Questions and Answers About
Safety Belts
Q:
Will I be trapped in the vehicle
after a crash if I am wearing a
safety belt?
A:Youcouldbe — whether you are
wearing a safety belt or not. But
your chance of being conscious
during and after an accident, so
youcanunbuckle and get out, is
muchgreater if you are belted.
And you can unbuckle a safety
belt, even if you are upside down.
Q:If my vehicle has airbags,
why should I have to wear
safety belts?
A:Airbags are supplemental
systems only; so they workwith
safety belts — not instead of
them. Whether or not an airbag is
provided, all occupants still have
to buckle up to get the most
protection. That is true not only in
frontal collisions, but especially
in side and other collisions.
Q:If I am a good driver, and I
never drive far from home, why
should I wear safety belts?
A:You may be an excellent driver,
but if you are in a crash — even
one that is not your fault — you
and your passenger(s) can be
hurt. Being a good driver does not
protect you from things beyond
your control, such as bad drivers.
Most accidents occur within
25 miles (40 km) of home. And
the greatest number of serious
injuries and deaths occur at
speeds of less than 40 mph
(65 km/h).
Safety belts are for everyone.
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 1-25orInfants and Young
Children on page 1-28. 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.
1-14 Seats and Restraint System
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
If you are using a rear seating
position with a detachable safety
belt and the safety belt is not
attached, see60/40 Split Bench
Seat (H3) on page 1-7or60/40 Split
Bench Seat (H3T) on page 1-9for
instruction on reconnecting the
safety belt to the mini-buckle.
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 right front
seating position may affect
the passenger sensing system.
SeePassenger Sensing
System on page 1-54for
more information.
1-20 Seats and Restraint System
Rear Safety Belt Comfort
Guides
Rear shoulder belt comfort guides
may provide added safety 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.There is one guide for each
outboard passenger position in the
rear seat. Here is how to install
a comfort guide to the safety belt:
1. Pull the elastic cord out from
between the edge of the
seatback and the interior body to
remove the guide from its
storage clip.2. Place the guide over the belt and
insert the two edges of the belt
into the slots of the guide.

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 do not wear
safety belts.
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 is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
Safety Belt Extender
If the safety belt will fasten around
you, you should use it.
But if a safety belt is not long
enough, your dealer/retailer 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 t. The extender
has been designed for adults.
Never use it for securing child seats.
To wear it, attach it to the regular
safety belt. For more information, see
the instruction sheet that comes with
the extender.
Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the
vehicle’s safety belts.
Seats and Restraint System 1-25
The manufacturer’s instructions that
come with the booster seat, state the
weight and height limitations for that
booster. Use a booster seat with a
lap-shoulder belt until the child
passes the below t test:
Sit all the way back on the seat.
Do the knees bend at the seat
edge? If yes, continue. If no,
return to the booster seat.
Buckle the lap-shoulder belt.
Does the shoulder belt rest on the
shoulder? If yes, continue. If no,
try using the rear safety belt
comfort guide. See “Rear Safety
Belt Comfort Guides” under
Lap-Shoulder Belt on page 1-20
for more information. If the
shoulder belt still does not rest on
the shoulder, then return to the
booster seat.
Does the lap belt t low and snug
on the hips, touching the thighs?
If yes, continue. If no, return to the
booster seat.
Can proper safety belt t be
maintained for the length of the
trip? If yes, continue. If no, return
to the booster seat.
Q:What is the proper way to
wear safety belts?
A:An older child should wear a
lap-shoulder belt and get the
additional restraint a shoulder belt
can provide. The shoulder belt
should not cross the face or neck.
The lap belt should t snugly
below the hips, just touching the
top of the thighs. This applies belt
force to the child’s pelvic bones in
a crash. It should never be worn
over the abdomen, which could
cause severe or even fatal
internal injuries in a crash.Also see “Rear Safety Belt Comfort
Guides” underLap-Shoulder Belt
on page 1-20.
According to accident statistics,
children and infants are safer when
properly restrained in a child
restraint system or infant restraint
system secured in a rear seating
position.
In a crash, children who are not
buckled up can strike other people
who are buckled up, or can be
thrown out of the vehicle. Older
children need to use safety belts
properly.
