Vehicle Damage Warnings
Also, in this book you will find 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 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:
•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
•Engine Compartment Overview in Section 5

•Your vehicle is equipped with a crash sensing
and diagnostic module, which records information
about the frontal air bag system. The module
records information about the readiness of the
system, when the system commands air bag
inflation and driver’s safety belt usage at deployment.
The module also records speed, engine rpm,
brake and throttle data.
•Let only qualified technicians work on your air bag
systems. Improper service can mean that an air bag
system will not work properly. See your dealer for
service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, or an air
bag covering on a seatback, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right front
passenger’s air bag, or the air bag module and
seatback for a side impact air bag. Do not open
or break the air bag coverings.
Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the air
bag systems. To purchase a service manual, seeService
Publications Ordering Information on page 7-12.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected,
an air bag can still inate during improper
service. You can be injured if you are close
to an air bag when it inates. Avoid yellow
connectors. They are probably part of the air
bag system. Be sure to follow proper service
procedures, and make sure the person
performing work for you is qualied to do so.
The air bag systems do not need regular maintenance.

Section 2 Features and Controls
2-1

One key is used for the
ignition, the doors and
all other locks.
When a new vehicle is delivered, the dealer removes the
key tag and gives it to the first owner. The tag has a
code on it that tells your dealer how to make extra keys.For vehicle security, keep the key tag in a safe place and
also record the key number somewhere other than inside
of the vehicle. If you lose your key, you will be able to
have a new one made easily using the tag.
Your vehicle may have an electronic immobilizer
designed to protect your car against theft. If so, only
keys with the correct electronic code can be used
to start the vehicle. Even if a key has the same profile,
it will not start the engine if the electronic code is
incorrect. If you need a new key, contact your dealer
who can obtain the correct key code. SeeRoadside
Assistance Program on page 7-6for more information.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.

Remote Keyless Entry System
Operation
The following functions
are available on your
vehicle’s remote keyless
entry system:
n(Lock/Unlock):Press this button to lock all of the
doors. If all of the doors and the trunk are closed, the
hazard lamps will flash once and the horn will chirp to
indicate that locking has occurred and the theft-deterrent
system will activate.
Press the button again to unlock all of the doors. The
hazard lamps will flash twice to indicate that unlocking
has occurred and the theft-deterrent system will
deactivate.If the door is not opened or if the engine is not started
within 30 seconds after unlocking the doors with the
transmitter, all of the doors will automatically lock and the
theft-deterrent system will re-activate.
V(Trunk):Press this button to unlock the trunk. The
horn will chirp twice to indicate that the trunk is unlocked.
The LED on the transmitter will flash when the buttons
on the transmitter are pressed.
The lock/unlock and trunk buttons will not operate and
the theft-deterrent system will not activate while the
key is in the ignition.
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 a maximum of
two transmitters matched to it.
2-5

Leaving Your Vehicle
If you are leaving your vehicle, take your keys. All of
the doors, except for the driver’s door, can be locked
from the outside by pushing down the door lock and then
closing the door. The driver’s door can only be locked
from the outside by using the key or the remote keyless
entry transmitter.
Trunk
To unlock the trunk from the outside, insert the key and
turn the trunk lock cylinder or use the remote keyless
entry transmitter.
When closing the trunk, close from the center to ensure
it fully latches. Although you may use one hand to
unlock the trunk, it is recommended that two hands on
the upper surface be used to close the trunk.
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can not see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-29.

30 seconds. The system will then lock the doors and
reactivate the theft-deterrent system.
How to Detect a Tamper Condition
If the hazard lamps flash once when the lock/unlock
button on the remote keyless entry transmitter is
pressed, the theft-deterrent system alarm was activated
while you were away.

use this equipment.
Immobilizer Operation
Your vehicle may have a passive theft-deterrent system.
The immobilizer system prevents your vehicle from
being started by unauthorized persons.
If your vehicle has an immobilizer system, your vehicle
has a special key that works with the theft-deterrent
system. There is a transponder in the key head that is
electronically coded. The correct key will start the
vehicle. An invalid key immobilizes the engine. The
immobilizer system isolates the power supply to
the ignition system, the fuel pump and the fuel injectors.
The engine immobilizer is activated after the key is turned
to LOCK and removed from the ignition. The security light
located on the top center of the instrument panel, near
the windshield, will flash when the immobilizer is active. If
the light does not flash after removing the key, have the
system checked by your dealer.
The immobilizer system works when you turn the key to
START. If the immobilizer system does not recognize the
electronic code, the engine will not start and the security
indicator will continue blinking. If your key is ever
damaged, you may not be able to start your vehicle.
