Start-Stop Button: Hidden Features Most Drivers Don't Know

The Start-Stop button in modern cars offers more functions than simply starting and stopping the engine. In addition to the convenience of avoiding the traditional ignition key, the button can be used to lock the steering wheel, increasing security, and to activate the infotainment system without starting the engine. This latter function is particularly useful in low temperatures or after prolonged inactivity, allowing the fuel pump to warm up before starting. Manufacturers are constantly enhancing the security of these systems, despite the theoretical risk of signal interception.
