Where do I got to reset this dang Maintenance Required reminder. I can’t remember for the life of me. Thanks.

 

 

I got this recently as well. You would think that after just getting a oil change Lexus would've done it for me.

No clue how to turn it off. I'm sure it's in the service manual somewhere!

 

Not to go off topic or anything, but I can't for the life of me understand why your cars in North America have cooler oil temperatures and warmer coolant temperatures.
I live in the Middle East and my oil temperature is always half while my coolant temperature is always a at a quarter. All the time...

Note: average temperatures here in the summers are 120F and 70F in the winters.

 

The OEM settings are different. Those gauges aren't terribly accurate either. They're designed to give marketing something to talk about without generating a lot of work for the service department. I don't pay much attention to them unless they're well outside a "normal" indication, and it's pretty clear normal for the General market is not the same as normal for the North American market. Keep in mind, there are no numbers associated with the gauges, so they can show anything Lexus wants them to without anyone questioning them.
