- When the function selector switch is in the FLOOR or MIX position, the auxiliary system will direct air to the floor.
- When the function selector switch is in the VENT position, the auxiliary system will direct air to the overhead vents.
- When the function selector switch is in the NORM A/C or MAX A/C position, air-conditioned air is distributed through the A/C registers.
- The auxiliary system uses only recirculated air from the vehicle interior. Outside air intake is not available.
