Rain Sensor Features: 1. The rain sensor activates the wiper when rain is detected. Based on the amount of rainfall, it automatically adjusts the wiper speed to intermittent, slow, or fast settings. 2. The rain sensor switch replaces the original intermittent controller, while the slow and fast speed modes remain functional. Light Sensor Features: 1. The light sensor activates at dusk or when the vehicle enters low-light areas such as tunnels or garages. It automatically turns on the parking lights and dipped headlights. 2. The light sensor switch is integrated with the headlight switch. After starting the vehicle, you can disable the automatic headlight mode using the light control lever to operate the headlights manually. Automatic mode will reactivate upon restarting the vehicle. 3. To preserve battery power for engine starting, the sensor system delays headlight activation by 5 seconds when starting the engine at night.
