My RX is a 2016 RX350 with navigation and all the safely features. Last night I saw as strange indicator on the dashboard display behind the steering wheel. It came and went very quickly and displayed an orange circle with a horizontal line through it. I was driving on the highway with the cruise control on. A car was passing me on the left and this indicator briefly flashed. The same thing happened a week ago. I can not find a picture in the manual. My wife thinks it related to the approaching car being too close (which is was). She has the same car but has not seen this particular display. Has anyone seen it or can identify it? Thanks.

 

if you have the lane assist on along with cruise control, that light is likely a reminder to hold the steering wheel firmly...

 

Check out the manual as it shows every indicator light and what it does.

 

Could it be the sway warning? I saw it mentioned on the manual, but it did not describe what type of warning would be displayed.
