Buick 2000 manual Heating, Defogging and Defrosting

Heating

If your vehicle has the electronic touch system, on cold days, use HTR with the TEMPERATURE lever toward WARM.

If your vehicle has the Dual Automatic Comfortemp system, and on cold days, if the AUTO 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 by selecting the extreme comfort setting. 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 AUTO mode and change the fan speed.

With each system, outside air will be brought in and sent through the floor outlets. The heater works best if you keep your windows closed while using it.

Defogging and Defrosting

If you have the electronic touch system, adjust

the TEMPERATURE lever toward WARM and the FAN lever toward HIGH.

If you have the Dual Automatic Comfortemp system, use the FRONT button to defog or defrost the windshield. By choosing this button, the airflow will be directed at the windshield. Adjust your comfort level by pressing the TEMP up or down arrow. The fan speed will be controlled by the system. You can change the fan speed by pressing the top of the FAN button to increase speed, and the bottom of the button to decrease speed.

To reduce the chance of fogging your windows in cold weather, using the electronic touch system, select HTR to supply air through the floor outlets. Then move the FAN lever to HIGH for a few moments before driving away. This will blow moist air from the intake outlets toward the floor, not the windshield. If you have the Dual Automatic Comfortemp system, the AUTO setting will do this for you. Manual operation of the automatic comfortemp system in the FLOOR mode will also supply air through the floor outlets.
