moin moin alleben, ich haben einem erdgas-arona, bj. 2019, als Vorführer gebügt. At the start always appear 3 (!) tire symbols, although I have saved the correct tire pressure several times already. What does the caring mean to me? Does the indicator mean that the pressure in 3 tires is not OK, or that a mature false pressure has? If the display is wrong, then what do? Thank you for your hlfe helmut
