Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, before recharging:
If recharging with the 12-volt battery installed on the vehicle, be sure to dis-
connect the ground cable.
Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the 12-volt battery.
After recharging/reconnecting the 12-volt battery
Vehicles with a smart entry & start system: Unlocking the doors using the
entry function may not be possible immediately after reconnecting the 12-
volt battery. If this happens, use the wireless remote control or the mechani-
cal 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
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 the
power switch off before disconnect the 12-volt battery. Take extra care when
connecting the 12-volt battery if the power switch mode prior to discharge is
unknown.
When the 12-volt battery is reconnected, start the hybrid system, depress
the brake pedal, and confirm that it is possible to shift into each shift posi-
tion.
If the system will not start even after multiple attempts, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
