Downloaded from www.Manualslib.com manuals search engine 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 hisher 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. Rotate the knob to the right to increase
the temperature and turn to the left 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 (EnglisWmetric)
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 AUTOECON 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.

the temperature and press the down arrow to decrease
the climate setting. Pressing the
OW button will turn
off the dual-zone function.

Press this button to deliver air through the floor, middle
or windshield outlets. The system will stay in the
selected mode until the
MODE button is pushed again.
Press the up or down arrow to cycle through the
available 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. Turn the TEMP/AUTO knob to adjust the
temperature
if necessary. If you choose 60 "F (1 6 " 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.

Downloaded from www.Manualslib.com manuals search engine OFF: Press this button to turn the system off. Fresh
air will continue to flow through the vehicle, and the
system will try
to maintain the previously set
temperature. The outside temperature will show on
the display when the system is
OFF.
AC: Press this button to turn the air conditioning on and
off. The system will cool and dehumidify the air inside
the vehicle. In the
AUTO mode, the display will show
that
AC is active, but the air conditioning compressor
only operates when the system determines it is needed.
0 RECIRCULATION: Press this button to limit the
amount of fresh air entering your vehicle. This is helpful
when you are trying to cool the air quickly or limit odors
entering your vehicle. In the
AUTO mode, the system
will use recirculation as necessary to cool the air.
Pressing the recirculation button will change the
operation to a manual mode and the air will recirculate
non-stop. Press this button again to turn off the
recirculation feature.
If you notice the windows fogging, press the recirculation button to exit the recirculation mode.
Electronic Solar Sensor
The sensor monitors the sun's solar radiation and is
located on top of the instrument panel near the
windshield. The
ECC panel uses this information to
automatically make the necessary temperature and
airflow adjustments to maintain your comfort.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band
is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one
of the identical size
and rating.
If you ever have a problem on the road and don’t
have a spare fuse, you can “borrow” one that has the same amperage. Pick some feature
of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
There are two fuse blocks in your vehicle: the engine
compartment fuse block and the rear compartment
fuse block.
