Yaris 2013 engine braking problem?

[pikador]

Hello everyone,

When i'm searhing about my problem, i found this great forum.

My car is a Yaris with automatic CVT transmission. When im driving downhill at D mode and apply some braking to slow down, transmission always choses the lowest ratio and engine rpm gets high. Normally when i first buy the car, this was not occured( my be i dont realised). At D mode, i dont feel any engine brake at first, but lately this problem occurs.

Is it a problem or a normal operatin?

Thanks in advance.
