Washing the Vehicle
To preserve the vehicle's finish, wash it often and out of direct sunlight.
Notice: Do not use petroleum based, acidic, or abrasive cleaning agents as they can damage the vehicle's paint, metal, or plastic parts. If damage occurs, it would not be covered by the vehicle's warranty.
Approved cleaning products can be obtained from your dealer.
Follow all manufacturer directions regarding correct product usage, necessary safety precautions, and appropriate disposal of any vehicle care product.
Notice: Avoid using high pressure washes closer than 30 cm (12 in) to the surface of the vehicle. Use of power washers exceeding 8,274 kPa (1,200 psi) can result in damage or removal of paint and decals.
Rinse the vehicle well, before washing and after, to remove all cleaning agents completely. If they are allowed to dry on the surface, they could stain.
Dry the finish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting.
