REMOVAL OF SMOKE/FUMES is a follow-on procedure and depends on whether or not fuel vapours are present. Basically, if NO fuel vapours: CAB FANS OFF, PACK FLOW HI, set LDG ELEV to 10,000’ or MEA-MORA, DESCEND. At 10,000’ or MEA-MORA, if smoke on cockpit: reduce speed to 200kts, open PM sliding window to clear CKPT smoke.
