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.
Air Bag System
This part explains the air bag system.
Your vehicle has ªNext Generationº frontal
air bags
-- one air bag for the driver and another
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
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 system:
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. Air bags 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 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's an air bag for that person.

CAUTION:
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 before and during a crash. Always
wear your safety belt, even with Next Generation air
bags. The driver should sit as far back as possible
while still maintaining control of the vehicle.
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.
CAUTION: (Continued)
CAUTION: (Continued)
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 the air
bag symbol.
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.

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.
When should an air bag inflate?
An air bag is designed to inflate in a moderate to severe
frontal or near
-frontal crash. The air bag will 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 14 to 18 mph (23 to 29 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, suchas a parked car, the threshold level will be higher. The
air bag is not designed to inflate in rollovers, side
impacts or rear impacts, because inflation would not
help the occupant.
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.
Inflation 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. See ªOff
-Road
Drivingº in the Index for more tips on off
-road driving.
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. 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 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 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.
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, 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 vents in the deflated
air bags. Air bag inflation doesn't prevent the driver from
seeing or from 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 door.

Air bags are designed to inflate only once. After they
inflate, you'll need some new parts for your air bag
system. If you don't get them, the air bag system
won't 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.

Your vehicle is equipped with a diagnostic module,
which records information about the air bag system.
The module records information about the readiness
of the system, when the sensors are activated and
driver's safety belt usage at deployment.

1-30 Adding Equipment to Your Air
Bag-Equipped Vehicle
Q:If I add a push bumper or a bicycle rack to the
front of my vehicle, will it keep the air bags
from working properly?
A:As long as the push bumper or bicycle rack is
attached to your vehicle so that the vehicle's basic
structure isn't changed, it's not likely to keep the
air bags from working properly in a crash.
Q:Is there anything I might add to the front of the
vehicle that could keep the air bags from
working properly?
A:Yes. If you add things that change your vehicle's
frame, bumper system, front end sheet metal or
height, they may keep the air bag system from
working properly. Also, the air bag system may not
work properly if you relocate any of the air bag
sensors. If you have any questions about this, you
should contact Customer Assistance before you
modify your vehicle. (The phone numbers and
addresses for Customer Assistance are in Step Two of
the Customer Satisfaction Procedure in this manual.
See ªCustomer Satisfaction Procedureº in the Index.)
Center Front Passenger Position
(4
-Door Models)
Lap Belt
If your vehicle has a front bench seat, someone can sit in
the center 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.To make the belt shorter, pull its free end as shown until
the belt is snug.
Buckle, position and release it the same way as the lap
part of a lap
-shoulder belt. If the belt isn't long enough,
see ªSafety Belt Extenderº at the end of this section.
Make sure the release button on the buckle is positioned
so you would be able to unbuckle the safety belt quickly
if you ever had to.

Rear Seat Passengers
It's very important for rear seat passengers to buckle up!
Accident statistics show that unbelted people in the rear
seat are hurt more often in crashes than those who are
wearing safety belts.
Rear passengers who aren't safety belted can be thrown
out of the vehicle in a crash. And they can strike others
in the vehicle who are wearing safety belts.
Rear Seat Outside Passenger Positions
Lap-Shoulder Belt
The positions next to the windows have lap
-shoulder
belts. Here's how to wear one properly.
1. Pick up the latch plate and pull the belt across you.
Don't let it get twisted. The 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.
2. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.

When the shoulder belt is pulled out all the way, it
will lock. If it does, let it go back all the way and
start again.
If the belt is not long enough, see ªSafety Belt
Extenderº at the end of this section.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
3. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder part.
