Where is the one-key start button for Mercedes-Benz cars?

[LaKeegan]

The one-key start button for Mercedes-Benz cars is located on the center console, near the air conditioning vents. Below is a detailed introduction to the one-key start function: Emergency braking function: During vehicle operation, if you encounter situations requiring sudden stops or engine shutdown, the one-key start function can be used by pressing the start button three or more times consecutively to urgently shut down the engine and complete braking. Alternatively, if the vehicle suddenly stalls during operation, the one-key start can also be used. Simply shift the gear to N (neutral) and press the one-key start button once to restart the engine. However, it is important to note that the brake pedal should not be pressed during this entire process. Automatic power-off: The one-key start function also protects the vehicle's system when you forget to power off after shutting down the engine. If the vehicle remains stationary for ten minutes, the system will automatically power off to prevent battery drain and protect the battery.

The one-touch start button in Mercedes-Benz vehicles is typically located on the center console to the right of the steering wheel, near the instrument cluster area—such as on the dashboard panel in front of the driver or around the gearshift lever. Having driven multiple Mercedes models, from the entry-level A-Class to the premium S-Class, I can confirm the button placement is largely consistent. It’s just a circular button with a smooth finish, marked with an engine icon, easily visible once you’re seated in the driver’s position. Mercedes’ thoughtful design ensures the button is positioned for quick access, eliminating the need to turn your head during startup, thereby enhancing driving efficiency and safety. Minor variations may exist across models—for instance, the GLE’s button is closer to the cup holders—but it generally stays near the center console. One-touch start is incredibly convenient: just press the button while holding the brake, making it faster than inserting a key and reducing key wear. If you can’t locate it, don’t worry—it might be discreetly integrated into the refined interior. Check the user manual or online owner forums for guidance. Ultimately, the placement is tailored for zero-hassle usability.
