Heated Seat Fan Control Defrost Rear Window Defogger Air Delivery Mode Control AUTO (Automatic): The system automatically controls the fan speed, air delivery, air conditioning and recirculation modes in order to heat or cool the vehicle to the desired temperature. To place the system in automatic mode: 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 the system is set 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. To avoid blowing cold air in cold weather, the system delays turning on the fan until warm air is available. The system starts out blowing air at the floor, but can automatically change modes as the vehicle warms up to maintain the chosen temperature setting. The length of time needed for warm up depends on the outside temperature and the length of time that has elapsed since the 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. The display can be changed from English to metric units through the Driver Information Center (DIC). See DIC Operation and Displays on page 3-72.
