322 OperationVehicle careWe have selected car-care products and
compiled recommendations which are
specially matched to our vehicles and
which always reflect the latest technology.
You can obtain Mercedes-Benz approved
car-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 car-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 car-care
products.Power washer
Tar stains
Quickly remove tar stains before they dry
and become more difficult to remove. A tar
remover is recommended.
!Follow the instructions provided by the
power washer manufacturer on main-
taining 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 connec-
tors, seals, or other rubber parts.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of
water, and a SmartKey with
KEYLESS-GO* is in close proximity, i.e.
within approximately 3 ft (1 m), the ve-
hicle could be inadvertently locked or
unlocked.

Vehicle care
Paintwork, painted body components
Mercedes-Benz approved Paint Care
should be applied when water drops on the
paint surface do not “bead up”. This should
normally be done every 3 to 5 months,
depending on climate and washing deter-
gent used.
Mercedes-Benz approved Paint Cleaner
should be applied if the paint surface
shows signs of embedded dirt (i.e. loss of
gloss).
Do not apply any of these products or wax
if your vehicle is parked in the sun or if the
hood is still hot.
Use the appropriate MB-Touch-Up
Stick for quick and provisional repairs
of minor paint damage (i.e. chips from
stones, vehicle doors, etc.).Engine cleaning
Prior to cleaning the engine compartment,
make sure to protect electrical compo-
nents and connectors from contact with
water and cleaning agents.
Corrosion protection, such as MB Anticor-
rosion Wax, should be applied to the en-
gine compartment after every engine
cleaning. Before applying, all control link-
age bushings and joints should be lubricat-
ed. The poly-V-belt and all pulleys should
be protected from any wax.Vehicle washing
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the underbody, do not for-
get to clean the inner sides of the wheels.!Affixing stickers, adhesive tape or sim-
ilar materials to painted body compo-
nents may damage the paintwork.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of
water, and a SmartKey with
KEYLESS-GO* is in close proximity, i.e.
within approximately 3 ft (1 m), the ve-
hicle could be inadvertently locked or
unlocked.
