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.

Additives
!Do not use any additives in the engine oil.
This could damage the engine.
Brake fluid
GWARNING
The brake flui dconstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
flui dist oo low,v aporpockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is arisk of an accident.
You should have the brake flui dreneweda t
the specified intervals.
When handling brake fluid, observe the impor-
tant safety notes on service products
(
Ypag e315).
The brake flui dchange interval scan be found in
the Maintenance Booklet.
Only use brake flui dapproved by Mercedes-
Benz in accordance with MB-Freigabe or MB-
Approval3 31.0.
Information about approved brake flui dcan be
obtained at any qualified specialist workshop or
on the Internet at
http://bevo.mercedes-benz.com.
iHave the brake flui dregularl yreplaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Coolant
Important safety notes
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is arisk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly cleant he
antifreeze from components before starting
the engine.
!Only add coolant that has been premixed
with the desired antifreeze protection. You
coul dotherwise damage the engine.
Further information on coolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact aqualified specialist workshop.
!Always use asuitable coolant mixture, even
in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosiona nd
overheating.
iHave the coolant regularl yreplaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products when handling coolant
(
Ypag e315).
The coolant is amixture of water and corrosion
inhibitor/antifreeze concentrate. It performs
the following tasks:
RAnti-corrosion protection
RAntifreeze protection
RRaising the boiling point
If the coolant has antifreeze protection down to -35 ‡(-37 †), the boiling point of the coolant
during operation is approximatel y266 ‡
(130 †).

Technical data

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

Important safety notes
GWARNING
Windshieldw asher 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 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 levels ensor may giveafals ereading. When handling washer fluid, observe the impor-
tant safety notes on service products
(
Ypag

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 system refrigerant
Important safety notes
The climate control system of you rvehicleisf il-
led with refrigerant R ‑134a.
The instruction label regarding the refrigerant
type use dcan be found on the left, on the under-
side of the hood.
!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 system may 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 wellasS AE standard J639,
must be adhered to.
Always have work on the climate control system
carrie dout at aqualified specialist workshop.
