Control lamps during ignition

Hello, I am proud owner of a Dacia Sandero 1.4 MPI (55kw) in the basic equipment – so without “everything”. After approx. 1,000 km all around satisfied with my petrol. One thing worries me something: when the ignition is activated, the control lamps and warning lights in the small indicator block around the small round function control lamp all light up for a few seconds. All except the turn signal control lamp and the PRE-FILLED CONTROL LAMP. According to my operating instructions, this is At the same time, also light a warning lamp with an electronic fault and MUST light up briefly when pressing the ignition. But does it not … Is this perhaps only true for diesel engines? My dealer only said to me “Don’t worry about it”. What lights up when turning the ignition key to position M with you? All? Also the flasher indicator lamp and the pre-glow control lamp? I would be grateful for your answers.
