work ,f or example.
Specia ls ervice requirementsThe specified maintenance interval takes only
the normal operation of the vehicle into
account .U nder arduous operating condition so r
increased load on the vehicle, maintenance
work must be carried out more frequently, for
example: R
regular cit yd rivin gw ith frequent intermediate
stops R
if the vehicle is primarily used to travel short
distances R
use in mountainous terrain or on poor road
surfaces R
if the engin eiso ften left idling for long periods
Under these or similar conditions, have, for
example, the air filter, engin eo il 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 aq ualified specialist workshop, e.g.
an authorized Mercedes-Ben zC enter.

Care
Maintenance and care

! Lock the car if you wash it in an automatic
car wash. Otherwise, the vehicle might be
damaged.
! Never clean your vehicle in aT ouchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
If you have your vehicle cleaned in ah igh-
pressure automatic car wash, small amounts
of water may enter the vehicle.
! Make sure that the automatic transmission
is in position N when washing your vehicle in
at ow-through car wash. The vehicle could be

The vehicle could otherwise be damaged.
You can clean the vehicle at an automatic car
wash from the very start.
Preferably clean the vehicle at automatic car
washes that use textile washing elements with-
out brushes. This prevents fine scratches from
forming on the paintwork and film.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off wax
from the windshiel da nd the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windshield.
i Vehicles with decorative film: select aw ash
program without hot wax at the automatic car
wash.
Washing by hand In some countries, washing by hand is only
allowed at speciall ye quipped washing bays.
Observe the legal requirements in each country. X
Do not use hot water and do not wash the
vehicle in direct sunlight. X
Use as oft sponge to clean.X
Use am ild cleaning agent, such as ac ar
shampoo approved by Mercedes-Benz. X

tle jet of water. X
Do not point the water jet directly towards the
air inlet or the edges of decorative foils. X
Use plenty of water and rinse out the sponge
frequently. X
Rinse the vehicle with clean water and dry
thoroughly with ac hamois.X
Do not let the cleaning agent dry on the paint-
work or the decorative foils.
Carefully remove all deposits of road salt as
soon as possible when driving in winter.

G WARNING
The water jet from ac ircular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nent sd amage dint his way may fail unexpect-
edly .T here is ar isk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis component sr eplaced imme-
diately.
! Vehicles with decorative foil: parts of your
vehicle are covered with decorative foil. Main-
tain ad istance of at least 27.5 in (70 cm)
between the foil-wrappe dp arts of the vehicle
and the nozzle of the high pressure cleaner.
Information abou tt he correct distance is
available from the equipment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
The water temperature of the high-pressure
cleaner must not exceed 140 °F (60 °C).

Damaged seals or electrical component sc 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: 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 aq ualified specialist workshop.X
Remove dirt immediately ,w here possible,
while 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.
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. X
Use as uitable touch-up stick, e.g. MB Touch-
Up Stick ,tor epair slight damage to the paint-
work quickly and provisionally. Matt ef inish care
! Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to shine.
! The following can give the paint ag lossy
appearance and thus reduce the matt effect: R
Rubbing hard with unsuitable agents R
Washing 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 ac lear
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.
i Use 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: R
sunlight R
temperature, e.g. hot-air fan R
weather conditions R
stone impacts and dirt R
chemical cleaning agents R
greasy substances
! Do not use any types of polish on matt dec-
orative film. Polishing surfaces covered with
film gives it as hiny finish.
! Do not treat matt or structured decorative
film with wax. This may lead to marks that
cannot be removed.240

Speed rating The speed rating is part of the tire identification.
It specifies the speed range for which the tire is
approved.
GVW (Gross Vehicle Weight) The gross vehicle weight includes the weight of
the vehicle including fuel, tools, the spare wheel,
accessories installed, occupants, luggage and
the drawbar noseweight, if applicable. The gross
vehicle weight must not exceed the gross vehi-
cle weight rating GVWR as specified on the vehi-
cle identification plate on the B-pillar on the
driver's side.
GVWR (Gross Vehicle Weight Rating) The GVWR is the maximum permissible gross
weight of af ully loaded vehicle (the weight of the
vehicle including all accessories, occupants,
fuel, luggage and the drawbar noseweight, if
applicable). The gross vehicle weight rating is
specified on the vehicle identification plate on
the B-pillar on the driver's side.
Maximu ml oaded vehicle weightThe maximum weight is the sum of: R
the curb weight of the vehicle R
the weight of the accessories R
the load limit R
the weight of the factory installed optional
equipment
Kilopascal (kPa) Metric unit for tire pressure. 6.9 kPa corre-
sponds to 1p si. 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 sidewal lo f
the tire. This specifies the load-bearing capacity
more precisely.
Curb weight
The weight of av ehicle 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. Maximu ml oad ratingThe maximum load rating is the maximum per-
missible weight in kilograms or lbs for which a
tire is approved.
Maximu mp ermissible tire pressureMaximum permissible tire pressure for one tire.
Maximu ml oad on one tireMaximum load on one tire. This is calculated by
dividing the maximum axle load of one axle by
two.
PSI (pounds per squar ei nch)As tandard 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.
Cold tire pressure The tires are cold: R
if the vehicle has been parked with the tires
out of direct sunlight for at least three hours
and R
if the vehicle has not been driven further than
1m ile (1.6 km)
Tread
The part of the tire that comes into contact with
the road.
Bead
The tire bead ensures that the tire sits securely
on the wheel. There are several steel wires in the
bead to prevent the tire from coming loose from
the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.All about wheel sa nd tires 279
