■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.

ized.

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.
