reduce your speed and stop the vehicle as
soon as possible to check the wheels and
tyres for damage. Hidden tyre damage
could also be causing the unusual handling
characteristics. If you find no signs of dam-
age, have the wheels and tyres examined
at a specialist workshop, for example at a
Mercedes-Benz Service Centre.
When parking your vehicle, make sure that
R
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar eleva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tyres, particularly the
sidewalls, can get damaged.
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.
i
You may fit a spare tyre* against the
direction of rotation.
MOExtended run-flat system*
The MOExtended run-flat system allows you
to continue driving the vehicle even when one
or more tyres lose all air pressure.
The MOExtended run-flat system may only be
used in conjunction with the tyre pressure
loss warning system or with the tyre pressure
monitor* and on wheels specifically tested by
Mercedes-Benz.
i
Vehicles with the MOExtended run-flat
system are not equipped with the TIREFIT
41
kit.
It is therefore recommended to additionally
equip your vehicle with the TIREFIT kit when
Only for certain countries.

fitting tyres that do not feature run-flat
properties, e.g. winter tyres.
i
A TIREFIT kit is available from any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre.
You will find notes on driving with a flat tyre
in the "Practical advice" section
(
page 409).

Tyre tread
G
Risk of accident
Bear in mind that:
tyre grip decreases rapidly on wet roads
R
when the tread depth is less than 3 mm.
Thus, you should replace tyres that have
insufficient tread.
winter tyres should be replaced when the
R
tread depth is 4 mm or less as they will no
longer provide adequate grip.
the tread on a tyre may not wear evenly.
R
Thus, you should regularly check the tread
depth and the condition of the tread across
the entire width of all tyres. If necessary,
turn the steering wheel so that you can see
the tyre tread more easily.
You could otherwise lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road.
Tyre pressures
i
You will find a table of tyre pressures for
various operating conditions on the inside
of your vehicle's fuel filler flap.
The applicable value for the spare
wheel*/"Minispare" emergency spare
wheel* is stated on the spare wheel and in
the technical data section.
