
Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following precautions before
recharging:

If recharging with the 12-volt 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
disconnecting 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 hap-
pens, 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 battery is
reconnected, the vehicle will return the "POWER" switch mode to the
status it was in before the battery was disconnected. Make sure to turn
off the power before disconnect the battery. Take extra care when con-
necting the 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 any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional.
