low fuel warning adjustment

[Kenneth Keith]

Hey 200q20v'ers,

Long time no post, but I get the digest so I keep an eye on the topics.  I
have a hopefully quick and easy question for y'all.

My trip computer starts giving me a low fuel warning way early, like at a
half a tank or so.  The fuel gauge seems to be reading fine.  Where can I
adjust the trip computer so it doesn't give me the low fuel warning until
I'm actually low on fuel?  Is that something I need to access on the back of
the instrument cluster?

Thanks,

Kenneth
