Probably blonde Q. But in my Nissan Avenir I have a switch marked"Power, AT, Hold."two position rocker switch. Its positioned quite close to the Auto selector lever. Thanks in Advance.

Power resets the change points in the auto transmission - kind of sports/going hard mode.A/T is normal setting.Hold holds the car in one gear (say to use engine braking when going down a steep hill).Just leave it in A/T!

Many thanks geedubu. I'm not sure that #2's explanation was very helpful.

I personally prefer power mode, I find it slightly more economical as you don??

Power gives extra thrust, AT = automatic take-off which means you can let go of the steering wheel and Hold allows you to maintain your altitude without looking at the horizon.
