For a full manual you have to move the shifter to the left (S position) then start to use the paddles or to move the shifter forward - backward.
When fully manual the gears are labelled by an "M": M1, M2, etc. on the central display.
@ morfinx to amplify just a bit on javol's post, the term "manual" mode is a bit of a misnomer in a DCT equiped car. Regardless of make, model etc. you really aren't in total control. The exception would be a few of the high end supercars which allow the driver "more" control.

It's sort of like "fly by wire" in a jet - you move the control stick but a computer is actuating vertical and horizontal control surfaces based on millions of data calculations per second. Likewise with a DCT, in some situations the computer just won't let you shift down a gear (e.g., what the computer perceives may damage your drive train), and as mentioned sometime it will upshift without your permission - even in full "manual" mode. In both cases, the DCT (e.g., computer control gear box) is following some higher directives hard coded into the ECU by BMW.
