■After charging/reconnecting the 12-volt battery
●Unlocking the doors using the smart key system may not be possible
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 hybrid system with the “POW ER” swi tch in ACC ESSORY 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 bat-
tery 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 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 discharge is unknown.
●Restart the hybrid system, depress the brake pedal, and confirm that it is
possible to shift into each shift position.
If the system will not start even after multiple attempts at all methods above,
contact your Toyota dealer.

●If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immedi-
ate medical attention. If possible, continue to apply water with a sponge or
cloth while traveling to the nearest medical facility.

It can soak through clothing on to your skin. Immediately take off the cloth-
ing and follow the procedure above if necessary.
●If you accidentally swallow electrolyte
Drink a large quantity of water or milk. Get emergency medical attention
immediately.
■When replacing the 12-volt battery
Use a 12-volt battery designed for this vehicle. Failure to do so may cause
gas (hydrogen) to enter the passenger compartment, causing a fire or explo-
sion.
For replacement of the 12-volt battery, contact your Toyota dealer.
