Hello all,

I'm brand new to this forum site. I own a 2004 LS430.

Recently, I was sitting in my LS430 and running the power (ac/radio) with engine off for a long time. Then I had a beeping noise and battery light come flashing on. Is that just a warning that I was almost close to running the juice out of the battery?

 

Probably. See your owners manual to be sure; it explains the various warning lights.
