Tyres and wheels
178 MOExtended run-flat system*
The MOExtended run-flat system allows you
to continue driving the vehicle even when one
or more tyres lose all air pressure.
The MOExtended run-flat system may only be
used in combination with the tyre pressure
loss warning system and only on wheels spe-
cifically tested and approved by Mercedes-
Benz.
i Vehicles with MOExtended run-flat sys-
tem are not equipped with the TIREFIT
kit* 24
.
Therefore, it is recommended that you
equip your vehicle additionally with the
TIREFIT kit* when fitting tyres that do not
feature run-flat properties, e.g. winter
tyres.
i A TIREFIT kit* is available from any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre.
You will find notes on driving with a flat tyre
in the "Practical advice" section
(Y page 262). Tyr
e tread G
Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3 mm.
Thus, you should replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4 mm or less as they will
no longer provide adequate grip.
R the tread on a tyre may not wear evenly.
Thus, you should regularly check the
tread depth and the condition of the
tread across the entire width of all tyres.
If necessary, turn the steering wheel so
that you can see the tyre tread more eas-
ily.
Otherwise, you could lose control of the
vehicle and cause an accident due to the
reduced grip of the tyres on the road. Tyre pressures
i You will find a table of tyre pressures for
various operating conditions on the inside
of your vehicle's fuel filler flap.
The valid value for the spare wheel* is sta-
ted on the spare wheel and in the technical
data section. G
Risk of accident
Tyre pressure that is either too high or too
low has a negative effect on the vehicle’s
driving safety, which could lead you to
cause an accident. Therefore, you should
regularly check the pressure of all your
tyres (including the spare tyre *), particu-
larly prior to long trips, and correct the
pressure as necessary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure. G
Risk of accident
Should the tyre pressure drop repeatedly:

Risk of accident
The ball coupling is only securely mounted
when the green mark on the handwheel is
aligned with the green area on the ball cou-
pling and the key can be removed. If the ball
coupling is not securely mounted, it may
come loose.
The ball coupling must be locked and the
key must be removed when towing a trailer.
This is the only way to guarantee that the
ball coupling is secured and cannot come
loose while the vehicle is in motion. If the
ball coupling cannot be locked and the key
cannot be removed, remove the ball cou-
pling and clean it. If the ball coupling can still not be fitted
(locked) after it has been cleaned, remove
the ball coupling. The trailer coupling must
then not be used to tow a trailer, as safe
operation is not guaranteed.
Have the entire trailer coupling checked at
a qualified specialist workshop. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
Notes on towing a trailer
G
Risk of accident
When reversing the vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
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: R
the permissible trailer drawbar nose-
weight
R the permissible trailer load
R the permissible rear axle load of the tow-
ing vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
You will find the applicable permissible val-
ues, which must not be exceeded, in the
vehicle documents.
You will find the values approved by the
manufacturer on the vehicle identification
plates and those for the towing vehicle in
the "Technical data" section.
You will find installation dimensions and loads
in the "Technical data" section
(Y page 290).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 75 kg.
However, the actual drawbar load must not
exceed the value given on the trailer coupling
and trailer identification plates. The lowest
weight applies.
! Use a noseweight as close as possible to
the maximum permissible noseweight. Do Operation

Genuine Mercedes-Benz parts
274 Introduction to technical data
i The technical data was determined in
accordance with EU directives. All data
applies to the vehicle's standard equip-
ment. The data may therefore differ for
vehicles with optional equipment. You can
obtain further information from a
Mercedes-Benz Service Centre. Genuine Mercedes-Benz parts
Mercedes-Benz tests genuine parts and con-
version parts and accessories which have
been specifically approved for your vehicle for
their reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to evaluate other parts. Therefore,
Mercedes-Benz accepts no responsibility for
the use of such parts in Mercedes-Benz vehi-
cles, even if they have been independently or
officially approved.
In Germany and some other countries, certain
parts are only officially approved for installa-
tion or modification if they comply with legal
requirements. All genuine Mercedes-Benz
parts meet this requirement. The use of non-
approved parts may invalidate the vehicle's
general operating permit. This is the case if:
R they cause a change of the vehicle type
from that for which the vehicle's general
operating permit was granted
R other road users could be endangered
R the emission or noise levels are adversely
affected
The use of non-approved parts could affect
your vehicle's operating safety. Therefore,
Mercedes-Benz recommends genuine Mercedes-Benz parts and conversion parts
and accessories that have been approved for
your vehicle. H
Environmental note
Daimler also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same
warranty applies as for new parts.
Genuine Mercedes-Benz parts and approved
conversion parts and accessories are availa-
ble from Mercedes-Benz Service Centres.
There, you can also receive advice about tech-
nical modifications and have the parts pro-
fessionally fitted.
Always quote the vehicle identification num-
ber and the engine number when ordering
genuine parts. For example, you will find
these numbers on your vehicle's identifica-
tion plates (Y page 276). Technical data

Tampering
with the engine electron-
ics G
Risk of accident
Only have work on the engine electronics
and related components carried out at a
qualified specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The vehicle's roadworthiness could other-
wise be affected.
! Only have work done on the engine elec-
tronics and its associated parts, such as
control units, sensors and connector leads,
carried out at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service
Centre. Otherwise, vehicle components
may wear more quickly and your vehicle's
warranty and operating permit may be inva-
lidated. Retrofitting electrical and electronic
equipment
Electrical and electronic equipment can jeop-
ardise the operating safety of your vehicle. If
equipment of this kind is retrofitted, it must
be type-approved and bear the emark. The
e mark may be obtained from the equipment
manufacturer or an authorised testing centre.
! Damage or consequential damage arising
from fitting equipment not approved by
Mercedes-Benz is not covered by the
Mercedes-Benz warranty.
If you wish to install two-way radios in the
vehicle, you must obtain formal approval.
Mercedes-Benz approves the installation of
two-way radios if such equipment is installed
professionally and a low-reflection exterior
aerial is used.
The transmission output of the two-way radio
must not exceed the maximum transmission
outputs listed. G
Risk of accident
Two-way radios may interfere with the vehi-
cle electronics and thereby jeopardise the
operational safety of the vehicle and your
own safety if: R
they do not have an exterior aerial
R the exterior aerial is not a low-reflection
aerial
R the exterior aerial has been fitted incor-
rectly G
Risk of injury
Excessive electromagnetic radiation may
also cause damage to your health and the
health of others. Using an exterior aerial
takes into account current scientific dis-
cussions relating to the possible health haz-
ards that may result from electromagnetic
fields.
For this reason, only have the exterior aerial
fitted at a qualified specialist workshop
which has the necessary specialist knowl-
edge and tools to carry out the work
required. Mercedes-Benz recommends
that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop.
