2003 Camry Beep sound Dashboard after 80 kmph no warning sign. I have Toyota Camry Sportivo 2003; Kms done - 212000; Car runs fine below speed of 80kmph but when I accelerate the speed to more than 80kmph it start beeping on the dashboard but there are no warning sign, I was not having any passenger doors were locked, everything looks okay. 2 months back I have changed the Alternator local made, Car is in Melbourne, Australia. Not able to understand what the issue could be. Appreciate in advance, Looking for some directions.
