Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock or the
remote keyless entry system and close the
door. Wait 30 seconds until the security lamp
goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the hazard lights will ash.
You can turn off the alarm by unlocking the driver’s door
with your key, using the unlock button on the remote
keyless entry transmitter or by starting the car with
a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown. To
replace the fuse, seeFuses and Circuit Breakers on
page 5-93. If the fuse does not need to be replaced, you
may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.

the key that matches a decoder in your vehicle.
PASS-Key®III+ Operation
Your vehicle has 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 or transition the key
from run, accessory or start from the off position.

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 3-76for more
information.
Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the ignition key is turned
from RUN to OFF:
Radio
Power Windows
Audio Steering Wheel Controls
Sunroof
Power to these accessories stops after 10 minutes or
if a door is opened. If you want power for another
10 minutes, close all the doors and turn the ignition
key to RUN and then back to OFF.
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.
Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects the electrical system. If the
ignition key is turned to the START position,
and then released when the engine begins cranking,
the engine will continue cranking until the vehicle
starts or until it exceeds the maximum cranking time
allowed, approximately 15 seconds to prevent
cranking motor damage. To prevent starter-motor
gear damage, this system also prevents cranking if
the engine is already running. The engine cranking
can be stopped by turning the ignition switch to
the ACCESSORY or OFF position.

Universal Home Remote System
Operation
Do not use the Universal Home Remote with any
garage door opener that does not have the stop and
reverse feature. This includes any garage door opener
model manufactured before April 1, 1982. If you
have a newer garage door opener with rolling codes,
please be sure to follow Steps 6 through 8 to complete
the programming of your Universal Home Remote
Transmitter.
Read the instructions completely before attempting to
program the Universal Home Remote. Because of
the steps involved, it may be helpful to have another
person available to assist you in the programming steps.
Keep the original hand-held transmitter for use in
other vehicles as well as for future Universal Home
Remote programming. It is also recommended that upon
the sale of the vehicle, the programmed Universal
Home Remote buttons should be erased for security
purposes. See “Erasing Universal Home Remote
Buttons” later in this section or, for assistance, see
Customer Assistance Offices on page 7-4.
Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.Programming Universal Home Remote
Follow these steps to program up to three channels:
1. Press and hold down the two outside Universal
Home Remote buttons, releasing only when the
Universal Home Remote indicator light begins
to ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
hand-held transmitter to the remaining two Universal
Home Remote buttons.
2. Position the end of your hand-held transmitter
about 1 to 3 inches (3 to 8 cm) away from the
Universal Home Remote buttons while keeping the
indicator light in view.
3. Simultaneously press and hold both the desired
Universal Home Remote button and the hand-held
transmitter button. Do not release the buttons
until Step 4 has been completed.
Some entry gates and garage door openers may
require you to substitute Step 3 with the procedure
noted in “Gate Operator and Canadian
Programming” later in this section.
2-46

Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to time out or quit after several seconds of
transmission. This may not be long enough for Universal
Home Remote to pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured
to time out in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator or garage door opener
by using the “Programming Universal Home Remote”
procedures, regardless of where you live, replace Step 3
under “Programming Universal Home Remote” with
the following:
Continue to press and hold the Universal Home Remote
button while you press and release every two seconds
(cycle) the hand-held transmitter button until the
frequency signal has been successfully accepted by the
Universal Home Remote. The Universal Home Remote
indicator light will ash slowly at rst and then rapidly.
Proceed with Step 4 under “Programming Universal
Home Remote” to complete.
Using Universal Home Remote
Press and hold the appropriate Universal Home Remote
button for at least half of a second. The indicator light
will come on while the signal is being transmitted.
Erasing Universal Home Remote
Buttons
To erase programming from the three Universal Home
Remote buttons do the following:
1. Press and hold down the two outside buttons until
the indicator light begins to ash, after 20 seconds.
Do not hold the two outside buttons for longer
than 30 seconds.
2. Release both buttons.
The Universal Home Remote is now in the training
(learning) mode and can be programmed at any time
beginning with Step 2 under “Programming Universal
Home Remote” shown earlier in this section.
Individual buttons cannot be erased, but they can be
reprogrammed. See “Reprogramming a Single Universal
Home Remote Button” following this section.
