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

DP: The subject vehicles are equipped with Toyota Safety Sense \(TSS\) which consists of several driving assist features, including pre\-collision braking, lane departure warning, and more. Due to inappropriate programming of the software within the forward recognition camera, there is a possibility that under certain conditions, TSS functions could become inoperative for approximately 4 seconds before rebooting and becoming operational again.
