only reach their full performanc
eafter this
distance.
R Fit new tyres on the front wheels first if
tyres of the same size are required on the
front and rear wheels.
R Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the spare wheel*.
R Do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
! Storet yres that are not being used in a
cool, dry and preferably dark place. Protect
the tyres against oil, grease, petrol and die-
sel.
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, bulges on tyres and deformation,
cracksors evere corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause aloss 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 186). 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 avalve cap to protect
the valve against dirt and moisture. Do not
fit anything ontot he valve (such as tyre
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Benz for your vehi-
cle.
R Regularly check the pressure of all the tyres
including the spare tyre* ,particularly prior
to long trips, and correc tthe pressure as
necessary (Y page 186). 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 atyre 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 examined
at as pecialist workshop, for example at a
Mercedes-Benz Servic eCentre.
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 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 aspecified direction of rotation
have additional benefits, e.g. if there is arisk
of aquaplaning. You will only gain these ben-
efits if the correc tdirection of rotation is
observed.
An arrow on the sidewal lofthe tyre indicates
its correc tdirection 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 activated tyre
pressure loss warning system and only on
wheels specifically tested and approved by
Mercedes-Benz. Tyres and wheels

The tyre pressure loss warning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detected by the tyre pressure loss
warning system.
The tyre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign object.
In the event of asudden loss of pressure, bring
the vehicle to ahalt by braking carefully. Do
not make any sudden steerin gmovements
when doing so.
The function of the tyre pressure loss warning
system is limited or delaye dif:
R snow chains are fitted to your vehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt avery sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you are towing avery heavy or large trailer.
R you are driving with aheavy load (in the
vehicle or on the roof).

R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler flap
to ensure that the tyre pressure in all four
tyres is set correctly for the respective
operating conditions.
X Observe the notes in the section on tyre
pressures (Y page 186). G
Risk of accident
The tyre pressure loss warning system can
only give reliable warnings if you have set the
correc ttyre pressure.
If an incorrect tyre pressure is set, these
incorrect values will be monitored.
At yre with insufficien tpressure results in
vehicle instability when driving, thus increas-
ing the risk of an accident.

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
