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.
If you need help figuring out a specific name of a
component, gage or indicator reference the following
topics in the Index:
D “Engine Compartment Overview”
D “Instrument Panel”
D “Comfort Controls”
D “Audio Systems”
Also see “Warning Lights and Gages” in the Index.

This section tells you about the seats -- how to adjust
them, and fold them up and down. It also tells you about

seats with the horizontal control located on the outboard
edge of each front seat.

of the control.
Move the seat forward or rearward by moving the

the vehicle.

The memory function can recall preset positions for the

To set your memory seat do the following:
1. Adjust the driver’s seat to the desired position.
2. Press the SET button and then press the 1 or 2 button
of the memory control within five seconds.
When your vehicle is in PARK (P), press the same
