If you ever wish to interrupt the system while it lists
options, press the Voice Command
button, listen
for the beep, and say your command.
Pressing the Voice Command
button while the
system is speaking is known as “barging in.” The system
will be interrupted, and after the beep, you can add or
change commands. This will become helpful once you
start to learn the options.
NOTE: At any time, you can say the words “Cancel”,
“Help” or “Main Menu”.
These commands are universal and can be used from any
menu. All other commands can be used depending upon
the active application.
When using this system, you should speak clearly and at
a normal speaking volume. The system will best recognize your speech if the win-
dows are closed, and the heater/air conditioning fan is
set to low.
At any point, if the system does not recognize one of your
commands, you will be prompted to repeat it.
To hear the first available Menu, press the Voice Com-
mand
button and say “Help” or “Main Menu”.
Commands
The Voice Command system understands two types of
commands. Universal commands are available at all
times. Local commands are available if the supported
radio mode is active.
Changing the Volume
1. Start a dialogue by pressing the Voice Command
button.
2. Say a command (e.g., “Help”).

CLIMATE CONTROLS
Automatic Temperature Control (ATC)
The Automatic Temperature Control system automati-
cally maintains the climate in the cabin of the vehicle at
the comfort levels desired by the driver and passenger.
Automatic Operation
Operation of the system is quite simple.
1. Turn the Mode Control knob (on the right) and the
Blower Control knob (on the left) to AUTO.
NOTE:The AUTO position performs best for front seat
occupants only.
2.
Dial in the temperature you would
like the system to maintain by rotating
the Temperature Control knob. Once the
comfort level is selected, the system will
maintain that level automatically using
the heating system. Should the desired
comfort level require air conditioning,
the system will automatically make the adjustment.
You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the “O” (OFF) position on the blower control stops the
system completely and closes the outside air intake.
Automatic Temperature Control
242 UNDERSTANDING YOUR INSTRUMENT PANEL

The recommended setting for maximum comfort for the
average person is 72°F (22°C); however, this may vary.
NOTE:
•The temperature setting can be adjusted at anytime
without affecting automatic operation.
•Pressing the Air Conditioning Control button while in
AUTO mode will cause the LED in the control button
to flash three times and then turn off. This indicates
that the system is in AUTO mode and requesting the
air conditioning is not necessary.
•If your air conditioning performance seems lower than
expected, check the front of the A/C condenser located
in front of the radiator for an accumulation of dirt or
insects. Clean with a gentle water spray from behind
the radiator and through the condenser. Fabric front
fascia protectors may reduce airflow to the condenser,
reducing air conditioning performance.
Blower Control
For full automatic operation or for
automatic blower operation, turn the
knob to the AUTO position. In manual
mode there are seven blower speeds
that can be individual selected. In off
position the blower will shut off.
Manual Operation
This system offers a full complement of manual override
features, which consist of Blower Preferred Automatic,
Mode Preferred Automatic, or Blower and Mode Pre-
ferred Automatic. This means the operator can override
the blower, the mode, or both. There is a manual blower
range for times when the AUTO setting is not desired.
The blower can be set to any fixed blower speed by
rotating the Blower Control knob (on the left).
NOTE:Please read the Automatic Temperature Control
Operation Chart that follows for details.

•Air Conditioner ControlPress this button to turn on the air
conditioning during manual operation
only. When the air conditioning is
turned on, cool dehumidified air will
flow through the outlets selected with
the Mode control dial. Press this but-
ton a second time to turn OFF the air
conditioning. An LED in the button illuminates when
manual compressor operation is selected.
•Recirculation Control The system will automatically control recircu-
lation. However, pressing the Recirculation
Control button will put the system in recircu-
lation mode. This can be used when outside
conditions such as smoke, odors, dust, or high humidity
are present. Activating recirculation will cause the LED in
the control button to illuminate. NOTE:
•When the ignition switch is turned to the LOCK
position, the recirculation feature will be cancelled.
•In cold weather, use of the Recirculation mode may
lead to excessive window fogging. The Recirculation
mode is not allowed in the floor, defrost, or defrost/
floor mode in order to improve window clearing.
Recirculation will be disabled automatically if these
modes are selected.
•Extended use of recirculation may cause the windows
to fog. If the interior of the windows begins to fog,
press the Recirculation button to return to outside air.
Some temp/humidity conditions will cause captured
interior air to condense on windows and hamper
visibility. For this reason, the system will not allow
Recirculation to be selected while in floor, defrost, or
defrost/floor mode. Attempting to use the recircula-
tion while in these modes will cause the LED in the
control button to blink and then turn off.

•Most of the time, when in Automatic Operation, you
can temporarily put the system into Recirculation
Mode by pressing the Recirculation button. However,
under certain conditions, while in Automatic Mode,
the system is blowing air out the defrost vents. When
these conditions are present, and the Recirculation
button is pressed, the indicator will flash and then turn
off. This tells you that you are unable to go into
Recirculation Mode at this time. If you would like the
system to go into Recirculation Mode, you must first
move the Mode knob to Panel, Panel/Floor and then
press the Recirculation button. This feature reduces the
possibility of window fogging.
Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
Use of the air Recirculation Mode during winter months is
not recommended because it may cause window fogging.
Vacation Storage
Anytime 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 the
fresh air and high blower settings. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an authorized dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a performance
test. Drive belt tension should also be checked at this
time.
CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condi-
tioning components. Such damage is not covered by
the New Vehicle Limited Warranty.
WARNING!
•Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer to
Warranty Information Book, located on the DVD,
for further warranty information.
•The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced technician.

Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by authorized dealers or other
service facilities using recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C system
sealers, stop leak products, seal conditioners, compressor
oil, and refrigerants.
A/C Air Filter
The filter is located in the fresh air inlet under the hood,
behind a removable panel in the cowl on the passenger
side of the vehicle, next to the windshield wipers. When
installing a new filter, ensure its proper orientation. 1. Remove the access door in the cowl screen by pressing
the retaining clips.

humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot coolant to
enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
•Do not overfill the coolant recovery bottle.
•Check the coolant freeze point in the radiator and in
the coolant recovery bottle. If antifreeze needs to be
added, the contents of the coolant recovery bottle must
also be protected against freezing.
•If frequent coolant additions are required, or if the
level in the coolant recovery bottle does not drop when
the engine cools, the cooling system should be pres-
sure tested for leaks.
•Maintain coolant concentration at 50% HOAT engine
coolant (minimum) and distilled water for proper
corrosion protection of your engine, which contains
aluminum components.
•Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory coolant performance, poor gas
mileage, and increased emissions.
