# Service bulletin CA\#9970

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

AUTO GEN START CYCLES THE GENERATOR OFF AFTER BEING STARTED FOR THE AIR CONDITIONER AFTER ONLY 10 MINUTES INSTEAD OF THE INTENDED HVAC TEMPERATURE SETTING BEING REACHED.
