tem
The sy stem checks the tyre pressure and the
tyre temp erature of the tyres fitted totheve hicle
by means of a tyre pressu resensor.
New tyre pressure sensors, e.g. in winter tyres,
are automatically taught-in during thefirs t jour‐
ney they are used.
The tyre pressure and the tyre temp erature
appear in the multifunction display
(/ page 505).
If th ere is a subs tantial pressure loss or if the
tyre temp erature is excessive, you will be
wa rned in thefo llowing ways:
R via display messa ges (/ page576)

The tyre pressu remonitoring sy stem is only an
aid. It is the driver's responsibility toset the tyre
pressure tothere commended cold tyre pressure

pressure for cold tyres using a tyre pressu rega
uge. Notethat the cor rect tyre pressure for

R Countr y-specific requirements for tyre
appro valth at define a specific tyre type for
yo ur vehicle.
Fu rthermore, the use of cer tain tyre types in
cer tain regions and areas of operation can
be highly beneficial.
R Only use tyres and wheels of the same type
(summer tyres, winter tyres, MOEx tended
tyres) and the same make.
R Only fit wheels of the same size on one axle
(left and right).
It is only permissible tofit a di fferent wheel
size in theeve nt of a flat tyre in order to
drive tothe specialist workshop.
R Only fit tyres of the cor rect size onto the
wheels.
R Do not make any modifications tothe brake
sy stem, the wheels or the tyres.
The use of shims or brake dust shields is not
permitted and may in validate theve hicle's
ge neral operating pe rmit. R

R Attemp eratures below 7 °C, use winter tyres
or all-season tyres mar ked M+S for all
wheels.
Wi nter tyres bearing thei snowflake
symbol in addition tothe M+S marking pro‐
vide the best possible grip in wintry road
conditions.
R For M+S tyres, only use tyres with the same
tread.
R Obser vethe maximum permissible speed for
th e M+S tyres fitted.
If th is is below theve hicle's maximum speed,
th is must be indicated byan appropriate
label in the driver's field of vision.
R Run in new tyres at moderate speeds forthe
fi rs t10 0 km.
R Replace the tyres af ter six years at the latest,
re ga rdless of wear. R
When replacing with tyres that do not
fe ature run-flat characteristics: vehicles
with MOExtended tyres are not equipped
with a TIREFIT kit at thefa ctor y.Equip the
