WARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the wheel bolts to come loose. As a result, you could
lose a wheel while driving. There is a risk of
accident.
Never oil or grease wheel bolts. In the event ofdamage to the threads, contact a qualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving. G
WARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
! To prevent damage to the paintwork, hold
the wheel securely against the wheel hub
while screwing in the first wheel bolt.
Always pay attention to the instructions and
safety notes in the "Changing a wheel" section
(Y page 372).
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.
! Always use wheel bolts
0044to mount the
"Minispare" emergency spare wheel. Using
other wheel bolts to mount the "Minispare"
emergency spare wheel could damage the
brake system. 0043

Changing a wheelWheels and tires

Lowering the vehicle
G
WARNING
The wheels could come loose if the wheel
bolts or wheel nuts are not tightened to the
prescribed tightening torque. There is a risk of an accident.
Ensure that the wheel bolts or wheel nuts are tightened to the prescribed tightening torque.
If you are not sure, do not move the vehicle.
Contact a qualified specialist workshop and
have the tightening torque checked immedi-
ately.
! Mercedes-AMG vehicles with a collapsi-
ble spare wheel: before lowering the vehicle,
inflate the collapsible spare wheel with the
tire inflation compressor. The wheel rim could
otherwise be damaged.
X Place the ratchet wrench onto the hexagon
nut of the jack so that the letters ABare visi-
ble.
X Turn the ratchet wrench 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 (0043 to0083).
The tightening torque must be 110 lb-ft
(150 Nm) .
X Turn the jack back to its initial position.
X Stow the jack and the rest of the tire-change
tool kit in the stowage well under the cargo
compartment floor again.
X Check the tire pressure of the newly mounted
wheel and adjust it if necessary.
Observe the recommended tire pressure
(Y page 355). When you are driving with the collapsible spare
wheel mounted, the tire pressure loss warning
system or the tire pressure monitor cannot func- tion reliably. Only restart the tire pressure loss
warning system or tire pressure monitor when
the defective wheel has been replaced with a
new wheel.
Vehicles with a tire pressure control sys-
tem: all installed wheels must be equipped with
functioning sensors. Wheel and tire combinations
Information regarding permitted wheel/tire
combinations can be found 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.
Information on tires, wheels and approved
combinations can be obtained from any quali-fied specialist workshop.
! Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz, since previ- Wheel and tire combinations

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 355).
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:
R with tires of the same size on a given axle (left
and right)
R with the same type of tires at a given time
(summer tires, winter tires, MOExtended
tires)
i Vehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the fac- tory. 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.
R do not switch ESP ®
off.
R have a spare wheel or emergency spare
wheel of a different size replaced at the
nearest qualified specialist workshop.
Observe that the wheel and tire dimensions
as well as the tire type must be correct.
! Mercedes-AMG vehicles with
"Minispare" emergency spare wheel: only
use the "Minispare" emergency spare wheel
on the rear axle. If you mount the
"Minispare" emergency spare wheel on the
front axle, this could result in damage to the
brake system.
If a tire on the front axle is defective, an intact
wheel from the rear axle must first be
replaced with the "Minispare" emergency
spare wheel. The damaged wheel on the front
axle can then be replaced by the undamaged wheel from the rear axle.
Make sure to note the placard on the
"Minispare" emergency spare wheel.
When using an emergency spare wheel or spare wheel of a different size, you must not exceed
the maximum speed of 50 mph (80 km/h).
You should regularly check the pressure of the
emergency spare wheel, particularly prior to
long trips, and correct the pressure as neces-
sary (Y page 355). The value on the wheel is
valid.
Snow chains must not be mounted on emer-
gency spare wheels. General notes
Information regarding permitted emergency
spare wheels can be found at an authorized
Mercedes-Benz Center.
Mounting the emergency spare wheel is descri- bed under "Mounting a wheel" (Y page 373).
An emergency spare wheel may also be moun-
ted against the direction of rotation. Observe 378
