Yes, it is possible for the ACC heating function to be reduced or turned off in high-performance driving scenarios, while the AMG U88 system remains active. Here's how this works and why it makes sense for high-performance driving:

1. Driver Customization and Control:

• In most high-performance vehicles like the G-Class with the AMG U88 system, there is typically a way for the driver to independently control various comfort and performance features. The ACC heating function is designed to enhance driver comfort in cold conditions, but in performance-focused driving scenarios, such as track days or aggressive driving, the driver might prefer to turn it off to maximize steering feel and reduce any distractions or excess warmth.
• The U88 system focuses on enhancing the steering response and performance feedback. It allows the driver to engage more direct and dynamic steering adjustments without interference from the heating system.

2. Separate Controls for Comfort and Performance:

• Steering wheel heating and steering feedback (via U88) are often controlled separately within the vehicle's settings. During performance driving, the ACC heat function can be manually reduced or completely turned off to prevent any loss of feedback or comfort interference, while the U88 system continues to provide the adjustments necessary for precise steering and handling.
• Some vehicles might have driving modes (e.g., Track, Sport+, or Off-road) that automatically adjust both the steering feedback and comfort features such as the heating based on the demands of the drive. For example, in Track mode, the heating function might be disabled, while the U88 system enhances steering feel to handle high-speed cornering or aggressive acceleration.

3. Performance Driving and Steering Feel:

• During high-performance driving, such as competitive track driving or spirited cornering, having a heavily heated steering wheel can create an unnatural feeling for the driver, as it could make the wheel feel too soft or slick in their grip. The U88 system can be optimized to provide sharper, more responsive steering, and turning off or reducing the heating function can help maintain a more precise connection between the driver’s hands and the steering wheel.

4. Temperature Control and Safety:

• Some vehicles offer a smart system that automatically adjusts or deactivates the heating when the vehicle enters high-performance modes, ensuring that the driver is not distracted by excess warmth and that the steering wheel remains optimized for precise, responsive handling.

5. Independent Operation:

• The ACC heating function and AMG U88 system are designed to function independently. Therefore, the heating system can be turned off without affecting the U88 steering feedback, ensuring that the driver has the flexibility to adjust both the comfort and performance settings based on their needs.

Conclusion:

In high-performance driving scenarios, the ACC heating function can be reduced or turned off, while the AMG U88 system remains active, providing the driver with precise and dynamic steering feedback. This setup ensures that the driver’s steering experience is not compromised by comfort features, allowing them to focus fully on handling and performance without interference from warmth or distraction.
