Procedure For Cleaning The Hood

Maintain a minimum distance of 300 mm between the power washer spray jet and the hood. Do not direct the high-pressure blast directly onto the seals.
Before using the Wash Shampoo, clean highly soiled areas using the power washer (starting at the cowl panel frame and moving towards the hood compartment lid)
