
Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flammable
and explosive. Therefore, observe the following precautions before recharging:

If recharging with the 12-volt battery installed on the vehicle, be sure to discon-
nect the ground cable.

Make sure the power switch on the charger is off when connecting and discon-
necting the charger cables to the 12-volt battery.

After recharging/reconnecting the 12-volt battery

Unlocking the doors using the smart entry & start 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 power switch in ACCESSORY 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 battery 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 possi-
ble to shift into each shift position.
If the system will not start even after multiple attempts at all methods above,
contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
