MOExtended tires( tires with run-flat
properties)
General notes
With MOExtended tire s(tires with run fla tchar-
acteristics) ,you can continu etodrive your vehi-
cle eve nifthere is atotal loss of pressure in one
or more tires. The affected tire mus tnot show
any clearl yvisible damage.
You can recognize MOExtended tire sbythe
MOExtended marking which appears on the
sidewal lofthe tire .You will find this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index (
Ypage 330).
MOExtended tire smay only be used in conjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor.
If ap ressure loss warnin gmessage appears
in the multifunctio ndisplay:
Robserve the instructions in the display mes-
sages (Ypage 241).
Rcheck the tire for damage.
Rif driving on, observe the following notes.
The driving distance possible in run-flat mod eis
approximately 50 miles (80 km )whent he vehi-
cle is partiall ylad en. Whe nthe vehicl eisfully
laden it is approximately 19 miles (30 km). In addition to the vehicl
eload, the driving dis-
tance possible depends upon:
Rvehicl espeed
Rroa dcondition
Routsid etemperature
The driving distance possible in run-flat mode
may be reduce dbyextremedriving conditions
or maneuvers, or it can be increased through a
moderate style of driving.
The driving distance possible in run-flat mod

warning appears in the multifunction display.
You mus tnot excee damaximum speed of

Vehicles equipped with MOExtended tire sare
not equipped with aTIREFIT kit at the factory. It
is therefore recommended that yo uaddit ionally
equip your vehicl ewithaT IREFIT kit if yo umount

Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed ataqualified spe-
cialist workshop.
Always observe the instructions and safety
notes in the "Mounting awheel" section
(
Ypage 336).
The wear pattern sonthe front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclear wear pattern
has formed on the tires. Frontt ires typically
wear more on the shoulders and the rear tires in the center.
On vehicles that have the same size front and
rear wheels, you can rotatet he wheels accord-
ing to the intervals in the tire manufacturer's
warranty book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3,000 to 6,000 miles (5,000 to
10,000k m).Earlier may be necessary, depend-
ing on the degree of tire wear. Do not change the
direction of wheel rotation.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time awheel is rota-
ted. Check the tire pressure and, if necessary,
restart the tire pressure loss warning system
(
Ypage 323) or the tire pressure monitor
(Ypage 325).
Direction of rotation
Tires with aspecified direction of rotation have
additional benefits ,e.g. if there is arisk of hydro-
planing. These advantages can only be gained if
the tires are installed corresponding to the
direction of rotation.
An arrow on the sidewall of the tire indicates its
correctd irection of rotation.
Storing wheels
Storewheels that are not being used in acool,
dry and preferably dark place. Protectt he tires
from oil, grease, gasoline and diesel.
Mounting awheel
Preparing the vehicle
XStop the vehicle on solid, non-slippery and
level ground.
XApply the electric parking brake manually.
XBring the front wheels into the straight-ahead position.
XShift the transmission to position P.
XMake sure that the vehicle level is set to "Nor-
mal" on vehicles with AIRMATIC(Ypage 172).
XSwitch off the engine.
XVehicles without KEYLESS-GO: remove the
SmartKey from the ignition lock.
XVehicles with KEYLESS-GO start-function
or KEYLESS-GO: open the driver's door.
The on-board electronics now have status 0.
This is the same as the SmartKey having been
removed.
XVehicles with KEYLESS-GO start-function
or KEYLESS-GO: remove the Start/Stop but-
ton from the ignition lock (
Ypage 131).
XMake sure that the engine cannot be started
via your smartphon e(Ypage 134).
XIf included in the vehicle equipment, remove
the tire-change tool kit from the vehicle.
XSafeguard the vehicle against rolling away.
Securing the vehicle to prevent it from
rolling away
If your vehicle is equipped with awheel chock,i t
can be found in the vehicle tool kit (Ypage 300).
The folding wheel chock is an additional safety
measure to prevent the vehicle from rolling
away,f or example when changing awheel.
