Hi,
I'm new to this forum and grateful for any helpful sugestions. I have a 2007 Rx400h which I have had from new. A couple of weeks ago I noticed a warning buzzer about one minute after starting the engine, whether stationery or driving. As the buzzer sounded the sound system would switch off for a second or two and then come back on. There are no warning lights or messages on the dash or the display. I can't find any reference to it in the manual and I have tried leaving the sound system off, putting the seatbelt on before starting the ignition, the other key fob which is hardly ever used and should have a good battery life,switching off the bluetooth and even pressing the shift lock button. The car is working perfectly, as usual, but this is very frustrating.
Thanking you in advance for any suggestions.
Tony
