Could someone please explain me this necessary step in the refill process:


Apply the parking brake. With your foot firmly on the brake pedal, shift the car through each gear position, pausing briefly in each gear.


When putting the system in manual mode, with foot on the brake, the highest gear I can reach (for a couple of seconds before it automatically returns to gear 1) is the 3rd one.


How can you shift trough all the gears when the car is standing still?


The BMW service information states this process and every other DIY on the web... am I missing something?
