Service Connections
Cayenne model service connections are in front in the
engine compartment on the left side.
Air Distribution System
The air distribution system controls air volume,
temperature and direction within the passenger compart-
ment. The system can add or remove heat from the cabin
air and provide ventilation, heating, cooling and defrost
functions.
On Cayenne models, the air distribution housing contains
the evaporator, a heater core containing hot engine
coolant, blower fan, air control flaps and their actuators,
and passages to various outlets in the vehicle.
Air Ducting
With the manual and 2-Zone climate control system, the
temperature and air volume for the driver and front
passenger can be separately adjusted. Outlets are located
in the instrument panel, the rear console, and floor vents
under the front seats.
Air Ducting, 4-Zone
The optional 4-Zone automatic climate control system
adds a rear heating/cooling unit. The rear heating/cooling
unit includes a rear blower, heater core and evaporator,
along with the hoses, ducts and necessary controls.
When the vehicle is equipped with the 4-Zone system, air
from the front air distribution housing feeds the front seat
panel and side vents. Rear seat passengers receive
airflow only from the rear heating/cooling unit. The rear
unit supplies air to the vents in the rear console, B-pillar
and floor vents under the front seats. The rear
heating/cooling unit is located on the left side in the side
wall behind the left rear wheel.
