Washing

Periodic washing is recommended in order to remove build-up residue and in order to eliminate any weathered appearance.

    • Wash the vehicle in lukewarm or cold water.
         Do not use hot water or wash the vehicle in direct sunlight.
    • Do not use strong soap or chemical detergents.
    • Promptly flush all of the cleaning agents from the surface. Do not allow the cleaning agents to dry on the finish.

Waxing

Your authorized dealer offers several polishes and cleaners that have proven value in maintaining original finish appearance and durability. Protect the painted body surfaces and the chrome plating by using a coating of wax. Use any good base body wax for painted and chrome surfaces. Apply the wax immediately after the vehicle has been cleaned. Do not apply wax to the vehicle in direct sunlight or in extreme heat. Periods between applications should be short enough to ensure continuous protection of the finish.
