■When recharging or replacing the battery
●In some cases, it may not be possible to unlock the doors using the smart entry & start system when the battery is discharged. Us e the wireless remote control or the mechan-
ical key to lock or unlock the doors.
●The engine may not start on the first attempt after the battery has recharged but will start normally after the second attempt. This is not a malfunction.

●Vehicles with Stop & Start system:
For a while after the battery terminals have been disconnected and reconnected, for a while after the battery has been replaced, the Stop & Start system may not automati-cally stop the engine for approximately 5 to 60 minutes.
■When exchanging the battery (vehicles with Stop & Start system)
Use a battery specified for use with the Stop & Start system and equivalent to a genuine battery. If an unsupported battery is used, Stop & Start system functions may be
restricted to protect the battery.
Also, battery performance may decrease and the engine may not be able to restart. Contact any authorized Lexus retailers or Le xus authorized repairers, or any reliable
