cle. The recommended tyre pressures apply for
cold tyres under various operating conditions,
i.e. loading and/or speed of the vehicle.
If one or more tyre sizes precede a tyre pres‐
sure, the tyre pressure information following is
only valid for those tyre sizes.
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.
If there is a substantial pressure loss or if the
tyre temperature is excessive, a warning will be
given:
R
via display messages (

page 448)
R
via the h warning lamp in the instrument
cluster (

It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pressure
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 (

page 394).
System limitations
The system may be impaired or may not function
in the following situations:
R
if the tyre pressure is set incorrectly
R
if there is a sudden pressure loss caused, for
example, by a foreign object penetrating the
tyre
R
if there is a malfunction caused by another
radio signal source
