# Service bulletin TSB 490

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Newmar has decided to install an override switch for the HWH step to provide a way to operate the step from inside the coach in the event of a sensor or door switch failure. In the event of a step failure, the person\(s\) inside the coach would have a large gap between the door threshold and the ground. The person\(s\) may have to exit via the large gap or the emergency exit door to get out of the coach.
