315Maintenance and care Z

!
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 with
a clear matt finish.
The vehicle should preferably be washed by
hand using a soft sponge, car shampoo and
plenty of water.
Use only insect remover and car shampoo from the range of approved Mercedes-Benz care
products. Cleaning vehicle parts
Cleaning the convertible 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 clean water.
X Normal to heavy soiling: clean the soft top
with a brush and clean water. Clean stains
and other dirt with a brush and soft-top clean-
ing agents recommended and approved by
Mercedes-Benz. Always brush from front to
back in the direction 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. In such a
case, have the soft-top seams sealed at a quali- fied specialist workshop, e.g. at your Mercedes-
Benz Service Centre. Cover the soft top appropriately if you plan to
leave the vehicle outside for a long period of
time.

Cleaning the wheels 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.
! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park up your vehicle for a long period
of time immediately after cleaning, particu-
larly after cleaning the wheel rim with wheel
cleaner. Wheel cleaner may lead to increased corrosion of the brake discs and pads. You
should 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 up for a long period of time.
Cleaning the windows G
WARNING
If the windscreen wipers are set in motion
when cleaning the windscreen or wiper
blades, you could become trapped. There is a danger of injury. 318

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.
! Mercedes‑
AMG C 63 and Mercedes‑ AMG C
63 S with black exhaust pipes: Black chrome trims must not be polished with a chrome
polish as this will cause them to lose their
black shine. To ensure optimum care, the
trims should be rubbed down with a lightly
oiled cloth after each time the car is washed. Commercially available engine and mainte-
nance oils are suitable for use as oil.
In the event of heavier soiling, you may apply a fine lacquer polish with a microfibre cloth.
Remove any excess polish paste after polish-
ing.
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 the vehicle.
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.
The ball coupling must be cleaned if it becomes
dirty or corroded.
X Remove rust on the ball, 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 the ball
coupling.

Preparing the vehicle
Your vehicle may be equipped with: R MOExtended tyres (tyres with run-flat char-
acteristics) (Y page 326)
Vehicle preparation is not necessary on vehi- cles with MOExtended tyres.
R a TIREFIT kit (Y page 325)
R an emergency spare wheel (certain countries
only) (Y page 356)
Vehicles with MOExtended tyres are not equip-
ped with a TIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. win-
ter tyres. A TIREFIT kit can be obtained from a
qualified specialist workshop.
Vehicles with a Mercedes-Benz emergency call
system that are not equipped with a TIREFIT kit:
in the event of a flat tyre, contact the Customer
Assistance Centre for the Mercedes-Benz emer- gency call system (Y page 304).

X Remove the Start/Stop button from the igni-
tion lock (Y page 133).
X Make sure that the passengers are not endan-
gered as they get out of the vehicle. Make
sure that no one is near the danger area while a wheel is being changed. Anyone who is not
directly assisting in the wheel change should,
for example, stand behind the barrier.
X Get out of the vehicle. Pay attention to traffic
conditions when doing so.
X Close the driver's door.
X Place the warning triangle a suitable distance
away (Y page 324). Observe legal require-
ments. Vehicles with MOExtended tyres
(tyres with run-flat characteristics)
General notes With MOExtended tyres (tyres with run-flat char-
acteristics), you can continue to drive your vehi-
cle even if there is a total loss of air in one or
more tyres. The affected tyre must not show any clearly visible damage.
You can recognise MOExtended tyres by the
"MOExtended" marking that appears on the tyre
sidewall. You will find this marking next to the
tyre size designation, the load-bearing capacity
and the speed index.
MOExtended tyres may be used only in conjunc- tion with an activated tyre pressure loss warning system or tyre pressure monitor.
If a tyre pressure loss warning message
appears on the multifunction display:
R observe the instructions in the display mes-
sages (Y page 265)
R check the tyre for damage
R if driving on, observe the following notes
The driving distance possible in run-flat mode is
approximately 80 km when the vehicle is parti-
ally laden and approximately 30 km when the
vehicle is fully laden.
In addition to the vehicle load, the driving dis-
tance possible in run-flat mode depends on the:
R vehicle speed
R road condition
R outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions/ manoeuvres, or it can be increased through a
moderate style of driving.
The driving distance possible in run-flat mode iscounted from the moment the tyre pressure loss
warning appears on the multifunction display. 326
Flat tyreBreakdown assistance

!
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 351).
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, while rear
tyres wear more in the centre.
On vehicles that have front and rear wheels of
the same size, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure 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 347) or the tyre pressure
monitor (Y page 349). 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 in a cool, dry and preferably dark
place if they are not being used. Protect the
tyres against oil, grease, petrol and diesel. Fitting a wheel
