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.
■ How to recharge th e 12-volt battery
Only perform a slow charge (5 A or less). The 12-volt battery may explode if
charged at a quicker rate.
■ Emergency measures regarding electrolyte
● 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.
● If electrolyte gets on your skin
Wash the affected area thoroughly. If you feel pain or burning, get medical
attention immediately.
● If electrolyte gets on your clothes
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 disconnecting th e 12-volt battery
Do not disconnect the negative (-) terminal on the body side. The discon-
nected negative (-) terminal may touch the positive (+) terminal, which may
cause a short and result in death or serious injury.
■ 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
explosion.
For replacement of the 12-volt battery, contact your Toyota dealer.

5167-2. Steps to take in an emergency
■When replacing the 12-volt battery
●Use a Central Degassing type 12-volt battery (European Regulations).
● Vehicles without a moon roof: Use a 12-volt battery that the case size is
same as the previous one (LN2), 20 hour rate capacity (20HR) is equivalent
(55Ah) or greater, and performance rating (CCA) is equivalent (345A) or
greater.
Vehicles with a moon roof: Use a 12-volt battery that the case size is same
as the previous one (LN2), 20 hour rate capacity (20HR) is equivalent
(64Ah) or greater, and performance rating (CCA) is equivalent (356A) or
greater.
• If the sizes differ, the 12-volt battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi- cle is not used is a short time, the 12-volt battery may discharge and the
hybrid system may not be able to start.
● Use a 12-volt battery with a handle. If a 12-volt battery without a handle is
used, removal is more difficult.
For details, consult your Toyota dealer. ● After replacing, firmly attach the follow-
ing items to the exhaust hole of the 12-
volt battery.
• Use the exhaust hose that was
attached to the 12-volt battery before
replacing and confirm that it is firmly
connected to the hole section of the
vehicle.
• Use the exhaust hole plug included with the 12-volt battery replaced or
the one installed on the battery prior
to the replacement. (Depending on
the 12-volt battery to be replaced, the
exhaust hole may be plugged.)
