the way it works depends on many things. drive mode selected, % grade, speed at any particular grade, using manual shift mode.... I use 'normal' mode with manual shift in the moutains and it works fairly well. I don't give it high marks because my truck does it soo much better but the truck has actual transmission braking. it is within reason for a SUV or car though. most transmissions don't have real braking function which is why its called engine braking.
one thing I read is that eco drive mode allows the transmission to coast, so that would be very bad to use in hilly driving.
if the hill is long and grade steep enough to overwhelm the engine, the rpm will rise and you'll have to brake. this usually means you should have been in a lower manual gear, that will provide more engine braking leverage
