The ECT PWR function makes the transmission shift more abruptly and offers a sportier driving experiences. The ECT SNOW function retards the shifts, thusly reducing the likely of traction loss on slippery surfaces.

It is a gearbox control switch. when in power the gearbox will rev much higher before changing gear.

l have an IS 300 and l live in Northern Indiana which gets a lot of snow.the snow button is great.it is like extra help in the traction area. I've noticed that you can not go very fast when using this feature but it is great to have on slushy icy roads!
