Unsprung Vibration Control
WARNING: This page is about a different car, the 2002 Lexus LX 470. However, it is still accessible from the selected car via links, so may be relevant.
If unsprung resonance is detected, this function operates so that damping force will not decrease below a certain level to reduce the unsprung resonance. As a result, road-holding performance is ensured without affecting riding comfort.
