High-pressure cleaning equipment
G
WARNING
The water jet of circular-jet nozzles (dirt grind- ers) can cause damage not visible from the
outside to tyres or chassis components. Com-
ponents damaged in this way can unexpect-
edly fail. There is a risk of an accident.
Do not use high-pressure cleaners with circu-
lar-jet nozzles to clean the vehicle. Have dam- aged tyres or chassis components replaced
immediately.
! Always maintain a distance of at least 30 cm
between the vehicle and the high-pressure
cleaner nozzle. Information about the correct
distance is available from the equipment
manufacturer.
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door gaps, joints etc.
R soft top
R wind deflector net
R electrical components
R battery
R plug connectors
R lights
R seals
R trim elements
R ventilation slots
Damage to seals or electrical components
can lead to leaks or failures.
Cleaning the paintwork !
Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit a qualified specialist workshop. X
Remove impurities immediately, where pos-
sible, whilst avoiding rubbing too hard.
X Soak insect remains with insect remover and
rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse off
the treated areas afterwards.
X Remove coolant, brake fluid, tree resin, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
Care and treatment of matt paintwork !
Never polish the vehicle or the light alloy
wheels. Polishing makes the paintwork shiny.
! The following may cause the paint to
become shiny and thus reduce the matt
effect:
R vigorous rubbing with unsuitable materials
R frequent use of car washes
R washing the vehicle in direct sunlight
! Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax. These
products are only suitable for high-gloss sur-
faces. Their use on vehicles with matt paint-
work leads to considerable surface damage
(shiny, spotted areas).
Always have paintwork repairs carried out at a
qualified specialist workshop.
! Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a clear
matt finish. This will help you to avoid damage to the paintwork due to incorrect treatment.
These notes also apply to light-alloy wheels witha clear matt finish.
i The vehicle should preferably be washed by
hand using a soft sponge, car shampoo and
plenty of water.
i Use only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products. Care
297Maintenance and care Z

Cleaning vehicle parts
Cleaning the soft top !
Never use any of the following to clean the
soft top:
R petrol
R thinner
R tar or stain remover
R other organic solvents
! Remove bird droppings immediately as they
are corrosive and, therefore, can make the
soft-top fabric leak. Do not use high-pressure cleaning equipment to clean the vehicle. Do
not use sharp-edged equipment to remove ice
and snow.
X Light soiling: you can clean the soft top while
it is dry or rinse it with clear water.
X Normal to heavy soiling: clean the roof with
a brush and clear water. Clean stains and
other dirt with a brush and a Mercedes-Benz
recommended and approved cleaning agent.
Always brush from front to back in the direc-
tion 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 ageing,
can cause the soft-top seams to leak. Have the
soft-top seams sealed at a qualified specialist
workshop, e.g. at a Mercedes-Benz Service
Centre.
i Cover the soft top appropriately if you plan
to leave the vehicle outside for a long period
of time.
Cleaning AIRCAP Cleaning the wind deflector
! Do not use high-pressure cleaning equip-
ment to clean the net.
Clean the wind deflector on the windscreen with
the soft top closed.
X Apply the parking brake firmly.
X Vehicles with key: turn the key to position
2 (Y page 139) in the ignition lock. X
Vehicles with KEYLESS-GO: press the
Start/Stop button twice (Y page 139).
X Open the cover on the lower centre console.
The AIRCAP button is under the cover. X
Press AIRCAP button :.
The wind deflector between the windscreen
and the soft top is extended. X
Clean net ;of the wind deflector with a soft
brush or a moist cloth. For heavier soiling,
clean it with the care and cleaning agents
recommended and approved by Mercedes-
Benz and rinse it with clean water.
Cleaning the AIRCAP draught stop
Clean the AIRCAP draught stop with the soft top
open.
X Vehicles with key: turn the key to position
2 (Y page 139) in the ignition lock.
X Vehicles with KEYLESS-GO: press the
Start/Stop button twice (Y page 139).
X Open the soft top (Y page 89).298

Cleaning the exhaust tail pipes G
WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
! Do not clean the exhaust pipe with acid-
based cleaning agents, such as sanitary
cleanser or wheel cleaner.
Impurities combined with the effects of road grit and corrosive environmental factors may cause
flash rust to form on the surface. You can
restore the original shine of the exhaust pipe by
cleaning it regularly, especially in winter and
after washing.
X Clean the exhaust pipe with a care product
tested and approved by Mercedes-Benz.
Cleaning the trailer tow hitch H
Environmental note
Dispose of oily and greasy cloths in an envi-
ronmentally-responsible manner.
! Do not clean the ball coupling with a high-
pressure cleaner. Do not use solvents.
! Please note the care instructions in the
trailer coupling manufacturer's operating
instructions. The ball coupling must be cleaned if it becomes
dirty or corroded.
X Remove rust, e.g. with a wire brush.
X Remove dirt with a clean, lint-free cloth or a
brush.
X After cleaning, lightly oil or grease ball cou-
pling :.
X Check that the vehicle's trailer tow hitch is
working properly.
i You can also have the maintenance work on
the ball coupling and the trailer tow hitch car-
ried out by a qualified specialist workshop. Interior care
Cleaning the display !
For cleaning, do not use any of the following:
R alcohol-based thinner or petrol
R abrasive cleaning agents
R commercially-available household cleaning
agents
These may damage the display surface. Do
not put pressure on the display surface when
cleaning. This could lead to irreparable dam-
age to the display.
X Before cleaning the display, make sure that it
is switched off and has cooled down.
X Clean the display surface using a commer-
cially available microfibre cloth and TFT/LCD
display cleaner.
X Dry the display surface using a dry microfibre
cloth. Care
