Breakdown assis tance

The system checks the tire pressure and the tire
te mp erature of the tires fitted totheve hicle by
means of a tire pressure sensor.
New tire pressure sensors, e.g. in winter tires,
are automatically taught-in thefirs t time they are
driven.
The tire pressure and the tire temp erature
appear in the multifunction display
(
→page 202).
If th ere is a subs tantial pressure loss or if the
tire temp erature is excessive, a warning will be
given:
RVi a display messages (→page 425).
RViath e0077 warning lamp in the instrument
clus ter (→page 459).
It is the driver's responsibility toset the tire
pressure tothere commended cold tire pressure
suitable forth e operating situation. Set the tire
pressure for cold tires using a tire pressure
ga uge. Notethat the cor rect tire pressure forth e
cur rent operating situation must firs t be taught-
in to the tire pressure monitoring sy stem. In most cases,
the tire pressure monitoring sys‐
te m will auto matically update the new refere nce
va lues af teryo u ha vechanged the tire pressure.
Yo u can, ho wever,also update there fere nce val‐
ues byrestarting the tire pressure mon
