Speed Compensated Volume
WARNING: This page is about a different car, the 2014 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The audio DSP module adjusts the audio system volume based on the VSS signal to compensate for wind and road noise.
When a MyKey® is in use and the MyKey® Volume Limiter is enabled, the speed compensated volume is disabled.
