Air Intake & Distribution System
Outside air enters the plenum via inlets at the base of the windscreen.
Fresh mode - Air is drawn in through the plenum and into the blower unit. From the blower unit air enters the A/C unit where it is cooled and dehumidified as it passes through the evaporator. It is then ‘reheated’ to the selected temperature as it passes through the heater matrix,.
Air flows from the cabin into the boot via air vent grilles and through apertures in the rear parcel shelf. The air is exhausted from the vehicle through extraction vent assemblies (incorporating one way flaps) in the lower part of the rear bumpers, concealed by the bumper trim.
Recirculation mode - The air in the passenger compartment is drawn into the A/C system via the recirculation air inlets on the blower unit.

The A/C unit is linked and sealed to the defrost / demisting and cabin air ducting assemblies. The A/C unit incorporates two actuator operated flaps which regulate airflow to the selected air flow mode and temperature blend.
The centre vent duct incorporates a baffle plate which balances the volume of airflow of the centre and end of dash vents.
