Make sure the power switch on the charger is off when connecting and disconnecting
●
the charger cables to the battery.

Restart the engine.

Unlocking the doors using the smart access system with push-button start 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 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 disconnect the battery. Take
extra care when connecting the battery if the engine switch mode prior to discharge is
unknown.
If the engine will not start even after multiple attempts at both methods, contact your
Lexus dealer.
