If one or more tyre sizes precede a tyre pressure,
the following tyre pressure information is only
valid for those tyre sizes and their respective load
condition.
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 de ned in the table for di erent num-
bers of passengers and amounts of luggage. The
actual number of seats may di er from this.

The system checks the tyre pressure and the tyre
temperature of the tyres tted to the vehicle by
means of a tyre pressure sensor.
The tyre pressure and the tyre temperature
appear in the on-board computer (
/
page 368).
If there is a substantial pressure loss or if the tyre
temperature is excessive, you will be warned with
display messages (
/
page 459) or the h
warning lamp in the instrument cluster
(
/
page 483).
The tyre pressure monitoring system is only an
aid. It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pressure
suitable for the operating situation.
In most cases, the tyre pressure monitoring sys-
tem will automatically update the new reference
values a er you have changed the tyre pressure.
You can, however, also update the reference val-
ues by restarting the tyre pressure monitoring
system manually (

page 369).
