Thanks to all. The code is "420".

You need to change the water.

Hmmmm....I would have the codes cleared, then see if the 420 comes back.
That code is associated with the oxygen sensors/catalytic converter
system and, though not impossible, it seems a little early for your car
to have a bad/lazy O2 sensor. And it should be setting the CEL not the
cruise control light. Has this car previously had emissions or engine
work or any odd problems/repairs?
I dunno, seems hinky to me.

Gen IV Legacys flash the cruise control light, indicating that the cruise
control is disabled, when there's a fault that needs urgent attention, it's
documented somewhere in the manual; probably applies to other models of the
same era as well.

P0420 is Catalytic converter efficiency low IIRC, and has been
discussed quite a bit here lately. I'm fighting with that one
myself.
Have your catalytic converter looked at. If it looks reasonable, try
throwing a front O2 sensor at it, and the popular wisdom is that hte
issue is likely to go away.
Cat replacement is what mine needs I think -- mine apparently has a
hole in it (and I replaced the o2 less than a year ago).
