Vehicles with the MOExtended run-flat
system are not equipped with the TIREFIT
kit. 36
It is therefore recommended to additionally
equipy ourvehicle with the TIREFIT kit when
fitting tyres that do not feature run-flat
properties, e.g. winter tyres.
i ATIREFIT kit is availablef rom any quali-
fied specialist workshop, e.g. aMercedes-
Benz Service Centre.
You willf ind notes on driving with aflat tyre
in the "Practical advice" section
(Y page 272). 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 3mm.
Thus, you should replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4mmorless as they will no
longer provide adequate grip.
R the tread on atyre may not wear evenly.
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 front wheelstof ull lock in order to
inspect the tyre tread more easily.
Otherwise, you could 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 willf indatable of tyre pressures for
variouso perating conditions on the inside
of yourv ehicle's fuel filler flap. The applicable valuef
or the "Minispare"
emergency spare wheel*i sstated on the
spare wheel and in the technical data sec-
tion.
The load condition "partially laden" or "fully
laden" is defined in the table by the differing
number of passengers and amount of lug-
gage. The actual number of seats may vary
from this –more information can be found on
the vehicle's registration document.
If no other data is stated, the tyre pressures
specified on the fuel filler flap applyf or all
tyres approved for this vehicle. If
at yre size precedes atyre pressure, the tyre
pressure information following is only valid
for that tyre size. Instead of the complete tyre size, it may be
that only the rim diameter is stated, e.g.

Press the 0064button.
The tyre pressure values stored at the last
restart will continue to be monitored. Interchanging the wheels
G
Risk of accident
Interchange the fron tand rear wheels only if
they have the same dimensions :for example
size, offset ,etc.
After awheel is changed, have the tightening
torque checked at aspecialist workshop that
has the necessary specialist knowledge and
tools to carry out the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Servic eCentre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
The wheels could work loose if they are not
tightened to atorque of 130 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correc tsize which have been approved for
Mercedes-Benz vehicles.
The wear patterns on the fronta nd rear tyres
differ, depending on the operating conditions.
Interchange the wheels before aclear wear
patter nhas formed on the tyres. Frontt yres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size fronta nd
rear wheels you can interchange the wheels
every 5,000 km to 10,00 0kmdepending on
the degree of tyre wear. Do not reverse the
direction of tyre rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time awheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system*. Winter driving
Points to remember
Have your vehicle winterproofed at aqualified
specialist workshop, e.g. at aMercedes-Benz
Servic eCentre, at the onset of winter.
Observe the notes in the "Changing awheel"
section (Y page 189). Winter tyres
Use winter tyres at temperatures below
+7 ˚C and in wintry road conditions. Only
winter tyres displaying the 004Dsnowflake
symbol in addition to the M+S markin gpro-
vide optimum grip in wintry road conditions.
Only these tyres will allow the ABS and ESP
driving systems to function optimally in win-
ter, as these tyres have been designed spe-
cifically for driving on snow.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
Winter tyres with atread depth of less than
4mmm ust be replaced immediately. They are
no longer suitable for winter use and can no
longer provide sufficient grip. This could
cause you to lose control of your vehicle and
cause an accident.
Always observe the maximum permissible
speed specified for the winter tyres you have
fitted. If you fit winter tyres which have a
lower maximum permissible speed than that
of the vehicle, affix an appropriate warning
sign in the driver's field of vision. This can be
obtained at aqualified specialist workshop,
e.g. from aMercedes-Benz Servic eCentre.
Under these circumstances, you should also
restrict the maximum speed of the vehicle
using permanen tSpeedtronic 37
to the maxi-
mum permissible speed for the winter tyres
(Y page 135).

Once you have fitted the winter tyres:
X
Check the tyre pressures (Y page 186).
X Restart the tyre pressure loss warning sys-
tem (Y page 187). G
Risk of accident
If you fit the spare wheel* when driving with
winter tyres, bear in mind that driving stability
will be impaired owing to unstable cornering
characteristics caused by the different tyres.
You should therefore adapty our driving style
and drive carefully.
Have the spare wheel* replaced at the near-
est qualified specialist workshop which has
the necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use aMercedes-
Benz Service Centre for this purpose. In par-
ticular, work relevant to safety or on safety-
related systems must be carried out at aquali-
fied specialist workshop. Snow chains
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains which
have been speciallya pproved for your vehicle
by Mercedes-Benz,ora re ofacorresponding
standard of quality.
If you intend to fit snow chains, pleaseb ear
the following points in mind:
R you may not attach snow chains to all
wheel-tyre combinations; see the "Tyres
and wheels" section in the "Technical data"
chapter.
R snow chains must not be fitted to emer-
gency spare wheels, e.g. a"Minispare"
emergency spare wheel.
R Fit snow chains only in pairs and only to the
rear wheels. Comply with the manufactur-
er's installation instructions.
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate ESP ®
when
pulling awayw ith snow chains fitted (Y
page 54). This way,y ou can allowthe
wheels to spin in acontrolled manner, ach-
ieving an increased driving force (cutting
action). Winter driving
G
Risk of accident
Do not shift down for additional engine brak-
ing on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission: engage
neutral.
X Vehicles with automatic transmission*:
shift the selector lever to N.
X Try to bring the vehicle under control by
using corrective steering. Driving tips
Rolling with the engines
witchedoff G
Risk of accident
Never switch the engine off while the vehicle
is in motion.
There is no power assistance for the steering
and the service brake when the engine is not
running.
You will require considerably more effort to
steer and brake and you could therefore lose
control of the vehicle and cause an accident. 190
