How to Use this Manual
Many people read their owner’s manual from beginning
to end when they first receive their new vehicle. If you
do this, it will help you learn about the features and
controls for your vehicle. In this manual, you’ll find
that pictures and words work together to explain
things quickly.
Safety Warnings and Symbols
You will find a number of safety cautions in this book.
We use a box and the word CAUTION to tell you
about things that could hurt you if you were to ignore
the warning.
CAUTION:
These mean there is something that could hurt
you or other people.
In the caution area, we tell you what the hazard is.
Then we tell you what to do to help avoid or reduce
the hazard. Please read these cautions. If you don’t,
you or others could be hurt.
You will also find a circle
with a slash through it in
this book. This safety
symbol means “Don’t,”
“Don’t do this” or “Don’t
let this happen.”

iv
Vehicle Damage Warnings
Also, in this book you will find these notices:
NOTICE:
These mean there is something that could damage
your vehicle.
In the notice area, we 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 may be equipped with 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
specific component, control, message, gage or indicator.

component, gage or indicator reference the following
topics in the Index:

Seats and Seat Controls
This section tells you about the seats -- how to adjust
them, and fold them up and down. It also tells you about
reclining front seatbacks and head restraints.
Manual Front Seat
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.
If your vehicle has a manual bucket or a split bench seat,
you can adjust it with this lever located at the front of
the seat.
Lift the lever to unlock the seat. Using your body, slide
the seat to where you want it, and release the lever. Try
to move the seat with your body to make sure the seat is
locked into place.
