190 UNDERSTANDING YOUR INSTRUMENT PANEL A/C Recirculation Programming The recirculation control is programmed to cancel the recirculation mode when the ignition key is turned OFF and will reset to the outside air mode when the ignition key is turned "ON". The frequent use of outside air will help keep odors from building up within the air conditioner-heater housing. It is recommended that the recirculation mode be used as little as possible, especially in humid climates. For hot and dry climates, or people who are allergic to pollen and find frequent use of the recirculation mode necessary, the recirculation mode can be programmed to not automatically reset to the outside mode by using the following procedures: • Turn the ignition switch to the OFF position. • Press and hold the recirculation button. • While holding the recirculation button, turn the ignition switch to the "RUN" position. • Continue holding the recirculation button for 4 seconds, then release. The recirculation control is now programmed so that the recirculation mode will not reset to the outside air mode when the engine is restarted. The recirculation programming can be changed back by repeating this procedure.
