The old one (LD vibration) used to be all there was. Now the new one is an extension (in Settings) of the old one, which leads to the confusion. I believe the default is to leave it set as it was (that's what mine was) in my 3. But who knows with all the versions of the software (our first '16' was 16.2).I was thinking the same thing as this. But I think I may have disabled it. Is there a setting to enable or disable this? And where? Also, is there a ABS setting?
