As the interior of the vehicle warms up to your comfort set temperature, the fan speed will decrease and the temperature output may become cooler. If the interior temperature continues to warm up due to heating from the sun or outside temperature increases, the system may switch to other air delivery modes (typically DEFOG or BI-LEVEL). A Typical Hot Weather Example: The vehicle has been parked outside all day in hot weather above 80_F (27_C) and you have set the driver temperature at 73_F (23_C) and have selected the AUTO mode. The system will automatically adjust the temperature output to maximum cooling. The fan will start at a low speed momentarily to push the hot air to the floor of the vehicle and then go to a higher fan speed with cold airflow out of the instrument panel outlets. A small amount of airflow will continue through the lower ducts to cool the floor area. The air intake may start in the recirculated mode for maximum cooling performance. As the interior of the vehicle cools down to your comfort set temperature, the fan speed will decrease and the temperature output may become warmer. The air intake may shift from recirculation to outside air mode. If the interior continues to cool due to a decrease in the amount of heat the vehicle is absorbing from the sun or a decrease in the outside temperature, the system could switch to other air delivery modes (typically BI-LEVEL or DEFOG). Manual Settings With the automatic electronic dual climate control system, there are several manual settings you can use to control the system and override the AUTO operation. You can program the fan speed, air delivery mode, air intake mode and control the air conditioning operation using these settings. The system will still determine the temperature output level based on the driver-set temperature and the passenger temperature offset. 3-6
