280 OperationVehicle careUpholstery
Using aftermarket seat covers or wearing
clothing that have the tendency to give off
coloring (e.g. when wet, etc.) may cause
the upholstery to become permanently dis-
colored. By lining the seats with a proper
intermediate cover, contact-discoloration
will be prevented.
Leather upholstery
Wipe leather upholstery with a damp cloth
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.Plastic and rubber parts
Do not use oil or wax on these parts.
Wood trims
Dampen cloth using water and use damp
cloth to clean wood trims in your vehicle.
Do not use solvents like tar remover or
wheel cleaner nor polishes or waxes as
these may be abrasive.
