Low engine speed.

Greetings from Russia! I have a question for you. I own Rav4 2018 2.5 (2ar-fe). New car. Idle speed of the motor 750 rpm's. But! When I stop the car (the car is held in place by the brake pedal, the automatic transmission is in the "D" and the air conditioner is off), the idle speed of the motor drops to 580 - 600 rpm's. The motor starts to vibrate and the hood shakes a little. If the air conditioner is turned on, the speed increases to 750 rpm's and there is no vibration. If the car is held by the manual Parking brake (do not press the brake pedal), the speed is also 750 rpm's and there is no vibration. If you release the brake pedal, the speed will also increase to 750 rpm's and the car will start, vibration disappear.
Is it permissible to reduce the idle speed to 580-600 rpm's ? Is it harmful to the engine?

I have the exact same thing going on with mine. Curious. Very curious. Awaiting further discussion.

On the range...

Anybody else wonder about this?

I have noticed the same symptoms and the engine almost seems as if it will stall at such low RPMs
