(a) Inspection of Voltage Generated by Moon Roof Glass Assembly (Solar Panel)
(1) Park the vehicle in a location with a stable temperature and a sufficient amount of sunlight, and leave the
vehicle as is for approximately 10 minutes.
NOTICE:
To ensure stable generation of voltage by the moon roof glass assembly (solar panel), make sure to park the
vehicle in a location where the system operation conditions reference table are satisfied.
HINT:
The solar ventilation system operates only when the generated voltage is 10 V or higher. Therefore, make sure
to park the vehicle where the system operation conditions reference table are satisfied. This will allow the moon
roof glass assembly (solar panel) to generate a voltage of 10 V or higher.
