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 damag
e
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 th e
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 combination with the tyre pressure
loss warning system and only on wheels spe-
cifically tested and approved by Mercedes-
Benz.
i Vehicles with MOExtended run-flat sys-
tem* are not equipped with the TIREFIT
kit*. 14 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.
You will find notes on driving with a flat tyr e
in the "Practical advice" section
( Y page 323). 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 th e
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

3 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 caus e
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.
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 204). 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.
The pressure of warm tyres should only be
corrected if it is too low for the current oper-
ating conditions. You will find a table of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
Driving with tyre pressure that is too high or
too low can:
R
shorten the service life of the tyres
R cause increased tyre damag e
R have a negative effect on handling charac-
teristics (e.g. by causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics .
You can, however, also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle.
Also check the tyre pressure of the spare
wheel* . H
Environmental not
e
Check the tyre pressure regularly, and at
least every 14 days. Operation

Risk of injury
The jack is designed only to raise and hol d
the vehicle for a short time while a whee l
is being changed.
If you are carrying out work on the vehicle,
you must use stands.
Make sure that the jack is placed on a firm ,
non-slip and level surface. Do not us e wooden blocks or similar objects as a jac
k
underlay. Otherwise the jack will not be
able to achieve its load-bearing capacit y
due to the restricted height.
Do not start the engine at any time while a
wheel is being changed.
Do not lie under the vehicle when it is bein g
supported by the jack. If you do not raise
the vehicle as described, it could slip off the
jack (e.g. if the engine is started or a door
or the boot lid is opened or closed) and you
could be seriously injured.

X Depending on the size of the wheel, yo u
may also be able to secure the faulty whee l

will have to remove the stowage well casin g
from the spare wheel well and stow it
securely in the boot/luggage compart-
ment. MOExtended run-flat system*
The MOExtended run-flat system* must only
be used in conjunction with the tyre pressure
loss warning system*.
! 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 permissible distance which
can be driven in run-flat mode is counted
from the moment the tyre pressure loss
warning 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 vehicl e
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 tyr e
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 Practical advice
