respectively. With the temperature setting in these posi-
tions, the system does not attempt automatic comfort
control.
Air Conditioning
The air conditioning in this system is automatic.
Pressing this button while in AUTO mode will
cause the LED to flash three times and remain off.
This indicates that the system is in AUTO and requesting
the air conditioning is not necessary.
Recirculation
The system will automatically control recircu-
lation. However, pressing this button will tem-
porarily put the system in “Recirculation”
mode. This can be used when outside condi-
tions such as smoke, odors, dust, or high humidity are
present. This will cause the LED to illuminate.
NOTE:
• The surface of the climate control panel, and the top
center of the instrument panel should be kept free of
debris due to the climate control sensor’s location.
Mud on the windshield may also cause poor operation
of this system.
• To provide you with maximum comfort in the auto-
matic mode, during cold start-ups the blower fan will
remain off until the engine warms up. However, the
fan will engage immediately if the defrost mode is
selected or if you manually select a blower speed.
• Under certain conditions (after the vehicle is turned
off) the climate control system may recalibrate and a
noise may be heard for 20 seconds. This is part of
normal operation.
