BODY D Long exposure to direct sunlight may cause the leather surface to harden and shrink. Keep your vehicle in a shaded area, especially in the summer. D The interior of your vehicle is apt to heat up on hot summer days, so avoid placing on the upholstery items made of vinyl or plastic or containing wax as these tend to stick to leather when warm. D Improper cleaning of the leather upholstery could result in discoloration or staining. Synthetic Leather Areas (Dash and sun visors) The synthetic leather areas may be easily cleaned with a mild soap or detergent and water. First vacuum over the upholstery to remove loose dirt. Then, using a sponge or soft cloth, apply the soap solution to the synthetic leather. After allowing it to soak in for a few minutes to loosen the dirt, remove the dirt and wipe off the soap with a clean damp cloth. If all the dirt does not come off, repeat the procedure. Commercial foaming−type cleaners are also available which work well. Follow the manufacturer's instructions. NOTICE Do not use solvent, thinner, gasoline or window cleaner on the interior. 407
