Depending on the tires detected or registered,
the system displays the specified nominal
pressures on the control display and compares
them with the current tire pressures.
If tires are being used that are not specified
in the tire inflation pressure details on the ve-
hicle such as tires with special approval, the
system needs to be actively reset. The system
will then take over the actual tire inflation pres-
sures as the target pressures.
When operating the system, also note the in-
formation found in the Tire inflation pressure
chapter.
Additional information:
Tire inflation pressure, refer to page 288.
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
inflation pressure values. In this case, it can-
not be guaranteed that the notification of a
tire pressure loss will be reliable. There is a
risk of injury and risk of damage to property.
Make sure that the sizes of your mounted
tires are displayed correctly and match the
information on the tires and the tire inflation
pressure specifications on the vehicle.
Functional requirements
The following prerequisites must be met for
the system; otherwise, reliable notification of a
tire pressure loss is not assured:
▷
After each tire or wheel change, the system
detects and updates the mounted tires on
the control display and displays them after
a short trip.

Wheels and tires
Enter the information about the mounted
tires in the tire settings when the system
does not automatically detect the tires.
▷
The Tire Pressure Monitor does not acti-
vate until after driving for a few minutes:
▷
After a tire or wheel change.
▷
After a reset, when using tires with spe-
cial approval.
▷
After changing the tire setting.
▷
For tires with special approval:
▷
After a tire or wheel change, a reset 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 air pressure sensor.
Tire settings
General information
The information about the mounted tires can
be entered in the tire settings if the system
does not automatically detect the tires.
The tire sizes of the mounted tires can be
gathered from the tire inflation pressure details
on the vehicle or directly on the tires.
The tire details do not need to be re-entered
when the tire pressure is corrected.
For summer and winter tires, the tire details
entered last are stored. After a tire or wheel
change, the settings of the tire sets used last
can be selected.
