Replacing the wiper blades
Important safety notes
GWARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
windshield wiper arm without a wiper blade
and it falls onto the windshield, the windshield
may be damaged by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
!To avoid damaging the wiper blades, make
sure that you touch only the wiper arm of the
wiper.

Care241
Maintenance and care
Z

If water no longer forms "beads" on the paint
surface, use the paint care products recommen-
ded and approved by Mercedes-Benz. This is the
case approximately every three to five months,
depending on the climate conditions and the
care product used.
If dirt has penetrated the paint surface or if the
paint has become dull, the paint cleaner recom-
mended and approved by Mercedes-Benz
should be used.
Do not use these care products in the sun or on
the hood while the hood is hot.
XUse a suitable touch-up stick, e.g. MB Touch-
Up Stick, to repair slight damage to the paint-
work quickly and provisionally.
Matte finish care
!Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to shine.
!The following can give the paint a glossy
appearance and thus reduce the matt effect:
RRubbing hard with unsuitable agents
RWashing the vehicle in direct sunlight
!Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax, for the
purpose of paintwork care. These products
are only suitable for high-gloss surfaces. Their
use on vehicles with matte paintwork leads to
considerable surface damage or, more spe-
cifically, to shiny, spotted areas.
Always have paintwork repairs carried out at a
qualified specialist workshop.
!Only use automatic car washes which cor-
respond to the latest technological stand-
ards. Never use wash programs which finish
by treating the vehicle with hot wax.
Observe these notes if your vehicle has a clear
matte finish. This will help you to avoid damage
to the paintwork due to incorrect treatment.
These notes also apply to light alloy wheels with
a clear matte finish.
iUse only insect remover and car shampoo
from the range of approved Mercedes-Benz
care products.
Cleaning the vehicle parts
Cleaning the wheels
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
!Do not park your vehicle for a long period of
time directly after cleaning, particularly after
cleaning the wheel rim with wheel cleaner.
Wheel cleaner can lead to the increased cor-
rosion of the brake discs and pads. Therefore,
drive for a few minutes after cleaning. By
heating up the brakes, the brake discs and
pads dry. The vehicle can then be parked for a
long period of time.
Cleaning the windows
GWARNING
You could become trapped by the windshield wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or
wiper blades.
!Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows. Do
not touch the insides of the windows with
hard objects, e.g. an ice scraper or ring. There
is otherwise a risk of damaging the windows.
!Clean the water drainage channels of the
windshield and the rear window at regular
intervals. Deposits such as leaves, petals and pollen may under certain circumstances pre-
vent water from draining away. This can lead
Care243
Maintenance and care
Z

to corrosion damage and damage to elec-
tronic components.
XClean the inside and outside of the windows
with a damp cloth and a cleaning product that
is recommended and approved by Mercedes-
Benz.
Cleaning the soft top
!Never use any of the following to clean the
soft top:
Rgasoline
Rthinner
Rtar or stain remover
Rother organic solvents
!Remove bird droppings immediately, as
they are corrosive and can therefore cause
the soft-top fabric to leak. Do not wash the
vehicle with a power washer or in a car wash
that uses power washers. Do not use sharp-
edged equipment to remove ice and snow.
XLight soiling: you can clean the soft top while
it is dry or rinse it with clear water.
XNormal to heavy soiling: clean the soft top
with a brush and clear water. Clean stains and
other dirt with a brush and soft top cleaning
agents that have been recommended and
approved by Mercedes-Benz. Always brush
from front to back, following the grain of the
fabric.
Frequent cleaning reduces the soft top's resist-
ance to dirt.
To restore this resistance to dirt, clean the soft
top using soft top cleaning agents that have
been recommended and approved by
Mercedes-Benz.
Incorrect cleaning and care, as well as aging,
can cause the soft-top seams to leak. In the
event of this happening, have the soft-top seams
sealed at a qualified specialist workshop.
iCover the soft top appropriately if you plan
to leave the vehicle outside for a long period
of time.
Cleaning wiper blades
GWARNING
You could become trapped by the windshield wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield orwiper blades.
!Do not pull the wiper blade. Otherwise, the
wiper blade could be damaged.
!Do not clean wiper blades too often and do
not rub them too hard. Otherwise, the graph-
ite coating could be damaged. This could
cause wiper noise.
!Hold the wiper arm securely when folding
back. The windshield could be damaged if the
wiper arm smacks against it suddenly.
XFold the windshield wiper arms away from the
windshield.
XCarefully clean the wiper blades with a damp
cloth.
XFold the windshield wiper arms back again
before switching on the ignition.
Cleaning the exterior lighting
!Only use cleaning agents or cleaning cloths
which are suitable for plastic light lenses.
Unsuitable cleaning agents or cleaning cloths
could scratch or damage the plastic light len- ses.
XClean the plastic lenses of the exterior light-
ing using a wet sponge and a mild cleaning
agent, e.g. Mercedes-Benz car shampoo or
cleaning cloths.
Cleaning the mirror turn signals
!Only use cleaning agents or cleaning cloths
that are suitable for plastic lenses. Unsuitable
cleaning agents or cleaning cloths could
scratch or damage the plastic lenses of the
mirror turn signals.
XClean the plastic lenses of the mirror turn sig-
nals in the exterior mirror housing using a wet
sponge and mild cleaning agent, e.g.
Mercedes-Benz car shampoo or cleaning
cloths.
