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 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 nor-
mally 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 bat-
tery was disconnected. Make sure to turn off the engine before disconnect the bat-
tery. Take extra care when connecting the battery if the engine switch mode prior
to discharge is unknown.
If the system will not start even after multiple attempts, contact your Lexus dealer.
