the normal operation of the vehicle into
account .Under arduous operating condition sor
increased load on the vehicle, maintenance
work must be carried out more frequently, for
example:
Rregular cit ydrivingw ith frequent intermediate
stops
Rif the vehicle is primarily used to travel short
distances
Ruse in mountainous terrain or on poor road
surfaces
Rif the engin eisoften left idling for long periods
Under these or similar conditions, have, for
example, the air filter, engin eoil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must be
checked more often. Further information can be
obtained at aqualified specialist workshop, e.g.
an authorized Mercedes-Ben zCenter.

Care
Notes on care
HEnvironmental note
Dispose of emptyp ackaging and cleaning
cloths in an environmentally responsible man-
ner.
!When cleaning your car, do not use:
Rdry, coarse or hard cloths
Rabrasive cleaning agents
Rsolvents
Rcleaning agent scontaining solvents
Do not scrub.
Do not touc hthe surfaces and films with hard
objects, e.g. rings or ice scrapers. Otherwise,
you may scratc hordamage the surfaces and
films.
!Do not park your vehicle for along period of
tim edirectly after cleaning, particularly after
cleaning the wheel rim with wheel cleaner.
Wheel cleaner can lead to the increased cor-
rosionoft he braked iscs and pads. Therefore,
drive for afew minutes after cleaning. By
heatin gupthe brakes, the braked iscs and
pads dry. The vehicle can the nbeparked for a
long period of time.
Regular care of your vehicle is acondition for
retainin gthe quality in the long term.
Use care products and cleaning agent srecom-
mended and approved by Mercedes-Benz.
Washing th evehicle and cleaning the
paintwork
Automatic car wash
GWARNING
Braking efficienc yisreduced after washing
the vehicle. There is arisk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
condition suntil full braking power is restored.
!When DISTRONIC PLUS or the HOL Dfunc-
tion is activated, the vehicle brakes automat-
ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOL Dfunction in
the followingors imilar situations:
Rwhen towingthe vehicle
Rin the car wash
!It is preferable to use car washes with
adjustable high-pressure pre-cleaning that
corresponds to the specification for the Cab-
riolet program. In car washes that use high
water pressures, there is arisk that asmall
amount of water may leak int othe vehicle.
238Care
Maintenance and care

Rseals
Rtrim
Rventilation slots
Damaged seals or electrical componentsc an
lead to leaks or failures.
!Do not use high-pressure cleaners if the
tank recess is open while you clean it. This
can cause damage to the seals or other com-
ponents.
Cleaning the paintwork
!Do not affix:
Rstickers
Rfilms
Rmagnetic 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 aqualified specialist workshop.
XRemove dirt immediately,w here possible,
while avoiding rubbing too hard.
XSoak insect remains with insect remover and
rinse off the treated areas afterwards.
XSoak bird droppings with water and rinse off
the treated areas afterwards.
XRemove coolant, brake fluid, tree resin, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid.
XUse tar remover to remove tar stains.
XUse silicone remover to remove wax.
If water no longer forms "beads" on the paint
surface, use the paint care products recommen-
ded and approved by Mercedes-Benz.T his 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,t he 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 asuitable touch-up stick, e.g. MB Touch-
Up Stick,tor epair slight damage to the paint-
work quickly and provisionally.
Mattef inish care
!Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to shine.
!The following can give the paint aglossy
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,tos hiny, 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 aclear
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
ac lear matte finish.
iUse only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products.
Cleaning the decorative film
!The following may have an effect on the ser-
vice life and coloring of decorative film:
Rsunlight
Rtemperature, e.g. hot-air fan
Rweather conditions
Rstone impacts and dirt
Rchemical cleaning agents
Rgreasy substances
!Do not use any types of polish on matt dec-
orative film. Polishing surfaces covered with
film gives it ashiny finish.
!Do not treat matt or structured decorative
film with wax. This may lead to marks that
cannot be removed.
240Care
Maintenance and care

To avoid hazardous situations:
Rnever install snow chains to the front
wheels
Ralwaysinstall snow chains in pairs to the
rear wheels.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have
been specially approved for your vehicle by
Mercedes-Benz,ora re ofacorresponding
standard of quality. For more information,
please contact aqualified specialist workshop.
If you inten dtomount snow chains, please bear
the following points in mind:
RSnow chains may not be mounted on all
wheel/tire combinations. Permissible wheel-
tire combinations (
Ypage 284).
ROnly use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come to aroad that is not snow-covered.
RLocal regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains.
RDo not exceed the maximum permissible
speed of 30 mph (50 km/h).
You may wish to deactivate ESP
®when pulling
away with snow chains installed (Ypage 60).
You can thereby allow the wheels to spin in a
controlled manner ,achieving an increased driv-
ing force (cutting action).

equipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa corre-
sponds to 1psi. Another unit for tire pressure is
bar. 100 kilopascals (kPa) are the equivalent of
1b ar.
Load index
In addition to the load-bearing index, the load
index may also be imprinted on the sidewallo f
the tire. This specifies the load-bearing capacity
more precisely.
Curb weight
The weight of avehicle with standard equipment
including the maximum capacity of fuel, oil and
coolant. It also includes the air-conditioning sys-
tem and optional equipment if these are instal-
led in the vehicle, but does not include passen-
gers or luggage.

missible weight in kilograms or lbs for which a
tire is approved.
Maximu mpermissible tire pressure
Maximum permissible tire pressure for one tire.
Maximu mload on one tire
Maximum load on one tire. This is calculated by
dividing the maximum axle load of one axle by
two.
PSI (pounds per squarei nch)
Astandard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire width
in percent.
Tire pressure
This is pressure inside the tire applying an out-
ward force to each square inch of the tire's sur-
face. The tire pressure is specified in pounds per
square inch (psi), in kilopascal (kPa) or in bar.
The tire pressure should only be corrected when the tires are cold.

Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The wheelb rakes or suspension components
may als obedamaged. There is arisk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equipped with atire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be use dnear
the valve .This coul ddamage the electronic
components.
Only have tires changed at aqualified spe-
cialist workshop.
Always pay attention to the instructions and
safety notes when changing awheel
(
Ypage2 81).
The wearp atterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclearw earp attern
has formed on the tires. Front tires typically
wearm ore on the shoulders and the rear tires in
the center.
On vehicles that have the same size front and
rear wheels, you can rotate the wheels accord-
ing to the interval sinthe tire manufacturer's
warranty book in you rvehicled ocuments. If no
warranty book is available,t he tires should be
rotated every 3,000 to 6,000 mile s(5,000 to
10,000 km) .Depending on tire wear, this may
be required earlier. Do not change the direction
of wheelr otation.
Clean the contact surfaces of the wheela nd the
brake disc thoroughly every time awhee lisr ota-
ted. Check the tire pressure and, if necessary,
restart the tire pressure loss warning system or
the tire pressure monitor.
Directio nofrotation
Tires with aspecified direction of rotation have
additionalb enefits, e.g. if there is arisk of hydro-
planing. These advantages can only be gained if
the tires are installed corresponding to the
direction of rotation.
