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.

1-35
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.

1-36
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 Systems
This part explains the frontal and side impact air
bag systems.
Your vehicle has four air bags
-- a frontal air bag for
the driver, another 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.
Frontal air bags are designed to help reduce the risk of
injury from the force of an inflating frontal air bag. But
these air bags must inflate very quickly to do their job
and comply with federal regulations.

1-37
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 designed to work with safety belts but
don't replace them.
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 or low
-speed frontal crashes,
or in many side crashes. And, for some
unrestrained occupants, frontal air bags may
provide less protection in frontal crashes than
more forceful air bags have provided in the past.
CAUTION: (Continued)
CAUTION: (Continued)
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. Safety belts help keep you in
position for air bag inflation before and during a
crash. Always wear your safety belt, even with
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.

1-38
CAUTION:
Anyone who is up against, or very close to, any
air bag when it inflates 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, see the part of this manual
called ªChildren.º
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.

1-39 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.
The driver's side impact air bag is in the side of the
driver's seatback closest to the door.

1-40
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 causing
severe injury or even death. 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. Don't let seat covers block the inflation
path of a side impact air bag.

1-41
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. But they 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
16 mph (14 to 26 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, rear
impacts, or in many side impacts because inflation
would not help the occupant.
The side impact air bags are designed to inflate in
moderate to severe side crashes. 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 and severity
of the impact.
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. 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.
