• With the heater version, only one positioning motor is installed for both left and right temperature doors. Both doors are connected to each other via a shaft.

• Beginning November 2007, a "heater" air distribution housing with a door in the air outlet to the defroster vents in the instrument panel without a side cut-out is gradually being installed.
