In the context of vehicles, particularly those equipped with modern fuel-saving technologies, the term "self-start" is more accurately referred to as a "start-stop system" or "stop-start technology." This system automatically shuts down and restarts the internal combustion engine to reduce fuel consumption and emissions, especially when the vehicle is idling. For example, in manual transmission vehicles, the engine shuts down when the car is stopped, shifted into neutral, and the clutch is released. The engine restarts when the clutch is pressed to select a gear. In automatic transmission vehicles, the engine shuts down when the car comes to a full stop and the foot brake pedal is pressed. This technology is widely used in various models from manufacturers like Renault, Subaru, and Suzuki, and it can reduce fuel consumption by 3-10% depending on driving conditions.
