General notes
With MOExtended tire s(tires with run fla tchar-
acteristics) ,you can continu etodrive your vehi-
cle eve nifthere is atotal loss of pressure in one
or more tires. The affected tire mus tnot show
any clearl yvisible damage.
You can recognize MOExtended tire sbythe
MOExtended marking which appears on the
sidewal lofthe tire .You will find this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index (
Ypage 330).
MOExtended tire smay only be used in conjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor.
If ap ressure loss warnin gmessage appears
in the multifunctio ndisplay:
Robserve the instructions in the display mes-
sages (Ypage 241).

XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of the

GWARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance. Damaged tires and atire
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is arisk of accident.

316Operation
Wheels and tires

Turn on ESP®and adapt your driving style
accordingly. When the outside temperature
falls below 10 †, use M+S tires.
iDifferent driving styles may lead to high tire
wear and the tires may reach the minimum
tire tread depth after only ashort time.
Regular checking of wheels and tires
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As aresult, you could lose control of
your vehicle. There is arisk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Check wheels and tires for damage at least once
am onth. Check wheels and tires after driving
off-road or on rough roads. Damaged wheels
can cause aloss of tire pressure. Pay particular
attention to damage such as:
Rcuts in the tires
Rpunctures
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width of
the tire (
Ypage 317). If necessary, turn the
front wheels to full lock in order to inspect the
inner side of the tire surface.
All wheels must have avalve cap to protec tthe
valve against dirt and moisture. Do not mount
anything ontot he valve other than the standard
valve cap or other valve caps approved by
Mercedes-Benz for your vehicle. Do not use any
other valve caps or systems, e.g. tire pressure
monitoring systems.
Regularly check the pressure of all the tires par-
ticularly prior to long trips. Adjust the tire pres-
sure as necessary (
Ypage 319).
The service life of tires depends, among other
things, on the following factors:
Rdriving style
Rtire pressure
Rdistance covered
Notes on tire tread
GWARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where speed is not adapted to suit the driving con-
ditions. There is arisk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
RSummer tires: âin (3 mm)
RM+S tires: ãin (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Marking :shows where the bar indicator
(arrow) for tread wear is integrated into the tire
tread.
Treadwear indicators (TWI) are required by law. Six indicators are positioned on the tire tread.
They are visible once atread depth of approx-
imately áin (1.6 mm) has been reached. If this
is the case, the tire is so worn that it must be
replaced.
Selecting, mounting and replacing
tires
ROnly mount tires and wheels of the same type
and make.

M+S tires
GWARNING
M+S tires with atire tread depth of less than

and do not provid esufficient traction. There is
ar isk of an accident.
M+S tires with atread depth of less than ãin

At temperatures belo w45‡ (+7 †), use winter
tires or all-season tires. Bot htype soft ire 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

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
