blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nent sd amaged in this way may fail unexpect-
edly .T here is ar isk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis component sr eplaced imme-
diately. ! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park your vehicle for al ong period of
time directly after cleaning, particularl ya fter
cleaning the wheel rim with wheel cleaner.
Wheel cleaner can lead to the increased cor-
rosion of the brake discs and pads. Therefore,
drive for af ew minutes after cleaning. By
heating up the brakes, the brake discs and
pads dry. The vehicle can then be parked for a
long period of time.

vents to clean the inside of the windows. Do
not touch the insides of the windows with
hard objects, e.g. an ice scraper or ring. There
is otherwise ar isk of damaging the windows.
! Clea nt he water drainage channels of the
windshiel da nd the rear window at regular
intervals. Deposits such as leaves, petals and
pollen may under certain circumstances pre-
vent water from draining away. This can lead
to corrosion damage and damage to elec-
tronic components. X
Clea nt he inside and outside of the windows

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

Stop driving in emergency mode if: R
you hea rb anging noises. R
the vehicl es tarts to shake. R
you see smoke and smell rubber. R
ESP ®
is intervening constantly. R
there are tears in the sidewalls of the tire.
After driving in emergency mode, have the
whee lr ims checked at aq ualified specialist
worksho pw ith regard to their further use .T he
defective tire must be replaced in every case.
TIREFIT kit
Important safety notes TIREFIT is at ire sealant.
You can use TIREFIT to seal puncture sofupt o
0.16 in (4 mm) ,p articularly those in the tire
tread. You can use TIREFIT at outside tempera-
tures dow nt o

G WARNING
In the following situations, the tire sealant is
unable to provid es ufficient breakdown assis-
tance, as it is unable to seal the tire properly: R
there are cuts or puncture sint he tire larger
than those mentioned above. R
the whee lr im is damaged.R
you have drive natv ery low tire pressures or
on af lat tire.
There is ar isk of an accident.
Do not drive the vehicle. Contact aq ualified
specialist workshop.
G WARNING
The tire sealant is harmfu la nd causes irrita-
tion. It must not come into contact with your
skin, eye sorc lothing or be swallowed .Don ot
inhal eT IREFIT fumes .K eep tire sealant away
from children. There is ar isk of injury.
If you come into contact with the tire sealant,
observe the following: R
Rinse off the tire sealant from you rs kin
immediatel yw ith water.R
If the tire sealant comes into contact with

has come into contact with tire sealant. R
If an allergic reactio no ccurs, seek medical
attention immediately.
! Do not operate the tire inflation compressor
for longer than eigh tm inutes at at ime without
ab reak. It may otherwise overheat.
The tire inflation compressor can be operated
again once it has coole dd own.
Comply with the manufacturer’s safety instruc-
tions on the sticker on the tire inflation com-
pressor. Using the TIREFIT kit X
Do not remove any foreig no bjects which have
penetrated the tire, e.g. screws or nails. X
Remove the tire sealant bottle, the accompa-
nying TIREFIT sticker and the tire inflation
compressor from the stowage wel lu nder-
neath the trunk floor ( Y

H Environmenta ln ote
Hav et he used tir es ealan tb ottle disposed of
professionally, e.g .ataq ualifie ds pecialist
workshop.
If tir ep ressure of 20 0k Pa (2.0 ba r/ 29 psi )h as
bee na chieved after am aximu mp eriod of ten
minutes: X
Switch off the tire inflation compressor. X
Unscrew the filler hose from the valve of the
faulty tire. X
Stow the tire sealant bottle and the tire infla-
tion compressor. X
Pull away immediately .X
Stop after driving for approximately ten
minutes and check the tire pressure with the
tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
G WARNING
If the required tire pressure is not reached
after driving for as hort period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is ar isk of accident.
Do not continue driving. Contact aq ualified
specialist workshop.
i In cases such as the one mentioned above,
contact an authorized Mercedes-Benz Cen-
ter. Or call 1-800-FOR-MERCede s( in the
USA) or 1-800-387-0100 (in Canada). X
Correct the tire pressure if it is still at least
130 kPa (1.3 bar/19 psi) .S ee the Tire and
Loading Information placard on the driver's
side B-pillar or the tire pressure tabl eint he
fuel filler fla pf or values.X
To increase the tire pressure: switch on the
tire inflation compressor. X
To reduce the tire pressure: depress pres-
sure release button C next to pressure
gauge D . X
When the tire pressure is correct, unscrew the
filler hose from the valve of the sealed tire. X
Screw the valve cap onto the tire valve of the
sealed tire.
X
To remove the tire sealant bottle from the tire
inflation compressor, press together the lock-
ing tabs on the yellow cap. X
Pul lt he tire sealant bottle out of the tire infla-
tion compressor.
The filler hose remains attache dtot he tire
sealant bottle. X
Drive to the nearest qualified specialist work-
