WARNING
■Cautions during customization
As the hybrid system needs to be operating during customization, ensure that the vehi-
cle is parked in a place with adequate ventil ation. In a closed area such as a garage,
exhaust gases including harmful carbon mo noxide (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.
