To top up your washer fluid, just pop the hood and find the windshield washer reservoir, it's usually a plastic tank with a windshield/water symbol on the cap. Open it carefully, and pour in a premixed washer fluid until you reach the 'full' line. If you accidentally use plain water, it can freeze in cold weather or leave streaks, so stick with the proper blue or green fluid. Close the cap tightly and you're all set for a clear view.
