Some systems carry out a self-diagnosis when the ignition is switched on. Several warning and indicator lamps can thereby temporarily light up or flash. This behaviour is non-critical. These
warning and indicator lamps only indicate a malfunction if they light up or flash after the engine is started or during a journey. Wa

Preparing the vehicle
Your vehicle may be equipped with: R MOExtended tyres (tyres with run-flat char-
acteristics) (Y page 434)
Vehicle preparation is not necessary on
vehicles with MOExtended tyres.
R a TIREFIT kit (Y page 432)
R an emergency spare wheel (certain coun-
tries only) (Y page 474) Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It is
therefore recommended that you additionallyequip 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.
Vehicles with an Mercedes-Benz emergency
call system which are not equipped with a
TIREFIT kit: in the event of a flat tyre, contact
the Customer Assistance Centre for the
Mercedes-Benz emergency call system
(Y page 408).
Information on changing and fitting wheels
(Y page 463).
X Stop the vehicle as far away as possible
from traffic on solid, non-slippery and level
ground.
X Switch on the hazard warning lamps.
X Secure the vehicle against rolling away
(Y page 219).
X If possible, bring the front wheels into the
straight-ahead position.
X Switch off the engine.
X Remove the key from the ignition lock.
or, on vehicles with KEYLESS-GO start func-
tion or KEYLESS ‑GO:
X Open the driver's door.
The on-board electronics now have status
0. This is the same as the key having been
removed.
X Remove the Start/Stop button from the
ignition lock (Y page 187).
X Make sure that the passengers are not
endangered as they do so. Make sure that
no one is near the danger area while a
wheel is being changed. Anyone who is not
directly assisting in the wheel change
should, for example, stand behind the bar-
rier.
X Get out of the vehicle. Pay attention to traf-
fic conditions when doing so. Flat tyre
433Breakdown assis tance
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 (Y page 464).
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 (Y page 460) or the tyre pres-
sure monitor (Y page 462). 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 begained 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

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.
