Maintenance and care
■After recharging/reconnecting the 12-volt battery
●The hybrid system may not start. Follow the procedure below to initialize the
system.
Shift the shift lever to P.
Open and close any of the doors.
Restart the hybrid system.
● Unlocking the doors using the smart key system may not be possible imme-
diately after reconnecting the 12-volt battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.
● Start the hybrid system with the power switch in ACCESSORY mode. The
hybrid system may not start with the power switch turned off. However, the
hybrid system will operate normally from the second attempt.
● The power switch mode is recorded by the vehicle. If the 12-volt battery is
disconnected and reconnected, the vehicle will return the power switch
mode to the status it was in before the 12-volt battery was disconnected.
Make sure to turn off the power switch before disconnecting the 12-volt bat-
tery. Take extra care when connecting the 12-volt battery if the power switch
mode prior to the battery being disconnected is unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.
