• Convenience: The system automatically restarts your engine, making it easier for you to drive without manual input.

Understanding the functionality and benefits of Stop/Start technology empowers you to make informed decisions while driving your Mercedes.

How the Feature Works

The Stop/Start feature in your Mercedes enhances fuel efficiency and reduces emissions by managing engine activity during stops. Understanding the processes of engine shutdown and restart can help you utilize this feature effectively.

Engine Shutdown Process

When your vehicle comes to a stop, the Stop/Start system automatically initiates the engine shutdown. This occurs when you bring the vehicle to a complete stop and press the brake pedal. Once you’re stationary, the system detects the stop conditions, including brake engagement and time elapsed. It then turns off the engine, conserving fuel and reducing emissions. You’ll notice the dashboard indicator lights up to confirm that the engine has shut down.

Engine Restart Process

The engine restarts automatically when you release the brake pedal. As soon as you lift your foot, the system activates and cranks the engine back on, allowing you to resume driving without delay. This process occurs quickly, ensuring a seamless experience. If you don’t want the engine to restart immediately, simply engage the accelerator pedal, and it will remain off until you release the brake again.

In some cases, the system may not restart if it detects certain conditions, like low battery levels or high engine temperatures, ensuring your vehicle operates optimally. Understanding these processes allows you to use the Stop/Start feature to your advantage while driving.

Steps to Turn Off the Feature

You can easily turn off the Stop/Start feature in your Mercedes. Follow these steps to manage the settings.

Accessing the Settings

3. Confirm the change: Check for any confirmation message on your display, indicating the setting has been updated.

1. Test drive your vehicle: Start driving and then come to a complete stop. Observe if the engine remains running.
2. Look for indicator lights: Ensure that the Stop/Start indicator on your dashboard isn’t illuminated, confirming the feature is off.
