Is there a warning
 

I have a 2011SRX and left the car running while I went in to get my hair done.
(my excuse was it was raining out and I did not want to get wet so I hurried:) )
Luckily someone noticed and told me.

My question is should there have been some sort of warning? Maybe there was and I did not hear it? But it was a good 10 minutes that I was in the shop before the gal noticed my wipers were going.

If there was a thief around my car could have been gone. :(
Guess I will be very careful from now on.
Thanks in advance
