Definitions for tires and loading
Tire structure and characteristics
Describes the number of layers or the number of
rubber-coated belts in the tire tread and the tire
wall. These consist of steel, nylon, polyester,
and other materials.
Bar
Metric unit for tire pressure. 14.5038 pounds
per square inch (psi) and 100 kilopascals (kPa)
are the equivalent of 1 bar.
DOT (Department of Transportation)
DOT marked tires fulfill the requirements of the
United States Department of Transportation.
Average weight of vehicle occupants
The number of occupants for which the vehicle
is designed multiplied by 68 kilograms (150 lbs).
Uniform Tire Quality Grading Standards
A uniform standard to grade the quality of tires
with regard to tread quality, traction and tem-
perature characteristics. The quality grading
assessment is made by the manufacturer fol-
lowing specifications from the U.S government.
The quality grade of a tire is imprinted on the
sidewall of the tire.
Recommended tire pressure
The recommended tire pressures are the pres-
sures specified for the tires mounted on the
vehicle at the factory.
The tire and load information table
1contains the
recommended tire pressures for cold tires, the
maximum permissible load and the maximu
m
permissible vehicle speed.
The tire pressure table contains the recommen-
ded tire pressure for cold tires under various
operating conditions, i.e. loading and/or speed
of the vehicle.
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.
Wheel rim
The part of the wheel on which the tire is moun-
ted.
GAWR (Gross Axle Weight Rating)
GAWR is the maximum gross axle weight rating.
The actual load on an axle must never exceed
the gross axle weight rating. You can find the
maximum gross axle weight rating on the B-pillar
on the driver's side (
Ypage 305).
Speed index
The speed index is part of the tire identification. It specifies the speed range for which the tire is
approved.
GTW (Gross Trailer Weight)
GTW is the total of weight of a trailer and the
weight of the load, accessories etc. on the
trailer.
1Only for vehicles with a gross weight of less than 10,000 lbs (4536 kg).
296What you should know about wheels and tires
Wheels and tires

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.
Load bearing index
The load bearing index (also load index) is a code
that contains the maximum load bearing capa-
city of a tire.
Traction
Traction is the result of friction between the tires
and the road surface.
TWR (permissible trailer drawbar load)
The TWR is the maximum permissible weight
that may act on the ball coupling of the trailer
tow hitch.
Wear indicator
Narrow bars (tread wear bars) that are distrib-
uted over the tire tread. If the tire tread is level
with the bars, the wear limit of áin (1.6 mm)
has been reached.
Distribution of the vehicle occupants
The distribution of vehicle occupants over des-
ignated seat positions in a vehicle.
Maximum permissible payload weight
Nominal load and goods/luggage load plus
68 kg (150 lb s)multiplied by the number of
seats in the vehicle.
Changing wheels
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 wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equipped with a tire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at a qualified spe-
cialist workshop.
Always observe the instructions and safety
notes under "Mounting a wheel" (
Ypage 299).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in the center.
If your vehicle's tire configuration allows, you
can rotate the tires according to the intervals in
the tire manufacturer's warranty book in your
vehicle documents. If no warranty book is avail-
able, the tires should be rotated every 3,000 to
6,000 miles (5,000 to 10,000 km) or earlier if
tire wear requires. Do not change the direction
of rotation.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is rota-
ted. Avoid oily or greasy cleaning agents.
Check the tire pressure and reactivate the tire
pressure monitor if necessary.
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.

Wheels and tires

iE10 fuel contains an admixture of up to 10%
bioethanol. Your vehicle is E10 compatible.
You can refuel your vehicle with E10 fuel.
iUsually you will find information about the
fuel grade on the filling pump. If there is no
identification on the filling pump, consult a
gas station attendant.
If the recommended fuel is not available, you
may as a one-off measure use regular unleaded
gasoline with an octane rating of 87 AKI/
91 RON. Be aware that your vehicle is not cer-
tified with regular unleaded gasoline with an
octane rating of 87 AKI/91 RON and that usage
of this fuel may reduce the engine's output and
increase fuel consumption. Avoid driving at full
throttle and sudden acceleration. Never refuel
using gasoline with a lower AKI/RON rating.
iIn some countries, the available gasoline
may not be sufficiently low in sulfur. This fuel can temporarily produce unpleasant odors,
especially on short journeys. The odors are
reduced as soon as sulfur-free fuel (sulfur
content < 10 ppm) is used again for refueling.
For more information about refueling
(
Ypage 134).
Fuel additives
!Operating the engine with subsequently
added fuel additives can cause engine dam-
age. Do not mix fuel additives with fuel. This
does not include additives for the removal and
prevention of deposits. Gasoline can only be
mixed with additives recommended by
Mercedes-Benz. Follow the instructions in the
product description. You can find further
information on recommended additives in any
Mercedes-Benz Commercial Van Center.
Mercedes-Benz recommends using brand-name
fuels with additives.
If you use fuels without these additives for a long
period of time, deposits can form. This primarily
forms on the inlet valve and in the combustion
chamber.
In some countries, the available fuel grade may
be inadequate. Residue could build up in the fuel
injection system as a result. In this case, in con-
sultation with a Mercedes-Benz Commercial
Van Center, the fuel should be mixed with the
cleaning additive recommended by Mercedes-
Benz. You must observe the notes and mixing
ratios indicated on the container. Do not add other fuel additives to the fuel. This
results in unnecessary costs and can damage
the engine.
Information on fuel consumption
HEnvironmental note
CO
2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO
2emissions are directly related to
fuel consumption and therefore depend on:
Refficient use of the fuel by the engine
Rdriving style
Rother non-technical factors, such as envi-
ronmental influences, road conditions or
traffic flow
You can minimize your vehicle's CO
2emis-
sions by driving carefully and having it serv-
iced regularly.
Only for certain countries: the respective cur-
rent consumption and emission values of your
vehicle can be found in the COC papers (EC
CERTIFICATE OF CONFORMITY). These docu-
ments are supplied when the vehicle is deliv-
ered.
Consumption figures were found in the currently
valid respective version:
Rfor vehicles with exhaust gas standard Euro 6
as per directive (EC) no. 715/2007
Rfor vehicles with exhaust gas standard EURO
VI as per directive (EC) no. 595/2009
Fuel consumption depends on:
Rthe vehicle version
Rthe style of driving
Rthe operating conditions
Rthe type or quality of the fuel used
The vehicle will use mor e fu
el than usual in the
following situations:
Rat very low outside temperatures
Rin city traffic
Rduring short journeys
Ron mountainous terrain
Rwhen towing a trailer
Observe the advice in the "Protection of the
environment" section to keep fuel consumption low (
Ypage 29).

on the cargo compartment floor if:
Rthe load is secured to two cargo tie-down
points on the rail and
Rthe distance to the nearest load-securing
point on the same rail is approximately 3 ft
(1 m)
Maximum roof load
GWARNING
If you use openings in the bodywork or
detachable parts as steps, you could:
Rslip and/or fall
Rdamage the vehicle and cause yourself to
fall.
There is a risk of injury.
Always use secure climbing aids, e.g. a suita-
ble ladder.
!Do not use the lower sliding door guide (car-
riage) as a step. Otherwise, you could damage
the paneling and/or the sliding door mecha-
nism.
GWARNING
When you load the roof, the center of gravity
of the vehicle rises and the driving character-
istics change. If you exceed the maximum roof
load, the driving characteristics, as well as
steering and braking, will be greatly impaired.
There is a risk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
!The weight of any load carried on the roof,
including the roof carrier, must not exceed
the maximum permissible roof load.
The roof carrier supports must be mounted at
equal distances.
Install rail carriers in front of and behind the
middle prop.
!For safety reasons, Mercedes-Benz recom-
mends that you only use roof carrier systems
which have been tested and approved for
Mercedes-Benz vehicles. This will help to
avoid damage.
Maximum roof load330 lbs (150 kg)
with at least three
pairs of support
points
The data is valid for a load distributed evenly
over the entire roof area.
Reduce the load on shorter roof carriers pro-
portionately. The maximum load per pair of roof
carrier supports is 110 lbs (50 kg). The maxi-
mum load of a rail carrier bar is 220 lbs (100 kg).
Loading guidelines and other information con-
cerning load distribution and load securing can
be found in the "Transporting" section
(
Ypage 244).
Trailer tow hitch
General notes
Mercedes-Benz recommends having a trailer
tow hitch retrofitted at an authorized Mercedes-
Benz Van Dealer.
Use only a trailer tow hitch that has been tested
and approved specially for your vehicle by the
distributor named on the inside of the front
cover. Only use a ball coupling for your Metris
trailer tow hitch if it has been approved for your
vehicle. You can also find information on the
permitted dimensions of the ball coupling on the
identification plate of the trailer tow hitch.
You can obtain advice from a qualified specialist
workshop. Also observe the information on tow-
ing a trailer in the "Driving and parking" section
(
Ypage 165).
