6468-2. Customization
LS600h/LS600hL_EE(OM50G20E)
■Vehicle customization
●When the smart entry & start system is off, the entry unlock function cannot be cus-
tomized.
●When the doors remain closed after unlocking the doors and the timer activated
automatic door lock function activates, signals will be generated in accordance
with the operational signal (Emergency flashers) function settings.
■When customizing using the Remote Touch
Stop the vehicle in a safe place, apply the parking brake, and shift the shift lever to P.
Also, to prevent 12-volt battery discharge, leave the hybrid system operating while
customizing the features.
CAUTION
■During customization
As the hybrid system needs to be operating 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 12-volt battery discharge, ensure that the hybrid system is operating
while customizing features.
