Hicas question

After starting my 91 240, and letting it warm up, after running for a few minutes the Hicas warning light comes on. I see no difference in the handling of the car but I don't know if I should be concerned or is it just one of those 240sx quirks in the car. Any thoughts are greatly appreciated.

check your power steering fluid level

Hum, that is the most obvious thing that it could be.....and something that I didn't even think of. Thanks Spitz.
