WARNING
■Cautions during customization
As the hybrid system needs to be oper ating 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.
