The maximum driving distanc
eis
approximately 50 miles (80 km) when the
vehicle is partially laden and approximately
18 miles (30 km) when the vehicle is fully
laden.
In addition to the vehicle load, the driving
distanc epossible depends upon:
R Speed
R Road condition
R Outside temperature
The driving distanc epossible in run-flat mode
may be reduced by extreme driving
conditions/maneuvers, or it can be increased
through amoderate style of driving.
The maximum permissible distanc ewhich
can be driven in run-flat mode is counted from
the moment the tire pressure loss warning
appears in the multifunction display.
You must not exceed amaximum speed of
50 mph (80 km/h).
i When replacing one or all tires, make sure
that you use only tires:
R of the size specified for the vehicle and
R marked "MOExtended"
If at ire has gone flat and cannot be
replaced with aMOExtended tire, a
standard tire may be used as atemporary
measure. Make sure that you use the
proper size and type (summer or winter
tire).
i Vehicles equipped with MOExtended tires
are not equipped with aTIREFIT kit at the
factory. It is therefore recommended that
you additionally equip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
AT IREFIT kit can be obtained from a
qualified specialist workshop.

Exception: it is permissible to install a
different type or make in the event of aflat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics" section
(Y page2 95).
R Only mount tires of the correct size onto
the wheels.
R After mounting new tires, brea kthem in at
moderate speeds for the first 60 miles
(100 km), as they only reach their full
performance after this distance.
R Do not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
R Replace the tires after six years at the
latest, regardless of wear. MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is atotal loss of
pressure in one or more tires.
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system and only on wheels
specifically tested by Mercedes-Benz.
Notes on driving with MOExtended tires with
af lat tire (Y page 295). i
Vehicles equipped with MOExtended tires
are not equipped with aTIREFIT kit at the
factory. It is therefore recommended that
you additionallye quip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
AT IREFIT kit can be obtained from a
qualified specialist workshop. Winter operation
General notes
Have your vehicle winterproofed at aqualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing awheel"
section (Y page 336). Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your
vehicle to M+S tires. Using summe rtires at
very cold temperatures coul dcause cracks to
form, thereb ydamaging the tires
permanently. Mercedes-Benz cannot accept
responsibility for this type of damage. M+S tires
G
WARNING
M+S tires with atire tread depth of less than
0015 in (4 mm) are not suitabl efor 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 0015
in (4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †), use
winter tires or all-season tires. Both type sof
tire are identified by the M+S marking.
Only winter tires bearing the 000Esnowflake
symbol in addition to the M+S marking
provide the best possibl egrip in wintry road
conditions. Only these tires will allow driving 314
