Narrative:

Departed teb runway 24 via teb departure. Initial departure calls for runway heading to 1500 ft turn right to 280 degrees at 4.5 DME from teb VOR climb to 2000 ft thence. After reaching 1500 ft some confusion arose as to when 4.5 DME was to occur. The co-pilot flying read the wrong distance from the FMS progress display and started the climb from 1500 ft to 2000 ft earlier than 4.5 DME from teb VOR. The departure controller advised of the early climb and stated the correct departure procedure. There was no conflict with another aircraft associated with this incident. The biggest contributing factor was human error during the departure procedure. No corrective action was required. Factors affecting the quality of human performance were family stress and lack of sleep.
