Always pay attention to the instructions and
safety notes in the "Changing a wheel" section
( Y
page 312).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been approved
for Mercedes-Benz vehicles and the respective
wheel.
! Mercedes-AMG vehicles with ceramic-
brake disc: during removal and repositioning
of the wheel, the wheel rim can strike the
ceramic-brake disc and damage it. Therefore,
you should proceed carefully and get a sec-
ond person assist to you. Alternatively, you
can use a second alignment bolt.
! To prevent damage to the paintwork, hold
the wheel securely against the wheel hub
while screwing in the first wheel bolt.
X
Clean the wheel and wheel hub contact sur-
faces. X
Slide the wheel to be mounted onto the align-
ment bolt and push it on. X
Tighten the wheel bolts until they are finger-
tight. X
Unscrew the alignment bolt. X
Tighten the last wheel bolt until it is finger-
tight. X
Vehicles with a collapsible spare wheel:
inflate the collapsible spare wheel
( Y
page 319).
Only then lower the vehicle. Lowering the vehicle
G WARNING
The wheels could work loose if the wheel nuts
and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
! Vehicles with a collapsible spare wheel:
before lowering the vehicle, inflate the col-
lapsible spare wheel with the tire inflation
compressor. The wheel rim could otherwise
be damaged. X
Turn the crank of the jack counter-clockwise
until the vehicle is once again standing firmly
on the ground. X
Place the jack to one side.
X
Tighten the wheel bolts evenly in a crosswise
pattern in the sequence indicated ( C to
Vehicles with a tire pressure control sys-
tem: all installed wheels must be equipped with
functioning sensors.
Wheel and tire combinations You can ask for information regarding permitted
wheel-tire combinations at an authorized
Mercedes-Benz Center.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tires and wheels
which have been approved by Mercedes-Benz
specifically for your vehicle.
These tires have been specially adapted for
use with the control systems, such as ABS or
ESP ®
, and are marked as follows: R
MO = Mercedes-Benz Original R
MOE = Mercedes-Benz Original Extended
(tires featuring run-flat characteristics) R
MO1 = Mercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires may
only be used on wheels 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, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with a load, tire dimension variations
could cause the tires to come into contact
with the bodywork and axle components. This
could result 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.
Informati on o n tires, wheels and approved
combi
nations can be obtained from any quali-
fied specialist workshop.
! Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected on
retreaded tires. As a result, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tires are mounted. Do not mount used tires if
you have no information about their previous
usage. The recommended pressures for various oper-
ating conditions can be found: R
on the Tire and Loading Information placard
on the B-pillar on the driver's side R
in the tire pressure table in the fuel filler flap
Observe the notes on recommended tire pres-
sures under various operating conditions
( Y
page 295).
Check tire pressures regularly, and only when
the tires are cold. Comply with the maintenance
recommendations of the tire manufacturer in
the vehicle document wallet.
Notes on the vehicle equipment – always equip
the vehicle with: R
with tires of the same size on a given axle (left
and right) R
the same type of tires at a given time (summer
tires, winter tires, MOExtended tires)
Exception: it is permissible to install a differ-
ent type or make in the event of a flat tire.
Observe the "MOExtended tires (tires with
run-flat characteristics" section ( Y
page 278).
Vehi cles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory. It
is therefore recommended that you additionally
equip your vehicle with a TIREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. A TIREFIT kit may be obtained from
a qualified specialist workshop.
Emergency spare wheel
Important safety notes
G WARNING
The wheel or tire size as well as the tire type of
the spare wheel or emergency spare wheel
and the wheel to be replaced may differ.
Mounting an emergency spare wheel may
severely impair the driving characteristics.
There is a risk of an accident.
To avoid hazardous situations: R
adapt your driving style accordingly and
drive carefully. R
never mount more than one spare wheel or
emergency spare wheel that differs in size. R
only use a spare wheel or emergency spare
wheel of a different size briefly.Emergency spare wheel 317

Removing the collapsible spare wheel
(Mercedes-AMG vehicles)
The emergency spare wheel can be found in the
stowage well under the trunk floor. X
Lift the trunk floor upwards ( Y
page 247).X
Reach into cutout C in the tool holder and lift
it up. X
Remove collapsible spare wheel D .
Always observe the instructions and safety
notes in the "Mounting a wheel" section
( Y
page 313).
Stowing a used collapsible spare
wheel
! Only place the collapsible spare wheel in the
vehicle when it is dry. Otherwise, moisture
may get into the vehicle.
Take the following steps to stow a used collaps-
ible spare wheel. Otherwise, it will not fit into the
spare wheel well. Mercedes-Benz recommends
that you have this work performed at a qualified
specialist workshop, e.g. at an authorized
Mercedes-Benz Center. X
Unscrew the valve cap from the valve. X
Use the back of the valve cap to unscrew the
valve insert from the valve and release the air.
i Fully deflating the tires can take a few
minutes. X
Screw the valve insert back into the valve. X
Screw the valve cap back on. X
Remove the protective sheet from the vehicle
tool kit and pull it over the collapsible spare
wheel. X
Stow the collapsible spare wheel in the emer-
gency spare wheel well under the trunk. Inflating the collapsible spare wheel
! Inflate the collapsible spare wheel using the
tire inflation compressor before lowering the
vehicle. The wheel rim could otherwise be
damaged.
! Do not operate the tire inflation compressor
for longer than eight minutes at a time without
a break. It may otherwise overheat.
The tire inflation compressor can be operated
again once it has cooled down.
Comply with the manufacturer's safety instruc-
tions on the tire inflation compressor label and
on the tire sealant bottle. X
Mount the collapsible spare wheel as descri-
bed ( Y
page 313).
The collapsible spare wheel must be mounted
before it is inflated. X
Remove the tire inflation compressor from
the stowage space under the trunk floor
( Y
page 277).
