7. Front Defrost ModeAir is directed through the windshield and side
window demist outlets. Use Defrost mode with
maximum blower and temperature settings for best
windshield and side window defrosting.
NOTE: The air conditioning compressor may operate in
Mix and Defrost, or a blend of these modes even if the
A/C button is not pressed. This dehumidifies the air to
help dry the windshield. To improve fuel economy, use
these modes only when necessary.
8. Electronic Rear Window Defrost Press this button to turn on the rear window
defroster and the heated outside mirrors (if
equipped). An indicator in the button will illuminate
when the rear window defroster is on. The rear window
defroster automatically turns off after approximately
10 minutes. For an additional five minutes of operation,
press the button a second time. NOTE:
•You can turn off the heated mirror feature at anytime
by pressing the rear window defroster switch a second
time.
•To prevent excessive battery drain, use the rear win-
dow defroster only when the engine is operating.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to
the heating elements. Labels can be peeled off
after soaking with warm water.

9. Recirculation Control Button Press this button to choose between outside air
intake or recirculation of the air inside the
vehicle. A lamp will illuminate when you are in
Recirculation mode. Only use the Recirculation
mode to temporarily 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:
•If the Recirculation button is pressed when the system
is in Defrost mode the Recirculation LED indicator will
flash 3 times to indicate Recirculation mode is not
allowed.
•In Floor and Mix mode the system will turn off
Recirculation mode after five minutes of operation.
You can select Recirculation mode again if desired.
•Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
•In cold or damp weather, the use of the Recirculation
mode will cause windows to fog on the inside because
of moisture buildup inside the vehicle. For maximum
defogging, select the outside air position.

The rear blower control, located in the rear overhead
console, has an off position and a range of blower speeds.
This allows the second row seat occupants to control the
volume of air circulated in the rear of the vehicle.CAUTION!
Interior air enters the Rear Manual Climate Control
system through an intake grille, located in the right
side trim panel behind the third row seats. The
heater outlets are located in the right side trim panel,
just behind the sliding door. Do not block or place
objects directly in front of the inlet grille or heater
outlets. The electrical system could overload, causing
damage to the blower motor.
Rear Temperature Control
The rear mode selection REAR,allows the settings to be
controlled by the rear mode control knob.
To change the temperature in the rear of the vehicle,
rotate the temperature control knob counterclockwise for
cold air, and clockwise for heated air.

Headliner ModeAir comes from the outlets in the headliner. Each of
these outlets can be individually adjusted to direct
the flow of air. Moving the air vanes of the outlets to one
side will shut off the airflow.
Bi-Level Mode Air comes from both the headliner outlets and the
floor outlets.
NOTE: In many temperature positions, the Bi-Level
mode is designed to provide cooler air out of the head-
liner outlets and warmer air from the floor outlets.
Floor Mode Air comes from the floor outlets.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
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended, because it
may cause window fogging.
