除非你拖车或上象Mont Washington那样高的山道, 你应该永远把Overdrive打开(或放在overdrive的挡上), 不然, 你的油耗回很大, 另外在高速时会损于发动机.

在MONTREAL地区(包括在Mont Tremblant)驾驶, 你一直用OVERDRIVE既可.

Why use O/D in MOntreal area?

Overdrive is designed to save gas and protect your engine from overrunning. It should only be turned off if you are towing a heavy load and going up a steep hill (nothing around Montreal/Toronto/Qeubec City area).

Therefore about 99.5% of the time, you should drive on O/D -- unless you are fully loaded and willing to dish out a lot of bucks for the gas!

If I turn on O/D light, that means its function
doesn't work. Usually,O/D light is turned off.
Is it right? Thanks

It works to the opposit:

O/D on = O/D light off
O/D off = O/D light on

You have to make sure the yellow O/D light is off all the time.

over drive的设计原理是不是减少档位的变换幅度？
