I suppose it makes sense that the gap decrease button (but not the increase button) turns off follow mode.

Gap decrease button normally closes the gap distance to the car in front, reducing safety and requiring more driver awareness.

Disabling follow mode is an extension of that: holding the button effectively disables the gap-based braking and allows the car to close the gap completely.

I have a related question about Adaptive Cruise Control.

When ACC is braking the vehicle quite firmly (eg due to the car ahead suddenly slowing down) and ACC uses disk brakes rather than just engine braking, does it illuminate the rear brake lights so the driver behind me is aware of the hazard?

I would assume yes for safety/regulations, but I’d like to have it confirmed. The manual doesn’t mention it as far as I can tell.
