The method to activate the headlight cleaning function on the Prado is as follows: 1. Locate a button on the left side of the Prado, below the instrument panel. 2. This button is marked with a headlight spray icon. 3. First, turn on the headlights, then press this switch. 4. Next, press the cleaning function button to initiate the headlight cleaning process. Here are the detailed steps: 1. Find the windshield wiper control lever. Pull the lever toward the direction of the driver's face and hold it. This will cause the spray pump on the bumper to extend and spray windshield washer fluid onto the headlights. 2. Simultaneously, the windshield wipers will start working, and the spray nozzles on the hood will spray washer fluid onto the windshield. 3. Note that when using this function, ensure the washer fluid reservoir has enough fluid. If the fluid level is below the required amount, the system will not spray. 4. During nighttime or low-light driving, rain and dust can significantly reduce the illumination of the headlights, impairing the driver's visibility and posing a safety hazard. 5. Ensuring adequate headlight illumination and providing clear visibility for the driver are critical in such conditions. The headlight cleaning system offers a simple and effective solution to this problem. Many countries now mandate the installation of headlight cleaning systems on vehicles by law.

I often drive long distances, and the headlight washer feature is really useful, especially on muddy roads after rain. Operating the headlight washer on a Prado is simple: First, turn on the headlight switch, either to low beam or high beam. Then locate the windshield wiper control stalk on the right side of the steering wheel, pull it firmly toward you and hold for about two seconds until you hear the hissing sound of water spraying. At this point, two small nozzles near the front bumper will pop out to wash the headlights. Just be careful not to get too close to the vehicle in front while washing, as the spray might drift onto their windshield. If the nozzles aren’t spraying, it could be due to low washer fluid or clogged nozzles—try adding some cleaning solution. In winter when temperatures drop below freezing, it’s best to use antifreeze washer fluid to prevent the pipes from freezing and clogging.

I just came back from a self-drive trip in Tibet. With all the dust on the plateau, the headlight washers were crucial for maintaining visibility. The operation is straightforward: First, start the car; second, turn on the headlights (high or low beam will do); third, grab the windshield wiper control stalk with your left hand and pull it firmly toward you. At this point, both the windshield and headlights will spray water for cleaning, effectively washing away bug remains and mud splatters. A practical tip is to never open the car window while the washer is active, as the cleaning fluid can get blown inside the car by the airflow. Also, this function only works for about 10 seconds each time, so if the headlights are particularly dirty, you may need to repeat the process a few times. And remember to check if the washer motor is functioning properly during every maintenance service to avoid any last-minute failures.

Last time I was driving in the snow up north, I noticed the headlights got covered with snow-melting agent residue, so I immediately used the cleaning function to solve the problem. The operation is actually just two steps: First, turn on the headlight switch—just until the headlight icon appears on the dashboard. Then, simply pull the windshield wiper stalk all the way (the same action as spraying the windshield), and the headlight washers will activate automatically. Note that the headlights must remain on for the cleaning to work; it won’t respond if only the daytime running lights are active. If you notice weak spray pressure, it’s recommended to check the relevant fuse in the fuse box, usually labeled F14. This cleaning function is very efficient with washer fluid, using about 50 milliliters per spray.
