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 emergency
spare wheel: Inflate the collapsible emer-
gency spare wheel using the tyre inflation
compressor before lowering the vehicle.
The rim could otherwise be damaged. X
Turn the crank of the jack anti-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 cross-
wise pattern in the sequence indicated ( :
to A). The specified tightening torque is
130 Nm.
X Turn the jack back to its initial position.
X Stow the jack and the rest of the tyre-
change tool kit in the boot again.
X Vehicles with AMG equipment: insert the
cover into the outer sill.
X Check the air pressure of the newly fitted
wheel and adjust accordingly.
Observe the recommended tyre pressure
(Y page 432).
If you are driving with the collapsible emer-
gency spare wheel fitted, the tyre pressure
loss warning system or the tyre pressure
monitor cannot function reliably. Only restart
the tyre pressure loss warning system/tyre
pressure monitor when the defective wheel
has been replaced with a new wheel.
Vehicles with a tyre pressure control sys-
tem: all fitted wheels must be equipped with
functioning sensors.
If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning
system cannot function reliably. Only restart
the tyre pressure loss warning system when
the defective wheel has been replaced with a
new wheel. Changing a wheel

Wheel and tyre combinations
General notes
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle.
These are specially adapted to the control
systems, such as ABS or ESP ®
and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with a load, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components. This could result in dam- age to the tyres or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tyres,
wheels or accessories other than those tes- ted and approved.
Further information about wheels, tyres
and approved combinations can be
obtained from any qualified specialist
workshop.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not fit
used tyres if you have no information about their previous usage. !
Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as a result of driving over obstacles
increases.
Overview of abbreviations used in the follow-
ing tyre tables:
R BA: both axles
R FA: front axle
R RA: rear axle
You will find a table with recommended tyre
pressures for various operating conditions on
the inside of your vehicle's fuel filler flap. For
further information on tyre pressure, see
(Y page 432). Check tyre pressures regularly
and only when the tyres are cold.
Notes on the vehicle equipment – always fit
the vehicle:
R with tyres of the same size on a given axle
(left/right)
R with the same type of tyres at a given time
(summer tyres, winter tyres, MOExtended
tyres)
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
Observe the "MOExtended tyres (tyres with
run-flat characteristics" section
(Y page 408).
Vehicles with MOExtended tyres 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 fit tyres that do not feature run-flat characteris-
tics, e.g. winter tyres. A TIREFIT kit can be
obtained from a qualified specialist work-
shop.
i Not all wheel/tyre combinations can be
fitted at the factory in all countries. 444

Important safety notes
G
WARNING
The wheel/tyre dimensions and the tyre type of the spare wheel/emergency spare wheel
and the wheel to be replaced may differ. Fit-
ting a spare wheel/emergency spare wheel
may severely impair the driving characteris-
tics. There is a risk of accident.
To prevent hazardous situations:
R Adapt your driving style accordingly and
drive carefully.
R Never fit more than one spare wheel/emer-
gency spare wheel if the dimensions are
different to those of the wheel being
replaced.
R Only use a spare wheel/emergency spare
wheel briefly if the dimensions are different to those of the wheel being replaced. R
Do not switch off ESP ®
.
R Have the spare wheel/emergency spare
wheel in question replaced at the nearest
qualified specialist workshop. Make sure
that the wheel/tyre dimensions and tyre
type are correct.
When using an emergency spare wheel or
spare wheel of a different size, you must not
exceed the maximum speed of 80 km/h.
Snow chains must not be fitted to emergency spare wheels. General notes
You should regularly check the pressure of all your tyres, including the emergency spare
wheel, particularly prior to long trips, and cor-
rect the pressure as necessary (Y page 432).
The value on the wheel is valid. In addition, the
emergency spare wheel tyre pressure can be found under "Technical data" (Y page 464).
2 Not in conjunction with AMG Line exterior package (code P31), suspension for greater ground clearance (code
482) and sports suspension (code 486).

An emergency spare wheel may also be fitted
against the direction of rotation. Observe the
time restriction on use as well as the speed
limitation specified on the emergency spare
wheel.
Replace the tyres after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
If you are driving with the collapsible emer-
gency spare wheel fitted, the tyre pressure
loss warning system or the tyre pressure
monitor cannot function reliably. Only restart the tyre pressure loss warning system/tyre
pressure monitor when the defective wheel
has been replaced with a new wheel.
Vehicles with tyre pressure monitor: after
mounting an emergency spare wheel, the sys- tem may still display the tyre pressure of the
removed wheel for a few minutes. The value
displayed for the mounted emergency spare
wheel is not the same as the current tyre
pressure of the emergency spare wheel.
If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning
system cannot function reliably. Only restart
the tyre pressure loss warning system when
the defective wheel has been replaced with a
new wheel. Removing the emergency spare wheel
The emergency spare wheel is secured in the
emergency spare wheel bag in the boot.
X Open the boot.
X Detach the fastening straps.
X Unhook retaining spring hooks of fastening
straps from the retainers.
X Remove the emergency spare wheel bag
with the emergency spare wheel.
X Open the bag and remove the emergency
spare wheel.
Observe the instructions and safety notes in
the "Fitting a wheel" section (Y page 438). Inflating the collapsible emergency
spare wheel
! Inflate the collapsible emergency spare
wheel using the tyre inflation compressor
before lowering the vehicle. The wheel rim
could otherwise be damaged.
! Do not operate the tyre inflation com-
pressor for longer than eight minutes at a
time without a break. It may otherwise
overheat.
The tyre inflation compressor can be oper-
ated again once it has cooled down. X
Mount the collapsible emergency spare
wheel as described (Y page 437).
The collapsible emergency spare wheel
must be mounted before it is inflated.
X Pull connector ?and the air hose out of
the housing.
X Remove the cap from the valve on the col-
lapsible emergency spare wheel.
X Screw union nut :of the air hose onto the
valve.
X Make sure on/off switch Aof the tyre
inflation compressor is set to 0.
X Insert plug ?into the cigarette lighter
socket or into a 12 V socket in your vehicle.
X Press the Start/Stop button once.
or X Turn the key to position 1in the ignition
lock. 462
