Narrative:
On the san jose 8 departure, a turn is supposed to be initiated at 1.8 DME to a 110 degree heading. I attempted to engage LNAV at 1.8 DME and it didn't engage. After reconfiguring flight director to restore VOR/DME information, 20 degrees of left turn had been accomplished and the DME was 3.4. The turn rate was increased and airspeed decreased to accomplish the turn. The maneuver exceeded the 4 DME turn within depicted on the SID to approximately 5.4 DME.
