Narrative:
On departure from runway 24 at teb on the teterboro 5 departure; all was set in the FMS; leveled off at the 1500 ft as per departure instructions until a turn to 280 degree. I started the turn as the command bars commanded a climb so I followed and realized the commanded climb was premature and I immediately corrected back to 1500 ft. When queried by the controller I announced my altitude was 1600 ft and I was correcting. The rest of the flight was uneventful.supplemental information from 818513: I then noticed we were climbing above our assigned altitude. The pilot flying immediately started back down to 1500 ft. This is a very busy departure. We take off with the command bars in a go-around position. The pilot flying may have been concerned with the departure and not followed the normal procedure of syncing the command bars after take-off; leading to a continuation of the climb.
