Typically, the dash lights are designed to dim when the headlights are
on, so that they won't be too bright at night. Do you mean they dim more
than they have in the past, in similar circumstances?

Sounds to me like your Battery may be on it's way out.
If the Battery is over 4 Years old, consider getting a
new one. Another thing to check is the grounding straps
which bolt onth the body and the engine from the
NEGATIVE side of the battery. The place where they
bolt onto the car should be "C-T-B" (Clean Tight & Brite)
This goes for the wires also. Check where they are crimped
for corrosion (green color) in the wire strands. If they are
cut the old O-Lug off, cut back 1/2" of wire and re-crimp
a new O-Lug to the same.

Bottom line is " C-B-T " for all electrical mechanical connections.
Look at em. Tug on em. Wiggle em an see iffen their loose.
Any of the above correct the problem. (also press down on the fuses
under the hood and behind the coin cup with the thumb to be sure they
are seated fully. Road vibration works em loose, press down with a
thumb and listen/feel for a CLICK is a tipoff they were loose.)

I second the recommendation for checking the
battery. I figure a battery is good for 5 years,
less one year for each time it's been drained
flat.

I am not familiar with the 00 model, but maybe this will help.

If you are talking about being really dim in daylight driving, take a look
below the control knobs. My 03 OBW with auto climate control has the word
"bright" there. Just hold that button in for a few seconds, and the control
lights will come up to the level you see without the headlights on. Ditto
for getting them dimmer. Just hold the button to reverse the setting. It
will also reset when the ignition is cycled.
