Ok, I'm stupid. My cl has active seats that support the driver and passenger when cornering, but I can't find anything about this setting in the manual.I Can get to the setting where you have the choice of driver setting 1 or 2, and you use the + - button to change which setting you want, but how do I enter, or does just changing with the + - buttons make the change?I don't really feel much difference in the settings.
