UNDERSTANDING YOUR INSTRUMENT PANEL 313 • Extended use of recirculation may cause the windows to fog. If the interior of the windows begins to fog, push the Recirculation button to return to outside air. Some temp/humidity conditions will cause captured interior air to condense on windows and hamper visibility. For this reason, the system will not allow Recirculation to be selected while in defrost mode. Attempting to use the recirculation while in these modes will cause the LED in the control button to blink and then turn off. • Most of the time, when in Automatic Operation, you can temporarily put the system into Recirculation Mode by pushing the Recirculation button. However, under certain conditions, while in Automatic Mode, the system is blowing air out the defrost vents. When these conditions are present, and the Recirculation button is pushed, the indicator will flash and then turn off. This tells you that you are unable to go into Recirculation Mode at this time. If you would like the system to go into Recirculation Mode, you must first move the Mode knob to Panel, Bi-Level, Mix, or Floor and then push the Recirculation button. This feature reduces the possibility of window fogging. Operating Tips NOTE: Refer to the chart at the end of this section for suggested control settings for various weather conditions. Summer Operation The engine cooling system must be protected with a high-quality antifreeze coolant to provide proper corrosion protection and to protect against engine overheating. A solution of 50% OAT (Organic Additive Technology) coolant that meets the requirements of Chrysler Material Standard MS.90032 and 50% water is recommended. Refer to "Maintenance Procedures" in "Maintaining Your Vehicle" for proper coolant selection. 4
