Introduction
The Highlander HV is equipped with 2 types of batteries:
^
Hybrid Vehicle (HV) battery
^
12-volt auxiliary battery
If the Highlander HV 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.
Please perform the following maintenance service for the HV battery and 12-volt 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 12-volt 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.
