Heating and ventilation (Heating & ventilation)

HEATING AND VENTILATION

The heating and ventilation system controls the temperature and distribution of air supplied to the vehicle interior. Air is drawn into a heater assembly through a connector hose and an air inlet duct or, on vehicles with air conditioning, the cooling unit. See Air Conditioning, Description and Operation.

In the heater assembly, the air can be heated and supplied as required to fascia and floor level outlets. An electrical variable speed blower, and/or ram effect when the vehicle is in forward motion, forces the air

through the system. Temperature, distribution and blower controls are installed on a panel on the centre console.
