2011 MERCEDES-BENZ E-CLASS CABRIOLET winter tyres

warning system cannot function reliably.
Only restart th
etyrep ressure loss warning
system when the defective whee lhas been
replaced with anew wheel. MOExtended tyres (tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics) allow you to continue driving the
vehicl eeven when one or more tyres lose all
air pressure.
MOExtended tyres may only be usedinc on-
junction with the activated tyre pressure loss
warning system or with the tyre pressure
monitor.
The maximu mpermissible distanc ewhich
can be driven in run-flat mode depends on the
load in the vehicle. It is 80 km if the vehicle
is partially laden and 30 km if fully laden.
The maximum permissible distanc ewhich
can be driven in run-flat mode is counted from
the momen tthe tyre pressure loss warning
appears in the multifunction display.
You must not exceed amaximum speed of
80 km/h. G
WARNING
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well as driving over obstacles
(i.e. kerbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distance that can
be driven in run-flat mode depends to alarge
extentont he loads placed on the vehicle. It
can be shorter due to high speeds, aheavy
load, sudden changes in direction, the road
surface condition, outside temperature, etc., or further if you drive carefully and conserva-
tively.
Do not continue to drive in run-flat 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 run-flat mode, you must have
the wheel(s) checked for damage at aquali-
fied specialist workshop which has the nec-
essary specialist knowledge and tools to carry
out the work required. The faulty tyre must be
replaced in every case.
Mercedes-Ben zrecommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
i When replacing one or all tyres, make
sure that you only use tyres marked
MOExtended and of the specified size for
the vehicle.
i Vehicles with MOExtended tyres are not
equipped with aTIREFI Tkit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with aTIREFI Tkit
if you fit tyres that do not feature run-flat
properties, e.g. winter tyres. ATIREFI Tkit
can be obtained from aMercedes-Benz
Service Centre. Battery
Important safety notes
In order for the batter ytoachieve the maxi-
mum possible service life, it must alway sbe
sufficiently charged.
Have the batter ycharge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period. Battery

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

nc haracteristics, e.g. handling, vehicle
noise emissions or fuel consumption ,may
otherwise be adversely affected. In addi-
tion, when driving with aload, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components.T his could result in dam-
age to the tyres or the vehicle.
Mercedes-Ben zaccepts no liability for
damag eresulting from the us eoftyres,
wheel soraccessorie sothe rthan those tes-
ted and approved.
Further information about tyres, wheels
and approved combinations can be
obtained from any Mercedes-Ben zService
Centre.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As aresult,
Mercedes-Ben zcannot guarante evehicle
safety if retreade dtyres are fitted. Do not
fit used tyres if you have no information
about their previous usage.
! Large wheels :the lower the section width
for acertain 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
tyres as aresult of driving over obstacles
increases.
i You will find atable of tyre pressures on
the inside of your vehicle's fuel filler flap.
For further information on tyre pressure,
see (Y page 321).
i Notes on the vehicle equipment –always
fit the vehicle:
R with tyre softhe same size on agiven axle
(left/right)
R with the same type of tyre satagiven
tim e(summer tyres, winter tyres,
MOExtende dtyres) i
Vehicles with MOExtende dtyre sare not
equipped with aTIREFIT kit at the factory.
It is therefore recommende dthat you addi-
tionally equip your vehicle with aTIREFIT kit
if you fit tyre sthat do not feature run-flat
properties ,e.g. winter tyres. ATIREFIT kit
can be obtained fro maMercedes-Benz
Service Centre.
