HICAS Light On = Problem??

[nat04]

Hi all
I have just bought a 93 Skyline GTS-T R32 from a caryard. When driving on the highway, the HICAS light in the dash lights up and stays on until I am off the highway. I rang the car dealer when this first happened and he said it is an indicator light showing that the HICAS is in use.
I am worried that it is a warning light, and need to find out so that if something is wrong, they can fix it (so I don't have to pay later!).
The car drives fine, handles great - does not appear to be anything wrong but the light is coming on...
I havent checked the power steering fluid yet, where is it located?? It also appears to have the factory steering wheel in it.

Thanks
Natalie

do you have an after market steering wheel?
