Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed ataqualified spe-
cialist workshop.
Observe the instructions and safety notes in the
"Changing awheel" section (
Ypage 307).
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 rotat ethe 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).D ependin gontire wear, this may
be required earlier. 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
(Canada only) or the tire pressure monitor (USA
only).
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 j.
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 vehicle electronics are now in position
u.T his is the same as “key removed”.
XVehicles with KEYLESS-GO start-function
or KEYLESS-GO: remove the Start/Stop but-
ton from the ignition lock (
Ypage 122).
XMake sure that the engine cannot be started
via your smartphon e(Ypage 83).
XIf included in the vehicle equipment, remove
the tire-change tool kit from the vehicle.
XSafeguard the vehicle against rolling away
(Ypage 141).
iApart from certain country-specific varia-
tions, the vehicles are not equipped with a
tire-change tool kit. Some tools for changing a
wheel are specific to the vehicle. For more

General notes
You can ask for information regarding permitted
wheel/tire combinations at an authorized
Mercedes-Benz Center.
You should regularl ycheck the pressure of the
emergency spare wheel, particularly priort o
long trips, and correct the pressure as neces-
sary (
Ypag e290). The valu eonthe wheel is
valid.
!For safety reasons, Mercedes-Benz recom-
mends that you only use tires and wheels
which have been approved by Mercedes-Benz
specifically for you rvehicle.
These tires have been speciall yadapted for
use with the control systems, such as ABS or
ESP
®,a nd are marked as follows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended
(tires featuring run-fla tcharacteristics)
RMO1 = Mercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires may
only be use donwheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehiclen oise
emissions or fuel consumption, may other-
wis ebea dversely affected .Inaddition, when
driving with aload, tire dimension variations
coul dcaus ethe tires to come into contact
with the bodywork and axle components. This
coul dresult in damage to the tires or the vehi-
cle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tires, wheels or
accessories other than those tested and
approved.
Informatio nontires, wheels and approved
combinations can be obtained from any quali-
fied specialist workshop.
!Retreaded tires are neither tested nor rec-
ommendedbyM ercedes-Benz, since previ-
ous damage cannot alway sbedetected on
retreaded tires. As aresult, Mercedes-Benz
cannot guarantee vehicles afety if retreaded
tires are mounted .Donot mount use dtires if
you have no information abo ut thei
r previous
usage. The recommendedp
ressures for various oper-
ating conditions can be found:

Observe the notes on recommendedt ire pres-
sure sunder various operating conditions
(
Ypag e290).
Check tire pressures regularly,a nd only when
the tires are cold. Comply with the maintenance
recommendations of the tire manufacturer in
the vehicled ocument wallet.
Notes on the vehiclee quipment–alway sequip
the vehicle:
Rwith tires of the same size on agivena xle (left
and right)
Rwith the same type of tire (summer tires,
MOExtended tires, winter tires)
Exception: it is permissible to instal ladiffer-
ent type or make in the event of aflat tire.
Observe the "MOExtended tires (tires with
run-fla tcharacteristics" section (
Ypag e271).
Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory.I t
is therefore recommendedt hat you additionally
equip you rvehiclew ithaTIREFIT kit if you mount
tires that do not feature run-fla tproperties, e.g.
winter tires. ATIREFIT kit may be obtained from
