Well what do you know, Lexus_DK! Your method worked! I tried it one time and it reset!
How did you know that? I noted this in the Oweners Manual too!
Thanks a million!
P.S. One would think, with all of the buttons in a Lexus, there would one "Maintenance Reset" button under the dash or in the glove compartment to make this process a little easier on the owners.
