■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following before recharging:
● If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
● Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the battery.
■ After recharging/reconnecting the battery (vehicles with a smart entry &
start system)
● The engine may not start. Follow the procedure below to initialize the sys-
tem.
Shift the shift lever to P (Multi drive) or N (manual transmission).
Open and close any of the doors.
Restart the engine.
● Unlocking the doors using the smart entry & start system may not be possi-
ble immediately after reconnecting the battery. If this happens, use the wire-
less 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 battery is recon-
nected, the vehicle will return the engine switch mode to the status it was in
before the battery was disconnected. Make sure to turn off the engine
before disconnecting the battery. Take extra care when connecting the bat-
tery if the engine switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts at all methods above,
contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.
