Air Intake and Distribution

Air Distribution
Outside air enters the plenum via four inlets in the lower windshield panel.

If the air conditioning system is operating in FRESH mode (not recirculation mode), then air is drawn through the four plenum apertures (and particle filters where fitted) and into the air conditioning unit via the blower interconnecting ducts in the LH and RH blower assemblies. Air is cooled and dehumidified as it passes through the evaporator and is then 'reheated' to the required temperature as it passes through the heater matrix.

In RECIRCULATION mode, the air in the passenger compartment is drawn into the air conditioning unit via the recirculation air inlets on the blower assemblies.

In FRESH mode, air flows from the cabin into the trunk through a gap between the backlight and the parcel shelf. The air is exhausted from the vehicle through extraction vent assemblies (incorporating one way flaps) whose outlets are above the rear mufflers.

Air Particle Filter







The air particle filter system (where fitted) is located in the plenum below the windshield.


NOTE: Refer to 'Filter Compensation', Sensors and Controls


The filter elements are retained by adhesive strip which is attached to the filter moulding; the filter is fitted with the light, flocked surface towards the engine.
