The dealer told me there is a "Low Washer Fluid" light. That was in 2020 when I bought the car new. I have never been able to find it. Yesterday I ran out of fluid. Is there a light?

 

I can't say for sure about a 2021 but look for a symbol in the dash area that looks like that below. I might also add that a strict interpretation of the online manual (page 556) makes me think the sensor may only be installed in Canadian models. Note 2nd image from the manual.
