nction of the ty repressure moni toring sys‐
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 573).
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:

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 suitable
forth e operating situation. Set the tyre
pressure for cold tyres using a tyre pressu re
ga uge. No tethat the cor rect tyre pressure for

The sy stem may be impaired or may not function
in thefo llowing situations:
