WARNING
■During customization
As the hybrid system needs to be
operating during customization,
ensure that the vehicle is parked
in a place with adequate ventila-
tion. 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 seri-
ous health hazard.
NOTICE
■During customization
To prevent 12-vo lt battery dis-
charge, ensure that the hybrid
system is operating while custom-
izing features.
