Bar indicator : for tread wear is integrated
into the tire tread.
Selecting, mounting and replacing
tires
Only mount tires and wheels of the same
R
type and make.
Exception: it is permissible to install a
different type or make in the event of a flat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics" section
( page 441).
Y
Only mount tires of the correct size onto
R
the wheels.
Break in new tires at moderate speeds for
R
the first 60 miles (100 km). They only reach
their full performance after this distance.
Do not drive with tires which have too little
R
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
Replace the tires after six years at the
R
latest, regardless of wear. This also applies
to the spare wheel/emergency spare
wheel.
The service life of tires depends on the
following factors amongst other things:
Driving style
R
Tire pressure
R
Distance covered

MOExtended tires (tires with run-flat
properties)
MOExtended tires (tires with run-flat
properties) allow you to continue driving your
vehicle even if one or more tires are entirely
deflated.
MOExtended tires may be used only in
conjunction with the activated tire pressure
loss warning system or the activated tire
pressure monitor and only on wheels
specifically tested by Mercedes-Benz.
Notes on driving with MOExtended tires in the
event of a flat tire can be found in the
"Breakdown assistance" section
( page 441).

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 ( page 477).
Y
Driving with summer tires
At temperatures below 45 ‡ (+7 †), the
elasticity of summer tires and therefore also
the traction and braking capability are
reduced considerably. Mount M+S tires on
your vehicle. Using summer tires at very cold
temperatures could cause cracks to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility
for this type of damage.

M+S tires

At temperatures below 45 ‡ (+7 †), use
winter tires or all-season tires. Both types of
tire are identified by the M+S marking.
Only winter tires bearing the i snowflake
symbol in addition to the M+S marking
provide the best possible grip in wintry road
