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 igni-
tion switch to the “RUN” position.
Continue holding the recirculation button for 4 sec-
onds, 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 program-
ming can be changed back by repeating this procedure.
