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.

Automatic Transaxle Operation
Your automatic transaxle has a shift lever located on
the steering column.
PARK (P):This position locks your front wheels. It is
the best position to use when you start your engine
because your vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
CAUTION: (Continued)
CAUTION: (Continued)
You or others could be injured. To be sure
your vehicle will not move, even when you are
on fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
SeeShifting Into Park (P) on page 2-29.Ifyou
are pulling a trailer, seeTowing a Trailer on
page 4-36.
Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transaxle
shift lock control system. You have to fully apply
your regular brakes before you can shift from PARK (P)
while the ignition is in RUN. If you cannot shift out of
PARK (P), ease pressure on the shift lever and push the
shift lever all the way into PARK (P) as you maintain
brake application. Then move the shift lever into
the gear you want. SeeShifting Out of Park (P) on
page 2-30.

Parking Brake
The parking brake pedal is
located to the left of the
regular brake pedal,
near the driver’s door.
To set the parking brake, hold the regular brake pedal
down with your right foot and push the parking brake
pedal down with your left foot.If the ignition is on, the brake system warning light on
the instrument panel cluster should come on. If it
does not, you need to have your vehicle serviced.
To release the parking brake, hold the regular brake
pedal down with your right foot and push the parking
brake pedal down with your left foot. When you lift your
left foot, the parking brake pedal will follow it to the
released position.
A warning chime will sound if the parking brake is set,
the ignition is on, and the vehicle speed is greater
than 5 mph (8 km/h). The brake light will come on and
stay on until the parking brake is released. See
Brake System Warning Light on page 3-40for more
information.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-36.

Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle will
not move, even when you are on fairly level
ground, use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 4-36.
1. Hold the brake pedal down with your right foot and
set the parking brake.
2. Move the shift lever into PARK (P) by pulling the
shift lever toward you and moving the lever up as
far as it will go.
3. Turn the ignition key to OFF.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
Leaving Your Vehicle With the
Engine Running
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is rmly set before you leave it. After you
have moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move
the shift lever away from PARK (P) without rst pulling it
toward you. If you can, it means that the shift lever
was not fully locked into PARK (P).
