Q: Using the 3 2 1 Gears in an automatic.

on2016年7月28日

I've been curious to know what the 3 2 1 are actually there for. It doesn't seem right to use them in an automatic car without risking damage to anything. I guess my question is if you use them for engine breaking, will it damage the vehicle in anyway? I've read things that say, they're there for a reason, but others say that you shouldn't use it.

My car has 54000 miles.
我的车有自动变速箱。

他们是有原因的。传输由计算机控制。它不会让你造成伤害。你必须从一个角度来看它,即它是为了防止转移,而不是强迫转变。

例如,如果您在丘陵地形中驾驶,则使用位置3将防止传输从3到4之间弹跳,然后返回到3.如果您处于停止并转到流量,则使用2将帮助您制动和预防1,2,3 ... 3,2,1一遍又一遍。

使用1来下降雪条件中的陡度是保持控制的最佳方式,而不是任何ABS。发动机制动不会伤害你的动力传动系统。如果您曾经推动了手动传输的汽车,这是一种自然的事件。

自动化脱离发动机制动4th,让汽车海岸用于更好的燃油经济性,但如果您必须骑刹车,它就没​​有意义。如果您以稳定的45英里/小时或更高或更高,请使用4,(驱动器)。您将不得不尝试您的车,以了解您正在驾驶的条件下的感觉。您的用户手册还将为您提供特定于您的汽车的信息。
