Service bulletin LI4696ER1

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

Auxiliary heater Thermo 300 is discontinued. The Thermo Plus unit will replace the current unit only if the whole unit needs to be replaced. 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.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
