Information about Service Arduous operating conditions or increased
loads on the vehicle will require some service
work to be performed more often than for a
vehicle in normal use. Such arduous condi-
tions include regular city driving with frequent
intermediate stops and use in mountainous
terrai noronp oor road surfaces.
For example, if the vehicle is used under ardu-
ous operating conditions, have air filters,
engine oil and oil filters changed frequently
and check the wheels often.F urther informa-
tion can be obtained at a qualified specialist
workshop, e.g. a Mercedes-Ben zService
Centre. Fuel/water separator
H
Environmental note
Dispose of service products in an environ-
mentally-responsible manner. !
If you continue driving without having the
fuel/water separator serviced, this could
cause damage to the engine. Any resulting
damage is not covered by the warranty.
If the fuel/water separator needs servicing,
the following message appears in the multi-
function display: You will also hear a brief warning tone.

Visit a qualified specialist workshop as
soon as possible. Care
General notes
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or

295Maintenance and care Z

Cleaning the G-Class Cabriolet soft top
!
Never use any of the following to clean the
sof ttop:
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 soft
top with a brush and clear water. Clean
stains and other heavy soiling with a brush
and suitable soft-top cleaning agents.
Always brush in the direction of the fabric,
from front to back.
Frequent cleaning reduces the soft top's
resistance to dirt.
To restore this resistance, clean your soft top
with Mercedes-Benz Cabriolet care products.
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 spe-
cialist workshop.
i Cover the soft top appropriately if you
plan to leave the vehicle outside for a long
period of time.
Cleaning the wheels !
Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up.
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 inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop.
X Remove impurities immediately, where
possible, 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.
! Never use paint cleaner, buffing or pol-
ishing products, or gloss preserver, e.g.
wax. These products are only suitable for
high-gloss surfaces. Their use on vehicles
with matt finish leads to considerable sur-
face damage (shiny, spotted areas).
Always have paintwork repairs carried out
at a qualified specialist workshop. Care

X
Clean sensors :of the driving systems
with water, car shampoo and a sof tcloth.
Cleaning the reversing camera !
Do not clean the camera lens and the area
around the reversing camera with a high-
pressure cleaner. X
Use clear water and a soft cloth to clean
camera lens :. Cleaning chrome parts !
Do not clean the exhaust pipe with acid-
based cleaning agents such as sanitary
cleansers or wheel cleaners.
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 to the chrome
parts by cleaning the mregularly, especially in
winter and after washing.
X Clean the chrome parts with a chrome care
product tested and approved by Mercedes-
Benz.
Cleaning the trailer coupling 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. Ball coupling
:must be cleaned if it
becomes dirty or corroded.
X After cleaning, lightly oil or grease ball cou-
pling :.
X Check that the vehicle's trailer tow hitch is
working properly.

cially available microfibre cloth and TFT/
LCD display cleaner.
X Dry the display surface using a dry micro-
fibre cloth.
Cleaning the plastic trim G
WARNING
When cleaning the steering wheel boss and
dashboard, do not use cockpit sprays or
cleaning agents containing solvents. Cleaning
agents containing solvents cause the surface
to become porous, and as aresult plastic
parts may break away and be thrown around
the interior when an airbag is deployed, which
may result in severe injuries.
! Do not affix the following to plastic surfa-
ces:
R stickers
R films
R scented oil bottles or similar items
You could otherwise damage the plastic. !
Do not allow cosmetics, insect repellent
or sunscreen to come in contact with the
plastic trim .This maintains the high-quality
look of the surfaces.
X Wipe the plastic trim with a damp, lint-free
cloth, e.g. a microfibre cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
The surface may change colour tempora-
rily. Wait until the surface is dry again.
Cleaning real wood and trim strips !
Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, pol-
ishes or waxes. There is otherwise a risk of
damaging the surface.
X Wipe the wooden trim and trim strips with
a damp, lint-free cloth, e.g. a microfibre
cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
Cleaning the seat covers !
Do not use microfibre cloths to clean gen-
uine leather or artificial leather covers, as
these are too aggressive and, if used often,
may damage the cover.
! Observe the following when cleaning:
R clean genuine leather covers carefully
with a damp cloth and then wipe the cov-
ers down with a dry cloth. Make sure that
the leather does not become soaked. It
may otherwise become rough and
cracked. Only use leather care agents
that have been tested and approved by
Mercedes-Benz. You can obtain these
from a qualified specialist workshop.
R clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. washing-up liquid).
R clean cloth covers with a microfibre cloth
moistened with a solution containing 1% 300
CareMaintenance and care

On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5000 km to 10,000 km depending on
the degree of tyre wear. Maintain the direc-
tion of tyre rotation.
Cleant he contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and
reactivate the tyre pressure monitor
(Y page 327) if necessary. Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
You may fit the spare wheel against the direc-
tion of rotation. Observe the time restriction
on use as well as the speed limitation speci-
fied on the spare wheel. Storing wheels
