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.
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 the 12-volt battery
Only perform a slow charge (5 A or less). The 12-volt battery may explode if
charged at a quicker rate.

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.
