After recharging/reconnecting the battery (vehicles with a smart key sys-
tem)
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 key system may not be possible imme-
diately 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 con-
necting the battery if the engine switch mode prior to the battery being dis-
connected is unknown.

If the system will not start even after multiple attempts, contact your Toyota
dealer.
