If one or more tyre sizes precede a tyre pres‐
sure, the following tyre pressure information is
only valid for those tyre sizes and their respec‐
tive 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 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 tyre pressure and the tyre temperature
appear in the multifunction display
(/ page 494).
If there is a substantial pressure loss or if the
tyre temperature is excessive, you will be
warned in the following ways:
R
via display messages (/ page 626)
R
via the h warning lamp in the instrument
cluster (/ page 649)
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 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 495).
System limits
The system may be impaired or may not function
in the following situations:
R
the tyre pressure has been set incorrectly
R
there is a sudden pressure loss caused, for
example, by a foreign object penetrating the
tyre
R
there is a malfunction caused by another
radio signal source
Checking the tyre pressure with the tyre
pressure monitoring system
Requirements:
R
The ignition is switched on.
