Manual Operation Override
This system offers a full complement of
manual override features. The AUTO symbol
in the front ATC display will be turned off
when the system is being used in the manual
mode.
Operating Tips
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to pro-
vide proper corrosion protection and to pro-
tect against engine overheating. OAT coolant
(conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and de-
froster performance, make sure the engine
cooling system is functioning properly and
the proper amount, type, and concentration
of coolant is used. Use of the Air Recircula-
tion mode during Winter months is not rec-
ommended, because it may cause window
fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for
about five minutes, in fresh air with the
blower setting on high. This will ensure ad-
equate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in
mild, rainy, and/or humid weather. To clear
the windows, select Defrost or Mix mode and
increase the front blower speed. Do not use
the Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstruc-
tions, such as leaves. Leaves collected in the
air intake may reduce airflow, and if they
enter the plenum, they could plug the water
drains. In Winter months, make sure the air
intake is clear of ice, slush, and snow.
Cabin Air Filter
The climate control system filters out dust
and pollen from the air. Contact an autho-
rized dealer to service your cabin air filter,
and to have it replaced when needed.

UNIVERSAL GARAGE DOOR OPENER
(HOMELINK)
• HomeLink replaces up to three hand-heldtransmitters that operate devices such as
garage door openers, motorized gates,
lighting or home security systems. The
HomeLink unit is powered by your vehicles
12 Volt battery. • The HomeLink buttons that are located in
the overhead console or sunvisor designate
the three different HomeLink channels.
• To operate HomeLink, push and release any of the programmed HomeLink buttons.
These buttons will activate the devices they
are programmed to with each press of the
corresponding HomeLink button.
Before You Begin Programming
HomeLink
For efficient programming and accurate
transmission of the radio-frequency signal, it
is recommended that a new battery be placed
in the hand-held transmitter of the device
that is being programmed to the HomeLink
system. Make sure your hand-held transmit-
ter is programmed to activate the device you
are trying to program your HomeLink button
to.
Ensure that your vehicle is parked outside of
the garage before you begin programming.
It is recommended that you erase all the
channels of your HomeLink before you use it
for the first time.

If you have any problems, or require assis-
tance, please call toll-free 1-800-355-3515
or, on the Internet at HomeLink.com for in-
formation or assistance.
Erasing All The HomeLink
Channels
To erase the channels, follow this procedure:
1. Place the ignition switch into the ON/RUNposition.
NOTE:
For vehicle’s equipped with Keyless
Enter-N-Go, place the ignition in the RUN
position with the Engine ON. Make sure to
program HomeLink with the vehicle out-
side of the garage, or with the garage door
open at all times.
2.
Push and hold the two outside HomeLink
buttons (I and III) for up to 20 seconds, or
until the instrument cluster display
switches from the “Clearing Channels”
message to the “Channels Cleared”
message.
NOTE:
Erasing all channels should only be per-
formed when programming HomeLink for the
first time. Do not erase channels when pro-
gramming additional buttons.
Identifying Whether You Have A
Rolling Code Or Non-Rolling Code
Device
Before programming a device to one of your
HomeLink buttons, you must determine
whether the device has a rolling code or
non-rolling code.
Rolling Code Devices
To determine if your device has a rolling code,
a good indicator is its manufacturing date.
Typically, devices manufactured after
1995 have rolling codes. A device with a
rolling code will also have a “LEARN” or
“TRAIN” button located where the antenna is
attached to the device. The button may not
be immediately visible when looking at the
device. The name and color of the button may
vary slightly by manufacturer. NOTE:
The “LEARN” or “TRAIN” button is not the
button you normally use to operate the de-
vice.
Non-rolling Code Devices
Most devices manufactured before 1995 will
not have a rolling code. These devices will
also not have a “LEARN” or “TRAIN” button.Programming HomeLink To A
Garage Door Opener
To program any of the HomeLink buttons to
activate your garage door opener motor, fol-
low the steps below:
NOTE:
All HomeLink buttons are programmed using
this procedure. You do not need to erase all
channels when programming additional but-
tons.
1. Place the ignition switch into the ON/RUN
position.
GETTING TO KNOW YOUR VEHICLE

NOTE:
For vehicle’s equipped with Keyless Enter-
N-Go, place the ignition in the RUN posi-
tion with the Engine ON. Make sure to
program HomeLink with the vehicle out-
side of the garage, or with the garage door
open at all times.
2. Place the garage door opener transmitter 1 to 3 inches (3 to 8 cm) away from the
HomeLink button you wish to program,
while keeping the HomeLink indicator
light in view.
3. Push and hold the HomeLink button you want to program while you push and hold
the garage door opener transmitter button
you are trying to replicate .
4. Continue to hold both buttons until the Instrument Cluster Display changes from
“CHANNEL # TRAINING” to “CHANNEL
# TRAINED.” Once this happens, release
both buttons. NOTE:
• It may take up to 30 seconds or longer in some cases for the channel to train.
• If “DID NOT TRAIN” appears in the instrument cluster display repeat from
Step 2.
NOTE:
Make sure the garage door opener motor is
plugged in before moving on to the rolling
code/non-rolling code final steps.
Rolling Code Garage Door Opener Final Steps
NOTE:
You have 30 seconds in which to initiate
rolling code final step 2, after completing
rolling code final step 1.
1. At the garage door opener motor (in the garage), locate the “LEARN” or “TRAIN”
button. This can usually be found where
the hanging antenna wire is attached to
the garage door opener motor. Firmly push
and release the “LEARN” or “TRAIN”
button. 2. Return to the vehicle and push the pro-
grammed HomeLink button three times
(holding the button for two seconds each
time). The instrument cluster display will
show “CHANNEL # TRANSMIT”. If the
garage door opener motor operates, pro-
gramming is complete.
3. Push the programmed HomeLink button to confirm that the garage door opener
motor operates. If the garage door opener
motor does not operate, repeat the final
steps for the rolling code procedure.
Non-Rolling Code Garage Door Opener Final
Steps
1. Push and hold the programmed HomeLink button and observe the instru-
ment cluster display. If the instrument
cluster display shows the “CHANNEL #
TRANSMIT,” programming is complete.
2. Push the programmed HomeLink button to confirm that the garage door opener
motor operates. If the garage door opener
motor does not operate, repeat the steps
from the beginning.

WARNING!
• Your motorized door or gate will openand close while you are programming
the universal transceiver. Do not pro-
gram the transceiver if people or pets are
in the path of the door or gate.
• Do not run your vehicle in a closed
garage or confined area while program-
ming the transceiver. Exhaust gas from
your vehicle contains Carbon Monoxide
(CO) which is odorless and colorless.
Carbon Monoxide is poisonous when in-
haled and can cause you and others to
be severely injured or killed.
Programming HomeLink To A
Miscellaneous Device
Refer to “Programming HomeLink To A Ga-
rage Door Opener” for the procedure on how
to program HomeLink to a miscellaneous
device, as it follows the same procedure. Be
sure to determine if the device has a rolling
code, or non-rolling code before beginning
the programming process. NOTE:
Canadian radio frequency laws require trans-
mitter signals to time-out (or quit) after sev-
eral seconds of transmission, which may not
be long enough for HomeLink to pick up the
signal during programming. Similar to this
Canadian law, some U.S. gate operators are
designed to time-out in the same manner.
The procedure may need to be preformed
multiple times to successfully pair the device
to your HomeLink buttons.
Reprogramming A Single
HomeLink Button
To reprogram a single HomeLink button that
has been previously trained, without erasing
all the channels, follow the procedure below.
Be sure to determine whether the new device
you want to program the HomeLink button to
has a Rolling Code, or Non-rolling Code.
1. Cycle the ignition to the ON/RUN
position. NOTE:
For vehicle’s equipped with Keyless
Enter-N-Go, place the ignition in the RUN
position with the Engine ON. Make sure to
program HomeLink with the vehicle out-
side of the garage, or with the garage door
open at all times.
2. Push and hold the desired HomeLink but- ton until the instrument cluster display
shows the “CHANNEL # TRAINING”
message. Do not release the button.
3. Without releasing the button, proceed with
Step 2 in “Programming HomeLink To A
Garage Door Opener” and follow all re-
maining steps.

• Rear of the center console storagecompartment.
When the vehicle is turned off, be sure to
unplug any equipment as to not drain the
battery of the vehicle. All accessories con-
nected to the outlet(s) should be removed or
turned off when the vehicle is not in use to
protect the battery against discharge.WARNING!
To avoid serious injury or death:
• Only devices designed for use in this type of outlet should be inserted into any
12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while
driving the vehicle.
• If this outlet is mishandled, it may cause
an electric shock and failure.
CAUTION!
•Many accessories that can be plugged in
draw power from the vehicle's battery, even
when not in use (i.e., cellular phones,
etc.). Eventually, if plugged in long
enough, the vehicle's battery will discharge
sufficiently to degrade battery life and/or
prevent the engine from starting.
• Accessories that draw higher power (i.e.,coolers, vacuum cleaners, lights, etc.),
will discharge the battery even more
quickly. Only use these intermittently
and with greater caution.
CAUTION!
• After the use of high power draw acces-sories, or long periods of the vehicle not
being started (with accessories still
plugged in), the vehicle must be driven a
sufficient length of time to allow the
generator to recharge the vehicle's bat-
tery.
Power Inverter — If Equipped
A 115 or 230 Volt (150 Watts Maximum)
outlet is located on the center stack of the
instrument panel, to the right of the radio.
This outlet can power cellular phones, elec-
tronics and other low power devices requiring
power up to 150 Watts. Certain high-end
video game consoles will exceed this power
limit, as will most power tools.
