Service bulletin LI4968ER1

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.

There is no need to retrofit any buses with the new Thermo Plus units. Replacement parts are available for the current Thermo/Thermo-S units already installed.
