Dual Automatic Climate Control System With this system you can control the heating, cooling and ventilation for your vehicle. 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 you setthe system atthe 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 you set the system at the coldest temperature setting, 60°F (ISOC), 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. In cold weather, the system will start at reduced fan speeds to avoid blowing cold air into your vehicle until warmer air is available. The system will start out blowing air at the floor but may change modes automatically as the vehicle warms up to maintain the chosen temperature setting. Automatic Operation AUTO (Automatic): Press the AUTO button for automatic control of the inside temperature, the air delivery mode and the fan speed. You may notice a delay of two to three minutes before the fan comes on when the automatic operation is used in cold weather. 3-20
