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 an
accident — even one that is not your fault — you
and your passengers 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 part 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 babies. If a child will be
riding in your vehicle, seeOlder Children on page 1-26
orInfants and Young Children on page 1-28. Follow
those rules for everyone’s protection.
First, you will want to know which restraint systems your
vehicle has.
We will start with the driver position.
Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.
1-13
Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, seeDriver Position on page 1-13.
The right front passenger’s safety belt works the same
way as the driver’s safety belt — except for one
thing. If you ever pull the shoulder portion of the belt out
all the way, you will engage the child restraint locking
feature. If this happens, just let the belt go back all
the way and start again.
Rear Seat Passengers
It is very important for rear seat passengers to buckle
up! Accident statistics show that unbelted people in
the rear seat are hurt more often in crashes than those
who are wearing safety belts.
Rear passengers who are not safety belted can be
thrown out of the vehicle in a crash. And they can strike
others in the vehicle who are wearing safety belts.
Lap-Shoulder Belt
All rear seat positions have lap-shoulder belts. Here is
how to wear one properly.
1. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The 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.
1-21
Safety Belt Extender
If the vehicle’s safety belt will fasten around you, you
should use it.
But if a safety belt is not long enough, your dealer will
order you an extender. It is free. 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, just 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.
1-26
Q:What is the proper way to wear safety belts?
A:If possible, 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. It should never be worn over
the abdomen, which could cause severe or even
fatal internal injuries in a crash.
Accident statistics show that children are safer if they
are restrained in the rear seat.
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.
{CAUTION:
Never do this.
Here two children are wearing the same belt.
The belt can not properly spread the impact
forces. In a crash, the two children can be
crushed together and seriously injured. A belt
must be used by only one person at a time.
1-27
Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt
is very close to the child’s face or neck?
A:If the child is sitting in a seat next to a window,
move the child toward the center of the vehicle.
If the child is sitting in the center rear seat
passenger position, move the child toward the
safety belt buckle. In either case, be sure that the
shoulder belt still is on the child’s shoulder, so
that in a crash the child’s upper body would have
the restraint that belts provide.
{CAUTION:
Never do this.
Here a child is sitting in a seat that has a
lap-shoulder belt, but the shoulder part is
behind the child. If the child wears the belt in
this way, in a crash the child might slide under
the belt. The belt’s force would then be applied
right on the child’s abdomen. That could cause
serious or fatal injuries.
The lap portion of the belt should be worn low and snug
on the hips, just touching the child’s thighs. This
applies belt force to the child’s pelvic bones in a crash.
Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone to use safety restraints.
1-28
In fact, the law in every state in the United States and
in every Canadian province says children up to
some age must be restrained while in a vehicle.
Every time infants and young children ride in vehicles,
they should have the protection provided by appropriate
restraints. Young children should not use the vehicle’s
adult safety belts alone, unless there is no other choice.
Instead, they need to use a child restraint.
{CAUTION:
People should never hold a baby in their arms
while riding in a vehicle. A baby does not
weigh much — until a crash. During a crash a
baby will become so heavy it is not possible
to hold it. For example, in a crash at only
25 mph (40 km/h), a 12 lb (5.5 kg) baby will
suddenly become a 240 lb (110 kg) force on a
person’s arms. A baby should be secured in
an appropriate restraint.
