or
X Depending on the size of the wheel, you
ma yalso be able to secure the faulty wheel
in the emergenc yspare wheel well. In this
case, you must remove the stowage tray
from the emergency spare wheel well and
store it securely in the luggage compart-
ment.
i When you are driving with the collapsible
emergency spare wheel fitted, the tyre
pressur eloss warnin gsystem or the tyre
pressure monitor cannot function reliably.
Only restart the tyre pressure los swarning
system/tyre pressure monitor when the
defective wheel has been replaced with a
new wheel.
Vehicles with tyre pressure monitor: all fit-
ted wheels must be equipped with func-
tioning sensors. The defective wheel
should no longer be in the vehicle. MOExtended tyres (tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics) allow you to continue driving the
vehicle even when one or more tyres lose all
air pressure.
MOExtended tyres may only be used in con-
junction with the activated tyre pressure loss
warning system or with the tyre pressure
monitor.
The maximum permissible distance which
can be driven in run-flat mode depends on the
load in the vehicle. It is 80 km if the vehicle
is partially laden and 30 km if fully laden.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tyre pressure loss warning
appears in the multifunction displ ay.
Yo um ust not exceed amaximum spee dof
80 km/h. G
WARNING
Th eh andling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well as driving over obstacles
(i.e. kerbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distance that can
be driven in run-flat mode depends to alarge
exten tonthe loads placed on the vehicle. It
can be shorter due to high speeds, aheavy
load, sudden changes in direction, the road
surface condition, outside temperature, etc.,
or further if you driv ecarefully and conserva-
tively.
Do not continue to drive in run-flat mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber.
R ESP ®
is intervening constantly.
R there are tears in the sidewalls of the tyre.
After driving in run-flat mode, you must have
the wheel(s) checked for damage at aquali-
fied specialist workshop which has the nec-
essary specialist knowledg eand tool stocarry
out the work required. The faulty tyre must be
replaced in every case.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose. In particular ,work relevant to safet yor
on safety-related system smust be carried out
at aq ualified specialist workshop.
i Whe nreplacing one or all tyres, make
sure that you only use tyres marked
MOExtended and of the specified size for
the vehicle.
i Vehicles with MOExtended tyres are not
equipped with aTIREFIT kit at th efactory. 342

Tyre tread
G
WARNING
Bea rinm ind that:
R tyre gri pdecrease srapidly on wetroads
when the tread depth is less than 3mm.
Thus ,you should repl acet yres that have
insufficient tread.
R winter tyres sho uld bereplaced when the
trea ddepth is 4mmorl ess as they no lon-
ger provide adequat egrip.
R thet rea donat yre may not wear evenly.
Thus ,you should regularly chec kthe tread
depth and the condition of the tread across
the entire widt hofall tyres. If necessary,
turn the fron twheels to full lock in order to
inspec tthe tyr etrea dm ore easily.
Otherwise, you coul dlose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road. Note
sons electing, fitting and replac-
ing tyres
R Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fittin gnew tyres, run them in at mod-
erat espeeds for the first 10 0km, as they
onl yreach their ful lperformanc eafter this
distance.
R Do not drive wit htyres which have too little
tread depth ,asthis significantly reduces
the traction on wet roads (aquaplaning).
R Replace the tyres after six year satthe lat-
est, regardless of wear .This also applies to
the emergency spar ewheel/spar ewheel. MOExtended ty
res( tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics) allo wyou to continue drivin gthe vehicle even when one or mor
etyres los eall
air pressure.
MOExtended tyres may only be used in con-
junction with the tyre pressure loss warning
system or with the tyre pressure monitor and
on wheels specifically tested by Mercedes-
Benz.
i Vehicles with MOExtended tyres are not
equipped with aTIREFIT kit at th efactory.
It is therefore recommended that you addi-
tionally equip your vehicle with the TIREFIT
kit if you fit tyres that do not feature run-
flat properties, e.g. winter tyres. ATIREFIT
kit can be obtaine dfrom aMercedes-Benz
Ser vice Centre.
Notes on driving with MOExtended tyres in
the event of aflat tyre can be found in the
"Breakdown assistance" section
(Y page 342). Winter operation
Points to remember
At the onset of winter ,have your vehicle win-
terproofed at aqualified specialist workshop,
e.g. at aMercedes-Ben zService Cent re.
Observe the notes in the "Changin gawheel"
section (Y page 363). Drivin
gwith summer ty res
At temperatures below +7 †, summer tyres
los ee lasticit yand therefore traction and
braking power; chang ethe tyres on your vehi-
cle to M+S tyres .Using summer tyres at very
cold temperatures could cause tears to form,
thereby damagin gthe tyres permanently.
Mercedes-Ben zcannot accept responsibility
for this type of damage. Winter operation

swith the AIRMATIC package, you
must drive at raised vehicle level if snow
chains have been fitted (Y page 188).
Do not exceed the maximum permissible
speed of 50 km/h.

Tyre pressure specifications
You wil lfind atable of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
Operation with emergency spare wheel:
the applicable value for the emergency spare
wheel is stated on the spare wheel and in the
technical data section.
Operation with atrailer: the applicable
value for the rear tyres is the maximum tyre
pressure value stated on the table insid ethe
fuel filler flap.
The tabl einsid ethe fuel filler fla pmay state
tyre pressures for different load conditions.
Thes eare define dinthe tabl easdifferent
number sofpassengers and amounts of lug-
gage. The actual number of seats may vary –
for more information, please refer to the vehi-
cle's registration documents.
If no other data is stated, the tyre pressures
specified on the fuel filler flap appl yfor all
tyres approved for this vehicle. If
at yre size precede satyre pressure, the tyre
pressure information following is only valid
for that tyre size. G
WARNING
Tyre pressure that is eithe rtoo high or too low
has anegativ eeffect on the vehicle's driving
safety ,which coul dlead you to cause an acci-
dent. Therefore, you should regularly check
the pressur eofall the tyres, particularly prior
to long trips, and correct the pressure as nec-
essary.
To test tyre pressure, use asuitabl epressure
gaug e. Th eouter appearance of atyre does
not permit any reliabl econclusion about the
tyr ep ressure. On vehicles fitted wit hthe elec-
tronic tyr epressure monitor, th etyre pres-
sure can be checked using the on-board com-
puter. G
WARNING
Do not fit anything else to the tyre valve other
than the standard valve cap. In particular, ret-
rofitted tyre pressure monitors which are
screwed on to the valve may overload it and
cause it to fail. Due to their design, the valve
is kept open continuousl y, whichmay lead to
air loss. Tyr

Tyres with aspecified direction of rotation
have additional benefits, e.g. if there is arisk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
You may fit an emergenc yspare wheel/spare
