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

Section 2 Features and Controls
2-1

Remote Vehicle Start
Your vehicle may have a remote starting feature. This
feature allows you to start the engine from outside
the vehicle. It may also start the vehicle’s heating or air
conditioning systems, rear window defogger, and
heated seats. SeeHeated Seats on page 1-4and
Heated and Cooled Seats on page 1-5for additional
information. When the remote start system is active, the
climate control system will heat and cool the inside of
the vehicle based on the outside temperature. The rear
window defogger will be turned on by the climate
control system when it is heating the inside of the
vehicle. If the vehicle has heated seats, they may also
turn on. Cooled seats are not activated during a
remote start. Normal operation of the system will return
after the key is turned to the RUN position.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using the remote start to have the vehicle in
view when doing so. Check local regulations for
any requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
If your vehicle has remote start, the keyless entry
transmitter provides, an increased range of operation.
However, the range may be less while the vehicle
is running. As a result, you may need to be closer to
your vehicle to turn it off, than you were to turn it on.There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry System on page 2-5for additional information.
/(Remote Start):Press and release the lock button
and then press and hold the remote start button to
start the vehicle.
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 until the turn signal lights
ash or if the vehicle’s lights are not visible, press
and hold the remote start button for at least
four seconds. The vehicle’s doors will lock. Pressing
the remote start button again after the vehicle
has started will turn off the ignition.
3. When the vehicle starts, the parking lamps will turn
on and remain on while the vehicle is running.
4. If it is your rst remote start since last driving,
repeat these steps while the engine is still
running for a 10 minute time extension. Remote
start can be extended one time.
2-9

When you enter the vehicle during a remote start, and
the engine is still running, turn the key to the RUN
position to drive the vehicle. If the vehicle is left running
it will automatically shut off after 10 minutes unless a
time extension has been done.
To manually shut off a remote start, do any of the
following:
Aim the remote keyless entry transmitter at the
vehicle and press the remote start button until
the parking lamps turn off.
Turn on the hazard warning ashers.
Turn the ignition switch on and then off.
The vehicle can be started remotely two separate times
between driving sequences. The engine will run for
10 minutes after each remote start.
Or, you can extend the engine run time by another
10 minutes within the rst 10 minute remote start time
frame, and before the engine stops.
For example, if the lock button and then the remote
start buttons are pressed again after the vehicle
has been running for ve minutes, 10 minutes are
added, allowing the engine to run for 15 minutes.The additional 10 minutes are considered a second
remote vehicle start.
Once two remote starts, or a single remote start with
one time extension have been done, the vehicle must be
started with the key.
After the key is removed from the ignition, another
remote start can be performed.
The vehicle cannot be started remotely if the key is in
the ignition, the hood is not closed, or if there is an
emission control system malfunction.Remote Start Ready
If your vehicle does not have the remote vehicle start
feature, it may have the remote start ready feature. This
feature allows your dealer to add the manufacturer’s
remote vehicle start feature.
If your vehicle has the remote start ready feature, your
remote keyless entry transmitter will have extended
range that will allow you to lock or unlock your vehicle
from approximately 195 feet (60 m) away.
See your dealer if you would like to add the
manufacturer’s remote vehicle start feature to your
vehicle.
2-10

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, if the vehicle has one, the power
door lock switch, or by lifting the rear door
manual lock.
2. Open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert the key into the security lock slot and turn it
so the slot is in the vertical position.
Lockout Protection
If the key is in the ignition and the power door lock
switch is used to lock the doors, all doors will lock and
then the driver’s door will unlock. It is always
recommended that you remove the ignition key when
locking your vehicle.
The lockout protection feature can be overridden by
holding the power door lock switch for three seconds or
longer.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot 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.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-31.
2-14

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 you do not have to
do anything special to arm or disarm the system. It
works when you insert or remove the key from
the ignition.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.
When trying to start the vehicle if the engine does not
start and the security light on the instrument panel
cluster 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 not damaged, try another ignition key. At this
time, you may also want to check the fuse, seeFuses
and Circuit Breakers on page 5-93. If the engine
still does not start with the other key, your vehicle needs
service. If your 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 7-6.
It is possible for the PASS-Key
®III+ decoder to “learn”
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 currently programmed keys are lost
or do not operate, you must see your dealer or a
locksmith who can service PASS-Key
®III+ to have keys
made and programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the system.
2-20

To program the new key do the following:
1. Verify that the new key has a
1stamped on it.
2. Insert the already programmed 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 the
RUN position within ve seconds of the original key
being turned to the OFF position.
5. The security light will turn off once the key has
been programmed.
6. Repeat Steps 1 through 5 if additional keys are to
be programmed.
If you are ever driving and the security light comes on
and stays on, you may be able to restart your engine if
you turn it off. Your PASS-Key
®III+ system, however,
is not working properly and must be serviced by
your dealer. Your vehicle is not protected by the
PASS-Key
®III+ system at this time.
If you lose or damage your PASS-Key
®III+ key, see
your dealer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake, or slow, the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new
brake linings are not yet broken in. Hard stops
with new linings can mean premature wear
and earlier replacement. Follow this breaking-in
guideline every time you get new brake
linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 4-36for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
2-21

Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
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 in all the way. If
none of this works, then your vehicle needs service.
A (OFF):This is the only position in which the ignition
key can be inserted or removed. This position locks
the ignition and transaxle. It is a theft-deterrent feature.B (ACCESSORY):This position lets the radio and
windshield wipers operate while the engine is off. To use
ACCESSORY, turn the key clockwise.
C (RUN):This position is where the key returns to after
the vehicle is started. This position displays some of
the warning and indicator lights.
D (START):This position starts the engine.
A warning chime will sound and the Driver Information
Center (DIC) will display DRIVER’S DOOR OPEN when
the driver’s door is opened if the ignition is in OFF,
ACCESSORY and the key is in the ignition. SeeDIC
Warnings and Messages on page 3-56for more
information.
Retained Accessory Power (RAP)
After you turn the ignition off and remove the key, you
will still have power to such accessories as the
power windows, clock, radio, and if the vehicle has
them, audio steering wheel controls and sunroof. The
power to the accessories can last up to 10 minutes. The
instrument panel cluster lights will stay on for a few
seconds, then will go out. Once you open a door, the
power will shut off. Your vehicle has a feature designed
to protect the battery against drainage. For more
information seeInadvertent Power Battery Saver on
page 3-18.
2-22

Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
The engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as the
engine gets warm.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.2. If the engine does not start within 10 seconds, hold
your key in START for about 10 seconds at a time
until the engine starts. Wait about 15 seconds
between each try.
When your engine has run for about 10 seconds to
warm up, your vehicle is ready to be driven. Do
not race your engine when it is cold.
If the weather is below freezing (32°F or 0°C), let
the engine run for a few minutes to warm up.
3. If your engine still will not start, or starts but then
stops, it could be ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
oor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
briey but then stops again, do the same thing.
This time keep the pedal down for ve or six
seconds to clear the extra gasoline from the engine.
After waiting about 15 seconds, repeat the normal
starting procedure.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.
2-23

Engine Coolant Heater
If your vehicle has this feature, in very cold weather, 0°F
(−18°C) or colder, the engine coolant heater can help.
You’ll get easier starting and better fuel economy during
engine warm-up. Usually, the coolant heater should be
plugged in a minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of the
coolant heater is not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
On vehicles with the 3.8L V6 engine, the coolant
heater cord is located on the passenger’s side of the
vehicle, above the headlamp assembly. On
vehicles with the 4.6L V8 engine, the cord is located
on the driver’s side of the vehicle on the right
side of the engine air cleaner. It is between the
engine cover and the engine air cleaner.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
3. Plug the cord into a normal, grounded 110-volt AC
outlet.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.
