Reduce direct sunlight entering through a compatible vehicle's front windshield while parked with this Windshield Sunshade. Designed to cover a substantial portion of the front glass, the shade can help shield the dashboard, steering area and interior surfaces from direct solar exposure and may reduce heat buildup compared with leaving the windshield uncovered. Actual temperature reduction depends on vehicle design, outside temperature, sunlight intensity, fit and sunshade construction. Install the shade only while the vehicle is safely parked and make sure it is removed completely before driving. Never operate a vehicle with any sunshade obstructing the driver's windshield or field of view. Compare the product dimensions with the vehicle windshield before purchase because fit varies between cars, SUVs and other vehicles. Depending on the model, the shade may fold, roll or use another compact storage method. Exact dimensions, material, reflective layer, fastening method, folding design, color and vehicle compatibility vary by product. Do not describe the item as completely preventing UV exposure or interior heat unless supported by appropriate testing. Allow hot interior surfaces to cool before touching them after prolonged sun exposure.
