Always install and secure the ball coupling asdescribed. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
Please observe the manufacturer's operating
instructions for the trailer coupling if a detach-
able trailer coupling is used.
Exceeding the maximum permissible nose-
weight may cause damage to the following:
Ryour vehicle
Rthe trailer
Rthe ball coupling
Rtrailer tow hitch
The vehicle/trailer combination could become
unstable.
If the noseweight used is lower than the mini-
mum permissible noseweight, the vehicle/
trailer combination could also become unstable.
To avoid hazardous situations:
Rmake sure to check the noseweight before
each journey
Ruse a drawbar noseweight as close as possi-
ble to the maximum noseweight
Rdo not exceed the maximum permissible
noseweight
Rdo not use a noseweight lower than the min-
imum permissible trailer drawbar noseweight
When backing up the vehicle towards the trailer,
make sure there is nobody between the trailer
and the vehicle.
The applicable permissible values, which must
not be exceeded, can be fou nd:
Rin your vehicle documents
Ron the type plate of the trailer tow hitch and
trailer
Ron the vehicle identification plate
Couple and uncouple the trailer carefully. If you
do not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
Make sure that the following values are not
exceeded:
Rthe permissible trailer drawbar noseweight
Rthe permissible trailer load
Rthe permissible rear axle load of the towing
vehicle
Rthe maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-
climbing capability
Rhas an increased braking distance
Ris affected more by strong crosswinds
Rdemands more sensitive steering
Rhas a larger turning radius
This could impair the handling characteristics.
Adapt your driving style accordingly. Maintain a
safe distance. Drive carefully.
When towing a trailer, always adjust your speed
to the current road and weather conditions. Do
not excee
d the maximum permissible speed for
your vehicle/trailer combination.
You will find the values approved by the manu-
facturer on the vehicle identification plates and
those for the towing vehicle in the "Technical
data" section (
Ypage 297).
General notes
RDo not exceed the legally prescribed maxi-
mum speed for vehicle/trailer combinations
in the relevant country.
This lowers the risk of an accident.
ROnly install an approved trailer coupling on
your vehicle.
Further information on availability and on
installation is available from any authorized
Mercedes-Benz Center.
RThe bumpers of your vehicle are not suitable
for installing detachable trailer couplings.
RDo not install hired trailer couplings or other
detachable trailer couplings on the bumpers
of your vehicle.
RIf you do not need the ball coupling, remove
the ball coupling from the ball coupling
recess. This reduces the risk of damage to the
ball coupling.
iCheck the tire pressures when towing a
trailer. You will find the values in the tire pres-
sure table in the fuel filler flap of the vehicle

GWarning
A flat tire severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of an accident.
do not drive with a flat tire. Immediately
replace the flat tire with your spare wheel, or
consult a qualified specialist workshop.
Contact an authorized Mercedes-Benz Center if
you require information on tested and recom-
mended wheels and tires for summer and winter
driving. Advice on purchasing and caring for
tires is also available there. Accessories that are not approved for your vehi-
cle by Mercedes-Benz or are not being used cor-
rectly can impair the operating safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and ask about:
Rsuitability
Rlegal stipulations
Rfactory recommendations
Information on the dimensions and types of
wheels and tires for your vehicle can be found in
the "Wheel/tire combinations" section
(
Ypage 284).

Operation
Notes on driving
If the vehicle is heavily loaded, check the tire
pressures and correct them if necessary.
When parking your vehicle, make sure that the
tires do not get deformed by the curb or other
obstacles. If it is necessary to drive over curbs,
speed humps or similar elevations, try to do so
slowly and at an obtuse angle. Otherwise, the
tires, particularly the sidewalls, may be dam-
aged.
Regular checking of wheels and tires
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
RRegularly check the wheels and tires of your
vehicle for damage at least once a month, as
well as after driving off-road or on rough
roads. Damage includes bulges and deforma-
tion on tires, cuts, punctures, cracks or
262Operation
Wheels and tires
Winter operation
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (
Ypage 281).
Driving with summer tires
At temperatures below 45 ‡ (+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your vehicle
to M+S tires. Using summer tires at very cold
temperatures could cause cracks to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage.
M+S tires
GWARNING
M+S tires with a tire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
a risk of an accident.
M+S tires with a tread depth of less than ãin
(4 mm) must be replaced immediately.
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.
Do not exceed a maximum speed of 50 mph
(80 km/h) if a spare wheel of a different size is
installed.
At temperatures below 45 ‡ (+7 †), use all-
season tires or winter tires. Both types of tire are
identified by the M+S marking.
Not all tires with the M+S marking provide the
driving characteristics of winter tires. In addition
to the M+S marking, winter tires also have the
i snowflake symbol on the tire wall. Tires
with this marking fulfill the requirements of the
Rubber Manufacturers Association (RMA) and
the Rubber Association of Canada (RAC) regard-
ing snow traction, and were specially developed
for driving on snow. Only these tires will allow
driving safety systems such as ABS and ESP
®to
function optimally in winter, since these tires
have been designed specifically for driving on
snow.
Use M+S tires of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
XCheck the tire pressures (Ypage 265).
XRestart the tire pressure monitor
(Ypage 270).
iYou can obtain information about winter
tires that have been approved by Mercedes-
Benz especially for your vehicle at any
Mercedes-Benz Service center.
iFor further information about tires, see
(Ypage 286).
Snow chains
GWARNING
If you drive too fast with snow chains moun-
ted, they may snap. As a result, you could
injure others and damage the vehicle. There is
a risk of an accident.

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, level control, a roof rack or a high-per-
formance battery, are not included in the curb

TIN (Tire Identification Number)
This is a unique identifier which can be used by
a tire manufacturer to identify tires, for example
for a product recall, and thus identify the pur-
chasers. The TIN is made up of the manufactur- er's identity code, tire size, tire type code and
the 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 (Tongue Weight Rating)
The TWR specifies the maximum permissible
weight that the ball coupling of the trailer tow
hitch can support.
Treadwear indicators
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.
Occupant distribution
The distribution of occupants in a vehicle at their
designated seating positions.
Total load limit
Nominal load and luggage load plus 150 lb
(68 kilograms) multiplied by the number of seats
in the vehicle.
Changing a wheel
Flat tire
The "Breakdown assistance" section
(Ypage 250) contains information and notes on
how to deal with a flat tire.
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.
Rotating front and rear wheels of differing
dimensions can render the general operating
permit invalid.
Always pay attention to the instructions and
safety notices in the section on "Changing a
wheel and mounting a spare wheel"
(
Ypage 282).
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 wheels 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 wheel rotation.
Clean the contact surfaces of the wheel and the brake disc thoroughly every time a wheel is rota-
