You are absolutely correct! I just replaced the battery, problem solved, thanks a lot.

one more thing, the dash board lights dim when I try to turn on engine

Thanks for your advice, I did try according your suggestion, no success so far. Check fuses, all look fine, the starter doesn't turn over engine and there is no more the click sound. Still trying ...

I am also trying check fuse box, where is it located? how to change it?

LS430 / 2005 has been running well, yet cannot start up this morning without any warning sign, only hear the click sound, all the dash board lights are on, signal lights and emergency light are working, driver side window is not functioning yet all the passenger side window works fine, cannot adjust steering wheel position, cannot horn or turn on head light; I did jump start, but still cannot start the engine, so it is not the battery problem, feels there are something wrong with the electrical system, any suggestion? Thanks in advance. Jeff
