Yaris Hybrid 2013, questions despite user manual ;0)

Hi together, have a hybrid for 2 days and ask me, which are nowhere (I know) written down. So for example: • can I dim the instrument lighting? • is there no music reduction in navigation announcements? • is there no audio reduction in active parking help? • does Touch&Go not show any covers and contact images? (Bluetooth) • is there comfort light that concerns opening or closing? these are questions I haven’t found in the operator’s book either! Already mentioned in forums and what I find a pity are: • unlit keys (door lock, steering wheel etc) • dimming and driving light weak • parking aid at the front Unfortunately does not switch off after time in case of car standstill. Piept continuously on. • USB connection in impossible place and missing in center console! Does anyone possibly have one or other answer?
