Q:What's wrong with this?
A:The shoulder belt is worn under the arm. It should
be worn over the shoulder at all times.
CAUTION:
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 aren't as strong as shoulder bones.
You could also severely injure internal organs
like your liver or spleen.

Q:What's wrong with this?
A:The belt is twisted across the body.
CAUTION:
You can be seriously injured by a twisted belt. In
a crash, you wouldn't 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.

To unlatch the belt, just push the button on the buckle.
The belt should go back out of the way.
Before you close the door, be sure the belt is out of the
way. If you slam the door on it, you can damage both the
belt and your vehicle.
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 don't 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's more
likely that the fetus won't be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger's safety
belt properly, see ªDriver Positionº earlier in
this section.
The right front passenger's safety belt works the same
way as the driver's safety belt
-- except for one thing.
If you ever pull the shoulder portion of the belt out all
the way, you will engage the child restraint locking
feature. If this happens, just let the belt go back all the
way and start again.
Supplemental Restraint Systems (SRS)
This part explains the frontal and side impact
Supplemental Restraint Systems (SRS) or
air bag systems.
Your vehicle has four air bags
-- a ªNext Generationº
frontal air bag for the driver, another ªNext Generationº
frontal air bag for the right front passenger, a side
impact air bag for the driver, and another side impact air
bag for the right front passenger.Next Generation frontal air bags are designed to help
reduce the risk of injury from the force of an inflating
frontal air bag. But even these air bags must inflate very
quickly if they are 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 aren't 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 ªsupplemental restraintsº to the safety
belts. All air bags
-- even Next Generation air
bags
-- are designed to work with safety belts but
don't replace them.
CAUTION: (Continued)

1-39
CAUTION: (Continued)
Next Generation frontal air bags for the driver
and right front passenger are designed to work
only in moderate to severe crashes where the
front of your vehicle hits something. They aren't
designed to inflate at all in rollover, rear, side or
low
-speed frontal crashes. And, for unrestrained
occupants, Next Generation frontal air bags may
provide less protection in frontal crashes than
more forceful air bags have provided in the past.
The side impact air bags for the driver and right
front passenger are designed to inflate only in
moderate to severe crashes where something hits
the side of your vehicle. They aren't designed to
inflate in frontal, in rollover or in rear crashes.
Everyone in your vehicle should wear a safety
belt properly
-- whether or not there's an air bag
for that person.
CAUTION:
Both frontal and side impact air bags inflate with
great force, faster than the blink of an eye. If
you're too close to an inflating air bag, as you
would be if you were leaning forward, it could
seriously injure you. This is true even with Next
Generation frontal air bags. Safety belts help
keep you in position for air bag inflation before
and during a crash. Always wear your safety belt,
even with Next Generation frontal air bags. The
driver should sit as far back as possible while still
maintaining control of the vehicle. Front
occupants should not lean on or sleep against
the door.

CAUTION:
Children who are up against, or very close to, any
air bag when it inflates can be seriously injured
or killed. This is true even though your vehicle
has Next Generation frontal air bags. 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, see the part of this manual called
ªChildrenº and see the caution labels on the
sunvisors and the right front passenger's
safety belt.
There is an air bag readiness
light on the instrument
panel, which shows a
deployed air bag.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See ªAir Bag Readiness Lightº in the Index
for more information.

1-41 How the Air Bag Systems Work
Where are the air bags?
The driver's frontal air bag is in the middle of the
steering wheel.
The right front passenger's frontal air bag is in the
instrument panel on the passenger's side.

yellowblue
1-42
The driver's side impact air bag is in the side of the
driver's seatback closest to the door.
The right front passenger's side impact air bag is in the
side of the passenger's seatback closest to the door.
CAUTION:
If something is between an occupant and an air
bag, the bag might not inflate properly or it
might force the object into that person. The path
of an inflating 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 and don't let seat covers block the
inflation path of a side impact air bag.

1-43
When should an air bag inflate?
The driver's and right front passenger's frontal air bags
are designed to inflate in moderate to severe frontal or
near
-frontal crashes. The frontal air bags are designed to
inflate only if the impact speed is above the system's
designed ªthreshold level.º If your vehicle goes straight
into a wall that doesn't move or deform, the threshold
level is about 9 to 15 mph (14 to 24 km/h). The
threshold level can vary, however, with specific 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 driver's and right front passenger's
frontal air bags are not designed to inflate in rollovers,
side impacts, or rear impacts, because inflation would
not help the occupant.
The driver's and right front passenger's side impact air
bags are designed to inflate in moderate to severe side
crashes involving a front door. A side impact air bag
will inflate if the crash severity is above the system's
designed ªthreshold level.º The threshold level can vary
with specific vehicle design. Side impact air bags are not
designed to inflate in frontal or near
-frontal impacts,
rollovers or rear impacts, because inflation would not
help the occupant. A side impact air bag will only
deploy on the side of the vehicle that is struck.In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were. For
frontal air bags, inflation is determined by the angle of
the impact and how quickly the vehicle slows down in
frontal and near
-frontal impacts. For side impact air
bags, inflation is determined by the location of the
impact and how quickly the side of the vehicle deforms.
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. For both
frontal and side impact air bags, the sensing system
triggers a release of gas from the inflator, which inflates
the air bag. The inflator, air bag and related hardware
are all part of the air bag modules inside the steering
wheel, instrument panel and the side of the front
seatbacks closest to the door.

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. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The air bag supplements 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 the frontal air
bags would not help you in many types of collisions,
including rollovers, rear impacts, and side impacts,
primarily because an occupant's motion is not toward
the air bag. Side impact air bags would not help you in
many types of collisions, including frontal or near
frontal collisions, rollovers, and rear 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 for
the driver's and right front passenger's frontal air bags,
and only in moderate to severe side collisions for the
driver's and right front passenger's side impact air bags.What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates, so quickly
that some people may not even realize the air bag
inflated. Some components of the air bag module
-- the
steering wheel hub for the driver's air bag, the
instrument panel for the right front passenger's bag, the
side of the seatback closest to the door for the driver and
right front passenger's side impact air bags
-- 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 deflated air bags. Air bag inflation doesn't
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 inflates, 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 to do so.
If you have breathing problems but can't get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window or a door.
