General notes If

vehicle's wheels have sensor sfitte dthat
monitor the tyr epressures in al lfou rtyres.
The tyr epressure monitor warns yo uifthe

Important safety notes It is the driver's responsibility to set the tyre
pressure to the recommende

sure suitabl efor the operating situation
(Y page 420). Note tha tthe correct tyr epres-
sure for the current operating situatio nmust
first be taught-i ntothe tyr epressure monitor.
If ther eisas ubstantial loss of pressure, the
warnin gthreshold for the warnin gmessage is

Restart the tyr epressure monitor after
adjusting to the col dtyrep ressure
(Y page 424). The current pressures are
saved as new reference values. Thi swill

appear if the tyr epressure drops significantly.
The tyr epressure monitor does not warn you
of an incorrectly set tyr epressure. Observe the note

If an emergency spare wheel is fitted, for a

Warning messages of the tyr epressure

sage is shown in the multifunction display and
the yellow tyre pressure monitor warning
lamp comes on.
R If the Please correc ttyre pressure

message appears in the multifunction dis- play, the tyre pressure in at least one tyre is
too low and must be corrected at the next
opportunity.
R If the Check tyre(s) Check tyre(s) message appears in
the multifunction display, the tyre pressure in one or more tyres has dropped signifi-
cantly and the tyres must be checked.
R If the Warnin gtyre defect
Warnin gtyre defect message
appears in the multifunction display, the
tyre pressure in one or more tyres has drop-

Observ ethe instructions and safety notes in
the display messages in the "Tyres" section
(Y page 322).
If the wheel position sonthe vehicle are inter-
changed, the tyre pressures may be displayed for the wrong position sfor as hort time. After
af ew minutes of driving, this is rectified and
the tyre pressures are displayed for the cor-
rect positions.
Restarting the tyr epressure monitor When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the refer-
enc evalues for monitoring. In most cases, the
tyre pressure monitor will automatically
detec tthe new referenc evalues after you
have changed the tyre pressure. However,
you can also define referenc evalues man-
ually as described here. The tyre pressure
monitor then monitors the new tyre pressure values.
X Use the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operatin gconditions.
Also observe the notes in the section on
tyre pressures (Y page 420).

ombinations General notes
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle. 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
specifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz.C er-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with aload, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components. This could result in dam- age to the tyres or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tyres,
wheels or accessories other than those tes-
ted and approved.
Further information about wheels, tyres
and approved combinations can be
obtained from any qualified specialist
workshop.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz,s ince
previous damage cannot alway sbedetec-
ted 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 com-
fort and suspension comfor tare reduced
and the risk of damage to the wheels and
tyres as aresult of driving over obstacles
increases. Wheel and tyrec
