Method to turn on the heater in a Mercedes-Benz C260: You need to increase the temperature setting of the air conditioning and then select an appropriate fan speed. It's important to note that if you want the air conditioning to produce heat, do not press the AC button, as the AC button is the cooling switch for the car's air conditioning. The car's heating system relies on the heat generated by the engine, which blows the heat collected by the cooling system into the cabin to create warm air. There are various types of car heating systems, categorized by heat source into hot water heating systems, gas heating systems, and exhaust heating systems, among others. Currently, small cars mainly use hot water heating systems, while large vehicles primarily use gas heating systems. The Mercedes-Benz C260 is a model introduced by Mercedes-Benz, with body dimensions of 4591mm in length, 1770mm in width, and 1444mm in height, and a wheelbase of 2760mm.
