If the preceding tyre sizes are complemented by
the + symbol, the tyre pressure information
following shows alternative tyre pressures.
These tyre pressures may improve your vehicle's
ride comfort. 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 and the
tyre temperature 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 during the first jour‐
ney they are used.
The tyre pressure and the tyre temperature
appear in the multifunction display
( page 511).

If there is a substantial pressure loss or if the
tyre temperature is excessive, you will be
warned in the following ways:
via display messages (
R
via the h warning lamp in the instrument
R
cluster (
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
page 509)
suitable for the operating situation. Set the tyre
pressure 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 sys‐
tem.
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 (
