Hello All,

Newbie to this forum and looking forward to sharing experiences with all.

I just picked up my Smoky Granite Mica ISF on May 1st and obviously I'm totally excited and can't wait to be able to put her through her singing class (WOT) in each gear...as legal as possible, of course! lol

I do have a question about the break-in period though, in most of all the threads I've seen, everyone speaks of the period as being 1000 miles-does everyone mean 1000km? The manual actually says 621 miles/1000km.

I would hate to go thru 379 more "conservative"

miles if don't really have to!

600 should do....lol, I opened her up in the first 4 gears with only 30 kms on her.......
They told me she's well broken in at the factory....
Don't sweat it..

I agree with IFSChamp - drive it like you stole it. A couple of hundred miles for a break-in is reasonable, but after speaking with a tech at the Lexus dealership they indicated that driving the heck out of it is a reasonable way to break it in.

I always found that cars tend to run as they are broken-in. As soon as mine had several hundred miles on it I began to push it pretty hard. The main thing my Lexus dealer told me is to not run it at constant RPM. My first 300 miles were on the highway on a trip from Houston to Ft Worth. Even though I was cruising about 80 mph most of the way I frequently put it in manual and changed gears so that the RPM varied between 1800 and 3000.

The car learns how you drive it. After 50 starts, the vehicle "knows" how you drive the vehicle and it can/will adjust to that !! It learns when you shift, how hard you accelarate, when you brake, and even how many times the VSC, TC, ABS gets activated.

Hi there,

Where did you find this information? This is interesting and I did not know about it.

Thanks

I work for Lexus. I'm not a typical sales person either !! I love working/driving and doing anything I can with cars !! I try to learn all the little tricks and whatever I can about them.

Very interesting here, my question is: If it learns how you drive the first 50 times you turn it on, it obviously doesn't know exactly how you drive because you are still breaking it in. Basically you will be fooling this system as you will not be driving it as you will usually be driving after break in...

When I originally leased my 2002 IS300, my plan was to trade it in after the 39 month lease was up. I leased the IS300 with 8 miles on it (3 of them were from my own test-drive), I drove that car "like I stole it", since I was planning on returning it after the lease. 39 months and 22K miles later (I don't put on many miles), I was soo happy with the performance, reliability, and awesomeness of my car that I bought it. I bring my car in for regular service and maintenance and to this day, 7 years later, it still drives amazingly with no problems. The same can not be said for my sisters 2002 BMW 325i. She drove her car very "softly" and always criticized my driving that I would kill my car.
Goes to show Lexus > BMW under all driving conditions.

With my new IS-F, I've been painfully trying to "break it in slowly". Usually works for the first 5 minutes I'm in the car before my right foot starts to get heavy. The 400+ HP just sounds too good not to hear it on every green light.

I have ~500 miles on my IS-F, and I'll probably start driving it harder now.

learning driver behavior is not unique to this car. most modern auto tranmissions will learn and adjust to driver behavior to some extend. that's why it is generally not a good idea to share a car with a spouse who has completely opposite driving style.

What if you bought a demo? How do you reset this learning behaviour? By simply unplugging the battery or do you have to go through a series of combo tricks like performing a video game fighting move?
