To activate Lane Keeping Assist via the steering wheel in a Mercedes-Benz vehicle (including AMG models), follow these steps:

1. Locate the Lane Keeping Assist Button

• The button to activate or adjust Lane Keeping Assist (or Lane Departure Warning) is typically located on the steering wheel itself or on the left stalk (indicator lever) of the steering column. In some models, it may be available on the dashboard or within the MBUX touchscreen menu.
• If the button is located on the steering wheel, it's usually found on the left side, along with other driving assistance functions.

2. Press the Lane Keeping Assist Button

• Press the button to activate the system. You should see an indicator light or a notification on the instrument cluster or the heads-up display showing that Lane Keeping Assist is now activated.
• In some cases, the button may need to be held for a few seconds to activate the system, especially if the system also has settings for adjustment, like warning sensitivity.

3. Check the Instrument Cluster or Display

• Once activated, check the instrument cluster or digital display for visual confirmation that the system is engaged. This may appear as a lane icon, with the steering wheel symbol or a message indicating that Lane Keeping Assist is active.
• The system might also display its status (e.g., whether it's actively helping to steer or simply providing warnings).

4. Adjust Settings (if necessary)

• In some Mercedes-Benz models, you can customize the behavior of Lane Keeping Assist, such as how aggressively it helps steer the car back into the lane if it detects you drifting.
• To access and adjust these settings, use the MBUX multimedia system or the steering wheel controls (such as the touchpad or buttons) to navigate to Driving Assistance settings in the vehicle's menu.

5. Keep Hands on the Steering Wheel

• For Lane Keeping Assist to function properly, you need to keep your hands on the steering wheel. This is because the system may provide steering inputs to gently correct your steering if it detects unintentional lane departure. If your hands are off the wheel, you might receive a warning.

6. Lane Departure Warning vs. Lane Keeping Assist

• Lane Departure Warning alerts you if the vehicle drifts out of its lane without signaling.
• Lane Keeping Assist provides additional intervention, such as steering adjustments to help guide the vehicle back into the lane.
• Depending on your vehicle model, these systems might be integrated, or you may need to activate them separately.

7. Deactivate Lane Keeping Assist

• To deactivate the system, simply press the Lane Keeping Assist button again or disable it through the MBUX menu. If the button is on the steering wheel, it should illuminate or show a message confirming that the system is now off.

Summary of Key Steps:

• Locate and press the Lane Keeping Assist button (usually on the steering wheel or stalk).
• Confirm activation via the instrument cluster or display.
• Adjust settings if necessary through the MBUX system.
• Ensure your hands remain on the wheel for the system to function correctly.

These instructions may vary slightly depending on the specific model and year of your Mercedes-Benz or AMG vehicle, so it’s a good idea to refer to the owner’s manual for the most accurate information.
