• Lighting control sensor (rain sensor) has been installed in the upper part of the windshield to sense the raindrops and windshield wiper can be operated when the ignition switch is at ON and wiper switch is at AUTO position.
• The lighting control sensor detects the raindrops on the windshield surface using the optical element, and it automatically switches the windshield wiper operation, depending on the amount of rainfall, to the intermittent or LO/HI operation.
• The lighting control sensor detects the raindrops using the reflections of infrared rays, and depending on the amount of rainfall, it automatically adjusts the wiping speed.
• Dry windshield: All infrared rays emitted from the emitter diode are reflected by the windshield and directed to the receiver diode as they are.
• Wet windshield: Part of the infrared rays emitted from the emitter diode are transmitted to outside of the windshield through the raindrops, and the infrared rays with reduced intensity are directed to the receiver diode.
  NOTE: Using the customization function, the rain sensitive wiper function can be invalidated (Refer to CUSTOMIZATION FUNCTION  ).
