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 461).
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:

clus ter (→ page 559)
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 re
ga uge. Notethat the cor rect tyre pressure for
