■ After recharging/reconnecting the battery (vehicles with a smart key
system)
● Unlocking the doors using the smart key system may not be possible
immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.
● Start the engine with the “ENGINE START STOP” switch in ACCES-
SORY mode. The engine may not start with the “ENGINE START STOP”
switch turned OFF. However, the engine will operate normally from the
second attempt.
● The “ENGINE START STOP” switch mode is recorded by the vehicle. If
the battery is reconnected, the vehicle will return the “ENGINE START
STOP” switch mode to the status it was in before the battery was discon-
nected. Make sure to turn off the power before disconnecting the battery.
Take extra care when connecting the battery if the “ENGINE START
STOP” switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.
■ Disconnecting the battery (vehicles with an AUTO ACCESS SEAT)
Do not disconnect the battery while operating the AUTO ACCESS SEAT.
The AUTO ACCESS SEAT will become inoperable.
For details, refer to “AUTO ACCESS SEAT OWNER’S MANUAL”.
