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 1-31
orInfants and Young Children on page 1-34. 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.3. 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.
4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 1-30.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
1-18
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.
Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, seeDriver Position on page 1-18.
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.
1-24
Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the driver
and right front passenger. Although you cannot see
them, they are located on the retractor part of the safety
belts. They help the safety belts reduce a person’s
forward movement in a moderate to severe frontal, near
frontal or side crash or a rollover.
Pretensioners work only once. If they activate in a
crash, you will need to get new ones, and probably other
new parts for your safety belt system. SeeReplacing
Restraint System Parts After a Crash on page 1-68.
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.
1-30
Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle’s safety belts.
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.
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.
1-31
{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.
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.
Also seeRear Safety Belt Comfort Guides for
Children and Small Adults on page 1-27.Ifthe
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
the belts provide.
1-32
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. 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.
