542 Wheels and tyres
If the preceding tyre sizes are complemented by
the + symbol, the tyre pressure information
following shows alternative tyre pressures. Fuel
consumption may then increase slightly.
The load conditions "partially laden" and "fully
laden" are defined in the table for different num-
bers of passengers and amounts of luggage. The
actual number of seats may differ from this.
Tyre pressure monitoring system
▌Function of the tyre pressure monitoring sys-
tem
The system checks the tyre pressure of the tyres
fitted to the vehicle by means of a tyre pressure
sensor.
New tyre pressure sensors, e.g. in winter tyres,
are automatically taught-in the first time they are
driven.
The tyre pressure appears in the multifunction dis-
play ( page 353).
/
If there is a substantial pressure loss or if the tyre
temperature is excessive, a warning will be given:
Via display messages ( page 746).
/
R
Via the h warning lamp in the instrument
R
cluster .
It is the driver's responsibility to set the tyre pres-
sure to the recommended cold tyre pressure suit-
able for the operating situation. Set the tyre pres-
sure for cold tyres using a tyre pressure gauge.
Note that the correct tyre pressure for the current
operating situation must first be taught-in to the
tyre pressure monitoring system.
In most cases, the tyre pressure monitoring sys-
tem will automatically update the new reference
values after you have changed the tyre pressure.
You can, however, also update the reference val-
ues by restarting the tyre pressure monitoring
system manually ( page 543).

System limitations
