Driver's Side Temperature Button
The red and blue temperature buttons adjust the air
temperature coming through the system. Press the blue
button for a cooler setting or the red button for a
warmer setting.
Passenger's Side Temperature Knob
With this feature, the right front passenger can control
the temperature of air for his/her own zone. The
passenger can select a four degree warmer or cooler
temperature from the driver's setting.
To turn the system on, press the knob on the passenger's
side armrest. Turn the knob clockwise to increase the
temperature and counterclockwise to decrease the
temperature. Press the knob again to turn the system off.
Outside Temperature Display
The outside temperature is always displayed when your
vehicle is running. You can change it from Fahrenheit to
Celsius by pressing the ENG/MET (English/metric)
button on the Driver Information Center (DIC).The outside temperature sensor is located near the front
grille. The sensor can be affected by road or engine heat
during idling, slow driving or when the engine is first
started after a short trip. In order to ensure proper
automatic climate control operation, the outside air
temperature display may not update as quickly as
expected. This is to allow the air surrounding the outside
temperature sensor to be as close to the actual outside
conditions as possible. This is determined by how much
time has elapsed since the vehicle has been turned off and
by vehicle speed.
Mode Controls
The AUTO/ECON button automatically controls the
direction of air delivery for air conditioning and non
-air
conditioning modes.
Automatic Operation
When the system is set for automatic operation, sensors
will control the air delivery mode. Air will come from
the floor, middle or windshield outlets. The fan speed
will vary as the system maintains the selected
temperature setting.
Be careful not to put anything over the solar sensor
located in the middle of the instrument panel near the
windshield. This sensor is used by the automatic system
to regulate temperature.

To find your comfort zone, start with the 75
F (24
C)
setting and allow about 30 minutes for the system to
regulate. Press the red or blue temperature buttons to
adjust the temperature if necessary. If you choose 60
F
(16
C), the system will remain at that maximum cooling
setting and will not regulate fan speed. If you choose the
temperature of 90
F (32
C), the system will remain at
that maximum heating setting and will not regulate fan
speed. Choosing either maximum setting will not cause
the system to heat or cool any faster.
With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air. In cold weather, when the system senses the need
for heat, the airflow will be directed out the floor
outlets. As the interior temperature approaches a desired
setting, the blower speed will decrease. To maintain
interior comfort, the airflow may move to the instrument
panel air outlets and floor outlets (bi
-level mode). On
bright sunny days in cold weather, the airflow may come
out of the air conditioning outlets (AC mode) to
maintain comfort and prevent stuffiness.If your vehicle is sitting out on a hot day and you have it
set on AUTO, the air will first flow out the floor air
outlets for a few seconds. That is normal. This is to
expel hot air from the air outlets. As the air is cooled,
the airflow will move through the air conditioning
outlets. If you start your vehicle with the fan setting on
HI, it will skip the air conditioning purge.
To avoid blowing cold air in cold weather, the system will
delay turning on the fan until warm air is available. The
length of delay depends on the outside air temperature,
engine coolant temperature or the time since the engine
was last started. As the coolant warms up, the blower fan
speed will gradually increase and air will flow from the
heater outlets, with some airflow to the windshield to
prevent fogging under most normal conditions.
If you leave your vehicle, the system will remember the
control setting the next time you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation, whereas, DEFROST will change
to automatic operation when the ignition is shut off and
then turned back on.

If you leave your vehicle, the system will remember
the control setting the next time you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation, whereas, DEFROST will change
to automatic operation when the ignition is shut off and
then turned back on.
Manual Operation
You may manually adjust the air delivery mode or
fan speed.
AC: This setting directs airflow through the middle
instrument panel outlets.
BI-LEVEL: This setting directs air into your
vehicle in two ways. Cool air is directed to the upper
portion of your body through the four instrument panel
outlets while warmed air is directed to the floor.
HEATER/DEFROST: This setting directs air to
the floor outlets and toward the windshield.
HEATER: This setting directs warmed air
through the floor outlets. Some warm air is diverted to
the windshield to minimize fogging.
DEFROST: Press this button to quickly remove
fog or frost from the windshield. This setting sends most
of the airflow to the windshield with only a small
amount to the floor outlets.
FAN SPEEDS: Press the button with the fan
symbol on it until AUTO is displayed on the screen.
At this setting, the fan speed is automatically controlled.
If it is cold outside, the blower may not run in the
maximum high fan speed right away. The system
checks the temperature of the engine coolant to assure
it is warm enough to provide heat. When the engine
coolant is warm, the controller allows the fan to
gradually increase to a higher speed. This prevents
cold air from blowing into the passenger compartment.
If you want the blower fan at a high speed, press the up
arrow button until you see HI on the display. If you want
the fan speed to be automatic, but you like the fan speed
to be higher than the AUTO setting, press the fan
symbol button until HI AUTO is shown on the display.
If you want the blower fan at a low speed, press the
down arrow button until LO is shown on the display.
If you want the fan speed to run lower than the AUTO
setting, press the button until LO AUTO is shown on
the display.

3-10 Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
With the digital cluster climate control panel, press the
AUTO/ECON button to assist in cooling air and in
maintaining proper airflow. Adjust the temperature to a
comfortable setting by pressing the blue button to cool
your vehicle and pressing the red button to warm your
vehicle. Press the fan button arrows up or down to adjust
the fan speed.
If your vehicle has a console climate control panel
(which is standard with the analog cluster), press the AC
button or the TEMP/AUTO knob to turn the system on.
The system will cool and dehumidify the air inside the
vehicle. Also while in the AUTO mode, the system will
use recirculation as necessary to cool the air. You may
also need to adjust the interior temperature and the fan
speed as needed.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle's engine speed
and power. This is normal because the system is
designed to cycle the compressor on and off to
keep the desired temperature.
Heating
With the digital cluster climate control panel, press the
AUTO/ECON button to direct airflow and to help save
fuel. Adjust the temperature, if necessary, by pressing
the blue button to decrease temperature and pressing the
red button to increase temperature. Also remember to
adjust the fan speed by pressing the up or down arrow.
If your vehicle has a console climate control panel
(which is standard with the analog cluster), press the
MODE button to select heater. Adjust the interior
temperature to a comfortable level and if the fan speed
needs adjusting, press the up or down arrow.
With each system, outside air will be brought in and sent
through the floor, air conditioning or bi
-level outlets
(depending on the condition). The heater works best if
you keep your windows closed while using it.
Defogging and Defrosting
On cool, humid days, use defog (digital cluster climate
control panel only) to keep the windshield and side
windows clear. Use defrost to remove fog or ice from
the windshield quickly in extremely humid or
cold conditions.

Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.

Keep the air path under the front seats clear
of objects. This helps circulate air throughout
your vehicle.
HVAC Steering Wheel Controls
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls operate some
audio controls. See ªAudio
Steering Wheel Controlsº
in the Index.
FAN SPEED: Press the up arrow lever to
increase the fan speed and the down arrow lever to
decrease fan speed.
TEMP: Press the up arrow lever to increase
the temperature and the down arrow lever to
decrease temperature.
Climate Control Personalization
(If Equipped)
With this feature, your vehicle will recall the latest
climate control settings as adjusted the last time your
vehicle was operated. This feature allows two different
drivers to store and recall their own climate control
settings. The settings recalled by the climate control
system are determined by which remote keyless entry
transmitter (ª1º or ª2º) was used to enter the vehicle.
The number on the back of the remote keyless entry
transmitter corresponds to driver 1 or to driver 2. After
the unlock button is pressed on the remote keyless entry
transmitter or the ignition key is placed in the ignition
(the ignition must be turned to LOCK), the climate
control settings will automatically adjust to where they
were last set. The settings can also be changed by briefly
pressing the memory seat buttons 1 or 2 located on the
driver's door.
