The steering wheel heating function is typically not directly linked to the Adaptive Cruise Control (ACC) system in most vehicles. While ACC manages vehicle speed and distance from other vehicles, it does not generally control or adapt the steering wheel heating. However, in some luxury or performance vehicles, the climate control system (which includes the steering wheel heating) might be adaptive based on external temperature.

Here’s how the steering wheel heating function could behave in relation to external temperatures:

1. Automatic Heating Based on External Temperature:

• In some high-end vehicles, like those with AMG or other premium configurations, the steering wheel heater might be automatically activated when the external temperature drops below a certain threshold (e.g., below 40°F or 5°C). This ensures the wheel is warm enough for the driver without needing to manually turn it on.
• Adaptive Climate Control: Advanced systems can adjust the steering wheel heating based on ambient temperatures. For example, if it's a very cold morning, the system might start heating the steering wheel as soon as you start the vehicle. In warmer weather, the system might disable the heating function to prevent unnecessary energy consumption.

2. Manual Control with Temperature Considerations:

• In most cases, the steering wheel heating function is controlled manually, either via a button on the wheel or through the vehicle’s infotainment system. However, even if manually activated, some systems may automatically turn off after the steering wheel reaches a comfortable temperature or after a certain period, regardless of the external temperature.
• The external temperature can influence when you might choose to turn the heating on or off, but this is generally driver-controlled unless the vehicle has more advanced climate management systems.

3. No Direct Link to ACC:

• Adaptive Cruise Control (ACC) is a driver assistance system that manages speed and distance from other vehicles, and it does not control the steering wheel heating. While ACC may be engaged in cold weather for long drives, it will not activate or adjust the heating function of the steering wheel. That function remains separate and is generally handled by the climate control system.

Conclusion:

The steering wheel heating in some advanced vehicles may be adaptive to external temperatures in that it may activate automatically in cold weather and deactivate when not needed. However, this is not controlled by the ACC system. The heating function operates separately and may include features that adjust based on the external temperature or the vehicle’s internal climate control system.
