What the heck is the function of the ECT button on my car. When do I use it?
Is it for snow? rain? Does it do a job I should be taking advantacge of?

Also, when do I turn the OD off? I think I am supposed to turn it off in snow,
but that is all I know.

Help! I have no idea about cars, clearly!

Thanks,
Kim

From the Toyota Rav4 FAQ @
http://www.faqs.org/faqs/autos/toyota-faq/RAV4

The ECT button (which stands for "Electronically Controlled
Transmission") changes the shift points for the automatic
transmission. When engaged, the transmission shifts later, allowing
the engine to get to a higher power level and accelerate faster. Gas
mileage is usually reduced in this mode. Use it when you need to get
up to speed faster; for example, to merge into fast moving traffic.
The normal position for this switch is OFF.

OD, or OverDrive, is a 4th gear on the transmission that will engage
when you are going above about 35 mph that lets the engine operate
at a lower speed (RPMs) when all it has to do is maintain a high speed
when you are going over flat, even highway. This improves fuel
economy. Technically, any transmission gear with a ratio of less
than 1:1 is considered "OverDrive". OD can normally be left ON
except when going up a gradual hill; the overdrive tends to not
give the engine enough power to maintain a steady speed. This may
cause the transmission to annoyingly "hunt" between 3rd and 4th gear.

I read your response. Thanks for the quick hit back, but I am honestly lucky
I know the make and model of my car. I am a complete idiot. I just want to
make sure that I understand.

The ECT has nothing to do with rain or snow. I only turn it on when I need to
speed up fast.

I leave the OD on almost all the time. Do I turn it off in slippery
conditions?

It changes the personality of the transmission.

The default personality is for economy, shifts come early on the up-shift
side, and are delayed on the down-shift side. When you press the ECT button,
shift points are held longer to provide more power, and down shifts come
earlier to give power sooner. The affect of this is greater fuel
consumption, because of the resulting higher engine speeds.

ECT has nothing to do with snow or ice. Most of the time, most people will
have no reason to press the ECT button. Most people can do the same thing by
simply holding the gas pedal down. Personally, I think that holding the gas
pedal down is silly unless one is entering the freeway.

You should leave the OD on most of the time. A good time to switch it off is
when you are going uphill on the freeway, and the transmission searches for
a gear. It will shift down from OD to 3rd or 4th (whatever is available,
depending on the transmission), then shift back to OD after a few hundred
yards, then downshift again. When this happens you should simply shift out
of OD until you get to the top of the hill.

Well, it depends on the make and model of your vehicle. On my '01
Highlander, the "ECT SNOW" button changes the transmission to allow easier
starts under slippery conditions. I believe it won't let the transmission
into first gear. On my '94 ES300 and '95 Camry, the "ECT PWR/NORM" button
changes the transmission to provide more power as described earlier.

As for the OD button, leave it in normal condition unless the transmission
is hunting between 3 and 4 while straining to go up a hill or to perform
some engine braking to avoid using the brake petal while going down a steep
hill.

You may want to check your owners manual for a description of the features
of your vehicle. It's full of a lot of useful information.

Paul.
