5. Store the disc in its case after playing.
6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures may become
too high.
CLIMATE CONTROLS
The Air Conditioning and Heating System is designed to
make you comfortable in all types of weather.
Manual Air Conditioning and Heating System
The Manual Temperature Controls consist of a series of
outer rotary dials and inner push buttons.
260 INSTRUMENT PANEL AND CONTROLS

Blower Control
Use this control to regulate the
amount of air forced through the ven-
tilation system in any mode. The
blower speed increases as you move
the control to the right from the ªOº
(Off) position. There are four blower
speeds.
Temperature Control
Use this control to regulate the tem-
perature of the air inside the passenger
compartment. The blue area of the
scale indicates cooler temperatures
while the red area indicates warmer
temperatures.NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser: located in front of the radiator, for an accumula-
tion 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.
Mode Control (Air Direction)
Use this control to choose from several
patterns of air distribution. You can
select either a primary mode as iden-
tified by the symbols on the control, or
a blend of two of these modes. The
closer the setting is to a particular
symbol, the more air distribution you
receive from that mode.

NOTE:The air conditioning compressor operates in Mix
and Defrost, or a blend of these modes, even if the Air
Conditioning Snowflake button is not pressed. This de-
humidifies the air to help dry the windshield. To improve
fuel economy, use these modes only when necessary.
²Recirculation Control
Use this button to block the flow of outside
air from coming into the passenger compart-
ment. A light will illuminate when the sys-
tem is in recirculation mode. Only use the
recirculation mode as a temporary means to block out
any outside odors, smoke, or dust, and to cool the
interior rapidly upon initial start up in very hot or
humid weather.
NOTE:
²Continuous use of the recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
²The use of the recirculation mode in cold or damp
weather will cause windows to fog on the inside,
because of moisture build-up inside the vehicle. Select
the Outside Air position for maximum defogging.
²The A/C will engage automatically to prevent fogging
when the recirculation button is pressed and the mode
control is set to panel or panel / floor.
²The A/C can be deselected manually without disturb-
ing the mode control selection.
Air Conditioning Control
Use this button to engage the Air Conditioning. A
light will illuminate when the Air Conditioning
System is engaged
NOTE:The air conditioning compressor will not engage
until the engine has been running for about 10 seconds.

cabin infrared sensor mounted between the sun-visors
and from various sensors located throughout the vehicle.
The controls on the climate control provide the system
with operator input. Other sensors take account of ve-
hicle speed, A/C pressure, outside temperature, and
engine cooling temperature. Using all of these inputs, the
system automatically adjusts airflow temperature, air-
flow distribution, airflow volume, and the amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.
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 main-
tain 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 ªOº (Off) position on the blower control stops the
system completely and closes the outside air intake.
72ÉF (22ÉC) is the recommended setting for maximum
comfort for the average person; however, this may vary.

NOTE:
²The temperature setting can be adjusted at any time
without affecting automatic operation.
²Pressing 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.
²If your air conditioning performance seems lower than
expected, check the front of the A/C condenser: lo-
cated 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.
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.

²Air Conditioner Control
Press 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 button a second time to
turn off the air conditioning. An LED in the button
illuminates when manual compressor operation is
selected.
²Recirculation Control
The system will automatically control recir-
culation. However, pressing the Recircula-
tion Control button will temporarily put the
system in recirculation mode (ten minutes).
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. After ten minutes, the
system will return to normal AUTO mode function
and the LED will turn off.NOTE:
²When the ignition switch is turned to the LOCK
position, the recirculation feature will be cancelled.
²In 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.
²Extended 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.

þUse speed control in flat terrain and with light loads to
maximize fuel efficiency.
Towing Tips Ð Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
þCity Driving
When stopped for short periods of time, put transmission
in neutral and increase engine idle speed.
þHighway Driving
Reduce speed.
þAir Conditioning
Turn off temporarily.
þRefer to ªCooling Systemº under ªMaintenance Pro-
ceduresº in Section 7 of this manual for more informa-
tion.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Towing ± 2WD Models
Recreational towing is not allowed.
CAUTION!
Towing with the rear wheels on the ground can result
in severe transmission damage.
Towing Ð 4WD Models
The transfer case must be shifted into Neutral (N) for
recreational towing. The Neutral (N) selection button is
located at the top of the 4WD Control Switch. Shifts into
and out of transfer case Neutral (N) can take place with
the selector switch in any mode position.
