2. The seat belt latch plate is above the back of
your seat. Grasp the latch plate and pull out the
belt. Slide the latch plate up the webbing as far as
necessary to make the belt go around your lap.
3. When the belt is long enough to fit, insert the
latch plate into the buckle until you hear a "click."

WARNING!
A belt that is buckled into the wrong buckle will
not protect you properly. The lap portion could
ride too high on your body, possibly causing
internal injuries. Always buckle your belt into the
buckle nearest you.
A belt that is too loose will not protect you as
well. In a sudden stop you could move too far
forward, increasing the possibility of injury. Wear
your seat belt snugly.
A belt that is worn under your arm is very
dangerous. Your body could strike the inside
surfaces of the vehicle in a collision, increasing
head and neck injury. A belt worn under the arm
can cause internal injuries. Ribs aren't as strong
as shoulder bones. Wear the belt over your
shoulder so that your strongest bones will take
the force in a collision.
A shoulder belt placed behind will not protect
you from injury during a collision. You are more
likely to hit your head in a collision if you do not
wear your shoulder belt. The lap and shoulder
belt are meant to be used together.
4. Position the lap belt across your thighs, below
your abdomen. To remove slack in the lap portion,
pull up a bit on the shoulder belt. To loosen the lap
belt if it is too tight, tilt the latch plate and pull on
the lap belt. A snug belt reduces the risk of sliding
under the belt in a collision.
WARNING!
A lap belt worn too high can increase the risk of
injury in a collision. The belt forces won't be at
the strong hip and pelvic bones, but across your
abdomen. Always wear the lap part of your seat
belt as low as possible and keep it snug.
A twisted belt can't do its job as well. In a
collision it could even cut into you. Be sure the
belt is straight. If you can't straighten a belt in
your vehicle, take it to your authorized dealer
and have it fixed.
5. Position the shoulder belt on your chest so that
it is comfortable and not resting on your neck. The
retractor will withdraw any slack in the belt.
