The VSC and track on lights on and check engine light what does that mean?

What does VCS with swervy lines under symbol mean?

2007 Lexus RX350 service engine light and vsc light is on and it is not throwing a code what could it be?

I had it come on - all three. I read that it could be to an unexpected imbalance in your load. We were travelling and heavily packed - bikes on a rack that hangs off the trailer hitch. Says to verify oil and primarily anti freeze. All seemed in good order. I disconnected the battery and the lights went out.
