On sunny days, when the air is moderately warm or cool, use Bi-Level to deliver warm air to the floor ducts and cooler air to the instrument panel outlets. On days like these, the sun may adequately warm your upper body, but your lower body may not be warm enough. To warm or cool the air delivered, adjust the TEMPERATURE lever. The amount of fresh air entering the vehicle is limited when Recirculation is selected. This is helpful when you are trying to cool the air in your vehicle or limit the air entering the vehicle. If your vehicle has the Dual Automatic ComforTempt system and it is set for Automatic Operation, on very hot days, the system will automatically enter recirculation mode and the temperature door will be positioned at the full cold position for maximum cooling. If the system is not in the automatic mode, recirculation should be selected to provide maximum cooling. You can choose the extreme comfort setting of 60_F (16_C), but the system will not cool any faster as a result. Heating If your vehicle has the electronic touch system, on cold days, use HTR with the TEMPERATURE lever toward WARM and the fan speed toward HIGH. If your vehicle has the Dual Automatic ComforTemp system, and on cold days, if the automatic mode is selected, the system will automatically direct the air toward the floor and the temperature door will be positioned at the full hot position. You can choose the extreme comfort setting of 90_F (32_C) but the system will not warm up any faster as a result. If the outside temperature is cold, the fan will be delayed to avoid blowing cold air. Pushing the FAN, AIR FLOW or FRONT buttons will override this delay, turn off the automatic mode and return the system to manual operation. With each system, outside air will be brought in and sent through the floor ducts. The heater works best if you keep your windows closed while using it. 3-9
