Vehicle Damage Warnings
Also, in this book you will ®nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly. But the
notice will tell you what to do to help avoid the
damage.
When you read other manuals, you might see CAUTION
and NOTICE warnings in different colors or in different
words.
You'll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a speci®c component, control,
message, gage or indicator.
If you need help ®guring out a speci®c name of a
component, gage or indicator, reference the following
topics:
·Seats and Restraint Systems in Section 1

·Instrument Panel Overview in Section 3

Front Seats
Manual Seats
{CAUTION:
You can lose control of the vehicle if you try to
adjust a manual driver's seat while the vehicle
is moving. The sudden movement could startle
and confuse you, or make you push a pedal
when you don't want to. Adjust the driver's
seat only when the vehicle is not moving.
Lift the lever located on the front of the driver's seat to
unlock it. Slide the seat to where you want it and
release the lever. Then try to move the seat with your
body, to make sure the seat is locked into place.

Your vehicle will be equipped with one of the following
passenger seat adjusters.
If your vehicle is not equipped with easy entry seats,
your passenger seat adjuster looks like this. Slide
the lever located under the passenger's seat to the right
to unlock it. Slide the seat to where you want it and
release the lever. Then try to move the seat with your
body, to make sure the seat is locked into place.If your vehicle is equipped with easy entry seats, this is
your front passenger seat adjuster. Pull up on the
lever located at the front of the passenger's seat up to
unlock it. Slide the seat to a comfortable position
and release the lever. Then try to move the seat with
your body, to make sure the seat is locked into place.

Rear Seats
Rear Seat Operation
Folding the Seatback
To fold the seatback, do the following:
1. Pull the release straps
located in the trunk.
The right strap
operates the
passenger's side rear
split seat. The left
strap operates
the driver's side rear
split seat.
2. Fold the seatback down from the inside of the
vehicle.
{CAUTION:
If the seatback isn't locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
press rearward on the seatback to be sure it is
locked.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted won't provide the
protection needed in a crash. The person
wearing the belt could be seriously injured.
After raising the rear seatback, always check
to be sure that the safety belts are properly
routed and attached, and are not twisted.
To raise the seatback, push the seatback up to return it
to its original position.
Push and pull on the seatback to make sure it is latched
securely in the fully upright position.

Safety Belts
Safety Belts: They Are for Everyone
This part of the manual tells you how to use safety
belts properly. It also tells you some things you should
not do with safety belts.
{CAUTION:
Don't let anyone ride where he or she can't
wear a safety belt properly. If you are in a
crash and you're not wearing a safety belt,
your injuries can be much worse. You can hit
things inside the vehicle or be ejected from it.
You can be seriously injured or killed. In the
same crash, you might not be, if you are
buckled up. Always fasten your safety belt,
and check that your passengers' belts are
fastened properly too.
{CAUTION:
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are more
likely to be seriously injured or killed. Do not
allow people to ride in any area of your vehicle
that is not equipped with seats and safety
belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.
Your vehicle has a light
that comes on as a
reminder to buckle up. See
Safety Belt Reminder
Light on page 3-24.
In most states and in all Canadian provinces, the law
says to wear safety belts. Here's why:
They work.

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 so you can sit up straight. To see
how, see ªSeatsº in the Index.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 on page 1-28.
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.
