PRIUS c_U (OM52E68U)■
When disconnecting the 12- volt battery terminals
Always disconnect the negative (-) terminal first.
■ After recharging/reconnecting the 12-vo lt 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.
WARNING
■ Chemicals in the 12-volt battery
The 12-volt battery contains 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.
■ Where to safely charge the 12-volt battery
Always charge the 12-volt battery in an open area. Do not charge the 12-
volt battery in a garage or closed room where there is insufficient ventila-
tion.
■ When disconnecting the 12- volt battery terminals
Always disconnect the negative (-) terminal first. If the positive (+) terminal
is disconnected first and touches a surrounding metal surface it may cause
sparks resulting in a fire or it may result in an electric shock, death or seri-
ous injury.
■ How to recharge the 12-volt battery
Only perform a slow charge (3.5 A or less). The 12-volt battery may explode
if charged at a quicker rate.
