■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, all the doors will be locked.
• If the vehicle is started with all doors locked, the speed-detecting automatic door 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, signal s will be generated in accordance with the
operation buzzer volume and operational signal (Emergency flashers) function set-
tings.
●Some settings can be changed using a switch or the audio system screen. If a setting is
changed using a switch, the ch anged 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 (if
equipped)
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.
CAUTION
■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. This
may 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.
