Load index (example)
In addition to the load-bearing index, load rat-
ing:may be imprinted after the letters that
identify speed rating on the sidewall of the tire
(
Ypage 293).
RIf no specification is given: no text (as in the
example above), represents a standard load
(SL) tire
RRF or Reinforced: represents a reinforced tire.
Alternatively, depending on the manufac-
turer, the designation XL (Extra Load) can be
used.
RLight Load: represents a light load tire
RC, D, E: represents a load range that depends
on the maximum load that the tire can carry at
a certain pressure
iTire data is vehicle-specific and may deviate
from the data in the example.
Maximum tire load
Example: maximum tire load
Maximum tire load :is the maximum permis-
sible weight for which the tire is approved.
Do not overload the tires by exceeding the
specified load limit. The maximum permissible load can be found on the vehicle's Tire and
Loading Information placard on the B-pillar on
the driver's side (
Ypage 290).
iThe actual values for tires are specific to
each vehicle and may deviate from the values
in the illustration.
DOT, Tire Identification Number (TIN)
U.S. tire regulations stipulate that every tire
manufacturer or retreader must imprint a TIN in
or on the sidewall of each tire produced.
The TIN is a unique identification number. The
TIN enables the tire manufacturers or retreaders
to inform purchasers of recalls and other safety-
relevant matters. It makes it possible for the
purchaser to easily identify the affected tires.
The TIN is made up of manufacturer identifica-
tion code ;, tire size =, tire type code ?and
manufacturing date A.
DOT (Department of Transportation): tire
symbol :indicates that the tire complies with
the requirements of the U.S. Department of
Transportation.
Manufacturer identification code: manufac-
turer identification code ;provides details on
the tire manufacturer. New tires have a code
with two symbols. Retreaded tires have a code
with four symbols.
Further information about retreaded tires
(
Ypage 279).
Tire size: identifier=describes the tire size.
Tire type code: tire type code?can be used by
the manufacturer as a code to describe specific
characteristics of the tire.
Date of manufacture: date of manufactureA
provides information about the age of a tire. The first and second positions represent the week of
manufacture, starting with "01" for the first cal-
endar week. Positions three and four represent

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.
298Changing wheels
Wheels and tires

When using a wheel/spare wheel with a new or
newly painted wheel rim, have the wheel bolts/
nuts retightened again after approximately 600
to 3,000 miles (1,000 to 5,000 km). Observe the
specified tightening torque.

General notes
!
Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected on
retreaded tires. As a result, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tires are mounted. Do not mount used tires if you have no information about their previous
usage.
!For safety reasons, Mercedes-Benz recom-
mends that you only use tires, wheels and
accessories which have been specially
approved by Mercedes-Benz for your vehicle.
These tires have been specially adapted for
use with the driving safety systems, such as
ABS or ESP
®.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with a load, tire dimension variations
could cause the tires to come into contact
with the bodywork and axle components. This could result in damage to the tires or the vehi-
cle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tires, wheels or
accessories other than those tested and
approved.
Further information on wheels, tires and
approved combinations can be obtained from
any qualified specialist workshop.
!Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll comfort and suspension comfort are reduced and the
risk of damage to the wheels and tires as a
result of driving over obstacles increases.
You will find a table with the recommended tire
pressures for various vehicle loads on the inside
of your vehicle's fuel filler flap or under "Tire
pressure tables" (
Ypage 290). You can find fur-
ther information under "Tire pressure"
(
Ypage 282).
Check tire pressures regularly and only when
the tires are cold.
Notes on the vehicle equipment – always equip
the vehicle:
Rwith tires of the same size across an axle
(left/right)
Rwith the same type of tires on all wheels at a
given time (summer tires, winter tires)
iNot all wheel/tire combinations can be
installed at the factory in all countries.

Spare wheel
Important safety notes
GWARNING
Wheel and tire dimensions as well as the type of tire can vary between the spare wheel and
the wheel to be replaced. When the spare
wheel is mounted, driving characteristics may be severely affected. There is a risk of an acci-
dent.
In order to reduce risks:
Ryou should therefore adapt your driving
style and drive carefully.
Rnever mount more than one spare wheel
that differs from the wheel to be replaced.
Ronly use a spare wheel that differs from the
wheel to be replaced for a short time.
Rdo not deactivate ESP®.
Rhave a spare wheel that differs from the
wheel that has been changed replaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tire dimensions as well as the wheel type.
When using a spare wheel of a different size, do
not exceed the maximum permissible speed of
50 mph (80 km/h).
General notes
The procedure for mounting the spare wheel is
described in "Mounting a wheel" (Ypage 299).
The following should be checked regularly, par-
ticularly prior to long journeys:
Rthe tire pressure of the spare wheel, which
should then be corrected if necessary
(
Ypage 282)
Rthe fastenings of the spare wheel bracket
The spare wheel is located either in the left rear
compartment or in a spare wheel bracket under
the vehicle.
Replace the tires after six years at the latest,
regardless of wear. This also applies to the spare
wheel.
Vehicles with tire pressure monitor: the
spare wheel is not equipped with a sensor for
monitoring tire pressure. If you have installed a spare wheel, the tire pressure monitor will not
function for this wheel. The system may con-
tinue to show the tire pressure of the wheel that
has been removed for a few minutes. The value
displayed for the position where the spare wheel
is installed is not the same as the current tire
pressure of the spare wheel.
When you are driving with the spare wheel
mounted, the tire pressure monitor cannot func-
tion reliably. Only restart the tire pressure mon- itor when the defective wheel has been replaced
with a new wheel and sensor.
More Information can be found under "Tire pres-
sure monitor" (
Ypage 286).

The following components of the different vehi-
cle versions influence fuel consumption:
Rtire sizes, tire tread, tire pressure, tire condi-
tion
Rtransmission ratios for the drive assemblies
Radditional equipment (e.g. air-conditioning
system, auxiliary heating system)
For these reasons, the actual consumption fig-
ures for your vehicle may deviate from the con-
sumption figures determined according to EU

Engine oil
General notes
When handling engine oil, observe the important
safety notes on operating fluids (Ypage 306).
The quality of the engine oil used is of decisive
importance for the engine's functionality and
operating life. Mercedes-Benz continually
approves engine oils based on complex experi-
ments according to the current state of the art. Therefore, only Mercedes-Benz approved
engine oils may be used in Mercedes-Benz
engines. Mercedes-Benz recommends having
the oil changed at a qualified specialist work-
shop. Information about engine oils approved by
