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, roof gaps, joints etc.
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
R ventilation slots
Damaged 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
291Maintenance and care Z

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.
Cleaning the plastic trim G
WARNING
Care products and cleaning agents containing solvents can cause surfaces in the cockpit to
become porous. This could result in plastic
parts breaking away when the airbags are
deployed. There is a danger of injury.
Do not use care products and cleaning agents containing solvents to clean the cockpit.
! Do not affix the following to plastic surfaces:
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 temporarily.
Wait until the surface is dry again. 294
CareMaintenance and care

Interchanging the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions. The wheel brakes or suspension components may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with a tyre pressure mon-
itor, electronic components are located in the wheel.
Tyre-fitting tools should not be applied in thearea of the valve, as this could damage the
electronic components.
Only have tyres changed at a qualified spe-
cialist workshop.
Interchanging the front and rear wheels of dif-
fering dimensions can render the general oper-
ating permit invalid.
Observe the instructions and safety notes in the "Fitting a wheel" section (Y page 321).
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear pat-
tern has formed on the tyres. Front tyres typi-
cally wear more on the shoulders and the rear
tyres in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure that the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is
interchanged. Check the tyre pressure and, if
necessary, restart the tyre pressure loss warn-
ing system (Y page 318) or the tyre pressure
monitor (Y page 320). Direction of rotation
Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aqua- planing. These advantages can only be gained if
the tyres are fitted corresponding to the direc-
tion of rotation. An arrow on the sidewall of the tyre indicates its
correct direction of rotation. Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the tyres
against oil, grease, petrol and diesel. Fitting a wheel

Fitting a new wheel G
WARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the wheel bolts to come loose. As a result, you could
lose a wheel while driving. There is a risk of
accident.
Never oil or grease wheel bolts. In the event ofdamage to the threads, contact a qualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving. G
WARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
It is imperative to observe the instructions and
safety notes on "Changing a wheel"
(Y page 321).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been approved for Mercedes-Benz vehicles and the respective
wheel. X
Clean the wheel and wheel hub contact sur-
faces.
X Slide the wheel to be mounted onto the cen-
tring pin and push it on.
X Tighten the wheel bolts until they are finger-
tight.
X Unscrew the centring pin.

tight.
Lowering the vehicle G
WARNING
The wheels could work loose if the wheel nuts and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
X Turn the crank of the jack anti-clockwise until
the vehicle is once again standing firmly on
the ground.
X Place the jack to one side. X
Tighten the wheel bolts evenly in a crosswise
pattern in the sequence indicated (: toA).
The specified tightening torque is 130 Nm.
X Turn the jack back to its initial position.
