4-Zone
In addition to the front A/C system, an A/C system for the
rear passenger area is available as an optional extra on all
Cayenne models. This second A/C system operates inde-
pendently of the front system. Here again, temperature,
air volume (blower) and left / right air distribution (zones)
are individually selectable. In conjunction with the
automatic front 2-zone A/C system therefore, the interior
climate can be controlled for a total of 4 individual zones.
The settings for the 4 zones can be made on the front
control panel. There is also a button on the front control
panel for the two rear zones. The settings for the rear
areas can be made after this button is pressed briefly. The
rear zones can also be controlled from the rear seats on
the rear control panel.
