BEEP while driving

[andras0]

So while I was driving today in 2007 auris I heard a BEEP. After 5mins again, BEEP. It was short and beeped in intervals of like 5-7mins and BEEPED twice in a row for like 3 times total. Doors closed, fuel tank closed, seat belts fastened, no error on dashboard. Can it be serious?

You got satnav? Could be a speed camera warning?

[andras0]

Nope, no satnav

Could be parking sensors, if you have them, or radio, if it was auto tuning a station. 

According to Auris manual, there's no beep for anything serious. Not in the manner you described.

did you have anything heavy on the passenger seat? if so it could be triggering the seat belt alarm. (Car thinks someone is sat there with no seatbelt on)

I had the same problem due to parking sensors.  After the car had a wash, It went away.
