Vehicle specifications
GS350/250_EE (OM30C36E)
Vehicle customization
When the smart entry & start system is off, the “Select doors to unlock”
cannot be customized.
When the doors remain closed after unlocking the doors and the “Auto
relock timer” activates, the signals will be generated in accordance with the
“Lock/unlock feedback lights” 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 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 haz-
ard.
NOTICE

To prevent battery discharge, ensure that the engine is running while cus-
tomizing features.
