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 deteriorating during storage, proper maintenance is necessary.
Perform the following maintenance service for the HV battery and 12-volt auxiliary battery.
NOTE:
^
After the auxiliary battery terminals have been reconnected, the power windows and sliding roof must be initialized.
^
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 ignition switch is turned to the "START" position, the hybrid system
may not start. In this case, turn the key to "START" 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.
