Check your coolant level sounds like it might be low.

Caution on what to put in the LX470 automatic height adjustment system. Dealer said unless correct fluid is put in the system the seals may fail. Specifically warned against break fluid. Cost to repair is over $3,000. I bought a can of the fluid at the Lexus dealer for about $26. The can was approx. 1/2 gallon.
