manufacturer’s remote vehicle start feature to
your vehicle.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can easily
open the doors and fall out of a moving
vehicle. When a door is locked, the handle
will not open it. You increase the chance of
being thrown out of the vehicle in a crash if
the doors are not locked. So, wear safety
belts properly and lock the doors whenever
you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
CAUTION: (Continued)

the power door lock switch of either the driver’s or front
passenger’s door is used to lock the vehicle. The door
needs to be in the open position when pressing the power
door lock switch. The alarm system will not activate if
the door is closed when the power door lock switch is
pressed. This system can be activated through the Driver
Information Center (DIC). See “CONTENT THEFT”
under “Customization Menu Items” inDIC Vehicle
Personalization on page 3-75.
When the doors are locked using the power door lock
switch of either front door, the red light on top of the
instrument panel will start ashing at a fast rate,
indicating that the system is arming. After all the doors
are locked there will be a time delay and then the red light
will begin to ash at a very slow rate, indicating the
system is armed.

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 5-93. 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 7-6for more information.
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.
2-21

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.
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 4-38for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
2-22

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 3-59for more
information.
Retained Accessory Power (RAP)
If the vehicle has Retained Accessory Power (RAP),
certain features will continue to operate for up to
10 minutes after the ignition key is turned to OFF
unless a door is opened.
