Description and Operation

Description

This system uses a light sensor to automatically turn on the tail lamps and headlamps based on changes in ambient light conditions. It is activated when the vehicle enters or exits a tunnel, or when ambient lighting conditions change due to rain, snow, or fog. The precautions relevant to the use of this system are as follows.

1. 1
   Do not install any other device on top of this device.
2. 2
   Be sure to switch to manual mode in poor visibility conditions, such as fog, heavy rain or cloudy weather.
3. 3
   Light intensity in actual driving conditions is not always constant, and the lamp ON/OFF timing may vary greatly depending on climate, season, and surrounding environment.
4. 4
   Use this system only during sunrise and sunset, and manually adjust the lamp on/off under normal conditions.
5. 5
   A malfunction may occur if a light-blocking coating that may change the interior illumination is applied.
