Maintenance and care Waxing your vehicle Wax when water stops beading on the surface. This could be every three or four months, depending on operating conditions. Use only carnauba or synthetic-based waxes. Remove any bugs and tar before waxing vehicle. Use cleaning fluid or alcohol with a clean cloth to remove. Use tar remover to remove any tar spots. Repairing paint chips Minor scratches or paint damage from road debris may be repaired with touch-up paint, repair foil or aerosol paint spray from the Ford accessory line. Observe the application instructions on the products. Remove particles such as bird droppings, tree sap, insect remains, tar spots, road salt and industrial fallout immediately. Cleaning the wheels Wash with the same detergent as the body of your vehicle. Do not use acid-based wheel cleaners, steel wool, fuel or strong detergents. Never use abrasives that will damage the finish of special wheel surfaces. Use a tar remover to remove grease and tar. Cleaning the engine Engines are more efficient when they are clean because grease and dirt buildup keep the engine warmer than normal. When washing: • Take care when using a power washer to clean the engine. The high pressure fluid could penetrate the sealed parts and cause damage. • Do not spray with cold water to avoid cracking the engine block or other engine components. 170
