MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive you rvehi-
cle even if there is atotal loss of pressure in one
or more tires.
MOExtended tires may only be use dinconjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor
and on wheels specifically tested by Mercedes-
Benz.
Notes on driving with MOExtended tires with a
flat tire (
Ypag e242).
Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory. It
is therefore recommendedt hat you additionally
equip you rvehicl ewithaTIREFIT kit if you mount
tires that do not feature run-fla tproperties, e.g.
winter tires. ATIREFIT kit can be obtained from
aq ualified specialist workshop.
Winter operation
General notes
Have you rvehicl ewinter-proofed at aqualified
specialist worksho patthe onset of winter.
Observe the notes in the "Changing awheel"
section (
Ypag e274).
Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on you rvehicle
to M+S tires .Using summe rtires at very cold
temperatures coul dcaus ecracks to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage.
GWARNING
Damaged tires can caus etire inflation pres-
sure loss. As aresult, you coul dlose control of
you rvehicle. There is arisk of accident.
Check the tires regularl yfor signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING
M+S tires with atire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
ar isk of an accident.
M+S tires with atread depth of less than ãin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †), use winter
tires or all-season tires. Both type softire are
identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking provide
the best possibl egrip in wintry road conditions.
Only these tires wil lallow driving safety systems
such as ABS and ESP
®to function optimally in
winter. Theset ires have beend eveloped specif-
ically for driving in snow.
Use M+S tires of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximu mpermissible
speeds pecified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
XCheck the tire pressures (Ypag e261).
XVehicles for Canada: restart the tire pres-
sure loss warning system (Ypag e262).
XRestart the tire pressure monitor
(Ypag e262).

To avoid hazardous situations:
Rnever install snow chains to the front
wheels
Ralwaysinstall snow chains in pairs to the
rear wheels.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have
been specially approved for your vehicle by
Mercedes-Benz,ora re ofacorresponding
standard of quality. For more information,
please contact aqualified specialist workshop.
If you inten dtomount snow chains, please bear
the following points in mind:
RSnow chains may not be mounted on all
wheel/tire combinations. Permissible wheel-
tire combinations (
Ypage 278).
ROnly use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come to aroad that is not snow-covered.
RLocal regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains.
RDo not exceed the maximum permissible
speed of 30 mph (50 km/h).
You may wish to deactivate ESP
®when pulling
away with snow chains installed (Ypage 58).
You can thereby allow the wheels to spin in a
controlled manner ,achieving an increased driv-
ing force (cutting action).

Important safety notes
GWARNING
Underinflated or overinflated tires pose the
following risks:
Rthe tires may burst, especially as the load
and vehicle speed increase.
Rthe tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
Rthe driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is arisk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-

Rbefore beginning along journey
Runder different operating conditions, e.g.
off-road driving
If necessary, correctt he tire pressure.
