Narrative
Departing EWR; we were cleared via the Newark 5 Departure. The aircraft had MEL 32-XX which required that we keep our landing gear down for 7 minutes after departure. After pushback; the Captain notified Clearance that we were going to need to keep the gear down for 7 minutes after takeoff. Just prior to takeoff I asked Tower if they got the message about the situation and the Tower Controller said he received the information and would pass the information on to departure.After takeoff we used NAV… VNAV to fly the SID. Autopilot was engaged approximately 3 DME from IEZA. After 4 DME the aircraft turned to a 290 heading to follow the SID. The Departure Controller asked why we were turning; and we reported that we were following the SID; she then issued a traffic alert. We were IMC at the time but did not receive any TA or RA but were able to see the traffic on the Multi-Function Flight Display (MFD) and there was no further conflict with that traffic.We asked the controller for clarification; and she mentioned that we couldn't start the turn to 290 degrees till we were above 3000 feet prior to crossing the TEB 214 radial; which isn't what the SID plate displays. There was no further conversation with the Departure Controller regarding what happened and she eventually handed us off to NY Center.Cause: Possible incorrect communication between Tower and Departure and not fully understanding the issue with the aircraft and how it affects us compared to being a clean airplane.Suggestions: The Departure Controller could have given us a heading earlier to follow rather than follow the SID if traffic was going to be an issue. Also the controller shouldn't be giving incorrect altitudes like saying it's 3000 feet when it contradicts what the plate says.
