The vehicle's convertible top should be cleaned often. However, high pressure car washes may cause water to enter your vehicle.

When you hand wash the top, do it in partial shade. Use a mild soap, lukewarm water and a soft sponge. A chamois or cloth may leave lint on the top, and a brush can chafe the threads in the top fabric. Do not use detergents, harsh cleaners, solvents or bleaching agents.

Wet the entire vehicle and wash the top evenly to avoid spots or rings. Let the soap remain on the fabric for a few minutes. When the top is really dirty, use a mild foam-type cleaner. Thoroughly rinse the entire vehicle, then let the top dry in direct sunlight.

To protect the convertible top:

    • After you wash the vehicle, make sure the top is completely dry before you lower it.
    • Do not get any cleaner on the vehicle's painted finish; it could leave streaks.
    • If you decide to go through an automatic car wash, ask the manager if the equipment could damage your top.
