●Air conditioning-linked temperature regulation function (type A) (if
equipped):
By introducing air from the air conditioning system into the auxiliary box,
canned drinks etc. can be kept hot or cold. However, as the temperature
inside the auxiliary box will become the same as the temperature of the air
flowing from the air conditioning sy stem, extreme heating and cooling are
not possible. In high humidity condition, be careful of objects inside the aux-
iliary box, as condensation may form.
● Using the air conditioning-linked temperature regulation function (type A) (if
equipped):
Allow the air conditioning system to operate, and use or to
select either or . ( P. 518, 527)
