Shifting
WARNING: It is the driver's responsibility to always
ensure the vehicle is in Park before exiting. Never
rely on Model 3 to automatically shift into Park for
you; it might not work in all circumstances (for
example, if Creep or a slope causes the vehicle to
travel greater than approximately 2 km/h).
