HBAssist is potentially availbale when both headlight switch is in "A" position AND lights are turned ON (due to low environmental light condition). Only then you can activate HBAssist manually (Switch ON with steering wheel switch). In case sufficient environmental light (driving through tunnel or so) the Auto lights turn off which consequentially RESETS the HBAssist. You have to turn it on manually again when lights turn ON. Also daylight changes in this period of year, so there are less conditions where HBAssist is needed; this can be erronuously regarded as a failure.
Now one year driving and still impressed !!
