the wheels or tyres have different dimensions.
The wheel brakes or suspension components may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with a tyre pressure mon-
itor, electronic components are located in the wheel.
Tyre-fitting tools should not be applied in thearea of the valve, as this could damage the
electronic components.
Only have tyres changed at a qualified spe-
cialist workshop.
Interchanging the front and rear wheels of dif-
fering dimensions can render the general oper-
ating permit invalid.
Observe the instructions and safety notes in the "Changing a wheel" section (Y page 342).
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear pat-
tern has formed on the tyres. Front tyres typi-
cally wear more on the shoulders, while rear
tyres wear more in the centre.
On vehicles that have front and rear wheels of
the same size, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is
interchanged. Check the tyre pressure and, if
necessary, restart the tyre pressure loss warn-
ing system or the tyre pressure monitor. Direction of rotation
Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aqua-
planing. These advantages can only be gained if the tyres are fitted corresponding to the direc-
tion of rotation.
An arrow on the sidewall of the tyre indicates its correct direction of rotation. Storing wheels
Store wheels in a cool, dry and preferably dark
place if they are not being used. Protect the
tyres against oil, grease, petrol and diesel. Fitting a wheel
Preparing the vehicle X
Stop the vehicle on solid, non-slippery and
level ground.
X Apply the electric parking brake manually.
X Move the front wheels to the straight-ahead
position.
X Vehicles with manual transmission: fully
depress the clutch pedal and engage first or
reverse gear.
X Vehicles with automatic transmission:
shift the transmission to position
j.
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove the
key from the ignition lock.
X Vehicles with KEYLESS-GO start-function
or KEYLESS-GO: open the driver's door.
The vehicle electronics are now in position
u. This is the same as “key removed”.
X Vehicles with KEYLESS-GO start function
or KEYLESS-GO: remove the Start/Stop but-
ton from the ignition lock (Y page 144).
X If included in the vehicle equipment, remove
the tyre-change tool kit from the vehicle.
X Additionally secure the vehicle against rolling
away (Y page 166).
i Apart from some country-specific variants,
vehicles are not equipped with a tyre-change
tool kit. Some tools for changing a wheel are
specific to the vehicle. For more information
on which tools are required to perform a
wheel change on your vehicle, consult a quali-
fied specialist workshop.
Necessary tyre-changing tools may include,
for example:

Important safety notes

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 vehicle's maximum design speed of
80 km/h.
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 337).
The value on the wheel is valid.
Snow chains must not be fitted to emergency
spare wheels. General notes
You can ask for information regarding permitted emergency spare wheels at a Mercedes-Benz
Service Centre.
An emergency spare wheel may also be fitted
against the direction of rotation. Observe the
time restriction on use as well as the speed lim- itation 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 emergency spare
wheel fitted, the tyre pressure loss warning sys-
tem or the tyre pressure monitor cannot func-
tion reliably. Restart the tyre pressure loss warn- ing system or tyre pressure monitor only once
the defective wheel has been replaced with a
new wheel.
Vehicles with tyre pressure monitor: after an
emergency spare wheel has been fitted, the sys-
tem may still display the tyre pressure of the
removed wheel for a few minutes. The value dis- played for the position where the emergency
spare wheel is fitted is not the same as the cur- rent tyre pressure of the emergency spare
wheel. Removing the emergency spare wheel
Vehicles with the "Minispare" emergency spare
wheel:
The "Minispare" emergency spare wheel is
secured in emergency spare wheel bag :in the
luggage compartment.
X Open the tailgate.
X Release securing straps ;on emergency
spare wheel bag :.348
