# Service bulletin T\-SB\-0197\-17\_Rev

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

TSB: REVISION NOTICE May 08, 2018 Rev1: \* Applicability has been updated to include 2019 model year Toyota vehicles. Any previous printed versions of this bulletin should be discarded. Hybrid vehicles are equipped with two types of batteries: \* Hybrid Vehicle \(HV\) battery \- Auxiliary \(12V\) battery If the hybrid vehicle is put into storage, the State\-Of\-Charge \(SOC\) of its HV battery and auxiliary battery will gradually decrease. To prevent the auxiliary battery from becoming discharged during storage, proper maintenance is necessary. Perform the following maintenance service for the HV battery and auxiliary battery. NOTE \- BEFORE disconnecting the auxiliary battery, confirm the shift lever is in the "P" position and apply the parking brake completely. The shift lever CANNOT be shifted from the "P" position with the auxiliary battery disconnected. \* If the negative \(\-\) terminal of the auxiliary battery is reconnected, even if the power button is in the Start mode, the hybrid system may NOT start. In this case, push the Power button and select the Start mode again to start the hybrid system \(the Ready light is ON\). If the hybrid system still does NOT start \(the Ready light is OFF\), refer to the Repair Manual.
