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 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
■
The hybrid system may not start. Follow the procedure below to initialize the system.
●
Shift the shift lever to P.
1
Open and close any of the doors.
2
Restart the hybrid system.
3
Unlocking the doors using the smart access system with push-button start 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 sys-
●
tem 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 bat-
tery was disconnected. Make sure to turn off the power switch 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.
If the system will not start even after multiple attempts at all methods above, contact your
Lexus dealer.
