3. Pick up the latch plate and pull the belt across you.
Don't let it get twisted.
4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
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.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'd be less likely
to slide under the lap belt. If you slid under it, the belt
would apply force at 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 safety belt locks if there's a sudden stop or a crash.

Shoulder Belt Height Adjuster
Before you begin to drive, move the shoulder belt
adjuster to the height that is right for you.To move it down, push in at the word PRESS and move
the height adjuster to the desired position. You can move
the adjuster up just by pushing up on the shoulder belt
guide. After you move the adjuster to where you want it,
try to move it down without pushing in to make sure it
has locked into position.
Adjust the height so that the shoulder portion of the belt
is centered on your shoulder. The belt should be away
from your face and neck, but not falling off
your shoulder.

Q:What's wrong with this?
A:The shoulder belt is too loose. It won't give nearly
as much protection this way.
CAUTION:
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 against your body.

Q:What's wrong with this?
A:The belt is buckled in the wrong place.
CAUTION:
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 at the pelvic
bones. This could cause serious internal injuries.
Always buckle your belt into the buckle
nearest you.

Q:What's wrong with this?
A:The belt is over an armrest.
CAUTION:
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 at the
abdomen, not at the pelvic bones, and that could
cause serious or fatal injuries. Be sure the belt
goes under the armrests.

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 lap 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, 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. 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.
