This Is My First Post, So Am Still Apprehensive About How To Do It. Anyway, I Am A New Owner,3 Weeks Now. My Neighbor Has Had A Prius For Several Years And Tells Me That I Will Not Be Able To Leave The Car Parked For Over 2 Weeks Without Driving It Or The Battery Will Die. If This Is True, What Steps Need To Be Done To Prevent This? My Neighbor Has A Friend Come In And Drive It During The Storage Time. Thanks For Any Tips,
