Changing a wheel
Flat tyre
You can find information on what to do in the event of a flat tyre in the "Breakdown assis-
tance" section (Y page 352). Information on
driving with MOExtended tyres in the event of a flat tyre can be found under "Breakdown
assistance" (Y page 352).
Vehicles with an emergency spare wheel: in the event of a flat tyre, the emergency
spare wheel is fitted according to the descrip-
tion under "Fitting a wheel" (Y page 380). Interchanging the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
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
monitor, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Only have tyres changed at a qualified spe- cialist workshop. Changing a wheel
379Wheels and tyres Z
Interchanging the front and rear wheels of
differing dimensions can render the general
operating permit invalid.
Observe the instructions and safety notes in
the "Changing a wheel" section (Y page 379).
The wear patterns on the front and rear tyres differ depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size front and rear wheels, 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
warning 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 aquaplaning. These advantages can only be gained if the tyres are fitted corresponding to the direction 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:
depress the clutch pedal fully and engage
first or reverse gear.
X Vehicles with automatic transmission:
shift the automatic transmission to posi-
tion P.
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove
the key from the ignition lock.
X Vehicles with KEYLESS-GO start-func-
tion or KEYLESS-GO: open the driver's
door.
The on-board electronics now have status
0. This is the same as the key having been removed.
X Vehicles with KEYLESS-GO start-func-
tion or KEYLESS-GO: remove the Start/
Stop button from the ignition lock
(Y page 165).
X If included in the vehicle equipment,
remove the tyre-change tool kit from the
vehicle.
X Safeguard the vehicle against rolling away
(Y page 192).
i Apart from some country-specific var-
iants, vehicles are not equipped with tyre-
changing tools. 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 qualified specialist workshop.
Necessary tyre-changing tools may
include, for example:
R Jack
R Wheel chock
R Wheel wrench 380

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
Apart from some country-specific variants,
vehicles are not equipped with an emergency spare wheel. Emergency spare wheels are
specific to the vehicle. For more information
on which emergency spare wheels are
approved for your vehicle, consult a qualified
specialist workshop.
You should regularly check the pressure of
the emergency spare wheel, particularly prior to long trips, and correct the pressure as nec-
essary (Y page 374). The value on the wheel is
valid. In addition, the emergency spare wheel
tyre pressure can be found under "Technical
data" (Y page 398).
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.
7 Use of snow chains not permitted. Observe the notes in the "Snow chains" section.
8 Observe the notes on "Large wheels" in the "Wheel/tyre combinations" section. 396
