Specia ls ervice requirementsThe specified maintenance interval takes only
the normal operation of the vehicle into
account .U nder arduous operating condition so r
increased load on the vehicle, maintenance
work must be carried out more frequently, for
example: R
regular cit yd rivin gw ith frequent intermediate
stops R
if the vehicle is primarily used to travel short
distances R
use in mountainous terrain or on poor road
surfaces R
if the engin eiso ften left idling for long periods
Under these or similar conditions, have, for
example, the air filter, engin eo il and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must be
checked more often. Further information can be

MOExtended tires (tires with run-flat
properties)
General notes 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. The affected tire must not show
any clearly visible damage.
You can recognize aM OExtended tire by the
MOExtended marking which appears on the
sidewal loft he tire. You wil lf ind this marking
next to the tire size designation, the load-bear-
ing capacity and the spee di ndex ( Y
pag e2 75).
MOExtended tires may only be use dinc onjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor.
If ap ressure los sw arnin gm essag ea ppears
in the multifunction display: R
observe the instructions in the display mes-
sage s( Y
pag e1 96)R
check the tire for damage R
if driving on, observe the following notes
The driving distance possible in run-fla tm ode is
approximately 50 mile s( 80 km) when the vehi-
cle is partiall yl aden and approximately 19 miles
(30 km) when the vehicl eisf ull yl aden.
In addition to the vehicl el oad, the driving dis-
tance possible depends upon: R
vehicl es peedR
road condition R
outside temperature
The driving distance possible in run-fla tm ode
may be reduced by extreme driving conditions
or maneuvers, or it can be increased through a
moderate style of driving.
The driving distance possible in run-fla tm ode is
counted from the moment the tire pressure loss
warning appears in the multifunction display.
You must not exceed am aximu md esign speed
of 50 mph (80 km/h).
When replacing one or all tires, please observe
the following specifications for you rv ehicle's
tires: R
size R
type and R
the "MOExtended "m ark
If at ire has gone flat and cannot be replaced
with aM OExtended tire, as tandard tire may be
use dasat emporary mea su re. Make sure that you use the prope rs ize and type (summer or
winter tire).
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, for exam-
ple.
Important safety notes
G WARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is ar isk of an accident.
Do not exceed the stated maximu ms peed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, potholes,
off-road). This applie sinp articula rtoal aden

Tire pressure
Wheel sa nd tires

The tire pressure monitor has ay ellow warning
lamp in the instrument cluster for indicating
pressure loss or am alfunction. Whether the
warning lamp flashes or lights up indicates
whether at ire pressure is too low or the tire
pressure monitor is malfunctioning: R
if the warning lamp is lit continuously, the tire
pressure on one or more tires is significantly
too low. The tire pressure monitor is not mal-
functioning. R
if the warning lamp flashes for approximately
am inute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
In addition to the warning lamp, am essage
appears in the multifunction display .O bserve
the information on display messages
( Y
page 196).
It may take up to ten minutes for am alfunction
of the tire pressure monitor to be indicated. A
malfunction will be indicated by the tire pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
malfunction has been rectified, the tire pressure
warning lamp goes out after af ew minutes of
driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at ag as station with ap ressure gage. The
tire pressures shown by the on-board computer
refer to those measured at sea level. At high
altitudes, the tire pressure values indicated by a
pressure gage are higher than those shown by
the on-board computer. In this case, do not
reduce the tire pressures.
The operation of the tire pressure monitor can
be affected by interferenc ef rom radio transmit-
ting equipment (e.g. radio headphones, two-way
radios) that may be being operated in or near the
vehicle.
