Maintenance and care
Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following 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 smart entry & start system may not be possi-
ble immediately after reconnecting the 12-volt battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the doors.
Start the engine with the engine switch in ACCESSORY mode. The engine
may not start with the engine switch turned off. However, the engine will
operate normally from the second attempt.
The engine switch mode is recorded by the vehicle. If the 12-volt battery is
reconnected, the vehicle will return the engine switch mode to the status it
was in before the 12-volt battery was disconnected. Make sure to turn off
the engine before disconnect the 12-volt battery. Take extra care when con-
necting the 12-volt battery if the engine switch mode prior to discharge is
unknown.
If the system will not start even after multiple attempts, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped professional.
CAUTION
Chemicals in the 12-volt battery
Batteries contain poisonous and corrosive sulfuric acid and may produce
hydrogen gas which is flammable and explosive. To reduce the risk of death
or serious injury, take the following precautions while working on or near the
12-volt battery:
Do not cause sparks by touching the 12-volt battery terminals with tools.
Do not smoke or light a match near the 12-volt battery.
Avoid contact with eyes, skin and clothes.
Never inhale or swallow electrolyte.
Wear protective safety glasses when working near the 12-volt battery.
Keep children away from the 12-volt battery.

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.
