■Vehicle customization
●When the smart access system with push-button start is off, the entry unlock function
cannot be customized.
●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
operation buzzer volume and operational signal (Emergency flashers) function set-
tings.
■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.
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.
