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" (
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.
Interchanging the front and rear wheels of
differing dimensions can render the general
operating permit invalid.
Observe the instructions and safety notes in
the "Fitting a wheel" section (
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 (
sure monitor (
page 438).

Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
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.

ahead position.
Vehicles with manual transmission:
depress the clutch pedal fully and engage

Vehicles with automatic transmission:
shift the transmission to position P.
Make sure that in vehicles with AIRMATIC,
the vehicle level is set to "Normal"
( page 234).

Vehicles without KEYLESS-GO: remove
the key from the ignition lock.
