The air distribution system consists of:

• climate control system:
  • blower fan
  • damper
  • filter
  • recirculation throttle.
• air ducts
• vents.

Dampers control the outgoing air to:

• defroster
• the dashboard vents
• the floor outlets
• the B post vents.

Fresh air enters the climate control system through the fresh air intake under the plenum chamber.

The fresh air intake is located:

• on the right-hand side of the left-hand drive vehicle
• on the left-hand side of the right-hand drive vehicle.

Air enters the climate control system and is distributed by a large number of air vents to the passenger compartment. After circulating, the air leaves the passenger compartment via the evacuation valves in the cargo compartment.
