Warning light?

I own a 1994 3000gt.
I bought this car salvage with slight damage last year.
I drive it on a daily basis and it runs and drives perfectly with only 58k original miles on it.
I did not recieve an owners manual for it.
I just had a quick question about a warning light that has recently been displayed on my cluster.
Its an orange light next to the SRS warning light.
I just wanted to know what it means.
It looks like tank w/ fluid. I have checked all of my fluids and did an overall inspection of the car. I found nothing to be wrong.

I just wanted to know what the lights means.

Thanks
