  7. Prevent the vehicle from rolling backwards when stopped on a hill or grade, or when the vehicle is starting from a stop on a hill or grade.
    1. To start from a full stop on hill or grade , quickly move your foot from the brake pedal and press firmly on the throttle pedal.
      On steep hills, set the parking brake and release it only when there is enough engine power to prevent rollback.

      On steep hills, set the parking brake and chock the tires, front and/or rear. Never hold a hill with the throttle pedal. This will cause the clutch to overheat.
