O/D button an ECT button.

So is it good to have them both on or both off? or one on and one off?


what would be better for onroad and what would be better for offorad?

I dot kno bout both on at same time but o/d is better on highway w gas mileage w wat I've heard.

 

Use both. The ETC electronically holds each gear to a higher RPM before upshifting and the OD is just that. If you want slightly better mileage, leave the ETC off and the trans will upshift to the high gear asap unless you are a leadfoot.

 

so for better on-road performance keep the ETC button off and the O/D off?

And for better off-road performance then have both on?

 

For normal point A to point B driving I would have OD on and ETC off. These are things you can play with as the situation calls for. For example, freeway onramps call for ETC on. High-speed freeway calls for OD on. Around town with some hills calls for OD off and ETC off to save gas and provide a little engine brake on slight downgrades. In all it is all about what feels right for your driving style and situation.
Offroad I would have OD and ETC off and work the gearshift manually as needed.

 

The tranny will kick out of OD if you step on it-it will still hunt gears. Matter of fact the ETC tends to cause the tranny to over-downshift on the freeway because its intention is to provide higer RPMs. I leave the ETC off on freeways so the tranny stays in higher gear more.

 

So wouldnt it make more sense if my O/D is off with the ETC button on while offroading? Making higher rpms wouldnt better ?

and for the onroad keep the OD on and the etc off correct? Im guessing that would lower the rpms.

 

IMO you really don't want high RPMs offroad-you want to actually control wheel slippage so ETC off. On road I already explained above and like I said before it is all about what feels right to you at that moment.
Example-engage ETC as you enter an onramp for better gain of speed. Once you are at speed-turn it off so the tranny holds top gear better for mileage.

 

Always turn the overdrive switch on for better fuel economy and quieter driving...If the engine coolant temperature is low, the transmission will not shift into overdrive gear even with the overdrive switch on...

 

ECT or "Power" mode is for a more powerful acceleration...Toyota recommends leaving it off to improve fuel economy...

 

:God I love manuals

 

I like the way the tranny shifts with the power button ON! But, I've found with it ON, I get about 2 mpg less!
So, I leave it off unless I need to get up to speed real fast, it does help a little!
OD is always ON! Unless I've got a trailer behind me, or if the tranny keeps downshifting out of OD on hilly freeways!
