Example
X Make sure that the base of the jack is posi-
tioned vertically under the jacking point.
X Turn crank Aclockwise until jack ?sits
completely on jacking point =and the
base of the jack lies evenly on the ground.
X Turn crank Auntil the tyre is raised a max-
imum of 3 cm off the ground.
Removing a wheel !
Do not place wheel bolts in sand or dirt.
The threads of the wheel bolts and wheel
hubs could otherwise be damaged when
the bolts are tightened. X
Unscrew the uppermost wheel bolt com-
pletely.
X Screw centring pin :into the thread
instead of the wheel bolt.
X Unscrew the remaining wheel bolts fully.
X Remove the wheel. Fitting a new wheel G
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 of damage 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.
Observe the instructions and safety notes on "Changing a wheel" (Y page 323).
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. X
Clean the wheel and wheel hub contact
surfaces.
X Slide the wheel to be mounted onto the
centring pin and push it on.
X Tighten the wheel bolts until they are fin-
ger-tight. Changing a wheel

gency spare wheel (Y page 335). 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. 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 vehicle
tools in the boot again.
X AMG vehicles and 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 318).
i If you are driving with the collapsible
emergency spare wheel fitted, the tyre
pressure loss warning system or the tyre
pressure monitor cannot function reliably.
Do not restart the tyre pressure loss warn- ing system/tyre pressure monitor until the
defective wheel has been replaced with a
new wheel.
Vehicles with a tyre pressure control
system: all fitted wheels must be equipped
with functioning sensors. 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. 328

Emergency spare wheel
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 318).
The applicable value is found on the wheel or
under "Technical data" (Y page 337).
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.
i If you are driving with the collapsible
emergency spare wheel fitted, the tyre
pressure loss warning system or the tyre
pressure monitor cannot function reliably.
Do not restart the tyre pressure loss warn-
ing system/tyre pressure monitor until the
defective wheel has been replaced with a
new wheel.
Vehicles with a tyre pressure monitor:
for a few minutes after an emergency spare wheel is fitted, the system may still display
the tyre pressure of the removed wheel.
The value displayed for the mounted emer-
gency spare wheel is not the same as the
current tyre pressure of the emergency
spare wheel. Removing the emergency spare wheel
(Example)
The collapsible emergency spare wheel can
be found in the stowage well under the boot
floor. X Lift and remove the reversible floor panel in
the boot (Y page 266).
X Turn retaining screw ;anti-clockwise and
remove it.
X Remove collapsible emergency spare
