Help with low idle from Venezuela

[Yarisvene]

Hello everybody; i'm new here but a silent observer 4 months ago; i am from Venezuela and i purchased a new brand Yaris sedan (this is a new model here); mi car has only 1000 mile and since new i noted that the idle of this car is around only 750rpm but the real doubt is when i turn on the air conditioner, the idle down to 600rpm and the car isn't feel quiet at all; there is normal in this model of toyota that the idle down instead up when one turn on the a/c?, is idle at 750rpm normal in this car?, whats your cars idle? thanks in advance.
