Recirculation mode to be selected while in the defrost or
defrost/floor modes. Attempting to use Recirculation
while in these modes will cause the LED in the button to
blink and then turn off.
Rear Climate Control — If Equipped
The Manual Rear Climate Control system has one floor
air outlet (passenger side), and two panel outlets in the
rear quarter trim (on each side). The unit provides warm
or cool air through the floor and upper outlets.
If rear heating/cooling is desired, press the Rear On/Off
Switch (located in the upper switch bank above the
controls) and select Floor, Bi-Level, or Panel from the
Rear Control Panel (right knob located on the right rear
quarter trim panel).The rear temperature, blower speed, and mode control
can be adjusted as desired by the third row seat occu-
pants.

NOTE:The rear climate control system cannot be con-
trolled from the front seat; it can only be turned on and
off. All control of the rear system must be performed by
the rear occupants.
Rear Blower Control
The left knob on the Rear Control Panel has four posi-
tions, “Off”, and a range of three blower speeds. This
allows the third row seat occupants to control the volume
of air circulated in the rear of the vehicle.
CAUTION!
Interior air enters the Manual Rear Zone Climate
Control system through an intake grille located in the
passenger side trim panel behind the third seat. The
heater outlets are located in the passenger 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 center knob on the Rear Control Panel allows the
third row seat occupants to have control of the rear
temperature as follows:
•When the temperature knob is in the cold (Blue)
position, cold air will be delivered from the outlets. As
the temperature knob is turned towards the hot (Red)
position, the air will get warmer.
Rear Mode Control
FloorAir flows through the floor outlet located on the
right side of the rear floor into the rear seating area.
Bi-Level Air flows through both the outlets located in the
rear quarter trim panels, and the one located on the
floor. The rear quarter trim panel outlets can be closed to
block airflow. Panel
Air flows through the outlets located in the rear
quarter trim panels. These registers can be closed to
block airflow.
Operating Tips
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it’s rainy or humid. In most cases,
turning on the air conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction and blower speed to maintain comfort.
As the temperature gets colder, it may be necessary to
direct air onto the windshield. Adjust the temperature
control and blower speed to maintain comfort. Higher
blower speeds will reduce fogging. Interior fogging on
the windshield can be quickly removed by selecting the
defrost mode.4

Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant, during summer, to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50%
concentration is recommended. Refer to Fluids, Lubri-
cants, and Genuine Parts in Section 7 for the proper
coolant type.
When using the air conditioner in extremely heavy
traffic, in hot weather, especially when towing a trailer,
additional engine cooling may be required. If this situa-
tion is encountered, operate the transmission in a lower
gear to increase engine RPM, coolant flow and fan speed.
When stopped in heavy traffic, it may be necessary toshift into NEUTRAL and press the accelerator slightly for
fast idle operation to increase coolant flow and fan speed.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other
obstructions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will ensure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
