2003 L200 Saturn Automatic - Is bottom right display light in dash for ATF?

I bought a used 2003 L200 without a manual. I'm getting this display light
that the meaning of doesn't just jump out at me.

And has anyone had to change their transmission fluid on their own with this
car? I was looking for a dipstick until I just found out on the 'net that
this doesn't have one...and what looks like the transmission spot is way too
far down to get at easily. So I gotta pay to have it checked?

 

The 4T40-E & 4T45-E
Yeah this is one of those mickey mouse bean counter transaxles where
they want you to come in and pay for servicing while saving 50 cents on
a dipstick... At least it sure as hell seems that way. The car has to
remain level while you take a plug out thats about 2 inches above the
bottem of the pan. Located somewhere between the axle and the engine and
only seen from under the car. Who's bright idea this was I'll never
know. I went ahead and pulled a saturn fans link that should answer your
question.

I forgot to specify the light I wanted to clarify: the one in the lower right
of the instrument panel. It looks like a few hills with something of an arrow
pointing down in the middle of it. I read somewhere else that it is about the
coolant levels.

Thanks for the info and that other link. It sucks, but I want to bring it
somewhere to make sure it is OK...but now I'm a little nervous that I'll just
get someone about as talented as me at this particular item and they'll eff
it up.
