To check and add windshield washer fluid on your Kia XCeed, follow these simple steps: Locate the windshield washer fluid reservoir, typically found under the hood near the front of the car. Remove the cap of the reservoir and check the fluid level. If the level is low, pour washer fluid into the reservoir until it reaches the recommended level, which is usually indicated on the reservoir itself. Use a funnel if necessary to avoid spills. Be sure to use windshield washer fluid specifically designed for vehicles, as regular water or other solutions may not be suitable and can damage the system. Replace the cap securely when finished.
