When trouble arises

■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.
●The engine switch mode is memorized by the vehicle. When the battery is recon-nected, the system will return to the mode it was in before the battery was discharged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery discharged, be especially careful when reconnecting the battery.
●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
repairers.

■Vehicle customization
●When the speed-detecting automatic door lock and shift-linked automatic door lock are both on, the door lock operates as follows.
• When shifting the shift lever to any position other than P, both side the doors will be
locked. • If the vehicle is started with both side doors locked, the speed-detecting automaticdoor lock will not operate.
• If the vehicle is started with any door unlocked, the speed-detecting automatic door lock will operate.
●When the smart entry & start system is off, the entry unlock function cannot be custom-ized.
●When the doors remain closed after unlocking the doors and the timer activated auto-
matic door lock function activates, signals will be generated in accordance with the operational signal (Emergency flashers) function setting.
●Some settings can be changed using a switch or the audio system screen. If a setting is
changed using a switch, the changed setting will not be reflected on the audio system screen until the engine switch is turn ed off and then to IGNITION ON mode.
■When customizing using the Remote Touch or Lexus Display Audio controller
Stop the vehicle in a safe place, apply the parking brake, and shift the shift lever to P. Also, to prevent battery discharge, leave the engine running while customizing the features.
WARNING
■During customization
As the engine needs to be running during customization, ensure that the vehicle is
parked in a place with adequate ventilation. In a closed area such as a garage, exhaust gases including harmful carbon monoxide (CO) may collect and enter the vehicle. Thismay lead to death or a serious health hazard.
NOTICE
■During customization
To prevent battery discharge, ensure that the engine is running while customizing fea-
tures.
