ressure loss warning system
General notes While the vehicle is in motion
,the tyre pressure
loss warning system monitors the set tyre pres-
sure using the rotational speed of the wheels.
This enables the system to detect significant
pressure loss in atyre. If the speed of rotation of
aw heel changes as aresult of aloss of pressure,
ac orresponding warning message will appear in
the multifunction display.
You can recognise the tyre pressure loss warn-
ing by the Run Flat Indicator active
Run Flat Indicator active
Restart with OK Restart with OK message which appears in
the Service
Service menu of the multifunction display.
Information on the message display can be
found in the "Restarting the tyre pressure loss
warning system" section (Y page 358).
Important safety notes The tyre pressure warning system does not warn
you of an incorrectly set tyre pressure. Observe the notes on the recommended tyre pressure
(Y page 356).
The tyre pressure loss warning does not replace the need to regularly check the tyre pressures.
An even loss of pressure on several tyres at the
same time cannot be detected by the tyre pres-
sure 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 .Inthe event of
as udden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid abrupt steering
manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
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 (corner-
ing 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 vehi-
cle or on the roof).

Restarting the tyre pressure monitor When you restart the tyre pressure monitor, all
existing warning messages are deleted and the

values manually as described here. The tyre
pressure monitor then monitors the new tyre

awheel Flat tyre
You can find information on what to do in the
event of aflat tyre in the "Breakdown assis-
tance" section (Y page 337). Information on
driving with MOExtended tyres in the event of a flat tyre can be found under "Breakdown assis-
tance" (Y page 337).
Vehicles with an emergency spare wheel: in
the event of aflat tyre, the emergency spare
wheel is fitted according to the description
under "Fitting awheel" (Y page 362). Interchanging the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions. The wheel brakes or suspension components may also be damaged. There is arisk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions. !
On vehicles fitted with
atyre pressure mon-
itor, electronic componentsa re located in the
wheel.
Tyre-fitting tools should not be applied in the area of the valve, as this could damage the
electronic components.
Only have tyres changed at aqualified spe-
cialist workshop.
Interchanging the front and rear wheels of dif-
fering dimensions can render the general oper-
ating permit invalid.
Observe the instructionsa nd safety notes in the
"Fitting awheel" section (Y page 362).
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before aclear wear pat-
tern has formed on the tyres. Front tyres typi-
cally wear more on the shoulders and the rear
tyres in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure the direction of
rotation is maintained.
Cleant he 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 warn-
ing system (Y page 358) or the tyre pressure
monitor (Y page 360). Direction of rotation
Tyres with aspecified direction of rotation have
additional benefits, e.g. if there is arisk of aqua-
planing. These advantages can only be gained if
the tyres are fitted corresponding to the direc-
tion of rotation.
An arrow on the sidewall of the tyre indicates its correct direction of rotation. Storing wheels
Store wheels in acool, dry and preferably dark
place if they are not being used. Protect the
tyres against oil, grease, petrol and diesel. Changing

Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been approved for Mercedes-Benz vehicles and the respective
wheel.

ecombination
You can ask for information regarding permitted wheel-tyre combinations at aMercedes-Benz
Servic eCentre.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres and wheels
which have been approved by Mercedes-Benz specifically for your vehicle. These are specially adapted to the control
systems, such as ABS or ESP
®
and are
marked as follows:
R MO =Mercedes-Benz Original
R MOE =Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 =Mercedes-Benz Original (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tested
and approved by Mercedes-Benz.C ertain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with aload, tyre dimension variations
could cause the tyres to come into contact
with the bodywork and axle components.T his
could result in damage to the tyres or the
vehicle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tyres, wheels or accessories other than those tested and
approved.
Further information about wheels, tyres and
approved combinations can be obtained from
any qualified specialist workshop.
! Retreaded tyres are neither tested nor rec-
ommended by Mercedes-Benz,s ince previ-
ous damage cannot alway sbedetected on
retreaded tyres. As aresult, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tyres are fitted. Do not fit used tyres if you
have no information about their previous
usage.
! Large wheels: the lower the section width
for acertain wheel size, the lower the ride
comfor tisonp oor road surfaces. Roll comfort
and suspension comfor tare reduced and the
risk of damage to the wheels and tyres as a
result of driving over obstacles increases.
The recommended tyre pressures can be found
in the tyre pressure table on the fuel filler flap.
For further information on tyre pressure, see
(Y page 356). Check tyre pressures regularly
and only when the tyres are cold. 366

Notes on the vehicle equipment
–always fit the

R with tyres of the same size across an axle
(left/right)
R with the same type of tyres at agiven time
(summer tyres, winter tyres, MOExtended

Exception: it is permissible to fit adifferent

(Y page 337).
Vehicles with MOExtended tyres are not equip-
ped with aTIREFIT kit at the factory. It is there-
fore recommended that you additionally equip

WARNING
The wheel/tyre dimensions and the tyre type of the spare wheel/emergency spare wheel
and the wheel to be replaced may differ. Fit-
ting aspare wheel/emergency spare wheel
may severely impairt he driving characteris-
tics. There is arisk of accident.
To prevent hazardou ssituations:
R Adapt yourd riving style accordingly and
drive carefully.
R Never fit more than one spare wheel/emer-
gency spare wheel if the dimensions are
different to those of the wheel being

R Have the spare wheel/emergency spare
wheel in questionr eplaced at the nearest
qualifieds pecialist workshop. Make sure
that the wheel/tyre dimensions and tyre
type are correct. When using an emergency spare wheel or spare
wheel of adifferent size, you must not exceed
the maximum speed of 80 km/h.
Snow chains must not be fitted to emergency
spare wheels. General notes
You can ask for information regarding permitted
emergency spare wheelsataM ercedes-Benz
Service Centre.
You shouldr egularly check the pressure of all
yourt yres, including the emergency spare
wheel,p articularly prior to long trips, and cor-
rect the pressure as necessary (Y page 356).
The valueont he wheel is valid.
An emergency spare wheel may also be fitted
against the direction of rotation. Observe the
time restriction on use as well as the speed lim- itation specifie donthe emergency spare wheel.
Replace the tyres after six years at the latest,
