Notes on regularly inspecting wheels
and tyres R
Regularly check the wheels and tyres of
your
vehicle for damage (e.g. cuts, punctu-
res, tears, bumps on tyres and deforma-
tion, cracks or severe corrosion on wheels),
at least every 14 days, as well as after off-
road trips or after travelling on rough roads.
Damaged wheels could cause a loss of tyre
pressure.
R Regularly check the tyre tread depth and
the condition of the tread across the whole
width of the tyre (Y page 200). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R All wheels must have a valve cap to protect
the valve against dirt and moisture.
R Regularly check the pressure of all your
tyres (including the spare tyre*), particu-
larly prior to long trips, and correct the
pressure as necessary ( Y page 200).
Notes on driving R
While driving, pay attention to vibrations,
noises and unusual handling characteris- tics, e.g. pulling to one side. This may indi-
cate

that the wheels or tyres are damaged.
If you suspect that a tyre is defective,
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 inspected
at a specialist workshop, for example at a
Mercedes-Benz Service Centre.
R When parking your vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar, try to
do so slowly and at an obtuse angle. Oth-
erwise, the tyres, particularly the sidewalls,
could get damaged. Direction of rotation
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 the tyre pressure
monitor* and on wheels specifically tested by
Mercedes-Benz.
i Vehicles with MOExtended run-flat sys-
tem are not equipped with the TIREFIT
kit* 25

Tyres and wheels
200It is therefore recommended to additionally
equip your vehicle with the TIREFIT kit*
when 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
(Y page 287). Tyre tread
G
Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when

the tread depth is less than 3 mm.
You should thus replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4 mm or less because oth-
erwise they no longer provide adequate
grip.
R the tread on a tyre may not wear evenly.
You should thus regularly check the tread
depth and the condition of the tread across the entire width of all tyres. If nec-
essary, turn the steering wheel so that
you can see the tyre tread more easily.
You could otherwise lose control of the
vehicle and cause an accident due to the
reduced grip of the tyres on the road. Tyre pressures
G
Risk of accident
Tyre pressure that is either too high or too
low has a negative effect on the vehicle’s
active

safety, which could lead you to cause
an accident. You should therefore regularly
check the pressure of all your tyres (includ-
ing the spare tyre*), particularly prior to
long trips, and correct the pressure as nec-
essary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure. On vehicles fitted with the elec-
tronic tyre pressure monitor*, the tyre pres-
sure can be checked in the on-board com-
puter.
If the vehicle is to be heavily laden or driven
at high speeds, the tyre pressure must be adapted according to the specifications given
in the fuel filler flap

(Y page 190).
Use the highest specified tyre pressure for
the spare wheel*. G
Risk of accident
Should the tyre pressure drop repeatedly:
R Check the tyre for foreign bodies.
R Check whether the wheel is losing air or
the valve is leaking.
Tyre

pressure that is too low has a negative
effect on the vehicle’s active safety, which
could lead to your causing an accident.
Tyre pressure changes by approximately
0.1 bar for every 10 °C change in ambient
temperature.
If you measure the tyre pressure in enclosed
spaces where the temperature differs from
the outside temperature, you will have to cor-
rect the measured value accordingly.
When the vehicle is driven, the tyre tempera-
ture, and with it the tyre pressure, will
increase depending on the road speed and
the load on the tyres.
Therefore, you should only correct tyre pres-
sures when the tyres are cold. Operation

287MOExtended run-flat system*
The MOExtended run-flat system must only
be
used in conjunction with the tyre pressure
loss warning system or the tyre pressure
monitor*.
! The maximum permissible distance which
can be driven in run-flat mode depends on
the load in the vehicle. It is 50 km if the
vehicle is partially laden and 30 km if fully
laden.
The maximum range that can be driven in
emergency operation is measured from the
point at which the pressure loss warning
message appears in the multi-function dis-
play.
You must not exceed a maximum speed of
80 km/h.
i Vehicles featuring the MOExtended run-
flat system are not equipped with the
TIREFIT kit*.
It is therefore recommended to additionally
equip your vehicle with the TIREFIT kit*
when 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. G
Risk of accident
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and
avoid

sudden changes in direction and sud-
den acceleration, as well as driving over
obstacles (i.e. kerbs, potholes), and driving
off-road. This is particularly the case when
the vehicle is heavily laden.
The maximum permissible distance that
can be driven in run-flat mode depends to
a large extent on the loads placed on the
vehicle. It can be shorter due to high
speeds, a heavy load, sudden acceleration
and/or manoeuvring, the road surface con-
dition, outside temperature, etc., or further
if you drive carefully and conservatively.
Do not continue to drive in run-flat mode if:
R you hear banging noises
R the vehicle starts to shake R
you see smoke and smell rubber
R ESP ®
is intervening constantly
R there

are tears in the sidewalls of the tyre
After driving in run-flat mode, you must
have the rims checked for damage at a
qualified specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. The faulty
tyre must be replaced in every case.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist work-
shop.
i On a vehicle with MOExtended tyres, only
MOExtended spare tyres should be used.
These must be of the size specified for the
vehicle. Practical advice
