2 instead of D when you drive car on the road coverd with snow

It is more safety to use 2 when you drive on the road covered with snow than to use D.

You may try that, and feel more power to drive your car on the road.

Because,

2 means that small gear to driver larger gear with more power.

But, you should remember that using the 2 only under the speed around 50km/h or 55km/h.

Good lucky,

个人认为自动车在正常情况下可以只用D(RIVE)档. 它的低几档(3,2,1)可以用在如下场合:
- 行驶在很长的下坡路段时, 用于限制下坡速度, 而不依靠刹车装置, 因为长时间踩刹车会使其过热而失效.
- 在需要特别增加牵引力的情况下, 例如上陡坡, 顶强风, 拖后挂车, 开在阻力大的路面(例如积水或积雪).
