Speed Compensated Volume
WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The ACM compensates for wind and road noise by adjusting the audio system volume based on the VSS signal and customer-defined setting.
When a MyKey® is in use and the MyKey® Volume Limiter is enabled, the speed compensated volume is disabled.
