General information
Sensors in the tire valves measure the tire in‐
flation pressure and tire temperature.
Using the tire settings in iDrive, the system can
automatically display the specified target pres‐
sures and compare them with the actual tire in‐
flation pressures.
If tires are being used that are not specified on
the tire inflation pressure details on the vehicle,
refer to page 260, such as tires with special
approval, the system needs to be actively re‐
set. The system will then take over the actual
tire inflation pressures as the target pressures.
When operating the system, also note the ad‐
ditional information found in the Tire inflation
pressure, refer to page 260, chapter.
Safety information
WARNING
The display of the target pressures is not
a substitute for the tire inflation pressure de‐
tails on the vehicle. Incorrect entries in the tire
settings can lead to incorrect target tire infla‐
tion pressure values. In this case, it cannot be
ensured that the notification of a tire inflation
pressure loss is reliable. There is a risk of injury
and risk of damage to property. Ensure that the
tire sizes of the mounted tires are entered cor‐
rectly and match the details on the tires and on
the vehicle.◀
Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐
wise, reliable flagging of a flat tire is not as‐
sured:
▷ Every time a tire or wheel is changed, the
correct details on the mounted tires must
be entered in the tire settings, refer to
page 274.
▷ For tires with special approval:

▷ After a tire or wheel replacement, a re‐
set was performed with the correct tire
inflation pressure.
▷ After the tire inflation pressure was ad‐
justed to a new value, a reset was per‐
formed.
▷ Wheels with TPM electronics.
Tire settings
General information
The tire sizes of the mounted tires can be
gathered from the tire inflation pressure details
on the vehicle, refer to page 260, or directly on
the tires.
The tire details do not need to be re-entered
when the tire inflation pressure is corrected.
For summer and winter tires, the tire details
entered last are stored. After a tire or wheel re‐
placement, the settings of the tire sets used
last can be selected.
