duty pickups without the passenger sensing
system, use the air bag off switch to turn the air bag off or
install the infant restraint in a rear seat position.
{CAUTION:
If the air bag ON indicator comes on when you
have a rear-facing child restraint installed in
the right front passenger’s seat, it means that
the passenger sensing system has not turned
off the passenger’s frontal air bag. A child in a
rear-facing child restraint can be seriously
injured or killed if the right front passenger’s
air bag inates. This is because the back of
the rear-facing child restraint would be very
close to the inating air bag. Don’t use a
rear-facing child restraint in the right front
passenger’s seat unless the air bag is off.To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.
If you had turned the air bag off with the switch,
remember to be sure to use the air bag off switch to
turn on the right front passenger’s air bag when
you remove the child restraint from the vehicle unless
the person who will be sitting there is a member of
a passenger air bag risk group. SeeAir Bag Off Switch
on page 1-73.{CAUTION:
If the right front passenger’s air bag is turned
off for a person who isn’t in a risk group
identied by the national government, that
person won’t have the extra protection of an
air bag. In a crash, the air bag wouldn’t be able
to inate and help protect the person sitting
there. Don’t turn off the passenger’s air bag
unless the person sitting there is in a risk
group. See″Air Bag Off Switch″in the Index
for more on this, including important safety
information.

Air Bag Systems
This part explains the air bag system.
Your vehicle has air bags – one air bag for the driver
and another air bag for the right front passenger.
Frontal air bags are designed to help reduce the risk of
injury from the force of an inating frontal air bag.
But these air bags must inate very quickly to do their
job and comply with federal regulations.
Here are the most important things to know about the
air bag systems:
{CAUTION:
You can be severely injured or killed in a crash
if you are not wearing your safety belt — even
if you have air bags. Wearing your safety belt
during a crash helps reduce your chance of
hitting things inside the vehicle or being
ejected from it. Air bags are designed to work
with safety belts, but do not replace them. Air
bags are designed to deploy only in moderate
to severe frontal and near frontal crashes.
CAUTION: (Continued)
CAUTION: (Continued)
They are not designed to inate in rollover,
rear or low-speed frontal crashes, or in many
side crashes. And, for some unrestrained
occupants, air bags may provide less
protection in frontal crashes than more
forceful air bags have provided in the past.
Everyone in your vehicle should wear a safety
belt properly — whether or not there is an air
bag for that person.
{CAUTION:
Air bags inate with great force, faster than the
blink of an eye. If you’re too close to an
inating air bag, as you would be if you were
leaning forward, it could seriously injure you.
Safety belts help keep you in position before
and during a crash. Always wear your safety
belt, even with air bags. The driver should sit
as far back as possible while still maintaining
control of the vehicle.
1-67

{CAUTION:
Anyone who is up against, or very close to,
any air bag when it inates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle’s safety belt system nor its air bag
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,
seeOlder Children on page 1-32andInfants
and Young Children on page 1-34.
There is an air bag
readiness light on the
instrument panel cluster,
which shows the air
bag symbol.The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAir Bag Readiness Light on page 3-36
for more information.
Where Are the Air Bags?
The driver’s air bag is in the middle of the
steering wheel.
1-68

The right front passenger’s air bag is in the instrument
panel on the passenger’s side.
{CAUTION:
If something is between an occupant and an
air bag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating air bag must be kept clear. Don’t put
anything between an occupant and an air bag,
and don’t attach or put anything on the
steering wheel hub or on or near any other air
bag covering.
1-69

When Should an Air Bag Inate?
An air bag is designed to inate in a moderate to severe
frontal, or near-frontal crash. The air bag will inate
only if the impact speed is above the system’s designed
“threshold level.”
In any particular crash, no one can say whether an air
bag should have inated simply because of the damage
to a vehicle or because of what the repair costs were.
Ination is determined by the angle of the impact
and how quickly the vehicle slows down in frontal or
near-frontal impacts.
The air bag system is designed to work properly under
a wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. SeeOff-Road
Driving on page 4-21for more tips on off-road driving.
Single Stage vs. Dual Stage Air Bags
Depending on the weight of your vehicle you will
have either “Single Stage Air Bags” or “Dual Stage Air
Bags”. Vehicles that have a passenger sensing
system also have dual stage air bags. If the rearview
mirror in your vehicle has a passenger air bag
status indicator printed on it, your vehicle has the
passenger sensing system and therefore, it has dualstage air bags. If the rearview mirror in your vehicle
does not have a passenger air bag status indicator
printed on it, then your vehicle does not have the
passenger sensing system and it has single stage air
bags. SeePassenger Air Bag Status Indicator on
page 3-40orPassenger Sensing System on page 1-78.
Dual Stage Air Bags
If your vehicle has frontal air bags with dual stage
deployment, the amount of restraint will adjust according
to crash severity. For moderate frontal impacts, these
air bags inate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.
If the front of your vehicle goes straight into a wall that
does not move or deform, the threshold level for the
reduced deployment is about 10 to 16 mph
(16 to 25 km/h), and the threshold level for a full
deployment is about 20 to 25 mph (32 to 40 km/h). The
threshold level can vary, however, with specic
vehicle design, so that it can be somewhat above or
below this range.
If your vehicle strikes something that will move or
deform, such as a parked car, the threshold level will be
higher. The air bag is not designed to inate in
rollovers, rear impacts, or in many side impacts because
ination would not help the occupant.
1-70

Seat Position Sensors
Vehicle’s with dual stage air bags are also equipped
with special sensors which enable the sensing system to
monitor the position of both the driver and passenger
front seats. The seat position sensor provides
information which is used to determine if the air bags
should deploy at a reduced level or at full deployment.
Single Stage Air Bags
If your vehicle has frontal air bags with single stage
deployment and your vehicle goes straight into a wall
that does not move or deform, the threshold level
is about 13 to 16 mph (20 to 25 km/h). The threshold
level can vary, however, with specic vehicle design, so
that it can be somewhat above or below this range.
If your vehicle strikes something that will move or
deform, such as a parked car, the threshold level will be
higher. The air bag is not designed to inate in
rollovers, rear impacts, or in many side impacts because
ination would not help the occupant.
What Makes an Air Bag Inate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. The
sensing system triggers a release of gas from the
inator, which inates the air bag. The inator, air bag,
and related hardware are all part of the air bag
modules inside the steering wheel and in the instrument
panel in front of the right front passenger.
How Does an Air Bag Restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. Air bags supplement the
protection provided by safety belts. Air bags distribute
the force of the impact more evenly over the occupant’s
upper body, stopping the occupant more gradually.
But air bags would not help you in many types of
collisions, including rollovers, rear impacts and many
side impacts, primarily because an occupant’s motion is
not toward those air bags. Air bags should never be
regarded as anything more than a supplement to safety
belts, and then only in moderate to severe frontal or
near-frontal collisions.
1-71

What Will You See After an
Air Bag Inates?
After an air bag inates, it quickly deates, so quickly
that some people may not even realize the air bag
inated. Some components of the air bag module – the
steering wheel hub for the driver’s air bag, or the
instrument panel for the right front passenger’s
bag – will be hot for a short time. The parts of the bag
that come into contact with you may be warm, but
not too hot to touch. There will be some smoke and dust
coming from the vents in the deated air bags. Air
bag ination does not prevent the driver from seeing or
being able to steer the vehicle, nor does it stop
people from leaving the vehicle.
{CAUTION:
When an air bag inates, there is 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
CAUTION: (Continued)
CAUTION: (Continued)
to do so. If you have breathing problems but
can not get out of the vehicle after an air bag
inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an air bag deployment, you
should seek medical attention.
In many crashes severe enough to inate the air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
Air bags are designed to inate only once. After
they inate, you will need some new parts for
your air bag system. If you do not get them, the air
bag system will not be there to help protect you
in another crash. A new system will include air bag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
1-72

Your vehicle is equipped with electronic frontal
sensors which help the sensing system distinguish
between a moderate and a more severe frontal
impact. Your vehicle is also equipped with a crash
sensing and diagnostic module, which records
information about the frontal air bag system. The
module records information about the readiness of
the system and when the system commands air
bag ination. It records the status of the driver’s
safety belt usage in a crash in which the air
bag deploys or a crash in which the air bag nearly
deploys. The module also records speed, engine
rpm, brake and throttle data.
Let only qualied technicians work on your air bag
systems. Improper service can mean that an air
bag system will not work properly. See your dealer
for service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, the bag
may not work properly. You may have to replace the
air bag module in the steering wheel or both the
air bag module and the instrument panel for
the right front passenger’s air bag. Do not open or
break the air bag coverings.
Air Bag Off Switch
Regular Cab and Extended Cab Models
If your vehicle is a regular cab model or an extended
cab model, it has a switch on the instrument panel
that you can use to turn off the right front passenger’s
air bag.
