Secure the tow rope or tow bar to the tow-
ing eye or trailer tow hitch only. Otherwise,
the vehicle could become damaged.
! Do not use the towing eye for recovery,
this could damage the vehicle. If in doubt,
recover the vehicle with a crane.
! Drive slowly and smoothly when towing.
Excessive tractive power could otherwise
damage the vehicles.
! Shift the automatic transmission to posi-
tion i and do not open the driver's or front
passenger's door during towing. The auto-
matic transmission may otherwise shift to
position j, which could damage the trans-
mission.
! You may tow the vehicle for a maximum
distance of 30 miles (50 kilometers). A tow-
ing speed of
30 mph (50 km/h) must not be
exceeded.
For towing distances over 30 miles
(50 kilometers), the entire vehicle must be
raised and transported.
When towing away, you must observe the legal
requirements for the country in which you are
currently driving.
It is better to have the vehicle transported
than to have it towed.
Have the vehicle transported on a transporter
or trailer if it has transmission damage.
The automatic transmission must be in posi-
tion i when the vehicle is being towed away.
If the automatic transmission cannot be shif-
ted to position i, have the vehicle transpor-
ted on a transporter or trailer.
The battery must be connected and charged.
Otherwise, you:
R cannot turn the key to position 2 in the
ignition lock.
R cannot shift the transmission to position i.
Before the vehicle is towed, switch off the
automatic locking feature (Y page 76). You could otherwise lock yourself out of the vehi-
cle when pushing or towing away the vehicle. Installing/removing the towing eye
The fixture for the front towing eye is located in
the bumper. The rear towing eye is located under the bumper.
If you tow or tow-start a vehicle, attach the

R
Break in new tires at moderate speeds for
the first
65 miles (100 km).
R Do not drive with tires which have too little
tread depth, as this significantly reduces the
traction on wet roads (hydroplaning).
R Replace the tires after six years at the lat-
est, regardless of wear. This also applies to
the spare wheel. Operation in winter
General notes
Have your vehicle winterized at a qualified spe-
cialist workshop at the onset of winter.
Only use wheels with tire sizes approved for
Mercedes-Benz.
Prior to the onset of winter, ensure that snow
chains are stowed in the vehicle
(Y page
281). Snow chains cannot be moun-
ted on all wheel/tire combinations. Observe
the restrictions on the use of snow chains
under "Wheel/tire combinations"
(Y page 302).
Also observe the notes in the "Changing a
wheel" section ( Y page 297).Driving with summer tires
At temperatures below 45 ‡
(+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your vehi-
cle to M+S tires. Using summer tires at very
cold temperatures could cause tears to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility
for this type of damage. M+S tires
G
WARNING
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 charac-
teristics may be severely affected. There is a
risk of an accident. In order to reduce risks:
R you should therefore adapt your driving
style and drive carefully.
R never mount more than one spare wheel
that differs from the wheel to be replaced.
R only use a spare wheel that differs from
the wheel to be replaced for a short time.
R have 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. G
WARNING
M+S tires with a tire tread depth of less than
ã in
(4 mm) are not suitable for use in win-
ter and do not provide sufficient traction.
There is a risk of an accident.
M+S tires with a tread depth of less than ã
in (4 mm) must be replaced immediately.
Use winter tires or all-season tires at tempera-
tures below 45 ‡ (+7 †). Both types of tire
are identified by the M+S marking.
Only winter tires bearing the i snowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road condi-
tions.
Only these tires will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tires have been devel-
oped specifically for driving in snow.
For safe driving, use M+S tires of the same
make and tread pattern on all wheels.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
If you mount M+S tires that have a lower maxi-
mum permissible speed than the maximum
design speed of the vehicle, affix a corre-
sponding warning label in the driver's field of
vision. You can obtain this at a qualified spe-
cialist workshop.
Once you have mounted the winter tires:
X Check the tire pressure (Y page
282).
X Restart the tire pressure monitor
(Y page

Tire pressure table Tire pressure table inside the fuel filler flap
(example: Passenger Van)
Tire pressure table inside the fuel filler flap
(example: Cargo Van)
You will find the recommended tire pressure
for various operating conditions on the inside
of your vehicle's fuel filler flap
(Y page 137)
and under "Tire pressure table" (Y page 289).
If a tire size precedes a tire pressure, the fol-
lowing tire pressure information is only valid
for that tire size. Example: Cargo Van vehicle loads
Example: Passenger Van vehicle loads
:
Partially laden vehicle
; Fully laden vehicle
For the Passenger Van, the vehicle loads are
defined in the table as different numbers of
passengers and amounts of luggage. The
actual number of seats may vary – for more
information, please refer to the vehicle's regis-
tration documents.
The tire pressure value given for partly laden
vehicles are minimum values which offer you
good ride comfort. They are not for towing
trailers.
You can also use the tire pressure values for a
fully laden vehicle. These are always permitted
and admissible. However, in a partially laden
vehicle, the ride is not as comfortable and fuel
consumption is only minimally reduced. In
addition, wear is greater in the center of the
tire tread.
For towing trailers, the applicable value for the
rear tires is the maximum tire pressure value
stated in the table inside the fuel filler flap. Tire pressure

150 lb passengers in your vehicle, the
amount of available cargo and luggage
load capacity is
650 lbs. (1400 Ò 750 (5 x
150) = 650 lbs.).
(5) Determine the combined weight of lug- gage and cargo being loaded on the vehi-
cle. That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine
how this reduces the available cargo and
luggage load capacity of your vehicle.
The vehicle placard named in Step 1 is the Tire
and loading information placard for your vehi-
cle.
Please note that not all vehicles are approved
for trailer operation. Trailer operation is only
permitted when a trailer hitch is installed
(Y page
315). If in doubt, please consult a
qualified specialist workshop. Example: Steps 1 to 3
The following table shows examples of how to calculate total load and cargo capacities with vary-
ing seating configurations and number and size of occupants. The following examples use a max-
imum load of
1500 lbs (680 kg). This is for illustration purposes only. Make sure you are
using the actual load limit for your vehicle stated on your vehicle's Tire and Loading Information
placard . Example 1 Example 2 Example 3

You can find further information under: "Trailer tow hitch"
(Y page 315).Vehicle identification plate
Even if you have calculated the total load care-
fully, you should still make sure that the per-
missible gross weight and the gross axle
weight rating of your vehicle are not exceeded.
This data can be found on the vehicle identifi-
cation plate on the B-pillar of your vehicle
(Y page
304).
Gross Vehicle Weight Rating (GVWR): the
gross weight of the vehicle, all occupants, load
and trailer load/trailer tongue load (if applica-
ble) must not exceed the permissible gross
vehicle weight.
Gross Axle Weight Rating (GAWR): the maxi-
mum permissible load that can be carried by
one axle (front or rear axle).
To ensure that your vehicle does not exceed
the maximum permissible values (gross vehi-
cle weight and maximum gross axle weight rat-
ing), have your loaded vehicle (including driver,
occupants, load, and full trailer load if applica-
ble) weighed on a suitable vehicle weigh-
bridge. Trailer load/trailer tongue load
The trailer load/trailer tongue load affects the
gross weight of the vehicle. If a trailer is
attached, the trailer load/trailer tongue load is
included in the load along with occupants and
luggage. The trailer load/trailer tongue load is
usually approximately
10% of the gross weight
of the trailer and its load. What you should know about wheels

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 steel
wires in the bead to prevent the tire from com-
ing loose from the wheel rim.
SidewallThe 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 iden-
tify 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
capacity 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 á in (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 weightNominal load and goods/luggage load plus
68 kg (150 lbs) multiplied by the number of
seats in the vehicle. Changing wheels
Rotating the wheels
! 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"
(Y page
298).
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
available, 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 rotated. 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
hydroplaning. You will only gain these benefits
if the correct direction of rotation is observed. Changing wheels

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 previ-
ous usage.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tires, wheels and accessories which have been approved by
Mercedes-Benz specifically 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 var-
iations could cause the tires to come into
contact with the bodywork and axle compo-
nents. This could result in damage to the
tires or the vehicle.
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 a 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 com-
fort 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"
(Y page 289). You can
find further information under "Tire pressure"
( Y page 282).
Check tire pressures regularly and only when
the tires are cold.
Notes on the vehicle equipment – always
equip the vehicle:
R with tires of the same size across an axle
(left/right)
R with the same type of tires on all wheels at
a given time (summer tires, winter tires)
