| I get the buzzing clicking sound a lot. I think it's totally normal.
As for leaving the car on I think I read in the manual that you are discouraged from leaving the keys close to the car as it senses their presence and keeps some things ready as it does when you approach it. I have noticed many times that when I walk into the garage with the keys in my pocket that the car turns something on.
What I do sometimes when I turn it off is to make sure the red LED is blinking. Then I know the car is off for sure. If you leave it on and walk away with the keys it will beep to tell you that it is still on. |
