WARNING
Tyres, wheels or accessories whic hhaven ot
been approved by Mercedes-Ben zfor your
vehicle or are not used as they should be, can
impair driving safety. As aresult, you could
cause an accident .Before purchasing and
using them, enquire about their suitability,
legal stipulations and factory recommenda-
tion sataM ercedes-Benz Service Centre.
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva-
lidates the General Operatin gPermit for the
vehicle.
i Further information about tyres and
wheels can be obtained from any
Mercedes-Benz Service Centre. Operation
Notes on driving
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 atyre 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
examined at aqualified specialist work-
shop, e.g. aMercedes-Ben zService
Centre.
R When parkin gyour vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar eleva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tyres, particularly the
sidewalls, can get damaged. Notes on regularly inspecting wheels
and tyres
R Regularly chec kthe wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
cracksors evere corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause aloss 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 319). 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 avalve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitorings ystems) other than
the standard valve cap or other valve caps
approved by Mercedes-Ben zfor your vehi-
cle.
R Regularly check the pressure of all the tyres
including the emergenc yspare wheel or the
spare wheel, particularly prior to long trips,
and correc tthe pressure as necessary
(Y page 321). 318
OperationWheels and tyres

Tyre tread
G
WARNING
Bea rinm indt hat:
R tyr eg ripd ecreases rapidl yonwetroads
when the tread depth is less than 3mm.
Thus ,you should replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4mmorless as they no lon-
ger provide adequate grip.
R the tread on atyre 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 fron twheels to full lock in order to
inspect the tyre tread more easily.
Otherwise, you could lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road. 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. This also applies to
the emergency spare wheel/spare wheel. MOExtended tyres (tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics )allow you to continue driving the vehicle even when one or more tyres lose all
air pressure.
MOExtended tyres may only be used in con-
junction with the tyre pressure loss warning
system or with the tyre pressure monitor and
on wheels specifically tested by Mercedes-
Benz.
i
Vehicles with MOExtended tyres are not
equipped with aTIREFIT 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 properties, e.g. winter tyres. ATIREFIT
kit can be obtained from aMercedes-Benz
Service Centre.
You will find notes on driving with aflat tyre
in the "Breakdown assistance" section
(Y page 305). Winter operation
Please bear the following in mind
At the onset of winter ,have your vehicle win-
terproofed at aqualified specialist workshop,
e.g. at aMercedes-BenzS ervice Centre.
Observe the notes in the "Changing awheel"
section (Y page 323). Driving with summer tyres
At temperatures below +7 †, summer tyres
lose elasticit yand therefore traction and
brakin gpower; 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-Benzc annot accept responsibility
for this type of damage. M+S tyres
At temperatures below +7 †, use winter tyres
or all-season tyres. Bot htype soft yrea re
identified by th eM+S marking. Winter operation
319Wheels and tyres Z

Only winter tyres bearing the
isnowflake
symbol in addition to the M+S marking pro-
vide the best possibleg rip in wintry road con-
ditions. Only these tyres will allowd riving
safety systems such as ABS and ESP ®
to
function optimally in winter, as these tyres
have been designed specificallyf or driving on
snow.
Use M+S tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
WARNING
M+S tyres with atread depth of less than
4mmm ust be replaced. They are no longer
suitable for winter use and can no longer pro-
vide sufficient grip .This could cause you to
lose control of your vehicle and cause an acci-
dent.
Always observe the maximum permissible
speed specified for the M+S tyres you have
fitted.
If you fit M+S tyres which have alower max-
imum permissible speed than that of the vehi-
cle, affix an appropriate warning sign in the
driver's field of vision. This can be obtained
at aq ualified specialist workshop, e.g. at a
Mercedes-Ben zService Centre.
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 183).
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 321).
X Restart the tyre pressure loss warning sys-
tem (Y page 322). G
WARNING
If you fit the spare wheel when driving with M
+S tyres, bear in mind that driving stability will
be impaired due to unstable corneringc har-
acteristics caused by the different tyres. You
should therefore adapt your driving style and
drive carefully. Have the spare wheel replaced at the nearest
qualified specialist workshop which has the
necessary specialist knowledge and tools to
carry out the work required. Mercedes-Benz
recommends that you use
aMercedes-Benz
Service Centr efor this purpose. In particular,
work relevant to safety or on safety-related
systems must be carried out at aqualified
specialist workshop. Snow chains
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle
by Mercedes-Benz ,orthat are of acorre-
spondin gstandard of quality.
If you inten dtofit snow chains, please bear
the following point sinmind:
R it is not permissible to attac hsnow chains
to all wheel-tyre combinations; see the
information under "Wheel/tyre combina-
tions" in the "Wheels and tyres" section.
R snow chains must not be fitted to emer-
genc yspare wheels, e.g. a"Minispare"
emergency spare wheel.
R fit snow chains only in pairs and only to the
rear wheels. Observe the manufacturer's
installation instructions.
! Vehicles with steel wheels: if you wish
to fit snow chains to steel wheels, make
sure that you remove the respective
wheels' hubcaps first .The hubcaps may
otherwise be damaged.
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate ESP ®
(Y page 64) when pulling away with snow
chains fitted. This way you can allow the
wheels to spin in acontrolled manner, ach-
ieving an increased driving force (cutting
action). 320

Tyre pressure
Tyre pressure specifications
Yo uw illf ind atable of tyr epressures for var-
ious operating conditions on the insid eof
your vehicle's fuel fille rflap.
Operation with emergency spare wheel:
The applicable value for the emergency spare
wheel is stated on the spare wheel and in the
technical data section.
Operation with atrailer: The applicable
value for the rear tyre sisthe maximum tyre
pressure value stated on the table insid ethe
fuel filler flap.
The table insid ethe fuel filler flap may state
tyre pressures for differen tload conditions.
These are defined in the table as different
numbers of passengers and amounts of lug-
gage. The actual number of seats may vary –
for more information please refer to the vehi-
cle's registration documents.
If no other data is stated, the tyre pressures
specified on the fuel filler flap apply for all
tyres approved for this vehicle. If
at yre size precedes atyre pressure, the tyre
pressure information following is only valid
for that tyre size. Instead of the complete tyre size, the rim
diameter alone, for example
R16,may be lis-
ted. Rim diameter
:is part of the tyre size and
can be found on the tyre sidewall. G
WARNING
Tyre pressure that is either too high or too low
has anegative effect on the vehicle's driving
safety, which could lead you to cause an acci-
dent. Therefore, you should regularly check
the pressure of all the tyres, particularly prior
to long trips, and correc tthe pressure as nec-
essary.
To test tyre pressure, use asuitable pressure
gauge. The outer appearance of atyre does
not permit any reliablec onclusion about the
tyre pressure. G
WARNING
Do not fit anything else to the tyre valve other
than the standard valve cap. In particular, ret-
rofitted tyre pressure monitors which are
screwed on to the valve may overload it and
cause it to fail. Due to their design, the valve Tyrep
ressure
321Wheels and tyres
Z

is kept open continuously, which may lead to
air loss. G
WARNING
Should the tyre pressure drop repeatedly:
R chec kthe tyre for foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only avalve cap approved
by Mercedes-Ben zisfitted on the tyre
valve.
Tyre pressures that are too low have anega-
tive effect on vehicle safety, which could lead
you to cause an accident.
If possible, only correct tyre pressures when
the tyres are cold. The tyres are cold when
the vehicle has been parked for at least three
hours or has been driven less than 1.5 km.
Depending on the ambient temperature, the
speed you are driving at and the load on the
tyres, the tyre temperature and thus the tyre
pressure may change by approximately
10 kPa (0.1 bar/1.5 psi) per 10 †. Take this
into account when checking the pressure of
warm tyres and only correct it if it is too low
for the current operating conditions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have anegative effect on handling charac-
teristics and thus the driving safety (e.g. by
causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle. H
Environmental note
Check the tyre pressure regularly,atl east
every 14 days. Tyrep
ressur eloss warning system
Important safety notes While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in
atyre. If the speed
of rotation of awheel changes as aresult of
al oss of pressure, acorresponding warning
message will appearint he multifunction dis-
play. G
WARNING
The tyre pressure loss warning system does
not warn you of an incorrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you decide whether the tyre
pressures should be corrected.
The tyre pressure loss warning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detected by the tyre pressure loss
warning system.
The tyre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign object.
In the event of asudden loss of pressure, bring
the vehicle to ahalt by braking carefully. Do
not make any sudden steering movements
when doing so.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's
tyres.
R road conditionsa re wintry.
R you are driving on sand or gravel.
R you adopt avery sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you are towing avery heavy or large trailer.
R you are driving with aheavy load (in the
vehicle or on the roof). 322

if necessary, restart the tyre pressure loss
warning system or the tyre pressure monitor.
! On vehicles fitted with atyre pressure
monitor, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the tyres changed at aquali-
fied specialist workshop, e.g. aMercedes-
Benz Service Centre. Direction of rotation
Tyres with aspecified direction of rotation
have additional benefits, e.g. if there is arisk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed. An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
You may fit an emergency spare wheel/spare
wheel against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the emer-
gency spare wheel/spare wheel.
