Observe here the "MOExtended tyres (tyres
with run-flat characteristics)" section
(
page 388).
Y
Only fit tyres of the correct size onto the
R
wheels.
Run in new tyres at moderate speeds for the
R
first 100 km. They only reach their full per-
formance after this distance.
Do not drive with tyres which have too little
R
tread depth. This otherwise significantly
reduces the traction on wet roads (aquaplan-
ing).
Replace the tyres after six years at the latest,
R
regardless of wear.
Observe the notes on the emergency spare
wheel (
page 428).

MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat char-
acteristics), you can continue to drive your vehi-
cle even if there is a total loss of pressure in one
or more tyres.
MOExtended tyres may only be used in conjunc-
tion with an activated tyre pressure loss warning
system or with an activated tyre pressure mon-
itor and on wheels specifically tested by
Mercedes-Benz.
Notes on driving with MOExtended tyres with a
flat tyre (
page 388).
Y
i
Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It is
therefore recommended that you additionally
equip your vehicle with a TIREFIT kit if you fit
tyres that do not feature run-flat characteris-
tics, e.g. winter tyres. A TIREFIT kit can be
obtained from a qualified specialist work-
shop.
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 (
page 413).
Y
Winter operation
Driving with summer tyres
At temperatures below +7 †, summer tyres lose
elasticity and therefore traction and braking
power. Change the tyres on your vehicle 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.
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.
M+S tyres
G
WARNING
M+S tyres with a tyre tread depth of less than
4 mm are 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.
At temperatures below +7 †, use winter tyres or
all-season tyres. Both types of tyre are identified
by the M+S marking.
Only winter tyres bearing the i snowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions.
Only these tyres will allow driving safety sys-
tems such as ABS and ESP
mally in winter. These tyres have been devel-
oped specifically for driving in snow.
Use M+S tyres 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 tyres you have fit-
ted.
If you fit M+S tyres that have a lower maximum
permissible speed than that of the maximum
design speed of the vehicle, affix a correspond-
ing warning label in the driver's field of vision.
This can be obtained at a qualified specialist
workshop.
