How to Use This Manual
Many people read the owner manual from
beginning to end when they rst receive their new
vehicle. If this is done, it can help you learn
about the features and controls for the vehicle.
Pictures and words work together in the
owner manual to explain things.
Index
A good place to quickly locate information about
the vehicle is the Index in the back of the manual.
It is an alphabetical list of what is in the manual
and the page number where it can be found.
Safety Warnings and Symbols
There are a number of safety cautions in this
book. We use a box and the word CAUTION to
tell 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 do not, you or others could be hurt.
You will also nd a
circle with a slash
through it in this book.
This safety symbol
means “Do Not,”
“Do Not do this” or
“Do Not let this happen.”

Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something
that could damage your vehicle.
A notice tells about something that can damage
the vehicle. Many times, this damage would not be
covered by your vehicle’s warranty, and it could
be costly. But the notice will tell 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.
There are also warning labels on the vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown
along with the text describing the operation or
information relating to a specic component,
control, message, gage, or indicator.
If you need help guring out a specic name of
a component, gage, or indicator, reference
the following topics:
Seats and Restraint Systems in Section 1
Features and Controls in Section 2
Instrument Panel Overview in Section 3
Climate Controls in Section 3
Warning Lights, Gages, and Indicators in
Section 3
Audio System(s) in Section 3

Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on, and
ash the hazard warning ashers when the airbags
inate. You can lock the doors again, turn the
interior lamps off, and turn off the hazard warning
ashers by using the controls for those features.
In many crashes severe enough to inate the
airbag, windshields are broken by vehicle
deformation. Additional windshield breakage may
also occur from the right front passenger airbag.
Airbags are designed to inate only once.
After an airbag inates, you will need some new
parts for your airbag system. If you do not get
them, the airbag system will not be there to help
protect you in another crash. A new system
will include airbag modules and possibly other
parts. The service manual for your vehicle
covers the need to replace other parts.
Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Collection
and Event Data Recorders on page 458.
Let only qualied technicians work on the
airbag system. Improper service can mean
that an airbag system will not work properly.
See your dealer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system for
the right front passenger’s position. A passenger
airbag status indicator on the instrument panel
will be visible when you turn your ignition key
to ON or START.
The words ON and OFF or the symbol for on
and off, will be visible on the instrument panel
during the system check. When the system check
is complete, either the word ON or the word
OFF, or the symbol for on or the symbol for off
will be visible. SeePassenger Airbag Status
Indicator on page 179.

Notice:Using a tool to force the key from the
ignition switch could cause damage or break
the key. Use the correct key and turn the key
only with your hand. Make sure the key is all the
way in. If it is, turn the steering wheel left and
right while you turn the key hard. If none of this
works, then your vehicle needs service.
ACC (ACCESSORY) (B):This is the position in
which you can operate your electrical accessories
or items plugged into the accessory power
outlets. On automatic transmission vehicles, this
position unlocks the ignition. On manual
transmission vehicles, it unlocks the ignition and
steering wheel. Use this position if your vehicle
must be pushed or towed.
ON (C):This is the position that the switch returns
to after you start your engine and release the
switch. The switch stays in ON when the engine is
running. But even when the engine is not running,
you can use ON to operate the electrical
accessories and to display some instrument
panel cluster warning and indicator lights.The transmission is also unlocked in this position on
automatic transmission vehicles.
The battery could be drained if you leave the key in
the ACC or ON position with the engine off. You
may not be able to start your vehicle if the battery is
allowed to drain for an extended period of time.
START (D):This is the position that starts the
engine. When the engine starts, release the key.
The ignition switch returns to ON for driving.
When the engine is not running, ACC and ON
allows you to operate the electrical accessories,
such as the radio or items plugged into the
accessory power outlets.
A warning tone will sound if you open the driver’s
door when the ignition is in ACC or LOCK and
the key is in the ignition.
Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transmission. Also, always
remember to lock the doors.
