service brakes should be used to stop and hold the vehicle on an
incline. To prevent the vehicle from rolling when starting on an
incline, place both feet on the brake pedal before sliding the right
foot to the throttle pedal. Gradually back off the brake while
applying as little throttle as necessary to move along the incline.

NOTE: Neutral should always be reached before UltraShift power down
is performed except in cases of emergency.
