will be prevented.

and dry thoroughly or clean with
Mercedes-Benz approved Leather Care.
Exercise particular care when cleaning per-
forated leather as its underside should not
become wet.Nubuck leather upholstery (CL 55 AMG
and CL 65 AMG)
The nubuck leather upholstery is treated
with a protective coating. Wipe nubuck
leather upholstery with damp microfiber
cloth to remove dust and other light stains.
Carefully dab nubuck leather upholstery
with a dry microfiber cloth to remove oil
stains.Plastic and rubber parts
Do not use oil or wax on these parts.
Wood trims
