Been following this forum for awhile to gather info on the new IS and I just have a couple of minor questions.

- Does the 250/350 have an onboard computer that tells you your current mileage or MPG or time etc...

- Also how do the power and snow modes on the switch work?

Thanks!

 

Not sure about question one but I want to say yes.
For qustiong two, the way the modes work
Snow engages in 2nd gear, this mimimizes wheelspin in the snow or wet.
Power mode lets the engine and tranny know you want to redline, so the shifts are more aggresive to the redline. In Normal, the shifts are less aggresive to save fuel and be as smooth as possible.

Thanks for responding. Would it hurt the car if you left it in snow mode even on days during the summer to save on gas? Just a theoretical question.

 

No. There have been several of us that have actually tried this method on our own Lexus' and using ECT SNOW doesn't change your fuel consumption one bit. I have to dig out that thread...we've had several discussions about this before.

 

Hmmm interesting. Thanks.

 

Yep it tells you avg mpg, avg mpt, current mpg, avg speed, gear position, and temp I believe.
