Is it safe to switch the car to snow mode each time I hand over my car to valet (NYC has almost no self parking) and switch it back to normal when I get it back? I just want to sure that I don't mess up the electronics as I do that 4-5 times a week.

 

To my knowledge, no, it will not hurt anything. However, I believe it will default to regular operation after it has been shut off and restarted. Therefore, it will be delivered back in the snarl mode.
