Tire pressure monitoring learning phaseEach time a wheel is changed, the tire pressure
monitoring must complete the learning phase
again. The tire pressure monitoring identifies the
wheel positions in this process.
The current tire pressures will not be available on
the multi-purpose display until the learning phase
is complete.
tire pressure monitoring learning process
fSelect tire type and tire size in the menu TIRE
PRESSURE > SETTINGS > TIRES.
The learning process is started. The tire type
and size must be selected e ve n if the se ttings
for the new set of wheels are the same as for
the old wheels.Note
The spare wheel and collapsible spare wheel do
not contain a wheel transmitter and are not moni-
tored by the tire pressure monitoring.
The tire pressures for cold tires (68°F/20°C) are
shown in the TIRE PRESSURE menu (filling informa-
tion) during the learning phase.
The required pressure for the spare wheel is al-
ways displayed in the TIRE PRESSURE menu (filling
information).
fCheck the tire pressure for the spare wheel
and collapsible spare wheel manually.
Tire pressure filling informationTire pressure menuThe TIRE PRESSURE menu provides an overview
of the current pressure specifications for the re-
spective wheel (filling information). The pressure
differences with respect to the required pressure
are specified irrespective of the tire temperature.
If the wheels have not been learned, the current
pressures are unavailable.
The spare wheel is not monitored. The required
pressure is specified in brackets.
To make changes to the settings of the tire pres-
sure monitoring, select SETTINGS in the TIRE
PRESSURE menu.

Monitoring is not active when:
– the tire pressure monitoring is faulty,
– wheel transmitters for the tire pressure
monitoring are not present,
– temporarily after changing a wheel,
