Loud beep when turning on and throughout journey

[Lolly12345]

I have had my Toyota Yaris Hybrid 2018 for 4 months now and this morning when I turned on the engine, it made a very loud beep at me - louder than the normal sensors. This flicked between being continuous and intermittent but would go on and off every minute or so. No warning lights came on and nothing on the screen. There were no issues with the car - visually or when moving - so I drove a short distance. The beeping continued for a few seconds every minute or so. I would appreciate any advice!

All doors and boot shut ?  Although that would normally give a display.

Do you have a sat-nav attached ?

Heavy weight on a seat triggering the seat belt warning?

Everything is shut. No heavy weights on the seats. 
 

It’s got built in sat nav. Would that trigger anything??

Hi Laura, I am having a similar problem in my yaris hybrid 2017, while searching I saw your post. What did you do to fix this issue ? Is it any serious issue ?

Thanks
