How to park on a hill. If you are headed down hill, park your car as you normally would then turn the steering wheel far right and slowly let the car gently come up against the curb, set the park brake then put it into park. Parking up hill is the same but instead of turning right turn left and let the car back into the curb gently. Doing it this way you will take the tension off of the parking pawl inside the transmission. You must have a properly operating park brake for this too work.
here's a "justAnswer" thread on the subject...descriptions are virtually identical http://buickforums.com/forums/showthread.php?p=65224
