I did try searching but didn't find any answers to my questions.

1. Do the 2011 IS250’s have carbon build up problem?
2. Tranny service – I see no mention of changing the fluid in the service schedule. Is it required?
3. Why are spark plugs changed at 60K? Most companies are 100K now.
4. How do I program my remote to lower the windows?


Thanks guys!

1. Don't know
2. Lexus says it is lifetime fluid, for me I would change it at 100K or earlier to be safe.
3. Don't know, all I know is it is a bugger to get to
4. Should be programmed already. Hold down lock button on fob for a few seconds

I believe all IS250s have the carbon build up problem.

I think all is250s has carbon issues. Lifetime tranny fluids. The oem spark plugs are rated at 100k miles but most change out @60k miles for better gas mileage. Windows going down should be already programed. I believe you hold on to the unlock button on your key remote for a couple of seconds to use that feature. Programing it? Never did and don't know.

I'm guessing that the 11's are still too new to have thr build up. Most have the older models.
Here's a link to changing the differential fluid. It says in the manual if you look what you're supposed to do and I believe it's a sealed transmission and you're not supposed to change it. It also tells you to change the plugs at 60K.
