R MOExtended tyres (tyres with run-flat char-
acteristics) (Y page 276)
R a TIREFIT kit
R an emergency spare wheel (only for certain
countries)
You can find information on changing/fitting
wheels in the "Wheel change" section
(Y page 298).
i Vehicle preparation is no tnecessary on
vehicles with MOExtended tyres.
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit
if you fit tyres that do not feature run-flat
characteristics, e.g. winter tyres. A TIREFIT
kit can be obtained from a qualified spe-
cialist workshop.

WARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is a ris kofaccident.
Do not exceed the state dmaximum speed.
Avoid abrupt steering and driving manoeu-
vres, and driving ove robstacles (kerbs, pot-
holes, off-road). This applies in particular to a
laden vehicle.
Stop driving in emergency mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber.
R ESP ®
is intervening constantly.
R there are tears in the sidewalls of the tyre.
After driving in emergency mode, have the
wheel rims checked at a qualified specialist
workshop with regard to their further use. The
faulty tyre must be replaced.
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tyres.
MOExtended tyres may only be used in con-
junction with an activated tyre pressure loss
warning system.
The driving distance possible is 80 km when
the vehicle is partially laden, and 30 km when
the vehicle is fully laden. 276

i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.
i Please read the information on qualified

G
WARNING
If wheels and tyres of the wrong size are used,
the wheel brakes or suspensio ncomponents
may be damaged. There is arisk of accident.
Always replace wheels and tyres with those
that fulfil the specifications of the original part
(designation, manufacturer, model). G
WARNING
Af lat tyre severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of accident.
Tyres without run-flat characteristics:
R do not drive with aflat tyre.
R immediately replace the flat tyre with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop.
Tyres with run-flat characteristics:
R pay attention to the information and warn-
ing notices on MOExtended tyres (tyres
with run-flat characteristics).
Accessories that are not approved for your
vehicle by Mercedes-Ben zorare not being
used correctly can impair the operating
safety. Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and enquire about:
R suitability
R legal stipulations
R factory recommendations
Information on the dimensions and types of
wheels and tyres for yourv ehicle can be
found in the "Wheel/tyre combinations" sec-
tion (Y page 302).
Information on air pressure for the tyres on
your vehicle can be found:
R on the tyre pressure label on the fuel filler
flap
R in the "Tyre pressure" section
Modification work on the brake system and
wheels is not permitted. The use of wheel
spacers or brake dust shields is not permit-
ted. This invalidates the general operating
permit for the vehicle.
i Further information on wheels and tyres
can be obtained at any qualified specialist
workshop. Operation
Notes on driving
R Check the tyre pressures when the vehicle
is heavily laden and, if necessary, adjust.
R While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective,
reduce your speed immediately. Stop the
vehicle as soon as possible to chec kthe
wheels and tyres for damage. Hidden tyre
damage could also be causing the unusual
handling characteristics. If you find no
signs of damage, have the wheels and tyres
checked at a qualified specialist workshop.
R When parking your vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive 292
OperationWheels and tyres

over kerbs, speed humps or similar eleva-
tions, try to do so at an obtuse angle. Oth-
erwise, the tyres, particularly the sidewalls,
can get damaged. Notes on regularly inspecting wheels
and tyres G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control
of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damage
and replace any damaged tyres immediately.
R Regularly check the wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
cracks or severe corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure.
R Regularly check the tyre tread depth and
the condition of the tread across the whole
width of the tyre (Y page 293). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Benz for your vehi-
cle.
R You should therefore regularly check the
pressure of all your tyres, particularly prior
to long trips, and correc tthe pressure as
necessary (Y page 295).
Observe the notes on the emergency spare
wheel (Y page 304). The service life of tyres depends on various
factors, including the following:
R
driving style
R tyre pressure
R mileage Tyre tread
G
WARNING
Insufficient tyre tread will reduce tyre trac-
tion. The tyre is no longer able to dissipate
water. This means that on wet road surfaces,
the risk of aquaplaning increases, in particular
where speed is not adapted to suit the driving
conditions. There is a risk of accident.
If the tyre pressure is too high or too low, tyres
may exhibit different levels of wear at differ-
ent locations on the tyre tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
R summer tyres: 3 mm
R M+S tyres: 4 mm
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached.. Notes on selecting, fitting and replac-
ing tyres
R Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fittingn ew tyres, run them in at mod-
erate speeds for the first 100 km, as they
only reach their full performance after this
distance.
R Do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
R Replace the tyres after six years at the lat-
est, regardless of wear. Operation
293Wheels and tyres Z

Observe the notes on the emergency spare
wheel (Y
page 304). MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tyres.
MOExtended tyres may only be used in con-
junction with an activated tyre pressure loss
warning system and only on wheels specifi-
cally tested by Mercedes-Benz.
Notes on driving with MOExtended tyres in
the event of a flat tyre can be found in the
"Breakdown assistance" section
(Y page 276).
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with the TIREFIT
kit if you fit tyres that do not feature run-
flat characteristics, e.g. winter tyres. A
TIREFIT kit can be obtained from a qualified
specialist workshop. Winter operation
Points to remember
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 298). Driving with summer tyres
At temperatures below +7 †, summer tyres
lose elasticity and therefore traction and
braking power; change the tyres on your vehi-
cle to M+S tyres. Using summer tyres at very
cold temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility
for this type of damage. M+S tyres
G
WARNING
M+S tyres with a tyre tread depth of less than
4mma re not suitable for use in winter as they
do not provide sufficient traction. There is a
risk of accident.
M+S tyres with a tread depth of less than
4 mm must be replaced.
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 295).
X Restart the tyre pressure loss warning sys-
tem (Y page 296).
At temperatures below +7 †, use winter tyres
or all-seaso ntyres .Both types of tyre are
identified by the M+S marking.
Only winter tyres bearing the isnowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintry road con-
ditions. Only these tyres will allow driving
safety systems such as ABS and ESP ®
to
function optimally in winter, as these tyres
have been designed specifically for driving on
snow.
Use M+S tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics.
Always observe the maximum permissible
speed specified for the M+S tyres you have
fitted.
If you fit M+S tyres that have a lower maxi-
mum permissible speed than that of the vehi-
cle, affix an appropriate warning sign in the
driver's field of vision. This can be obtained in
a qualified specialist workshop.
Under these circumstances, you should also
restrict the maximum speed of the vehicle
using permanent SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres (Y page 154).294
