Dual Automatic Climate Control
System

The vehicle may have this climate control system.
The heating, cooling and ventilation can be controlled
with it.

Automatic Operation

AUTO (Automatic): Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode and the fan speed. There might be a
delay of two to three minutes before the fan comes on
when the automatic operation is used in cold weather.
For the automatic system to function, the temperature
must be set between 61°F (16°C) and 89°F (31°C).

1. Adjust the temperature to a comfortable setting.

2. Press the AUTO button.

Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster.

If the system is set at the warmest temperature
setting, 90°F (32°C), hot air will be directed to the
floor, the fan will increase to the highest speed, and
the system will remain in manual mode at that
temperature. The system will not return to automatic
until the temperature setting is lowered.

If the system is set at the coldest temperature
setting, 60°F (15°C), cold interior air will be
recirculated through the air panel outlets, and the
fan will increase to the highest speed. The
system will not return to automatic until the
temperature is raised.
