Safety Belts
This section of the manual
describes how to use safety belts
properly. It also describes some
things not to do with safety belts.
{WARNING
Do not let anyone ride where
a safety belt cannot be worn
properly. In a crash, if you or your
passenger(s) are not wearing
safety belts, the injuries can be
much worse. You can hit things
inside the vehicle harder or be
ejected from the vehicle. You
and your passenger(s) can be
seriously injured or killed. In the
same crash, you might not be,
if you are buckled up. Always
fasten your safety belt, and
check that your passenger(s)
are restrained properly too.
{WARNING
It is extremely dangerous to ride
in a cargo area, inside or outside
of a vehicle. In a collision, people
riding in these areas are more
likely to be seriously injured or
killed. Do not allow people to ride
in any area of your vehicle that
is not equipped with seats and
safety belts. Be sure everyone in
the vehicle is in a seat and using
a safety belt properly.
This vehicle has indicators as a
reminder to buckle the safety belts.
See Safety Belt Reminders on
page 5‑17 for additional information. In most states and in all Canadian
provinces, the law requires wearing
safety belts. Here is why:
You never know if you will be in
a crash. If you do have a crash,
you do not know if it will be a
serious one.
A few crashes are mild, and some
crashes can be so serious that even
buckled up, a person would not
survive. But most crashes are in
between. In many of them, people
who buckle up can survive and
sometimes walk away. Without
safety belts they could have been
badly hurt or killed.
After more than 40 years of safety
belts in vehicles, the facts are clear.
In most crashes buckling up does
matter ... a lot!

crash, you would move forward
too much, which could increase
injury. The shoulder belt should fit
snugly against your body. Q: What is wrong with this?

{WARNING
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 are not as
strong as shoulder bones. You
could also severely injure internal
organs like your liver or spleen.
The shoulder belt should go over
the shoulder and across the
chest.Q: What is wrong with this?
A:
The belt is behind the body.
{WARNING
You can be seriously injured by
not wearing the lap-shoulder belt
properly. In a crash, you would
not be restrained by the shoulder
belt. Your body could move too
far forward increasing the chance
of head and neck injury. You
might also slide under the lap
belt. The belt force would then
be applied right on the abdomen.
That could cause serious or fatal
injuries. The shoulder belt should
go over the shoulder and across
the chest.

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 except for
the center front passenger position,
if equipped, which has a lap belt.
See Lap Belt on page 3‑36 for more
information.
The lap‐shoulder belts for the first
and second row seating positions
are equipped with free‐falling latch
plates. If the vehicle has a third row,
the lap‐shoulder belts have either
free‐falling or cinching latch plates.

Replacing Safety Belt
System Parts After a
Crash
{WARNING
A crash can damage the safety
belt system in the vehicle.
A damaged safety belt system
may not properly protect the
person using it, resulting in
serious injury or even death in
a crash. To help make sure the
safety belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.After a minor crash, replacement of
safety belts may not be necessary.
But the safety belt assemblies that
were used during any crash may
have been stressed or damaged.
See your dealer to have the safety
belt assemblies inspected or
replaced.
New parts and repairs may be
necessary even if the safety belt
system was not being used at the
time of the crash.
Have the safety belt pretensioners
checked if the vehicle has been in a
crash, or if the airbag readiness light
stays on after you start the vehicle
or while you are driving. See
Airbag
Readiness Light on page 5‑18.
