Toyota vitz speedometer and knobs lights goes dimm when parking lights are switched on. If you hold the ODO meter button for few seconds while its on ODO ( not on Trip A/B) then the light of meter will blink full and dimm and you can set it to dimm or full bright.
If full bright is set then it will not be dimm as we switch on parking lights.
Same can be done for seat belt warning buzzer but im searching for it to put it in silent mode. If anyone know sthe method plz share.
