What's the low washer fluid warning light Lexus type?

Lexus will illuminate a light on the dash when Your washer fluid is low in Your vehicle. This fluid is used to spay off the windshield when You pull back on the wiper stalk and that will help clean debris and dust off of it when You are driving. I recommend using any washer fluid that is rated to zero degrees or below. This will prevent the fluid from freezing in cold conditions. If You live in a place where it never freezes then You can simply add distilled water to the reservoir and that will work for spraying off Your windshield. There are many different fluid options at auto parts stores and all of them will work in Your vehicle.
