281 Operation
Vehicle care
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 your
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 prod-
ucts.
Additional information can be found in the
booklet entitled "Vehicle Care Guide".
Power washer
When using a power washer for cleaning
the vehicle always observe the manufac-
turer’s operating instructions.Tar stains
Quickly remove tar stains before they dry
and become more difficult to remove. A tar
remover is recommended.
Paintwork, painted body components
Mercedes-Benz approved Paint Care
should be applied when water drops on the
paint surface do not"bead up", normally in
3 to 5 months, depending on climate and
washing detergent 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, vehi-
cle doors, etc.).
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of
water, and a SmartKey with KEY-
LESS-GO* is in close proximity, i.e.
within approx. 3 ft. (approx. 1 m), the
vehicle could be inadvertently locked
or unlocked. !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.

282 OperationVehicle careEngine 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 engine
compartment after every engine cleaning.
Before applying, all control linkage bush-
ings and joints should be lubricated. The
poly-V-belt and all pulleys should be pro-
tected from any wax.
Vehicle washing
Do not use hot water or wash your vehicle
in direct sunlight. Use only a mild car wash
detergent, such as Mercedes-Benz ap-
proved Car Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water. Direct only a very weak
spray towards the ventilation intake. Use
plenty of water and rinse the sponge and
chamois frequently. Rinse with clear water and thoroughly wipe
dry with a chamois. Do not allow cleaning
agents to dry on the finish.
Due to the width of the vehicle, fold in out-
side mirrors prior to running the vehicle
through an automatic car wash to prevent
damage to the mirrors.
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the undercarriage, do not
forget to clean the inner sides of the
wheels.Ornamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome clean-
er.
Headlamps, tail lamps, turn signal
lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
To prevent scratches, never apply strong
force and use only a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of
water, and a SmartKey with KEY-
LESS-GO* is in close proximity, i.e.
within approx. 3 ft. (approx. 1 m), the
vehicle could be inadvertently locked
or unlocked.
