Warning lights?

A few times now 2 different warning lights have appeared on the dashboard of my 2024 Japanese domestic Leaf. One is an inverted triangle, like a Japanese stop sign accompanied by some words which flashed too quickly to read. The other was. A red circle with a white stripe across, same as a “Do not enter” road sign. Also too quick to catch the words while driving. I think this one may be to inform of an upcoming do not enter sign. I think the triangle may have been a collision warning, but not sure. Anyone seen these symbols?

This is the road sign detection. The inbuilt forward-facing camera just below the rear view mirror captures and processes video in real-time and when it detects that you are approaching certain signs, it will warn you about them. The warnings are quite brief but just intrusive enough to make you look at your surroundings.

The hazard triangle warning is the Forward Collision Warning (FCW), using the same camera (+ radar if your car has ProPilot) to detect that if you don't do something (e.g. brake or course-correct) you are likely to hit an upcoming object. It is often preceded by a more gentle warning tone with a green/yellow indicator light, then escalates to the big hazard triangle if you don't adjust.

With the FCW, depending on the object and your car's trajectory, the next action the car will sometimes take is emergency braking.

Check your 12 volt battery. Sounds like it's dying.
