05' factory remote start

I have factory remote start and was wanting to know if it has the option of setting the run time, ( it only runs 10 min. wanting longer). Can't find anything in manual. If so how do you change it?

I was wondering the same thing with my 05 Grand Prix.

I have a 06 with a remote start, and i am unable to make it longer. I think the bcm has somwthing to do with it. I think a dealer can change it, but not sure. Sorry, wish I could help more.
