if it's a US spec '00 it should have drl enabled from factory. make sure the high beam bulbs work, if not, replace them.

My High beam's bulb are working XD
The day time light is disable.
***I searched.
PD do you know what else do i have to check ....wires, fuse or something?

qewani1, is there a label on the fuse box lid in the engine compartment like this one? The label on my 2000 LS400 shows one fuse and one relay for DRL.

I was under the impression that it took more than pulling this fuse and relay to disable DRL.
