You should check your vehicle from time to
time for stone chipping or other damage. Any
damage should be repaired as soon as pos-
sible to prevent corrosion.
In doing so, do not neglect the underbody of
the vehicle. A prerequisite for a thorough
check is a washing of the underbody followed
by a thorough inspection. Damaged areas
need to be re-undercoated.
Your vehicle has been treated at the factory
with a wax-base rustproofing in the body cav-
ities which will last for the lifetime of the
vehicle. Post-production treatment is neither
necessary nor recommended by Mercedes-
Benz because of the possibility of incompati-
bility between materials used in the produc-
tion process and others applied later.
We have selected vehicle-care products and
compiled recommendations which are spe-
cially matched to our vehicles and which
always reflect the latest technology. You can
obtain Mercedes-Benz approved vehicle-care
products at an authorized Mercedes-Benz
Center.
Scratches, corrosive deposits, corrosion or
damage due to negligent or incorrect care
cannot always be removed or repaired with
the vehicle-care products recommended
here. In such cases it is best to seek aid at an
authorized Mercedes-Benz Center.
The following topics deal with the cleaning
and care of your vehicle and give important
"how-to" information as well as references to
Mercedes-Benz approved vehicle-care prod-
ucts.
Power washer
! Follow the instructions provided by the
power washer manufacturer on maintain-
ing a distance between the vehicle and the
nozzle of the power washer.
Never use a round nozzle to power-wash
tires. The intense jet of water can result in
damage to the tire.
Always replace a damaged tire.
Always keep the jet of water moving across
the surface. Do not aim directly at electrical
parts, electrical connectors, seals, or other
rubber parts.
