To use the AMG steering wheel for brake hold functionality, you'll typically be interacting with the vehicle’s brake assist system through the infotainment system, gear shift lever, or specific buttons. However, the AMG steering wheel itself doesn’t usually control the brake hold function directly. Instead, the steering wheel may allow you to activate or adjust other related systems while driving, or it can help you manage different driving modes that integrate with the brake assist systems.

Here’s how the brake hold function typically works in AMG vehicles and how you can use it, including interactions with the steering wheel:

1. Understanding Brake Hold Functionality

The brake hold function is designed to maintain brake pressure automatically, preventing the vehicle from rolling forward or backward when you are at a complete stop, such as at a traffic light or in stop-and-go traffic. This feature is especially useful in automatic transmission vehicles like AMG models.

When activated, the system holds the brakes after you stop, so you don't need to keep your foot on the brake pedal. Once you press the accelerator, the system releases the brakes automatically, allowing for a smooth start.

2. Activating Brake Hold Function

To activate brake hold in AMG vehicles, it typically requires enabling the feature using the center console button or through the infotainment system.

• Via Center Console Button:
  • Look for the Brake Hold button, usually located near the gear shifter or center console. The button is often labeled with a brake symbol and the words “Brake Hold.”
  • Press the Brake Hold button to enable the feature. You may see a confirmation message or an indicator light on the instrument cluster or MBUX screen that confirms the system is activated.
• Via Infotainment System:
  • In some AMG vehicles, the brake hold feature can also be activated through the MBUX infotainment system or vehicle settings.
  • Use the steering wheel controls to navigate the infotainment screen, then go to the vehicle settings or driving assistance settings and enable Brake Hold.

3. Using the Steering Wheel to Adjust Related Systems

While the AMG steering wheel does not directly control the brake hold system, it plays a role in managing driving modes and related features that might affect how the brake hold function operates. Here’s how:

• AMG Drive Modes:
  • The AMG Dynamic Select system allows you to adjust different driving modes such as Comfort, Sport, and Race.
  • When you change the driving mode using the steering wheel-mounted drive mode selector or buttons, you may adjust how the vehicle responds to braking and acceleration. For example, in Sport or Race modes, the system may modify how brake hold or other brake assist functions operate for a more dynamic driving experience.
• Steering Wheel Buttons:
  • Some AMG models have buttons on the steering wheel that can help adjust specific vehicle settings, like suspension stiffness or traction control. While these settings may not directly affect brake hold, the wheel controls can help you optimize the car's overall performance, which may complement features like brake hold.

4. Using Brake Hold Function While Driving

Once Brake Hold is enabled:

• At a Stop: When you bring the vehicle to a complete stop, the system will automatically engage the brake hold function to prevent the car from rolling.
• Starting Again: When you press the accelerator, the system will automatically release the brakes, allowing you to move forward smoothly.
  Note: You do not need to press the brake pedal again after stopping, as long as brake hold is activated.

5. Disabling Brake Hold

To disable the brake hold system, you typically have two options:

• Press the Brake Hold button again: This will deactivate the function, and the vehicle will return to normal braking behavior.
• Shift to Reverse or Park: In some AMG models, shifting the car into Park or Reverse may automatically deactivate brake hold.

6. Brake Hold and Hill Start Assist

In AMG vehicles equipped with hill start assist, brake hold works together with this feature to prevent the car from rolling backwards when you’re stopped on an incline. When brake hold is enabled:

• Hill Start Assist will hold the brakes on an incline for a few seconds, giving you time to switch from the brake pedal to the accelerator without the vehicle rolling back.

Conclusion:

The AMG steering wheel itself does not directly control the brake hold function, but it can help you adjust related settings, like driving modes, that may influence the overall behavior of the brake assist systems. The brake hold feature is typically activated through the center console button or infotainment settings, allowing the car to hold the brakes automatically when you come to a stop. This feature is especially useful in heavy traffic or when driving in urban environments, as it reduces the need to keep your foot on the brake pedal.
