Climate Controls Dual Climate Control System With this system you can control the heating, cooling and ventilation for your vehicle. AUTO will appear on the display next to the fan, mode indicators, and recirculation indicator if your vehicle is equipped with the optional air quality sensor. 1. Press the AUTO button. 2. Adjust the temperature to a comfortable setting, generally, between 70°F (21°C) and 80°F (27°C). Choosing the coldest or warmest temperature setting will not cause the system to heat or cool any faster. If you set the system at the warmest temperature setting, the system will try to continuously heat the vehicle and will not adjust the system down as the vehicle warms up. In cold weather, the system may 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. The length of time needed for warm up will depend on the outside temperature and the length of time that has elapsed since your vehicle was last driven. 3. Wait for the system to regulate. This may take from 10 to 30 minutes. Then adjust the temperature, if necessary. Automatic Operation Vehicles With Heated and Ventilated Seats Shown, Vehicles Without Similar AUTO (Automatic): When this button is pressed and the temperature is set, the system will automatically control the inside temperature, the air delivery mode, the air conditioning compressor, and the fan speed. 3-48
