Download Cadillac SRX Front Floor Liner Installation Instructions CARE AND USE INSTRUCTIONS Your new floor liner is custom molded to fit your particular vehicle. The liner is made to take the place of your factory floor mats. For correct fit, it is necessary to remove the factory floor mat before installing your new floor liner. However, do not remove the factory-installed carpeting. Your liners are made from an engineering resin that is lightweight and extremely tough and durable. The easiest way to clean your liner is with a damp cloth or sponge. If using a cleaner, 409® or Glass Plus® work well. Use of Armor All®, Son-of-a-Gun® or similar items is discouraged as these products make the liners slick.
