The Adaptive Cruise Control (ACC) system itself does not control or regulate the heating function of the steering wheel. However, in vehicles equipped with a heated steering wheel, the heating function typically works independently of ACC and is designed for driver comfort in cold conditions.

While the exact temperature the steering wheel reaches during use can vary depending on the vehicle make, model, and specific features, heated steering wheels usually provide a range of temperatures for the driver. Here are some general details about how the heating function works:

Typical Heating Temperatures:

• Standard Heating Range: The steering wheel heating system typically provides a temperature range between 95°F (35°C) and 105°F (40°C). This is warm enough to provide comfort in colder weather without becoming uncomfortably hot.
• Multiple Heating Levels: Many vehicles with heated steering wheels, especially premium models or AMG variants like the W465, offer multiple heating levels. You may be able to adjust the heat to a low, medium, or high setting depending on the conditions and your preferences. Higher settings can provide a warmer experience, which is helpful in very cold temperatures.
• Auto Climate Control: Some high-end vehicles can automatically adjust the heating level based on the cabin temperature or external conditions, ensuring that the steering wheel stays warm enough for comfort without overheating.

Activation:

• Manual Control: The heating function is generally activated manually via a button on the steering wheel or the vehicle's center console or through the infotainment system.
• Automatic Activation: In some premium models or certain configurations, the system may automatically activate if the vehicle detects low temperatures, providing comfort without requiring the driver to turn it on manually.

Conclusion:

While ACC does not control the steering wheel heating, the heating function itself typically reaches a comfortable temperature range between 95°F and 105°F (35°C - 40°C). The exact temperature depends on the vehicle and the setting used, with higher settings providing more warmth for cold weather conditions. To ensure comfort during long drives or in cold temperatures, you can manually adjust or activate the heating function as needed.
