What are the steps to turn on the heating in an older Passat model?

[MacMatthew]

The steps to turn on the heating in an older Passat model are: start the car, turn on the air conditioning, switch to heating mode, and adjust the air vents once the air starts flowing. The heating system relies on the heat generated by the engine after it starts working. A small fan in the engine compartment blows the heat collected from the engine's cooling system into the car. The exterior changes in the older Passat model are mainly reflected in minor details, such as the omission of chrome trim on the side windows and around the body, the use of regular glass throughout the car, unpainted door handles, and smaller wheel sizes. In terms of interior features, leather seats remain standard, the front seats are manually adjustable, and the central armrest in the rear seats is omitted.
