■During customization
As the hybrid system needs to be operating during customization, ensure that the vehi-
cle is parked in a place with adequate vent ilation. 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.
