what is the right temperature for adjusting terios transmission fluid level?

Unfortunately we don't have a manual on this vehicle as it is not offered here in the USA but we always check transmission fluid when the engine is to operating temperature.

Here are a couple standard guides that will help with servicing a unit but they show how to check it when it is filled back up:

Most all vehicles from the early 2000s have a sliding scale that you can check the temperature and then it will tell you where on the dipstick the fluid needs to be for that temperature. That is simply to add the mechanic in cutting down the time they have to wait before checking the fluid.

I would suggest checking your dipstick for a full mark and then just get the engine hot. Then check the fluid and fill it to that mark.

Please let us know if you have other questions on this or still need more info and we will see what we can find. Thanks

thanks a lot. but i still want to know the exact hot operating temperature is it 60 or 65 or 70 or 80 or 90 Celsius and i wonder why not all cars manufacturers write it on the dipstick.

Understood. Unfortunately we don't have a manual on this vehicle so we are not able to provide the exact specs. However, this vehicle is similar to the Toyota Rav 4 and so I provided the spec for this below. These are pretty similar so while your vehicle may be slightly different most are checked between 70 to 80 C.

Hopefully this helps. Thanks
