How to Turn on the Crown Headlight Cleaning Device?
3 Answers
The method to turn on the Crown headlight cleaning device is: 1. Start the vehicle and turn on the high and low beams; 2. Lift the windshield washer switch and hold it for 3 seconds to activate the headlight washer mode; 3. Spray water to clean the headlight covers. The headlight cleaning device is mainly used on vehicles equipped with xenon headlights, which offer advantages such as energy efficiency, high brightness, high color temperature comfort, and long lifespan. The Crown is a mid-to-large-size sedan under FAW Toyota, with a body length of 5020mm, width of 1805mm, height of 1480mm, and a wheelbase of 2925mm. In terms of configuration, the Crown is equipped with driver and front passenger airbags, front side airbags, front and rear head airbags, knee airbags, passive pedestrian protection, seatbelt reminder, rear child seat interface, ABS anti-lock braking system, brake force distribution, brake assist, traction control, and vehicle stability control.
I drive a 2018 Crown, and the headlight washer is actually quite useful. Usually, you just need to turn on the headlights first, then operate the wiper stalk as you would for the windshield washer, holding down the washer switch. At this time, while the windshield is being sprayed, the small nozzles under the headlights will extend and spray water. However, there are two things to note: First, the vehicle must be in the started state to operate; second, the headlight washer will only activate the first time you spray after starting the car. Subsequent sprays won't trigger it, as this is a protective mechanism set by the manufacturer. I typically use it when driving on the highway at night in the rain—when the windshield gets dirty, I clean the headlights at the same time, which is especially convenient. After cleaning, the headlight beam becomes noticeably clearer, making driving much safer.
Friends who own the Crown, here's how I operate the headlight washer: After starting the engine, first turn on the headlights, then directly use the wiper control stalk on the right side of the steering wheel and hold the washer button for more than 2 seconds. At this point, you'll hear a buzzing sound from the front of the car, indicating the washer nozzles are operating. Here's the key point—many owners don't know the activation conditions for this feature: the headlights must be on and the vehicle speed must be below 50km/h for it to work. I think this design is quite reasonable as it prevents accidental activation and wasting washer fluid. Also, a reminder: after washing, remember to check if the nozzles have retracted. If they remain extended for too long, they can accumulate dust and get stuck. Once, I didn't notice this, which caused them to jam during the next wash, requiring a trip to the dealership for repair.
