MOExtended tires (tires with run-flat
characteristics) With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive you rv ehi-
cle even if there is at otal loss of pressure in one
or more tires.
MOExtended tires may only be use dinc onjunc-
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 ( Y
pag e2 47).
Vehicles equipped with MOExtended tires are
not equipped with aT IREFIT kit at the factory. It
is therefore recommende dt hat you additionally
equip you rv ehicl ew ith aT IREFIT kit if you mount
tires that do not feature run-fla tc haracteristics,
e.g. winter tires. AT IREFIT kit can be obtained
from aq ualified specialist workshop.
Winter operation
General notes Have you rv ehicl ew inter-proofed at aq ualified
specialist worksho patt he onset of winter.
Observe the notes in the "Changing aw heel"
section ( Y
pag e2 80).
Driving with summer tires At temperatures below 45 ‡( +7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on you rv ehicle
to M+S tires .U sing summe rt ires at very cold
temperatures coul dc aus ec racks to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage.
G WARNING
Damaged tires can caus et ire inflation pres-
sure loss. As ar esult, you coul dl ose control of
you rv ehicle. There is ar isk of accident.
Check the tires regularl yf or signs of damage
and replace any damaged tires immediately. M+S tires

To avoid hazardous situations: R
never install snow chains to the front
wheels R
alway si nstall 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 of ac orresponding
standard of quality. For more information,
please contact aq ualified specialist workshop.
If you inten dtom ount snow chains, please bear
the following points in mind: R
Snow chains may not be mounted on all
wheel/tire combinations. Permissible wheel-
tire combinations ( Y
page 284).R
Only use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come to ar oad that is not snow-covered.R
Local regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains. R
Do 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 ( Y
page 60).
You can thereby allow the wheels to spin in a
controlled manner ,a chieving an increased driv-
ing force (cutting action).

Important safety notes
G WARNING
Underinflated or overinflated tires pose the
following risks: R
the tires may burst, especially as the load
and vehicle speed increase. R
the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction. R
the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is ar isk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel: R
monthly, at least R
if the load changes R
before beginning al ong journeyR
under different operating conditions, e.g.
off-road driving
If necessary, correc tt he tire pressure.
