
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 discon-
necting the charger cables to the battery.

After recharging/reconnecting the battery
The engine may not start. Follow the procedure below to initialize the system.
Shift the shift lever to P.
Open and close any of the doors.
Restart the engine.

Unlocking the doors using the smart entry & start system may not be possible
immediately after reconnecting the 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 battery is discon-
nected and reconnected, 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
battery if the engine switch mode prior to the battery being disconnected is
unknown.
If the engine will not start even after multiple attempts at all the methods contact
any authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.
