# Service bulletin 1PM\-T6T3X\-10

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

The Polar MyLift system is an optional component that will automatically lift one or more axles when a trailer is unloaded, and deploy all axles as the trailer loads. Some MyLift systems have been observed to contain a pitted pressure switch contact, causing the system not to function as designed. Reliable failure of the component has not been confirmed, and full manual control of the axle lift functions remains intact. However, Polar?s commitment to reliable products leads us to trade out existing MyLift assemblies with an upgraded version.
