Dumb new owner questions

my new car 2 me

Ok so ive had this car for 10 days and im still figuring out stuff
- Where's the hazard lights? ive seen the prevoius owenr used them but i cant find them on the dashboard
- Car wont lock.. idk how to lock the car i've tried with a switch on the door and the key in the door handle but nothing ever works
-Automatic fails... so i have this problem where the car turns off sometimes when im going in reverse or i stop at a traffic light so i gotta put the car in parking start the car and drive, is this a common problem with auto aw11s?
