Uniform TireQualityG rading Standards
Aunifor mstandard to grade the quality of tires
with regards to tread quality, tire traction and
temperature characteristics. The quality grad-
ing assessmentism ade by the manufacturer
following specification sfrom the U.S .govern-
ment .The ratings are molded int othe sidewall of
the tire.
Recommended tir epressures
The recommended tire pressure applies to the
tires mounted at the factory.
The Tire and Loading Information placard con-
tains the recommended tire pressures for cold
tires on afully loaded vehicle and for the maxi-
mum permissible vehicle speed.
The tire pressure table contains the recommen-
ded pressures for cold tires for various operat-
ing conditions, i.e. differingl oad and speed con-
ditions.
Increased vehicle weight due to optional
equipment
The combined weight of all standard and
optional equipment available for the vehicle,
regardless of whether it is actually installed on
the vehicle or not.
Rim
This is the part of the wheel on which the tire is
mounted.
GAWR (Gross Axle Weight Rating)
The GAWR is the maximum gross axle weight
rating. The actual load on an axle must never
exceed the gross axle weight rating. The gross
axle weight ratin gcan be found on the vehicle
identification plate on the B-pillar on the driver's
side.
Speed rating
The speed ratin gispart 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 includin gfuel, tools, the spare wheel,
accessories installed, occupants, luggage and
the drawbar noseweight ,ifapplicable. The gross
vehicle weight must not exceed the gross vehi-
cle weight ratin gGVWR as specified on the vehi-
cle identification plate on the B-pillar on the
driver'ss ide.
GVWR(Gross Vehicle Weight Rating)
The GVWR is the maximum permissible gross
weight of afully loaded vehicle (the weight of the
vehicle includin gall accessories, occupants,
fuel, luggage and the drawbar n
oseweight
,if
applicable). The gross vehicle weight ratin gis
specified on the vehicle identification plate on
the B-pillar on the driver'ss ide.
Maximum loaded vehicle weight
The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optional
equipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa corre-
sponds to1psi. Another unit for tire pressure is
bar. 100 kilopascals (kPa) are the equivalent of
1b ar.
Load index
In addition to the load-bearin gindex ,the load
index may also be imprinted on the sidewall of
the tire. This specifies the load-bearin gcapacity
more precisely.
Curb weight
The weight of avehicle with standard equipment
includin gthe maximum capacityoff uel, oil and
coolant .Italso includes the air-conditionin gsys-
tem and optional equipment if these are instal-
led in the vehicle, but does not include passen-
gers or luggage.
Maximum load rating
The maximum tire load is the maximum permis-
sible weight in kilogram sorlbs for which atire is
approved.
Maximum permissible tir epressure
Maximum permissible tire pressure for one tire.
Maximum load on one tire
Maximum load on one tire. This is calculated by
dividing the maximum axle load of one axle by
two.

The antifreeze concentrate/corrosion inhibitor
concentration in the engine cooling system
should:
Rbe at least 50%. This will protectthe engine
cooling system against freezin gdown to
approximately -35 ‡(-37 †).
Rnot exceed 55% (antifreez eprotection down
to -49 ‡[-45 †]) .Otherwise, hea twilln ot be
dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibito rconcentrate in accordance
with MB Specifications for Service Products
310.1.
iWhe nthe vehicl eisfirst delivered, it is filled
with acoolant mixture thate nsures adequate
antifreeze and anti-corrosion protection.
iThe coolant is checked with every mainte-
nance intervalataq ualified specialist work-
shop.

Important safety notes
GWARNING
Windshiel dwasher concentrate coul dignite if
it comes into contact with hot engine compo-
nents or the exhaust system. There is arisk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
!Only use washer flui dthat is suitabl efor
plastic lam plenses, e.g. MB SummerFi torMB
WinterFit. Unsuitabl ewasher flui dcoul ddam-
age the plastic lense softhe headlamps.
!Only MB SummerFi tand MB WinterFit
washer flui dshould be mixed together. The
sprayn ozzles may otherwise become
blocked. Do not use distille
dorde-ionized water, other-
wise, the leve lsensor may give afals ereading.
When handling washer fluid, observe the impor-
tant safety notes on service products
(
Ypag e344).
At temperatures above freezing:
XFill the washer flui dreservoir with amixture of
water and windshield washer fluid, e.g. MB
SummerFit.
Add 1part MB SummerFi tto100 parts water.
At temperatures below freezing:
XFill the washer flui dreservoir with amixture of
water and washer fluid, e.g. MB WinterFit.
For the correct mixing ratio refer to the infor-
mation on the antifreeze reservoir.
iAdd windshield washer fluid, e.g. MB Sum-
merFit or MB WinterFit, to the washer flui dall
yea rround.
Climate control systemr efrigerant
Important safety notes
The climate control syste mofyourvehicleisf il-
led with refrigerant R ‑134a.
The instructio nlabel regarding the refrigerant
type use dcan be found on the radiator cross
member.
!Only the refrigerant R ‑134a and the PAG oil
approved by Mercedes-Benz may be used.
The approved PAG oil may not be mixed with
any other PAG oil that is not approved for
R-134a refrigerant. Otherwise, the climate
control syste mmay be damaged.
Service work, such as refilling with refrigerant or
replacing component parts, may only be carried
out by aqualified specialist workshop. All appli-
cabl eregulations, as wel lasSAE standard J639,
must be adhered to.
Always have work on the climate control system
carrie dout at aqualified specialist workshop.
