cle weight rating (GVWR) specified on the vehi-
cle identification plate at the base of the driver's
seat (
Ypage 276).
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permitted gross
weight of the fully laden vehicle (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 driver seat frame (
Ypage 276).
Maximum weight of the laden vehicle
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 are the
equivalent of 1 psi. Another tire pressure unit is
bar. 100 kilopascals(kPa) are the equivalent of
1 bar.
Load index
In addition to the load bearing index, a load
index can be stamped onto the sidewall of the
tire. It specifies the load-bearing capacity of the
tire more precisely.
Curb weight
The weight of a vehicle with standard equipment
including the maximum filling capacity of fuel,
oil, and coolant. It also includes the air-condi-
tioning system and optional equipme nt i
f these
are installed on the vehicle, but does not include
passengers or luggage.
Maximum tire load
The maximum tire load in kilograms or pounds is
the maximum weight for which a tire is
approved.
Maximum permissible tire pressure
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.
PSI (Pounds per square inch)
Standard unit of measurement for tire pressure.
Aspect ratio
Relationship between tire height and width in
percent.
tire pressure
Pressure inside the tire applying an outward
force to every square inch of the tire's surface.
Tire pressure is specified in pounds per square
inch (psi), in kilopascal (kPa) or in bar. Tire pres-
sure should only be corrected when the tires are
cold.
Cold tire pressure
The tires are cold:
Rif the vehicle has been parked for at least
three hours without direct sunlight on the
tires, and
Rif the vehicle has not been driven further than
1 mile (1.6 km)
Tire tread
The part of the tire that comes into contact with the road.
Tire bead
The tire bead ensures that the tire sits securely
on the wheel. There are several stee l 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
tire bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, a roof rack or a high-performance bat-
tery, are not included in the curb weight and the
weight of the accessories.
TIN (Tire Identification Number)
A unique identification number which can be
used by a tire manufacturer to identify tires, for
example for a product recall, and thus identify
the purchasers. The TIN is composed of the
manufacturer identification code, tire size, tire
model code and manufacturing date.
What you should know about wheels and tires265
Wheels and tires
Z
tional tires, an arrow on the sidewall shows the
prescribed direction of rotation of the tire.
Twin rear tires:if the tires are of identical
dimensions, you can rotate the wheels on the
front axle and the inner wheels on the rear axle
in pairs such that the original direction of tire
rotation is retained. With unidirectional tires,
you may rotate the outside wheels at the rear
axle from one side to the other.
Direction of rotation
Tires with a specified direction of rotation have
additional benefits, e.g. if there is a risk of hydro-
planing. You will only gain these benefits if the
correct direction of rotation is observed.
An arrow on the sidewall of the tire indicates its
correct direction of rotation.
You may mount a spare wheel against the direc-
tion of rotation. Observe the time restriction on
use as well as the speed limitation specified on
the spare wheel.
Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the tires
from contact with oil, grease and fuel.

Diesel
Fuel grade
GWARNING
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gasoline with diesel fuel.
!Filter the fuel before transferring it to the
vehicle if you are refueling the vehicle from
barrels or containers.
This will prevent malfunctions in the fuel sys-
tem due to contaminated fuel.
!You will damage the diesel engine if you do
not refuel with ULSD or a diesel fuel with a
sulfur content of more than 15 ppm.
!Do not use the following:
RMarine diesel
RHeating oil
RBio-diesel
RVegetable oil
RGasoline
RParaffin
RKerosene Do not mix such fuels with diesel fuel and do
not use any special additives. This can other-
wise lead to engine damage. This does not
include flow improver additives. For further
information, see "Flow improvers".
You will generally find information about the fuel
grade on the filling pump. If there is no identifi-
cation on the filling pump, consult a gas station
attendant.

Diesel at very low outside temperatures
GWARNING
If you heat fuel system components, e.g. with
a hot-air gun or open flame, these compo-
nents could be damaged. This can cause fuel
to escape and ignite. Depending on the type
of damage, fuel may also not escape until the
engine is running. There is a risk of fire and
explosion.
Never heat fuel system components. Contact
a qualified specialist workshop to rectify the
malfunction.
Refill only with commercially available ULTRA-
LOW SULFUR DIESEL (ULSD, maximum sulfur
content 15 ppm), which fulfills the ASTM D975
standard.
The flow properties of diesel may be inadequate
at low outside temperatures due to paraffin sep-
aration.
iMalfunctions resulting from paraffin sepa-
ration can only be rectified by heating the
entire fuel system. Park the vehicle in a
heated garage, for example.
To prevent operating problems, diesel with bet-
ter flow qualities is available during the winter
months. You can obtain information at the gas
station or from your fuel supplier.
Your vehicle is equipped with a fuel preheating
system. This improves the flow properties of the
diesel by approximately 46 ‡ (8 †). ULTRA-
LOW SULFUR DIESEL can be used without ris k
o
f malfunction down to an outside temperature
of approximately 14 ‡ ( Ò10 †).

Fuel additives
!Do not add gasoline or kerosene todiesel
fuel to improve its flow characteristics. Gas-
olin e or kerosene impairs the lubricating
properties of the diesel fuel. This can result in
damage to the fuel injection system, for
example.
Information on fuel consumption
HEnvironmental note
CO
2(carbon dioxide) is the gaswhich scien-
tists believe to be prin cipally responsible for
global warming (the greenhouse effect). Your veh icle'sCO
2emissions are directly related to
fuel consumption and therefore depend on:
Reff icie nt use of the fuel bythe engine
Rdriv ing style
Rother non-technical factors, such as envi-
ronmental influences, road conditions or
traff icflow
You can min imize your veh icle'sCO
2emis-
sions by driv ing carefully and having itserv-
iced regularly.
Fuel consumption depends on:
Rthe vehicleversion
Rthe style of driving
Rthe operating conditions
Rthe type or quality of the fuel used
The veh icle will use more fuel than usual inthe
fol lowin g situations:
Rat very low outside temperatures
Rincity traff ic
Rduring short journeys
Ron mountainous terrain
Rwhen to winga trailer
To keep fuel consumption low,observe the
advice inthe "Protection of the environment"
section (
Ypage 24).
The fol lowing components of the different veh i-
cle versions influence fuel consumption:
Rtire sizes, tire tread, tire pressure, tire cond i-
tion
Rbody
Rtransmission ratios for the drive assemblies
Radditional equipment (e.g. air-conditioning
system, auxil iary heating system)
For these reasons, the actual consumption fig-
ures for your vehicle may deviate from the con-
sumption figures determined according to EU
Directive 80 /1268/EE C.
Data concerning fuel consumption are recorded
in the on-board computer; use the steering
wheel buttons to call up the Trip computer
menu (
Ypage 174).
Diesel Exhaust Fluid (DEF)
General notes
HEnvironmental note
Dispose of DEF in an environmentally respon-
sible manner.
When opening the DEF tank filler cap at high
outside temperatures, ammonia vapors may
escape.
Ammonia vapors have a pungent smell and pri-
marily cause irritation of the:
Rskin
Rmucous membranes
Reyes
You may experience a burning sensation in your
eyes, nose and throat, as well as coughing and
watering of the eyes.
Do not inhale ammonia vapors. Avoid contact
with DEF.
Do not allow DEF to come into direct contact
with your skin; it is hazardous to your health.
Rinse any affected areas off with plenty of clean water. Consult a doctor if necessary.
If DEF heats up, e.g. in direct sunlight, in the DEF
supply reservoir for some time to over 122 ‡
(50 †), ammonia vapor will develop.
To conform to emission regulations, you must
operate the vehicle with DEF and refill the supply
regularly. The engine management recognizes
attempts to operate the vehicle without DEF,
with thinned DEF or with another reducing
agent. After previous warning messages, the
engine management then prevents a further
engine start.
When the number of remaining engine starts is 0
the engine management prevents the vehicle
from being driven at a speed exceeding 5 mph

Multi-grade engine oils of the prescribed SAE
class (viscosity) may be used all year round, tak-
ing the outside temperatures into account.
Engine oil viscosity
!If the SAE viscosity class of the engine oil
used does not cover the outside temperature
range in which you are operating the vehicle,
it must be changed in good time, in particular
before the cold season commences. Using an
engine oil that does not have adequate tem-
perature characteristics can lead to engine
damage.
The temperature range information of the SAE
classification always refers to that of fresh oil.
The temperature characteristics of the engine
oil may deteriorate significantly due to aging
in use, especially at low outside tempera-
tures.
We recommend that you change the engine
oil before the cold season commences. Use
an approved engine oil of the specified SAE
class.
Engine oil SAE classification
Viscosity indicates the flow characteristics of a
fluid. If an engine oil has a high viscosity, this
means that it is thick; a low viscosity means that it is thin.
Depending on the respective outside tempera-
tures, select an engine oil according to SAE
classification (viscosity). The table displays the
SAE classification to be used. The low temper-
ature characteristics of engine oils can notice-
ably deteriorate during operation, e.g. from
aging, soot and fuel accretion. For this reason,
regular oil changes using an approved engine oil
from the suitable SAE classification are urgently
recommended.
Additives
!Do not use any additives in the engine oil.
This could damage the engine.
Miscibility of engine oils
!Mixing oils reduces the benefits of using
high grade engine oils.
We recommend that you only add engine oil of
the same quality grade and SAE class as used
when the engine oil was last changed.
If, in exceptional cases, oil of the type in the
engine is not available, top up using another
approved mineral or synthetic engine oil.
If the quality grade is not available for diesel
engines, you may also add engine oils meeting
the requirements in MB Sheet Number 228.5,
229.3 or 229.5. The quantity to be added is then
limited to a maximum of 1 qt (1 l).
12If the quality grade is not available for diesel engines, you may also add engine oils meeting the requirements
of MB Sheet No. 228.5, 229.3 or 229.5. The quantity to be added is then limited to a maximum of 1 qt (1 l).

Information about oil consumption
!If the vehicle is predominantly used for
short-distance driving, this could lead to a
malfunction in the automatic cleaning func-
tion for the diesel particle filter. As a result,
fuel may accumulate in the engine oil and
cause engine failure.
Therefore, if you mainly drive short distances,
you should drive on a highway or on rural
roads for 20 minutes every 310 miles (500 km). This ensures sufficient regenera-
tion of the diesel particle filter.
Depending on the driving style, the vehicle con-
sumes a maximum of 1.0 qt (1.0 l)of engine oil
over a distance of 620 miles (1000 km).
Oil consumption may be higher if:
Rthe vehicle is new.
Ryou mainly operate the vehicle under arduous
operating conditions.
Ryou frequently drive at high engine speeds.
Regular maintenance is one of the preconditions
for moderate rates of consumption.
You can only estimate the oil consumption after
you have driven a considerable distance.
Check the engine oil level on a regular basis, e.g.
weekly or each time you refuel (
Ypage 220).
