Your vehicle has a light that
comes
on as a reminder to
buckle
up. (See “Safety
Belt Reminder Light”
in
the Index.)
In most states and Canadian provinces, the law says to
wear safety belts. Here’s why:
They work.
You never know if you’ll be in a crash. If you do have a
crash, you don’t know
if it will be a bad one.
A few crashes are mild, and some crashes can be so
serious that even buckled up a person wouldn’t survive.
But most crashes are in between. In many
of them,
people who buckle up can survive and sometimes walk
away. Without belts they could have been badly hurt
or killed.
After more than
30 years of safety belts in vehicles, the
facts are clear.
In most crashes buckling up does
matter
... a lot!
Why Safety Belts Work
When you ride in or on anything, you go as fast as
it goes.

Take the simplest vehicle. Suppose it’s just a seat
on wheels.

Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here’s how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat (to see how, see “Seats” in the Index)
so you can sit up straight.
3. Pick up the latch plate and pull the belt across you.
Don’t 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 isn’t long enough, see “Safety Belt
Extender’’ at the end
of this section.
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.

r-
Children who ar ~p against, or very close to, an
air bag when it inflates can be seriously injured
or killed. This is true even though your vehicle
has reduced-force frontal air bags.
Air bags plus
lap-shoulder belts offer the best protection for
adults, but not for young children and infants.
Neither the vehicle’s safety belt system nor its air
bag system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle.
To read how,
see the part of this manual called “Children” and
see the caution labels on the sunvisors and the
right front passenger’s safety belt.
There is an air bag readiness
light
on the instrument
panel, which shows the air
bag symbol.
The system checks the air bag electrical system for
malfunctions. The light tells
you if there is an electrical
problem. See “Air
Bag Readiness Light” in the Index
for
more information.

Rear Seat Passengers
It's 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 aren't 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
The positions next to the windows have lap-shoulder
belts. Here's how
to wear one properly.
Rear Seat Outside Passenger Positions
I. Pick up the latch plate and pull the belt across you.
Don't 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.

Safety Belt Extender
If the vehicle’s safety belt will fasten around you, you
should use it.
But if a safety belt isn’t long enough to fasten, your
dealer will order you an extender. It’s free. When
you go
in to order it, take the heaviest coat you will wear, so the
extender will be long enough for you. The extender will
be just for
you, and just for the seat in your vehicle that
you choose. Don’t let someone else use it, and use it
only for the seat it
is made to fit. To wear it, just attach it
to the regular safety belt.
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors and
anchorages are working properly.
Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from
doing its job, have it repaired.
Torn or frayed safety belts may not protect
you in a
crash. They can rip apart under impact forces.
If a belt is
torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

Remote Panic Alarm
When the button with the horn symbol on the key
transmitter is pressed, the horn will sound and
the
headlamps and taillamps will flash for up to 30 seconds.
This can be turned off by pressing the horn button again,
waiting for
30 seconds, or starting the vehicle.
Matching Transmitter(s) To Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If
a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember
to bring any
remaining transmitters with you
when you go to your
dealer. When the dealer matches the replacement
transmitter
to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded
the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have only four transmitters
matched to it.
