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 1-27
orInfants and Young Children on page 1-29. 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 which may turn off the passenger’s frontal
airbag. If this happens unintentionally, 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.
Rear Seat Passenger Positions
Lap-Shoulder Belt
The rear seat passenger 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.
1-22

The safety belt also locks if you pull the belt very
quickly out of the retractor.
{CAUTION:
You can be seriously hurt if your shoulder belt
is too loose. In a crash, you would move
forward too much, which could increase injury.
The shoulder belt should t against your body.
To unlatch the belt, just push the button on the buckle.
Rear Safety Belt Comfort Guides for
Children and Small Adults
Rear seat comfort guides provide added safety belt
comfort for older children who have outgrown booster
seats and for small adults. When installed on a shoulder
belt, the comfort guide better positions the belt away from
the neck and head.
There is one guide for each outside passenger in the rear
seat. Here is how to install a comfort guide and use the
safety belt:
1. Remove the guide from its storage clip on the
interior body.
1-24

4. Buckle, position and release the safety belt as
described inRear Seat Passengers on page 1-22.
Make sure that the shoulder belt crosses the
shoulder.
To remove and store the comfort guides, squeeze the
belt edges together so that you can take them out of the
guides. Slide the guide onto the storage clip.
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.
1-26

Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle’s safety belts.
If you have the choice, a child should sit in a seat that
has a lap-shoulder belt to get the additional restraint
a shoulder belt can provide.
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.
1-27

{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:Move the child toward the center of the vehicle, but
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.
If the child is sitting in a rear seat outside position,
seeRear Safety Belt Comfort Guides for Children
and Small Adults on page 1-24.
If the child is so small that the shoulder belt is still
very close to the child’s face or neck, you might
want to place the child in a seat that has a lap belt,
if your vehicle has one.
