Re: can you tell me what this is and how it works
from a previous thread..... "
Basically all this switch does is cause your car to start in second gear instead of first gear. This decreases the amount of torque power produced at the wheels which reduces slippage and improves your traction control. I don't like the designation "Winter" and "Summer" because starting in second gear is a little hard on your clutch, and you don't want to start in second gear just because it is "Winter" and there are times in the summer where you may want to have improved traction control, such as in the rain. In general, you will definately want the "Summer" setting.
However, in inclement weather conditions where the roads may be slick, such as in snow, ice, or rain, the "Winter" setting will definately help you maintain control of your car during take off from a stop. Of course, if you floor your car, it will simply kick back into first gear anyways. Hopefully you aren't flooring your car in the snow. If you are already moving you will notice no change in your cars performance, this switch only affects your acceleration from a stop when you gently push the accelerator."
