or component parts.
Doing so may result in death or se rious injury due to electric shock.■

Cautions during customization
As the engine needs to be running 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.

During customization
To prevent battery discharge, ensure that the engine is running while customizing fea-
tures. 1 2
