原來 D3 不是這樣用的!
因之前聽人講
D1 拖波
D2 行雪地及濕滑地, 或市區塞車用。
D3 上落斜路及扒頭。
請師兄指正。
hkchengs 發表於 25-5-2016 10:43 You are quite right. My understanding is
1 - going up deep slope
2 - start moving a car on heavy snow to avoid slipping, going down deep slope
D3 - urban driving below 50km/h to reduce gear hunting
D4 - highway driving since 4th gear is overdrive gear which can reduce the fuel consumption at high speed driving. |
