Can a Mercedes-Benz be powered on without ignition?

[JaylaAnn]

Mercedes-Benz can be powered on without ignition. Methods to power on without ignition: When the engine is off, press and hold the start button for 3 seconds without stepping on the brake, or press the ignition button twice to turn it on. For key-type ignition, turn the key from the LOCK position to the ACC or ON position (ACC provides partial power, ON provides full power), as long as it is not turned to the START position. Precautions for powering on without ignition: Avoid prolonged use of the battery power and do not turn on high-power devices like headlights, as this may drain the battery and prevent normal engine startup, or even shorten the battery lifespan. When performing vehicle maintenance, always disconnect the power to prevent short circuits or accidental ignition.
