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.
