Tire pressure monitor
Concept
The system monitors tire inflation pressure in the
four mounted tires. The system warns you if
there is a loss of pressure in one or more tires.
General information
Sensors in the tire valves measure the tire infla‐
tion 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,
such as tires with special approval, the system
needs to be actively reset. The system will then
take over the actual tire inflation pressures as the
target pressures.
When operating the system, also note the infor‐
mation found in the Tire inflation pressure chap‐
ter.
Additional information:

Safety information
Warning
The display of the target pressures is not a
substitute for the tire inflation pressure details
on the vehicle. Incorrect entries in the tire set‐
tings can lead to incorrect target tire inflation
pressure values. In this case, it cannot be guar‐
anteed that the notification of a loss of tire infla‐
tion pressure will be reliable. There is a risk of
injury and risk of damage to property. Ensure
that the tire sizes of the mounted tires are dis‐
played correctly and match the details on the
tires and on the vehicle.
Functional requirements
The following conditions must be met for the
system; otherwise, reliable flagging of a loss of
tire inflation pressure is not assured:
▷ Every time a tire or wheel is changed, the
correct details on the mounted tires must be
entered in the tire settings.
▷ The Tire Pressure Monitor does not activate
until after driving for a few minutes:
▷ After a tire or wheel replacement.
▷ After a reset, for tires with special appro‐
val.
▷ After changing the tire setting.
▷ For tires with special approval:
▷ After a tire or wheel replacement, a reset
was performed with the correct tire infla‐
tion pressure.
▷ After the tire inflation pressure was ad‐
justed to a new value, a reset was per‐
formed.
▷ Wheels with wheel electronics.
