In this intake mode, the air from inside the passenger compartment
will be sucked by the blower and utilized further to ventilate/cool/
heat the cabin.
For quick cabin cooling/heating or while driving through dusty/
polluted region, re-circulation mode can be selected for short
periods. Driving with this mode active may lead to better fuel
economy and longer HVAC filter life.
However, running the air conditioner in re-circulation mode for long
will make cabin air too dry and oxygen level drops inside cabin
turning the air stale. On the contrary, keeping air intake control in
recirculation mode for long, with air conditioner switched OFF, will
make cabin air too humid and are more likely to become foggy.
Hence never drive in recirculation mode for long, shift back to fresh
air mode as soon as possible.
Never keep recirculation mode selected continuously for long.
Prolonged use of the HVAC system in recirculation mode may
cause windshield/windows to mist/fog-up, impairing visibility
which can lead to an accident, endangering you and others.
