| Description and Operation The new heating and ventilation system ensures even air distribution. The temperature control and air distribution flaps are controlled by two operating cables. All vehicles have a recirculated air function, with the flap controlled by a servo motor. Air is supplied to the windscreen and side windows regardless of the air distribution setting. The clean air filter is fitted as standard in most countries. This cleans the incoming fresh air of pollen and dirt particles. It must be renewed after every 40,000 km under normal operation conditions, or after 20,000 km under difficult conditions. If no clean air filter is installed, a plastic grille is fitted over the air intake. This can easily be replaced with a clean air filter. Air distribution operating switch Face level The main flow of air enters the passenger compartment at face level. Face level/floor level The main flow of air enters the passenger compartment in equal parts at face level and floor level, and a small amount flows to the demister nozzles of the side windows. Floor level The main flow of air enters the passenger compartment at floor level, and a smaller amount flows to the demister nozzles of the side windows. Demist/floor level The main flow of air enters the passenger compartment in equal parts at the windscreen and at floor level, and a smaller amount flows to the demister nozzles of the side windows. Demist The main flow of air enters the passenger compartment at the windscreen and a smaller amount flows to the demister nozzles of the side windows. Air distribution operating switch Air distribution operating cables NOTE:The Bowden cables for LHD and RHD vehicles are identical. However, they are fastened to the air flap operating mechanism with the respective reverse side of their connectors. The air distribution switch operates with two Bowden cables. The cables operate the air distribution valves in the heater housing. To remove and install the cables, the rotary switch must be turned as far as it will go to the left. The air flap mechanism engages easily in this position, making the installation of the cables easier. |
