When the windshield washer fluid is insufficient, the vehicle can still operate normally, but potential risks should be noted. Windshield washer fluid is primarily used for cleaning the windshield. While its absence does not affect core functions such as the engine, it may result in impaired visibility. Particularly during rainy conditions or when insect remains accumulate, thorough cleaning becomes difficult with wipers alone, increasing safety risks. Prolonged operation with an empty washer system may damage the pump motor, and wiper blades will experience accelerated wear due to insufficient lubrication. It is advisable to use professional windshield washer fluid rather than tap water, as it offers comprehensive features including freeze protection, anti-static properties, and insect residue removal, effectively safeguarding both the windshield and wiper components. As part of routine maintenance, regular inspection of windshield washer fluid levels constitutes a critical safety measure for vehicle operation.
