The system checks the tyre pressure and the tyre
te mp erature of the tyres /t tedtotheve hicle by
means of a tyre pressure sensor.
The tyre pressure and the tyre temp erature
appear in the on-board computer (/ page 341).
If th ere is a substantial pressure loss or if the tyre
te mp erature is excessive, you will be warned with
display messages (/ page 421) ortheh
wa rning lamp in the inst rument cluster
(/ page 444).
The tyre pressure monitoring system is only an
aid. It is the driver's responsibility toset the tyre pressure
tothere commended cold tyre pressure
suitable forth e operating situation.
In most cases, the tyre pressure monitoring sys-
te m will automatically update the new refere nce

Yo u can, ho wever, also update there fere nce val-
