What is the “customize” option and normal Vs ECO and Sport/Sport+? Sure there is a thread to explain if someone has a link to it?

thank you

Have you tried using Customize yet? I don't have that option in my IS 350, but from what I have seen, you can change various aspects of the driving feel like engine response and suspension independently from one another when using Customize.

As for Eco, it just dulls down the throttle and reduces the maximum output of the HVAC system to save fuel. Sport S and S+ progressively get more sporty in feel, with S+ having a firmer suspension.

I encourage you to check out Lexus Drivers and read the owner's manual! It will answer a lot of these new-owner questions.
