Vehicle customization
When the entry function is off, the selecting doors to unlock cannot be cus-
tomized.
When the doors remain closed after unlocking the doors and the automatic
door lock function (time elapsed before the automatic door lock function is
activated if a door is not opened after being unlocked) activates, the signals
will be generated in accordance with the operation signal (buzzers) and the
operation signal (emergency flashers) 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 oper-
ating while customizing features.
