Manufacturer summary

Original wording in English

Some customers may complain about an instrument cluster warning message "Auto Light System Malfunction. Turn On/Off Lights Manually". DTC B10AD:09 (Humidity sensor/solar radiation sensor/auto light sensor/rain sensor malfunction) may also be stored with the exterior light warning indicator light ON. This is caused by the rain sensor detecting a temperature higher than the operation range and temporarily stopping the auto light system. As a fail-safe, the low beam headlights are turned on. The auto light system will start to operate normally when the A/C is turned on and the interior temperature drops. To correct this concern, the heat resistance performance of the rain sensor has been enhanced.
