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, see
Older Children on page 48orInfants and Young
Children on page 51. 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.

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 30.
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, let
the belt go back all the way and start again.

Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the
driver and right front passenger. Although you
cannot see them, they are part of the safety belt
assembly. They help tighten the safety belts during
the early stages of a moderate to severe frontal,
near frontal or side crash or a rollover if the
threshold conditions for pretensioner activation
are met.
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 93.
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/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.
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.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
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.

Page 49 of 554
{CAUTION:
Never do this.
Here two children are wearing the same
belt. The belt cannot 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 on page 43. 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.

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.{CAUTION:
Children can be seriously injured or
strangled if a shoulder belt is wrapped
around their neck and the safety belt
continues to tighten. Never leave children
unattended in a vehicle and never allow
children to play with the safety belts.
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.
