ESE Engine Sound Enhancement (if equipped with NKD)
WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
The ESE feature improves the natural sounds of powertrain and exhaust systems. It uses the microphones and tachometer inputs (under heavy acceleration conditions) to modify the sound and play it back through the speakers. This feature is always enabled and there are no controls to enable or disable the system.
