3. 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.
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 Safety
Belt Extender

positioned
so you would be able to unbuckle the
safety belt quickly
if you ever had to.
5. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt.

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 crash,
or if you
pull the belt very quickly out of the retractor.

Q: What’s wrong with this?
A: The shoulder belt is too loose. It won’t give nearly
as much protection this way.
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?
You can be seriously
in- -ed 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.
A: The shoulder belt is worn under the arm. It should
be worn over the shoulder at all times.

Q: What’s wrong with this?
A: The belt is twisted across the body. 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.

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.
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.
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
Driver Position on page 1-13.
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
which may turn
off the passenger’s frontal air bag. If this
happens unintentionally, just let the belt go back all
the way and start again.
Center Passenger Position

Lap Belt
When you sit in a center 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
Safety Belt Extender on page 1-29.
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.
