When disconnecting the 12-volt battery terminals
■
Always disconnect the negative (-) terminal first.
After recharging/reconnecting the 12-volt battery (vehicles with a smart
■
key 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. How-
ever, 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 reconnected, the vehicle will return the "POWER" switch mode to the sta-
tus it was in before the 12-volt battery was disconnected. Make sure to turn
off the power before disconnect the 12-volt battery. Take extra care when
connecting the 12-volt battery if the "POWER" switch mode prior to dis-
charge is unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.
