72 Seats and Restraints
When riding in a vehicle, you travel
as fast as the vehicle does. If the
vehicle stops suddenly, you keep
going until something stops you.
It could be the windshield, the
instrument panel, or the seat belts!
When you wear a seat belt, you and
the vehicle slow down together.
There is more time to stop because
you stop over a longer distance and,
when worn properly, your strongest
bones take the forces from the seat
belts. That is why wearing seat belts
makes such good sense.
Questions and Answers About
Seat Belts
Q: Will I be trapped in the vehicleafter a crash if I am wearing a
seat belt?
A: You could be—whether you are
wearing a seat belt or not. Your
chance of being conscious
during and after a crash, so you
can unbuckle and get out, is
much greater if you are belted. Q: If my vehicle has airbags, why
should I have to wear seat
belts?
A: Airbags are supplemental
systems only. They work with
seat belts —not instead of them.
Whether or not an airbag is
provided, all occupants still have
to buckle up to get the most
protection.
Also, in nearly all states and in
all Canadian provinces, the law
requires wearing seat belts.
How to Wear Seat Belts
Properly
This section is only for people of
adult size.
There are special things to know
about seat belts and children, and
there are different rules for smaller
children and infants. If a child will be
riding in the vehicle, see Older
Children 091 orInfants and Young
Children 093. 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 seat belts.
There are important things to know
about wearing a seat belt properly.
.
Sit up straight and always keep
your feet on the floor in front
of you.
. Always use the correct buckle
for your seating position.
. Wear the lap part of the belt low
and snug on the hips, just
touching the thighs. In a crash,

Mexico-11349114) - 2018 - crc - 9/21/17
Seats and Restraints 73
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.
. Wear the shoulder belt 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.
{Warning
You can be seriously injured,
or even killed, by not wearing
your seat belt properly.
. Never allow the lap or
shoulder belt to become
loose or twisted.
. Never wear the shoulder
belt under both arms or
behind your back.
. Never route the lap or
shoulder belt over an
armrest.
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.
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.
Engaging the child restraint
locking feature in the front
outboard seating position may
affect the passenger sensing
system. See
Passenger
Sensing System 085.

Seat Belt Pretensioners
This vehicle has seat belt
pretensioners for front outboard
occupants. Although the seat belt
pretensioners cannot be seen, they
are part of the seat belt assembly.
They can help tighten the seat belts
during the early stages of a
moderate to severe frontal, near
frontal, or rear crash if the threshold
conditions for pretensioner
activation are met. Seat belt
pretensioners can also help tighten
the seat belts in a side crash or a
rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash,
the pretensioners and probably
other parts of the vehicle’s seat belt
system will need to be replaced.
SeeReplacing Seat Belt System
Parts after a Crash 078.
Do not sit on the outboard seat belt
while entering or exiting the vehicle
or at any time while sitting in the
seat. Sitting on the seat belt can
damage the webbing and hardware.
Rear Seat Belt Comfort Guides
{Warning
A seat belt that is not properly
worn may not provide the
protection needed in a crash. The
person wearing the belt could be
seriously injured. 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.
Rear seat belt comfort guides may
provide added seat belt comfort for
older children who have outgrown
booster seats and for some adults.
When installed on a shoulder belt,
the comfort guide positions the
shoulder belt away from the neck
and head.
Second Row Outboard Seating
Positions
The vehicle may be equipped with
comfort guides in a pocket on the
side of each second row outboard seating position. Use the following
instructions to install the comfort
guides.
If not equipped on the seat, comfort
guides for the second row outboard
seating positions may be provided
in a package in the glovebox or
cargo area, or they are available
through your dealer. Instructions are
included with the guide.
To install a pocket-style guide:
1. Remove the guide from its
storage pocket on the side of
the seat.

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 seat
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making seat
belts effective is wearing them
properly.
Seat Belt Extender
If the vehicle's seat belt will fasten
around you, you should use it.
But if a seat belt is not long enough,
your dealer will order you an
extender. When you go in to order it,
take the heaviest coat you will wear,
so the extender will be long enough
for you. To help avoid personal
injury, do not let someone else use
it, and use it only for the seat it is
made to fit. The extender has been
designed for adults. Never use it for
securing child restraints. For more
information on the proper use and fit
of seat belt extenders see the
instruction sheet that comes with
the extender.
Safety System Check
Periodically check the seat belt
reminder, seat belts, buckles, latch
plates, retractors, shoulder belt
height adjusters (if equipped), and
seat belt anchorages to make sure
they are all in working order. Look
for any other loose or damaged seat
belt system parts that might keep aseat belt system from performing
properly. See your dealer to have it
repaired. Torn or frayed seat belts
may not protect you in a crash.
They can rip apart under impact
forces. If a belt is torn or frayed,
have it replaced immediately.
Make sure the seat belt reminder
light is working. See
Seat Belt
Reminders 0134.
Keep seat belts clean and dry. See
Seat Belt Care 077.
Seat Belt Care
Keep belts clean and dry.
{Warning
Do not bleach or dye seat belt
webbing. It may severely weaken
the webbing. In a crash, they
might not be able to provide
adequate protection. Clean and
rinse seat belt webbing only with
mild soap and lukewarm water.
Allow the webbing to dry.
