Reclining Seatbacks
{WARNING
Sitting in a reclined position when
the vehicle is in motion can be
dangerous. Even when buckled
up, the safety belts cannot do
their job when reclined like this.(Continued)
WARNING (Continued)
The shoulder belt cannot do its
job because it will not be against
your body. Instead, it will be in
front of you. In a crash, you could
go into it, receiving neck or other
injuries.
The lap belt cannot do its job
either. In a crash, the belt could
go up over your abdomen.
The belt forces would be there,
not at your pelvic bones. This
could cause serious internal
injuries.
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear the
safety belt properly.
Manual Reclining Seatbacks
{WARNING
You can lose control of the
vehicle if you try to adjust a
manual driver seat while the
vehicle is moving. The sudden
movement could startle and
confuse you, or make you push
a pedal when you do not want to.
Adjust the driver seat only when
the vehicle is not moving.
{WARNING
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.

Repeat Steps 1 through 3 for the
other seatback, if desired.
Raising the Seatback
{WARNING
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.
{WARNING
A safety belt that is improperly
routed, not properly attached,
or twisted will not provide the
protection needed in a crash.
The person wearing the belt could
be seriously injured. After raising
the rear seatback, always check
to be sure that the safety belts
are properly routed and attached,
and are not twisted. To raise a seatback:
1. Lift the seatback up and push
it rearward to lock it in place.
Make sure the safety belt is
in the retainer clip and is
not twisted or caught in the
seatback.
A tab near the seatback lever
retracts when the seatback is
locked in place.
2. Push and pull the top of the seatback to be sure it is locked
into position.
3. Repeat Steps 1 and 2 for the other seatback, if necessary.
When the seat is not in use, it
should be kept in the upright,
locked position.

How to Wear Safety Belts
Properly
This section is only for people of
adult size.
Be aware that there are special
things to know about safety belts
and children. And there are different
rules for smaller children and
infants. If a child will be riding in
the vehicle, seeOlder Children on
page 3‑44 orInfants and Young
Children on page 3‑46. Follow those
rules for everyone's protection.
It is very important for all occupants
to buckle up. Statistics show that
unbelted people are hurt more often
in crashes than those who are
wearing safety belts.
Occupants who are not buckled up
can be thrown out of the vehicle in a
crash. And they can strike others in
the vehicle who are wearing safety
belts. First, before you or your
passenger(s) wear a safety belt,
there is important information
you should know.
Sit up straight and always keep
your feet on the floor in front of you.
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 would be
less likely to slide under the lap
belt. If you slid under it, the belt
would apply force on 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 shoulder belt locks if there is a
sudden stop or crash.

Q: What is wrong with this?
A:The belt is twisted across
the body.
{WARNING
You can be seriously injured by a
twisted belt. In a crash, you would
not 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.
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is
adjustable, so you can sit up
straight. To see how, see “Seats”
in the Index.2. Pick up the latch plate and pull the belt across you. Do not let it
get twisted.
The lap-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.

Seats and Restraints 3-23
If the shoulder portion of a
passenger belt is pulled out
all the way, the child restraint
locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.
3. Push the latch plate into thebuckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Safety
Belt Extender on page 3‑27. Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
If equipped with a shoulder
belt height adjuster, move it
to the height that is right for
you. See
“Shoulder Belt Height
Adjustment” later in this section
for instructions on use and
important safety information.
4. To make the lap part tight, pull up on the shoulder belt.
It may be necessary to pull
stitching on the safety belt
through the latch plate to fully
tighten the lap belt on smaller
occupants.
To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position. Slide
the latch plate up the safety belt
webbing, when the safety belt is not
in use. The latch plate should rest
on the stitching on the safety belt,
near the guide loop on the side wall.
Before a door is closed, be sure
the safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
safety belt and the vehicle.

Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
right front passenger seating
positions.
Adjust the height so the
shoulder portion of the belt is
on the shoulder and not falling
off of it. The belt should be close
to, but not contacting, the neck.
Improper shoulder belt height
adjustment could reduce the
effectiveness of the safety belt in
a crash. SeeHow to Wear Safety
Belts Properly on page 3‑17.
Press the release button (A) and
move the height adjuster to the
desired position. The adjuster
can be moved up by pushing the
slide/trim up. After the adjuster is
set to the desired position, try to
move it down without pushing the
release button to make sure it has
locked into position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for front outboard
occupants. Although the safety
belt pretensioners cannot be seen,
they are part of the safety belt
assembly. They can help tighten
the safety belts during the early
stages of a moderate to severe
frontal and near frontal crash if
the threshold conditions for
pretensioner activation are met.
Pretensioners work only once. If the
pretensioners activate in a crash,
the pretensioners and probably
other parts of the vehicle's safety
belt system will need to be replaced.
See Replacing Safety Belt System
Parts After a Crash on page 3‑28.

If the vehicle has second row
seat‐mounted side impact airbags,
they are in the sides of the rear
seatback closest to the door.
{WARNING
If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into (Continued)
WARNING (Continued)
that person causing severe
injury or even death. The path
of an inflating airbag must be
kept clear. Do not put anything
between an occupant and an
airbag, and do not attach or put
anything on the steering wheel
hub or on or near any other
airbag covering.
Do not use seat accessories
that block the inflation path of a
seat-mounted side impact airbag.
Never secure anything to the roof
of a vehicle with roof-rail airbags
by routing a rope or tie down
through any door or window
opening. If you do, the path
of an inflating roof-rail airbag
will be blocked.
When Should an Airbag
Inflate?
Frontal airbags are designed
to inflate in moderate to severe
frontal or near frontal crashes to
help reduce the potential for severe
injuries mainly to the driver's or right
front passenger's head and chest.
However, they are only designed
to inflate if the impact exceeds
a predetermined deployment
threshold. Deployment thresholds
are used to predict how severe a
crash is likely to be in time for the
airbags to inflate and help restrain
the occupants.
Whether the frontal airbags will
or should deploy is not based on
how fast your vehicle is traveling.
It depends largely on what you hit,
the direction of the impact, and how
quickly your vehicle slows down.
