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

What Will You See After an Airbag
Inates?
After a frontal airbag inates, it quickly deates, so
quickly that some people may not even realize the
airbag inated. Roof-mounted side impact airbags
may still be at least partially inated minutes after
the vehicle comes to rest. Some components of the
airbag module — the steering wheel hub for the
driver’s airbag, the instrument panel for the right
front passenger’s airbag, or the ceiling of your
vehicle near the side windows for vehicles with
roof–mounted side impact airbags — may be hot for
a short time. The parts of the airbag that come into
contact with you may be warm, but not too hot to
touch. There may be some smoke and dust coming
from the vents in the deated airbags. Airbag
ination does not prevent the driver from seeing out
of the windshield or being able to steer the vehicle,
nor does it prevent people from leaving the vehicle.
{CAUTION:
When an airbag inates, there may be
dust in the air. This dust could cause
breathing problems for people with a
history of asthma or other breathing
trouble. To avoid this, everyone in the
vehicle should get out as soon as it is
safe to do so. If you have breathing
problems but cannot get out of the vehicle
after an airbag inates, then get fresh air
by opening a window or a door. If you
experience breathing problems following
an airbag deployment, you should seek
medical attention.
Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on, and
turn on the hazard warning ashers when the
airbags inate. You can lock the doors again, turn
the interior lamps off, and turn the hazard warning
ashers off by using the controls for those features.

/(Remote Start):If your vehicle has the remote
start feature, the RKE transmitter will have a
button with this symbol on it.
To start the vehicle using the remote start feature,
do the following:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock
button, then immediately press and hold
the transmitter’s remote start button for four
seconds or until the turn signal lamps
ash. The vehicle’s doors will lock.
3. When the vehicle’s engine starts, the parking
lamps will turn on and remain on while the
engine is running.
The engine will shut off automatically after
10 minutes, unless a time extension has been
done or the vehicle’s key is inserted into
the ignition switch and turned to RUN.
If you enter the vehicle after a remote start,
and the engine is still running, insert the
key into the ignition switch and turn it to RUN
to drive the vehicle.4. To manually shut off a remote start, do any of
the following. The parking lamps will turn off:
Aim the RKE transmitter at the vehicle
and press the remote start button.
Turn on the hazard warning ashers.
Turn the ignition switch to RUN and
then to OFF.
Your vehicle’s engine may be started two times
using the transmitter’s remote start feature. If only
one remote start procedure has been done,
since last driving the vehicle, or resetting the
remote start system, the engine may be started
again remotely following the remote start
procedure a second time
If the remote start procedure is used again before
the rst 10 minute time frame has ended, the
rst 10 minutes will immediately expire and
the second 10 minute time frame will start.
94

The remote vehicle start feature will not operate if
any of the follow occur:
The remote start system is disabled through
the DIC.
The vehicle’s key is in the ignition.
A door on the vehicle is open.
The vehicle’s hood is open.
The hazard warning ashers are on.
The check engine light is on. SeeMalfunction
Indicator Lamp on page 190.
The engine coolant temperature is too high.
The oil pressure is low.
Two remote vehicle starts have already been
provided for that ignition cycle.
If a remote start is attempted and is unsuccessful,
the Driver Information Center (DIC) will display
REMOTE START DISABLED.Vehicles that have the remote vehicle start feature
are shipped from the factory with the remote
vehicle start system enabled. The system may be
enabled or disabled through the DIC. See
“REMOTE START” underDIC Vehicle
Personalization on page 229for additional
information. If your vehicle does not have the DIC
feature, and remote vehicle start was installed
at the dealership, you will need to have the
dealership enable or disable the system.
Remote Start Ready
If your vehicle does not have the remote vehicle
start feature, it may have the remote start
ready feature. This feature gives you the ability to
lock or unlock your vehicle from about 492 feet
(150 m) away and allows your dealer to add
the manufacturer’s remote vehicle start feature.
See your dealer if you would like to add the
manufacturer’s remote vehicle start feature to
your vehicle.

Power Door Locks
To lock or unlock all
doors from inside the
vehicle, use the
power door lock switch
located on either
front door armrest.
Press the bottom of the switch to lock all doors.
Press the top of the switch to unlock all doors.
The driver’s and front passenger’s power door lock
switch also releases the trunk lid. Press the top
of the switch for about one and a half seconds to
open the trunk.
If the vehicle has the content theft-deterrent
system, the vehicle is programmed to arm the
system with the power door lock switch. If your
vehicle has a Driver Information Center (DIC) this
feature can be turned off. See “Content Theft”
underDIC Vehicle Personalization on page 229.
Delayed Locking
Your vehicle may have this feature. It delays the
locking of the vehicle’s doors for ve seconds after
the last door is closed. Two chimes will sound
when the power door lock switch or the LOCK
button on the remote keyless entry transmitter is
pressed when a door is open. The chimes indicate
that the delayed locking feature is on. If your
vehicle has a Driver Information Center (DIC), a
Delayed Locking warning will be displayed.
The doors can be locked immediately by pressing
the power door lock switch or the LOCK button
on the transmitter a second time.
The delayed locking feature will not activate when
the ignition is in RUN or ACCESSORY.
You can program this feature on or off through the
Driver Information Center (DIC), if equipped.
See “Delayed Locking” underDIC Vehicle
Personalization on page 229.

PASS-Key®III Operation
Your vehicle is equipped
with PASS-Key®III
(Personalized
Automotive Security
System) theft-deterrent
system.
PASS-Key
®III is a passive theft-deterrent system.
This means nothing special needs to be done
to arm or disarm the system. It works when the key
is inserted or removed from the ignition.
PASS-Key III
®uses a transponder in the ignition
key that matches a decoder in the vehicle.
When the PASS-Key
®III system senses that the
wrong key has been inserted into the ignition, it
shuts down the vehicle’s starter and fuel systems.The starter will not work and fuel will stop owing to
the engine. If someone tries to start the vehicle
again with the wrong key, the vehicle will not start.
Anyone using a trial-and-error method to start the
vehicle will be discouraged to do so because of the
high number of electrical key codes.
When trying to start the vehicle, if the engine does
not start and the STARTING DISABLED warning
message on the Driver Information Center
(DIC) comes on, the key may have a damaged
transponder. Turn the ignition off and try again.
If the engine still does not start, and the key
appears to be undamaged, try another ignition
key. At this time, you may also want to check the
fuse. SeeFuses and Circuit Breakers on
page 450. If the engine still does not start with the
other key, the vehicle needs service. If the
vehicle does start, the rst key may be faulty. See
your dealer who can service the PASS-Key
®III
to have a new key made. In an emergency,
contact Roadside Assistance. SeeRoadside
Assistance Program on page 484for more
information.
107

It is possible for the PASS-Key®III decoder to
accept the transponder value of a new or
replacement key. Up to 10 keys may be
programmed for the vehicle. The following
procedure is for programming additional keys only.
If all the programmed keys are lost or do not
operate, see your dealer or a locksmith who can
service PASS-Key
®III to have keys made and
programmed to the system.
To program the new key do the following:
1. Verify that the new key has PK3 stamped
on it.
2. Insert the master key in the ignition and start
the engine. If the engine will not start, see
your dealer for service.
3. After the engine has started, turn the key to
OFF, and remove the key.
4. Insert the key to be programmed and turn it to
RUN within ve seconds of removing the
original key.5. The SERVICE THEFT SYSTEM warning
message on the DIC will turn off, once the
key has been programmed. It may not
be apparent that the SERVICE THEFT
SYSTEM warning message went on due to
how quickly the key is programmed.
6. Repeat Steps 1 through 5 if additional keys
are to be programmed.
If the SERVICE THEFT SYSTEM warning
message appears and stays on the DIC while the
vehicle is being driven, the engine will be able
to be restarted if it is turned off. Your
PASS-Key
®III system, however, is not working
properly and must be serviced by your dealer.
The vehicle is not protected by the PASS-Key
®III
system at this time.
If the PASS-Key
®III key is lost or stolen, see your
dealer or a locksmith who can service
PASS-Key
®III to have a new key made.

on page 208for more information.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 transaxle. Also, always remember
to lock the doors.
The battery could be drained if you leave the key
in the ignition while your vehicle is parked.
You may not be able to start your vehicle after it
has been parked for an extended period of time.
